Usefulness of the acromioclavicular joint cross-sectional area as a diagnostic image parameter of acromioclavicular osteoarthritis

BACKGROUND Acromioclavicular joint(ACJ)space narrowing has been considered to be an important diagnostic image parameter of ACJ osteoarthritis(ACJO).However,the morphology of the ACJ space is irregular because of osteophyte formation,subchondral irregularity,capsular distention,sclerosis,and erosion.Therefore,we created the ACJ cross-sectional area(ACJCSA)as a new diagnostic image parameter to assess the irregular morphologic changes of the ACJ.AIM To hypothesize that the ACJCSA is a new diagnostic image parameter for ACJO.METHODS ACJ samples were obtained from 35 patients with ACJO and 30 healthy individuals who underwent shoulder magnetic resonance(S-MR)imaging that revealed no evidence of ACJO.Oblique coronal,T2-weighted,fat-suppressed SMR images were acquired at the ACJ level from the two groups.We measured the ACJCSA and the ACJ space width(ACJSW)at the ACJ on the S-MR images using our imaging analysis program.The ACJCSA was measured as the cross-sectional area of the ACJ.The ACJSW was measured as the narrowest point between the acromion and the clavicle.RESULTS The average ACJCSA was 39.88±10.60 mm;in the normal group and 18.80±5.13 mm;in the ACJO group.The mean ACJSW was 3.51±0.58 mm in the normal group and 2.02±0.48 mm in the ACJO group.ACJO individuals had significantly lower ACJCSA and ACJSW than the healthy individuals.Receiver operating characteristic curve analyses demonstrated that the most suitable ACJCSA cutoff score was 26.14 mm^(2),with 91.4%sensitivity and 90.0%specificity.CONCLUSION The optimal ACJSW cutoff score was 2.37 mm,with 88.6%sensitivity and 96.7%specificity.Even though both the ACJCSA and ACJSW were significantly associated with ACJO,the ACJCSA was a more sensitive diagnostic image parameter.

Clinical study on treatment of TOSSY type III acromioclavicular joint dislocation with clavicular hook plate combined with coracoclavicular ligament repair

Objective:To explore the treatment of TOSSY type III acromioclavicular joint dislocation with clavicular hook plate combined with coracoclavicular ligament repair and its clinical effect.Methods:80 patients with TOSSY type III acromioclavicular joint dislocation who were admitted to our hospital from January 2014 to January 2019 were selected.They were randomly divided into the control group(n=39,treated with clavicular hook plate)and the observation group(n=41,treated with clavicular hook plate combined with coracoclavicular ligament repair)by the random number table method.The clinical efficacy in 12 months after operation,related clinical indicators,12-month postoperative recovery and postoperative complications were compared between the two groups.Results:The excellent and good rate was 92.68%(38/41)in 12 months after operation in the observation group,which was higher than that(76.92%,30/39)in the control group(p<.05).There were no significant differences in the duration of surgery,intraoperative blood loss and HLOS between the observation group and the control group(p>.05).In 12 months after operation,abduction activity and forward flexion activity of the observation group were higher than those of the control group,and visual analogue score(VAS)was lower than that of the control group(p<.05).The incidence of complications in the observation group was slightly lower than that in the control group,but there was no statistically significant difference between the two groups(p>.05).Conclusions:For TOSSY type III acromioclavicular joint dislocation,clavicular hook plate combined with coracoclavicular ligament repair has a good clinical efficacy.It can improve shoulder joint function,alleviate shoulder pain and have fewer complications.It can provide a reference for clinical treatment of this type of acromioclavicular joint dislocation.

Treatment of patients with acromioclavicular joint injuries(Rockwood II-VI) with modeled Kirschner wire and cortical screw

Objective: To propose an original method of surgical treatment for the acromial extremity of the clavicle rupture(Rockwood II-VI) with modeled Kirschner wire and cortical screw. Methods: Anatomical study and a test method were applied to 43 cadavers of both sexes. During the period between 2000 and 2013, 34 patients of both sexes were operated upon using the new method. In the comparison group(n = 120), the fixation of the acromial extremity of the clavicle rupture was performed with hamate plate, Lee hook and Kirschner wires.Results: Its application allows, according to the evaluation scale of Constant and Murley(1987), 10% more preservation of the function of the shoulder compared with traditional methods of surgical treatment, and shortens the required hospital treatment and temporary disability periods.Conclusions: It is shown that the proposed author's method combines low invasiveness, minimum dimensions of the construction and low-cost treatment.

