[Development and research progress of suture button fixation Latarjet procedure].

Objective: To review the development and research progress of suture button fixation Latarjet procedure. Methods: A comprehensive literature review was conducted to summarize the development and related modified techniques of the suture button fixation Latarjet procedure. Results: Since the Latarjet procedure was first introduced by French scholar Latarjet in 1954, it has undergone three key transformations, resulting in suture button fixation Latarjet procedure, which has shown satisfactory outcomes in treatment of recurrent shoulder dislocation. However, there are still drawbacks such as the risk of impingement of the graft on surrounding tissues, and the surgical disruption of anatomical structures like the coracoclavicular ligament and the pectoralis minor muscle. The scholars have proposed several modified techniques based on the suture button fixation Latarjet procedure to further reduce complications from impingement of the graft, to lower the glenohumeral contact pressure, and to eliminate the impact of surgery on the physiological structures of the shoulder joint. The modified techniques include the arthroscopic suture button fixation Latarjet procedure using FiberTape Cerclage, reconstruction of the coracoacromial ligament during congruent-arc Latarjet procedures, and limit unique coracoid osteotomy suture button Latarjet procedure (LU-tarjet procedure). These modified techniques have also shown good clinical outcomes. Additionally, other related modified techniques for reconstruction of the glenoid, such as Chinese unique Inlay Bristow procedure (Cuistow procedure), arthroscopic glenoid bone grafting with soft fixation, and all-arthroscopic modified Eden-Hybinette procedure, have also demonstrated favorable efficacy. However, there is still a lack of long-term follow-up results for these techniques and comparative studies between them. Conclusion: Suture button fixation Latarjet procedure is an effective method for the treatment of recurrent shoulder dislocation. There are various techniques, but there is no recognized gold standard, and further clinical and basic research is needed.

[Application of LU-tarjet congruent-arc technique in treatment of recurrent shoulder dislocation with huge glenoid defect].

Objective: To investigate the early effectiveness of the limited unique coracoid osteotomy suture button fixation Latarjet (LU-tarjet)-congruent-arc (CA) technique (LU-tarjet-CA) in treating recurrent shoulder dislocations with huge glenoid defect. Methods: The clinical data of 12 patients with recurrent shoulder dislocation and huge glenoid defect who met the selection criteria and treated with arthroscopic LU-tarjet-CA between January 2021 and December 2023 were retrospectively analyzed. The cohort included 8 males and 4 females, aged 20-40 years with an average age of 30.4 years. The range of glenoid bone loss was 30%-40%, with an average of 35.5%. The time from symptom onset to hospital admission ranged from 1 to 36 months, with an average of 18.5 months. The University of California Los Angeles (UCLA) score, American Association for Shoulder and Elbow Surgery (ASES) score, Walch-Duplay score, and Rowe score were used to evaluate shoulder function preoperatively and at 3, 6, and 12 months postoperatively. CT three-dimensional (3D) reconstruction was used to assess coracoid healing and plasticity at 3, 6, and 12 months postoperatively. Subjective satisfaction of patient was recorded at last follow-up. Results: All incisions healed by first intention, with no incision infection or nerve injury. All 12 patients were followed up 12 months. One patient developed Propionibacterium acnes infection within the joint postoperatively and recovered after initial arthroscopic debridement and anti-inflammatory treatment. At 3 months after operation, CT 3D-reconstruction showed 1 case of complete coracoid absorption; neither of these two patients experienced redislocation. The remaining patients exhibited partial coracoid absorption but displayed local reshaping, filling the preoperative defect area, and bony fusion between the coracoid and the glenoid. At last follow-up, 9 patients (75%) were very satisfied with the outcome, and 3 patients (25%) were satisfied; the satisfied patients experienced postoperative shoulder stiffness caused by suboptimal functional exercise but did not have impaired daily life activities. The UCLA score, ASES score, Walch-Duplay score, and Rowe score at 3, 6, and 12 months postoperatively were significantly better than preoperative scores, and each score improved further over time postoperatively, with significant differences between different time points ( P<0.05). Conclusion: The arthroscopic LU-tarjet-CA technique for treating recurrent shoulder dislocations with huge glenoid defect can achieve the surgical objective of bony blockade and filling bone defects to prevent shoulder dislocation, thereby improving patients' quality of life and shoulder joint function and stability.

