Long-term outcome for patients with nonmetastatic osteosarcoma of the extremity treated at the istituto ortopedico rizzoli according to the istituto ortopedico rizzoli/osteosarcoma-2 protocol: an updated report.

PURPOSE: To provide an estimate of long-term prognosis for patients with osteosarcoma of the extremity treated in a single institution with neoadjuvant chemotherapy and observed for at least 10 years. PATIENTS AND METHODS: Patients with nonmetastatic osteosarcoma of the extremity were preoperatively treated with high-dose methotrexate, cisplatin, and doxorubicin (ADM). Postoperatively, good responders (90% or more tumor necrosis) received the same three drugs used before surgery, whereas poor responders (less than 90% tumor necrosis) received ifosfamide and etoposide in addition to those three drugs. RESULTS: For the 164 patients who entered the study between September 1986 and December 1989, surgery was a limb salvage in 136 cases (82%) and a good histologic response was observed in 117 patients (71%). At a follow-up ranging from 10 to 13 years (median, 11.5 years), 101 patients (61%) remained continuously free of disease, 61 relapsed, and two died of ADM-induced cardiotoxicity. There were no differences in prognosis between good and poor responding patients. ADM-induced cardiotoxicity (six patients), male infertility (10 of the 12 assessable patients), and second malignancies (seven patients) were the major complications of chemotherapy. Despite the large number of limb salvages performed, only four local recurrences (2.4%) were registered. CONCLUSION: With an aggressive neoadjuvant chemotherapy, it is possible to cure more than 60% of patients with nonmetastatic osteosarcoma of the extremity and amputation may be avoided in more than 80% of them. Because local or systemic relapses, myocardiopathies, and second malignancies are possible even 5 years or more after the beginning of treatment, a long-term follow-up is recommended for these patients.

Adjuvant radiation for stage II-B soft tissue sarcoma of the extremity.

PURPOSE: Adjuvant radiation therapy (RT) has been shown to improve local control in patients with high-grade soft tissue sarcoma (STS) of the extremity. This study sought to define the optimal management in patients with stage II-B (high-grade, size < or = 5 cm) tumors. PATIENTS AND METHODS: Between July 1982 and December 1998, 204 adult patients with primary stage II-B STS underwent limb-sparing surgery with negative microscopic margins. Eighty-eight patients (43%) received RT; 116 (57%) did not. The RT and no-RT groups were balanced with regard to age, site (upper v lower extremity), whether patients had prior unplanned excision, and location (central, i.e., shoulder/groin v non-central). The RT group had more deep tumors (P =.03). Adjuvant RT was delivered with brachytherapy in 60% and external-beam radiation in 40% of patients. RESULTS: With a median follow-up of 67 months, the 5-year local control, distant relapse-free survival, and disease-specific survival rates were 82%, 80%, and 88%, respectively. There was no significant difference in local control between the RT and no-RT groups (84% v 80%, respectively, P =.3). Tumor depth, site, and prior unplanned excision did not correlate with local control. The only independent predictors of poor local control were central tumor location (relative risk [RR] = 3; 95% confidence interval [CI], 2 to 7; P =.005) and age more than 50 years (RR = 6; 95% CI, 2 to 13; P =.001). CONCLUSION: In this retrospective study, adjuvant RT did not significantly improve local control in patients with stage II-B STS of the extremity. The outcome of patients with central tumor location was poor, and efforts to identify the optimal local treatment approach for such patients are warranted.

Adjuvant brachytherapy for primary high-grade soft tissue sarcoma of the extremity.

BACKGROUND: We reviewed single-institution experience using brachytherapy alone for primary high-grade soft tissue sarcoma of the extremity. METHODS: Between July 1982 and September 1997, 202 adult patients with primary high-grade soft tissue sarcoma of the extremity were treated with limb-sparing surgery and adjuvant brachytherapy. All patients underwent complete gross resection, but the margin of resection was microscopically positive in 18% of patients. The median dose of brachytherapy was 45 Gy delivered over 5 days. Tumors located in the shoulder or groin were defined as central location. Complications were assessed in terms of wound complications, bone fracture, and peripheral nerve damage. RESULTS: With a median follow-up of 61 months, the 5-year local control, distant relapse-free survival, and overall survival rates were 84%, 63%, and 70%, respectively. On multivariate analysis, poor local control correlated with shoulder location, positive microscopic margins of resection, and nonshoulder upper extremity site. The 5-year actuarial rates of wound complications requiring reoperation, bone fracture, and grade > or = 3 nerve damage were 12%, 3%, and 5%, respectively. CONCLUSIONS: Adjuvant brachytherapy provides adequate local control and acceptable morbidity that compares favorably with data reported for external beam radiation. Shoulder tumor location was identified as an independent prognostic factor for poor local control, mandating further improvement in the local management of these tumors.

