However, it is usually only done on men who are very active and have larger hips. Resurfacing is much less popular now due to concerns about the metal surface causing damage to soft tissues around the hip. Preparing for hip replacement surgery, Before you go into hospital, find out as much as you can about what's involved in your operation.
Stay as active as you can. Strengthening the muscles around your hip will help your recovery. If you can, continue to do gentle exercise, such as walking and swimming, in the weeks and months before your operation. You may be referred to a physiotherapist, who will give you helpful exercises.
Some people may require revision surgery to repair or replace the joint. Find out more about the risks of a hip replacement. Metal-on-metal implants, There have been cases of some metal-on-metal (Mo, M) hip replacements wearing out sooner than expected, causing deterioration in the bone and tissue around the hip.
Get more advice about a metal-on-metal implant. The National Joint Registry, The National Joint Registry (NJR) collects details of hip replacements done in England, Wales, Northern Ireland and the Isle of Man. Although it's voluntary, it's worth registering. This enables the NJR to monitor hip replacements, so you can be identified if any problems emerge in the future.
Hip replacements help millions of people regain mobility and find relief from joint pain, but hip replacement surgery is accompanied by some risk and requires months of recovery. Prospective patients should know that implants don’t last forever, and some hip implants have a better safety record than others. They should take steps to be sure a hip replacement is right for them and that the device they’re receiving has a history of success.
The ball, also called a femoral head component, replaces the head of the femur. The cup, also called the acetabular component, is implanted into the pelvis. In a healthy hip, the head of the femur bone fits securely in the acetabulum, forming the hip joint. Hip replacements are one of the most common joint replacement operations in the United States, with more than 300,000 performed in the country each year, according to the American Academy of Orthopaedic Surgeons.
5 million Americans were living with artificial hips in 2010, according to a study published in 2015 in The Journal of Bone and Joint Surgery. Although hip replacement surgery is common, it is a major surgery that has a variety of risks. Complications during surgery or later in life can cause debilitating side effects.
Many people experience pain relief and improvements in daily living after receiving a hip replacement, but the devices are not miracle cures. Hip replacement surgery has a number of risks, and the implants wear out over time. To avoid complications, people who receive implants should not jog, run or participate in high-impact sports.
Exercises that increase muscle around the hip Canes, walkers and other walking aids Over-the-counter medication for pain without inflammation Nonsteroidal anti-inflammatory drugs for pain with inflammation Osteotomy of the femur, a procedure that involves cutting and realigning the bone But when alternative treatments do not provide relief, increase mobility or improve quality of life, doctors may consider a hip replacement procedure.
They may also conduct MRIs or CT scans. Types of Hip Replacement Surgery Surgeons perform hip replacements by using a posterior approach or an anterior approach. With a posterior hip replacement, the incision is made at the side or back of the hip. During anterior hip replacement, the surgeon makes the incision at the front of the hip.
There is no significant difference between the procedures as far as recovery from surgery, but the anterior procedure may pose a higher risk of nerve damage that could cause numbness in the outer thigh. Patients who are younger than 50, have a normal body mass index or who are in overall good health may be candidates for minimally-invasive surgery.
Special bone cement is commonly used to hold hip implants in place, but some surgeons use a cementless fixation technique. Devices that do not require cement have a textured surface that allows the bone to grow onto the implant and secure it. A hybrid total hip replacement involves implanting the cup without cement and setting the ball in place with cement.
It uses artificial components to replace the entire hip structure. During the procedure, surgeons insert a stem into the patient’s femur, or thighbone, for stability. They replace the head of the femur with a ball and replace the natural socket in the hip joint with an artificial cup. Partial Hip Replacement Partial hip replacement removes and replaces the patient’s femoral head, which is the ball at the top of the femur, or thighbone.
The surgeon also lines the natural bone socket of the hip with a metal lining or shell. Bilateral Hip Replacement vs. Staged Hip Replacements If both hips require replacement, surgeons may choose a staged hip replacement. They replace one hip at a time, letting the patient recover from the first surgery before doing the second one.
A bilateral hip replacement can mean a single trip to the operating room and the potential for less overall recovery time. But it doesn’t work for all patients. The risk of blood loss during surgery is greater with bilateral hip replacement and patients are under anesthesia for twice as long — up to four hours.
Metal-on-Polyethylene (Mo, P) One of the most common types of hip implant, metal-on-polyethylene has been used since the 1960s. The ball is made of metal and the socket has a plastic lining or is made entirely of polyethylene. Plastic has a smooth surface that causes little friction while the ball moves within the socket.
Wear debris from the breakdown of materials could lead to a condition called osteolysis, which occurs when inflammation destroys the bone and the implant in the bone loosens. Metal-on-Metal (Mo, M) Metal-on-metal hip devices are no longer available in the United States, though thousands of people may have been implanted with them.
The first involves certain implants with metal-on-metal bearings that are associated with a higher risk for failure and metal release from the bearing’s surface. The other major class of concern involves metal-on-polyethylene bearings that release metal debris where the pieces of the stem or head come together. “The reactions are similar: inflammation around the joints, fluid collections, and in more advanced cases, tissues damage, bone loss or some of the more rare but serious complications like blood vessel constriction or compressions,” Cooper said.
But there are still plenty of patients in the United States who have these devices inside of them, Cooper said. Some patients in the United States are walking around with implants that were not available in the United States but were available in Europe or in other countries, and they are having the same kinds of problems.
Some implants wear out faster than others, requiring revision surgery to remove, repair or replace the device. An estimated 10. 4 percent of hip replacements require revision surgery, according to a 2016 study published in Arthroplasty Today. Lawsuit Information Revision surgery is one of the injuries named in hip replacement lawsuits.
The problem came from the connections in the stem that held the implant to the femur. The Stryker devices came with different sized and angled necks that allowed surgeons to customize fit for patients. The junction where these connected shed particles into patients’ tissue. United Kingdom-based Smith & Nephew recalled all 6,266 lots of its Modular Redapt Hip Systems in 2016 due to “a higher than anticipated complaint and adverse event trend.” Just a year earlier, the company had recalled almost 6,000 Birmingham Hip Resurfacing, or BHR, components due to “revision rates which were higher than established benchmarks.” Zimmer recalled 19,000 Durom cup components in 2008 because of false and misleading labeling.
The devices had higher than expected failure rates. Problems led companies to recall some models. Others were simply pulled off the market. Today, there are no FDA-approved metal-on-metal hip implants available in the United States. There are only two FDA-approved metal-on-metal resurfacing systems available. And any company that wants to sell metal-on-metal hips can no longer rely on the 510(k) process.