[Surgical accidents and postoperative complications of recurrent shoulder dislocation treated by suture button fixation with bone occlusion].

Objective: To summarize the surgical accidents and postoperative complications of the treatment of recurrent shoulder dislocation by suture button fixation and bone occlusion, and to provide clinical reference. Methods: The clinical data of 16 patients with recurrent shoulder dislocation treated with modified arthroscopic Latarjet suture button fixation and bone occlusion between July 2017 and April 2023 were retrospectively analyzed. Among them, 15 were male and 1 was female. The age ranged from 16 to 45 years, with an average of 26 years. Admission examination showed the range of motion of shoulder joint was normal; the shoulder joint fear test was positive; En-face CT scan measured 10%-20% of the glenoid defects, averaging 13.4%; and MRI examination revealed bone Bankart injury. The disease duration ranged from 2 to 20 years, with an average of 7.1 years. The shoulder joint was dislocated 8- 45 times, with an average of 17.4 times, and the shoulder joint was unstable. The occurrence of surgical accidents and postoperative complications as well as corresponding measures and outcomes were recorded. Results: All the incisions healed by first intention without any complications such as incision infection or vascular injury. All 16 cases were followed up for an average of 3.6 years (range, 1-7 years), and no shoulder redislocation occurred. Four types of intraoperative surgical accidents and two types of postoperative complications occurred in the early stage of implementation of the technique. Intraoperative surgical accidents included 1 case of difficulty in passing subscapular muscle through coracotomy with large size, which was treated with exchange rod or finger through subscapular muscle split; 2 cases of coracoidal process fracture, of which 1 case was treated conservatively, and the other case was sutured to the base of tendon and fixed through tunnel; 1 case of glenoid fracture occurred in the glenoid tunnel, which was fixed with knot-free anchors; the posterior loop plate fixation was abnormal in 2 cases, of which 1 case was re-fixed and the other case was renovated. Postoperative complications included coracoid bone mass displacement in 1 case, conservative biceps rehabilitation was given to avoid premature external rotation; 1 case of radial nerve injury of healthy upper limb and musculocutaneous nerve injury of affected side was given oral medication and physiotherapy. The above conditions recovered well after corresponding treatment. Conclusion: Suture button fixation with bone occlusion is a safe method for the treatment of recurrent shoulder dislocation. Careful operation should be performed during coracoid interception and glenoid tunnel drilling, especially in the fixation process.

Serial Magnetic Resonance Arthrography for a Midsubstance Capsular Tear in a Patient With Traumatic Anterior Shoulder Instability.

The natural history of midsubstance capsular tears (MCTs) is unclear. We herein describe a case of MCT observed using serial magnetic resonance (MR) arthrography. A 46-year-old woman presented with excessive external rotation of the left glenohumeral joint, resulting in an initial anterior dislocation of the left shoulder. She subsequently developed recurrent shoulder joint dislocations. MR arthrography revealed an MCT without a Bankart lesion three months after the initial dislocation. She opted for nonoperative treatment, but the shoulder instability did not improve. The second MR arthrography, nine months after the initial dislocation, showed no natural healing of the MCT. The third MR arthrography, 12 months after the initial dislocation, also showed no natural healing. Her shoulder instability remained persistent. The patient then decided to have surgery. Arthroscopy revealed a large capsular defect extending from the glenoid to the humeral head in the anterior inferior glenohumeral ligamentous complex. The MCT was repaired with the placement of nonabsorbable sutures in a side-to-side fashion. At the final follow-up, three years postoperatively, the patient had no anterior shoulder instability. The Rowe score was 100 points. MR arthrography showed good repair integrity of the MCT at one year postoperatively. Serial MR arthrography was useful for both the patient and the shoulder surgeon in considering the treatment of the MCT, facilitating an accurate and qualitative assessment of whether natural healing of the MCT had been achieved.

Comparison of the Latarjet Procedure With the Modified Putti-Platt Surgery for Recurrent Anterior Shoulder Dislocation With Respect to Functional Outcome.

