BACKGROUND: The Latarjet procedure (LP) is performed as a primary stabilization procedure (primary LP) and a salvage procedure when an earlier shoulder stabilization procedure has failed (salvage LP). However, whether primary LP or salvage LP provides better outcomes for anterior shoulder instability remains unknown.
METHODS: Two independent reviewers performed the literature search based on the PRISMA guidelines. A comprehensive search of PubMed, Embase, web of science and Cochrane Library was performed from their inception date to December 4, 2023. Inclusion criteria mainly included the comparison of postoperative outcomes between primary and salvage LP, English language, and full text availability. Two reviewers independently examined the literature, collected data, and evaluated the methodological robustness of the included studies. The Methodological Index for Nonrandomized Studies was used to evaluate the quality of nonrandomized studies. Recurrent instability, complications, reoperations, return to sports, patient-reported outcomes, and range of motion were assessed. Statistical evaluations were conducted using Manager V.5.4.1 (The Cochrane Collaboration, Software Update, Oxford, UK).
RESULTS: Twelve studies were included in the systematic review, with 940 shoulders undergoing primary LP and 631 shoulders undergoing salvage LP. Statistically significant differences in favor of primary LP were found in 2 of the 11 and 2 of 4 included studies in terms of recurrent instability and returning to the same sports (RTS) at preinjury level, respectively. In terms of the visual analog scale, subjective shoulder value and the Western Ontario Shoulder Instability Index, 2 of the 4, 1 of the 3 and 1 of the 3 included studies reported statistically significant differences in favor of primary LP. Differences were not noticed regarding complications, reoperations, the time to RTS, the Rowe score, the Athletic Shoulder Outcome Scoring System, and forward flexion.
CONCLUSIONS: Current evidence suggests that compared with primary LP, salvage LP may provide inferior postoperative outcomes in terms of recurrent instability and the rate of RTS at preinjury level. Primary and salvage LP may yield comparable efficacy in terms of complications, reoperations, the rate of RTS, the time to RTS, pain, shoulder function, and range of motion.

UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

UNASSIGNED: To summarize mid-term effectiveness of modified arthroscopic suture button fixation Latarjet procedure for treatment of recurrent anterior shoulder dislocations.
UNASSIGNED: Between January 2018 and October 2020, 30 patients with recurrent anterior shoulder dislocations were treated with modified arthroscopic suture button fixation Latarjet procedure. There were 19 males and 11 females with an average age of 27.3 years (range, 18-41 years). The shoulder dislocation occurred 3-7 times, with an average of 4.9 times. The time from the last dislocation to operation was 3-10 days, with an average of 4.1 days. Glenoid defects exceeded 20% in all cases. There were 27 cases of Hill-Sachs lesions. The joint pain and function were estimated by visual analogue scale (VAS) score, University of California, Los Angeles (UCLA) score, Rowe score, American Association for Shoulder and Elbow Surgery (ASES) score, Walch-Duplay score, and the range of external rotation at 0° and external rotation at 90° abduction of shoulder before operation and at 1 month, 6 months, and last follow-up. The X-ray film, CT scan and three-dimensional reconstruction were reviewed to observe the position, healing, and absorption of the coracoid graft, correction of glenoid defect, and joint degeneration.
UNASSIGNED: The operation time ranged from 51 to 79 minutes, with an average of 68.4 minutes. All incisions healed without complications such as nerve or blood vessel injury. All patients were followed up 36-60 months with an average of 44.6 months. The VAS score, UCLA score, Rowe score, ASES score, Walch-Duplay score, and the range of external rotation at 0° and external rotation at 90° abduction after operation significantly improved when compared with preoperative values ( P<0.05). All indicators further improved with time, and the differences between different time points after operation were significant ( P<0.05). Imaging review showed that the coracoid graft was located in the anteroinferior glenoid at 1 day after operation, and no occurrence of shoulder osteoarthritis was found during follow-up. The anatomical structure of the glenoid was normal, and no delayed healing or non-union of the coracoid graft occurred. At 20 months after operation, arthroscopic re-exploration was performed in 1 case due to fracutre caused by falling injury revealed the good shaping of the coracoid graft, smooth glenoid, and no bone resorption or osteoarthritis.
UNASSIGNED: For recurrent anterior shoulder dislocations, the modified arthroscopic suture button fixation Latarjet procedure can obtain good recovery of shoulder function and low incidence of complications and has a good mid-term effectiveness.

UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: 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.

UNASSIGNED: The clinical data of 15 patients with severe bone defects and anterior shoulder instability treated with suture button fixation Latarjet procedure under total arthroscopy between June 2020 and February 2023 was retrospectively analyzed, including 11 males and 4 females, with an average age of 31.1 years (range, 20-54 years). Three-dimensional CT showed that the average glenoid bone defect was 24.4% (range, 16.3%-35.2%). The average number of shoulder dislocation was 4.2 times (range, 3-8 times). The disease duration ranged from 6 to 21 months with an average of 10.6 months. The operation time and intraoperative blood loss were recorded. The pain relief was evaluated by visual analogue scale (VAS) score, and the functional recovery of shoulder joint was evaluated by Rowe score, Walch-Duplay score, and American Association for Shoulder and Elbow Surgery (ASES) score before and after operation. The range of motion (ROM) of the shoulder joint was assessed, including active flexion, lateral external rotation, abduction 90° external rotation, and internal rotation. Three-dimensional CT was performed at 6 months after operation and at last follow-up to observe the absorption of bone graft, the position of bone graft and glenoid, and the healing of bone graft.
UNASSIGNED: The operation was successfully completed in all patients. The operation time was 85-195 minutes, with an average of 123.0 minutes. The intraoperative blood loss was 20-75 mL, with an average of 26.5 mL. All patients were followed up 13-32 months, with an average of 18.7 months. During the follow-up, there was no serious complication such as shoulder joint infection, joint stiffness, or vascular and nerve injury. One patient had partial absorption of the transplanted bone and bone nonunion at 3 months after operation, but the pain of the shoulder joint relieved at last follow-up, and no redislocation of the shoulder joint occurred; no obvious bone fracture or dislocation of the shoulder joint was found in the other patients. Bone union was achieved at 6 months during follow-up. At last follow-up, the VAS score, Rowe score, Walch-Duplay score, and ASES score significantly improved when compared with those before operation ( P<0.05), while the ROM of active flexion, lateral external rotation, abduction 90° external rotation, and internal rotation of the shoulder joint was not significantly different from those before operation ( P>0.05).
UNASSIGNED: Suture button fixation Latarjet procedure under total arthroscopy can improve shoulder joint function in patients with severe anterior shoulder instability caused by bone defects, and imaging also indicates satisfactory placement of transplanted bone blocks.

UNASSIGNED: To evaluate the early-term effectiveness of Latarjet procedure with double EndoButtons fixation for recurrent anterior shoulder dislocation by coracoid osteotomy with preserving coracoacromial ligament.
UNASSIGNED: Between January 2021 and June 2023, 19 patients with recurrent anterior shoulder dislocations were treated by arthroscopic Latarjet procedure with double EndoButtons fixation, all of which underwent coracoid osteotomy with preserving the coracoacromial ligament. There were 11 males and 8 females, with an average age of 23.3 years (range, 17-32 years). Shoulder dislocations ranged from 3 to 11 times, with an average of 6.4 times. The disease duration ranged from 3 to 35 months, with an average of 12.9 months. All apprehension tests were positive. Imaging examination showed that the defect width of the ipsilateral glenoid bone was 13%-26%, with an average of 19.8%. After operation, the shoulder range of motion was examined, including flexion lift, lateral external rotation, extension 90° external rotation, and internal rotation. Shoulder joint function was evaluated by Walch-Duplay score, American Association for Shoulder and Elbow Surgery (ASES) score, and Rowe score. Imaging examinations were taken to observe the position and shaping of coracoid.
UNASSIGNED: All incisions healed by first intention and no nerve or vessel injury occurred. All patients were followed up 9-24 months (mean, 14.5 months). There was no recurrence of shoulder dislocation and the apprehension tests were negative during follow-up. There was no significant difference in the shoulder range of motion (flexion lift, lateral external rotation, extension 90° external rotation, and internal rotation) between preoperation and at last follow-up ( P>0.05). The Walch-Duplay score, ASES score, and Rowe score significantly improved when compared with those before operation ( P<0.05). Postoperative imaging showed that coracoid graft was at the same level with the glenoid in all cases; the center of coracoid graft was located between 3 to 5 o\'clock. During follow-up, there was no glenohumeral joint degeneration, the acromiaohumeral distance was not reduced when compared with preoperation, and the coracoid bone gradually formed concentric circles with the humeral head.
UNASSIGNED: The Latarjet procedure with double EndoButtons fixation can effectively treat recurrent anterior shoulder dislocation by coracoid osteotomy with preserving coracoacromial ligament, and the early-term effectiveness is satisfactory.

