You are correct! You are incorrect!

All of these conditions could lead to a hip replacement.  Osteoarthritis is a long-term degenerative condition; RA is a chronic autoimmune disease that attacks the joint; Paget's disease can cause bone pain, fracture, deformity, and nerve pain; and a broken hip can necessitate a replacement if the conditions are severe enough.

  1. Which of the following conditions could require a hip replacement?

    Correct Answer: All of the above

    All of these conditions could lead to a hip replacement.  Osteoarthritis is a long-term degenerative condition; RA is a chronic autoimmune disease that attacks the joint; Paget's disease can cause bone pain, fracture, deformity, and nerve pain; and a broken hip can necessitate a replacement if the conditions are severe enough.

  2. Which of these doctors will NOT tell a patient when a hip replacement is necessary?

    Correct Answer: Ophthalmologist

    An ophthalmologist is a specialist with the anatomy, physiology and diseases of the eye.  The other three doctors are qualified to do so.

  3. A patient should be able to walk normally around ___ weeks after hip replacement surgery.

    Correct Answer: 6

    Though each patient is different, most hip replacement recipients are walking normally within 6 weeks of surgery.

  4. How is the mini-incision anterior approach to a hip replacement different from the traditional posterior approach?

    Correct Answer: Less muscle and tendon damage

    The mini-incision anterior approach uses a single, smaller incision as compared to a large incision or multiple incisions, though it does require a special table (Judet table) and specific tools (e.g., a curved reamer).  The advantage to this approach is that it is atraumatic and preserves muscles and tendons, which allows for faster recovery.  Both cemented and uncemented prosthesis work with this procedure.

  5. Which implant material is most modern and technologically advanced?

    Correct Answer: Ceramic ball, ceramic liner

    Ceramic-on-ceramic is the hardest implant and has the lowest wear-rate to the point where it is virtually immeasurable.  This is the most technologically advanced of the options.

  6. Exercise is required …

    Correct Answer: Throughout the entire process

    Exercise is necessary for the success of this procedure.  Though exercises vary – beginning when the patient is still in the hospital, through physical therapy, and continuing on forever – it is paramount that a patient keep the joint in strong working condition.