Introduction Shoulder dislocation is the most common injury encountered in orthopedic outpatient department. The choice of procedure depends on the expertise of surgeons. The objective of this study was to compare the Latarjet procedure with the modified Putti-Platt surgery for recurrent anterior shoulder dislocation in terms of functional outcomes. Materials and methods A quasi-experimental study evaluated 60 patients with recurrent anterior shoulder instability. Patients were assigned to either Latarjet or modified Putti-Platt surgery. Functional outcomes were assessed at six months using the Constant-Murley shoulder score. Results This study encompassed 60 patients (mean age: 23.93±5.88 years) undergoing shoulder procedures. Functional outcomes exhibited a majority of 55% excellent, 35% good, 6.7% fair, and 3.3% poor outcomes. No significant differences in functional outcomes were found between the procedures. Conclusion Both procedures may be viable options for recurrent shoulder instability. The choice may depend on patient factors and surgeon preference. Further research is needed to refine techniques and identify ideal candidates.

Arthroscopic stabilization surgery for first-time anterior shoulder dislocations: a systematic review and meta-analysis.

BACKGROUND: The optimal management of first-time anterior shoulder dislocations (FTASDs) remains controversial. Therefore, the purpose of this study was to assess the efficacy of arthroscopic stabilization surgery for FTASDs through a systematic review and meta-analysis of existing literature. METHODS: MEDLINE, Embase, and Web of Science were searched from inception to December 18, 2022, for single-arm or comparative studies assessing FTASDs managed with arthroscopic stabilization surgery following first-time dislocation. Eligible comparative studies included studies assessing outcomes following immobilization for an FTASD, or arthroscopic stabilization following recurrent dislocations. Eligible levels of evidence were I to IV. Primary outcomes included rates of shoulder redislocations, cumulative shoulder instability, and subsequent shoulder stabilization surgery. RESULTS: Thirty-four studies with 2222 shoulder dislocations were included. Of these, 5 studies (n = 408 shoulders) were randomized trials comparing immobilization to arthroscopic Bankart repair (ABR) after a first dislocation. Another 16 studies were nonrandomized comparative studies assessing arthroscopic Bankart repair following first-time dislocation (ABR-F) to either immobilization (studies = 8, n = 399 shoulders) or arthroscopic Bankart repair following recurrent dislocations (ABR-R) (studies = 8, n = 943 shoulder). Mean follow-up was 59.4 ± 39.2 months across all studies. Cumulative loss to follow-up was 4.7% (range, 0%-32.7%). A composite rate of pooled redislocation, cumulative instability, and reoperations across ABR-F studies was 6.8%, 11.2%, and 6.1%, respectively. Meta-analysis found statistically significant reductions in rates of redislocation (odds ratio [OR] 0.09, 95% confidence interval [CI] 0.04-0.3, P < .001), cumulative instability (OR 0.05, 95% CI 0.03-0.08, P < .001), and subsequent surgery (OR 0.08, 95% CI 0.04-0.15, P < .001) when comparing ABR-F to immobilization. Rates of cumulative instability (OR 0.32, 95% CI 0.22-0.47, P < .001) and subsequent surgery rates (OR 0.27, 95% CI 0.09-0.76, P = .01) were significantly reduced with ABR-F relative to ABR-R, with point estimate of effect favoring ABR-F for shoulder redislocation rates (OR 0.59, 95% CI 0.19-1.83, P = .36). Return to sport rates to preoperative levels or higher were 3.87 times higher following ABR-F compared to immobilization (95% CI 1.57-9.52, P < .001), with limited ABR-R studies reporting this outcome. The median fragility index of the 5 included randomized controlled trials (RCTs) was 2, meaning reversing only 2 outcome events rendered the trials' findings no longer statistically significant. CONCLUSION: Arthroscopic stabilization surgery for FTASDs leads to lower rates of redislocations, cumulative instability, and subsequent stabilization surgery relative to immobilization or arthroscopic stabilization surgery following recurrence. Although a limited number of RCTs have been published on the subject matter to date, the strength of their conclusions is limited by a small sample size and statistically fragile results.

Reconstruction of recurrent shoulder dislocation with glenoid bone defect with 3D-printed titanium alloy pad: outcomes at 2-year minimum follow-up.

