Arguments for an increasing differentiation towards fibrocartilaginous components in midportion Achilles tendinopathy.

Purpose: The objective of this study was to investigate the fibrocartilaginous differentiation occurring in midportion Achilles tendinopathy.

Methods: Tendon samples were retrospectively collected from 23 patients, who had undergone surgery for midportion Achilles tendinopathy resistant to conservative treatment. Based on histological scores, the biopts were subdivided into three categories: a light, moderate and severe histopathological stage.

Scarf osteotomy for hallux valgus deformity: a prospective study with 8 years of clinical and radiologic follow-up.

Background: Scarf midshaft metatarsal osteotomy has become increasingly popular as a treatment option for moderate-to-severe hallux valgus deformities because of its great versatility. Numerous studies on Scarf osteotomy have been published. However, no prospective studies were available until 2002.

Bolt fixation for syndesmotic injuries.

We performed a retrospective study of 28 patients who underwent bolt fixation for a syndesmotic injury to the ankle. The mean follow-up period was 66 months (range: 24-139 months). The results of surgery were assessed clinically and radiographically.

The fibula pro tibia procedure in the treatment of nonunion of the tibia.

We reserve the fibula pro tibia procedure for infected nonunions or for cases that already have been subjected to one or more other methods of treatment. The fibula pro tibia procedure is a technically simple one-stage procedure. The site of the pseudarthrosis is not exposed; hence there is less risk of recurrent infection.

Surgical treatment of tibial pseudarthrosis using the Ilizarov apparatus. A critical analysis.

Since November 1985 the authors have added the Ilizarov procedure to their armamentarium for the treatment of tibial pseudarthrosis. The results of a first clinical study of 10 patients are reported. The mean duration of follow-up is 17 months.
