Retrograde nailing of the femur using an intercondylar approach.

The standard of care for femoral fractures is an intramedullary nail, placed in an antegrade approach. This has produced high rates of healing and low complication rates. The use of retrograde nailing for femoral shaft fractures is a relatively new technique, previously described as an extraarticular approach. Forty-one patients with 45 fractures were available for assessment after retrograde femoral nailing using an intracondylar approach. There were 2 nonunions, which healed with revision surgery, in addition to 5 other complications including: reflex sympathetic dystrophy, an ileus, deep vein thrombosis, skin loss about the knee, and malrotation noted after initial nailing. There were no postoperative infections, no arthrosis was noted, and flexion of the knee averaged 129 degrees. Retrograde femoral nailing may be used to treat fractures in patients who present with multisystem trauma; multiskeletal trauma, especially peritrochanteric and acetabular injuries; floating knee fractures; bilateral femur fractures; and patients with morbid obesity.

Operative hip arthroscopy.

Twenty patients underwent operative arthroscopic procedures of the hip joint. All procedures were performed with the patient in the supine position on a standard fracture table using fluoroscopy through three arthroscopic portals (anterolateral, anterior paratrochanteric, and posterior paratrochanteric). The initial indications were therapeutic in 16 patients: loose bodies in four, synovial chondromatosis in three, rheumatoid arthritis in five, ankylosing spondylitis in one, septic arthritis in one, avascular necrosis of femoral head in one, and primary osteoarthritis in one. In four patients who had unexplained hip pain, the initial indications were diagnostic: minimal synovial change was seen in two patients, a synovial chondromatosis was present in another, and a tear of the acetabular labrum and hypertrophy of ligament teres were present in a fourth patient. In one patient who had primary osteoarthritis, the insertion of the arthroscopic instrument into the hip joint failed because of profuse osteophytes along the acetabular rim. Twelve of the 19 patients showed significant improvement of the symptoms after the arthroscopic procedure, but seven patients had no benefit from the procedure. One patient had a postoperative reflex sympathetic dystrophy.

External minifixation for treatment of closed fractures of the metacarpal bones.

External minifixators were used in the treatment of 63 closed diaphyseal metacarpal bone fractures. A simple half-frame configuration was applied in all the cases. Open reduction was performed in 26%. The mean duration of external fixation was 30 days. There were no cases of nonunion. Anatomical reduction was obtained in 86.6% of the cases. There were no cases of reflex sympathetic dystrophy. The general functional results were very good or good in 96.6%. Open reduction did not significantly alter the final results. External minifixation is usually accepted as a treatment of open metacarpal fractures. Because of the excellent results obtained in our series, we believe that the indications of external minifixation could be enlarged to closed metacarpal bone fractures.

Morbidity after crush injuries to the foot.

By retrospective review of hospital records and by follow-up clinical examinations, we evaluated 58 patients with crush injuries to the foot treated at our institution between 1986 and 1990. All patients had received initial treatment according to a standardized protocol determined by the type and magnitude of the injury. Patients were examined at a mean interval of 3.3 years (range 2-4) after injury, and the functional outcome was determined according to a foot trauma rating scale. Based on this scoring system, 46% of the patients had good functional outcome, 29% had fair results, and 25% had poor results. There was a significant correlation between a good functional outcome and careful adherence to the treatment protocol; however, some patients fared poorly regardless of treatment. Poor results occurred if treatment was not immediately initiated, if soft-tissue coverage was delayed (in those who experienced severe, mangling-type injuries necessitating partial foot amputation), if patients subsequently had neuritis or reflex sympathetic dystrophy, or if patients were involved in ongoing workers' compensation and litigation. We conclude that because crush injuries of the foot may be associated with prolonged morbidity, initial management should be directed toward recognition and treatment of compartment syndromes, early soft-tissue coverage, and rigid skeletal stabilization to enhance soft-tissue healing.

High-velocity gunshot wounds of the tibial plafond managed with Ilizarov external fixation: a report of 13 cases.