BACKGROUND: To evaluate the outcome of shoulder arthroscopy-assisted implantation of three-dimensional (3D)-printed titanium pads for recurrent shoulder dislocation with glenoid bone defects. METHODS: From June 2019 to May 2020, the clinical efficacy of 3D printed titanium pad implantation assisted by shoulder arthroscopy, for the treatment of recurrent shoulder dislocations with shoulder glenoid defects was retrospectively analyzed. The American Shoulder and Elbow Surgeons (ASES) shoulder, Rowe, and Constant scores were recorded before surgery and at 3 months, 6 months, 1 year, and 2 years after surgery. 3D computed tomography (CT) and magnetic resonance imaging were used to evaluate the location of the glenoid pad, bone ingrowth, joint degeneration, and osteochondral damage. RESULTS: The mean age of the 12 patients was 21.4 (19-24) years and the mean follow-up time was 27.6 (24-35) months. The Visual Analog Scale score significantly improved from 5.67 ± 1.98 preoperatively to 0.83 ± 0.58 postoperatively (p = 0.012). The postoperative ASES score was significantly increased to 87.91 ± 3.47 compared with preoperative ASES score (46.79 ± 6.45) (p < 0.01). Rowe and Constant scores also improved from 22.5 ± 12.34 and 56.58 ± 7.59 preoperatively to 90.83 ± 4.69 and 90.17 ± 1.89 at 2 years postoperatively, respectively. CT performed 2 years after surgery showed that the pad perfectly replenished the bone-defective part of the shoulder glenoid and restored the articular surface curvature of the shoulder glenoid in the anterior-posterior direction, and the bone around the central riser of the pad was tightly united. Magnetic resonance imaging 2 years after surgery showed that the humeral head osteochondral bone was intact, and there was no obvious osteochondral damage. CONCLUSIONS: 3D printed titanium pads are a reliable, safe, and effective surgical procedure for treating recurrent shoulder dislocations with glenoid bone defects.

Comparison of Glenohumeral Bone Morphology Between Patients With Versus Without Anterior Shoulder Instability.

Background: The stability of the glenohumeral joint is associated with anatomic characteristics including bony structures and soft tissues. Purpose: To compare the differences in specific bony glenohumeral geometries between shoulders with anterior shoulder instability (ASI), unaffected contralateral shoulders, and healthy control shoulders. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Shoulder computed tomography (CT) scans of 36 patients with ASI and 36 matched healthy controls were retrieved and 3-dimensionally reconstructed. We measured the glenoid radius of curvature (GROC) in the anterior-posterior (AP) and superior-inferior directions, humeral head radius of curvature (HROC) in the AP direction, conformity index, glenoid height, glenoid width, glenoid index, stability angle, glenoid version, and glenoid depth. The differences between the groups were statistically calculated. CT scans of the unaffected contralateral shoulders from 21 of the ASI patients were also collected to identify the consistency of the bony structures in bilateral shoulders. Results: Patients with ASI had greater GROC in the AP direction (P < .001), HROC in the AP direction (P = .002), glenoid height (P = .005), and glenoid index (P < .001) and smaller conformity index (P < .001), glenoid width (P = .002), stability angle (P < .001), and glenoid depth (P < .001). In addition, the glenoid of the ASI patients was more anteverted compared with that of controls (P = .001). There was no statistical difference in half the measurements between the bilateral shoulder joints in patients with ASI. Conclusion: In this study, glenohumeral geometric differences were found between ASI patients and healthy control participants. Glenoid curvature and conformity index, based on bilateral comparisons of affected and contralateral shoulders, appear inherent and may predict ASI risk.

Kinematic analysis of damaged capsulolabral structure in patients with anterior shoulder instability using cine-magnetic resonance imaging.

Background: We assessed damaged anterior capsulolabral motion during axial shoulder rotation in patients with anterior shoulder instability. Methods: Twenty-nine shoulders of 28 patients with anterior shoulder instability who underwent cine-magnetic resonance imaging during axial rotation of the adducted arm were included. The motion was captured after an intra-articular injection of saline solution (10-20 mL). During imaging, the shoulder was rotated passively from maximum internal rotation to maximum external rotation in the first 10 s and then back to maximum internal rotation in the subsequent 10 s. We assessed the rotational angles of the damaged labrum during compressing and pulling the humeral head against the glenoid. Evaluation of the rotational angles was performed on a series of axial images through the humeral head center. Results: The mean angles that damaged labrum compressed and pulled off against the glenoid were 12.0 ± 19.1° and 2.8 ± 21.2°, respectively. Additionally, seven of the 29 shoulders showed that the damaged labrum compressed on the glenoid rim before the rotational angle exceeded 0° during external rotation. In 13 shoulders, the damaged labrum could remain repositioned on the glenoid rim over the neutral position during internal rotation. In two shoulders, the damaged labrum was not compressed against the glenoid at the maximum external rotation. The injected saline moved from the posterior to the anterior side of the glenohumeral joint during internal rotation in each shoulder. Conclusion: The damaged labrum could be positioned on the glenoid when the arm was in a traditional internal immobilization.

