Outcome Measures

Primary Outcomes (1)

  • Percent of Patients in Which Bone Union Has Been Achieved

    The clinical benefit of CHIMAERATM will be assessed by the percentage of patients in which bone union has been achieved within 12 months from the nail implant.

    12 months

Secondary Outcomes (1)

  • Percent of Patients That Required a Reoperation

    6 months

Study Arms (1)

patients with femur fractures

adult patients with pertrochanteric, intertrochanteric and subtrochanteric fractures of the femur

Device: Chimaera Long Nail

Interventions

The CHIMAERATM, is an internal fixation system intended intended for insertion into the medullary canal of a femur in individuals suffering from stable and unstable pertrochanteric, intertrochanteric and subtrochanteric fractures of the femur alone or when these fractures occur in combination with shaft fractures extending distally to a point approximately 10cm proximal to the intercondylar notch.

  • Patient has been diagnosed with bilateral proximal femur fractures.
  • Patient who needed the application of, or ha already in-situ a concomitant not permitted device which cannot be safely removed.
  • Patient with other concurrent medical or non-medical condition that in the opinion of the participating investigator may prevent participation or otherwise render the patient ineligible for the study.
