Abnormal bone may form in the tissues adjacent to the joint as a reaction to surgery. Some patients are more prone to this. This does not cause pain. If it is extensive, it may decrease motion. Most patients with an arthritic hip have loss of motion. After resurfacing the hip returns to near normal motion after 1 year of healing. Exceptions are case with certain deformities, extreme stiffness before surgery, and in rare cases where extensive heterotopic bone forms.

We try to prevent this by the following measures:

• Protective covers over muscle during surgery when bone is reamed.
• Thorough jet lavage of hip prior to closing.
• 2 week course of celebrex or Mobic
• Single doe of x-ray therapy after surgery in high risk patients.
