［Objective］ To compare the clinical effect of distal clavicular locking plates with that of clavicular hook plates in the treatment of Neer Ⅱ distal clavicular fractures. ［Methods］From September 2014 to August 2017, a total of 46 patients with Neer Ⅱ distal clavicular fractures have undergone surgical treatment in our Department. Said 46 cases were divided into two groups, one group containing 22 cases treated with locking plates, while the other group containing 24 cases treated with clavicular hook plates. Then the two groups were compared in respect of operation time, intraoperative blood loss, length of incision, fracture healing, postoperative pain, postoperative complications and postoperative shoulder joint function, respectively. Pain was evaluated using Visual Analog Scale (VAS), and shoulder joint function was evaluated using Constant-Murley score and UCLA score. ［Results］There was no statistical difference in operation time and intraoperative blood loss between the two groups, the length of incision in the locking plate group was significantly shorter than that in the hook plate group (p < 0.05). Fractures in both groups were healed completely, and there was no significant difference in healing time. Three months after operation, the VAS score, the Constant-Murley score and the UCLA score in the locking plate group were, respectively, significantly better than those in the hook plate group (p < 0.05), which scores, however, showed no significant difference between the two groups six months after operation. Postoperative complications of the locking plate group (2 cases) were significantly lower than those of the hook plate group (9 cases) (p<0.05). ［Conclusion］The treatment of Neer Ⅱ distal clavicular fractures with distal clavicular locking plates resulted in shorter length of incision as compared with clavicular hook plates, which could obviously reduce postoperative short-term pain and postoperative complications. Therefore, locking plates may be considered preferentially in the treatment of Neer Ⅱ distal clavicular fractures.
