Prior Lumbar Spinal Arthrodesis Increases Risk of Prosthetic-Related Complication in Total Hip Arthroplasty

Abstract Background Degenerative hip disorders often coexist with degenerative changes of the lumbar spine. Limited data on this patient population suggests inferior functional improvement and pain relief after surgical management. The purpose of this study is to compare the rates of prosthetic-rela...

Description
Summary:Abstract Background Degenerative hip disorders often coexist with degenerative changes of the lumbar spine. Limited data on this patient population suggests inferior functional improvement and pain relief after surgical management. The purpose of this study is to compare the rates of prosthetic-related complication following primary total hip arthroplasty (THA) in patients with and without prior lumbar spine arthrodesis (SA). Methods 811,601 Medicare patients undergoing primary THA were identified and grouped by length of prior SA (no fusion, 1-2 levels fused [S-SAHA], ≥3 levels fused [L-SAHA]). Results Compared to controls, patients with prior SA had significantly higher rates of complications including dislocation (control:2.36%; S-SAHA:4.26%; L-SAHA:7.51%), revision (control:3.43%, S-SAHA:5.55%, L-SAHA:7.77%), loosening (control:1.33%, S-SAHA:2.10%, L-SAHA:3.04%) and any prosthetic-related complication (control:7.33%, S-SAHA:11.15% (RR 1.52), L-SAHA:14.16% (RR 1.93)) within 24 months (p
