Optimizing functional upper extremity reconstruction-Simultaneous free anterolateral thigh flap and tendon...

Composite upper extremity defects involving muscle-tendon units are amongst the most formidable reconstructive challenges and mandate functional restoration in addition to stable soft-tissue coverage. Here, the authors present a case of a composite defect involving the extensor muscle-tendon units of the forearm resulting from surgical resection of a recurrent Merkel cell cancer. Functional restoration was achieved via multiple tendon transfers followed by soft tissue coverage with a free anterolateral thigh (ALT) flap. No donor- or recipient-site complications were encountered and complete flap survival was noted. Following a 6-week period of immobilization, physical therapy and range of motion exercises were initiated. Excellent functional outcome and high patient satisfaction were noted at 8 weeks postoperatively. In summary, simultaneous tendon transfers and microsurgical tissue transfer may provide a potentially superior approach for upper extremity reconstruction in complex composite defects. © 2014 Wiley Periodicals, Inc.
