Operative Technique
10. Cylindrical Reaming - Femoral Head
Prior to commencing cylindrical reaming, it is
important to understand the correlation between
the ReCap
®
femoral and acetabular components.
When standard acetabular components are used,
there is a 6mm difference between the femoral
and acetabular components (see chart page 6). For
example, a 50mm ReCap
®
resurfacing component
FLV HERE
is designed to articulate within a 56mm diameter
ReCap
®
acetabular component. ReCap
®
acetabular
components require the acetabulum to be reamed
either 1mm or 2mm smaller than the component,
depending on the bone quality.
It is, therefore, recommended that the first
Figure 17
cylindrical reamer used is at least one size larger
than that selected at the femoral head/sizing stage
of the operation. This provides the option to up size
the femoral component to match that of a stable
acetabular component, or remove bone from the
femoral head, in order to ream the femoral head to
the size of acetabular component originally selected.
Once the appropriately sized cylindrical reamer
has been selected, it is placed over the guide rod
and advanced, taking care not to notch the femoral
neck. The cylindrical reamer will stop cutting when it
reaches the guide rod stop. With a STD guide rod in
place, the cutting teeth of the cylindrical reamer will
extend 5mm beyond the outer edge of the implants
articulating surface. (Figure 17)
Should the femoral neck become notched during
reaming, the resurfacing procedure should
immediately change to a total hip procedure.
(See stage 17)
11. Acetabular Preparation and Implant
Insertion
Prior to spherical reaming of the femoral head, it
is recommended to prepare the acetabulum and
implant the acetabular component. This provides
the option to up size the acetabular component
to achieve stable fixation, or implant the size of
component originally selected during the pre-
operative planning or sizing of the femoral head/
neck.
