Novel Use of Calcium Phosphate Bone Void Filler in Rotator Cuff and Labral Repair

Patients with poor bone quality or cystic changes present a unique problem when utilizing standard arthroscopic rotator cuff and labral repair techniques and implants. Previous studies have looked at multiple methods to augment the bone in the presence of poor bone quality to allow for appropriate fixation with variable success. The following case reports describe the use of AccuFill, an injectable calcium phosphate bone void filler, to augment rotator cuff or labral repair in the setting of deficient bone in the greater tuberosity or glenoid. In the rotator cuff repair case report, follow-up imaging at 1 year show tendonhealing, radiographic resolution of the cyst, and the patient returned to full function without postoperative complications. In the deficient posterior glenoid bone stock case report the technique allowed robust posterior labral advancement and repair and solid purchase of suture anchors; with 1-year follow-up imaging showing no reformation of the cyst. In both cases, patients underwent the procedure without significant increase in operative time or technique difficulty.
