Objective To evaluate the early clinical effect of a new type of titanium plate combined with titanium cable fixation in the treatment of acromioclavicular joint dislocation.
Methods The clinical data were reviewed in 10 patients with acromioclavicular joint dislocation of Rockwood Type Ⅲ, and were treated by a new type of titanium plate combined with titanium cable fixation. Preoperative and postoperative coracoclavicular distance and acromioclavicular joint space were compared by imaging examination, and the loss of reduction was observed at 1 month, 3 and 6 months after operation were observed. Six months after the operation, the shoulder joint efficacy was evaluated according to the Karlsson evaluation standard of shoulder joint. The Visual Analogue Scale (VAS) and Constant-Murley shoulder joint function score were used to evaluate the shoulder joint function of the patients before operation, 3 and 6 months after operation.
Results All patients were followed up. Karlsson standard was used for evaluation at 6 months after surgery, the results showed that there were 8 excellent cases, 2 good cases. The preoperative coracoclavicular distance and acromioclavicular joint space significant difference compared with 1 month after operation (P < 0.05). There were no significant differences between the coracoclavicular distance and the acromioclavicular joint space at 1 month, 3 and 6 months after operation (P > 0.05). The VAS scores and Constant-Murley shoulder function scores before operation showed significant differences compared with those at 3 and 6 postoperative months (P < 0.05).
Conclusion The new steel plate fixation combined with titanium cable fixation can effectively treat Rockwood Ⅲ type acromioclavicular joint dislocation, has less interference to the acromion and shoulder joint, and is simple in operation and firm in fixation, which guides a new direction for the treatment of acromioclavicular joint dislocation.
