Intramedullary wire fixation for unstable forearm fractures in children.

Displaced fractures of the diaphyseal forearm in children are often treated conservatively, but there is relatively high incidence of redisplacement, malunion and consequent limitation of function. This retrospective study was performed to determine means for minimalising the complications of intramedullary Kirschner (K)-wire fixation used in the treatment of unstable, diaphyseal forearm fractures by pointing out those which most frequently occur with this treatment choice. This treatment method was applied in 48 children with a mean age of 10.3 (range, 5-14) years. A limited open reduction to one or both bones was necessary for insertion of the intramedullary wire in 20 (40%) patients. Although 24 complications, such as pin site infection, loss of forearm rotation, superficial branch of radial nerve palsy, delayed union, nonunion, hardware migration, and K-wire penetration to the opposite cortex, were recorded in 18 patients, 46 patients (96%) had excellent or good, 1 patient (2%) had fair and 1 patient (2%) had poor outcome using the grading scheme adapted by Price. Except for the patient in whom the fracture was not united, the average union time was 6.3 weeks in children less than 10 years and 7.8 weeks in those above 10 years of age. Despite these minor complications, percutaneous intramedullary fixation with K-wires and proper technique is an appropriate, effective and safe operation for unstable diaphyseal fractures of the forearm in children who cannot be treated by closed manipulation.

[Capsuloperiosteal flap application for the stabilization of chevron osteotomy].

OBJECTIVES: We retrospectively analyzed the results of capsuloperiosteal flap application to stabilize modified distal chevron osteotomy in patients with mild to moderate intermetatarsal and hallux valgus angles. METHODS: Modified chevron osteotomy was performed in 27 feet of 25 patients (14 females, 11 males; mean age 30.4 years; range 19 to 43 years) with hallux valgus. The study group was comprised of patients unresponsive to conservative treatment for painful deformity, at ages 18 to 50 years, and having an intermetatarsal angle less than 17 degrees, hallux valgus angle less than 40 degrees, and no osteoarthritic changes in the metatarsophalangeal joint. The patients were evaluated clinically and radiographically preoperatively and in the early postoperative period, in the sixth week, and once in every six weeks. Clinical assessments were made using the subjective and objective evaluation systems of Bonney and Macnab. The mean follow-up was 22 months (range 8 to 67 months). RESULTS: The mean preoperative hallux valgus angle, which was 31.4 degrees (range 23 degrees to 40 degrees), decreased to 12.8 degrees (4 degrees-22 degrees) postoperatively, with a corresponding decrease in the intermetatarsal angle from 14.2 degrees (11 degrees-17 degrees) to 9.6 degrees (7 degrees-14 degrees). Conformity of the first metatarsophalangeal joint was complete in all the cases. According to the Bonney and Macnab subjective scores, the results were excellent in seven feet (25.9%), good in 17 feet (63%), and moderate in three feet (11.1%). On objective evaluations, the results were excellent in 14 feet (51.9%), good in 11 feet (40.7%), moderate in one foot (3.7%), and poor in one foot. CONCLUSION: Our results suggest that modified chevron procedure whose stability is improved by the use of a capsuloperiosteal flap without using any internal fixation material is an effective alternative for the treatment of patients with moderate degrees of hallux valgus without metatarsophalangeal joint degeneration.

Squamous cell carcinoma arising in chronic osteomyelitis in foot and ankle.

BACKGROUND: Squamous cell carcinoma arising from chronic osteomyelitis is uncommon, and although most occur in the lower extremities, occurrence in the foot and ankle is rare. METHODS: Between February, 1991, and May, 2003, we treated 14 patients (13 men and one woman) with squamous cell carcinomas arising in chronic osteomyelitis. The foot and ankle were affected in seven patients, and these comprised our study group. All seven patients were male, with a mean age of 59.5 (range 54 to 63) years. An average of 27 (range 4 to 50) years passed between draining of the osteomyelitis and the diagnosis of the malignancy. Average followup was 68 (22 to 147) months. RESULTS: Six patients had amputations and one had limb salvage. Regional lymph node clearance was done in four patients, but metastasis occurred in only one patient who later died of the disease. CONCLUSION: In treating recalcitrant ulcers that have not responded to conventional modes of therapy, malignancy should be ruled out and a biopsy done. The treatment of choice for squamous cell carcinoma is amputation. Routine regional lymphadenectomy at the time of amputation seems unnecessary, but regional lymphadenopathy persisting for 3 months after amputation warrants surgical intervention.

[The development of osteosarcoma following radiotherapy for fibrous dysplasia].

Sarcoma arising from fibrous dysplasia (FD) is rare and it is more common in polyostotic type. In this case report, we present a 41-year-old male patient who developed osteosarcoma of the left tibia 28 years after the initial diagnosis and 20 years after radiation therapy for FD. He underwent above-knee amputation, but died eight months after surgery. This case suggests that radiotherapy has no beneficial effect in the treatment of FD and that it may be associated with the development of sarcoma.

[Simultaneous asymmetric bilateral traumatic hip dislocation: a case report].

Asymmetric bilateral (one side anteriorly, the other posteriorly dislocated) traumatic hip dislocations are very rare. We present a 21-year-old male patient who had simultaneous anterior and posterior traumatic hip dislocations due to a car crash. He also suffered from a tarsometatarsal (Lisfranc's) fracture-dislocation. The patient underwent conservative treatment and was followed-up for 44 months. Final evaluations with Thompson and Epstein radiologic and clinical criteria showed an excellent result. To our knowledge, this is the first report of a case with asymmetric bilateral traumatic hip dislocations associated with Lisfranc's injury.