Posterior Positioning of a Clavicle Hook Plate Is a Risk Factor for Acromial Fractures after Acromioclavicular Joint Dislocation

Purpose: Acromioclavicular (AC) joint dislocation is commonly treated using a clavicle hook plate (HP). However, previous reports have indicated that acromial fractures may occur after HP fixation. The purpose of this study was to identify risk factors for acromial fractures. Methods: A retrospective study was conducted on 39 patients with AC joint dislocation who were treated using clavicle HP fixation in our hospital between 2006 and 2017. Related parameters, including Rockwood classification, hook angle, the degree of reduction, the coverage of the hook under the acromion, and the anteroposterior position of the hook under the acromion, were evaluated to identify risk factors for acromial fractures. Results: The mean age of the participants was 51.7 (range 19 - 81) years;34 were men and 5 were women. Injury occurred on the right side in 18 patients and on the left side in 21. Injuries were categorized as follows: 24 were Rockwood type III, one was type IV, and 14 were type V. Four of the 39 patients (10%) experienced acromial fractures. Statistical analyses indicated that the degree of reduction at the final follow-up was moderately correlated with the Constant score. Posterior positioning of the hook was the only identified risk factor for acromial fractures. Hook angle and the degree of reduction at the time of surgery were not significantly associated with acromial fractures. Conclusions: Postoperative shoulder function was associated with the degree of reduction at the final follow-up, suggesting that anatomical reduction is recommended for AC joint dislocation. Posterior positioning of the hook is a risk factor for acromial fractures;however, clavicle HP fixation provides a positive outcome for AC joint dislocation. Therefore, careful positioning of the hook is required for preventing acromial fractures.

Comparison of Surgical Techniques Used in Treating Acromioclavicular Dislocation in Patients Participating in Sports: A Systematic Review

Introduction: The acromioclavicular joint is a superficial diarthrodial joint that surrounds the medial articular facet of the acromion and the distal portion of the clavicle. Due to its anatomy and biomechanics, it is highly susceptible to trauma and in young men who play contact sports, acromioclavicular dislocation is common. This article aimed to systematically review the literature and compare the surgical techniques used in the treatment of acromioclavicular dislocation in patients who practice sports. Methods: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Eligible studies for this systematic review included articles in English or Spanish published between 2013 and 2023, which mention the occurrence of acromioclavicular dislocation during sports practices. Additionally, only studies that addressed the surgical treatment of acromion-clavicular dislocation and contained original data on the topic were included. Results: We found 144 eligible studies after searching the LILACS and PubMed databases. Based on the inclusion and exclusion criteria and the reviewers’ consensus, we selected four studies for the systematic review. 133 patients with AC joint displacement were evaluated. Mean Age: approximately 31.90 years. 81.92 of these injuries occurred during sports practice. Surgical Procedures Used: titanium plates fixation (49 patients), arthroscopy (24), single tunnel technique (30) and coracoid sling technique (30). The results of the visual analog scale and Constant-Murley scores varied between the techniques used. Twenty-two complications after surgical treatment were identified. Conclusion: A significant variability of operative techniques can be used in the surgical approach of acromioclavicular dislocation, such as arthroscopy, single tunnel, coracoid sling and titanium plates. Although it presented excellent functional results compared to the other three techniques evaluated by this review, using titanium plates is not the gold standard since other techniques not assessed by this work may be more effective.

Comparative study on treating complete dislocation of acromioclavicular joint with three different methods

Objective:To comparatively study complete dislo cation of acromioclavicular joint treated with three different methods. Methods:A total of 96 patients (81 males and 15 females, aged 16-59 years, mean=45 years) with complete dislocation of acromioclavicular join t were treated with Dewars operation (Group A, n=32), internal fixation with K irschner tension band wires (Group B, n=44), or internal fixation with Wolter pl ates (Group C, n=20), respectively, in this study. Eighty-five patients suffere d from acute dislocations and eleven from chronic dislocations. Results:The patients were followed up for 50 months on an aver age. According to Karlssons standard, in Group A, 26 patients were assessed as good, 5 as fair and 1 as poor. In Group B, 20 patients were assessed as good, 1 3 as fair and 11 as poor. In Group C, 15 patients were assessed as good, 4 as fa ir and 1 as poor. The good and fair rates were significantly different between G roup A and Group B, and between Group C and Group B, but no statistical differen ce was found between Group A and Group C. The operating time was ( 52.36 ± 7 .24 ) minutes, ( 67.43 ± 8.11 ) minutes and ( 69.73 ± 8.04 ) minutes in Groups A, B and C, respectively. And the hospitalizing fees were ( 2 400 ± 270) yuan, ( 2 100 ±190) yuan and ( 8 450 ±360) yuan in Groups A, B and C, respectively. Conclusions:Dewars operation is a good and safe method with shorter operating time and lower hospitalizing fee for treating complete disloca tion of acromioclavicular joint. The method is simple without the need of a seco nd operation to remove the implants and with few complications.

