BACKGROUND: The pedicled latissimus flap has been shown to provide effective coverage of wounds around the elbow with an average size of 100 to 147 cm2 but with complication rates of 20% to 57%. We believe the pedicled latissimus dorsi flap is an effective and safe technique that provides reliable and durable coverage of considerably larger soft tissue defects around the elbow and proximal forearm. METHODS: A retrospective review was performed including all patients from Harborview Medical Center between 1998 and 2012 who underwent coverage with pedicled latissimus dorsi flap for defects around the elbow. Demographic information, injury mechanism, soft tissue defect size, complications (minor vs major), and time to surgery were collected. The size of the soft tissue defect, complications, and successful soft tissue coverage were the primary outcome measures. RESULTS: A total of 18 patients were identified with variable mechanisms of injury. Average defect size around the elbow was 422 cm2. Three patients had partial necrosis of the distal most aspect of the flap, which was treated conservatively. One patient required a secondary fasciocutaneous flap, and another required conversion to a free latissimus flap secondary to venous congestion. Two were lost to follow-up after discharge from the hospital. In all, 88% (14 of 16) of the patients had documented (>3-month follow-up) successful soft tissue coverage with single-stage pedicled latissimus dorsi flap. CONCLUSIONS: The pedicled latissimus dorsi flap is a reliable option for large and complex soft tissue injuries around the elbow significantly larger than previous reports. However, coverage of the proximal forearm remains challenging.
