Applied anatomical study of the vascularized ulnar nerve and its blood supply for cubital tunnel syndrome at the elbow region
نویسندگان
چکیده
Cubital tunnel syndrome is often accompanied by paresthesia in ulnar nerve sites and hand muscle atrophy. When muscle weakness occurs, or after failure of more conservative treatments, anterior transposition is used. In the present study, the ulnar nerve and its blood vessels were examined in the elbows of 18 adult cadavers, and the external diameter of the nutrient vessels of the ulnar nerve at the point of origin, the distances between the origin of the vessels and the medial epicondyle of the humerus, and the length of the vessels accompanying the ulnar nerve in the superior ulnar collateral artery, the inferior ulnar collateral artery, and the posterior ulnar recurrent artery were measured. Anterior transposition of the vascularized ulnar nerve was performed to treat cubital tunnel syndrome. The most appropriate distance that the vascularized ulnar nerve can be moved to the subcutaneous tissue under tension-free conditions was 1.8 ± 0.6 cm (1.1-2.5 cm), which can be used as a reference value during the treatment of cubital tunnel syndrome with anterior transposition of the vascularized ulnar nerve.

Modified Simple Decompression of Ulnar Nerve in Treat-ment of Cubital Tunnel Syndrom
BACKGROUND There are two main surgical approaches, simple ulnar nerve decompression at the elbow, and anterior transposition of the nerve in treatment of cubital tunnel syndrome. Both techniques were reported in literature in details with similar reported success rates. Here, we present a modified simple de-compression surgical technique in treatment of cubital tunnel syndrome. METHODS Fifty...
متن کاملMorphology of the cubital tunnel: an anatomical and biomechanical study with implications for treatment of ulnar nerve compression.
PURPOSE The purpose of this study is to provide a thorough understanding of the anatomy of the cubital tunnel and to outline specific anatomical parameters of the cubital tunnel retinaculum (CuTR) that might aid in the management of ulnar nerve problems. The hypotheses of this study are (1) that the nerve elongates with elbow flexion and (2) that the cross-sectional area of the cubital tunnel i...
متن کاملEvaluation of etiologic findings in patients with surgery of cubital tunnel syndrome
Background: Cubital tunnel syndrome, a neuropathy of ulnar nerve, is the second most common entrapping syndrome in the upper limb surpassing carpal tunnel syndrome. This syndrome arises from a high pressure decompressing the nerve for a long time. Patients with cubital tunnel syndrome show numbness in the ring and small fingers. The aim of this study was to evaluate the etiology of cubital tunn...

Carpal tunnel syndrome (CTS) is the most well-known and frequent form of median nerve entrapment, and accounts for 90% of all entrapment neuropathies. Entrapment neuropathies of the ulnar nerve are relatively common with ulnar neuropathy at the elbow more prevalent than ulnar neuropathy at the wrist. The diagnosis of ulnar neuropathy at the elbow is usually confirmed in a relatively straight – ...
