Abstract
Anterior shoulder dislocation is the most common major joint dislocation. Historically many different techniques have been described for the treatment of anterior traumatic isolated shoulder instability and various rates of successful results have been given in the literatures.
Initial results of arthroscopic Bankart repair was satisfactory, but long term results showed relatively high recurrence rate. High risk patients for recurrence after arthroscopic Bankart repair are competitive sport participants, heavy manual workers, patients with controlled epileptic fits and tramadol addictive patients.
The aim of the study was to compare between open Laterjet procedure and arthroscopic Bankart repair for management of recurrent anterior shoulder dislocation as regard postoperative range of motion, functional scoring and recurrence.
This was a prospective study including thirty patients having post-traumatic anterior shoulder dislocation. Fifteen patients were managed by open Laterjet procedure and fifteen patients were managed by arthroscopic Bankart repair. This study was conducted in Mansoura University student hospital and Menoufia University hospital between August 2016 and January 2020. The mean age of patients at time of operative intervention was 23.6 ± 3.68 years in open group and 23.53 ± 3.6 in arthroscopic group. There was not statistically difference between UCLA sore, Constant score, return to preinjury level, degree of external rotation of the shoulder and redislocation.
However, there was significant reduction in postoperative hospital stay in arthroscopic group (1.20±0.41) days than open group (2.47±1.18) days. Degree of range of external rotation in abduction was in open group (70.73 ± 9.05) degrees and arthroscopic group (71.67 ± 4.08) degrees. Range of external rotation in adduction was in open group (36 ± 6.87) degrees and in arthroscopic group was (33 ± 4.55) degrees. Although positive postoperative apprehension test was found in one patient (6.7%) in open group and four patients (26.7%) in arthroscopic group. UCLA score in open group was (29.40±1.64) and in arthroscopic group was (28.73±1.67). Also Constant score in open group was (79.20 ± 4.55) and in arthroscopic was group (78.00 ± 5.29). Return to return to pre injury level of sport in open group was (7.67±1.39) months and in arthroscopic group was (8.07±1.77) months. Recurrence occurred in one patient in arthroscopic group (6.7%) 15 months after the operation as a result of new evident trauma. Two patients in arthroscopic group had transient postoperative neurapraxia. One patient in open group had superficial skin infection, which was managed by intravenous antibiotics only.
