Therapeutic advances in ankylosing spondylitis.

Ankylosing spondylitis (AS) is a systemic inflammatory rheumatic disease involving spinal and sacroiliac joints. This condition is responsible for back pain, stiffness, but also loss of functional capacity with socio-economic consequences. The management of AS includes patient education, rest, a programme of regular physical exercise, together with the use of NSAIDs. Second-line treatments are required in cases of severe or refractory AS, however only sulfasalazine has proven to benefit AS patients with peripheral arthritis. In spite of this management, the disease may not be adequately controlled, mainly for patients with refractory axial disease, enthesopathy or extra-articular features. Thus, new innovative treatments are needed for AS. It is likely that the new NSAIDs or COX-2 specific inhibitors will certainly take the place of the conventional NSAIDs, with regard to their superior tolerability. Methotrexate is a therapeutic option for AS treatment, but its usefulness in this disease remains to be established in adequate controlled studies. Finally, the TNF-alpha targeting drugs, namely thalidomide and the anti-TNF-alpha mAb, infliximab, have given promising results in the treatment of severe and/or refractory AS patients, however further controlled studies are required. In addition, the long-term use (efficacy and tolerability) of these two agents deserves attention.

Total knee arthroplasty in patients with ankylosing spondylitis.

BACKGROUND: Ankylosing spondylitis is a seronegative spondyloarthropathy that primarily affects the sacroiliac joints, spine, hips, and, less commonly, the knee joints. The purpose of this study was to evaluate the results in a consecutive group of patients with ankylosing spondylitis who underwent total knee arthroplasty. METHODS: The results of thirty total knee arthroplasties in twenty patients with ankylosing spondylitis were reviewed. There were seventeen men and three women, with an average age of fifty-five years (range, twenty-eight to sixty-seven years) at the time of the arthroplasty. The diagnosis of ankylosing spondylitis was established preoperatively with use of the New York criteria. All patients received a cemented condylar-type implant. The average duration of follow-up was 11.2 years (range, three to sixteen years). RESULTS: The average Knee Society pain score improved from 14 points preoperatively to 76.3 points at the time of the latest follow-up. The improvement in the average Knee Society function score was less impressive, with an increase from 16.3 points preoperatively to 58.7 points at the time of the latest follow-up. The average arc of motion was 84.8 degrees prior to the arthroplasty and 86.7 degrees at the time of the final follow-up. Six knees (20%) had heterotopic bone formation. Three knees required manipulation under anesthesia because of poor motion postoperatively. There was one revision, due to loosening of a patellar component. All other components were radiographically stable at the time of the latest follow-up. CONCLUSIONS: Total knee arthroplasty with cement in patients with ankylosing spondylitis provided excellent pain relief and durable fixation at an average of 11.2 years postoperatively. However, patients with ankylosing spondylitis are at increased risk for the development of stiffness and heterotopic bone formation.

Clinical outcomes of unstable pelvic fractures in skeletally immature patients.

BACKGROUND: The orthopaedic literature contains few studies evaluating the long-term outcomes of unstable pelvic fractures in skeletally immature patients. The purpose of this study was to determine the factors that may influence the clinical and functional outcomes of such fractures. METHODS: A retrospective review of all patients with open triradiate cartilages and an unstable pelvic (Tile type-B or C) fracture treated, from 1986 to 2000, at one of two level-I trauma centers was performed. Patients were evaluated with a review of their medical records, the Modified Injury Severity Score (MISS), standardized physical examination, standardized radiographic evaluation, and the Short Musculoskeletal Function Assessment Questionnaire (SMFA). The outcomes were then used to assess the difference between patients who had been treated operatively and those who had been treated nonoperatively. RESULTS: Of 230 pelvic fractures treated during the study period, twenty-three in twenty-three patients were unstable. Of the twenty-three patients, twenty, with a mean age of 9.5 years at the time of injury, were evaluated. The mean duration of follow-up was 6.5 years. There were four type-B and sixteen type-C fractures according to the Tile classification system. The four patients with a type-B fracture had a mean of 1.4 cm of pelvic asymmetry at the time of union and the last follow-up, whereas the sixteen patients with a type-C fracture had a mean of 1.5 cm of pelvic asymmetry at those times. Pelvic asymmetry did not remodel even in younger patients. Eighteen patients were treated operatively with external fixation, internal fixation, or a combination of both, and pelvic asymmetry of < or =1 cm was achieved in ten of them. Patients who had < or =1 cm of pelvic asymmetry had no lumbar or sacroiliac pain, no or mild sacroiliac tenderness, no Trendelenburg sign, no lumbar scoliosis, and lower (better) bother and dysfunction scores on the SMFA compared with patients with more pelvic asymmetry. All patients with > or =1.1 cm of pelvic asymmetry had three or more of the following: nonstructural scoliosis, lumbar pain, a Trendelenburg sign, or sacroiliac joint tenderness and pain. Patients with fewer associated injuries and pelvic asymmetry of < or =1 cm had better clinical results. CONCLUSIONS: Unstable pelvic fractures in children can result in long-term morbidity and functional problems. Fractures associated with > or =1.1 cm of pelvic asymmetry following closed reduction should be treated with open reduction and internal or external fixation in order to improve alignment and the long-term functional outcome.

