IntroductionRotator cuff tears (rct) subsequent to glenohumeral dislocation are relevant concomitant injuries, can lead to impaired shoulder function and increase risk of recurrent dislocation.AimThe aim of this study was to determine the functional outcome, recurrent dislocation rate and tendon integrity after rotator cuff repair after primary traumatic shoulder dislocation.Materials And MethodsIn this retrospective case series, 23 patients (age 56.4 years ± 6.3) who underwent a rotator cuff reconstruction after primary traumatic shoulder dislocation with confirmed combination of full-thickness RCT and Bankart lesion were enrolled after a minimum follow-up of 2 years. Clinical outcome (age and gender adjusted Constant Murley Score (CMS), DASH, Rowe Score) (n = 23) and sonographic tendon integrity (n = 19) were studied.ResultsAfter a mean follow-up of 58 ± 32 months, a CMS of 85.1% ± 14.7, DASH of 14.2 ± 20.5, and Rowe Score of 82.4 ± 15.2 indicated good functional outcome. In 4 of 19 patients (21.1%) a re-tear was found during sonographic evaluation. In 3 cases (13%), a revision was performed (2 × stiff shoulder, 1 × postoperative infection). One patient had a single traumatic re-dislocation (4.3%).ConclusionsPatients undergone reconstruction of the rotator cuff following a primary traumatic shoulder dislocation can achieve good functional results and a low rate of recurrent dislocation. Postoperative tendon integrity is comparable with known data about non traumatic tears.
