Editorial Commentary: The Hip-Spine Connection in Patients Undergoing Hip Arthroscopy: Should We Learn From Total Hip Replacement and Counsel Patients Differently If They Have Had Previous Back Surgery?

Disorders of the adult hip and spine are common, and there is evidence that there is a hip-spine connection in patients with hip femoroacetabular impingement (FAI). Many reports have shown that patients undergoing lumbar fusion and subsequent total hip arthroplasty have a higher risk of complications and worse outcomes following total hip arthroplasty. However, there has been a paucity of research on the effect of a history of lumbar spine surgery in patients undergoing hip arthroscopy for the treatment of FAI. Variations in lumbar lordosis, pelvic incidence, tilt, and sacral slope may modify the degree of FAI, symptoms, and patient-reported outcomes following hip arthroscopy. In the future, we should continue our efforts to better understand the impact that limited range of motion in the spine has in joint mechanics of the hip and the possibility of affecting patient-reported outcomes after hip arthroscopy. Future studies incorporating novel imaging technology, such as EOS, may be an objective way of assessing the effect of abnormal spine-pelvic function in patients with hip FAI.
