Birmingham Mid Head Resection
Birmingham mid head resection is an alternative procedure for those people
who do not qualify for Hip Resurfacing. For example, people having serious
femoral head deformity or inadequate bone quality, are not suitable for a
BHR. Rather than opting for a total hip replacement, patients in this
condition have another bone conserving alternative which is the Birmingham
Mid Head Resection. Apart from conserving the bone of the patient, those
who successfully undertook the BMHR surgery will return to an active
lifestyle.
3. During the BMHR operation, the upper portion of the femoral head is
opened, and any region of diseased or necrotic bone is removed. Then
a conical cavity is cut, and the stem is tapped into place
4. The stem is then fitted with a large diameter modular head. It matches the patients’ own
anatomy closely. The same acetabular cup which is used for a BHR is used for fitting the
femoral head component.

Scientific tests have shown that the
physiological loading of the native femur is
replicated by the conical design of the stem,
and this prevents stress shielding bone loss in
the long term. The BMHR is developed after
the success of the BHR. It gives the same
advantages of the Hip Resurfacing. The
advantages are natural movements without
dislocation and you will be able to return to
your active lifestyle.

The line of resection of the femoral head is
through the middle portion of the femoral head.
This ensures the removal of the poor quality bone
from the top half of the femoral head, and the
lower part of the femoral head is retained. The
lower part of the femoral head contributes to load
transfer from the stem. The effect of load bearing
through this upper region of the femur prevents
the stress shielding deterioration of the neck. This
has been noticed in other neck preserving hip
replacements. The benefit of this procedure is that
it gives you the option of converting to a total hip
replacement in the future if the need arises.

The design of BMHR started in the early 2002.
It was based on sound anatomical and
biomechanical considerations. BMHR makes
use of the same socket and the same bearing
as a BHR. The wear performance too is similar
to BHR. The main problem with BMHR was
whether the stem design can favor long lasting
stability and robust fixation, and whether the
implant bone load transmission will provide
safe and effective loads to allow the bone to
withstand it in the initial phase.