Pulsed dose-rate perioperative interstitial brachytherapy for soft tissue sarcomas of the extremities and skeletal muscles of the trunk.

BACKGROUND: This study evaluated the role of pulsed dose-rate (PDR) brachytherapy (BRT), delivered alone or as a boost to external beam radiotherapy, as adjuvant therapy for the local control of soft tissue sarcomas of the extremities and skeletal muscles of the trunk that have undergone surgical treatment. METHODS: Between July 1998 and January 2002, 42 patients were treated with a combination of surgery and BRT alone (18 patients) or BRT/external beam radiotherapy (24 patients) for the treatment of primary (n = 32) and recurrent (n = 10) soft tissue sarcomas located in the proximal extremity (n = 17), distal extremity (n = 17), and trunk (n = 8). Tumor size was <5 cm in 20 cases and >5 cm in 22 cases, with histological grading of 1 (n = 7), 2 (n = 18), or 3 (n = 17). The median BRT dose delivered was 15 Gy, and the median external beam irradiation dose was 50 Gy. RESULTS: With a median follow-up of 34 months, the 36-month survival was 83.9% (SE, 6.1%), and the local control was 89%. CONCLUSIONS: PDR interstitial BRT for soft tissue sarcoma is an effective, well-tolerated adjuvant radiation treatment that offers several practical advantages, among which are low acute and late toxicity with maximum normal tissue and critical structure sparing and overall shorter radiotherapy and hospital stay.

Prognostic effect of re-excision in adult soft tissue sarcoma of the extremity.

BACKGROUND: We explored the outcome of patients with primary adult soft tissue sarcoma (STS) of the extremities undergoing re-excision after previous unplanned surgery. METHODS: A total of 597 consecutive adult patients with primary extremity STS were treated with conservative surgery at our institution over a 20-year time span. A total of 318 patients were referred after unplanned excisions, and the remaining 279 underwent primary resection at our center. The two groups significantly differed in tumor size and depth. The assessed end points were sarcoma-specific mortality, local recurrence, and distant metastasis. Univariable and multivariable analyses, adjusted for other prognostic factors, were performed in the competing risks framework. RESULTS: The adjusted 10-year cumulative incidences in re-excised and primarily operated patients were, respectively, 18.7% and 16.4% (P = .535) for local relapse, 17.6% and 20.2% (P = .541) for metastasis, and 20.4% and 22.4% (P = .645) for mortality. Among patients who underwent re-excision, evidence of microscopic residual disease on pathologic examination had a significant prognostic effect on multivariable analysis for distant metastases (P = .002). A trend for survival was detected as well. CONCLUSIONS: At a referral center with a liberal policy of re-excisions in adult primary STS of the extremities, the outcome of patients who underwent re-excision was similar to that of patients who had primary resections. Evidence of microscopic residual disease at re-excision was a marker of clinical aggressiveness.

Effect of inverted orthoses on lower-extremity mechanics in runners.

INTRODUCTION: Foot orthoses are recommended for individuals with injuries associated with abnormal lower-extremity mechanics. However, the biomechanical effect of these devices is not completely understood. Most clinicians and researchers believe that foot orthoses are effective in reducing some aspect of rearfoot motion. This is important as many injuries are suggested to be the result of increased pronation. Inverted orthoses are a more aggressive treatment in those whose symptoms do not respond to standard orthotics. They are likely to alter motion in all planes. However, no three-dimensional studies have assessed lower-extremity mechanics in individuals wearing inverted orthotics. PURPOSE: The purpose of this study was to compare the three-dimensional kinematics and kinetics of the rearfoot and knee during running while varying orthotic intervention. METHODS: Eleven subjects were initially fitted with standard foot orthoses and then with inverted orthoses. Three-dimensional kinematic and kinetic data were collected for conditions of no orthoses, standard orthoses, and inverted orthoses. RESULTS: There were no differences between conditions in peak rearfoot eversion or rearfoot eversion excursion. Peak rearfoot inversion moment and work were significantly reduced (P = 0.045 and P < 0.001, respectively) in the inverted orthotic condition suggesting a decreased demand on the soft tissue structures that control eversion. Significant differences were seen in tibial rotation (P = 0.043), knee adduction (P = 0.035), and knee abduction moment (P < 0.001) in the inverted orthotic condition, suggesting alterations were made further up the kinetic chain. CONCLUSIONS: The differences in kinetic parameters at the rearfoot may result in fewer injuries of the rearfoot soft tissue structures when using inverted orthotics. These alterations in lower-extremity mechanics associated with inverted orthoses provide clinicians some evidence for prescribing this device.

