Changes of functional outcome after removal of hook plate fixation of Craig type Ⅱ B distal clavicle fractures

Objective To explore the changes of functional outcome after removal of the hook platefixation of Craig typeⅡB distal clavicle fractures. Methods Thirteen patients who had clavicular hook plate internal fixation for distal clavicle fracture in our hospital from January 2009 to January 2014 were followed up, and their X-ray and shoulder function were evaluated by Constant-Murley score. Results All patients were followed up for (51.77±4.79) months. X-rays showed osteolysis around the hook and signs of traumatic arthritis of the acromioclavicular joint. The Constant-Murley score after removal of the hook plate (88.08±16.32) was significantly higher than before (75.31±9.04) (P< 0.05), with the features of obvious pain relief, normal functional activities and wider range of motion (P< 0.05). But no significant difference was found in muscle strength before and after removal of the hook platefixation (P> 0.05). Conclusion It is important to inform the patients about the necessity of removal of the clavicular hook plates in time as recommended to relieve pain, recover shoulder function and improve life quality effectively.
