Recurrent Anterior Dislocation Research Articles

Latarjet operation carries three times the risk of failure in seizure versus non-seizure recurrent anterior dislocation of the shoulder joint: outcome of a systematic review with meta-analysis.

Recurrent anterior shoulder dislocation (RASD) in cases of seizure disorders (SDs) total 50%-80% of all SD-associated shoulder instabilities. Based on the extent of bone loss, treatment options include bony and soft-tissue reconstructions, arthroplasty, and arthrodesis. The primary objective of this paper was to review the treatment options for RASD in SDs. Several bibliographic databases were searched for RASD treatment options in SD patients. The demographic outcome measures, the failure rate (defined as the relative risk of recurrence of dislocation postoperation), and the postoperative seizure recurrence rate were recorded. We pooled 171 cases (187 shoulders) from 11 studies. Of these, one, five, two, two, and one reports studied Bankart's operation with remplissage (27 cases/29 shoulders), the Latarjet procedure (106/118), bone block operation (21/23), arthroplasty (11/11), and arthrodesis (6/6), respectively, in treating SD-associated RASD. The relative risk of failure between SD and non-SD patients was 3.76 (1.36-10.38) after the Latarjet operation. The failure rates were 17% and 13% for Bankart's operation with remplissage and the Latarjet procedure in SD patients, respectively, but 0% each for bone block operation, arthroplasty, and arthrodesis. The total rate of seizure recurrence after operation was 33% of the pooled cases. SD recurrence in the postoperative period, the size of the bone block, and the muscular attachments to a small coracoid autograft are the determinants of failure among various reconstructive operations in SD-associated RASD.

The Functional Outcome Between Arthroscopic and Open Surgery for Recurrent Anterior Shoulder Instability: A Systematic Review

Background: It remains unknown if arthroscopic repair of recurrent anterior shoulder instability is as effective as open repair. The aim of this study was to compare the functional outcome between arthroscopic and open repair for recurrent Anterior Shoulder Instability. Methods: We searched the Cochrane Library, EMBASE, and PubMed extensively for studies comparing open versus arthroscopic repair for recurrent anterior shoulder dislocations until March 1, 2021. The PRISMA guidelines were utilised by two different researchers to assist them in selecting pertinent papers. Because there were few studies, there was no restriction on publication status, open and arthroscopic repair technique, or patient demographics. Results: For recurrent anterior shoulder dislocations, five randomised controlled trials assessed the use of open repair against arthroscopic surgery. According to these investigations, there is no discernible difference between the two operational strategies. At present, there are no known long-term follow-up data that describe the outcomes of either surgical method. Every inquiry had flaws in the way it was designed, which reduced the reliability of the results. Conclusion: There is insufficient data from randomised controlled trials to conclude that there is a statistically significant difference between the groups that underwent open repair and those that underwent arthroscopic surgery in terms of redislocation rates, return to activity, and functional outcomes. After arthroscopic surgery, range of motion is slightly better than after open repair. No recommendations regarding the best course of surgery can be given.

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 tocompare 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 modifiedPutti-Platt surgery. Functional outcomes were assessed at sixmonths 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 Bankart versus Open Latarjet; Short-to-Mid-Term Outcomes of Recurrence and Patient-Reported Outcomes in Patients with Recurrent Anterior Shoulder Dislocation