Operative treatment of acromioclavicular joint dislocation：a new technique with suture anchors

Objective：To evaluate clinical outcome of suture anchors in strengthening both acromioclavicular and coracoclavicular ligaments in the surgical treatment of acromioclavicular joint dislocation.Methods：Twenty-eight patients with acute traumatic Rockwood Ⅲ,Ⅳ and Ⅴ dislocations of the acromioclavicular joint surgically treated at our institute between October 2010 and January 2012 were recruited.All patients underwent open reduction combined with suture anchors.Function was evaluated using the ConstantMurley shoulder score.Clinical and radiographic shoulder ratings were evaluated using Taft criteria at 3,6 and 12 months.Results：Two cases with fixation loosening were not included in final statistical analysis.Other patients obtained full joint reposition on immediate postoperative radiographs.Follow-up was performed with an average of 15.6 months （range,12-19）.After early range of motion exercises,96.2％ of the patients （25/26） could abduct and elevate their shoulders more than 90 degrees within postoperative 3 months.There was no infection.Average Constant-Murley score was 96.3 points （range,94-100）and mean Taft shoulder rating was 10.7 points （range,8-12） at 12 months.Conclusion：The suture anchor is a relatively simple technique and can avoid screw removal which is helpful in reconstructing both acromioclavicular and coracoclavicular ligaments in acute traumatic acromioclavicular joint dislocation.

A modified method of coracoid transposition for the treatment of complete dislocation of acromioclavicular joint

Objective: To report a new method of coracoid transposition for the treatment of complete dislocation of acromioclavicular joint and to evaluate its efficacy. Methods: We modified Dewar’s surgical method as follows: (1) Two small incisions, a transversal incision on the acromioclavicular joint and a longitudinal incision on the coracoid, were made instead of a conventional large arc incision from the acromion to coracoid. (2) The foreign body in the acromioclavicular joint was cleared out. The chondral surface at the lateral segment of clavicle was resected to form a pseudarthrosis and meanwhile the residual joint capsule and ligaments were repaired. (3) The coracoid was moved to the anteroinferior edge of the clavicle instead of the anterior margin and (4) the coracoid was moved to the lateral border of the clavicle instead of the superior border of the coracoclavicular ligament. Results: The follow up duration in 30 patients of the series was from 6 to 72 months (mean 41 months). Functional assessment was carried out by the criteria delineated previously by Karkson, in which Grade A was in 24 cases, Grade B in 4cases, and C in 2. Conclusions: This modified technique, having less postoperative complications and less injuries to tissues and according well with the requirement of biomechanics, can achieve a stable reduction of acromioclavicular joint with a good functional and cosmetic result and therefore is preferable to use clinically on a large scale.

定量CT测定锁骨远端骨密度分区指导肩锁关节脱位重建的价值

背景:肩锁关节脱位喙锁韧带重建在锁骨侧骨隧道的最佳位置尚未达成共识,且术后会发生锁骨侧骨隧道扩大、骨溶解、锁骨骨折、内固定失效等并发症。骨密度在内植物固定强度及稳定性上起重要作用,锁骨远端骨密度的区域差异在肩锁关节脱位修复重建中不应被忽视,目前临床上尚无人体有关锁骨远端骨密度的定量研究。目的:通过定量CT测量锁骨远端不同区域骨密度的大小,为外科医生修复重建喙锁韧带提供参考。方法:对2022年10-12月在安徽医科大学附属阜阳人民医院(阜阳市人民医院)行定量CT检查的101例患者1616份亚分区进行锁骨远端骨密度测量。对于每个定量CT样本,首先由内侧向外侧划分锁骨远端为以下4个区域,即锥状结节区(A区)、结节间区(B区)、斜方嵴区(C区)以及锁骨远端区(D区),再将每个区域分为前半部分和后半部分确定8个亚分区,在亚分区中设置半自动感兴趣区(ROIA1、A2、B1、B2、C1、C2、D1、D2),将每个定量CT扫描图像传输至QCTpro分析工作站,对锁骨远端感兴趣区松质骨骨密度进行测量,测量时注意避开锁骨骨皮质。结果与结论:①不同侧肩部骨密度比较,差异无显著性意义(P>0.05);②锁骨远端A1、A2、B1、B2、C1、C2、D1、D2亚分区骨密度分析,差异有显著性意义(P<0.05),可以认为锁骨远端不同区域骨密度有差别,经过两两比较,除A1与A2,D1与D2,A2与B1之间的骨密度差异无显著性意义(P>0.05),其余亚分区骨密度两两比较差异均有显著性意义(P<0.05);③锥状韧带解剖止点A2区骨密度高于B区,差异有显著性意义(P<0.05);A1区骨密度高于A2区,但差异无显著性意义(P>0.05);斜方韧带解剖止点C1区骨密度高于C2区、D1区及D2区,B区骨密度高于C区及D区,差异有显著性意义(P<0.05);④结果表明,锁骨远端不同区域骨密度存在差异,肩锁关节脱位修复重建时锁骨远端骨密度的区域差异不容忽视,除考虑生物力学因素外,还应考虑将内植物或骨隧道置于骨密度较高的区域,以提高内植物固定强度及稳定性,减少骨隧道扩大、骨溶解、骨折及内植物失效等并发症发生的风险。
