Osteoid osteoma of the hook of hamate: An unusual cause of ulnar side wrist pain

Ulnar side wrist pain is a complex clinical situation because of the pathologies involving multiple closely located structures on the ulnar side of the wrist. Incidence of osseous lesions leading to ulnar side wrist pain is very rare. The effectiveness of commonly employed Magnetic resonance imaging, for diagnosing the pathology in the ulnar side of the wrist might be limited in diagnosing such osseous lesions and can lead to missed diagnosis. We herein present such a rare case of Osteoid osteoma of the hook of hamate presenting as ulnar side wrist pain. The condition, presented a "diagnostic challenge", where it required Computed Tomography to diagnose and guide for appropriate management.

Hamate hook stress fracture in a professional bowler: Case report of an unusual causal sport

Stress fracture of the hook of the hamate is uncommon and is usually seen in sports involving a club, racquet or bat (i.e., golf, tennis or baseball). It is caused by direct blunt trauma. We report an unusual case of stress fracture with non-union in a 23-year-old professional bowler, probably caused by endogenous constraints, 1 year after the start of symptoms. Treatment consisted of surgical resection of the hook of the hamate. Multimodal imaging of this fracture is reviewed.

Closed Rupture of the Flexor Tendon Secondary to Sclerosis of the Hook of the Hamate: A Report of Two Cases

Closed flexor tendon ruptures in the little finger can be caused by fracture or nonunion of the hook of the hamate, but no case of the disorder secondary to the sclerosis and thinning of the hamate hook has been reported. We report two rare cases with this complication due to rough surface of the hamate hook. Carpal tunnel view radiographs and computed tomography showed the sclerosis and thinning of the hook.
