Abstract:

BACKGROUND: Clavicular hook plate fixation is a extensively used method in repair of acromioclavicular dislocation in recent years. The metal hook of the clavicular hook plate occupied subacromial space. Some patients affected joint pain. Therefore, it is necessary to find a better fixation material to replace clavicular hook plate.
OBJECTIVE: To explore the curative effect of threaded rivets versus clavicular hook plate in treatment of the Tossy III acromioclavicular joint dislocation.
METHODS: We retrospectively analyzed clinical data of 51 cases of type Tossy III acromioclavicular joint dislocation. All follow-up data were obtained including 27 cases in the clavicular hook plate fixation group and 24 cases in the threaded rivets group. Imaging results, clinical therapeutic effects and complications were compared and analyzed after fixation in both groups.
RESULTS AND CONCLUSION: No significant difference in Japanese Orthopaedic Association scores was detected between the clavicular hook plate fixation group and threaded rivets group (P > 0.05). At 3 months after fixation, the incidences of subacromial impingement syndrome and acromial bone erosion were higher in the clavicular hook plate fixation group compared with the threaded rivets group, and the visual analogous scale scores were significantly higher than the threaded rivets group (P < 0.05). Results suggested that both two methods can be used to treat type Tossy III acromioclavicular joint dislocation, with similar clinical curative effects, but the threaded rivets have the advantage of preventing the postoperative complications such as acromial bone impact and erosion, subacromial impingement and lysis.
