Background:
Anterior recurrent instability of the glenohumeral joint is a common clinical problem among the young population. Glenoid reconstruction with bone graft has become the treatment of choice, particularly in significant deficiency (˃20%). This study aims to assess the functional results of glenoid reconstruction using Latarjet and iliac bone graft in the management of glenoid insufficiency associated with recurrent anterior dislocation of the glenohumeral joint.
Methods:
Patients suffering from anterior shoulder instability with glenoid defect >20% were included in this study between 2016 and 2021. The university of California at Los Angeles (UCLA) shoulder scale and Constant score were used to assess the functional improvement. Preoperative and final postoperative continuous outcomes were compared with a one-tailed paired t-test and the outcomes across groups were compared using a two-tailed independent t-test. A P-value of <0.05 was considered statistically significant for both tests.
Results:
This trial included 50 patients; twenty-five underwent mini-open Latarjet, and 25 underwent arthroscopic tricortical iliac crest bone grafting (ICBG). The mean follow-up durations were 50.1 ± 5.9 months for Laterjet and 51.6 ± 6.8 months for ICBG. Both techniques showed statistically significant improvement 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 89 ± 5.01 in ICBG) scores. There was no statistically significant difference regarding mean age, sex, side of injury, mechanism of injury, follow-up period and clinical outcome between both surgical treatments. At the end of the study, both groups demonstrated statistically significant improvement in the range of motion (p ˂ 0.00001). Only one, non-adherent patient in Laterjet group had post-operative dislocation. In ICBG group, two patients had partial bone graft resorption, 3 graft site morbidities and 1 hardware prominence.
Conclusion:
Both Laterjet and iliac bone graft procedures had satisfactory functional results in reconstruction of glenoid defect >20% in unstable shoulders with a mean 4-year follow-up. No statistically significant difference was reported in the last postoperative Constant and UCLA scores between both techniques, but Latarjet procedure had fewer complications (4%) than ICBG (24%).
Level Of Evidence:
Prospective non-randomized comparative study; level II.
