Abstract:
Background: Anterior recurrent instability of the glenohumeral joint is a common clinical problem among 3 the young population. Glenoid reconstruction with bone graft has become the treatment of choice, 4 particularly in significant deficiency (˃ 20%). This study aims to assess the functional results of glenoid 5 reconstruction using Latarjet and iliac bone graft in management of glenoid insufficiency associated with 6 recurrent anterior dislocation of the glenohumeral joint. 7 Methods: Patients suffering from anterior shoulder instability with glenoid defect > 20% were included in 8 this study between 2016 and 2021. University of California at Los Angeles (UCLA) shoulder scale and 9 Constant score were used to assess the functional improvement. Preoperative and final postoperative 10 continuous outcomes were compared with one-tailed paired t-test and the outcomes across groups were 11 compared using two-tailed independent t- test. P-value of < 0.05 was considered statistically significant for 12 both tests. 13 Results: This trial included 50 patients; twenty-five underwent mini-open Latarjet, and 25 underwent 14 arthroscopic tricortical iliac bone grafting (ICBG). The mean follow-up durations were 50.1 ± 5.9 months 15 for Laterjet and 51.6 ± 6.8 months for ICBG. Both techniques showed statistically significant improvement 16 in the final UCLA (31.1± 2.1 in Laterjet, and 30.2± 2.2 in ICBG) and Constant (90.2± 4.6 in Laterjet, and 17 89± 5.01 in ICBG) scores. There was no statistically significant difference regarding mean age, sex, side 18 of injury, mechanism of injury, follow-up period, and clinical outcome between both surgical treatments. 19 At the end of the study, both groups demonstrated statistically significant improvement in the range of 20 motion (p˂ 0.00001). Only one, non-adherent patient in Laterjet group had post-operative dislocation. In 21 ICBG group, two patients had partial bone graft resorption, 3 graft site morbidities, and 1 hardware 22 prominence.