Objectives This retrospective comparative study compared the short to mid-term outcomes of arthroscopic Bankart repair and open Latarjet procedures in patients with recurrent anterior shoulder instability. Methods Patients who underwent either arthroscopic Bankart repair or open Latarjet procedures between 2008 and 2020, with at least one year of follow-up, were included. Arthroscopic Bankart repairs were performed on shoulders with minimal glenoid bone loss (<15%), and the Latarjet procedure was performed if the preoperative computed tomography (CT) scan showed a 15% bone loss on the glenoid side or 30-40% humeral head bone loss. Their surgery results and patient-reported outcome measures (PROMs) were assessed using the Oxford Shoulder Score (OSS) and Shoulder Pain and Disability Index (SPADI). Results 133 patients were analyzed in Latarjet (n = 67) and Bankart groups (n = 66). Before surgery, the two groups of patients were similar regarding surgery side, hand dominance, education level, occupation difficulty level, and smoking (P>0.05). However, Latarjet’s patients were younger (32 vs. 35, P=0.04), had a higher proportion of males (96% vs. 82%, P=0.01), and had a significantly shorter follow-up period (3.2 vs. 6.4 years, P<0.001) than the Bankart group. There was no significant difference between the Latarjet and Bankart groups regarding the follow-up’s OSS score (37 vs. 36; P=0.94) and SPADI score (22 vs. 24, P=0.80). Dislocation was observed in only one patient (1.5%) in the Latarjet group (P=1.0). Subluxation was observed in 5 patients (7.5%) of the Latarjet group and three patients (4.5%) of the Bankart group (P=0.4). The overall instability rate was similar (P>0.05). Conclusion Our findings suggest that both arthroscopic Bankart repair and open Latarjet are reliable techniques in short to mid-term follow-up based on the glenoid bone loss cut-off of 15%.

Outcome of Modified Open Latarjet Operation in the Treatment of the Recurrent Anterior Shoulder Dislocation: A Cohort Study

Introduction: Shoulder instability is defined as a symptomatic translation of the humeral head about the glenoid fossa during active shoulder motion. Anteroinferior glenoid bone loss or labrum avulsion is most often a consistent finding in recurrent dislocation. The modified open Latarjet procedure is one of the most effective methods of treatment for patients with recurrent shoulder instability with glenoid bone loss. Aim: To determine the functional outcome of the congruent arc modification of the open Latarjet procedure. Materials and Methods: This prospective cohort study was conducted at a tertiary healthcare centre in Bhopal, Madhya Pradesh, India between January 2018 and December 2020. A total of 25 patients with recurrent anterior shoulder dislocation underwent treatment using the modified open Latarjet procedure. Two patients were lost to follow-up, resulting in the evaluation of 23 patients. All patients underwent a 3D Computed Tomography (CT) scan to document glenoid bone loss. The intensity of pain, activity level, strength of abduction, and Range of Motion (ROM) were assessed to calculate the Constant Shoulder Score for pre- and postoperative evaluation of functional outcomes. Follow-ups were conducted at 3 months, 6 months, 1 year, and 2 years after surgery. The data was analysed using the Wilcoxon’s signed-rank test, and Spearman’s correlation coefficient was used to identify associations between various variables. Results: A total of 23 male patients aged between 18 and 63 years were included. The average age of patients was 30.35±11.27 years. Preoperatively, only 3 patients (13.04%) had good to excellent Constant Shoulder Scores. However, no statistically significant variation in Constant Score was observed three months after surgery. Six months post-surgery, 17 patients (73.92%) showed good to excellent scores. Nearly one year after surgery, 21 patients (91.3%) had good to excellent outcomes. At the final follow-up, 22 patients (95.65%) demonstrated good to excellent outcomes. A statistically significant improvement in good to excellent scores was noted six months postoperatively (p-value <0.001). A total of 20 patients (86.96%) achieved full ROM, with only 3 patients (13.04%) reporting mild to moderate limitations in shoulder ROM. None of the patients experienced redislocation, and the apprehension test was positive in only one patient. Conclusion: The modified open Latarjet procedure is a reliable method for providing stability and Self confidence to patients with recurrent shoulder instability and glenoid bone loss.

GLENOHUMERAL DISLOCATION, ANATOMICAL DESCRIPTION, EPIDEMIOLOGY, MECHANISMS OF ACTION, CLASSIFICATION, CLINICAL PRESENTATION, IMAGING PRESENTATION, TREATMENT AND COMPLICATIONS

