Coracoclavicular screw fixation for unstable distal clavicle fractures

Fifteen patients with Neer type 11 distal clavicle fracture were treated surgically. Operative treatment included open reduction and fixation of the proximal clavicular fragment to the coracoid process using a 6.5-mm cancellous screw and repair of the coracoclavicular ligaments. Fracture union occurred at a mean of 7 weeks postoperatively without any serious complications. All patients returned to the pre-injury level of activity with no residual pain or dysfunction

Lateral malleolus en bloc resection and ankle reconstruction for malignant tumors

Four children and six adults required en bloc resection of the lateral malleolus for malignant tumors. There were four osteosarcomas. three chondrosarcomas, two Ewing’s sarcomas, and one adamantinoma. Surgical margins were wide in seven patients, marginal in two, and intralesional in one. A primary ankle arthrodesis was done in four adults and bracing without any reconstruction was done in four children and two adults. During a mean followup of 14.5 years (range, 3-30 years), there were two local recurrences (two of 10 patients) after a marginal excision and an intralesional excision. One patient had reoperation for a skip osteosarcoma lesion in the proximal fibula. Other complications included chronic osteomyelitis, a lateral talus subluxation and cavovarus deformity, and recurrent ankle instability and degenerative changes of the ankle. At the latest followup, all 10 patients showed no evidence of disease. Five patients who had primary or late ankle arthrodesis had a Musculoskeletal Tumor Society, and International Society of Limb Salvage functional score of 28 points (92%), and two adolescents who had postoperative bracing alone had a functional score of 24 points (80%). The three remaining patients had a salvage amputation. Level of Evidence: Therapeutic study, Level IV (case seriesno, or historical control group).

Percutaneous harlow wood needle biopsy of the spine: A retrospective analysis of 238 spine lesions

This retrospective study assessed the diagnostic accuracy and clinical usefulness of the Harlow Wood needle biopsy for spinal lesions. The medical records of 238 patients (138 men and 100 women) who underwent closed spine biopsy from 1987 through 1997 were reviewed. Patient age ranged from 21 to 83 years. Lesions involved the thoracic vertebrae in 127 patients, the lumbar vertebrae in 99 patients, and the sacrurn in 12 patients. Cultures of the biopsy specimens were examined histopathologically and cytologically. One hundred twenty-four patients were diagnosed with a spinal infection, and 68 patients were diagnosed with a tumor. In the remaining 46 patients, the biopsy specimens were negative for infection or neoplasia in 20 patients and not diagnostic in 26 (10.9%) patients. There were no major complications. The Harlow Wood needle biopsy is a simple, repeatable procedure with satisfactory diagnostic accuracy (89.1%) and can be performed on an outpatient basis