OBJECTIVE: To report the results of using Ilizarov fixation for the treatment of open tibial plafond fractures caused by high-velocity gunshot injuries. DESIGN Retrospective review of consecutive patients. SETTING: Military academic hospital. PATIENTS: Using the AO classification, three type C1, five type C2, and five type C3 open tibial plafond fractures due to high-velocity gunshot injuries were treated with irrigation, débridement, primary closure, and Ilizarov fixation. Eleven of the fractures were type IIIA, and the remaining two were type IIIB according to the Gustilo-Anderson classification. There were also multiple traumas in one case. METHODS: Plafond fractures were treated by Ilizarov technique in all 13 cases. In three of the cases, additional osseous transport to eliminate a skeletal defect was performed. MAIN OUTCOME MEASURES: Results were evaluated according to Bone's clinical grading system. RESULTS: Average follow-up was 38.4 months (range 26 to 50 months). Callus began to form in 21 to 35 days (average 27.9 days). The fractures united in 126 to 154 days (average 137.6 days), and the apparatus was removed from the limb at that time. There were six good, three fair, and four poor results. Minimal skin necrosis around the wound was seen in four cases, wound infection and purulent discharge were seen in two cases, and angular deformity was seen in two cases. Delayed union and reflex sympathetic dystrophy were not seen in any cases. Although tibiotalar narrowing was seen in four cases, no cases required tibiotalar arthrodesis or subsequent bony reconstruction at the time of their most recent follow-up. The average residual ankle range of motion was plantar flexion 18.5 degrees and dorsiflexion 11.5 degrees. CONCLUSIONS: Early aggressive débridement of nonviable tissues, stabilization with an Ilizarov external fixator, and either primary or delayed primary closure followed by early ankle range of motion and weight bearing is an alternative treatment method of these injuries.

Long-term results of the external fixation of distal radius fractures.

OBJECTIVE: To evaluate the long-term results of external fixation of distal radius fractures. METHODS: A retrospective follow-up study (median follow-up, 5.3 years) of 49 patients with 50 distal radius fractures treated with an external fixator was carried out. An external fixator (Minifixator, Stratec Medical, Waldenburg, Switzerland) was used. The operative procedure is described in detail. A personal evaluation including clinical and radiologic assessment of both wrists was performed. RESULTS: The functional results, including the parameters strength, daily activities, range of motion, and presence of pain, as well as an anatomic score, the presence of osteoarthritis, the quality of reduction, and complications were recorded. Functional and anatomic results indicated excellent to good ratings in more than 80% of the cases. CONCLUSION: The external fixator is a versatile tool in the treatment of intra-articular and extra-articular fractures of the distal radius. The rate of algodystrophy (reflex sympathetic dystrophy) was 6%, and wrist stiffness was not found in our series.

Foot and ankle problems in the young athlete.

In the U.S., greater than half of boys and one quarter of girls in the 8- to 16-yr-old age range are engaged in some type of competitive, scholastic, organized sport during the school year. Children and adolescents are becoming more involved in sports at earlier ages and with higher levels of intensity. Foot and ankle problems, in particular, are the second most common musculoskeletal problem facing primary care physicians in children under 10 yr of age next to acute injury. This report focuses on foot and ankle problems, trauma, and overuse in the young athletic population. Guidelines are given for both conservative and surgical management. Specific problems addressed include pes planus, tarsal coalition, adolescent bunion, os trigonum, accessory navicular, physeal fractures, sprains, peroneal tendon subluxation, metatarsal fractures, sesamoid fractures, turf toe, stress fractures, tendonitis, osteochondritis dissecans, ankle impingement, bursitis, Haglund's deformity, sesamoiditis, plantar fasciitis, apophysitis, osteochondroses, cuboid syndrome, and reflex sympathetic dystrophy. An extensive review of the literature is performed and presented in combination with the extensive experience of a well-established sports medicine clinic at the Boston Children's Hospital.

A man for all seasons: W.W. Keen.

William Williams Keen was the catalyst for the advent of neurosurgery in the United States. He served in the Civil War and collaborated with Silas Weir Mitchell in studying injuries sustained to the nervous system. These studies culminated in the publication in 1864 of "Gunshot Wounds and Other Injuries of the Nerves and Reflex Paralysis," which first described causalgia, reflex sympathetic dystrophy, and secondary paralysis. His most monumental accomplishment undoubtedly was being the first surgeon in the United States to successfully remove a primary brain tumor (1887) and have the patient survive for more than 30 years. As the editor of "Surgery, Its Principles and Practice," Keen invited Harvey Cushing to write the section on surgery of the head, which propelled Cushing to international recognition and provided a foothold for the new specialty of neurosurgery. Multiple sources were reviewed to prepare this comprehensive biographical account of Keen's contributions. Emphasis is placed on those achievements that furthered the discipline of neurosurgery. Although a general surgeon, Keen had a special interest in the nervous system. He treated patients with trigeminal neuralgia, performed cortical excisions for patients with epilepsy, and devised the procedure of posterior upper cervical root sections for spasmodic torticollis. He was the first surgeon to perform and advocate ventricular punctures. He served as a consultant and surgeon to both Grover Cleveland and Franklin Delano Roosevelt.