Introduction: Acute shoulder injuries that are common here include acromioclavicular joint injuries, clavicle fractures, glenohumeral dislocations, proximal humerus fractures and rotator cuff tears. Glenohumeral dislocations are frequently attributed to contact sports, as well as bicycle accidents, falls and high-impact trauma. Patients present several specific characteristics that will depend on the type of dislocation. Objective: to detail the current information related to glenohumeral dislocation, in addition to its description, epidemiology, classification, clinical evaluation, imaging presentation, treatment and complications of the different types of glenohumeral dislocation. Methodology: a total of 32 articles were analyzed in this review, including review and original articles, as well as clinical cases, of which 20 bibliographies were used because the other articles were not relevant for this study. The sources of information were PubMed, Google Scholar and Cochrane; the terms used to search for information in Spanish, Portuguese and English were: glenohumeral dislocation, shoulder pain, upper limb dislocation, shoulder reduction, shoulder dislocation. Results: Shoulder dislocations are usually anterior. In recurrent anterior dislocation, most recurrences occur in the first 2 years and mostly in males. Age at the time of initial dislocation has the greatest influence; incidence is not related to the duration or type of immobilization. The approximate recurrence rate in all age zones is 50%, however it increases to 89% in 14 to 20 year olds. Conclusions: The shoulder joint is frequently associated with dislocations, accounting for a large percentage of all dislocations, with anterior shoulder dislocations being more common. Anatomical, clinical and imaging knowledge play an important role in the diagnosis, allowing a better classification of the type of dislocation, which has a better impact on the treatment. The immobilization and physiotherapeutic approach will vary depending on the pathology, the age of the patient, the existence of recurrence and other complications. KEY WORDS: glenohumeral dislocation, shoulder reduction, shoulder dislocation.

Moment arms of the coracobrachialis and short head of biceps following a Latarjet procedure: a modeling study

BackgroundThe Latarjet procedure transfers the coracoid process to the anterior glenoid. This prevents recurrent anterior humeral dislocation but alters the origin of the coracobrachialis (CBR) and short head of bicep (SHB). The impact of this alteration on the moment arms of these muscles has not been examined. MethodsThe Newcastle Shoulder Model was updated with 15 heathy cadaveric bone models to create customized shoulder models. The CBR and SHB muscles were attached to the anterior glenoid via an elliptical wrapping object. Muscle moment arms were calculated for abduction, forward flexion, scapula plane elevation and internal rotation with 20⁰ and 90⁰ abduction. Statistical comparison between native and Latarjet moment arms was performed using spm1D. ResultsBy transferring the origin of CBR and SHB to the anterior glenoid, both muscles had extension moment arms during glenohumeral elevation in coronal, sagittal, and scapular plane. Their average moment arms during abduction (CBR: -30.4±3.2mm; SHB: -29.8±3.0mm) and forward flexion (CBR: -26.0±3.1mm; SHB: -26.2±3.2mm) suggested that their role after Latarjet changed, compared with that of their role in a native shoulder (p<0.001). At higher abduction levels both the muscles had higher internal rotation moment arms compared to the native shoulder. ConclusionThe Latarjet procedure affected the moment arms of the CBR and SHB. Both muscles had increased extension and internal rotation moment arms at higher degrees of elevation, compared to the native shoulders, this suggests that these muscles act as dynamic stabilizers after Latarjet.

Clinical and Functional Outcomes of Arthroscopic Bankart Repair among Patients with Recurrent Anterior Shoulder Dislocation

OBJECTIVE: To note the functional outcome of recurrent anterior shoulder dislocation with Bankart repair (BR) treated with arthroscopic stabilisation with suture anchors. METHODOLOGY: This prospective cohort study was conducted at the Department of Orthopedic Surgery, Lahore General Hospital, Lahore, from January 2021 to June 2022. Patients undergoing arthroscopic BR with anterior instability of the glenohumeral joint with at least &gt;6 episodes of dislocation/subluxation in the last six months were analysed. Functional outcomes were assessed at one-month, three-month and six month intervals post-surgery using "Modified University of California Los Angeles (UCLA)" and "Simple Shoulder Test (SST)". RESULTS: Of 25 patients, 24 (96.0%) were male. The mean age was 27.20±4.0 years. The mean duration of symptoms was 9.1±6.2 months. In 16 (64.0%) patients, 2-suture anchors were utilised, while 3-suture anchors were used in the remaining 9 (36.0%) patients. Pre-surgery, the mean UCLA score was 16.4±5.6 and improved to 1-month, 3-month and 6-month as 16.6±5.1, 22.8±6.2 and 28.4±6.6 respectively (p&lt;0.001). Pre-surgery, the mean SST score was 4.7±2.4 which improved to 1-month, 3-month and 6-month as 5.4±2.6, 8.1±3.3 and 11.2±3.1 respectively (p&lt;0.001). All patients (100%) had full range of motion after six months post-surgery. CONCLUSION: Arthroscopic BR in recurrent anterior shoulder dislocation was a reliable procedure regarding functional outcomes and range of motion after six months of follow-up. KEYWORDS: Arthroscopy, Bankart repair, shoulder dislocation, suture anchors, range of motion

