Abstract
Surgical findings show important alterations of the extrinsic and intrinsic vascularity of the ulnar nerve in the epitroclear groove. Current procedures are only able to solve the mechanical aspect of nerve compression. Transposition may cause additional iatrogenic ischaemic damage of endoneural vascularity if the nerve is separated from the ulnar collateral artery to achieve anterior mobilization.
Our technique of transposition of the ulnar nerve with its vascular bundle maintains the advantages of anterior transposition currently in use, but is able to preserve the whole vascularity of the nerve, thus solving the biological aspect of nerve compression. This allows quicker recovery of axonal activity that was chronically compromised by the entrapment neuropathy.
The technique and the results in 30 patients (90% excellent and good, 10% fair) treated since 1987 are presented.
