Their mean age at the time of surgery was 40,36\u00b112,35. All patients underwent simultaneous, bilateral THA between January 2015 and December 2016. Clinical assessment included Oswestry disability index (ODI) score and Harris hip score (HHS), and pelvic incidence (PI), sacral slope (SS), lumbar lordosis (LL), and pelvic tilt (PT) were measured from radiographs.\n\nResults: Preoperatively, all the patients had hip and low-back pain. Preoperative and final follow-up ODI scores were 48.3 and 3.9 (p=0.000), respectively. HHS changed from 43.54 to 92.68 (p=0.000). PT and PI significantly changed from -20.4\u00b0\u00b120.4\u00b0 to 3.2\u00b0\u00b116.7\u00b0 (p=0.001) and from 26.6\u00b0\u00b135.1\u00b0 to 47.4\u00b0\u00b117.9\u00b0 (p=0.001), respectively. There were no significant differences regarding the SS and LL measurements. Age or limb-length discrepancy was not significantly associated with the spinopelvic alignment measurements.\n\nConclusion: Restoring the function of the hip with THA is shown to improve hip-associated LBP, but the accompanying hyperlordosis does not change. THA in patients with bilateral Crowe type-IV hips relieves hip pain as well as associated LBP. Hyperlordosis of the lumbar vertebra does not change after surgery, but PI and PT changes are observed; this improvement might have a role in the relief of LBP.\n\nLevel of Evidence: Level IV, Therapeutic study\n\nCite this article as: Can A, Erdo\u011fan F, Yontar NS, \u00d6v\u00fcl Erdo\u011fan A, Erdem MN, Sar\u0131kaya \u0130A.
