Re-innervation of M. biceps by end-to-side nerve suture.
End-to-side nerve suture (ETSNS) is a viable option to re-innervate a paralysed biceps muscle. The host or donor nerve could be any of the adjacent large nerves including the brachial plexus. It is important to adhere to certain principles when performing ETSNS, e.g. epineural window only, suture line without tension, the recipient nerve should not "kink" in any way and complete immobilisation for at least three weeks. The earlier this ETSNS is done after injury the better the outcome. Patient co-operation and motivation is of the utmost importance. The post-operative rehabilitation programme is essential to "awaken" and strengthen the dormant muscle. Our results are based on five patients. Good elbow flexion, i.e. biceps contraction can be regained after ETSNS of, for example, the musculo-cutaneous nerve into an appropriate viable host nerve.