Low back pain in young athletes. A practical approach.

Lumbar spine pain accounts for 5 to 8% of athletic injuries. Although back pain is not the most common injury, it is one of the most challenging for the sports physician to diagnose and treat. Factors predisposing the young athlete to back injury include the growth spurt, abrupt increases in training intensity or frequency, improper technique, unsuitable sports equipment, and leg-length inequality. Poor strength of the back extensor and abdominal musculature, and inflexibility of the lumbar spine, hamstrings and hip flexor muscles may contribute to chronic low back pain. Excessive lifting and twisting may produce sprains and strains, the most common cause of low back pain in adolescents. Blows to the spine may create contusions or fractures. Fractures in adolescents from severe trauma include compression fracture, comminuted fracture, fracture of the growth plate at the vertebral end plate, lumbar transverse process fracture, and a fracture of the spinous process. Athletes who participate in sports involving repeated and forceful hyperextension of the spine may suffer from lumbar facet syndrome, spondylolysis, or spondylolisthesis. The large sacroiliac joint is also prone to irritation. The signs and symptoms of disc herniation in adolescents may be more subtle than in adults. Disorders simulating athletic injury include tumours and inflammatory connective tissue disease. Often, however, a specific diagnosis cannot be made in the young athlete with a low back injury due to the lack of pain localisation and the anatomic complexity of the lumbar spine. A thorough history and physical examination are usually more productive in determining a diagnosis and guiding treatment than imaging techniques. Diagnostic tests may be considered, though, for the adolescent athlete whose back pain is severe, was caused by acute trauma, or fails to improve with conservative therapy after several weeks. Radiographs, bone scanning, computed tomography, and magnetic resonance imaging may help identify, or exclude serious pathology. Fortunately, the majority of cases of low back pain in adolescents respond to conservative therapy. Immediate treatment of an acute injury, such as a sprain or strain, includes cryotherapy, electrogalvanic stimulation, anti-inflammatory medications and gentle exercises. Prolonged bed rest should be avoided since atrophy may occur rapidly. Strong analgesics are also usually contraindicated, except for sleep, since they mask pain and may allow overvigorous activity. Early strengthening exercises include the Williams flexion exercises and/or McKenzie extension exercises. Both exercise motions may often be prescribed. Athletes with an acute disc herniation, however, should only perform extension exercises initially. Athletes with spondylolysis, spondylolisthesis and facet joint irritation should initially be limited to flexion exercises.(ABSTRACT TRUNCATED AT 400 WORDS)

Rowing injuries.

