Objective To summarize the research progress of surgical treatment for anterior shoulder dislocation and combined injuries. Methods The related literature was reviewed, and the surgical treatment options for the anterior shoulder dislocation and its combined injuries were summarized. Results Anterior shoulder dislocation can combine with anteroinferior capsular ligament complex injury (Bankart injury), bony Bankart defect, and Hill-Sachs lesion. For Bankart and bony Bankart injuries, arthroscopic repair or coracoid osteotomy combined with bony graft reconstruction can be performed. For Hill-Sachs lesion, conservative treatment, soft tissue repair, or bony reconstruction should be selected based on the extent of the bone defect. For bipolar injury, the Bankart repair, Remplissage, or arthroplasty should be selected based on the extent of the glenoid defect. Conclusion With the development of arthroscopy and the improvement of the surgical concept, there is a complete set of surgical options for various injuries of the anterior shoulder dislocation. When choosing a surgical procedure, the patient’s specific injury and age, exercise level, and other relating factors should be comprehensively assessed in order to achieve the best results.
Objective To explore the research progress of the coracoid transfer surgery using suture button fixation, particularly focusing on the technique known as Chinese unique Inlay Bristow (Cuistow surgery).MethodsExtensive literature review was conducted to summarize and analyze the utilization of suture button fixation in the Cuistow surgery, comparing its biomechanical and clinical outcomes with those of traditional screw fixation.Results Utilizing suture button fixation in coracoid transfer surgery helps circumvent certain metal-related complications associated with traditional screw fixation. While its biomechanical stability and effectiveness have been preliminarily confirmed, debates persist regarding its graft healing rate and postoperative recurrence rate compared to traditional screw fixation. The Cuistow surgery based on the Inlay structure is a solution to improve the healing rate of graft after suture button fixation. Conclusion Suture button fixation, as a novel approach in coracoid transfer surgery, remains to have its advantages and disadvantages compared to traditional screw fixation not entirely elucidated, underscoring the need for further in-depth clinical and fundamental research. Cuistow surgery is the Chinese experience of coracoid transfer surgery, and its biomechanical stability and clinical advantages have been preliminarily confirmed.
ObjectiveTo review the research progress of the biomechanical study of the Bristow-Latarjet procedure for anterior shoulder dislocation. MethodsThe related biomechanical literature of Bristow-Latarjet procedure for anterior shoulder dislocation was extensively reviewed and summarized. ResultsThe current literature suggests that when performing Bristow-Latarjet procedure, care should be taken to fix the bone block edge flush with the glenoid in the sagittal plane in the direction where the rupture of the joint capsule occurs. If traditional screw fixation is used, a double-cortical screw fixation should be applied, while details such as screw material have less influence on the biomechanical characteristics. Cortical button fixation is slightly inferior to screws in terms of biomechanical performance. The most frequent site of postoperative bone resorption is the proximal-medial part of the bone block, and the cause of bone resorption at this site may be related to the stress shielding caused by the screw. ConclusionThere is no detailed standardized guidance for bone block fixation. The optimal clinical treatment plan for different degrees of injury, the factors influencing postoperative bone healing and remodeling, and the postoperative osteoarticular surface pressure still need to be further clarified by high-quality biomechanical studies.
ObjectivesTo systematically review the epidemiological characteristics of post-stroke shoulder pain (PSSP).MethodsPubMed, WanFang Data, CNKI, EMbase, The Cochrane Library and SinoMed databases were electronically searched to collect studies on the morbidity of PSSP from inception to November 30th, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using Stata 15.0 software.ResultsA total of 13 studies were included. The total sample size was 3 514, including 1 357 patients with PSSP. The results of meta-analysis showed that the total morbidity of PSSP was 45.0% with 95%CI 32.0% to 58.0%. The results of subgroup analysis showed that the morbidity of PSSP was 55.5% (95%CI 48.1% to 63.0%) prior to 2010 and 40.6% (95%CI 28.3% to 52.9%) after 2010, respectively. The morbidity of PSSP in Asia was 61.2% (95%CI 51.3% to 71.1%), and in Europe and America was 18.4% (95%CI 9.9% to 26.9%), respectively.ConclusionsCurrent evidence suggests that PSSP has high morbidity, and it may be affected by regional factors. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective
To evaluate the efficacy and safety of different site injection of compound betamethasone injection, ropivacaine and sodium hyaluronate for treatment of frozen shoulder at early stage.
