Psoas Muscle Impingement by a Lumbar Disc-Osteophyte Complex: A Case Report.

Psoas tendon impingement is not a frequently encountered condition, but impingement at the muscular level is not reported in the literature. The term refers to the mechanical impingement of the psoas muscle with secondary myositis. We report a case of psoas muscle impingement by a lumbar disc-osteophyte complex. This study reports on a 61-year-old female who presented to our facility complaining of severe low back pain with increased intensity in the past two weeks. Radiographic imaging and magnetic resonance imaging revealed psoas muscle impingement by lumbar disc-osteophyte. No signs of nerve compression or infection were found. The patient responded well to conservative treatment, including non-steroidal anti-inflammatory drugs and physical therapy. No studies have reported psoas impingement syndrome due to the lumbar disc-osteophyte complex. More research is needed to better understand this condition.
