Mid-term effectiveness of arthroscopic Bankart repair in treatment of recurrent anterior shoulder dislocation / 中国修复重建外科杂志

OBJECTIVE@#To investigate the mid-term effectiveness of arthroscopic Bankart repair for recurrent anterior shoulder dislocation.@*METHODS@#The clinical data of 107 patients with recurrent anterior shoulder dislocation who met the inclusion criteria between January 2017 and June 2021 was retrospectively analyzed, and all patients underwent arthroscopic Bankart repair. There were 88 males and 19 females. The age of the primary dislocation ranged from 13 to 48 years (mean, 23.3 years). The number of preoperative dislocations was 2-160 times (median, 7 times). The duration of preoperative instability was 0.2-240.0 months (median, 36.0 months). The mean age at operation was 28.2 years (range, 16-61 years). There were 43 cases of left shoulder and 64 cases of right shoulder. The proportion of glenoid defects in 63 patients was 1.7%-16.1% (mean, 8.1%). MRI showed that none of the patients had rotator cuff tears or shoulder stiffness. The CT three-dimensional reconstruction was performed at 1 day after operation to evaluate the distribution of implanted anchors and the occurrence of glenoid split fracture and whether there were nails pullout at the implant site. The postoperative complications were observed, and the pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, Rowe score, Constant-Murley score, and American Shoulder and Elbow Surgeons (ASES) score. The recurrence of instability, the results of apprehension test, the number of patients who returned to preoperative sports level, and the satisfaction rate of patients were recorded.@*RESULTS@#All patients were successfully operated and were followed up 20-73 months (mean, 41.5 months). All incisions healed by first intention. The CT three-dimensional reconstruction at 1 day after operation showed that the anchors were located at the 2 : 00-5 : 30 positions of the glenoid, and there was no glenoid split fracture or nails pullout at the implant site. At last follow-up, VAS score was significantly lower than that before operation, and Rowe score, Constant-Murley score, and ASES score were significantly higher than those before operation ( P<0.05). Seven patients (6.5%) had recurrence of anterior shoulder dislocation at 23-55 months (mean, 39.9 months) after operation, including 6 cases of dislocation and 1 case of subluxation. At last follow-up, 51 patients (47.7%) returned to preoperative sports level, and 11 patients (10.3%) had a positive apprehension test. The patients' satisfaction rate was 90.7% (97/107). Among the 10 patients who were not satisfied with the surgical effectiveness, 7 patients had postoperative recurrence of instability, and 3 patients felt that they did not return to preoperative sports level.@*CONCLUSION@#Arthroscopic Bankart repair has good mid-term effectiveness in patients with recurrent anterior shoulder dislocations, minimal or no glenohumeral bone defects and low sports need.

Clinical application of Fastpass Scorpion suture passer for arthroscopic Bankart repair / 中国修复重建外科杂志

OBJECTIVE@#To explore the effectiveness and advantages of using Fastpass Scorpion suture passer to stitch the inferior capsulolabral complex in arthroscopic Bankart repair compared with traditional arthroscopic suture shuttle.@*METHODS@#The clinical data of 41 patients with Bankart lesion, who met the selection criteria and were admitted between August 2019 and October 2021, was retrospectively analyzed. Under arthroscopy, the inferior capsulolabral complex was stitched with Fastpass Scorpion suture passer in 27 patients (FS group) and with arthroscopic suture shuttle in 14 patients (ASS group). There was no significant difference between the two groups ( P>0.05) in gender, age, injured side, frequency of shoulder dislocation, time from first dislocation to operation, and preoperative Rowe score of shoulder. Taking successful suture and pull-tightening as the criteria for completion of repair, the number of patients that were repaired at 5∶00 to 6∶00 (<6:00) and 6∶00 to 7∶00 positions of the glenoid in the two groups was compared. The operation time, and the difference of Rowe shoulder score betwee pre- and post-operation, the occurrence of shoulder joint dislocation, the results of apprehension test, and the constituent ratio of recovery to the pre-injury movement level between the two groups at 1 year after operation.@*RESULTS@#Both groups completed the repair at 5∶00 to 6∶00 (<6∶00), and the constituent ratio of patients completed at 6∶00 to 7∶00 was significantly greater in the FS group than in the ASS group ( P<0.05). The operation time was significantly shorter in the FS group than in the ASS group ( P<0.05). All incisions in the two groups healed by first intention. All patients were followed up 12-36 months (mean, 19.1 months). No anchor displacement or neurovascular injury occurred during follow-up. Rowe score of shoulder in the two groups significantly improved at 1 year after operation than preoperative scores ( P<0.05), and there was no significant difference in the difference of Rowe shoulder score between pre- and post-operation between the two groups ( P>0.05). At 1 year after operation, no re-dislocation occurred, and there was no significant difference in the apprehension test and the constituent ratio of recovery to the pre-injury movement level between the two groups ( P>0.05).@*CONCLUSION@#Compared with the arthroscopic suture shuttle, using Fastpass Scorpion suture passer to stitch the inferior capsulolabral complex in arthroscopic Bankart repair is more convenient, saves operation time, and has good effectiveness.