Remodeling process and clinical outcomes following all-arthroscopic modified Eden-Hybinette procedure using iliac crest autograft and 1-tunnel double Endobutton fixation system.

Arthroscopically modified Eden-Hybinette procedures for glenohumeral stabilization have been used for a long time. With the advancement of arthroscopic techniques and the development of sophisticated instruments, a double Endobutton fixation system has been used clinically to secure bone graft to the glenoid rim placed through a specifically designed guide. The purpose of this report was to evaluate clinical outcomes and serial glenoid remodeling process following all-arthroscopic anatomical glenoid reconstruction using autologous iliac crest bone grafting technique through 1-tunnel fixation. Forty-six patients with recurrent anterior dislocations and significant glenoid defects greater than 20% underwent arthroscopic surgery with a modified Eden-Hybinette technique. Instead of firm fixation, autologous iliac bone graft was fixed to the glenoid by double Endobutton fixation system through 1-tunnel placed in the glenoid surface. Follow-up examinations were performed at 3, 6, 12, and 24months. The patients were followed up for a minimum of two years using the Rowe score, the Constant score, the Subjective Shoulder Value, and the Walch-Duplay score; patient satisfaction with the procedure outcome was also rated. Graft positions, healing, and absorption were evaluated postoperatively with computed tomography imaging. At a mean follow-up of 28months, all patients were satisfied and had a stable shoulder. The Constant score improved from 82.9 to 88.9 points (P ＜ .001), the Rowe score, improved from 25.3 to 89.1 points (P<.001), the Subjective Shoulder Value improved from 31% to 87% (P<.001), and the Walch-Duplay score improved from 52.5 to 85.7 points (P ＜ .001). One donor-site fracture occurred during the follow-up period. All grafts were well-positioned and achieved optimal bone healing with zero excessive absorption. The preoperative glenoid surface (72.6%±4.5%) increased significantly immediately after surgery to 116.5%±9.6% (P ＜ .001). After a physiological remodeling process, the glenoid surface remained significantly increased at the last follow-up (99.2%±7.1%) (P ＜ .001). The glenoid surface area appeared to decrease serially when compared between the first 6months and 12months postoperatively, while there was no significant interval change between 12 and 24months postoperatively. Patient outcomes were satisfactory following the all-arthroscopic modified Eden-Hybinette procedure using an autologous iliac crest grafting technique through one-tunnel fixation system with double Endobutton. Graft absorption mostly occurred on the edge and outside the ''best-fit'' circle of the glenoid. Glenoid remodeling occurred within the first year after all-arthroscopic glenoid reconstruction with an auto iliac bone graft.

Correlation between glenoid bone structure and recurrent anterior dislocation of the shoulder joint.