UNASSIGNED: To evaluate the mid-term effectiveness of limited unique coracoid osteotomy suture button fixation Latarjet (LU-tarjet) procedure in treatment of recurrent anterior shoulder dislocation.
UNASSIGNED: Between March 2017 and February 2019, 56 patients with recurrent shoulder dislocation were treated with arthroscopic LU-tarjet procedure. There were 44 males and 12 females with an average age of 26.3 years (range, 18-41 years). Shoulder joint dislocation occurred 2-16 times, with an average of 7.5 times. The time from the initial dislocation to operation ranged from 6 months to 13 years, with a median of 4.6 years. Preoperative shoulder joint fear test and re-reduction test were positive in all patients. The Beighton score of joint relaxation ranged from 1 to 7, with an average of 4.1. The shoulder Instability Severity Index Score (ISIS) ranged from 5 to 10, with an average of 7.8. The size of glenoid defects on the affected side ranged from 15% to 32% (mean, 22.4%). All patients had Hill-Sachs injuries of varying degrees. Six patients had re-dislocation after Bankart surgery. The operation time, incision healing, and postoperative complications were recorded. The range of motion (shoulder flexion, extension, abduction, external rotation, 90° external rotation, and internal rotation) and muscle strength in shoulder flexion, abduction, external rotation, and internal rotation) of shoulder joint were compared between pre- and post-operation. The improvement of shoulder function was evaluated using the American Association for Shoulder and Elbow Surgery (ASES) score, Walch-Duplay score, and Rowe score. X-ray films and three-dimensional CT were used to analyze the location, healing, and remolding of bone graft, the repair of glenoid defect, and degenerative changes of the shoulder joint.
UNASSIGNED: All operations were successfully completed. The operation time ranged from 42 to 98 minutes, with an average of 63 minutes. All incisions healed by first intention. All patients were followed up 5-7 years (mean, 6.3 years). During follow-up, 2 patients experienced shoulder subluxation within 1 year after operation and 1 patient experienced recurrent shoulder joint pain. The remaining patients had no related complications. At last follow-up, there was no significant difference between the two groups ( P>0.05) in range of motion (shoulder flexion, extension, abduction, external rotation, 90° external rotation, and internal rotation) and muscle strength in shoulder flexion, abduction, external rotation, and internal rotation). The ASES score, Rowe score, and Walch-Duplay score of shoulder significantly improved when compared with those before operation ( P<0.05). Postoperative CT showed that 53 cases (94.64%) of coracoid bone masses were centered placed vertically, 2 cases (3.57%) were superior, and 1 case (1.79%) was inferior; 49 cases (87.50%) of the coracoid bone grafts were flush with the glenoid, 2 cases (3.57%) and 5 cases (8.93%) were medially and laterally positioned. The volume of coracoid bone graft decreased first and then increased, and the shape of the bone graft was continuously remodeling and gradually matched with the track of the humerus head (the optimal circle of the glenoid), all coracoid bone grafts healed. At last follow-up, the coverage rate of optimal glenoid circle was 89.6%-100%, with an average of 97.4%. The area of glenoid defect was 2.6%±1.3%, which significantly decreased when compared with preoperative (22.4%±5.4%) ( P<0.05). At last follow-up, no obvious degenerative changes of shoulder joint was observed.

