The Ilizarov hip reconstruction osteotomy for hip dislocation: outcome after 4-7 years in 14 young patients.

Treatment of neglected high dislocation of the hip is difficult in adults. We performed hip reconstruction osteotomy, consisting of a proximal abduction and extension osteotomy, and a distal varisation and lengthening osteotomy, utilizing the Ilizarov external fixator in 14 (12 women) patients having a mean age of 20 (12-33) years. The most frequent preoperative complaints were pain, leg-length discrepancy, limping, reduced activity and limited abduction of the hip. After an average follow-up of 68 (55-81) months, the outcome was satisfactory; pain subsided in all patients, the Trendelenburg sign became negative in all but 3 patients, no patient had limb-length discrepancy, and alignment of the extremity was reestablished. However, 3 patients still complained of lurch.

[A treatment algorithm for developmental dysplasia of the hip for infants 0 to 18 months of age and its prospective results].

OBJECTIVES: We evaluated the results of treatment in patients who were treated according to an algorithm established for developmental dysplasia of the hip (DDH) during the first 18 months of life. METHODS: We developed an algorithm for DDH to be used in infants at 0 to 18 months of age. Patients who did not respond to, or who did not have the indication for, the use of Pavlik harness were treated according to our algorithm and evaluated prospectively. Thirty-three hips (24 patients; 21 girls, 3 boys; mean age 7.4 months; range 2.5 to 18 months) were followed-up for a mean of 42 months (range 15 to 90 months). Ultrasonographic evaluation was performed using the Graf method. Avascular necrosis was evaluated according to the Kalamchi and MacEwen classification, and radiological results according to the Severin classification. RESULTS: The mean acetabular index angles before and after treatment were 37.3 degrees (range 20 degrees to 58 degrees ) and 21.8 degrees (range 15 degrees to 30 degrees ), respectively. According to the Kalamchi and MacEwen classification, six hips (18.2%) had type I, three hips (9.1%) had type II, and one hip (3%) had type III avascular necrosis. According to the Severin criteria, 21 hips were considered in group I, 10 in group II, and two hips in group III. Acetabular osteotomies were performed in four hips. All patients had full range of motion without any pain and limp. CONCLUSION: Successful clinical results obtained in the hips treated according to this algorithm for DDH may serve to justify its use as a standard algorithm in the treatment of infants at ages 0 to 18 months.

Surgical treatment of primary tumors of the sacrum.

Twenty-two patients with primary tumors of the sacrum were surgically treated between 1983 and 1997. Seventeen male and 5 female patients were followed up for a mean of 53.6 months (range 12-203 months). The histopathologic diagnoses were giant cell tumor (GCT) in 7 patients, chordoma in 4 patients, aneurysmal bone tumor in 3 patients, chondrosarcoma in 2 patients, osteoblastoma in 2 patients, synovial sarcoma in 2 patients, Ewing's sarcoma in 1 patient, and simple bone cyst in 1 patient. Currettage and thermo- or chemocauterization was applied to 8 patients, a subtotal sacrectomy was done in 11 patients, and total sacrectomy and lumbopelvic stabilization was done in 3 patients. The surgical margins were wide in all patients with GCT. The surgical margins were wide in 3 patients and wide contaminated in 1 patient with chordoma. The 2 patients with chondrosarcoma had high sacral lesions and were managed with total sacrectomy and lumbopelvic fixation. The surgical margin was wide in 1 patient and wide contaminated in the other, who relapsed locally and systemically in the 30th postoperative month. Three patients with aggressive aneurysmal bone cyst and 1 patient with simple bone cyst were managed by curettage and thorough debridement. One patient with low sacral Ewing sarcoma was managed by subtotal sacrectomy with wide margins. The two osteoblastomas were localized to the posterior elements of the sacrum. None of the patients relapsed. Most of the tumors of the sacrum are benign aggressive lesions or low grade malignancies. Intralesional resections in the form of curettage, with the addition of chemo- or thermocauterization, provide a complete cure for benign lesions. In contrast, wide resections are necessary for complete disease control in radio- and chemoresistant malignancies. Nerve root dissection should be performed in order to achieve wide margins.

Correction of complex foot deformities using the Ilizarov external fixator.

There are many drawbacks to using conventional approaches to the treatment of complex foot deformities, like the increased risk of neurovascular injury, soft-tissue injury, and the shortening of the foot. An alternative approach that can eliminate these problems is the Ilizarov method. In the current study, a total of 23 deformed feet in 22 patients were treated using the Ilizarov method. The etiologic factors were burn contracture, poliomyelitis, neglected and relapsed clubfoot, trauma, gun shot injury, meningitis, and leg-length discrepancy (LLD). The average age of the patients was 18.2 (5-50) years. The mean duration of fixator application was 5.1 (2-14) months. We performed corrections without an osteotomy in nine feet and with an osteotomy in 14 feet. Additional bony corrective procedures included three tibial and one femoral osteotomies for lengthening and deformity correction, and one tibiotalar arthrodesis in five separate extremities. At the time of fixator removal, a plantigrade foot was achieved in 21 of the 23 feet by pressure mat analysis. Compared to preoperative status, gait was subjectively improved in all patients. Follow-up time from surgery averaged 25 months (13-38). Pin-tract problems were observed in all cases. Other complications were toe contractures in two feet, metatarsophalangeal subluxation from flexor tendon contractures in one foot, incomplete osteotomy in one foot, residual deformity in two feet, and recurrence of deformity in one foot. Our results indicate that the Ilizarov method is an effective alternative means of correcting complex foot deformities, especially in feet that previously have undergone surgery.
