The purpose of this study is to determine whether the rate of fracture healing and fracture union, repaired with the LISS device, will be as good as or better than the usual fracture fixation systems.

Further study details as provided by Nova Scotia Health Authority:

Primary Outcome Measures:
  • Delayed union or nonunion of the distal femur [ Time Frame: 12 months post operative ]
    Determined via radiographic analysis

Secondary Outcome Measures:
  • Time to clinical healing [ Time Frame: 12 months ]
    assessed by weight-bearing ability and pain

  • Function as assessed by patient [ Time Frame: 6 months, 12 months ]
    Assessed using LEM, SMFA, and SF-36 questionnaires

  • Frequency of adverse events [ Time Frame: 12 months ]
  • Range of motion [ Time Frame: Post-op, 6 weeks, 3 months, 6 months, 12 months ]
  • Gait analysis [ Time Frame: 12 months ]

Estimated Enrollment: 150
Study Start Date: March 2003
Study Completion Date: July 2009
Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
