Further study details as provided by AO Clinical Investigation and Documentation:

Primary Outcome Measures:
  • - Document specific indications for the surgical treatment of distal radius fractures using the LCP

Secondary Outcome Measures:
  • - Primary reduction and maintenance of reduction of the plate fixation
  • - Functional outcome scoring using "Garetland and Werley, DASH and SF-36 scoring
  • - Patient and surgeon satisfaction
  • - Analysis of the occured complications

Enrollment: 450
Study Start Date: December 2001
Study Completion Date: December 2005
Detailed Description:

In addition the differences between the surgical treatment compared to

conservative treatment with respect to fracture healing, functional outcome

and subject satisfaction will be analysed after 6w./6m./1y./2y.
