title: Shoulder reconstruction after tumor resection by pedicled scapular crest graft.
abstract: The current authors present and evaluate a technique for reconstructing proximal humeral defects that result after resection of malignant bone tumors. Sixteen patients were included in this study with an average followup of 3 years (range, 12-76 months). Twelve patients had intraarticular resections, two had extraarticular resections, and two had intercalary resections. Reconstruction was done at the lateral border of the scapula (based on the circumflex scapular vessels) that was osteotomized and mobilized to bridge the resultant defect. Shoulder arthrodesis was done in 14 patients and the shoulder was spared in the two patients who had intercalary resections. Function was evaluated according to the Musculoskeletal Tumor Society scoring system. The average time for union of the graft proximally and distally was 6 months after which the graft started to hypertrophy. The average functional score was 22.5 points (75%) with a minimum score of 18 points (60%) and a maximum score of 27 points (90%). Nonunion of the distal host-graft junction occurred in two patients; both patients required iliac crest bone grafting and both achieved clinical and radiographic union without additional intervention. In three patients, the proximal fixation became loose but had no effect on function. The authors conclude that this technique is inexpensive, effective, and a durable reconstructive option for proximal humeral defects that are less than 15 cm. It has a predictable functional outcome (60%-90%) that is comparable with other reconstructive options.