Core strength and lower extremity alignment during single leg squats.

INTRODUCTION/PURPOSE: Muscles of the trunk, hip, and knee influence the orientation of the lower extremity during weight bearing activities. The purpose of this study was threefold: first, to compare the orientation of the lower extremity during a single leg (SL) squat among male and female athletes; second, to compare the strength of muscle groups in the trunk, hips, and knees between these individuals; and third, to evaluate the association between trunk, hip, and knee strength and the orientation of the knee joint during this activity. METHODS: Twenty-four male and 22 female athletes participated in this study. Peak isometric torque was determined for the following muscle actions: trunk flexion, extension, and lateral flexion, hip abduction and external rotation, and knee flexion and extension. The frontal plane projection angle (FPPA) of the knee during a 45 degrees SL squat was determined using photo editing software. RESULTS: Males and females moved in opposite directions during the SL squat test (F(1,42) = 5.05, P = 0.03). Females typically moved toward more extreme FPPA during SL squats (P = 0.056), while males tended to move toward more neutral alignment (P = 0.066). Females also generated less torque in all muscle groups, with the exception of trunk extension. The projection angle of the knee during the SL squat test was most closely associated with hip external rotation strength. CONCLUSION: Using instruments suitable for a clinical setting, females were found to have greater FPPA and generally decreased trunk, hip, and knee isometric torque. Hip external rotation strength was most closely associated with the frontal plane projection angle.

Residual disease following unplanned excision of soft-tissue sarcoma of an extremity.

Sixty-five patients who had been referred to our unit for additional management after an unplanned excision of a soft-tissue sarcoma of an extremity at another institution were studied retrospectively to determine the prevalence of residual tumor and to identify factors that predict which patients will have a tumor following such an excision. Unplanned excision was defined as excisional biopsy or unplanned resection of the lesion without benefit of preoperative imaging and without regard for the necessity to resect the lesion with a margin of normal tissue. In each patient, histological evaluation of the specimen removed at the unplanned excision had demonstrated positive resection margins, but postoperative physical examination on our unit revealed no gross evidence of residual tumor and no tumor was identified on cross-sectional imaging of the local site. Patients who had evidence of residual disease on physical examination or on imaging were thought to have definite evidence of sarcoma at the site of the operative wound and were therefore excluded from the study. After multidisciplinary consultation, all patients had a repeat resection at our cancer center. Extensive pathological sampling of the specimen from this second procedure was carried out, with sections obtained at mean intervals of 1.2 +/- 0.7 centimeters. Nodules initially thought to indicate disease were identified grossly in twenty-seven (42 percent) of the sixty-five patients, but histological evaluation confirmed the presence of tumor in only sixteen (59 percent). Histological evidence of sarcoma was identified in seven additional patients in whom gross nodules were not apparent in the specimen. Thus, sarcoma was identified in a total of twenty-three (35 percent) of the sixty-five patients. The mean duration of follow-up was forty-six months (range, twenty-four to eighty months; median, thirty-nine months). The margins of the second resection were positive in nine (39 percent) of the twenty-three patients who had residual sarcoma. Five (22 percent) of the twenty-three had a local recurrence. Four of the five patients who had a local recurrence had positive margins on repeat resection. This rate of local recurrence (five of twenty-three patients) was significantly higher than that in the remainder of our patients who had a soft-tissue sarcoma of an extremity (sixteen [7 percent] of 227) (p = 0.03). There was no association between the detection of sarcoma at the second procedure and the initial size or grade of the tumor, the use of irradiation preoperatively, or the interval between the initial, unplanned excision and referral to our cancer center. These data indicate that it is not possible to predict which patients will have residual tumor at the site of the operative wound. Therefore, it is prudent to advise repeat excision for all patients who have had an unplanned excision of a soft-tissue sarcoma of an extremity. Unplanned excision complicates decision-making in the treatment of this disease and should be avoided.

