Ask Dr. Hansen: Who Gets a Partial Hip Replacement?

Dr. Hansen describes the perfect candidates for a partial hip replacement.

Hip pain can be debilitating. When conservative treatments do not effectively control pain, patients contemplate their surgical options. Currently, there are two joint replacement options: a total hip joint replacement and a partial hip replacement. How do you decide which surgery is best for you? Hip specialist Dr. Dane Hansen explains what a partial hip surgery is and describes the patients who benefit most from this treatment.

What is a partial hip replacement surgery?

“A partial hip replacement is what it sounds like: a replacement of part of the hip joint” says Dr. Hansen. “The part of the hip replaced is the ball or head of the hipbone. A partial hip surgery leaves the patient’s hip socket intact.”

The evolution of hip replacement surgery

Partial hip surgeries have been a treatment option since the initiation of joint procedures. “Early on, partial hips were used to treat a lot of different scenarios,” explains Dr. Hansen. “We used them to treat patients with avascular necrosis. Partial hips were also used for issues where the ball of the hipbone was damaged, but the hip socket still had healthy cartilage. Today, however, partial hip procedures are done far less often. That’s because the longevity and outcome of total hip replacements has improved markedly.”

“In the past,” remembers Dr. Hansen, “we’d discourage a younger patient from having a total hip replacement because we knew these implants wore out in 10 or 15 years. Instead, we’d recommend a partial hip replacement. This was the best available option even though a partial hip increased the risk of arthritis in the hip socket and eventually wore the socket down. At that point, we’d perform another surgery to give the patient a full hip replacement.”

Today, surgical recommendations have changed because the longevity of total hip replacements is so much better. “Implant technology is so good that even young, active patients can expect their total hip replacement to last for 25 to 30 years and possibly longer,” notes Dr. Hansen. “Advances in technology have transformed total hip replacement into a long-term solution. But there is still a place for partial hip replacement within a specific population of patients.”

The ideal partial hip replacement candidate

“Today, there is one narrow but significant indication for a partial hip surgery,” says Dr. Hansen. “Elderly patients who have fallen and suffered a hip fracture are ideal candidates. Hip fractures in this population are very common. Typically, the injury is characterized by a break through the neck of the femur just below the ball of the hipbone. The consequences of this break mirror the consequences of avascular necrosis: the blood supply to the head of the hipbone is compromised. Consequently, it’s almost impossible to fix the fracture and get the bones to heal together. That’s why a partial hip is the perfect solution. We remove the ball altogether and replace it with a partial hip implant.”

Benefits of a partial hip replacement

Dr. Hansen explains that a partial hip provides several advantages for elderly hip fracture patients.

Surgical recommendations are always tailored to patient needs

“A partial hip is an excellent option to quickly and safely treat a hip fracture in elderly patients with limited mobility,” says Dr. Hansen. “That said, it’s still important to make surgical decisions based on a patient’s unique circumstances. Because total hip replacements are so successful, I’ll consider them for any active patient who has highly cognitive function. There is a constantly shifting line between patients who should get a partial hip replacement and those who should get a full hip replacement. If you are an actively functioning, independent 75-year-old with a life expectancy of 10-plus years, I will at least have a conversation about whether you want a partial or a total hip replacement.”