Participation in the sport of rowing has been steadily increasing in recent decades, yet few studies address the specific injuries incurred. This article reviews the most common injuries described in the literature, including musculoskeletal problems in the lower back, ribs, shoulder, wrist and knee. A review of basic rowing physiology and equipment is included, along with a description of the mechanics of the rowing stroke. This information is necessary in order to make an accurate diagnosis and treatment protocol for these injuries, which are mainly chronic in nature. The most frequently injured region is the low back, mainly due to excessive hyperflexion and twisting, and can include specific injuries such as spondylolysis, sacroiliac joint dysfunction and disc herniation. Rib stress fractures account for the most time lost from on-water training and competition. Although theories abound for the mechanism of injury, the exact aetiology of rib stress fractures remains unknown. Other injuries discussed within, which are specific to ribs, include costochondritis, costovertebral joint subluxation and intercostal muscle strains. Shoulder pain is quite common in rowers and can be the result of overuse, poor technique, or tension in the upper body. Injuries concerning the forearm and wrist are also common, and can include exertional compartment syndrome, lateral epicondylitis, deQuervain's and intersection syndrome, and tenosynovitis of the wrist extensors. In the lower body, the major injuries reported include generalised patellofemoral pain due to abnormal patellar tracking, and iliotibial band friction syndrome. Lastly, dermatological issues, such as blisters and abrasions, and miscellaneous issues, such as environmental concerns and the female athlete triad, are also included in this article.Pathophysiology, mechanism of injury, assessment and management strategies are outlined in the text for each injury, with special attention given to ways to correct biomechanical or equipment problems specific to rowing. By gaining an understanding of basic rowing biomechanics and training habits, the physician and/or healthcare provider will be better equipped to treat and prevent injuries in the rowing population.

Radiographic features of ureteral endometriosis.

The urographic findings in seven patients with ureteral endometriosis were reviewed. These consisted of short strictures (0.5-2.2 cm) located for the most part in that portion of the pelvic ureter projected within 3 cm of the inferior margin of the sacroiliac joint. Although the appearance is judged to be nonspecific, the diagnosis of ureteral endometriosis should be considered in any female patient of child-bearing age who has obstructive uropathy attributable to extrinsic obstruction of the pelvic portion of the ureter.

Sternocostoclavicular hyperostosis in children: a report of eight cases.

OBJECTIVE: The aim of this paper is to clarify the clinical and radiologic features of sternocostoclavicular hyperostosis by reviewing eight previously unpublished cases in children, identifying its similarities to chronic recurrent multifocal osteomyelitis and the differences between the pediatric and adult population affected with sternocostoclavicular hyperostosis. Appropriate imaging workup will obviate unnecessary diagnostic and therapeutic procedures. MATERIALS AND METHODS: We investigated the clinical and imaging features of sternocostoclavicular hyperostosis in eight children (seven girls and one boy) and compared those features with the characteristic features of chronic recurrent multifocal osteomyelitis and sclerosing Garré's osteomyelitis to determine if sternocostoclavicular hyperostosis can justifiably be classified as a separate entity. All patients underwent one or more bone biopsies to determine the cause of the bone lesion(s). RESULTS: Seven of the eight patients had involvement of the clavicle. Five of the eight patients had associated distant involvement in the pelvis, femur, tibia, fibula, talus, or sacroiliac joints. Except for predominant localization in the anterior chest wall, the symptoms, the clinical and imaging features, and the results of biopsy and histopathologic examination resemble those of chronic recurrent nonspecific sclerosing osteomyelitis. No skin lesion and no causative organism was found in any of the cases. CONCLUSION: Sternocostoclavicular hyperostosis is a descriptive term used to designate a form of chronic sclerosing osteomyelitis. Its only distinctive feature is localization on one or more sites of the anterior chest wall.

Use of routine ventrodorsal radiographic views of the pelvis to assess inclination of the wings of the sacrum in dogs.

OBJECTIVE: To determine the ratio of ventral-to-dorsal transverse diameters between the wings of the sacrum on ventrodorsal radiographic views of the pelvis in large dogs and to validate the reliability of this morphometric analysis for functional interpretation. SAMPLE POPULATION: Pelvic specimens from 40 large-breed dogs and radiographs of 113 large-breed dogs. PROCEDURE: In an anatomic and radiographic evaluation, the transverse dorsal diameter (TVDS) and transverse ventral diameter (TVV) between the wings of the sacrum were evaluated in sacrum specimens and on corresponding radiographs of the pelvis and sacrum. The ratio between TVV and TVDS (VD ratio) was calculated. Intraobserver reliability was determined by calculation of the coefficient of variation. In a retrospective radiographic evaluation, the VD ratio was determined in Rottweilers, Golden Retrievers, and German Shepherd Dogs. Correlations between VD ratio and breed, age, and sex were tested. RESULTS: The VD ratio was significantly higher in Rottweilers than in Golden Retrievers and German Shepherd Dogs, denoting an oblique alignment of the sacral wings in Rottweilers (ie, the dorsal aspects of the sacral wings were located more medially than the ventral aspects) and an almost sagittal alignment in the other breeds. The VD ratio was significantly associated with age but not with sex. CONCLUSIONS AND CLINICAL RELEVANCE: Sagittal alignment of the wings of the sacrum is considered to be biomechanically less efficient. These results provide a basis for further studies to evaluate radiographic assessment of the sacroiliac joints similar to the evaluation for hip dysplasia.

