目的 比较克氏针张力带与锁骨钩钢板治疗RockwoodⅢ型肩锁关节脱位的临床疗效。 方法 1999年1月－2007年3月，收治肩锁关节脱位患者29例，分别采用克氏针张力带联合喙锁韧带重建（克氏针组10例）和锁骨钩钢板（钢板组19例）治疗。其中男18例，女11例；年龄19～50岁，平均38.2岁。患者均为新鲜RockwoodⅢ型肩锁关节脱位，受伤至手术时间1～16 d，平均3 d。两组患者性别、年龄、受伤至手术时间等一般资料比较差异无统计学意义（P＞0.05）。进行两组患者术后临床及影像学评估比较。 结果 25例患者（克氏针组10例，钢板组15例）获随访，随访时间2～12年，平均6年。术后克氏针组发生克氏针弯曲5例、断裂1例；钢板组切口浅表感染2例，经换药后治愈，其余患者切口Ⅰ期愈合。两组患者肩锁关节均获得良好功能，组间比较差异无统计学意义（P＞0.05）。影像学方面：与克氏针组相比，在患肢负重位时钢板组喙锁间隙间距增加了23%（P＜0.05），非负重位两组间距差异无统计学意义（P＞0.05）。术后8～12周出现喙锁韧带钙化，钢板组12例、克氏针组2例（P＜0.05）。术后6个月出现肩锁关节骨性关节炎，钢板组2例、克氏针组1例（P＞0.05）。肩关节功能与影像学结果无相关性（r=0.096，P＞0.05）。 结论 克氏针张力带联合喙锁韧带重建和锁骨钩钢板固定治疗RockwoodⅢ型肩锁关节脱位均可获得良好的临床功能。与克氏针张力带相比，锁骨钩钢板固定具有手术操作简便、疗效确切、并发症少、能够早期康复锻炼等优点。
To explore the operative method and the cl inical outcomes of repairing acromioclavicular dislocation by clavicular hook plate internal fixation and coracoacromial l igament transposition. Methods From August 2004 to December 2007, 12 cases of acromioclavicular dislocation were repaired with the internal fixation of clavicular hook plate and the transposition of coracoacromial l igament. There were 9 males and 3 females aged 22-56 years old (average 32 yearsold). Causes of injury: 6 cases from fall ing injury, 4 cases from crush injury and 2 cases from traffic accident. There were 5 cases of the left acromioclavicular dislocation, and 7 cases of the right. According to acromioclavicular dislocation classification set by WANG Yicong, 8 cases were graded as type III, 3 cases as type IV, and 1 case as type V. The time from injury to operation was 3-28 days (average 6 days). The injured arm was hung after operation, and the function training was started 3-5 days after operation. Results All wounds healed by first intention, and the X-ray films showed complete reposition of acromioclavicular joints was achieved in all cases 1 week after operation. Over the follow-up period of 12-30 months, no plate and screw loosening, hook break and acromion fracture occurred. At 2 months after operation, 2 patients had sl ight pain when moving the shoulder, and the symptom disappeared when removing the plate. No re-dislocation was observed in all cases after removing the plate at 6-10 months after operation. The function of shoulder joint was assessed by Karlsson evaluation standard 1 year after operation, 11 cases were graded as excellent and 1 case was good. Conclusion For the repair of acromioclavicular dislocation, the method of combining clavicular hook plate internal fixation with coracoacromial l igament transposition has the advantages of minor wound, easy operation, l ittle influence on the function of shoulder joints, and rel iable restoration of the stabil ity of shoulder joint.