The aim of the study was to investigate the anatomical characteristics and symmetry of the bilateral glenoid structures of Chinese people and to explore the relationship between the glenoid bone structure and recurrent anterior dislocation. The control group included 131 individuals with no history of shoulder dislocation. The dislocation group consisted of 131 patients with a history of unilateral shoulder dislocation. All subjects underwent computed tomography scans. Glenoid shape (pear-shaped, inverted comma-shaped, oval-shaped), width, height, depth, version angle, area, maximum fitting circle area and volume were measured. There was no significant difference in normal bilateral glenoid of Chinese people (p > 0.05). There were statistically significant differences in depth, height to width ratio, maximum fitting circle area and shape between the dislocation and control groups (p < 0.05). Regression analyses showed that the glenoid depth (odds ratio [OR] 0.48; p < 0.01), the glenoid height to width ratio (OR 28.61; p < 0.01), the glenoid maximum fitting circle area (OR 1.01; p < 0.01) and the glenoid shape (p <0.05; pear-shaped OR 0.432; inverted comma-shaped OR 0.954) were associated with anterior shoulder instability. Pear-shaped and inverted comma-shaped glenoid had lower risk of recurrent anterior shoulder dislocation compared to oval glenoid. Receiver operating characteristic curve analysis showed that individuals with anterior shoulder instability had smaller glenoid depth and larger height to width ratio and the glenoid maximum fitting circle area compared with the control group. The normal bilateral glenoids of Chinese people are basically symmetrical. The glenoid shape, depth, height to width ratio and maximum fitting circle area are risk factors for recurrent anterior shoulder dislocation. Evaluation of the glenoid bone structure enables more accurate prediction of the risk of recurrent shoulder dislocation.

Results of arthroscopic treatment for anteroinferior shoulder instability using a single anterior working portal using birdbeak

BackgroundThe shoulder joint is the joint with the most dislocations in all joints. The arthroscopic surgery method is considered the gold standard because it creates less soft tissue damage, shorter hospitalization and surgery time, and less restriction of movement after surgery in shoulder instability. Anterior single portal technique has become popular recently. In this study, it was aimed to evaluate the results of the anterior single portal repair technique using “birdbeak”. We try to evaluate if this technique is a reliable technique and has the same or more advantages of two portal arthroscopic surgery and make the surgery easier for surgeons.MethodsIn the total of 40 patients who underwent arthroscopic surgery for traumatic recurrent anterior shoulder dislocation between January 2017 and February 2020, this study included 19 patients with the surgical technique of arthroscopic isolated anterior labrum tear repair using a birdbeak from the anterior single working portal. Clinical results were evaluated with the Simple Shoulder Test (SST), Rowe Score for Instability (RWS) and Oxford Shoulder Instability Score (OSIS) tests before and after surgery. The relationship between the time to surgery after the first dislocation and clinical outcomes was also examined in the study. Kolmogorov-Smirnov and Shapiro-Wilk tests were used to control the assumption of normality. In addition, Pearson correlation and Spearman correlation analyzes were used to test the relationship between the variables.ResultsThe mean follow-up period of the 19 patients included in this study was 33.1 months. The mean time to surgery after the first dislocation was 18.4 months. The mean preoperative number of dislocations was 5.3. The mean number of anchors used in the repair was 2.1. No recurrent dislocations were observed after surgery. A significant difference was observed between preoperative and postoperative SST, RWS and OSIS scores (respectively, p = 0.000 < 0.001, p = 0.000 < 0.001, p = 0.000 < 0.001). There was no statistically significant relationship between the time elapsed after the first dislocation and the postoperative SST, RWS, OSIS scores (respectively, p = 0.43 > 0.05, p = 0.39 > 0.05, p = 0.31 > 0.05).ConclusionIt has been observed that the repair technique applied using the “birdbeak” from the anterior single working portal is a successful treatment, and further studies are required due to the limited literature.

Evaluation of Clinical &amp; Functional Outcomes Bristow Latarjet Procedure in the Management of Recurrent Anterior Shoulder Dislocation

