title: Arthroscopic fixation for displaced greater tuberosity fracture using the suture-bridge technique.
abstract: With the described technique, two bioabsorbable suture anchors are inserted to create a medial row through the intact cuff for fixation of the fragment of the greater tuberosity. The medial row is repaired with a sliding knot. After confirmation of the fracture site, pilot holes for a PushLock anchor (Arthrex, Naples, FL) are prepared directly in line with the medial anchors and approximately 5 to 10 mm distal to the lateral edge of the fragment of the greater tuberosity. A suture strand from each anchor in the medial row is retrieved. Both suture strands are threaded through the PushLock eyelet on the distal end of the driver. The anchor is advanced completely into the pilot hole. These steps are repeated for a second anchor. If a dog-ear deformity is observed at the margin after complete reduction of the greater tuberosity, a stitch is made by use of a suture hook and one strand of the uncut suture from the lateral row of the joint via the modified suture-bridge technique. Arthroscopic reduction and internal fixation of displaced greater tuberosity fractures with the suture-bridge technique described by us provide adequate fixation with improvement of the pressurized contact area of the fracture and can be used as an additional modality of arthroscopic treatment.
