Objective To 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.Methods Between 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.Results All 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.Conclusion Clavicular 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.
