ABSTRACT
PURPOSE: To evaluate the functional outcomes of arthroscopic onlay dynamic anterior stabilization (DAS) using the long head of the biceps (LHB) tendon for treatment of anterior glenohumeral instability (AGI) with limited to subcritical glenoid bone loss (GBL).
METHODS: Twenty-five patients underwent arthroscopic DAS using LHB tendon between March 2022 and October 2022 for treatment of anterior glenohumeral instability (AGI) with limited to subcritical glenoid bone loss (GBL) were included in a prospective study with a minimum follow-up period of 2 years. The shoulder functional outcomes were assessed using the Rowe and the Quick Disabilities of Arm, Shoulder and Hand (Quick DASH) scores both preoperative and at 2 years follow-up. Magnetic resonance imaging (MRI) was done 6 months after surgery to evaluate LHB tendon healing to the anterior glenoid.
RESULTS: The study included 25 patients complaining of recurrent AGI. Twenty-one patients were males and four patients were females. The mean age of the patients at surgery was 22.75 ± 3.24 years. The mean duration between the first shoulder dislocation episode and surgery was 5.5 ± 2.13 months. The right shoulder was injured in 15 patients while the left shoulder was involved in 10 patients. The mean follow-up period was 24.25 ± 0.82 months. DAS using the long head of the biceps tendon resulted in a statistically significant improvement of the mean Rowe and the Quick DASH scores between preoperative and 2 years postoperative. Recurrent dislocation was reported in two (8%) patients during the follow-up period.
CONCLUSION: Arthroscopic onlay dynamic anterior stabilization using the long head of the biceps tendon is a safe and effective method for the treatment of recurrent anterior shoulder instability with GBL up to 25%.
LEVEL OF EVIDENCE: Level IV, case series study.
