Operative Technique
3. Surgical exposure
The ReCap
®
Hip Resurfacing System can be
implanted using any of the standard approaches
for total hip replacement. The aim of the approach
selected is to provide adequate visualisation of
both the acetabulum and proximal femur. However, FLV HERE
the selected method of guide pin positioning will
ultimately determine the size of incision necessary.
The incision length when utilising the alignment
frame and laterally positioned pin tends to be
greater than the incision required when utilising the
ReCap
®
KS Alignment Device. (Figure 1)

4. Femoral Head/Neck Sizing
Once the soft tissues have been resected and the
femoral head dislocated, it is important to perform
an intra-operative check to confirm the size of
femoral head selected at the pre-operative planning
stage is correct. This is achieved by placing the
closed end of the head/neck-sizing gauge over the
femoral head and the open end over the femoral
neck. The closed end of the head/neck sizing gauge
equates to the outside diameter of the femoral
resurfacing component, whilst the open end equates
to the internal diameter of the femoral resurfacing
Figure 2
component. (Figure 2)
This is important as it confirms that an appropriate
size implant has been selected and determines
whether notching of the femoral neck will occur
during cylindrical reaming. Once the diameter of the
femoral head has been verified, the size is recorded
on the ReCap
®
white board provided. (Figure 3)
