When the cartilage that cushions the joint breaks down and ultimately wears away, typically in adults aged 45 and older, Hip arthritis usually occurs. Characterized by pain and stiffness, severe cases can be intensely debilitating. If the pain is impacting normal daily functioning and the ability to get a good night’s sleep and above all, if conventional treatments for hip joint pain fail to bring respite total then hip replacement surgery (arthroplasty) may be recommended.
The operation is usually performed under sectional anesthesia. The surgeon takes away injured cartilage and bone, then places new metal, plastic or ceramic joint surfaces to reconstruct the joint. An artificial joint includes two basic components: the ball (made of an extremely polished strong metal or ceramic material) and the socket (a sturdy cup of plastic or ceramic). Special surgical cement is normally used to protect the artificial joint in place.
In a few instances, in younger, more active patients, a non-cemented type of prosthesis is made use of. This prosthesis is made such that the bone will nurture into and assimilates with the porous surface of the implant. Sometimes, a blend of a cemented ball and a non-cemented socket is used.
You will probably be recommended for surgery, in case if you are experiencing the following symptoms:
1. Pain that averts you from walking or bending the joint.
2. Pain while you are at rest, either during day or night
3. Stiffness in your hip that averts from lifting your leg.
4. No respite from non-surgical treatment techniques.
This surgery can be performed conventionally or by using what is considered a nominally-invasive procedure. The key difference between the two techniques is the extent of the incision. Patients are administered general anesthesia in standard hip replacement surgery, to relax their muscles and put them into a temporary deep sleep. This will prevent the sensation of any pain at the time of the surgery or maintain no awareness of the procedure. A spinal anesthetic may be administered to help avoid pain as an option.
The surgeon will then make a cut along the side of the hip and push the muscles linked to the top of the thighbone to expose the hip joint. Next, the ball portion of the joint is detached by cutting the thighbone with a saw. Then an artificial joint is placed to the thighbone by means of either cement or a special material that lets the other bone to attach to the new joint.
The surgeon then readies the surface of the hipbone — eliminating any injured cartilage — and assigns the replacement socket part to the hipbone. The new ball part of the thighbone is then implanted into the socket portion of the hip. A drain may be placed in to allow drain any fluid. The surgeon then reattaches the muscles and closes the incision.
While maximum hip replacement surgeries these days are done with the standard procedure, in recent years, few surgeons have been applying a minimally-invasive procedure. In this method, surgeons opt for one or two cuts from 2 to 5 inches in length. The same technique is used through these small cuts as with standard hip replacement surgery.