A three-paradigm treatment model using soft tissue mobilization and guided movement-awareness techniques for a patient with chronic low back pain: a case study.

It is not uncommon for physical therapists to report difficulty in treating certain subjects with chronic idiopathic low back pain. The purpose of this case study is to present a three-paradigm model of intervention that may be adapted to the treatment of such cases. The model consists of: 1) relaxation paradigm, consisting of pain modulation procedures; 2) corrective paradigm, involving manual techniques and exercise to correct specific faulty biomechanical alignment(s) eg., pelvic asymmetry); and 3) integrative paradigm, utilizing guided movement/mobilization techniques for improving the subject's overall pattern of posture and movement. The case study of a young adult with chronic low back pain correlated with unilateral innominate bone rotation is presented to illustrate the three-paradigm approach. Over six sessions, the subject received a corrective (sessions 1-3) and an integrative treatment protocol (sessions 4-6) consisting of Rolf's method of soft tissue mobilization and Alexander's system of guided movement-awareness techniques. Before and after each session and after a 4-week follow-up, the subject was assessed for sacroiliac joint pain using a compression technique, anterior rotation of the innominate bones, pelvic angle in the standing position, and vagal tone as determined from heart rate variability. The therapist's visual analysis of sit-to-stand movement and the subject's self-reports of pain were noted. A corrective paradigm protocol of soft tissue mobilization and exercise was unsuccessful in eliminating the subject's assessed anterior rotation of the innominate bone and associated low back pain for more than 1-2 days posttreatment. Only after the implementation of a third paradigm movement/mobilization protocol did the subject begin to exhibit sustained improvement through a 4-week follow-up. Interpretations of the results, appropriate selection of corrective and integrative protocols, and physiological mechanisms are discussed.

A roentgen stereophotogrammetric investigation of innominate osteotomy (Salter).

The effect of the innominate osteotomy according to Salter was investigated by a roentgen stereophotogrammetric method in a 17-year-old girl with hip dysplasia as a part of the tricho-rhino-phalangeal (Giedion) syndrome. The osteotomy resulted in a total rotation of 32 degrees about an axis passing cranially to the pubic symphysis and the osteotomy. The acetabulum rotated 22 degrees forwards about a transverse axis, 9 degrees laterally about a longitudinal axis and 24 degrees laterally about a sagittal axis. The acetabulum was translated 2 mm laterally along a transverse axis, 21 mm caudally along a longitudinal axis and 19 mm dorsally along a sagittal axis. The position of the screw axis indicates that some motion also took place in one or both of the sacroiliac joints. The correction as measured with the CE-angle was 25 degrees which was almost the same as the correction about the sagittal axis. It is, however, noted that the CE-angle was also dependent upon the rotations about the transverse and longitudinal axes.

The role of HLA-B27 in the diagnosis of low back pain.

The HLA-B27 antigen was determined in 652 patients with low back pain which had lasted for more than 3 months. A clinical and roentgenological examination of the sacroiliac joints and the thoraco-lumbar spine was performed in all the patients. The control group consisted of 302 unrelated persons who did not show signs of low back pain. Antigen HLA-B27 was found in 276 of these 652 patients attending the ward for rheumatic diseases (42.4 per cent) and in 37 of the 302 unrelated persons in the control group (12.2 per cent). The difference is statistically highly significant (P less than 0.001). Ankylosing spondylitis was found in 128 out of the 276 patients with low back pain and antigen HLA-B27. This demonstrates the importance of this antigen in the differential diagnosis of low back pain.

Surgical management of giant sacral schwannomas.

