[Comparison between trapezectomy and silicon implant in the treatment of rhizarthrosis]. / Comparaison entre trapézectomie et implant de silicone dans le traitement de la rhizarthrose.

Among 19 cases of arthritis of the basal joint of the thumb, 12 were operated according to the technique of Swanson, and 7 by simple trapezectomy. Similar results were observed with both techniques.

Fingertip amputations: distal or advancement flaps.

Fingertip amputations treated with conventional flaps gave consistently good coverage, but the recovery of sensibility was superior in advancement flaps. Residual pain, however, was less frequent in distal flaps. Work incapacity averaged between 6 and 8 weeks.

[Diagnosis of rupture of the ulnar collateral ligament of the metacarpophalangeal joint of the thumb. Presentation of a simple clinical and radiological test]. / Diagnostic des ruptures du ligament collatéral cubital de l'articulation métacarpo-phalangienne du pouce. Présentation d'un test clinique et radiologique simple.

When a normal thumb is attached to a rubber band and pulled in a radial direction, the MP joint adopts an attitude of abduction, internal rotation and, most often, slight flexion. Under the same conditions, rupture of the ulnar collateral ligament (UCL) expresses itself by an increase of abduction of at least 10 degrees, by an increase of flexion of at lest 10 degrees and, frequently more evidence, is provided by a decrease of rotation of at least 20 degrees. These clinical observations were also found on unembalmed corpses. They allow one to detect easily and without local anesthesia the recent and old ruptures of the UCL.