Background: Glenohumeral joint is highly susceptible to dislocation due to its wide range of movements. Recurrent anterior shoulder dislocations are common in young adults. The Bristow Latarjet procedure is one of the effective techniques for the treatment of recurrent anterior shoulder dislocation. This study aimed to assess the clinical and functional outcome of the Bristow Latarjet procedure in the management of recurrent anterior shoulder dislocation. Material &amp; Methods: This prospective interventional study was conducted in the Department of Orthopaedic Surgery, BSMMU, from October 2017 to September 2019. Within this period, a total of 40 cases of recurrent anterior shoulder dislocation that meet inclusion criteria were taken as a sample. Patients were evaluated both pre and postoperatively for functional outcomes according to Rowe’s score for instability. A purposive non-randomized sampling technique was used in this study. All the data were compiled and sorted properly and the quantitative data were analyzed statistically by using Statistical Package for Social Science (SPSS-25). The results were expressed as frequency, percentage and mean ± SD. Paired Student’s‘t’ test was performed to compare pre and final postoperative follow-up. The level of significance was calculated at a confidence interval of 95% and p-value &lt;0.05. Results: : In this study age of the patient ranged from 18-40 years and the mean age was 28.2±6.3. 29(72.5). Surgery was done within 4-6 months of the first dislocation in 5 patients, within 6-12 months in 21 patients and after 12 months in 14 patients. The mean (±SD) Rowe score for instability was significantly (p&lt;0.001) higher 6 months after the Bristow Latarjet procedure at 91.87(±9.00) in comparison to preoperative periods 52.62(±18.40). Results were excellent in 32(80%), good in 4(10%), fair in 3(7.5%) and poor in 1(2.5%) patients. 36(90%) patients were in the satisfactory group and only 4(10%) in the unsatisfactory group. Only 1(2.5%) patient developed screw migration, 2(5%) patients developed subluxation, and 1(2.5%) patient developed postoperative arthritis. Conclusion: It can be concluded that the Bristow-Latarjet procedure is a very effective and safe procedure with reduced complications, presenting very satisfactory functional results in the treatment of recurrent anterior shoulder dislocation.

Effectiveness of arthroscopic autologous iliac bone grafting with double-row elastic fixation for recurrent anterior shoulder dislocation with massive glenoid bone defect

To investigate the effectiveness of arthroscopic autologous iliac bone grafting with double-row elastic fixation in treatment of recurrent anterior shoulder dislocation combined with massive glenoid bone defects. Between January 2018 and December 2021, 16 male patients with recurrent anterior shoulder dislocation combined with massive glenoid bone defects were treated with arthroscopic autogenous iliac bone grafting and double-row elastic fixation. The patients were 14-29 years old at the time of the first dislocation, with an average age of 18.4 years. The causes of the first dislocation included falling injury in 5 cases and sports injury in 11 cases. The shoulders dislocated 4-15 times, with an average of 8.3 times. The patients were 17-37 years old at the time of admission, with an average age of 25.1 years. There were 5 left shoulders and 11 right shoulders. The preoperative instability severity index (ISIS) score of the shoulder joint was 5.8±2.1, and the Beighton score was 4.3±2.6. The University of California Los Angeles (UCLA) score, Constant score, American Shoulder and Elbow Surgeons (ASES) score, and Rowe score were used to evaluate shoulder function, and the degree of the glenoid bone defect repair was observed based on CT after operation. All incisions healed by first intention, and no complication such as incision infection or neurovascular injury occurred. The patients were followed up 12 months. At 12 months after operation, UCLA score, Constant score, ASES score, and Rowe score all significantly improved when compared with the scores before operation ( P<0.05). CT imaging showed the degree of glenoid bone defect was significantly smaller at immediate, 6 and 12 months after operation when compared with that before operation ( P<0.05), and the bone blocks healed with the scapula, and bone fusion had occurred at 12 months. Arthroscopic autologous iliac bone grafting with double-row elastic fixation is a safe treatment for recurrent anterior shoulder dislocation combined with massive glenoid bone defects, with good short-term effectiveness.

Research progress of the diagnosis and treatment of anterior shoulder instability

The shoulder joint is the most prone to dislocation in the whole body, and more than 95% of them are anterior dislocation. Improper treatment after the initial dislocation is easy to lead to recurrent anterior dislocation or anterior shoulder instability, and the outcomes following conservative treatment is poor. Anterior shoulder instability can damage the soft tissue structure and bone structure that maintain the stability of shoulder joint, among which bone structure is the most important factor affecting the stability of shoulder joint. Diagnosis should be combined with medical history, physical examination, and auxiliary examination. Currently, three-dimensional CT is the most commonly used auxiliary examination means. However, various bone defect measurement and preoperative evaluation methods based on three-dimensional CT and the glenoid track theory have their own advantages and disadvantages, and there is still a lack of gold standard. Currently, the mainstream treatment methods mainly include Bankart procedure, coracoid process transposition, glenoid reconstruction with free bone graft, Bankart combined with Remplissage procedure, and subscapular tendon binding tamponade, etc. Each of these procedures has its own advantages and disadvantages. For the diagnosis and treatment of anterior shoulder instability, there are still too many unknown, further research and exploration need to be studied.

