[Operative treatment of cubital tunnel syndrome and late ulnar paralysis by simple decompression. Report on 108 cases].

A follow-up study of 108 cases of cubital tunnel syndrome and tardy ulnar palsy, treated by simple decompression without transposition of the ulnar nerve is presented. Division and resection of the fibrous arch between the two heads of the flexor carpi ulnaris proved to be an efficacious and entirely satisfactory substitute for the more complicated and extensive procedure of volar transposition of the ulnar nerve not only for the cubital tunnel syndrome but also for tardy ulnar palsy and luxation of the ulnar nerve. Only in cases of severe cubitus valgus deformation of the elbow joint is primary transposition of the nerve recommended. Surgical decompression should be done early to get a more complete recovery in a greater number of patients.