Methods
A Total of 68 participants were included from May 2015 to May 2017 and randomly assigned to the glenohumeral joint and subacromial space group (IA+SA group, n=34) and glenohumeral joint group (IA group, n=34). In the IA+SA group, a solution of 1 mL corticosteroid, 6 mL ropivacaine, 2 mL sodium hyaluronate, and 8 mL normal saline were prepared and injected to glenohumeral joint, and a solution of 1 mL corticosteroid, 2 mL ropivacaine, 2 mL sodium hyaluronate, and 2 mL normal saline were injected to subacromial space. In the IA group, participants were given the same dose of drugs to the glenohumeral joint. The Visual Analogue Scale (VAS) score and Constant-Murley score were used to assess pain and function of shoulder respectively. The change of VAS score and Constant-Murley score after treatment were used to evaluate pain relief and shoulder function improvement.
Results
Of the 68 participants, two in each group were lost to follow up and one in the IA+SA group dropped out. There was significant effect on pain relief and shoulder function improvement on all measurement in both groups (P<0.001) during the 12 weeks after treatment. In the IA group, group- by-time interaction were significant for pain relief at 6 and 12 weeks comparing with that at 3 weeks (P<0.001), while no significant difference at 6 weeks comparing with 12 weeks. In the IA+SA group, group-by-time interaction were significant for pain relief at all endpoints (3 weeksvs. 6 weeks: P<0.001; 3 weeksvs. 12 weeks: P<0.001; 3 weeksvs. 6 weeks: P=0.034). In both groups, there was significant effect on shoulder function improvement when compared at each endpoint within group (P<0.001). Between-group comparison revealed no significant effect on pain relief (P=0.386) or shoulder function improvement (P=0.685). There was also no significant effect on pain relief (3 weeks: P=0.898; 6 weeks: P=0.448; 12 weeks: P=0.216) and shoulder function improvement (3 weeks: P=0.120; 6 weeks: P=0.152; 12 weeks: P=0.868) at each same endpoint.
Conclusions
Different site injection can effectively release pain and improve shoulder function for the patients with frozen shoulder at early stage and be well tolerated. However, it is not found that two site injection is inferior to single site injection.
Objective To investigate the mid-term effectiveness of arthroscopic Bankart repair for recurrent anterior shoulder dislocation. Methods The clinical data of 107 patients with recurrent anterior shoulder dislocation who met the inclusion criteria between January 2017 and June 2021 was retrospectively analyzed, and all patients underwent arthroscopic Bankart repair. There were 88 males and 19 females. The age of the primary dislocation ranged from 13 to 48 years (mean, 23.3 years). The number of preoperative dislocations was 2-160 times (median, 7 times). The duration of preoperative instability was 0.2-240.0 months (median, 36.0 months). The mean age at operation was 28.2 years (range, 16-61 years). There were 43 cases of left shoulder and 64 cases of right shoulder. The proportion of glenoid defects in 63 patients was 1.7%-16.1% (mean, 8.1%). MRI showed that none of the patients had rotator cuff tears or shoulder stiffness. The CT three-dimensional reconstruction was performed at 1 day after operation to evaluate the distribution of implanted anchors and the occurrence of glenoid split fracture and whether there were nails pullout at the implant site. The postoperative complications were observed, and the pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, Rowe score, Constant-Murley score, and American Shoulder and Elbow Surgeons (ASES) score. The recurrence of instability, the results of apprehension test, the number of patients who returned to preoperative sports level, and the satisfaction rate of patients were recorded. Results All patients were successfully operated and were followed up 20-73 months (mean, 41.5 months). All incisions healed by first intention. The CT three-dimensional reconstruction at 1 day after operation showed that the anchors were located at the 2 : 00-5 : 30 positions of the glenoid, and there was no glenoid split fracture or nails pullout at the implant site. At last follow-up, VAS score was significantly lower than that before operation, and Rowe score, Constant-Murley score, and ASES score were significantly higher than those before operation (P<0.05). Seven patients (6.5%) had recurrence of anterior shoulder dislocation at 23-55 months (mean, 39.9 months) after operation, including 6 cases of dislocation and 1 case of subluxation. At last follow-up, 51 patients (47.7%) returned to preoperative sports level, and 11 patients (10.3%) had a positive apprehension test. The patients’ satisfaction rate was 90.7% (97/107). Among the 10 patients who were not satisfied with the surgical effectiveness, 7 patients had postoperative recurrence of instability, and 3 patients felt that they did not return to preoperative sports level. Conclusion Arthroscopic Bankart repair has good mid-term effectiveness in patients with recurrent anterior shoulder dislocations, minimal or no glenohumeral bone defects and low sports need.
