title: Superior clavicle plate with lateral extension for displaced lateral clavicle fractures: a prospective study.
abstract: BACKGROUND
  Until now there have been no prospective studies describing the results of using the superior clavicle plate with lateral extension in patients with displaced lateral clavicle fractures (Neer type 2). The purpose of this study was to evaluate the results of applying this plate for this specific type of fracture.
  
  
  METHODS
  In this prospective study, seven patients (mean age 43, M:F; 6:1) with a fresh displaced lateral clavicle fracture were evaluated with a mean follow-up of 10 months. Analysis included functional and subjective outcome, time until union, time until return to work, and complications.
  
  
  RESULTS
  All patients achieved clinical and radiological union within 6-12 weeks. Full range of motion as well as a return to work was achieved in most cases within 2 weeks. The mean Constant score was 98 (range 90-100), the DASH score was 3.6 (range 0-11.4), and the Shoulder Rating Questionnaire score was 97 (range 96-100). No major complications were encountered. Three patients required plate removal: two because of a prominent and subcutaneous plate and one because of an intra-articular screw.
  
  
  CONCLUSIONS
  In this study, use of the superior clavicle plate with lateral extension yielded excellent results in the treatment of this difficult fracture. In particular, patients acquired full range of motion within 2 weeks, reflecting the stability of the osteosynthesis achieved with this implant.
