[Surgical treatment of carpometacarpal joint osteoarthritis of the thumb by trapeziectomy-interposition-ligamentoplasty].

Introduction: Osteoarthritis of the carpometacarpal joint of the thumb is a common pathology. Several surgical methods exist, including trapeziectomy, arthrodesis, cemented or cementless prosthesis. Therefore, one must question the legitimacy of non prosthetic surgery.

[Rhabdomyosarcoma of the hand. Apropos of a case confined to the thenar eminence].

A case of alveolar rhabdomyosarcoma of the hand in a 21-year-old patient is reported. In the light of this case, the authors review the literature and analyse the therapeutic implications.

[Mirror-image osteosarcoma of the radius. A case].

Multiple osteosarcoma is a rare tumour which usually has a poor prognosis. We report the case of a 14-year old girl who developed successively, at 2 1/2 years' interval, one osteosarcoma of the right radius bone, then one of the left radius bone. The tumours were strictly symmetrical.

Pouteau-Colles fracture: double-closed "basket-like" pinning according to Kapandji. Apropos of a homogeneous series of 70 cases.

First described by Kapandji, the double closed "basket-like" pinning is a new and quite attractive treatment of the Colles' fracture. With or without XR TV, following closed reduction the epiphysis is fixed steady with two Kirschner wires, sliding along its lateral and its posterior aspects, entering the radius at the fracture site and transfixing the bone cortex above. Plaster cast is unnecessary, and wrist reeducation begins on the first day post-op.
