Ilizarov treatment of pilon fractures.

The authors retrospectively reviewed 13 pilon fractures in 12 patients treated with a diaphyseal-epiphyseal technique of Ilizarov external fixation. Clinical followup averaged 16 months (range, 12-25 months). Eighty-four percent of the fractures had healed within 16 weeks after surgery. Average range of motion of the ankle was 12 degrees dorsiflexion and 25 degrees plantar flexion. One delayed union was treated with bone grafting and eventually healed; 1 nonunion was treated with ankle arthrodesis. Most patients (91%) experienced mild or no pain. There were no deep infections. This technique is an effective treatment option for tibial pilon fractures.

Wrist arthrodesis in post-traumatic arthritis: a comparison of two methods.

The Arbeitsgemeinschaft für Osteosynthesefragen arthrodesis technique is compared with the proximal row carpectomy technique with radiocapitohamate arthrodesis for patients with traumatic and degenerative arthritis of the wrist. Both techniques gave satisfactory functional and x-ray film results in 85% of the patients. Grip strength measured on the Jamar dynamometer at settings 1-5 was 77-83% of the opposite in the dominant extremities and 56-82% of the opposite in the nondominant extremities. Despite the decrease in grip strengths after wrist fusion, grip strength curve patterns were similar for operated and nonoperated extremities. There were no statistically significant differences in grip strength between the two groups. Patients who did not have index and long ray carpometacarpal joints fused had pain at that level requiring a second procedure to arthrodese the joints. Index and long finger carpometacarpal joint arthrodesis at the time of wrist arthrodesis is recommended in patients with heavy labor jobs.

Solitary fibromatosis of bone. A rare variant of congenital generalized fibromatosis.

Congenital generalized fibromatosis is part of the spectrum of the fibromatoses of infancy and childhood. The lesions are usually multiple and fibrous in nature. They may appear in virtually every organ outside the central nervous system. Congenital generalized fibromatosis can be limited to the skeleton and rarely manifests itself as a solitary bone lesion. Solitary osseous lesions often behave differently than multiple osseous lesions. Solitary lesions often do not regress without treatment and can have a high incidence of recurrence with less than marginal excision. Multiple osseous lesions often regress without treatment.

Isolated arthroscopic partial meniscectomy. Functional radiographic evaluation at five years.

Fifty patients who underwent isolated arthroscopic partial meniscectomy with a minimum followup of 5 years were analyzed retrospectively. To analyze the factors associated with a satisfactory or an unsatisfactory clinical result, we looked at the patient's age, duration of symptoms, type of meniscal lesion, and articular cartilage abnormalities. The patients were graded with a functional knee score (Lysholm-Gillquist), and activity level before surgery and at followup was determined. The data also included radiographic evaluation of 29 of the 50 patients. Tibiofemoral alignment was measured, and osteoarthritic changes were graded and correlated with the type of meniscal abnormality and functional result. Eighty-two percent of our patients had satisfactory knee function, and the activity level was maintained. The factors associated with a satisfactory result after a partial meniscectomy included age less than 40 years, symptoms less than 12 months duration, type of tear, and chondromalacia less than grade II. Fairbank's changes were present in 50% of the patients, with significant grade III and IV changes identified in 30%. Although the radiographic changes did not necessarily correlate with the functional result, we felt that the changes were significant and indicative of abnormal stress transfer to articular cartilage and bone.
