To investigate the effectiveness of T-locking plate in treating medial clavicle fracture so as to find out a therapy with safety and stabil ity. Methods Between October 2006 and January 2009, 13 patients with medial clavicle fracture were treated with open reduction and T-locking plate fixation. There were 9 males and 4 females, aged 18-68 years (mean, 47 years), including 7 cases of traffic accident injury, 4 cases of fall ing injury from height, and 2 cases of heavy object hit injury. The locations were left side in 5 cases and right side in 8 cases. All cases were closed fracture. The disease duration was 1 hour to 14 days. Results All incisions healed by first intention after operation. The X-ray films showed good reduction of fracture and internal fixation. All the 13 patients were followed up 12-18 months (mean, 15 months). The average fracture heal ing duration was 8 weeks (range, 6-12 weeks). No compl ication of infection, nerve or blood vessel injury, hemopneumothorax, or internal fixation loosening or failure occurred. The anatomical medial clavicle structure as well asappearances and functions were restored. According to Rockwood’s score method, the results were excellent in 11 cases and good in 2 cases. Conclusion The internal fixation of T-locking plate in treating medial clavicle fracture has the advantages of good stabil ity and low risk. Besides, the patients can do functional exercises early and the shoulder joint function can be improved in great degree.
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.

Objective To investigate the cl inical efficacy, compl ications and necessity of removing internal fixation in treatment of fresh Tossy type III acromioclavicular joint dislocations and Neer type II distal clavicle fractures with clavicularhook plate. Methods From June 2005 to June 2008, 24 patients with fresh Tossy type III acromioclavicular joint dislocations and 20 patients with fresh Neer type II distal clavicle fractures were treated. There were 32 males and 12 females with an agerange of 18-66 years (38.5 years on average), involving 18 left shoulders and 26 right shoulders. The injury was caused bytraffic accident in 31 cases and by fall ing in 13 cases. The mean time from injury to operation was 4 days (range, 2-8 days). All patients were treated by reduction with clavicular hook plate fixation. The coracoclavicular l igaments were not sutured. The shoulder functions were evaluated according to University of Cal ifornia-Los Angeles (UCLA) score system and analysed before and after removing internal fixation. Results Wound infection occurred in 2 cases 1 week after operation and healed after symptomatic managment, the other incisions healed by first intention. One case accepted hook plate fixation again because of loosening hooking-up 1 week after operation. One case accepted hook plate removal and Kirschner wire fixation because of severe shoulder’s pain on the postoperative third day. Thirty-eight patients were followed up for 8-32 months (18 months on average), there was no plate breakage. Clavicle fractures got bony union after 3-6 months (4.2 months on average). At last followup (before plate removal), according to UCLA shoulder function score system, the results were excellent in 11 cases, good in 22 cases, and fair in 5 cases; the excellent and good rate was 86.8%. Because of shoulder’s pain, plates were removed in 20 patients 3-16 months (10 months on average) after operation. The cases were followed up 3-8 months (5 months on average) after removing plate. No dislocation and fracture occurred again. There was statistically significant difference (P lt; 0.01) in the functional scores of shoulder between before (30.55 ± 4.00) and after removing internal fixation (33.85 ± 1.95). Conclusion Clavicular hook plate fixation is an effective treatment for fresh Tossy type III acromioclavicular joint dislocations and Neer type II distal claviclefractures. Normative operating, correct plate moulding, functional rehabil itation after operation are key factors in preventingcompl ications and reaching good cl inical efficacy. For the patients with postoperative symptoms, the plate should be removed to improve the shoulder’s function.
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.
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.
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.
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 investigate the effectiveness of double internal fixations of clavicle and scapula and intraoperative reduction of glenopolar angle in the treatment of floating shoulder injuries.MethodsBetween January 2010 and June 2019, 13 patients with floating shoulder injury were treated with double internal fixation of clavicle and scapula and intraoperative reduction of glenopolar angle. There were 11 males and 2 females with an average age of 48 years (range, 25-65 years). The causes of injury included falling from height in 2 cases, traffic accident injury in 3 cases, heavy object injury in 2 cases, and other injuries in 6 cases. There were 2 cases of Ⅰ-B-3 type, 1 case of Ⅰ-C-2 type, 1 case of Ⅰ-C-3 type, 3 cases of Ⅱ-B-2 type, 1 case of Ⅱ-B-3 type, 1 case of Ⅱ-B-4 type, 2 cases of Ⅱ-C-2 type, 1 case of Ⅱ-C-4 type, and 1 case of Ⅱ-D-3 type according to the classification of floating shoulder injury. All patients had unilateral clavicle fracture with scapular neck fracture, 1-4 superior shoulder suspensory complex (SSSC) injuries. The time from injury to operation was 7-17 days, with an average of 12 days. The glenopolar angle, subacromail space, anteroposterior inclination angle of scapular glenoid, scapular glenoid up and down angle were measured before and after operation; Constant-Murly score and Herscovici score were used to evaluate the recovery of shoulder joint function.ResultsAll incisions healed by first intention, and there was no early postoperative complications such as infection. All 13 cases were followed up 12-48 months, with an average of 25.2 months. Both the clavicle and the scapula had bone union, and the average healing time was 6 months and 4 months respectively. There were no complications such as nonunion, shoulder deformity, plate fracture or failure of internal fixation, acromion impingement syndrome, and frozen shoulder. At last follow-up, the glenopolar angle, subacromail space, anteroposterior inclination angle of scapular glenoid, and scapular glenoid up and down angle were all corrected significantly (P<0.05). The pain, function, activity, muscle strength scores, and total score in Constant-Murly score were significantly improved when compared with preoperative scores (P<0.05). According to the Herscovici scoring standard, the shoulder joint function was evaluated as excellent in 8 cases, good in 3 cases, and fair in 2 cases. The excellent and good rate was 84.6%.ConclusionDouble internal fixation of clavicle and scapula to stabilize SSSC and reduct glenopolar angle during operation is an effective method for treating the floating shoulder injury.
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.
