Lesions of the dorsoradial compartment of the metacarpophalangeal joint of the thumb, are encountered more rarely than rupture of the internal collateral ligament and are considered a less serious or complex lesion. However, the alteration of the various structures, at the level of the metacarpophalangeal joint, produces, a severe deformity. It is an injury that requires early surgical repair of these structures. The author describes the physiopathology of the injury and the surgical technique for correcting the deformity on the basis of a series of operated cases.