[A study of the correlation between glenohumeral joint congruence and stability in recurrent shoulder dislocations].

Objective: To investigate the correlation between glenohumeral joint congruence and stability in recurrent shoulder dislocations. Methods: Eighty-nine patients (89 sides) with recurrent shoulder dislocation admitted between June 2022 and June 2023 and met the selection criteria were included as study subjects. There were 36 males and 53 females with an average age of 44 years (range, 20-79 years). There were 40 cases of left shoulder and 49 cases of right shoulder. The shoulder joints dislocated 2-6 times, with an average of 3 times. The three-dimensional models of the humeral head and scapular glenoid were reconstructed using Mimics 20.0 software based on CT scanning images. The glenoid track (GT), inclusion index, chimerism index, fit index, and Hill-Sachs interval (HSI) were measured, and the degree of on/off track was judged (K value, the difference between HSI and GT). Multiple linear regression was used to analyze the correlation between the degree of on/off track (K value) and inclusion index, chimerism index, and fit index. Results: Multiple linear regression analysis showed that the K value had no correlation with the inclusion index ( P>0.05), and was positively correlated with the chimerism index and the fit index ( P<0.05). Regression equation was K=-24.898+35.982×inclusion index+8.280×fit index, R 2=0.084. Conclusion: Humeral head and scapular glenoid bony area and curvature are associated with shoulder joint stability in recurrent shoulder dislocations. Increased humeral head bony area, decreased scapular glenoid bony area, increased humeral head curvature, and decreased scapular glenoid curvature are risk factors for glenohumeral joint stability.

Suspension fixation of iliac bone grafts under arthroscopy is an effective method for the treatment of unstable bony Bankart disease of the shoulder joint in patients with joint relaxation.

PURPOSE: To evaluate the results of arthroscopic autologous iliac bone graft suspension fixation combined with the Remplissage procedure in the treatment of recurrent shoulder dislocation with bony Bankart lesions and joint hyperlaxity. METHODS: From 2018 to 2020, 22 patients with joint laxity underwent arthroscopic autologous iliac bone graft suspension fixation and Bankart repair combined with the Remplissage procedure due to recurrent shoulder dislocation. Clinical assessment included range of motion (forward flexion, abduction, 90° external rotation, conventional external rotation, adduction, and internal rotation), visual analog scale (VAS) score, Rowe score, University of California Los Angeles (UCLA) score, and Western Ontario Shoulder Instability Index (WOSI) score. Post-operatively, the healing of the bone graft was evaluated with computed tomography (CT) scanning. RESULTS: All 22 patients were followed up for a mean of 19.3 ± 4.1 months. CT imaging showed that the healing time of the bone graft was 6-8 weeks. The patient satisfaction rate was 100%, there were no cases of redislocation, all patients returned to their preinjury training state, and the fear test was negative. At the final follow-up, the UCLA, VAS, Rowe, and WOSI scores were 29.8 ± 2.1, 2.2 ± 0.8, 89.4 ± 4.2, and 482.3 ± 46.2, respectively (p < 0.001). CONCLUSION: Arthroscopic autologous iliac bone graft suspension fixation and Bankart repair combined with the Remplissage procedure are effective in preventing recurrent instability with joint hyperlaxity. Furthermore, no patient had redislocation. LEVEL OF EVIDENCE: IV.

Surgical delay for traumatic recurrent shoulder dislocations leads to inferior functional outcomes.