Thirteen cases of giant sacral schwannomas with erosion of the anterior aspect of the sacrum and associated intrapelvic extension are reviewed. These tumors showed no sex predilection; the patients' mean age was 38.6 years at the time of diagnosis, and their symptoms predated the diagnosis by an average of 5.2 years. The most common symptoms were low-back pain and lower-extremity dysesthesiae. Plain roentgenograms, myelography, and computerized tomography constituted essential and complementary studies in the preoperative assessment. Choice of surgical approach (anterior transabdominal vs. posterior transsacral) was dependent upon the amount of sacral destruction, intrapelvic extension, and sacroiliac joint involvement. Microscopic examination revealed classic features of benign schwannoma in all but three cases, which were classified as cellular schwannomas. Patients who presented with pain and dysesthesiae reported immediate and complete relief of symptoms following surgery. In addition, all 13 patients were ambulatory and able to resume their routine daily activities postoperatively. At the last reported follow-up examination, which ranged from 5 months to 33 years and 3 months (mean 9 years) after surgery, two patients had died of unrelated causes, two reported return of preoperative symptoms, and the remainder were asymptomatic. This experience suggests that these histologically benign but neurologically devastating tumors should be aggressively resected with the intent of complete extirpation, and that this goal may be accomplished with minimal risk and an excellent prognosis.

Total sacrectomy and Galveston L-rod reconstruction for malignant neoplasms. Technical note.

Although radical resection is the best treatment for malignant sacral tumors, total sacrectomy for such tumors has been performed in only a few instances. Total sacral resection requires reconstruction of the pelvic ring plus establishment of a bilateral union between the lumbar spine and iliac bone. This technique is illustrated in two patients harboring large, painful, sacral giant-cell tumors that were unresponsive to prior treatment. These patients were treated with complete en bloc resection of the sacrum and complex iliolumbar reconstruction/stabilization and fusion. Surgery was performed in two stages, the first consisting of a midline celiotomy, dissection of visceral/neural structures, and ligation of internal iliac vessels, followed by an anterior L5-S1 discectomy. The second stage consisted of mobilization of an inferiorly based myocutaneous rectus abdominis pedicle flap for wound closure, followed by an L-5 laminectomy, bilateral L-5 foraminotomy, ligation of the thecal sac, division of sacral nerve roots, and transection of the ilia lateral to the tumor and sacroiliac joints. Placement of the instrumentation required segmental fixation of the lumbar spine from L-3 down by means of pedicle screws and the establishment of a bilateral liaison between the lumbar spine and the ilia by using the Galveston L-rod technique. The pelvic ring was then reestablished by means of a threaded rod connecting left and right ilia. Both autologous (posterior iliac crest) and allograft bone were used for fusion, and a tibial allograft strut was placed between the remaining ilia. The patients were immobilized for 8 weeks postoperatively and underwent progressive rehabilitation. At the 1-year follow-up review, one patient could walk unassisted, and the other ambulated independently using a cane. Both patients controlled bowel function satisfactorily with laxatives and diet and could maintain continence but required self-catheterization for bladder emptying. The authors conclude that in selected patients, total sacrectomy represents an acceptable surgical procedure that can offer not only effective local pain control, but also a potential cure, while preserving satisfactory ambulatory capacity and neurological function.

Local recurrence after S2-3 sacrectomy in sacral chordoma. Report of four cases.

Excision is the treatment of choice in cases of sacral chordoma. Local recurrences, however, have often been observed even after total en bloc resection. The authors assessed outcomes in four cases of tumor recurrence in patients who underwent total en bloc S2-3 resection for sacral chordomas that were located below S-3. The primary recurrences were located at either side of the lateral portion of the remaining sacrum in all patients. In two patients in whom preoperative magnetic resonance imaging indicated no invasion of the tumor into surrounding soft tissues, recurrence in the resected end of the gluteus maximus or piriformis muscle was also observed. The authors therefore recommend that the S2-3 sacrectomy should be performed over an adequate margin, including a part of sacroiliac joints at the bilateral portions of the sacrum and soft tissues such as the gluteus maximus or piriformis muscle.

Sciatica of nondisc origin and piriformis syndrome: diagnosis by magnetic resonance neurography and interventional magnetic resonance imaging with outcome study of resulting treatment.

