Dr. De SmetCan both hips be operated at the same time? In severe osteoarthritis of both (bilateral) hips a bilateral procedure can be done. Both hips are operated on the same day. Our experience today has not given more problems when this is performed in healthy people. A continuous epidural catheter and more blood…

Continue reading →Return to FAQ LIST Dr. Bose:It is a commonly used statement that a BHR is as ‘stable’ as a normal hip. However this is a highly qualified statement. This statement is true only if the following criteria are met: 1. Native angles, inclination , offsets and all anatomical parameters have to be replicated.. If…

For general rehab you could take 6 weeks, 3 months. If patients want to progress harder they can have longer or more frequent physiotherapy, but this would then be more like fitness…

The following is a story about a problem that Dr. De Smet thinks is associated with a metal sensitivity in a BHR. November 08, 2007 Metal…

Our particular interest is in doing the operation exactly right: we plan each operation with a CT scan, which enables us to plan precisely. We then navigate in surgery…

Single injections can relieve pain and swelling and appear to be safe, but repeated injections can damage joints and delay healing. Scientists in Greece injected cortisone-type drugs repeatedly…

This is Dr. Rubinstein’s answer: MRI is perfectly safe with any orthopaedic implant (joint replacements, fracture hardware screws and others). The implants may degrade the picture…

First, wear of implants is a function of how they are used; NOT a function of time! In other words, durability is directly…
Continue reading →Dr. De SmetHow big is the incision of the (hip resurfacing) operation? In a classic total hip replacement the length of incision is between 8 – 15 cm (3-6 inch), depending on the difficulty of the operation (e.g. revision surgery and obesity of the patient). In the resurfacing procedure the incision is longer (15 –…

He wanted to know my opinion and I thought it would…
Continue reading →Return to FAQ LIST Dr. Su For the socket, I believe it takes 3 to 6 months before the bone is fully grown onto the implant. I believe the femoral bone is something that continually remodels, since it is alive. I believe that it is weaker initially after surgery, but strengthens with gradual activity,…

Cup abduction (or Inclination) is a two dimensional assessment. Malposition in the third dimension…

Continue reading →Updated 7/18/08 Dr. BoseThe chronological age is not an absolute criteria. The physiological age, bone marrow density and the anticipated post surgery activity level of the patients are the deciding factors for the suitability of resurfacing procedure. X-rays must be reviewed by the surgeon to assess technical suitability. The youngest patient to undergo this procedure…
Continue reading →Return to FAQ LIST Dr. MacaulayYou 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.

In addition, reduced risk of dislocation, less…

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…
