Lumbar Spine Fusion Before Revision THA Is Associated With I
A Study was conducted to determine whether timing of lumbar spinal fusion (LSF) before revision total hip arthroplasty (THA) would impact dislocation and rerevision rates.

This study includes a total of 505 patients who underwent revision THA with concomitant diagnosis of degenerative lumbar spinal stenosis with spondylolisthesis. Patients were stratified into the following two cohorts: (1) 328 patients who underwent revision THA with previous LSF and (2) 177 patients who underwent revision THA, followed by LSF. Postoperative complications including dislocation and rerevision rates were evaluated.

Results:
--Patients who underwent revision THA with previous LSF demonstrated significantly higher dislocation rates and rerevision rates compared with patients who underwent revision THA, followed by LSF, at the 1-year follow-up.

--Patients who underwent revision THA, followed by LSF within 1 year demonstrated significantly higher dislocation and rerevision rates.

Conclusively, study shows that patients who had revision THA followed by LSF had significantly higher dislocation and rerevision rates than patients who had revision THA followed by LSF, with the longer the interval between revision THA and LSF, the lower the postoperative dislocation and rerevision rates.
