Carpal tunnel release is commonly performed to treat paresthesias, pain, and hand or wrist dysfunction. Despite it being a highly successful procedure, on occasion some patients may continue to suffer from persistent or recurrent symptoms after surgery. Techniques to manage recurrent symptoms range from nonoperative care including injections, splinting, and medications to revision surgery that may include a number of options such as local or distant flap coverage of the median nerve, nerve conduit placement, and/or utilization of vascularized tissues. This paper describes the technique of using a vascularized rotational muscle flap harvested from the flexor digitorum sublimis as a viable option to envelop the median nerve and promote healing during carpal tunnel revision surgery.
