PURPOSE: To report on the use of the Ligament Advanced Reinforcement System (LARS) to enhance joint stability and functional outcome in proximal humeral endoprosthesis reconstruction.
METHODS: Two men and 5 women aged 16 to 66 (mean, 28) years underwent wide resection of tumour and endoprosthesis reconstruction of the proximal humerus using the LARS, as the rotator cuff and/or deltoid muscle could be preserved. The preserved muscles were reattached to anatomic positions to regain function. Shoulder range of motion and Musculoskeletal Tumour Society scores were evaluated.
RESULTS: The mean follow-up was 26 (range, 14-36) months. All the 7 patients were alive without disease. The mean active abduction was 77º (range, 60°-100°), and the mean active flexion was 74° (range, 50°-100°). The mean Musculoskeletal Tumour Society score was 86% (range, 80-93%). One patient had instability of the glenohumeral joint at one year.
CONCLUSION: The LARS may enhance soft-tissue reattachment and improve shoulder stability after proximal humeral endoprosthetic reconstruction.