UNASSIGNED: To review the development and research progress of suture button fixation Latarjet procedure.
UNASSIGNED: A comprehensive literature review was conducted to summarize the development and related modified techniques of the suture button fixation Latarjet procedure.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 综述弹性固定Latarjet手术发展历程及研究进展。.
UNASSIGNED: 查阅国内外弹性固定Latarjet手术相关研究文献，对该术式发展历程及相关改良技术进行总结。.
UNASSIGNED: 自1954年法国Latarjet教授首次提出Latarjet手术以来，该术式经历了3次关键变革，并逐渐形成了弹性固定Latarjet手术。目前临床应用结果显示弹性固定Latarjet手术治疗复发性肩关节脱位可获得满意疗效，但是仍存在移植骨块与周围组织撞击、手术破坏喙肩弓及胸小肌等解剖结构等不足。为了进一步减少移植骨块撞击带来的并发症、降低盂肱关节接触压力、消除手术对于肩关节原有生理结构的影响，学者们在其基础上提出了使用 FiberTape Cerclage 的关节镜下弹性固定 Latarjet 手术、一致弧Latarjet手术合并重建喙肩韧带、喙突有限截骨线袢固定Latarjet手术（LU-tarjet手术）等相关改良技术，临床应用也获得较好疗效。同时，关节镜下改良嵌入式喙突移位手术（Cuistow手术）、特殊关节盂骨移植技术、关节镜自体髂嵴骨移植术等关节盂重建改良技术也具有良好疗效。但是，目前尚缺乏各项技术的远期随访结果以及各项技术之间的对比研究。.
UNASSIGNED: 弹性固定Latarjet手术是治疗复发性肩关节脱位的有效术式，有多种改良术式，但尚无公认“金标准”，需要进一步进行临床及基础研究。.

UNASSIGNED: A multicenter, double-blinded randomized controlled trial comparing isolated Bankart repair (NO REMP) to Bankart repair with remplissage (REMP) reported benefits of remplissage in reducing recurrent instability at 2 years postoperative. The ongoing benefits beyond this time point are yet to be explored.
UNASSIGNED: To (1) compare medium-term (3 to 9 years) outcomes of these previously randomized patients undergoing isolated Bankart repair (NO REMP) or Bankart repair with remplissage (REMP) to manage recurrent anterior glenohumeral instability; (2) examine the failure rate, overall recurrent instability, and reoperation rate.
UNASSIGNED: Randomized controlled trial; Level of evidence, 1.
UNASSIGNED: Recruitment and randomization for the original randomized trial occurred between 2011 and 2017. Patients ≥14 years diagnosed with recurrent traumatic anterior shoulder instability with an engaging Hill-Sachs defect of any size were included. Those with a glenoid defect >15% were excluded. In 2020, participants were contacted by telephone and asked standardized questions regarding ensuing instances of subluxation, dislocation, or reoperation on their study shoulder. \"Failure\" was defined as a redislocation, and \"overall recurrent instability\" was described as a redislocation or ≥2 subluxations. Descriptive statistics, relative risk, and Kaplan-Meier survival curve analyses were performed.
UNASSIGNED: A total of 108 participants were randomized, of whom 50 in the NO REMP group and 52 in the REMP group were included in the analyses in the original study. The mean number of months from surgery to the final follow-up was 49.3 and 53.8 months for the NO REMP and REMP groups, respectively. Failure rates were 22% (11/50) in the NO REMP group versus 8% (4/52) in the REMP group. Rates of overall recurrent instability were 30% (15/50) in the NO REMP group versus 10% (5/52) in the REMP group. Survival curves were significantly different, favoring REMP in both scenarios.
UNASSIGNED: For the treatment of traumatic recurrent anterior shoulder instability with a Hill-Sachs lesion and subcritical glenoid bone loss (<15%), a significantly lower rate of overall postoperative recurrent instability was observed with arthroscopic Bankart repair and remplissage than with isolated Bankart repair at a medium-term follow-up (mean of 4 years). Patients who did not receive a remplissage experienced a failure (redislocated) earlier and had a higher rate of revision/reoperation than those who received a concomitant remplissage.
