A Case of Distal Ulnar Nerve Variation – Presence of Sensory Loop around the Hook of the Hamate Bone
نویسندگان
چکیده
Ulnar nerve variations in the wrist are rare but still have clinical importance. In the course of a routine dissection of the right hand of a 67-y-old Caucasian male cadaver an aberrant ulnar nerve at the wrist was found. Its superficial branch bifurcated and formed a complete loop around the hook of the hamate bone. The sensory digital nerves arose from the different parts of this loop. The presence of such a variant neural loop predisposes the nerve to compression neuropathy and accidental injury during surgical interventions.

Guyon's canal revisited: an anatomic study of the carpal ulnar neurovascular space.
The boundaries of the space through which the ulnar neurovascular bundle crosses the wrist have been reinvestigated. Using gross dissections, transverse and sagittal sections, and histologic study, we determined that the roof of Guyon's canal, the "carpal ulnar neurovascular space," does not directly connect to the hamate bone, as is currently accepted. The roof of this space extends radially t...
متن کاملThe Prevalence of Unanticipated Hamate Hook Abnormalities in Computed Tomography Scans: A Retrospective Study
Background:It is possible that some hamate hook fractures are not diagnosed or treated, thereby affecting the study of their natural history. Study of the prevalence of incidental hamate hook fractures, nonunions, and other abnormalities on computed tomography (CT) ordered for another reason could document a subset of undiagnosed and untreated hamate hook fractures which might change our under...
متن کاملInjury to the deep motor branch of the ulnar nerve during carpal tunnel release.
Complications following carpal tunnel release have been reported to occur in 12-20%’ of cases and are numerous and varied. Neurologic complications that have been reported usually involve the palmar cutaneous or motor branch of the median nerve.’ Ulnar nerve injury during carpal tunnel release has been reported rarely. The only cases reported include cases of injury to the main ulnar palmar cut...
متن کاملUlnar nerve palsy after open carpal tunnel decompression: Case report and review of the literature
Open carpal tunnel release is the commonest surgical treatment of median nerve compression at the wrist. Although successful in most cases, there are well described complications. We report a case of laceration of the deep motor branch of the ulnar nerve at the level of the hook of hamate following a complicated carpal tunnel decompression. Good surgical technique and knowledge of wrist anatomy...
متن کاملUlnar nerve entrapment at the wrist.
MEDIAN nerve compression at the wrist is common and its treatment by decompression is usually successful. Ulnar nerve entrapment, on the other hand, is uncommon. The ulnar nerve as it enters the hand passes through and divides in the canal of Guyon, into its deep (motor) and superficial (sensory) branch. This ulnarcarpal tunnel is bounded proximally and medially by the pisiform, distally and la...
