Objective To summarize the method and effectiveness of open reduction and internal fixation in the treatment of 4 cases of bipolar clavicle dislocations. Methods Between June 2017 and June 2022, 4 patients with bipolar clavicle dislocations were admitted. There were 3 males and 1 female. The age ranged from 27 to 63 years, with an average age of 45 years. There were 2 cases of crushing injury of mine car, 1 case of traffic accident injury, and 1 case of heavy object injury. The time from injury to operation was 3-7 days, with an average of 5.0 days. The sternoclavicular joint dislocations were classified as Grade Ⅱ in 1 case and type Ⅲ in 3 cases, and anterior dislocation in 3 cases and posterior dislocation in 1 case. The acromioclavicular joint dislocations were classified as Tossy type Ⅱ in 2 cases and type Ⅲ in 2 cases. After open reduction, the sternoclavicular joint and acromioclavicular joint were fixed with lateral malleolus locking titanium plate and clavicular hook plate, respectively. ResultsAll operations were successfully completed without vascular or nerve injury. All incisions healed by first intention. All patients were followed up 12-18 months, with an average of 14 months. At last follow-up, the shoulder joint functions were rated as excellent in 3 cases and good in 1 case according to Rockwood score. During follow-up, there was no loosening of internal fixator or fracture. The internal fixators were removed in all patients at 5-7 months after operation (mean, 6 months), and no re-dislocation occurred after removal. Conclusion For bipolar clavicle dislocation, open reduction combined with lateral malleolus locking titanium plate fixation of the sternoclavicular joint and clavicle hook plate fixation of the acromioclavicular joint can achieve good effectiveness. It has the advantages of simple operation, high safety, firm fixation, and fewer complications, and the shoulder function recovers well.
ObjectiveTo investigate and evaluate the effectiveness of the distal radius microplate locking plate for the treatment of displaced fracture of medial clavicle.MethodsBetween January 2013 and June 2017, 18 cases of obvious displaced fracture of medial clavicle were treated with distal radius microlocking plate. There were 10 males and 8 females, with an average age of 51.4 years (range, 18-88 years). Causes of injury included traffic accident injury in 15 cases, heavy object injury in 3 cases; all of them were closed injury. According to Edinburgh classification, 15 cases were ⅠB1 type and 3 cases were ⅠB2 type. Fracture displacement was 12-21 mm (mean, 16.3 mm). The time from injury to operation was 3-7 days (mean, 4.3 days). After operation, the clinical healing and complications of fracture were observed, and shoulder function was evaluated according to Rockwood’s scoring criteria.ResultsNo incisional infection, neurovascular injury, or other early complications occurred. All 18 patients were followed up 8-15 months (mean, 12 months). All fractures reached clinical osseous union, and the healing time was 8-24 weeks (mean, 16.6 weeks). Postoperative plate loosening occurred in 1 case, which was removed surgically, while other patients did not suffer from complications such as bone nonunion, displacement, internal fixator loosening, and loss of reduction. At last follow-up, according to Rockwood’s scoring criteria, the results were excellent in 12 cases and good in 6 cases.ConclusionThe distal radius microplate locking plate is effective for the treatment of displaced medial clavicle fracture, which has few complications, and is feasible for early functional exercise, and is helpful for the recovery of shoulder joint function.
ObjectiveTo evaluate the effectiveness of a clavicular hook plate with coracoclavicular ligament augmentation by suture anchor in the treatment of Neer types Ⅱ and Ⅴ distal clavicle fractures.MethodsBetween January 2010 and June 2016, 16 patients with Neer types Ⅱ and Ⅴ distal clavicle fractures were treated with clavicle hook plates and coracoclavicular ligament augmentation by suture anchor. There were 12 males and 4 females with an average age of 45.6 years (range, 14-81 years). The injury mechanism included falling in 10 cases, traffic accident injury in 2 cases, falling from height in 2 cases, and heavy object injury in 2 cases. The Neer classification of clavicle fractures included 2 cases of type Ⅱa, 13 cases of type Ⅱb, and 1 case of type Ⅴ. The injury severity score (ISS) was 6-29, with an average of 11.2. The time from injury to operation was 1-18 days, with an average of 6.4 days. The operation time, intraoperative blood loss, hospitalization stay, fracture healing, and postoperative complications were recorded; the disability of arm, shoulder, and hand (DASH) score, the shoulder joint Constant score, and the Oxford shoulder score (OSS) were used to evaluate the shoulder joint at last follow-up.ResultsAll operations were successfully completed. The operation time was 50-100 minutes, with an average of 75.6 minutes; intraoperative blood loss was 30-100 mL, with an average of 52.8 mL; hospitalization stay was 4-47 days, with an average of 13.7 days. All patients were followed up 1.2-7.5 years, with an average of 3.5 years. All clavicle fractures healed, and the healing time was 9.4-13.6 weeks, with an average of 11.9 weeks. No fracture nonunion, fracture displacement, failure of internal fixation, or incision infection, etc. occurred. Fifteen patients took out the hook plate after fracture healing and functional recovery, and 1 case refused to remove the hook plate from the second operation because of no obvious discomfort. At last follow-up, the DASH score was 0-13, with an average of 2.2; the shoulder joint Constant score was 90-100, with an average of 96.8; the OSS score was 12-14, with an average of 12.3.ConclusionClavicular hook plate with coracoclavicular ligament augmentation by suture anchor can help achieve good effectiveness with less postoperative complication in the treatment of Neer types Ⅱ and Ⅴ distal clavicular fractures.
