Ulnar nerve entrapment at the wrist: Cases from a hand surgery practice

摘要: Background Eight patients with 11 instances of wrist-level ulnar nerve entrapment, a fairly uncommon compression syndrome, were identified in hand surgery practice from 1992 through 1996. Methods Presentations, causes, and surgical outcomes examined, the pertinent literature was reviewed. Results All eight had extrinsic, nonidiopathic caused by tumor, vascular disease, anomalous muscle development, or tight fibrous arch at origin flexor digiti minimi. In all cases, sensory symptoms resolved removal cause compression. Conclusions These cases serve to remind physicians that not every instance numbness tingling represents carpal tunnel syndrome. Careful clinical examination may only localize wrist level but also reveal its etiology. Some causes compressive neuropathy, however, are apparent exploration.
