Femoral Head Sphericity Gauge
The femoral head sphericity gauges manufactured by Corin assist in femoro-acetabular impingement (FAI) surgery by providing a guide as to the amount of femoral head to be resected to prevent cam impingement. 
Cam impingement is a common type of FAI which has recently been recognised as a cause of early osteoarthritis(1). It is treated by debriding the non spherical part of the femoral head which impinges on the labrum.
The gauges are available from 40-56mm in 2mm increments.