The insensate foot following severe lower extremity trauma: an indication for amputation?

BACKGROUND: Plantar sensation is considered to be a critical factor in the evaluation of limb-threatening lower extremity trauma. The present study was designed to determine the long-term outcomes following the treatment of severe lower extremity injuries in patients who had had absent plantar sensation at the time of the initial presentation. METHODS: We examined the outcomes for a subset of fifty-five subjects who had had an insensate extremity at the time of presentation. The patients were divided into two groups on the basis of the treatment in the hospital: an insensate amputation group (twenty-six patients) and an insensate salvage group (twenty-nine patients), the latter of which was the group of primary interest. In addition, a control group was constructed from the parent cohort so that the patients in the study groups could be compared with patients in whom plantar sensation was present and in whom the limb was reconstructed. Patient and injury characteristics as well as functional and health-related quality-of-life outcomes at twelve and twenty-four months after the injury were compared between the subjects in the insensate salvage group and those in the other two groups. RESULTS: The patients in the insensate salvage group did not report or demonstrate significantly worse outcomes at twelve or twenty-four months after the injury compared with subjects in the insensate amputation or sensate control groups. Among the patients in whom the limb was salvaged (that is, those in the insensate salvage and sensate control groups), an equal proportion (approximately 55%) had normal plantar sensation at two years after the injury, regardless of whether plantar sensation had been reported to be intact at the time of admission. No significant differences were noted among the three groups with regard to the overall, physical, or psychosocial scores. At two years after the injury, only one patient in the insensate salvage group had absent plantar sensation. CONCLUSIONS: Outcome was not adversely affected by limb salvage, despite the presence of an insensate foot at the time of presentation. More than one-half of the patients who had presented with an insensate foot that was treated with limb reconstruction ultimately regained sensation at two years. Initial plantar sensation is not prognostic of long-term plantar sensory status or functional outcomes and should not be a component of a limb-salvage decision algorithm.

Traumatic arterial injuries of the extremities: initial evaluation with MDCT angiography.

OBJECTIVE: The purpose of this study was to retrospectively assess the accuracy of MDCT angiography as the initial diagnostic technique to depict arterial injury in patients with extremity trauma. MATERIALS AND METHODS: Over 36 months, 87 patients (16 females and 71 males; age range, 16-87 years) with clinically suspected arterial injury after extremity trauma underwent 4-MDCT angiography and 67 ultimately underwent surgery. Eighty patients had blunt injuries, and seven had penetrating injuries. The presence of arterial involvement was investigated prospectively by the radiologist in charge and retrospectively by two independent radiologists. Each detected arterial lesion was then characterized as a spasm, stenosis, occlusion, or rupture. The standard of reference was surgery in 67 patients, angiography in two patients, and clinical and radiologic follow-up findings in 18 patients. MDCT angiography was assessed by means of receiver operating characteristic (ROC) curve analysis for lesion detection and Spearman's rank correlation test for lesion characterization. Image quality, lesion depiction, and artifacts were subjectively assessed. RESULTS: Sixty-two traumatic arterial lesions were confirmed at surgery in 55 patients. MDCT angiography yielded high accuracy in detection (area under the ROC curve [Az] = 0.96; p < 0.001) and characterization (r = 0.94; p < 0.001) of traumatic arterial injuries and in recognizing an underlying dissection (Az= 0.82; p < 0.001). Prospective sensitivity and specificity were 95% and 87%, respectively, and retrospective sensitivity and specificity were 99% and 87%, respectively. MDCT angiography was considered to be sufficient for a reliable diagnosis in 83 patients (p < 0.001). Image quality and lesion depiction on MDCT angiograms were considered to be good and artifacts were considered mild with substantial interobserver agreement (kappa, 0.62-0.69). CONCLUSION: MDCT angiography provides significant and reproducible technique for the detection and characterization of arterial injuries to the extremities with high image quality and vascular delineation.

Osseous change adjacent to soft-tissue hemangiomas of the extremities: correlation with lesion size and proximity to bone.