Vulvodynia: diagnostic techniques and treatment modalities.

Vulvodynia is a chronic vulvar discomfort often characterized by the patient's complaint of burning, stinging, irritation, or rawness. Vulvodynia has been recorded for centuries. Successful diagnostic techniques and treatment modalities, however, have come about only in the last decade. An accurate diagnosis is based on an exhaustive history and detailed physical examination. Highly technical and costly diagnostics provide little supplemental information. Differential diagnosis, previously called subsets of vulvodynia, includes infections (Candida, human papillomavirus, and herpes simplex virus), dermatoses (lichen sclerosus and inflammatory dermatoses), vulvar vestibulitis, iatrogenic causes, and dysesthesias (pudendal neuralgia and reflex sympathetic dystrophy). Primary care providers are fully capable of accurately diagnosing and managing vulvodynia patients, relying on subspecialty referral only for surgical intervention in selected cases.

Common athletic injuries in adolescent girls.

Teenaged girls constitute the fastest growing segment of children and adolescents participating in organized athletics. Adolescent girls appear to have similar injury rates as boys in comparable activities but different injury patterns. To properly diagnose and manage athletic injuries in adolescent girls, pediatric health care providers must be aware of these differences, especially as the literature and their knowledge base may be skewed to the traditional predominance of males in sport. This review identifies athletic injuries that are unique to or especially common in adolescent girls, including apophyseal injuries; breast and pelvic injuries; scoliosis and spondylolysis; multidirectional shoulder instability and "gymnast's wrist"; anterior cruciate ligament injuries and patellofemoral pain syndrome; chronic exertional lower-leg compartment syndrome, ankle sprains, and reflex sympathetic dystrophy; and stress fractures. It also briefly discusses possible risk factors for these injuries, emphasizing the female athlete triad.

Effectiveness of spinal cord stimulation in the management of chronic pain: analysis of technical drawbacks and solutions.

OBJECTIVE: A major drawback of currently available spinal cord stimulation (SCS) systems for the management of chronic intractable pain, especially of widespread pain patterns as in reflex sympathetic dystrophy, is the generally limited paresthesia coverage. The aim of this study is to analyze the origin of this problem and to provide solutions. METHODS: Results from theoretical studies, in which a computer model was used to mimic the effects of SCS on spinal nerve fibers, were used to analyze which factors may limit paresthesia coverage. Model predictions were verified by empirical data from clinical literature. RESULTS: When using common SCS electrodes, both perception threshold and motor/discomfort threshold are generally related to dorsal root stimulation. Because these thresholds have a small ratio (approximately 1:1.4), stimulation of dorsal column fibers and paresthesia coverage is limited by this small range of stimulation. When the distance between the epidural electrode and spinal cord is large (midthoracically), the threshold for dorsal column stimulation exceeds discomfort threshold, resulting only in segmental paresthesia. The range of dorsal column stimulation and paresthesia coverage can be improved when using either an optimally dimensioned rostrocaudal bi-/tripole or a transverse tripole ("guarded cathode"). When applying the latter in combination with a dual channel pulse generator providing simultaneous pulses, paresthesias can simply be changed to optimally cover the painful area. CONCLUSION: Paresthesia coverage and pain management by SCS can be improved when using electrodes as proposed.

Diagnosis of complex regional pain syndrome: signs, symptoms, and new empirically derived diagnostic criteria.

This review will discuss the relevant history of the taxonomy and eventual development of diagnostic criteria of what is currently called complex regional pain syndrome. The authors will take their discussion through the early days (at which time the disorder was called reflex sympathetic dystrophy) through consensus-developing conferences to the current conceptualization of the criteria as published by the International Association for the Study of Pain's Task Force on Taxonomy in 1994. The authors will also mention the recent work of the closed workshop held in Budapest in 2004, where clinical and research criteria were proposed; these criteria were published in 2005. The review will also address issues of staging and subtyping the syndrome, as well as a discussion of the salient signs, symptoms, and tests appropriate for use in the diagnosis.

Extended medial gastrocnemius rotational flap for treatment of chronic knee extensor mechanism deficiency in patients with and without total knee arthroplasty.

