Outcomes of anterior interosseous nerve transfer to restore intrinsic muscle function after high ulnar nerve injury.

Traumatic high ulnar nerve injuries have historically resulted in long-term loss of hand function due to the long re-innervation distance to the intrinsic muscles. Transfer of the anterior interosseous nerve (AIN) to the deep motor branch of the ulnar nerve (MUN) is proving promising in these patients. The purpose of this study was to evaluate the outcomes and efficacy of this procedure in our series.

An evidence-based structured review to assess the results of common peroneal nerve repair.

Background: When is common peroneal nerve repair worthwhile? What is the effect of delayed repair? What is the maximum length of graft that can be used? This study aimed to address these questions by assessing the current literature and ascertaining the predictors of outcome that would guide peripheral nerve surgeons in determining the correct treatment of common peroneal nerve injury.

Methods: After an extensive literature review, 28 studies (1577 repairs) were assessed. The authors evaluated outcomes, using the British Medical Research Council grading for motor recovery, where M4 or above was considered a good outcome, and related them to delay, graft length, mechanism of injury, and age.