OBJECTIVE: The purpose of this study was to describe the findings of MR imaging and radiographic changes that occur in osseous structures adjacent to soft-tissue hemangiomas of the extremities and to correlate them with patient symptomatology, the size of the hemangiomas, and their proximity to adjacent bone. MATERIALS AND METHODS: We retrospectively reviewed the radiographs and MR images of 35 patients with soft-tissue hemangiomas of the extremities. The pattern and extent of the osseous change were categorized as periosteal, cortical, or medullary. Symptomatology, size, and proximity of the hemangioma to the adjacent bone were compared with the presence or absence of osseous change. Statistical analysis was performed using the Student's t test. RESULTS: Osseous change was noted on radiographs in 13 (37%) of 35 patients and on MR images in 11 (31%) of 35 patients with a total of 14 patients (40%) showing osseous change on at least one study. Periosteal change was present in eight (23%) of 35 patients; cortical change, in 11 (31%) of 35 patients; and medullary change, in 10 (29%) of 35 patients. Direct contact between the soft-tissue hemangioma and the adjacent bone was seen in 13 of 14 patients with osseous change. In those patients without osseous change, the average distance between the soft-tissue hemangioma and bone was 1.06 cm (range, 0-4 cm). No correlation was found between symptoms and the presence of osseous change. CONCLUSION: Soft-tissue hemangiomas of the extremities frequently result in adjacent osseous change that can be categorized as either periosteal, cortical, or medullary. Only medullary changes correspond with hemangioma size, whereas all three categories of change correlate with the proximity of the hemangioma to the adjacent bone. The presence of osseous change does not correlate with patient symptomatology.

MDCT compared with digital subtraction angiography for assessment of lower extremity arterial occlusive disease: importance of reviewing cross-sectional images.

OBJECTIVE: The aim of our study was to evaluate the efficacy of MDCT angiography in the assessment of lower limb peripheral arterial occlusive disease. MATERIALS AND METHODS: Twenty-four patients (representing 27 cases) with symptomatic lower extremity peripheral arterial occlusive disease underwent both MDCT angiography and digital subtraction angiography of the aortoiliac and lower extremity arteries. For data analysis, the arterial system was divided into 10 segments. Each segment was classified as normal, mildly stenotic, moderately stenotic, severely stenotic, or occluded. In evaluating MDCT angiographic findings, cross-sectional images were mainly observed by scrolling. The diagnostic accuracy of MDCT angiography was determined, using digital subtraction angiography as the standard reference. The extent of calcification in each segment was also assessed on MDCT angiography and was classified as absent, mildly calcified, or severely calcified. RESULTS: Of the 480 segments studied, 470 were assessable on both digital subtraction angiography and MDCT angiography. On digital subtraction angiography, 142 stenoocclusive segments (20 mildly stenotic, 14 moderately stenotic, 25 severely stenotic, and 83 occluded) were detected. With regard to the detection of segments that had more than mild stenosis, the sensitivity, specificity, and accuracy of MDCT angiography were 99.2%, 99.1%, and 99.1%, respectively. In the 421 noncalcified and mildly calcified segments, the sensitivity, specificity, and accuracy of MDCT angiography for the detection of more-than-mild stenosis were 100%, 100%, and 100%, respectively. CONCLUSION: MDCT angiography is a reliable method for evaluating the aortoiliac and lower extremity arteries.

The use of botulinum toxin therapy for lower-extremity spasticity in children with cerebral palsy.

Hypertonicity is a leading cause of disability for children with cerebral palsy (CP). Botulinum toxin A (BTA) chemically denervates muscle tissue and is commonly used in the management of lower-extremity hypertonicity in children with CP because of its focal effects and wide safety margin. Randomized controlled trials have demonstrated that BTA injections in the ankle flexors, hamstrings, and adductors reduce spasticity and result in improved passive and active range of motion. In other studies, improvements in gait and measurements of functional outcome were found in appropriately selected children who had been injected with BTA. A multidisciplinary treatment approach that includes physical therapists, occupational therapists, orthotists, neurologists, physicians with expertise in performing botulinum toxin injections, orthopedic surgeons, and neurosurgeons is critical to optimize care in children with lower-extremity tone due to CP. In this paper, the authors propose treatment algorithms based on clinical presentation, detailed dosing, and technical information to optimize the treatment of these children. With a multidisciplinary approach, children with lower-extremity hypertonicity due to CP can experience improvements in muscle tone and function.

[Effects of a tilting training program on lower extremities function, depression, and self-efficacy among stroke inpatients].