Nine patients with chronic extensor mechanism disruption were treated with an extended medial gastrocnemius rotational flap reconstruction of the extensor mechanism. Seven patients previously had total knee arthroplasty and two patients had chronic infection of nonreplaced, native knees. Four patients previously had failed Achilles' tendon allograft reconstruction after total knee arthroplasty and two were complicated by infection. Infected arthroplasty patients had a staged procedure with placement of an antibiotic spacer after debridement and extended medial gastrocnemius rotational flap, followed by total knee arthroplasty replant 8 weeks later. The four infected arthroplasty patients had medical comorbidities that included a patient with HIV and hemophilia, and two with diabetes mellitus. Another patient with rheumatoid arthritis was severely malnourished as a result of dumping syndrome. Of the four patients treated by this two-stage procedure, one died in the early postoperative period from chronic medical issues after the second stage and another patient elected to have above-knee amputation after the first stage because of severe reflex sympathetic dystrophy. The final group of seven patients was studied at a mean followup of 21 months (range, 7-31 months), the average extensor lag was 13.5 degrees (range, 0-50 degrees ), and the average range of motion was 2 degrees to 93 degrees . The two patients with nonreplaced, native knees had extensor lags of 30 degrees and 10 degrees . All patients were able to regain sufficient extensor mechanism strength to return to independent ambulation, and all infections resolved after treatment. Two patients were able to ascend stairs foot over foot without support. In addition to the patient who had amputation, the other complication involved a wound breakdown that required a free flap at 13 months in a patient who had a failed Achilles' tendon allograft reconstruction after takedown of a knee fusion. Medial gastrocnemius flap reconstruction can provide successful salvage of a failed extensor mechanism allograft or an alternative to allograft reconstruction in patients with poor soft tissue coverage, previous infection, or a compromised immune system.

Curved periacetabular osteotomy for treatment of dysplastic hip.

UNLABELLED: The Bernese periacetabular osteotomy has a considerable rate of postoperative complications such as reflex sympathetic dystrophy, motor nerve palsy, heterotopic ossification, and delayed union of the ilium, which are assumed to be caused by extensive exposure or asphericity of the osteotomy surfaces. To address these issues, we developed the curved periacetabular osteotomy, a modification of the Bernese periacetabular osteotomy which limits dissection, prevents the outside of the ilium from being exposed, and produces osteotomy surfaces with the same curvature. Curved periacetabular osteotomies were done on 128 hips in 118 patients whose average age at the time of surgery was 35.2 years (range, 16-59 years). The average followup was 46 months (range, 24-99 months). The average center-edge angles were 4 degrees (range, -15 degrees -5 degrees ) preoperatively and 35 degrees (20 degrees -55 degrees ) postoperatively, and union of the iliac osteotomy was achieved in all hips. We experienced three asymptomatic pubic nonunions. Dysesthesias occurred in 27 patients along the lateral femoral cutaneous nerve and symptoms resolved in 23 patients within 1 year. The average Harris hip score improved from 72 to 93 points. There were no major complications such as sciatic nerve palsy, abductor dysfunction, or heterotopic ossification. LEVEL OF EVIDENCE: Therapeutic study, Level IV (case series--no, or historical control group). See the Guidelines for Authors for a complete description of levels of evidence.

Diagnosis of spinal disease with ultrafine flexible fiberscopes in patients with chronic pain.

STUDY DESIGN: Spinal epidural and subarachnoid spaces were observed with the newly developed fine flexible fiberscopes in 55 patients with chronic pain. OBJECTIVES: To evaluate the fiberscopes as diagnostic tools for spinal canal disease. SUMMARY OF BACKGROUND DATA: Fine flexible fiberscopes make it possible to visualize the entire length of the spinal subarachnoid space without major complications, and they may be of value for the diagnosis of certain spinal canal diseases. METHODS: The epidural and subarachnoid spaces were accessed by fine flexible fiberscopes (Purely Fine [PF] types) in the initial 45 patients and by those equipped with a tip-steering function and a working channel (Medical Science [MS] types) in the later 10 patients, respectively. The procedures were based on those of continuous epidural or subarachnoid block. RESULTS: Normal and abnormal subarachnoid spaces were clearly observed. When the MS types were used, the intended sites of the spinal structures could be more easily approached. In 12 patients, new diagnoses were made (chronic arachnoiditis 9, subarachnoid cyst 2, old subdural hematoma 1) that could not be found by magnetic resonance imaging or computed tomography. Additionally, chronic arachnoiditis was found in 2 patients with spinal trauma. Pathologic changes were confirmed by fiberscopic examination in 16 patients (arachnoiditis 11, spinal trauma 2, arteriovenous malformation 2, subarachnoid cyst 1). No pathologic changes could be detected in 27 patients with spinal canal stenosis, disc herniation, reflex sympathetic dystrophy, or posttraumatic pain syndrome. There were no significant differences in incidence of new diagnoses between the PF and MS types of fiberscopes. There were no major complications. There were 2 cases of light fever in the initial 10 patients and 7 cases of headache in the initial 14 patients. Only 4 cases of headache were observed in the subsequent 41 patients, in whom 20 mL of saline was injected into the epidural space. CONCLUSION: These fine flexible fiberscopes may provide new diagnostic and interventional tools for spinal canal diseases, provided skilled techniques are applied.

