Hip resurfacing is the procedure done for the replacement of the articular surface of the joint. It is different from the hip replacement, where the neck of the thighbone or femur would be removed and replaced surgically. In the resurfacing method, trimming of femoral head is done and then a small cap is placed for covering of the metal. Hip resurfacing is a good choice for the candidates, who are at advanced arthritis.
Selection of the candidates
- When the candidates have been suffering long from advanced osteoarthritis and nonsurgical treatments are not helpful
- Preferred for younger candidates having healthy and strong bone
- Preferred for larger-framed candidates having healthy and strong bone
It is not suggested for the female, weaker, smaller-framed and damaged bone candidates, as they are more susceptible to femoral neck fracture.
The candidate is evaluated by the doctor and also by the anesthesia professionals, by evaluating the medical history. You would be discussed for the possible anesthesia choices by them before the resurfacing procedure. You would also be discussed the procedure and pre operative clinic visits. The surgical site, the hip is seen by the surgeon.
The procedure starts with the anaesthesia given, either spinal or general according to your choice. Spinal anesthesia makes you awake, the waist would be numbed. General anesthesia is given for the candidate to sleep entire for the process.
Small incisions are made at the thigh so that it reaches the hip joint. The femoral head would then be dislocated from its socket. A power instrument that is specially designed, is used to trim this head. The cartilage, which is used for lining the socket will then be removed with the help of reamer, which is a power tool. Then a right size metal cup is pushed and positioned in the socket. It would then be held in the position by friction in between the metal and bone. After the cup is positioned, the femoral head that was removed before would then be relocated in the socket. The incision will be closed.
After the surgery is completed, the patient will be transferred to the recovery room. The patient is closely monitored after relieving or recovering from anesthesia. Then the candidate will be placed in the hospital room.
Hip resurfacing also has the similar risks and complications like surgical procedure. The following complications are possible, which can be avoided with the careful pre, post and surgical procedures.
- Blood clot
- Femoral neck fracture
- Risks of anesthesia
Most likely, the patient will be discharged from the hospital in 1 to 4 days after the surgery is completed. The time for putting the weight on the leg would be determined by the surgeon. It depends on various factors, like complications of the surgery, strength of the bone. Initially, a crutch, cane or walker might be needed for a few days or for a few weeks, based on the comfort and strength of the bone. A physical therapist suggests the exercises needed to maintain the motion and its range and also to restore the strength. The candidate needs to meet the orthopeaedic surgeon during the follow-up visits, regularly.
It takes around 6 weeks of duration to go back to the regular daily activities.
- Hip resurfacing is usually easier and the revision would also be easier.
- The risk of dip dislocation can be minimized.
- The walking pattern would be more normal after the resurfacing procedure.
- The hip range of motion would be greater.
- There is a probability of femoral neck fracture.
- The risk of metal ion is more here.
- The operation or procedure conducted for the hip resurfacing is more difficult, when compared to the replacement.
