Dr. Macaulay You may feel some numbness in the skin around your incision. You also may feel some stiffness, particularly with excessive bending. These differences often diminish with time and most patients find these are minor compared to the pain and limited function they experienced prior to surgery.
Theoretic advantages are less bone destruction,
less bone resection, normal femoral loading, avoidance of stress
shielding, maximum proprioceptive
feedback, and restoration of normal anatomy. In addition,
reduced risk of dislocation, less leg inequality problems, and
easier revision should convince surgeons to favor metal-on-metal
A resurfacing is suitable for the treatment
of a hip with severe arthritis when the femoral head bone
quality is good.
The ball (femoral) and socket (acetabular) components of a BHR
are made of a tried and tested alloy of cobalt and chromium.
This has been in use in orthopaedic surgery for over 70 years.
The original alloy is an as-cast high-carbon alloy. The higher
carbon content precipitates in the alloy as carbides which have
the hardness of ceramics. They give the metal the needed
We use whole blood specimens drawn into
lithium-heparin containing tubes with
non-contamination precautions, and analysed with
HRICPMS (high resolution inductively coupled
plasma mass spectrometry) for the most accurate
assessment of metal ion levels.
The problem with using serum, plasma or
erythrocytes is that metal ions are
differentially distributed in the intracellular
and extracellular compartments and introduces
variability. Furthermore the specimen must be
centrifuged and separated locally soon after
Mr. McMinnIf someone is allergic to
certain metal jewellery, what are the chances of
having a deep tissue allergy? What is the most
accurate way of testing someone for a deep
tissue allergy? It is estimated that approximately 10% of the
population shows skin (cutaneous) allergy to
metal products like costume jewellery. In terms
of deep tissue allergy the leading authorities
agree that, ‘clinically important metal

Dr. SuI still use the BHR, Conserve Plus, and Biomet Recap. I think
the devices are very similar, but the BHR has the longest track
record, which is very important to me. The other devices do have
the benefit of more sizes than the BHR for right now (at least
in the US), so there are some patients for whom they fit better.
What metal ion levels are considered high and to be of concern for a patient to seek out treatment by Mr. McMinn
People report being told by their surgeons that they have “elevated levels of cobalt” ranging from single digit numbers (one person reported 9.2 for example) up to numbers as large as 2400+. What is the point at which one should have serious concern? If one person is living … Read the rest
Dr. PispatiYou are correct. AVN has 4
stages – 1 and 2 are the early stages.
Stage 3 and 4 are the stages of arthritis –
these last 2 stages are diagnosable on x rays.
Stages 3 and 4 can be treated with resurfacing.
Dr. RubinsteinFrom my point of view as a resurfacing
doc there is likely little to
be gained from an mri at this point. If
Anterior Vs Posterior Incisions & Incision Length by Dr. Ethan Lichtblau, Montreal, Quebec & Dr. De Smet of Belgium
Dr. De Smet of Belgium
Does the length of incision influence the rehabilitation?
No! A bigger incision does not mean that there will be more
damage to the muscular structures. On the contrary, if you
need a bigger incision to get better exposure, the placement
of the implant can be done
Dr. Su Femur fracture
Because the bone of the femur is retained, it is possible to fracture it after surface replacement. Most of the fractures occur early in the post-operative period if too much weight is put on the leg too early. The body needs time to adapt to the new prosthesis. Post-operatively, crutches are used for 3-4 weeks to protect the amount of weight put on the leg. With
