Effects of anatomical plates and clavicular hook plates for treatment of distal clavicular fractures / 中华创伤杂志

ABSTRACT

Objective To compare the clinical results of distal clavicular anatomical plates and clavicular hook plates in treatment of distal clavicular fractures.Methods Twenty-six patients with lateral 1/3 clavicular fractures of Craig Ⅱ type Ⅱ or Ⅴ treated from August 2009 to January 2011 were enrolled in the study.Eleven patients were managed by anatomic plates,including eight patients with type Ⅱ fractures and three with type Ⅴ fractures,while the rest 15 patients were treated by clavicular hook plates,including 11 patients with type Ⅱ fractures and four with type Ⅴ fractures.General information of the two groups was comparable before operation.Shoulder function after operation was evaluated by Constant-Murley score system.Postoperative radiographic findings and complications of patients in the two groups were studied comparatively.Results The distal clavicular anatomical plate group presented a lower incidence of shoulder pain and better mobility of shoulder,as compared with the clavicular hook plate group,but there were no significant differences in incision infection and implant loosening between the two groups.According to the Constant-Murley evaluation standard,excellence rates of the distal clavicular anatomical plate group and clavicular hook plate group were 91％ and 73％,respectively.Conclusion The distal clavicular anatomical plate is conducive to decrease of incidences of shoulder pain,increase of range of motion of shoulder and reduction of complications for treatment of Craig Ⅱ type Ⅱ or Ⅴ distal clavicular fractures and hence is in favor of early functional recovery of the limbs.
