Abstract
An instrument () for use in measuring blood flow in the femoral head after a femoral neck fracture comprises a sleeve () and a rod () which is displaceably mounted in the sleeve. The sleeve () is configured for insertion into a bore () in the femoral neck () and femoral head () and provided with at least one aperture () at a front portion () thereof. The aperture () in the front portion () of the sleeve () is intended for location in the femoral head () distally of the fracture () after the sleeve has been inserted into said bore (). The rod () is configured for closing the aperture () in the sleeve () during insertion of the sleeve into the bore () in the femoral neck () and femoral head () and for exposing said aperture after said insertion. Thereby, blood leaking into the bore () at the front portion () of the sleeve () can be collected by the sleeve through the aperture () therein for subsequent measuring of the volume of the collected blood.
