ABSTRACT
Background: Hip osteoarthritis (OA) is common in patients with adult spinal deformity (ASD). Limited data exist on the prevalence of hip OA ASD, or its impact baseline and postoperative alignment patient-reported outcome measures (PROMs). Therefore, this paper will assess PROMs. Methods: Patients ASD who underwent L1-pelvis longer fusions were included. Two independent reviewers graded Kellgren-Lawrence (KL) classification stratified it by severity into non-severe (KL grade 1 2) severe 3 4). Radiographic parameters PROMs compared among patient groups: Hip-Spine (hip KL 4 bilaterally), Unilateral (UL)-Hip unilaterally), Spine 2 bilaterally). Results: Of 520 met inclusion criteria for an analysis, 34% (177 520) had bilateral unilateral arthroplasty been performed 8.7% (45 520). A subset 165 all components examined: 68 Hip-Spine, 32 UL-Hip, 65 Spine. older (67.9 ± 9.5 years, versus 59.6 10.1 years 65.8 7.5 UL-Hip; p < 0.001) a higher frailty index (4.3 2.6, 2.7 2.0 UL-Hip 2.9 Spine; 0.001). At year, groups similar lumbar lordosis, yet worse sagittal vertebral axis (SVA) measurement (45.9 45.5 mm, 25.1 37.1 mm 19.0 39.3 = also Veterans RAND-12 Physical Component Summary scores at (25.7 9.3, 28.7 9.8 31.3 10.5 0.005) year postoperatively (34.5 11.4, 40.3 10.4 40.1 10.9 0.006). Conclusions: This study operatively treated revealed that bilaterally. Such SVA persisted following surgery, despite correction lordosis. Level Evidence: Prognostic III .
