Background The biomechanical relationship between the lumbar spine and the hip is well-
documented. It follows that fusing the lumbar spine would have implications on the …

Background: Many patients are affected by concurrent disease of the hip and spine,
undergoing both total hip arthroplasty (THA) and lumbar spinal fusion (LSF). Recent …

Background Patients undergoing primary total hip arthroplasty (THA) following lumbar spine
fusion have an increased incidence of dislocation compared to those without prior lumbar …

Background Lumbar-pelvic fusion reduces the variation in pelvic tilt in functional situations
by reducing lumbar spine flexibility, which is thought to be important in maintaining stability …

Background The purpose of this study was to determine whether the risk of dislocation
and/or revision following THA is increased in patients with a history of prior lumbar fusion …

Aims Lumbar fusion is known to reduce the variation in pelvic tilt between standing and
sitting. A flexible lumbo-pelvic unit increases the stability of total hip arthroplasty (THA) when …

Background The coexistence of degenerative hip disease and spinal pathology is not
uncommon with the number of surgical treatments performed for each condition increasing …

Aims Concurrent hip and spine pathologies can alter the biomechanics of spinopelvic
mobility in primary total hip arthroplasty (THA). This study examines how differences in …

Background Degenerative hip disorders often coexist with degenerative changes of the
lumbar spine. Limited data on this patient population suggest inferior functional …

Concomitant spine and hip disease in patients undergoing total hip arthroplasty (THA)
presents a management challenge. Degenerative lumbar spine conditions are known to …
