Arthroscopic fixation with suture-bridge technique for greater tuberosity fractures / 中华骨科杂志

ABSTRACT

Objective To evaluate the outcome of arthroscopic fixation with suture-bridge technique for greater tuberosity fractures.Methods Between September 2014 to April 2016,data of 20 cases with greater tuberosity fractures who were treated with arthroscopic suture-bridge technique were retrospectively analyzed.There were 12 males and 8 females,with an average age of 51.2 years old (range,28-76 years).The average period from injury to surgery was 6 days (range,2-18 days).The postoperative X-ray of shoulder was collected.The active mobilization and strength rehabilitation were gradually introduced depended on patients' status.The preoperative and postoperative shoulder function were evaluated by Constant-Murley score,American Shoulder & Elbow Surgeons (ASES) score,visual analogue scale (VAS) pain score and UCLA score.Results All 20 patients were followed up for 15 months (range,12-30 months).There was no postoperative complication,including re-fracture,re-displacement,implant failure and wound infection.Shoulder joint activity at the last follow-uplift on the proneness of motion 168°±7.54° (range,150°-180°),outer spin 65.5°±6.71° (range,50°-70°),and internal rotation averaged T6 (range,T4-T10).At the last follow-up,the mean Constant-Murley score was 93.50±3.24,mean ASES score 90.80±4.72,mean VAS pain score 0.30±0.57 and mean UCLA score was 32.40±1.90.At the last follow-up,the anterior flexion in the side of the shoulder joint,the external rotation and internal rota tion were compared with the healthy side,and no statistical difference was found,and the function of the shoulder joint was satisfactory.There were two cases of Bankart injury,and the Bankart restoration was fixed by the arthroscope.Conclusion The arthroscopic suture-bridge technique can achieve less trauma,more reliable fixation for fractures of greater tuberosity of humerus.The arthroscopic suture-bridge technique can effectively spread the shear force and torsion force,increase the fixed area,and promote fracture healing.The arthroscopic fixation with suture-bridge technique is an effective treatment for fractures of greater tuberosity of humerus.
