Effect of a biplanar osteotomy on primary stability following high tibial osteotomy: a biomechanical cadaver study.

Open-wedge high tibial osteotomy (HTO) is becoming increasingly popular for the treatment of varus gonarthrosis in the active patient. The various implants used in HTO differ with regard to its design, the fixation stability and osteotomy technique. It is assumed that the combination of a plate fixator with a biplanar, v-shaped osteotomy supports bone healing.

The athlete's foot: the grey zone behind the ankle.

Posterior ankle and heel pain is common among athletes. The most common injury in this region is that of the Achilles tendon. However, besides the Achilles tendon, pain can originate from a retrocalcaneal bursitis, posterior impingement syndrome, os trigonum syndrome, or flexor hallucis longus tenosynovitis.

Dupuytren's disease: outcome of the proximal interphalangeal joint in isolated fifth ray involvement.

In this study of 38 patients, we assessed the clinical result following surgical treatment of Dupuytren's disease with isolated fifth ray involvement, particularly with respect to the proximal interphalangeal joint. Three surgical techniques were used: limited fasciectomy, segmental fasciectomy and dermofasciectomy. At a mean follow-up time of 53.

Osteoblastoma of the proximal ulna, an unusual cause of ulnar wrist pain. A case report.

During the diagnostic investigation of a patient with ulnar wrist pain, a hot spot in the proximal ulna was revealed on the technetium scintigram, which was found on radiographs to correspond to an osteolytic lesion in the proximal ulna. The lesion was resected and the histological diagnosis was an osteoblastoma. The wrist symptoms disappeared after resection of the lesion in the proximal ulna.

Benign fibrous histiocytoma of the posterior arch of C1 in a 6-year-old boy: a case report.

Study Design: Presented is a unique case report of a rare bone tumor: a benign fibrous histiocytoma (BFH) located in the posterior arch of C1 in a 6-year-old child.

Objective: To describe a benign fibrous histiocytoma of bone and the differential diagnostic considerations based on the authors' case report.

Summary Of Background Data: A BFH is a rare tumor composed of varying degree of fibroblast-like spindle cells, foam cells, and multinucleated giant cells.
