In sorting out persistent pain around the hip, infection is a distinct but uncommon diagnosis reported to occur in less than 1% of all total hips ever getting infected in most studies of this issue. Fortunately, there are many other causes for pain around the hip joint other than infection, but infection always remains a diagnosis that must be considered in dealing with painful hip replacements.
Nevertheless, as a cause leading to revision hip replacement, infection is the third most common. In several studies which assess the causes of primary hip replacement failure, infection of the joint is the most challenging and potentially devastating cause with 15% of all revision hip replacement procedures being done for this reason . If an artificial joint becomes infected, the pain is typically more constant than with a loose, but non-infected joint, but symptoms greatly vary with the type of infecting organism. Along with pain, symptoms include a stiffening of the joint, making movement quite difficult. On rare occasion, a prosthetic joint infection can make the patient systemically ill with fever, chills, weight loss, and lethargy.
Infection of a hip replacement can occur at any time after surgery, sometimes many years after surgery. The risk, however, is higher in the first few weeks following a surgical procedure. A sudden change in the pain around a hip that has otherwise been recovering normally should be investigated. The challenge in this situation is that many of the laboratory studies will not be helpful in sorting out normal healing from a low-grade infection. Superficial wound infections are typically identified by a dramatic change in the appearance of the incision, but a deep infection around the joint itself can be hard to prove without some interventional study.
Even if the positioning of the components is optimal and the muscles are functioning normally, it is possible to put the leg in a position that forces the ball out of the socket, a conditioned referred to as hip dislocation. Statistically this happens at a rate of about one in 25 hip replacements. This is more common when the hip is implanted using a posterior approach, which weakens the soft tissue structures supporting the back of the hip joint. The dislocated hip can often be relocated with sedation of the patient and closed manipulation of the hip back into position without a repeat surgical procedure.
In most hip replacements there is a metal stem that is fixed inside the tube-like femur (thigh bone) upon which is perched an articulating ball bearing; and a metal cup that is fixed within the acetabulum of the pelvis (socket) containing a bearing surface on the opposite side within which rides the ball bearing. The socket bearing surface is commonly a plastic (polyethylene) or a ceramic (glass); the ball bearing is commonly a highly polished metal or ceramic. Each of these come is variable sizes and are mixed and matched by the surgeon for various mechanical properties and chosen as each situation demands.
Once the decision is made that a hip is infected, the surgical plan is typically as follows involving a two-stage technique. An infected joint routinely requires the removal of all parts of the hip replacement from the bone so that the infection can be cleared. The space occupied by the removed hip prosthesis is filled with an antibiotic laden cement spacer shaped like a hip prosthesis. This spacer serves to keep the soft tissues stretched out to proper length and provides antibiotic which leaches out of the cement spacer directly to the infected area over time. In addition, 6-12 weeks of IV antibiotics are given, depending upon the infecting organism. Once this treatment is completed, it is commonly possible, through a second operation, to implant a new hip replacement into the now sterilized hip area.
For a hip replacement to function well, the ball must be retained within the socket at all times. Several factors must work in concert to keep this mechanical relationship intact, including proper alignment of the acetabular prosthesis (the socket) and the femoral prosthesis (articulating ball part). In addition, the muscles that attach to both the pelvis and the femur must be strong and able to withstand pressure. Sometimes the muscles of the elderly patient are quite weakened with age or health related issues and are unable to hold the ball in the socket.
Although this complex series of surgical events frequently can salvage an infected hip replacement, there is still a high re-infection rate, with some estimates giving a disappointing 10 -15% of hips revised for infection staying infected . Persistent infection in a hip joint presents difficult decisions for the patient and the surgeon and each circumstance will require unique and individualized consideration.

A fracture may occur to the tube-like femur bone within which is fixed the femoral prosthesis with either bone cement or biologic attachment, or to the supporting bone of the pelvis to which is fixed the acetabular prosthesis. There is a wide variety of fracture patterns which occur, each having many possible solutions. A patient’s age, activity level and overall health will be weighed along with the various options to repair a fracture around a hip replacement.
