Abrasion arthroplasty as a salvage for failed upper tibial osteotomy.

Eight patients with persistent pain after upper tibial osteotomy and correction of malalignment were treated with abrasion arthroplasty of the affected compartment. At 34-month follow-up examination, only one patient had significant lasting benefit. Five of the patients required subsequent total knee arthroplasty for relief of their pain. One patient was symptomatically unchanged, and one was awaiting total knee arthroplasty. The authors conclude that abrasion arthroplasty is not a satisfactory salvage for a failed upper tibial osteotomy.

Periosteal osteosarcoma.

Periosteal osteosarcoma is a surface lesion without evidence of medullary involvement. This report extends the Mayo Clinic series of periosteal osteosarcoma cases from 11 to 22 cases. In a review of demographic information from our 22 cases and from 30 additional cases, referred only for pathologic diagnosis, the average age at the time of diagnosis in our series was 20.5 years. The proximal tibia was the most frequent site of tumor. Men and women were affected in approximately equal numbers. Limb pain and swelling were common complaints, as were findings of limb mass and tenderness. Excision of a tumor demands at least wide margins. When surgical margins were less than wide, there were higher rates of local tumor recurrence and tumor metastasis. A relatively high rate of tumor recurrence and metastasis occurred with femoral lesions despite wide excisional margins, suggesting that femoral lesions may need more aggressive surgical treatment.

Radial tunnel syndrome. A ten-year surgical experience.

In a ten-year experience with radial tunnel syndrome surgery, 34 of 42 patients had follow-up examination of more than six months (average, 24 months). Although 74% of the patients were improved after surgery, about one-third had some persistent pain and functional restriction. Static electromyographic analysis was not diagnostically helpful. However, diagnostic radial tunnel block was prognostically helpful. Patients selection was important in predicting surgical outcome. In worker's compensation cases, symptoms would often persist. Some patients also appeared to have symptoms referable to compression of the posterior interosseous nerve and tendinitis of the extensor origin, and others had additional ipsilateral compressive neuropathies.

Nonoperative treatment of traumatic dislocations of the extensor digitorum tendons in patients without rheumatoid disorders.

Traumatic subluxation and dislocation of the extensor digitorum tendons are uncommon in patients without rheumatoid disorders. Management of the acute injury is not well defined in the orthopedic literature. Two cases of traumatic dislocations of the extensor digitorum tendon were seen acutely in young persons without rheumatoid disease. These patients were successfully managed by early closed reduction and immobilization. This treatment had yielded good hand function to date, without recurrence of the dislocation. One of these cases was particularly unusual in that the direction of the tendon dislocation was radial. This particular injury has not been previously described.