Latarjet procedure for failed arthroscopic Bankart repair: a case report

Arthroscopic Bankart Repair (ABR) provides acceptable results for recurrent anterior shoulder dislocation. However, recent studies have shown recurrent rates of 4-19% or even up to 35-40% in patients aged <25 years, and the results tend to get worse after long-term follow-up. The Latarjet procedure can improve anterior stability by multiple mechanisms, not only can the Bankart lesion be repaired and provide stability, but the transfer of the coracoid process extends the bony articular arc of the glenoid, and the addition of the conjoint tendon may provide dynamic stability as well. The Latarjet procedure for correcting recurrent anterior shoulder dislocation led to good and excellent results in 82.7% of the cases. The Latarjet procedure had the lowest re-dislocation rate, which was significantly lower than the arthroscopic Bankart repair. Latarjet procedure is effective in terms of restoring anteroinferior glenohumeral stability and good option for failed arthroscopic Bankart repair. Recurrence rates of instability are acceptable and re-operation rates were low.

Anterior Shoulder Instability with Concomitant Superior Labrum from Anterior to Posterior (SLAP) Lesion Compared to Anterior Instability without SLAP Lesion

BACKGROUND: The aims of this study were to investigate the clinical characteristics of patients with combined anterior instability and superior labrum from anterior to posterior (SLAP) lesions, and to analyze the effect of concomitant SLAP repair on surgical outcomes. METHODS: We retrospectively reviewed patients who underwent arthroscopic stabilization for anterior shoulder instability between January 2004 and March 2013. A total of 120 patients were available for at least 1-year follow-up. Forty-four patients with reparable concomitant detached SLAP lesions (group I) underwent combined SLAP and anterior stabilization, and 76 patients without SLAP lesions (group II) underwent anterior stabilization alone. Patient characteristics, preoperative and postoperative pain scores, Rowe scores, and shoulder ranges of motion were compared between the 2 groups. RESULTS: Patients in group I had higher incidences of high-energy trauma (p = 0.03), worse preoperative pain visual analogue scale (VAS) (p = 0.02), and Rowe scores (p = 0.04). The postoperative pain VAS and Rowe scores improved equally in both groups without significant differences. Limitation in postoperative range of motion was similar between the groups (all p-value > 0.05). CONCLUSIONS: Anterior instability with SLAP lesion may not be related to frequent episodes of dislocation but rather to a high-energy trauma. SLAP fixation with anterior stabilization procedures did not lead to poor functional outcomes if appropriate surgical techniques were followed.

Arthroscopic Bankart Repair for Post-seizure Anterior Instabilities of Shoulder : 2 Cases Report

PURPOSE: These case reports have been prepared to highlight the uncommon occurrence of anterior shoulder dislocation after an epileptic seizure, the recognition of which is important as this type of injury is associated with bony lesions and a high incidence of recurrence. MATERIALS AND METHODS: We report two cases of recurrent anterior dislocation of the shoulder due to grand mal epilepsy. These cases were treated as usual anterior dislocations of the shoulder, and were regularly followed to detect any recurrence of shoulder instability. RESULTS: Outcome of the surgery in the two cases was different because of the differences in seizure control. In the patient in whom seizures were well-controlled, there was no recurrence of instability, while the patient with poorly controlled seizures developed a recurrence of the dislocation following shoulder repair. CONCLUSION: The authors emphasize the need to control seizures in order to prevent injury recurrence in this subset of patients.

