(HealthDay News) – For patients undergoing stand-alone lateral lumbar interbody fusion (LLIF) procedures, there is a significant association between the amount of coronal curve correction and increase in lumbar lordosis and the development of postoperative anterior thigh/groin pain, according to research published in the Sept. 1 issue of Spine.

Marios G. Lykissas, MD, PhD, from Weill Cornell Medical College in New York City, and colleagues conducted a retrospective analysis of 73 stand-alone LLIF procedures using medical records and spinal radiographs of 30 patients, reviewed during a six-year period. Participants underwent stand-alone LLIF for symptomatic degenerative scoliosis of the lumbar spine. Patients were followed for a median of 21 months.

Immediately after surgery, the researchers found that a motor deficit was recorded in six patients and a sensory deficit in 17 patients. The development of postoperative motor or sensory deficits was not significantly associated with the amount of coronal curve correction, restoration of lumbar lordosis, or increase in lumbar spine height. Immediately after surgery, 17 patients complained of anterior thigh/groin pain. Postoperative anterior thigh/groin pain was significantly associated with the magnitude of curve correction (P=0.005) and the increase in lumbar lordosis (P=0.04).

“There is a strong association between the development of postoperative anterior thigh/groin pain and the amount of coronal curve correction, as well as the increase in lumbar lordosis,” the authors write.