PURPOSE: The purpose of this study was to identify effects of a tilting training program on lower extremities function, depression, and self-efficacy among stroke inpatients. METHOD: The subjects were 60 stroke patients hospitalized in an oriental medical hospital; 31 in the experimental group and 29 in the control group. A nonequivalent control group pretest-posttest design was used. The tilting training program consisted of 3 sessions and was implemented for 30 minutes daily during 3 weeks. Data was collected from Feb to July 2003, and analyzed by percentage, Fisher's exact probability, chi2-test, and t-test using the SPSS/Win 10.0 computerized program. RESULT: After treatment with the tilting training program, the experimental group was significantly increased in the mean score for function of lower extremities (t=2.72, p=.009) compared to the control group, especially for keeping standing balance (t=2.78, p=.007) and standing by oneself (t=3.32, p=.002). However, in the mean scores of depression and self-efficacy, there were no significant differences between the two groups. CONCLUSION: The tilting training program was effective for increasing the function of lower extremities and to improve walking ability earlier among stroke inpatients. Therefore, the tilting training program is applicable to increase the balance level in standing and walking ability at the early rehabilitation stage for stroke patients.

Neoadjuvant chemotherapy and local radiotherapy for high-grade osteosarcoma of the extremities.

OBJECTIVE: To determine the effectiveness of radiation therapy for local control of nonmetastatic osteosarcoma of the extremities after induction chemotherapy. PATIENTS AND METHODS: Of 187 patients with nonmetastatic osteosarcoma of the extremities treated with induction chemotherapy since 1986, 31 refused surgery and underwent standard, fractionated external beam radiotherapy for local control. The median radiation dose to the limb was 60 Gy (range 40-68 Gy). Records were reviewed through April 2002, and outcomes including radiologic and biochemical response, local control, limb function, and survival were analyzed. The end points were local progression-free survival, metastases-free survival, and overall survival. RESULTS: Overall survival, local progression-free survival, and metastases-free survival at 5 years were a mean +/- SD of 61%+/-11%, 56%+/-12%, and 62%+/-10%, respectively. The outcome correlated significantly with patients' imaging and biochemical response. In patients who had a pronounced response, overall survival and metastases-free survival at 5 years were 90%+/-9% and 91%+/-9%, respectively, but it was only 35%+/-15% and 42%+/-13% in the nonresponders (P=.005 and P=.005, respectively). Local control was also related to response after induction chemotherapy. None of the 11 patients with both a good imaging and a good biochemical response had local relapse; median follow-up was 67 months. The estimated local progression-free survival among nonresponders was 31%+/-16% at 3 years and 0% at 5 years. Of 22 patients surviving without local disease progression, 19 (86%) had excellent limb function (Enneking score between 90% and 100%) at the time of most recent evaluation. CONCLUSION: When used after effective induction chemotherapy for osteosarcoma of the extremities, radiation therapy can be a reliable modality to control local disease and preserve limb function.

Standard wound coverage techniques for extremity war injury.

Reconstruction of extremity war injuries begins with aggressive forward resuscitative care and stabilization of the trauma patient. After serial care in progressively better supported medical environments, definitive management is done at the level V military treatment facility. Aggressive forward care coupled with rapid air transport has enabled increasingly complex care to be administered at the continental United States military facilities; however, it has also made the decision between limb salvage and amputation more challenging. Yet to be determined are (1) the optimal timing of definitive wound closure or coverage in coordination with fracture stabilization and (2) the optimal types of flap for both upper and lower extremity reconstruction. Records of patients with complex lower and upper extremity wounds who were treated at the National Naval Medical Center between September 2004 and June 2006 reveal useful short-term data. Longer-term data, such as fracture union rate, time to ambulation, range of motion and global function of salvaged limbs, patient satisfaction with limb salvage, and average cost, are not yet available.

Estimation of stature from upper extremity.

With the increasing frequency of mass disasters, identification of an isolated upper extremity and determination of the stature of the person it belonged to have created problems for investigation of the identity of some victims. Despite a need for such a study, there is a lack of systematic studies to identify fragmented and dismembered human remains. The purpose of this study was to analyze anthropometric relationships between dimensions of the upper extremity and body height. Analyses were based on a sample of middle class male (n = 202) and female (n = 108) Turks residing in Istanbul, Turkey. Five variables were entered into the analyses. For male subjects, forearm length was selected as the first factor, followed by hand length and finally upper arm length. For female subjects, upper arm length was selected first, followed by forearm length and finally hand length. There were also individually calculated formulae for some of these measurements that provided smaller R2 values. The study suggested that estimation of a living height could be made possible by using various dimensions of the upper extremity. One must consider differences between populations to apply such functions to other populations.
