The hip-spine relationship and its effect on total hip arthroplasty outcomes: What do the databases show?

Abstract

The number of patients with degenerative disorders of both the hip and spine is increasing, as is our understanding of hip-spine interactions. Much of the work elucidating the effects of the interplay between the spine and hip joint, specifically as it relates to total hip arthroplasty, has come from database research. Database studies have demonstrated that patients with lumbar spinal pathology undergoing subsequent total hip arthroplasty are at increased risk for adverse outcomes including dislocation, aseptic loosening, fracture, lower patient reported outcome measures, and revision when compared to replacement patients without spinal disease.