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.
Frozen shoulder is a common disease in orthopaedic clinic. The main clinical manifestations were shoulder joint pain and limited active and passive activity. However, the etiology and pathogenesis of frozen shoulder are not fully understood, so people can not choose the appropriate treatment plan. In recent years, there have been a lot of exploration on the pathogenesis and treatment measures of this disease at home and abroad, but there is no unified standard for the treatment of frozen shoulder. This article summarizes the treatment methods of frozen shoulder at home and abroad in recent years, analyzes the advantages and disadvantages of non-surgical treatment and surgical treatment, in order to provide assistance for clinical practice.
Objective To systematically evaluate the effect of arm sling on shoulder subluxation in stroke patients with hemiplegia. METHODS CNKI, Wanfang, VIP, PubMed, Web of Science, Embase, Cochrane Library, OVID, EBM Reviews, Best Practice, ACP Journal Club, and Practice Guidline were searched from establishment to March 2023. The literature on randomized controlled trials of arm sling on gait or balance in post-stroke patients with hemiplegia were included. RevMan 5.4.1 software was used for meta-analysis. Results A total of 13 articles were included, including 691 subjects, 343 in the experimental group, and 348 in the control group. The meta-analysis results showed that patients wearing the boom arm were effective in improving the recovery of upper extremity function [mean difference (MD)=8.12, 95% confidence interval (CI) (2.39, 11.60), P＜0.000 01], relieving pain due to shoulder subluxation [MD=?1.13, 95%CI (?1.70, ?0.56), P=0.000 1], and enhancement of patients’ quality of life in daily activities [MD=15.07, 95%CI (3.24, 26.90), P=0.01], all of which were superior to the control group. However, there was no statistically significant difference between the two groups in terms of Apnea-Hypopnea Index [MD=?1.86, 95%CI (?3.79, 0.06), P=0.06], 6 min walking test [MD=?0.51, 95%CI (?18.52, 17.49), P=0.96], 10 meter walk time [MD=0.00, 95%CI (?0.06, 0.06), P=0.91], heart rate [MD=?0.22, 95%CI (?5.10, 4.27), P=0.93], and Berg balance scale [MD=?2.53, 95%CI (?8.17, 3.10), P=0.38]. Conclusion The use of arm sling can effectively improve patients’ quality of life, functional recovery of the upper limbs and reduce pain, providing an evidence-based basis for healthcare professionals to treat patients with proven treatment modalities.
ObjectiveTo summarize the diagnosis and measurement methods of bone defect in anterior shoulder instability (glenoid bone defect and Hill-Sachs lesion).MethodsThe related literature on the diagnosis and measurement of the bone defect in anterior shoulder instability was reviewed and summarized.ResultsThe commonly used techniques for the diagnosis of anterior glenoid bone defect and Hill-Sachs lesion of humeral head include X-ray, CT, MRI, arthroscopy, arthrography. The methods for measuring the degree of anterior glenoid bone defect include Griffith method, glenoid index method, Pico method, and best-fit circle method. The indexes for measuring the Hill-Sachs lesion include the length, width, depth, and volume. X-ray is mainly used for primary screening. Best-fit circle method on three-dimensional (3D) CT reconstruction is commonly used to measure the glenoid bone defect currently. Glenoid track theory on 3D CT reconstruction is popular in recent years. Reliability of measuring the glenoid bone defect and Hill-Sachs lesion with MRI and arthroscopy is still debatable. Arthrography is more and more used in the diagnosis of shoulder joint instability of bone defect and concomitant soft tissue injury.ConclusionHow to improve the accuracy of evaluating glenoid bone defect and Hill-Sachs lesion before surgery still need further study.
