[Stabilized arthroplasty of the 5th metacarpal bone. A therapeutic proposal for the treatment of old fractures-luxations of the 5th metacarpal bone].

The goals of the surgical treatment of fracture-dislocations of the fifth ray are length restoration of the fifth metacarpal, release of impingement and preservation of the carpo-metacarpal mobility. Our technic of "stabilised arthroplasty" satisfies theoretically to these three goals. It consists in resection-arthroplasty of the base of the fifth metacarpal associated with stabilisation by arthrodesis between fourth and fifth metacarpal.