【Abstract】 Objective To evaluate the early result of tri ple Endobutton technique for reconstructing coracoclavicularligament of chronic complete acromioclavicular joint dislocations. Methods Between January 2009 and June 2010, 14 patients with chronic complete acromioclavicular joint dislocations were treated with tri ple Endobutton technique for reconstructing coracoclavicular ligament. There were 10 males and 4 females with a mean age of 38.5 years (range,26-52 years). Injury was caused by traffic accident in 7 cases,by falling in 5 cases，and by bruise in 2 cases. The average time was 47 days from injury to the operation (range,29-75 days). All patients had pain and activity restriction. The X-ray films showed complete dislocation of acromioclavicular joint. According to Allman’s type, all cases were classified as III degree complete dislocations. Results At postoperation, wound healed by first intention with no early complication of infection or neurovascular injury. All patients were followed up 18.3 months on average (range,13-30 months). Acromioclavicular joint subluxation occurred in 1 patient at 1 week after operation, and no redislocation or other complication occurred in the other patients. American Shoulder and Elbow Surgeons (ASES) score was 90.8 ± 4.1 at last follow-up, showing significant difference when compared with the preoperative score (65.3 ± 4.4) (t= —17.57，P=0.00); Constant-Murley score was 91.7 ± 3.9, showing significant difference when compared with preoperative one (71.5 ± 4.6) (t=—75.02，P=0.00). The definite answer in Simple Shoulder Test (SST) averaged 9.7 (range,7-12). Conclusion The tri ple Endobutton technique for reconstructing coracoclavicular ligament is an effective method in treatment of chronic complete acromioclavicular joint dislocations. The short-term results are satisfactory.
ObjectiveTo compare the effectiveness of triple Endobuttons and clavicular hook plate fixation in the treatment of fresh acromioclavicular joint dislocation (Rockwood type III-V). MethodsBetween February 2008 and October 2010, 40 patients with fresh acromioclavicular joint dislocation (Rockwood type III-V) were treated with triple Endobuttons in 18 cases (trial group) and with clavicular hook plate in 22 cases (control group). There was no significant difference in gender, age, disease duration, joint dislocation classification, preoperative visual analogue scale (VAS) score and Constant-Murley score between 2 groups (P gt; 0.05). ResultsAfter operation, wound healed by first intention with no early complication of infection or neurovascular injury. The patients were followed up 12-20 months (mean, 15.8 months) in trial group and 13-24 months (mean, 17.2 months) in control group. Significant differences were found in the VAS score and Constant-Murley score at the last follow-up between 2 groups (P lt; 0.05). X-ray films showed no loosening of internal fixators or hook displacement occurred. No re-dislocation was observed. ConclusionTriple Endobuttons has less shoulder pain and better shoulder motion than clavicular hook plate, so it is an effective method of treating Rockwood type III-V fresh acromioclavicular joint dislocation.
ObjectiveTo investigate the short-term effectiveness of arthroscopic assisted double Endobutton “8” buckle fixation in the treatment of Rockwood Ⅲ type acute acromioclavicular joint dislocation.MethodsThe clinical data of 12 patients with Rockwood Ⅲ type acute acromioclavicular joint dislocation who were treated with arthroscopic assisted double Endobutton “8” buckle fixation between June 2016 and June 2019 were analyzed retrospectively. There were 8 males and 4 females, with an average age of 47.0 years (range, 36-58 years). There were 4 cases of left shoulder and 8 cases of right shoulder. The causes of injury included traffic accident injury in 7 cases and falling injury in 5 cases. The average time from injury to operation was 5.0 days (range, 3-14 days). Before operation and at last follow-up, the shoulder joint activity was recorded; the improvements of function and pain were evaluated by Constant score and visual analogue scale (VAS) score, respectively; the reduction was evaluated by measuring the coracoid spacing of the affected side on the anteroposterior X-ray film of shoulder joint.ResultsAll 12 cases were followed up 6-36 months, with an average of 20.6 months. All the incisions healed by first intention. There was no complications such as clavicle and coracoid fractures and Endobuton displacement. At last follow-up, the range of motion of the abduction improved from preoperative (77.5±4.5)° to (162.5±6.5)°, the range of motion of forward flexion improved from (84.1±5.2)° to (169.5±5.8)°, the Constant score improved from 42.5±2.3 to 92.4±2.3, the VAS score improved from 5.4±0.8 to 0.6±0.5, and the coracoid spacing reduced from (20.5±1.4) mm to (9.2±0.6) mm, all showing significant differences (P<0.05).ConclusionArthroscopic assisted double Endobutton “8” buckle fixation for the treatment of Rockwood Ⅲ type acute acromioclavicular joint dislocation is safe, less invasive, and quicker recovery. It can effectively alleviate shoulder pain, significantly improve the mobility of the shoulder joint, and achieve good short-term effectiveness.