Functional outcome of Latarjet for recurrent anterior shoulder dislocation

Background and Aim: Recurrent shoulder dislocations can be treated with a variety of surgical procedures. However, soft-tissue repair appears to be ineffective in all cases of recurrent shoulder dislocation. The present study aimed to determine the Latar jet technique functional outcome for recurrent anterior shoulder dislocation. Patients and Methods: This descriptive cross-sectional study was conducted on 42 recurrent shoulder dislocation patients at the MTI Lady Reading Hospital Peshawar from January 2019 to December 2022. All the eligible patients were operated with open Latar jet procedure. Constant-Murley shoulder score was used for the assessment of functional outcome at 6th months. SPSS version 27 was used for data analysis. Results: Of the total 42 patients, there were 40 (95.2%) male and 2 (4.8%) female. The overall mean age was 46.8±8.4 years. The right and left-side involvement was found in 32 (76.2%) and 12 (23.8%) respectively. The incidence of poor, fair, good, and very good outcomes was 3 (7.1%), 4 (9.5%), 12 (28.6%), and 23 (54.8%) respectively. There was significant improvement in shoulder motion and reduction in pain after 6th month's follow-up.

Arthroscopic Dynamic Anterior Stabilization Using Either Long Head of the Biceps or Conjoined Tendon Transfer for Anterior Shoulder Instability Results in a Similarly Low Recurrence Rate

To compare the clinical outcomes of arthroscopic dynamic anterior stabilization (DAS) between transferring the long head of the biceps (DAS-LHB) and the conjoined tendon (DAS-CT) for anterior shoulder instability with <15% glenoid bone loss. From January 2016 to May 2019, a total of 63 patients who underwent DAS for recurrent anterior shoulder dislocation with <15% glenoid bone loss were included, comprising 33 patients in DAS-LHB group and 30 patients in DAS-CT group. Clinical outcomes were assessed preoperatively and at a minimum 3-year follow-up, including patient-reported outcomes, range of motion, and return to sports (RTS). Postoperative recurrent instability (including dislocation, subluxation, and subjective instability with a positive apprehension test), revisions and complications also were recorded. No significant demographic characteristics difference was detected between the DAS-LHB (26.3 ± 7.9 years) and DAS-CT groups (26.0 ± 6.7 years). At the latest follow-up, there were no significant differences between the 2 groups in functional scores: Oxford Shoulder Instability Score (14.8 ± 2.8 vs 15.2 ± 3.6), Rowe score (95.9 ± 6.5 vs 93.2 ± 10.2), visual analog scale for pain (0.8 ± 1.2 vs 0.7 ± 1.7), and American Shoulder and Elbow Surgeons (95 ± 8.8 vs 95.2 ± 9.1) (all P > .218). No significant difference was detected between groups in the rates of RTS (90.1% vs 86.7%, P= .700) and RTS at previous level (78.7% vs 73.3%, P= .258), respectively. No recurrent dislocation occurred in either group. One patient felt occasional subluxation in the DAS-LHB group, and one was positive for the apprehension test in each group. One patient presented with postoperative shoulder stiffness and underwent a secondary arthroscopic debridement in the DAS-CT group. Comparable rates of recurrence, complication, return to sports, and subjective shoulder function were observed between DAS-LHB and DAS-CT groups. Level III, retrospective comparative therapeutic trial.

Short-term Complications of Open Latarjet Procedure for Recurrent Anterior Shoulder Dislocation.