Objective To explore effectiveness of minimally invasive internal fixation with locking plates for mid-shaft clavicle fractures. Methods Between October 2022 and August 2023, 28 patients with mid-shaft clavicle fractures were treated by minimally invasive internal fixation with locking plates. There were 10 males and 18 females with a mean age of 46.2 years (range, 18-74 years). The fractures were caused by traffic accident in 16 patients, sports-related injury in 7 patients, and other injuries in 5 patients. According to Robinson classification, the fractures were classified as type 2A1 in 1 case, type 2A2 in 6 cases, type 2B1 in 15 cases, and type 2B2 in 6 cases. The interval between fracture and operation ranged from 5 hours to 21 days (median, 1.0 days). The pain visual analogue scale (VAS) score was 8.1±1.6. The VAS score at 3 days after operation and the occurrence of complications after operation were recorded. During follow-up, X-ray films were re-examined to observe the healing of the fracture; the shoulder joint function was evaluated according to the Constant-Murley score at 6 months, and the length of the incision scar (total length of the distal and proximal incisions) was measured. ResultsAll operations were successfully completed without any subclavian vascular or nerve damage. All incisions healed by first intention. The VAS score was 1.2±0.7 at 3 days after operation, and there was a significant difference in VAS score between pre- and post-operation (t=8.704, P<0.001). At 1 week after operation, the patient’s shoulder was basically painless, and they resumed normal life. All patients were followed up 12-20 months (mean, 13.3 months). X-ray films showed that the bone callus began to form at 2-4 months after operation (mean, 2.7 months). There was no delayed healing or non healing of the fracture, and no loosening or fracture of the internal fixators during follow-up. At 6 months after operation, the mean total incision length was 1.5 cm (range, 1.1-1.8 cm); no patient complained of numbness or paresthesia on subclavicular region or anterior chest wall. The Constant-Murley score of shoulder joint function was 93-100 (mean, 97.6). Conclusion Minimally invasive internal fixation with locking plates is a good surgical method for treating mid-shaft clavicle fractures, with simple operation, minimal trauma, good postoperative results, and high satisfaction.
Objective To evaluate the effectiveness of Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures. Methods The data of 17 patients with Cho type ⅡC distal clavicular fractures, who were treated with Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor between June 2019 and June 2021, was retrospectively analyzed. There were 11 males and 6 females with an average age of 38.7 years (range, 19-72 years). The fractures were caused by falling in 12 cases and traffic accident in 5 cases. All patients had fresh closed fractures. The interval from injury to operation was 1-5 days (mean, 2.6 days). The preoperative injury severity score (ISS) was 6-27 (mean, 10.2). The operation time, intraoperative blood loss, hospital stay, fracture healing, and postoperative complications were analyzed. The shoulder joint function was evaluated by disabilities of the arm, shoulder, and hand (DASH) score and Constant score at last follow-up. Results All operations were completed successfully. The operation time was 20-50 minutes (mean, 31.6 minutes). The intraoperative blood loss was 30-100 mL (mean, 50.6 mL). The hospital stay was 4-9 days (mean, 5.3 days). All incisions healed by first intention. All patients were followed up 12-16 months (mean, 13 months). All clavicle fractures healed, and the healing time was 8-15 weeks (mean, 11 weeks). No complications such as fracture displacement or nonunion caused by internal fixation failure occurred. During the follow-up, skin irritation caused by the Kirschner wire withdrawal occurred in 3 cases. The Kirschner wires were removed after fracture healing in 17 patients. At last follow-up, the Constant score of shoulder joint was 90-100 (mean, 98.2). The DASH score was 0-10 (mean, 1.5). ConclusionKirschner wire fixation combined with coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures has less postoperative complications and slight complications. It is convenient to remove the internal fixator. The Kirschner wire does not fix the distal clavicle fracture through the acromion, which has little effect on shoulder joint function and can obtain good effectiveness.
