Hamate hook nonunion initially mistaken for ulnar nerve compression: acase report with review of literature. The hook serves as the origin of the flexor and opponens digiti minimi muscles and forms the ulnar border of the carpal tunnel and radial border of Guyon's canal.1 The deep motor branch of the ulnar nerve courses around the base of the hook with the superficial sensory branch remaining in close contact with the tip. There was no significant difference between preinjury and postoperative performance scores. Methods: Epub 2013 Jul 26. The small size of the fragment and precarious vascular supply adds complexity and uncertainty to this procedure.1,10 Thus, excising the fractured hook remains the gold standard among operative procedures.1,24,25 A volar approach is used, with care to identify and protect the surrounding neurovascular and tendinous structures. Displaced hamate fragments and haematoma, as well as nonunion of the hook of the hamate, can lead to neuropathy of the deep branch of the ulnar nerve, lesion of the median nerve, or even rupture of deep flexor tendons IV and V. The fracture fragments may injure the nerves directly or swelling and inflammation may injure them indirectly. 6. Open reduction and internal fixation (screws or Kirschner wires) is another proven treatment.

Hand Surg. Routine anteroposterior, lateral, and oblique wrist radiographs often do not reveal the fracture.1,17,21 Subtle radiographic signs on anteroposterior projections include (1) absence of the hook, (2) lack of cortical density, and (3) sclerosis.1 Special projections can be useful in establishing the diagnosis.

The treatment for these fractures ranges from nonoperative immobilization to excision of the fragment. The vascular anatomy of the hamate hook has been extensively evaluated.17 Vessels penetrate the radial base as well as the ulnar tip with relatively poor vascular anastomoses between the two.7,17 This resultant vascular watershed predisposes even nondisplaced hook fractures to nonunion.1,17,18 Clinical Features and Evaluation In most cases Physiopedia articles are a secondary source and so should not be used as references.
