Feasibility of a fascial flap to avoid anterior transposition of unstable Ulnar nerve: A cadaver study
نویسندگان
چکیده
BackgroundCompression of the ulnar nerve at elbow is second most frequent site compression in upper limb. Upon release, anteposition may be necessary to avoid dislocation latter when unstable. Numerous techniques are described literature (subcutaneous transposition, intramuscular subfascial medial epicondylectomy …), none which without complications. Based on Han's work, authors propose a technique covering with epicondylar fascial flap, avoiding but ensuring good stability nerve.MethodsAs part SICM (Italian Society Hand Surgery) cadaver dissection course (ICLO, Verona, Italy) dissected 36 elbows, 20 presented subluxation after its decompression. The flap was therefore made these coming from 14 different donors (9 men, 5 women) an average age 78 years. diameter then measured (at level passage cubital canal), newly formed canal, difference between two previous measurements (residual space flexed and it verified whether unstable once covered by flap.ResultsThe mean 5.1 mm (range 4–6), while neo-canal 10.1 8–11) extension 8.9 7–10) flexion. remaining canal 3.8 3–5).In cases dislocated having flap.ConlusionsIn light results obtained, think that use solution keep mind becomes following This work obviously needs clinical confirmation living patients.Level evidenceV.

Adipose Flap Versus Fascial Sling for Anterior Subcutaneous Transposition of the Ulnar Nerve.
Perineural scarring is a major cause of recurrent symptoms after anterior subcutaneous transposition secured with a fascial sling. Use of a vascularized adipose flap to secure the anteriorly transposed ulnar nerve can help reduce nerve adherence and may enhance nerve recovery. In the study reported here, we retrospectively reviewed the long-term outcomes of ulnar nerve anterior subcutaneous tra...
متن کاملThe role of ulnar nerve transposition in ulnar nerve repair: a cadaver study.
Ulnar nerve transposition at the elbow is recommended to diminish nerve gaps during neurorrhaphy. We undertook a cadaver study to determine the gap distance that can be overcome by subcutaneous transposition at the elbow, evaluating lacerations 2.0 cm distal to the medial epicondyle and 2.0 cm proximal to the wrist crease. With a 100-g load on each nerve stump, gaps that could be overcome were ...

The scientific meeting on Rehabilitation of the Disabled in Leprosy held at Vellore, Madras State, India, during November, 1 960 under the auspices of the W.H.O. recommended studies for further clinical research on peripheral nerves in general and ulnar nerve in particular. On the subject of clinical research on the ulnar nerve, the scientific session agreed ' that ulnar nerve transposition ant...
متن کاملAnterior subcutaneous transposition of the ulnar nerve.
Anterior, subcutaneous ulnar nerve transposition decompresses the ulnar nerve and, by transposing anterior to the medial epicondyle, eliminates longitudinal traction forces applied to the nerve during elbow flexion. This article reviews the indications and contraindications of the technique and describes the surgical technique in detail.
