title: Rupture of the flexor tendons of the little finger in fractures of the hook of the hamate bone. Report of two cases.
abstract: Two cases of rupture of the flexor tendons of the little finger associated with a fracture of the hook of the hamate bone are presented. The preoperative diagnosis had not been made. Excision of the fractured hook and repair of the tendons by a short graft from the palmaris longus in one case and by the transfer of the superficial flexor of the ring finger in the other case gave a good final result. The authors remark on the rarity of reports of this fracture in the literature, the frequent occurrence of nonunion and the two complications which are exceptional; rupture of the flexor tendons and compression of the deep branch of the ulnar nerve. The fracture is mainly encountered in sports that require the grasping of a handle (tennis, golf, hockey, squash). The diagnosis is often missed at the onset because of not using the correct X-ray positioning: special incidence for the carpal tunnel view and a 3/4 view with the wrist in 45 degrees of supination and forced radial deviation.
