Abstract:
Objective:To investigate the clinical results of arthroscopic double-pulley double row suture technique for the treatment of bigger Ideberg Ia glenoid fracture.
Methods:From January 2014 to July 2017, data of patients with Ideberg Ia glenoid fracture who were treated by arthroscopic double-pulley double row suture technique were retrospectively analyzed. Totally 24 patients were enrolled of whom 13 were males and 11 were females. The mean age was 50.14±10.60 years (range, 34-67). In those patients, there were 8 cases of glenoid fracture alone, 4 cases of glenoid fracture associated with greater tuberosity fracture, 5 cases of glenoid fracture with rotator cuff tear, 4 cases of glenoid fracture with shoulder anterior dislocation and greater tuberosity fracture, 2 cases of glenoid fracture with shoulder anterior dislocation and rotator cuff tear, and 1 case of shoulder anterior dislocation with ipsilateral distal radius fracture. The fragment accounts for 28.91±5.35% (range, 25.1%-38.5%) of the glenoid articular surface. According to the size of the fragment, one medial row anchor was used to implant at the medial edge of the fracture bed of the anterior edge of the glenoid; two to four lateral row suture anchors were used to implant at the margin of the glenoid joint surface sequentially from low level to higher level, and simplified double-pulley technique was finally used to fix the fragment. The situation of fracture reduction and healing and the post-operative complications were evaluated. The Constant-Murley, DASH and VAS were also recorded.
Results:Satisfactory fracture reduction and fixation were achieved in all 24 patients. The mean follow-up time was 19.5 months (range, 12-36). Mean VAS was 0.8±0.8 (range, 0-2). The range of motion at the latest follow-up was: anterior flexion 145°-180° (mean, 161.00°±5.77°), external rotation at the side 35°-60° (mean, 46.43°±6.63°), internal rotation L3-T10 level. The mean Constant-Murley score was 88.1±3.7 (range, 81-93), and mean DASH score was 8.4±4.7 (range, 0-40.4). All cases except one showed no dislocation or disability of the shoulder. The CT scans showed: 19 cases of which the step-off of articular surface was less than 2 mm; 4 cases of which the step-off was between 2 mm to 4 mm and 1 case of which the step-off was more than 4 mm. No severe osteoarthritis was identified at the latest follow-up, and only 1 patient at the age of 67 showed slight osteoarthritis. Two patients with shoulder anterior dislocation and rotator cuff tear committed significant restricted shoulder range of motion.
Conclusion:The arthroscopic simplified double-pulley double row suture technique was identified safe, effective and reliable for treating the bigger Ideberg Ia glenoid fracture. The technique is able to provide clear visulization of the fracture and achieve excellent clinical results.