Background: The effect of time interval between injury and surgery on outcomes of Bankart repair surgery has not been published previously. The purpose of this study was to assess the effect of surgical delay on functional outcomes after arthroscopic Bankart repair. Method: One hundred and five athletes who underwent arthroscopic Bankart repair ± remplissage were enrolled in the study. Patients were divided into 2 groups depending upon the injury to surgery time- < 12 months (n = 19), and ≥12 months (n = 86). Depending upon the number of episodes of dislocation, patients were further categorized into 2 groups- <10 episodes (n = 66) and ≥10 episodes (n = 39). All patients were assessed post-operatively for functional outcomes (Modified Rowe's score, Constant Murley score) and return to sports at a minimum of 2 years of follow-up. Results: The mean injury to surgery time was 31.7 ± 23.1 months. The average number of episodes of dislocation before surgery were 10 (range 3-50). 49/105 (46.7%) patients returned to sports after a mean post-operative duration of 10.9 months. Athletes operated after a surgical delay of ≥12 months had inferior functional outcomes (Modified Rowe's score-89.5 ± 8.9 vs.77.4 ± 21.4; p = 0.02), lower rate of return to sports (14/19 vs. 35/86; p = 0.02) and higher mean time to return to sports (8.7 ± 1.9 vs. 11.5 ± 2.6; p < 0.05). Similarly, athletes who had ≥10 dislocations before surgery had inferior functional outcomes (Modified Rowe's score-84.5 ± 15.2 vs.72.9 ± 25.6; p = 0.004), lower rate of return to sports (37/66 vs. 12/39; p = 0.02) and higher mean time to return to sports (10.3 ± 2.4 vs. 12.6 ± 2.5; p < 0.05). Conclusion: A delay in surgery (≥12 months) or dislocation episodes of ≥10 are associated with inferior functional outcomes, lower rate of return to sports and higher surgical failure rate. Level of evidence: Level III; Prospective cohort study.

Effect of Rehabilitation on Recurrent Shoulder Dislocation Post-Latarjet Procedure: A Case Report.

Recurrent shoulder dislocation is often induced as a result of a traumatic situation that results in structural disease; however, a small subset of individuals suffer symptomatic recurrent shoulder instability without trauma. The glenohumeral articulation geometry offers a lot of flexibility at the sacrifice of inherent stability. The commonly dislocated joint is the shoulder joint as it has intrinsic instability that can lead to repeated dislocations. The procedure is designed to minimize the probability of problems. Physiotherapy is essential for regaining patients' mobility and enhancing their quality of life. A 36-year-old patient visited Acharya Vinoba Bhave Rural Hospital with complaints of pain graded 7/10 on the numerical pain rating scale and injury to the right shoulder joint after which there was repeated shoulder dislocation after a fall because of epilepsy five years back. The patient was diagnosed with recurrent shoulder dislocation which occurred approximately 50 times in a year as of January 24, 2022. The patient was managed with a Latarjet procedure on January 28, 2022. A well-planned physical therapy intervention significantly improved their overall status of health along with their ability to perform daily activities efficiently in post-operative patients with recurrent shoulder dislocation.

Increased nerve growth factor expression in the synovial tissues of patients with rotator cuff tears.

BACKGROUND: Rotator cuff tears (RCTs) are often associated with severe shoulder pain. Non-steroidal anti-inflammatory drugs, not recommended for long-term use, do not effectively manage RCT-induced pain, resulting in reduced quality of life. To improve management, a better understanding of the fundamental properties of RCT pain is needed. Here, we aimed to compare the expression levels of nerve growth factor (NGF) and cyclooxygenase-2 (COX-2) mRNA in the synovial tissues of patients with RCT-induced pain and patients with non-painful recurrent shoulder dislocation (RSD). METHODS: The study included 32 patients with RCT who underwent arthroscopic rotator cuff repair and 28 patients with non-painful RSD who underwent arthroscopic Bankart repair. Synovial tissue samples were harvested from subacromial bursa and rotator interval of RCT patients and from the rotator interval of RSD patients. Samples were analyzed quantitatively expression levels for NGF and COX2 mRNA and NGF protein. RESULTS: NGF mRNA and protein levels were significantly higher in the rotator interval of RCT patients than in the rotator interval of RSD patients (p = 0.0017, p = 0.012, respectively), while COX2 mRNA levels did not differ significantly between the two patient groups. In RCT patients, COX2 mRNA was more highly expressed in the rotator interval than in the subacromial bursa (p = 0.038), whereas the mRNA and protein levels of NGF did not differ between the two tissues. The expression of NGF mRNA in the synovium of the rotator interval was significantly correlated with the numeric rating scale of pain (ρ = 0.38, p = 0.004). CONCLUSION: NGF mRNA and protein levels were elevated in patients with painful RCT compared with those in patients with non-painful RSD, whereas COX-2 levels were comparable in the two patient groups. These findings provide insights into novel potential strategies for clinical management of RCT.

