Brief Summary:

This project investigates wether the intra-capsular hematoma, that often occurs after fracture of the femural neck, decreases the capillary blood flow of the caput femoris.

During operation the measuring device of the O2c-machine in placed on the joint capsula first and afterwards, after surgical opening of the capsula, on the femur directly. The integral of the microcirculation of both parts of the femur is measured in both settings. So the capillary blood flow is measured with the hematoma still in situ, eventually putting pressure on the caput femoris and after the capsula has been opened, the pressure relieved and the hematoma removed. Both measurements are compared for each patient.

The O2c-machine measures non-invasive with light waves and laser-doppler. The sounding rod is packed in a sterile tube to prevent any contamination of the operation site.

Group/Cohort Intervention/treatment
Patient with fracture of femural neck
All patient with fracture of the femural neck in the listed period of time
Procedure: Measurement with O2c
Intra-surgery measurement of the microcirculation with the O2c device

Primary Outcome Measures :
  1. Microcirculation of the caput femoris befor the capsula of the joint is opend

    Four Values are measured:

    oxygen saturation local Hb local blood flow local blood velocity

Secondary Outcome Measures :
  1. Microcirculaiton of the caput femoris after the capusla of the joint has been surgically opened and the hematoma has been removed

    Four values are measured:

    oxygen saturation local Hb local blood flow local blood velocity
