This study evaluated changes in spinopelvic parameters following primary THA and their association with post-operative functional outcome.\n\nMaterials and Methods:\nThis prospective observational study included 80 patients undergoing primary THA at a tertiary care teaching hospital between April 2024 and June 2025. Demographic characteristics, spinopelvic parameters in standing, sitting, lateral decubitus, and lateral decubitus with 90\u00b0 hip flexion positions, and Harris hip score (HHS) were assessed preoperatively and postoperatively. Functional outcomes were evaluated at 2 days, 14 days, 3 months, and 6 months after surgery. Correlations between spinopelvic parameters and HHS were analyzed using Pearson\u2019s correlation coefficient.\n\nResults:\nThe mean age of the patients was 48.33 \u00b1 6.29 years, with males accounting for 60.0% of the study population. Significant post-operative improvements were observed in pelvic tilt (PT), sacral slope (SS), lumbar lordosis, and pelvic femoral angle (PFA) across different functional positions (all P &lt; 0.05), whereas pelvic incidence (PI) remained unchanged (P = 0.87). Mean HHS improved significantly from 42.80 \u00b1 6.50 preoperatively to 90.35 \u00b1 4.75 at 6 months (P &lt; 0.0001). PT demonstrated a significant negative correlation (r = \u22120.36, P = 0.010), while SS (r = 0.41, P = 0.003), PI (r = 0.39, P = 0.005), and PFA (r = 0.33, P = 0.018) showed significant positive correlations with functional outcome. All acetabular components were positioned within the Lewinnek safe zone.\n\nConclusion:\nPrimary THA significantly improved spinopelvic alignment and hip function. Several spinopelvic parameters were significantly associated with post-operative functional outcome, highlighting the importance of comprehensive spinopelvic assessment during pre-operative planning and post-operative evaluation.\n\nKeywords:\nTotal hip arthroplasty , spinopelvic alignment , pelvic tilt , Harris hip score , functional outcome , sacral slope<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i10.8286","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T16:58:11Z","timestamp":1791392291000},"page":"345-352","source":"Crossref","is-referenced-by-count":0,"title":["A Study of Spinopelvic Relationship and its Impact on Functional Outcome of Total Hip Arthroplasty"],"prefix":"10.13107","volume":"16","author":[{"given":"Parv","family":"Bhargava","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, People\u2019s College of Medical Sciences and Research Centre, Bhopal, Madhya Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harish","family":"Rao","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, People\u2019s College of Medical Sciences and Research Centre, Bhopal, Madhya Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mrudul","family":"Shah","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, People\u2019s College of Medical Sciences and Research Centre, Bhopal, Madhya Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohit","family":"Dashore","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, People\u2019s College of Medical Sciences and Research Centre, Bhopal, Madhya Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ravi","family":"Mehrotra","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, People\u2019s College of Medical Sciences and Research Centre, Bhopal, Madhya Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syed Tariq","family":"Mahmood","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, People\u2019s College of Medical Sciences and Research Centre, Bhopal, Madhya Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T16:58:12Z","timestamp":1791392292000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/10\/a-study-of-spinopelvic-relationship-and-its-impact-on-functional-outcome-of-total-hip-arthroplasty\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"10","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i10.8286","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]}}}