OBJECT: Because lumbar magnetic resonance (MR) imaging fails to identify a treatable cause of chronic sciatica in nearly 1 million patients annually, the authors conducted MR neurography and interventional MR imaging in 239 consecutive patients with sciatica in whom standard diagnosis and treatment failed to effect improvement. METHODS: After performing MR neurography and interventional MR imaging, the final rediagnoses included the following: piriformis syndrome (67.8%), distal foraminal nerve root entrapment (6%), ischial tunnel syndrome (4.7%), discogenic pain with referred leg pain (3.4%), pudendal nerve entrapment with referred pain (3%), distal sciatic entrapment (2.1%), sciatic tumor (1.7%), lumbosacral plexus entrapment (1.3%), unappreciated lateral disc herniation (1.3%), nerve root injury due to spinal surgery (1.3%), inadequate spinal nerve root decompression (0.8%), lumbar stenosis (0.8%), sacroiliac joint inflammation (0.8%), lumbosacral plexus tumor (0.4%), sacral fracture (0.4%), and no diagnosis (4.2%). Open MR-guided Marcaine injection into the piriformis muscle produced the following results: no response (15.7%), relief of greater than 8 months (14.9%), relief lasting 2 to 4 months with continuing relief after second injection (7.5%), relief for 2 to 4 months with subsequent recurrence (36.6%), and relief for 1 to 14 days with full recurrence (25.4%). Piriformis surgery (62 operations; 3-cm incision, transgluteal approach, 55% outpatient; 40% with local or epidural anesthesia) resulted in excellent outcome in 58.5%, good outcome in 22.6%, limited benefit in 13.2%, no benefit in 3.8%, and worsened symptoms in 1.9%. CONCLUSIONS: This Class A quality evaluation of MR neurography's diagnostic efficacy revealed that piriformis muscle asymmetry and sciatic nerve hyperintensity at the sciatic notch exhibited a 93% specificity and 64% sensitivity in distinguishing patients with piriformis syndrome from those without who had similar symptoms (p < 0.01). Evaluation of the nerve beyond the proximal foramen provided eight additional diagnostic categories affecting 96% of these patients. More than 80% of the population good or excellent functional outcome was achieved.

En bloc resection of primary sacral tumors: classification of surgical approaches and outcome.

OBJECT: En bloc resection with adequate margins is associated with the highest probability of long-term tumor control or cure in most cases of primary sacral malignancies. The authors present their experience with a systematic approach to these lesions. They provide a novel classification of surgical techniques based on the level of nerve root sacrifice and evaluate the functional and oncological outcomes. METHODS: Seventy-eight consecutive patients underwent 94 resections of sacral neoplasms at The University of Texas M. D. Anderson Cancer Center in Houston between August 1993 and June 2002. The records of 29 consecutive patients who underwent en bloc resection of primary sacral tumors were retrospectively reviewed. The median follow-up period was 55 months (range 1-103 months). Chordoma was the most frequent tumor type (16 cases). Midline sacral amputation was performed in 25 patients (eight low, four middle, seven high, and five total sacrectomies; one hemicorporectomy). Lateral sacrectomy was undertaken in four patients (two unilateral excisions of the sacroiliac joint and two hemisacrectomies). The surgical margins were wide in 19 cases, marginal in nine, and contaminated in one. The type of sacrectomy correlated with characteristic outcomes with respect to bladder, bowel, and ambulatory functions. Duration of hospital stay was related to the extent of sacrectomy (p = 0.003, Wilcoxon signed-rank test). The median Kaplan-Meier disease-free survival for patients with chordoma was 68 months (95% confidence interval 46-90 months). CONCLUSIONS: Classification of en bloc sacral resection techniques by the level of nerve root transection is useful in predicting postoperative function and the potential for morbidity. Adequate surgical margins should not be compromised to preserve function when they are necessary to affect tumor control.

[Usefulness of bone imaging in diagnosis of sternocostoclavicular hyperostosis].

Sternocostoclavicular hyperostosis (SCCH) is a rare disease that is characterized by hyperostosis and soft tissue ossification between the clavicles and the anterior part of the upper ribs. There have been few published reports of 99mTc-MDP bone imaging findings in this disease. Thirty-three patients who were suspected to have SCCH were studied with 99mTc-MDP bone imaging. Bone images were abnormal in 31 (94%) of 33 patients. Chest radiographs were available in 30 patients, but negative in 14 (46%) of them. Bone imaging revealed also radionuclide accumulations in other bones such as the vertebrae, femur or sacroiliac joints in ten (14 sites) of 33 cases. Bone scintigraphy was useful in the diagnosis of sternoclavicular hyperostosis.
