Question

Choose all that apply to a motor nerve transfer (for example, when used to regain muscle innervation after the original peripheral nerve supply was damaged) It is just as good to use a sensory nerve as a motor nerve as the donor nerve There is no difference in outcome with an EtE (end to end) versus EtS (end to side) nerve transfer We can surgically repair "wrist drop" using a median to radial nerve

Answer 1

Motor nerve transfers are surgical procedures to restore muscle function, with motor nerves preferred over sensory for reinnervation. Wrist drop can sometimes be repaired by transferring fibers from the median to the radial nerve. End-to-end and end-to-side nerve transfers have different outcomes and are chosen based on the specifics of the injury.

Step-by-step explanation:

A motor nerve transfer is a surgical procedure used to restore muscle function after damage to the original peripheral nerve supply. In these cases, the choice of nerve (sensory or motor) as well as the type of nerve connection (end-to-end (EtE) or end-to-side (EtS)) can significantly impact the outcome of the surgery.

Using a motor nerve is typically preferred for reinnervating muscles because motor nerves have the appropriate types of nerve fibers needed for restoring muscle function. While sensory nerves can sometimes be used, they are not ideal due to differences in the types and functions of the fibers.

Surgical repair of 'wrist drop' can sometimes involve transferring fibers from the median nerve to the radial nerve to restore function, demonstrating one practical application of nerve transfers in addressing motor deficits.

Surgical outcomes may differ depending on whether an EtE or EtS nerve transfer is performed. Each approach has its own indications and potential benefits, and the specific technique is chosen based on the unique circumstances of the nerve injury.