Anterior dislocation is the most common type of shoulder dislocation, and even after appropriate treatment, recurrence after a primary traumatic anterior dislocation is highly frequent. Surgical options for treating recurrent anterior dislocations mainly include Bankart arthroscopic and Latarjet open surgery. We aimed to evaluate the outcomes and complication rates of the open Latarjet procedure in a series of patients with recurrent anterior shoulder dislocation. A total of 55 patients with recurrent anterior shoulder dislocation who underwent an open Latarjet procedure were included in this retrospective cohort study. Shoulder range of motion and postoperative complications, including neurapraxia, re-dislocation, hematoma, infection, dehiscence, implant failure, and pain, were evaluated. The mean age of the patients was 27.7 ± 6.5 years . The mean time interval after the first dislocation was 3.4 ± 2.7 years . The mean preoperative and postoperative forward flexion (P = 0.200), abduction (P = 0.200), external rotation (P = 0.066), and internal rotation (P = 0.310) were not significantly different. Postoperative complications included 1 case of postoperative musculocutaneous nerve neurapraxia, 1 case of re- dislocation, 1 case of wound dehiscence, and 2 cases of screw breakage. Postoperative pain was also recorded in 11 (20%) patients that were either in the form of occasional night pain (n = 6) or activity-dependent pain (n = 5). Open Latarjet procedure is an efficient procedure for the treatment of recurrent anterior shoulder dislocation. However, its rate of complications remains relatively high, and surgeons must consider this drawback in their decision-making and address patients' expectations.

TREATMENT OF RECURRENT ANTERIOR SHOULDER DISLOCATION USING THE LATARJET TECHNIQUE.

To describe the functional results, recurrence rate, postoperative radiographic appearance, and complications of patients undergoing the Latarjet procedure over 24 months. Retrospective case series, including adult patients with recurrent traumatic anterior glenohumeral dislocation undergoing the Latarjet procedure. We clinically evaluated patients preoperatively by the Rowe score and at six, 12, and 24 months after the procedure. The positioning, consolidation, and resorption of the graft were analyzed by plain radiography. The recurrence rates and other complications were also described. We analyzed 40 patients (41 shoulders). The Rowe score median increased from 25 before surgery to 95 at 24 months after surgery (p < 0.001). We observed graft resorption in three cases (7.3%) and consolidation in 39 (95.1%). Most grafts presented adequate placement. We observed two recurrences (4.8%), one case of dislocation and one of subluxation. Seven patients (17.1%) had a positive apprehension test. The study had no cases of infection, neuropraxia, or graft breakage. Latarjet surgery is a safe and effective procedure in the treatment of recurrent anterior dislocation of the shoulder. This surgery enables a statistically significant improvement according to the Rowe score, with a low number of recurrences. Level of Evidence IV, Case Series.

Functional Outcome of Open Latarjet Procedure for Recurrent Anterior Shoulder Dislocation

OBJECTIVES To find the functional outcome of the open Latarjet method for recurrent anterior shoulder dislocation. METHODOLOGY The current retrospective study was conducted at the Orthopedic and Trauma Department of the Khyber Teaching Hospital in Peshawar from September 2020 to August 2021. A total of 31 patients were included in the study, of which 29 were males and 2 were females. A detailed medical history was obtained through physical examination, and all necessary laboratory tests were requested. AP and axillary views of plain X-ray radiographs were taken. We used a CT scan on all the patients to calculate the humeral and glenoid bone loss. We had all patients undergo an MRI to rule out soft tissue pathology. Six months after surgery, the outcome was graded using the Constant Murley Score on a good, good, fair, and poor scale. RESULTS In this study open Latarjet procedure was done in 31 patients with 29 males (93.4%) and two females (6.45%). The right-sided shoulder was involved in 24 (77.14 %) patients, while the left shoulder was involved in 7 patients (22.58%). A bipolar lesion in the shoulder with bone loss was seen on the glenoid side at 17.5% (range 10-25%), and the humeral side was 22.5%. Follow-up was done for six months in which 22 patients had a very good outcome (70.96%), six patients had a good outcome(19.35%), two patients had a fair outcome(6.45%), and one patient had a poor outcome(3.22%). There were no major complications seen like graft fractures, graft malposition, neurovascular compromise, and hardware breakage CONCLUSION Recurrent anterior shoulder instability can be effectively treated with open Latarjet with excellent functional outcomes and a very low complication rate and recurrence.
