Answer

In a retrospective study by Charles et al, 49 patients who underwent ulnar nerve transposition were followed to assess clinical sensory and motor recovery in cubital tunnel syndrome and to determine whether recovery is influenced by such factors as preoperative McGowan stage, age, and symptom duration. [142] Submuscular transposition was used in 25 patients, and subcutaneous transposition was applied in 24 patients.

Obvious improvement was reported in 20 of the 25 patients in the submuscular group and in 17 of the 24 patients in the subcutaneous group. [142] Both groups showed significant improvement in sensory and motor function, with 17 patients in each group recovering sensory function and 19 in each group recovering motor function. Patients with symptoms lasting longer than 6 months had a poor prognosis, regardless of the surgical technique used.

Jaddue et al compared operative technique (incision length and operating time), postoperative care (postoperative pain and complications), and outcome between subcutaneous and submuscular surgical techniques for anterior transposition of the ulnar nerve after decompression in moderate cubital tunnel syndrome. [178] Subcutaneous transposition was found to be associated with a shorter incision, reduced operating time, less postoperative pain, fewer postoperative complications, and better outcome.