Brachial Plexus Injury as a Complication of Arthroscopic Bankart Repair: A Case Report / 대한정형외과학회잡지

Shoulder arthroscopy is widely used through the development of arthroscopic technique and equipment but some complications have been reported that are related to the complexity of technique and the long duration time of operation. Brachial plexus injury, as a complication of arthroscopic Bankart repair, is rare, but remains a serious sequelae. We performed the neurorrhaphy and neurolysis of brachial plexus and showed relatively good functional outcome after 2 years.

Outcomes after Arthroscopic Repair of Anterior Shoulder Instability after Metal Anchor to Biodegradable Anchor Fixation

PURPOSE: We compared the results of arthroscopic Bankart repair using metal and biodegradable anchor fixation. MATERIALS & METHODS: We reviewed 26 patients with anterior shoulder instability treated by arthroscopic Bankart repair from October, 2006, to March, 2007, 15 patients with metal anchors and 11 patients with biodegradable anchors. The average age was 27.4 years old (range: 17~55) and mean follow-up was 14 months (range: 12~17 months). Functional outcome was evaluated using the Korean Shoulder Score for Instability (KSSI), Rowe's Bankart Grading scale (RBGS), ASES score, and UCLA scores. RESULTS: In the metal-anchor group, the improvements of mean KSSI, ASES, UCLA score, and RBGS were 20.6, 24.0, 4.0, and 45.5, respectively. In the biodegradable anchor group, improvements of mean KSSI, ASES, UCLA score, and RBGS were 21.0, 23.6, 4.6, and 48.9. The improvements in final outcomes were not significantly different (p>.05). One metal problem and one traumatic redislocation occurred in the metal group. CONCLUSION: Both techniques produced satisfactory outcomes in the treatment of traumatic anterior instability. The biodegradable anchor group could also avoid problems with metal anchors.

Result of Early Active Range of Motion Exercise after Bankart Repair of Traumatic Anterior Instability

PURPOSE: To evaluate prospectively the results of early active exercise after open Bankart repair of traumatic anterior shoulder instability. MATERIALS AND METHODS: From January, 2001 to June, 2003, 26 patients who were followed up at least 1 year after open Bankart repair for traumatic anterior shoulder instability were evaluated. Average age was 23.9 years old (range, 19~43) with 24 males and 2 females. We evaluated them using the functional shoulder scores (modified Rowe score, ASES score), range of motion, VAS pain scale, patient's subjective satisfaction and return to unlimited daily living activity. RESULTS: The shoulder functional scores increased significantly. At last follow up, the final range of motion were flexion in average 5° deficit in comparison to normal side, external rotation in average 10o deficit, and internal rotation in T9. The patient's subjective satisfaction was good in 2l patients (81%). Return to unlimited daily activity was possible in 23 patients (88.5%), and 19 patients (73%) rejoined to sports activity before injury. There were complications including anterior recurrent subluxation in 1 case, weakness of subscapularis muscle in 1 case. CONCLUSION: In traumatic anterior shoulder instability, early active range of motion exercise after open Bankart repair does not decrease shoulder stability. Early exercise can be useful for returning to previous level of sports activity in young active patients.

Bankart Repair for the Traumatic Anterior Shoulder Instability : At Least 6 Years Follow-up / 대한정형외과학회잡지

