Study summary

This is a Randomized Controlled Trial study comparing hemialloplastik versus total joint replacement.

Read the detailed description

Seventy patients over seventy years who are admitted in our hip fracture department with the indication for hemi joint replacement therapy, due to a Garden 3-4 femoral neck fracture or a fracture Garden 1-2 with over 20-degree posterior tilt are randomized to either hemialloplastik or total joint replacement. The patients are followed for 24 mouths with X-ray Stereo Photogrammetric Analysis (RSA) radiographs and clinical examinations.

What researchers measure

Primary outcomes

  1. Radiographic and clinical

    Migration / rotation: Migration is measured by X-ray Stereo Photogrammetric Analysis (RSA). Clinical assessment: The patient is assessed clinically using the WOMAC and EQ-5D.

    Time frame: Five years

Secondary outcomes

  1. Clinical

    Implant Placement: Mobilisation: Patient mobilization level before the fracture is assessed by the New Mobility Score.Under hospital assessed patients' ability to time with current time instrument daily using the Cumulated ambulation score (CAS). Bleeding: Perioperative bleeding set in operation description from start to suture the incision closed. Hgb is measured as standard on the third day in all patients in the hip fracture unit. In addition, registered the need for blood transfusions in the first four postoperative days.

    Time frame: Five years