Arthroscopic Bankart repair following traumatic recurrent shoulder dislocation: A prospective review of 30 cases.

BACKGROUND: Literature on outcomes of arthroscopic Bankart repair at the intervening time intervals in traumatic recurrent dislocation of shoulder joint is limited. STUDY DESIGN: Case series. SUBJECTS AND METHODS: A prospective review of 30 shoulders, aged 20-40 years with clinically and magnetic resonance imaging established findings that were treated with primary arthroscopic Bankart repair and followed up for a minimum of 2 years. Outcomes were evaluated using Rowe score and University of California at Los Angeles (UCLA) scoring system. RESULTS: The mean age was 26.40 years. All patients had definite trauma history. Average number of dislocation was 13.77 + 18.435 (range: 3-100). Time duration from first dislocation to surgery was an average of 4.80 + 3.576 years. The average size of the lesion was approximately 31% of the glenoid circumference. The number of suture anchors used for fixation did not correlate significantly with any of the scores. The mean Rowe and UCLA scores were 94.16 ± 9.7 and 33.83 ± 3.32, respectively, at final follow-up. The average duration of hospital stay was 7 days. Of the 30 patients, 2 (6.66%) had dislocation events post-operatively. Returns to pre-injury level were available for 27 (90%) of 30 patients. Multivariate analysis of independent Variables: age; side and number of dislocations, time to surgery, duration of surgery, size of lesion, number of anchors, and concurrent Hill-Sachs lesion, shown to have no significant relationship to outcomes. CONCLUSION: Arthroscopic Bankart repair is an effective and safe technique for treating anterior glenohumeral instability in patients with recurrent traumatic shoulder dislocation.

Arthroscopic Bankart repair for the acute anterior shoulder dislocation: systematic review and meta-analysis.

BACKGROUND: The ideal treatment of acute anterior shoulder dislocation remains one of the topics that spark debate over the value of primary repair for the first-time anterior shoulder dislocation. The high rate of complications especially in young adults, such as recurrent instability, residual pain, and inability to return to sports, has led to the quest for an ideal management of such injuries. OBJECTIVE: In this meta-analysis, we compare between the immediate arthroscopic repair and conservative treatment of primary anterior shoulder dislocation as well as arthroscopic reconstruction of recurrent anterior shoulder dislocation. Outcome measures were failure rate (dislocation, subluxation, and instability) and revision rates. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched several database including PubMed, MEDLINE, EMBASE, Web of Science, Cochrane Library, and ClinicalTrials.gov through August 2017 to identify observational and experimental randomized controlled trials comparing the outcomes of immediate arthroscopic repair and conservative treatment of primary shoulder dislocations as well as arthroscopic reconstruction of recurrent dislocation. The primary outcome was failure rate, whereas, secondary outcomes were revision rate and functional outcomes. RESULTS: Out of the 710 studies identified, 12 were eligible for meta-analysis. The estimated pooled failure rate was 13.7% (7.7%-19.6%), whereas, the pooled revision rate was 7.1% (3.8%-10.4%) in immediate arthroscopic repair of primary shoulder dislocation. The odd ratio (OR) of failure and revision rates were significantly lower in arthroscopic repair of primary shoulder dislocation compared to conservative treatment (OR 0.103, 95% CI [0.052, 0.201]), (OR 0.217, 95% CI [0.078, 0.607]), respectively. The odd ratio (OD) of failure and revision rates were lower in arthroscopic repair of primary shoulder dislocation compared to arthroscopic reconstruction of the recurrent shoulder dislocation; however, the difference was statistically insignificant (OR 0.423, 95% CI [0.117, 1.522]) and (OR 0.358, 95% CI [0.044, 2.920]) respectively. CONCLUSION: The outcome of immediate arthroscopic repair of primary anterior shoulder dislocation is superior and encouraging with significant reduction in failure and revision rates compared to conservative treatment. Nevertheless, the failure and revision rates are statistically insignificant compared to arthroscopic reconstruction of recurrent dislocation. Hence, there is evidence to support immediate arthroscopic repair option for primary anterior shoulder dislocations over conservative treatment in young active patients, in order to reduce the risk of failure and revision rates. However, the evidence is inconclusive compared to arthroscopic reconstruction of recurrent dislocation.
