[The dorsoradial flap: a new flap for hand reconstruction. Anatomical study and clinical applications].

The authors report a new cutaneous flap harvested from the dorsal and distal quarter of the forearm: the dorsoradial flap. The vascularisation type of the cutaneous paddle belongs this flap to the anterograde and axial family flaps. The anatomical study carried out on thirty six fresh cadaver upper arms showed a constant and a consistent cutaneous collateral branch of the radial artery which arises at the apex of the first intermetacarpal space.

[The Omega "Omega" pulley plasty. A new technique to increase the diameter of the annular flexor digital pulleys].

The authors report a new technique of pulley plasty of the flexor digital system. It is not an operative procedure to reconstruct a damaged pulley but an original way to expand the volume of an intact pulley in order to adapt its volume to the diameter of the repaired flexor tendon. The flexor tendons ruptures in Verdan zone II and particularly in Tang zones IIA and IIB are often accompanied by an osteofibrous tunnel injury.

[The Omega "Omega" pulley plasty: a new technique for the surgical management of the De Quervain's disease].

The Omega "Omega" pulley plasty: a new technique for the surgical management of the De Quervain's disease. The De Quervain tenosynovitis is an inadequacy into the first extensor compartment between the osteo-fibrous tunnel and the tendons. This mechanical conflict generates a tenosynovitis of the extensor pollicis brevis and the abductor pollicis longus tendons.

[Acetabulum without cement. Short-term results of a series of 112 threaded cups].

Between January 1982 and December 1987 we used 112 threaded acetabular cups in 102 patients undergoing total hip replacement. The clinical and radiographic results of 107 implants are reported in this survey. Using the functional grading of the hip advocated by Merle d'Aubigné and Postel, 62% can be classified as excellent, very good or good.