ObjectiveTo systematically review the safety and efficacy of operative versus non-operative treatment for displaced midshaft clavicle fractures.MethodsDatabases including PubMed, The Cochrane Library, EMbase, MEDLINE(Ovid), CBM, CNKI and WanFang Data were searched to collect randomized controlled trials (RCTs) and cohort studies about operation versus non-operation for displaced midshaft clavicle fractures from inception to June 3rd, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by RevMan 5.2 software.ResultsA total of 14 RCTs and 5 prospective cohort studies involving 1 543 patients were included. The results of meta-analysis showed that operation was superior to non-operation in the Constant score (SMD=0.76, 95%CI 0.40 to 1.13, P<0.000 1), DASH score (SMD=–0.49, 95%CI –0.91 to 0.06,P=0.02), nonunion rate (RR=0.17, 95%CI 0.10 to 0.30, P<0.000 01), malunion (RR=0.20, 95%CI 0.12 to 0.33,P<0.000 01) and patients’ satisfaction rate (RR=1.39, 95%CI 1.13to 1.71,P=0.002), respectively.ConclusionCurrent evidence shows that operation could improve the function of the upper limbs, reduce nonunion and malunion, and improve the satisfaction of the patients with midshaft clavicle fractures. Due to the limited quality of the included studies, more large-scale, high-quality studies are required to verify the above conclusion.
Objective To investigate the effectiveness of arthroscopic distal clavicle resection for the symptomatic acromioclavicular joint arthritis. MethodsThe clinical data of 14 patients with symptomatic acromioclavicular joint arthritis treated by arthroscopic indirect distal clavicle resection between January 2020 and March 2021 were retrospectively analyzed. There were 5 males and 9 females with an average age of 46.3 years (range, 18-57 years). The 4 cases of left shoulder and 10 cases of right shoulder were accompanied with acromial impingement, without the history of shoulder trauma. The average disease duration was 20.4 months (range, 9-48 months), and the average visual analogue scale (VAS) score was 7.6 (range, 5-9) preoperatively. The results were evaluated using the University of California Los Angeles (UCLA) shoulder rating score before and after operation, further, the patient satisfaction rate was also calculated. Results All 14 patients were followed up 5-18 months, with an average of 13 months. There was no postoperative pain of acromioclavicular joint in 12 patients; 1 case had occasional mild pain, which could be controlled by painkillers. Moreover, there was only 1 acromioclavicular joint subluxation due to early fitness training at 2 weeks postoperatively, and the symptoms gradually relieved after 1 month of conservative treatments. The UCLA score was 22.1±6.2 preoperatively, which improved to 30.2±3.4 at last follow-up, showing significant difference (t=5.359, P<0.001). The patient satisfaction rate was 92.9%, with 12 excellent cases, 1 good case, and 1 fair case. Conclusion Arthroscopic distal clavicle resection for symptomatic acromioclavicular arthritis is a safe, reliable, and repeatable procedure.
ObjectiveTo evaluate the technique and effectiveness of dual plates fixation for distal comminuted clavicle fractures. MethodsBetween January 2011 and September 2012, 16 patients with distal comminuted clavicle fractures were treated with dual plates fixation. There were 9 males and 7 females with the mean age of 53.6 years (range, 36-71 years). All the patients had closed fracture, including 10 cases of Craig Ⅱ/type Ⅱ, 5 cases of Craig Ⅱ/type V, and 1 case of Craig Ⅱ/type Ⅱ and Craig Ⅲ, which was caused by traffic accident in 8 cases, by sports in 5 cases, and by falling from height in 3 cases. The average interval from injury to surgery was 48 hours (range, 12-72 hours). The X-ray films were taken during follow-up. The functional recovery of the shoulder joint was assessed using the American Shoulder and Elbow Surgeons (ASES) rating scale score. ResultsAll the patients were followed up 13-17 months (mean, 13.6 months). The X-ray films showed bone union and anatomical reduction in all cases, with the mean time of bone healing of 5.6 months (range, 4-6 months). No complication of implant related fracture, implant failure, malunion, nonunion, or post-traumatic arthritis occurred during follow-up. The mean ASES score was 91 (range, 86-93) at last follow-up. ConclusionDual plates fixation in the treatment of distal comminuted clavicle fractures can obtain a rigid fixation and avoid the interference of acromioclavicular joint and shoulder joint activities, so this technique is a safe and effective method.
Objective To analyze the clinical effect of clavicular hook plate in treating Neer type Ⅱ fracture of distal clavicle. Methods From March 2004 to April 2006, 15 patients suffering from Neer type Ⅱ fracture of distal clavicle were treated with clavicular hook plate, including 12 males and 3 females with an average age of 39 years (range,17-69 years). All patients had acute injury,including accident injury (8 cases) and falling injury (7 cases). The results were assessed by the JOA method. Results The wounds healed by first intention. No early complications were found. All patients were followed up for an average of 16.4 months(range,9-34 months) .The mean JOA score was 93.1. Themean pain parameter was 28.0, the fuction was 18.8 and the range of motionwas 26.3. The X-ray films showed that bony union was obtained in all patients after 3.6 months, and the mean healing period was 3.9 months.No acromioclavicular subluxation and dislocation occurred. Conclusion The principal advantages of this method are reliable fixation and early rehabilitation. It is necessary to protect rotator cuff and tissues behind acromioclavicular joint and remove the plate as soon as possible after bony union.