PURPOSE: This study compared the long-term clinical results of an open Bankart procedure for anterior shoulder instability with those from an arthroscopic procedure, and evaluated the factors influencing the final outcomes and recurrence. MATERIALS AND METHODS: One hundred thirty three shoulders with a Bankart repair of a traumatic anterior shoulder instability with a follow-up period of at least 6 years were enrolled in this study. Sixty-seven shoulders had an open repair and sixty-six shoulders, an arthroscopic repair. The mean age at the time of the operation was 27.7 years (range, 17 to 62 years). The mean follow-up period was 100 months (range, 72 to 141 months). RESULTS: At the last follow-up, the pain score during motion improved from 3.86 to 1.36. Forward flexion and external rotation at the side decreased to a mean of 3 degrees, 9 degrees in the open group and a mean of 1 degree, 4 degrees in the arthroscopic group. Sixty-two (93%) and 59 shoulders (89%) in the open and arthroscopic group could return to their pre-injury sports activities, respectively. At a mean 12.5 months after surgery, 14 shoulders (10.5%) experienced a redislocation. There were 6 (9%) and 8 (12%) redislocations in the open and arthroscopic groups, respectively. CONCLUSION: The open group showed relatively better results than the arthroscopic group but there was no significant difference between two groups. Both open and arthroscopic Bankart procedures are effective methods that produce acceptable results when a precise surgical technique and proper postoperative rehabilitation are carried out.

The Effect of Arm Position on the Repaired Capsulolabrum after Arthroscopic Bankart Repair: Magnetic Resonance Imaging Study / 대한정형외과학회잡지

PURPOSE: To evaluate and describe the findings of immediate postoperative, magnetic resonance (MR) arthrography of repaired capsulolabrum using two different arm positions (internal rotation and external rotation) for patients who had undergone arthroscopic Bankart repair. MATERIALS AND METHODS: Arthroscopically-repaired Bankart lesions were examined in the axial T2-weighted images of MR-arthrogram in twenty-two shoulders on the immediate postoperative day. We measured three parameters (height, slope, and medial overhang) on the axial images at the anteroinferior portion of the glenoid in internal and external rotation of the adducted arm. The mean internal rotation of the arm was 30degrees (range, 14degrees to 45degrees) and the mean external rotation was 19degrees (range, 2degrees to 44degrees). The two heights and slopes were compared using the paired t-test. For medial overhang, crosstable McNemar test was used. Statistical analyses were performed with the SPSS software package. RESULTS: There were 21 male and 1 female patients with a mean age of 24 years (range, 17 to 36 years). The arms in internal rotation position showed a loss of capsulolabral buttress in all patients. When the arm was in external rotation, the height and slope of the labrum were both greater, being on average 1.47 mm and 7degrees, respectively (p<0.001 for both measures), than those in the internal rotation position. Medial overhang on the glenoid rim was 81% positive when the arm was in the internal rotation position but 86% negative with the arm externally rotated (p<0.001). CONCLUSION: Loss of repaired capsulolabral buttress seems to be inevitable when the arm is immobilized in the internal rotation position after arthroscopic Bankart repair. To prevent this, we recommend immobilization of the arm in external rotation after the surgery.

Capsular Imbrication and Bankart Repair in Traumatic Anterior Shoulder Instability : Effect of Subscapularis Tendon Division on Internal Rotator Strength and Shoulder Function / 대한정형외과학회잡지

PURPOSE: To evaluate the function of the shoulder and the effect of the division of the subscapularis tendon on the strength of the inter-nal rotator after capsular imbrication and Bankart repair. MATERIALS AND METHODS: From January, 1996 to December, 2000, we reviewed thirty cases of traumatic anterior shoulder instability, which underwent capsular imbrication and Bankart repair. The follow up period was minimally one year. The clinical results were evaluated using the ASES (American Shoulder and Elbow Surgeons) score and the muscle power of the internal rotator as measured by a myometer. RESULTS: All cases showed satisfactory results; nineteen cases (63%) were excellent, and eleven cases (37%) were good. Mean value of ASES score increased from 78.6 (60-82) ponts to 94.5 (84-100) points. Mean value of the score increased was 16 (14-38) points. Postoperatively, the muscle power of the internal rotator compared with contralateral was increased in 12 cases (40%), decreased in 17 cases (57%), and was the same in one case (3%). There was no cases of deterioration of function, recurrence or requiring revision surgery. CONCLUSION: In capsular imbrication and Bankart repair, the division of the subscapularis tendon did not produce a significant adverse effect in the strength of the internal rotator. We believe that this is one of the useful treatment methods in traumatic anterior shoulder insta-bility, because it provides stability and a good range of motion.
