Osteonecrosis of the trapezium: a case report and review of the literature.

We describe the case of a 58-year-old woman with AVN of the left trapezium which was treated surgically. This paper aims to review the etiologies leading to the pathology and the different therapeutic options. Avascular necrosis (AVN) of the carpal bones most commonly involves the lunate and the scaphoid .

Conservative treatment versus scaphotrapeziotrapezoid arthrodesis for Kienbock's disease. A retrospective study.

Efficiency of surgical treatment in Kienböck's disease has never been proven in the long term. We retrospectively reviewed the charts of the 104 patients treated by various techniques for Kienböck's disease from 1981 to 1999 in our unit. A comparison was made between 19 cases treated conservatively (amongst 59) and 11 cases (amongst 25) treated by scaphotrapeziotrapezoid (STT) arthrodesis with a mean follow-up of 13 years.

Relationship between dorsal ganglion cysts of the wrist and intraosseous ganglion cysts of the carpal bones.

Soft tissue ganglion cysts are the most common benign tumours of the wrist; their pathogenesis remains controversial. We prospectively screened the radiographic appearance of the wrists of 51 patients presenting to a single surgeon with dorsal wrist ganglions during a one-year period. Postero-anterior and lateral radiographs were systematically performed looking for possible associated intraosseous ganglion cysts.
