Two months after having my hip resurfaced, I needed it replaced. Does this happen often?

Two months after I had my left hip joint resurfaced, I had to have it removed and a total hip done instead. Does this happen very often?

Studies show that complications after hip joint resurfacing range anywhere from zero to four per cent. Other studies support the idea that revisions of this type are caused by errors in surgical technique and patient selection.

For example, joint resurfacing is not advised in older, postmenopausal women. The bone is often osteopenic or osteoporotic (decreased mass) and may fracture at the femoral neck. Obesity is also a negative risk factor. Anyone with a BMI more than 35 is not a good candidate for this type of surgery.

Surgeons must be trained and experienced in using this technique in order to reduce the risk of fracture and other complications. Implant loosening, hip dislocation, and infection are the other most likely complications from this new procedure.

Other ways to avoid femoral neck fractures have been suggested. The implant must be positioned carefully. Any malalignment or imbalance can contribute to problems. Weak bone may not be able to support the implant with fracture as the result.

Most often complications are the result of several (if not many) factors combined together. The rate of complications declines with each surgeon with practice and experience. Patients with severe arthritic changes are usually treated with a total joint replacement, bypassing this step altogether.

Obesity a factor in total hip replacement surgery

I have been overweight all my life and now my hips are so bad with arthritis I need replacements. The doctor has told me to lose weight, but how much is enough?

A recent report on 851 cases of total hip replacement included information on patient demographics. This refers to data about the patients’ ages, gender, diagnosis, and body mass index (BMI).

BMI is calculated based on height and weight. It helps show how much body fat you have. Health risks from carrying too much weight include heart disease, diabetes, and arthritis.

A BMI in the “healthy” range does not always mean the person is fit and healthy. Poor diet and genetics can put an average person at risk for health concerns. Keep in mind the BMI does not take into account body frame. A muscular, large-framed person’s BMI could indicate obesity, but this may not be the case.

The Centers for Disease Control and Prevention (CDC) offer a website with easy calculations of your BMI. You can do this by going to:

Once you’ve found your BMI ask your doctor about a reasonable weight loss plan. Studies show results after a hip replacement are best in patients with a BMI of 30 or less.
