Aims There is evidence that prior lumbar fusion increases the risk of dislocation and revision
after total hip arthroplasty (THA). The relationship between prior lumbar fusion and the effect …

Background While continuous optimization is attempted to decrease the incidence of
dislocation after total hip arthroplasty (THA), dislocation remains a major complication. This …

Background context Effective alternatives to lumbar fusion for degenerative conditions have
remained elusive. Anterior total disc replacement does not address facet pathology or …

There is no universal safe zone for cup orientation. Patients with spinal arthrodesis or a
degenerative lumbar spine are at increased risk of dislocation. The relative contributions of …

Background: Lumbar spinal pathology is known to affect outcomes following total hip
arthroplasty (THA). However, the effect of hip osteoarthritis (OA) on outcomes following …

Study Design: This is a retrospective cohort study of consecutive patients undergoing lumbar
spinal fusion (LSF) within the PearlDiver Humana research database from 2010 to 2018 …

Background Prior spinal fusion significantly increases the risk of dislocation in patients after
total hip arthroplasty (THA). Owing to these high risks, surgeons may use dual-mobility (DM) …

Background Instrumented posterior lumbar spinal fusion (IPLSF) has been demonstrated to
contribute to instability following total hip arthroplasty (THA). It is unclear whether a supine …

The functional positioning of components in a total hip arthroplasty (THA) and its relationship
with individual lumbopelvic kinematics and a patient's anatomy are being extensively …

Spinopelvic mobility affects outcome after THA. Whether the sacro‐femoral‐pubic (SFP)
angle, measured on AP radiographs, can be reliably used to estimate pelvic tilt (PT) in hip …
