OBJECTIVE: This study aimed to evaluate the clinical effect of trochanteric slide osteotomy (TSO) combined with a cementless femoral conical stem in THR for the treatment of Crowe type IV DDH. METHODS: Thirty-one total hip replacements (26 patients) with Crowe type IV DDH were performed using TSO combined with a cementless femoral conical stem. Surgical outcomes were evaluated using leg length discrepancy (LLD), Harris hip score, and post-operative complications. RESULTS: The average pre-operative LLD was 51\u00a0mm (range 46\u201358\u00a0mm), decreasing to an average of 10\u00a0mm (range 8\u201312\u00a0mm) post-operatively. As a result, the post-operative incidence of the Trendelenburg sign significantly decreased compared with the pre-operative incidence (P&lt; 0.05). Bony union was identified in 26 hips (83.9%), fibrous union in four (12.9%), and non-union in one (3.2%). No acetabular or femoral component loosening, dislocation, or deep infection around the component was found in any of the patients during the follow-up period (27 to 39 months). The average Harris hip score improved from 63.0 \u00b1 3.0 (range 58\u201369) to 93.3 \u00b1 2.0 (range 91\u201396). CONCLUSION: TSO combined with a cementless conical stem in THR is an appropriate option for patients with high congenital hip dislocation.<\/jats:p>","DOI":"10.3233\/thc-220147","type":"journal-article","created":{"date-parts":[[2022,9,16]],"date-time":"2022-09-16T14:05:28Z","timestamp":1663337128000},"page":"553-563","source":"Crossref","is-referenced-by-count":3,"title":["The
