  • Effectiveness of anatomical locking plate internal fixation combined with coracoclavicular ligament reconstruction for Neer typeⅡb distal clavicle fractures

    ObjectiveTo investigate the effectiveness of anatomical locking plate internal fixation combined with coracoclavicular ligament reconstruction in treatment of the Neer type Ⅱb distal clavicle fractures by comparing with the simple anatomical locking plate internal fixation.MethodsThe clinical data of 40 patients with Neer type Ⅱb distal clavicle fractures who met the criteria between February 2013 and January 2017 were analyzed. Eighteen cases were treated with anatomical locking plate internal fixation and coracoclavicular ligament reconstruction by using a suture anchor (reconstruction group), and 22 cases were treated only with anatomical locking plate internal fixation (non-reconstruction group). There was no significant difference in gender, age, injured side, causes of injury, associated injuries, time from injury to operation between 2 groups (P>0.05). The operation time, medical expense, postoperative coracoclavicular distance, Constant-Murley scores of injured side, and complications were recorded and compared between 2 groups.ResultsAll patients were followed up 12-27 months (mean, 16.3 months). One patient in reconstruction group had superficial wound infection. One patient in non-reconstruction group had pullout of screws from the distal fragment and reduction loss at 1 month postoperatively. The operation time and medical expense in reconstruction group significantly increased when compared with those in non-reconstruction group (P<0.05). All fractures in 2 groups achieved bony union at last follow-up. The rate of coracoclavicular distance increase of injured side in non-reconstruction group was significantly higher than that in reconstruction group (t=2.371, P=0.023). The Constant-Murley scores at 1 month, 3 months after operation, and last follow-up were significantly improved when compared with preoperative values in 2 groups (P<0.05), but no significant difference was observed between 2 groups (P>0.05).ConclusionBoth anatomical locking plate internal fixation with and without coracoclavicular ligament reconstruction can achieve good effectiveness for the Neer type Ⅱb distal clavicle fractures. Therefore, the coracoclavicular ligament reconstruction is not necessary, except for comminuted fractures with the length of lateral fragment less than 1 cm or the patients with poor compliance.

  • Clavicular hook plate with coracoclavicular ligament augmentation by suture anchor in the treatment of unstable distal clavicle fractures

    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.

  • A meta-analysis of the necessity of coracoclavicular ligament reconstruction in the treatment of unstable distal clavicular fractures with locking plate

    Objective To investigate the necessity of coracoclavicular ligament reconstruction in the treatment of unstable distal clavicular fracture with locking plate. Methods We searched PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang database and VIP database for all the articles about the treatment of unstable distal clavicular fractures using locking plate combined with coracoclavicular ligament reconstruction or locking plate alone from the establishment of databases to November 30th, 2022. According to the inclusion and exclusion criteria, we selected the documents that met the requirements of this paper, and extracted the effective data after evaluating the quality of the documents, including the Constant-Murley score, coracoclavicular distance, fracture healing time, complication rate, operative time, intraoperative blood loss, incision length and the Visual Analogue Scale score of postoperative pain. RevMan 5.4 software was used for meta-analysis. Results A total of 11 retrospective cohort studies were included, and the overall quality of the literature was high. A total of 421 cases were included in this study, including 209 cases in the locking plate combined with coracoclavicular ligament reconstruction group and 212 cases in the locking plate group. The results of meta-analysis showed that locking plate combined with coracoclavicular ligament reconstruction in the treatment of unstable distal clavicular fractures was superior to locking plate alone in the Constant-Murley score [mean difference (MD)=7.35, 95% confidence interval (CI) (2.84, 11.87), P=0.001], coracoclavicular distance [MD=–1.22 mm, 95%CI (–1.92, –0.53) mm, P=0.0006], fracture healing time [MD=–2.76 weeks, 95%CI (–4.74, –0.79) weeks, P=0.006] and complication rate [odds ratio=0.31, 95%CI (0.14, 0.68), P=0.004], but the former had longer operative time [MD=9.27 min, 95%CI (4.53, 14.01) min, P=0.0001]. There was no significant difference in the intraoperative blood loss [MD=3.31 mL, 95%CI (–17.01, 23.63) mL, P=0.75], incision length [MD=0.30 cm, 95%CI (–0.11, 0.71) cm, P=0.15], or Visual Analogue Scale score of postoperative pain [MD=–0.26, 95%CI (–0.79, 0.27), P=0.33]. Conclusions Although the reconstruction of the coracoclavicular ligament increases the time of surgery, locking plate combined with coracoclavicular ligament reconstruction in the treatment of unstable distal clavicular fractures is significantly better than locking plate alone in terms of reduction quality, shoulder function recovery, fracture healing time, and the incidence of complications, without significant intraoperative bleeding, prolonged incision or postoperative pain.

  • Effectiveness of Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor in treatment of Cho type ⅡC distal clavicle fractures

    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.
