Abstract

Abstract:

Objective

To explore the effect of arthroscopic double-row anchor suture bridge fixation technique in the treatment of avulsion fracture of the humeral greater tuberosity.

Methods

Twenty-three patients who underwent arthroscopic double-row anchor suture bridge fixation in Nantong University Affiliated Jianhu Hospital from March 2013 to March 2017 were followed up. The displacement of humeral tuberosity fracture in these patients was more than 5 mm, and the area of fracture fragment was less than 3 cm ×3 cm. There was no other injury, such as rotator cuff injury, superior labrum anterior and posterior (SLAP)injury, or Bankart injury. Range of motion, visual analogue scale (VAS) score and American Shoulder and Elbow Surgeon (ASES) score were collected during the last follow-up. Paired sample t test or rank sum test was used to compare the data before and after operation.

Results

Bone healing was achieved in all the patients within three months. Shoulder flexion mobility increased from preoperative(92.4±15.3)° to postoperative (148.7±15.3)°(t=9.956, P<0.01). Abduction activity increased from preoperative (85.0±12.6)° to postoperative (147.3±14.4)°(t=15.502, P<0.01. External rotation activity increased from preoperative (21.5±10.2)° to postoperative (30.7±11.8)°(t =12.058, P<0.01). The VAS scores decreased compared to the preoperative ones (Z=4.107, P<0.01). ASES score increased from preoperative (29.7±6.1) to postoperative (91.8±4.1)(t =41.879, P<0.01).

Conclusion

Arthroscopic double-row anchor suture bridge technique is effective in the treatment of simple avulsion fracture of greater tubercle of humerus, with minimal trauma, rapid recovery and good functional recovery of shoulder joint.