Treatment of unstable extra-articular distal radius fractures by modified intrafocal Kapandji method.

The authors prospectively assess the results of surgically treated, unstable extra-articular distal radius fractures from 29 patients with good bone quality. Mean age was 49 years, ranging from 22 to 69 years; the female gender was the most frequently affected (58.6% of the cases). Surgical fixation was indicated for fractures presenting an angulation above 20 degrees , marked dorsal comminution, and radius shortening in excess of 10 mm on initial x-rays (anteroposterior and lateral views). The Kapandji technique, with intrafocal, nonthreaded Kirschner wires, was employed. Clinical data assessed anatomic aspects according to Scheck, functional aspect after Gartland and Werley, strength by Scheck's methods, and esthetic by Frykman's criteria. Functional assessment, according to Gartland and Werley, revealed 72.1% of excellent and good results at 3 months; 89.7% at 6 months; and 96.6% at 12 months. Immediate postoperative reduction was not maintained at the final follow-up at 12 months; however, that loss was not severe, and the anatomic outcome was good and excellent in 96.6% of the cases. Six patients presented complications. Four patients presented reflex sympathetic dystrophy; 1 patient had a superficial Kirschner wire infection, and another patient had radial nerve superficial branch paresthesia. The employed technique showed to be effective in the treatment of unstable, extra-articular fractures of the distal radius. It is easy to learn and to perform. The device employed has a low cost and is widely available in operation rooms.

Outcome of open release for post-traumatic elbow stiffness.

BACKGROUND: Post-traumatic elbow stiffness can be caused by a tether and/or a block, and these structures can exist both anteriorly and posteriorly about the joint to prevent motion. The purpose of this article is to report the outcome of elbow release performed for post-traumatic stiffness by a single surgeon. METHODS: A retrospective review of charts and radiographs was performed on 52 case of patients who underwent open surgical treatment for post-traumatic elbow contracture by the senior author (RHN). The mean age of the group was 35.1 years. There were 32 men and 20 women. Contracture release surgery was performed at an average of 14 months from the time of injury. Indication for operative release was functional loss of elbow arc of motion that failed nonoperative therapy and splinting program. Follow-up was 18.7 months. Comparison of ranges of motion was performed with Student's paired t tests. RESULTS: The average extension-flexion arc of motion improved from 57 to 116 degrees and forearm rotation improved from 119 to 145 degrees postoperatively. Fourteen patients (27%) required closed manipulation under anesthesia, in the early postoperative period. Five patients required a second contracture release at an average of 12 months after the index release. Four patients failed because of painful motion (n = 2) and elbow instability (n = 2). Other complications included wound infection (n = 3), cubital tunnel syndrome (n = 3) and reflex sympathetic dystrophy (n = 1). CONCLUSIONS: Open elbow release with excision of tethers and blocks is a valuable procedure for post-traumatic stiffness. Recurrence in postoperative period is common but is responsive to manipulation under anesthesia and repeat releases.

Pediatric orthopedic pain of unknown origin.

Thirty-eight cases of musculoskeletal pain in a pediatric population that defied diagnosis are reviewed. The time between the onset of symptoms and the final diagnosis averaged 11.4 months, but in many cases was greater than 1 year. The most common diagnoses included reflex sympathetic dystrophy, osteoid osteoma, osteomyelitis, intraarticular hemangiomata, slipped epiphyses, and rheumatoid variants. There were several uncommon causes of pain, such as soft tissue hemangiomata, dystonia, and Addison disease. The pitfalls and causes of error are reviewed.
