This article describes a case of a 58-year-old man with no significant underlying disease who had chronic pain due to osteonecrosis of the hamate. Following physical examination, imaging, and laboratory findings, he underwent surgical exploration via a limited dorsal approach. The hamate bone did not have a normal anatomical appearance or structure. It was marble-like in appearance, soft, friab...

Most of carpal tunnel syndrome cases are idiopathic, and secondary causes are so rare that can be easily missed. We present a patient with neglected undiagnosed lunate dislocation compressing on median nerve causing its signs and symptoms.

  Background: Abnormal angulation of the lunate can be an indication of intercarpal pathology. On magnetic resonance images (MRIs) the lunate often looks dorsally angulated, even in healthy wrists. The tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. The primary aim of this study was to det...

Posttraumatic instability of the wrist, resulting in scapholunate dissociation, is a common injury pattern in the wrist [2]. Mayfield et al. [1] described instability progressing sequentially from a scapholunate interosseous ligament (SLIL) tear to complete ligament failure around the lunate, resulting in lunate dislocation. Linscheid et al. [4] also demonstrated that excision of the dorsal rad...

Lunate and perilunate dislocations are uncommon, but they have clinical importance because complications, such as median neuropathy and avascular necrosis of the lunate, can occur. Although early diagnosis enabling early surgical treatment is crucial for preventing long-term sequelae, these dislocations are frequently missed in the initial assessment. Imaging tools, such as plain radiography, m...

Background: Since there is not a definite cause for Kienbock's diseases despite appropriate knowledge of lunate bone blood supply, so great debate about the ideal treatment protocol diseases. Objective: The aim this study to assess outcome combining distal capitate shortening and fusion base third metacarpal disease (Lichtman stage II or IIIA) with neutral ulna variance. Methods: Twenty patient...

The authors report their experience with the use of a vascularised pisiform bone graft based on the dorsal branch of the ulnar artery to provide osseous support and an efficient vascular aid especially in non-unions of the carpal navicular bone with avascular necrosis of its proximal pole and in stage III Kienböck's disease. The pisiform can replace the proximal pole of the navicular bone in to...

The callotasis lengthening technique was used to gradually lengthen the capitate after resection of the lunate in stage IIIa necrosis in 23 patients. Results of ten patients with a follow-up of at least 5 years showed rapid and sufficient callus formation in every patient regardless of age. The callotasis lengthening modification of the Graner II operation provides all advantages and avoids the...
