A New York City-based NYU Langone Medical Center study presented at the AAOS 2017 Annual Meeting in San Diego shows patients with spinal deformities are more likely to suffer hip dislocation or follow-up revision surgery after total hip replacement.
Here are five things to know:
1. Researchers found an 8 percent dislocation rate for hip replacements in spinal stenosis-afflicted patients; 5.8 percent of the same patient group required revision surgery due to recurrent dislocation.
2. When lying down, 78 percent of all study patients had normal artificial hip placement, a number that decreased to 58 percent when patients stood due to increases in spinopelvic tilt.
3. Researchers recommend orthopedic surgeons performing hip replacements collaborate with spine surgeon colleagues on preoperative planning to ensure successful operations.
4. Study co-author Jonathan Vigdorchik, MD, of NYU Langone said, "It is imperative that the degree of spinal deformity be a primary factor in preoperative planning of hip replacements."
5 Over 310,000 hip replacements are performed in the U.S. annually and rates have increased dramatically over the past two decades in 45-year-old to 64-year-old adults who are active and live longer lives than ever before.
