There were 23 men and 26 women with a mean age of 44.3\u2009years at the time of surgery. The following clinical outcomes were evaluated: the Western Ontario and McMaster Universities Arthritis Index (WOMAC) score, Harris hip score (HSS), modified Merle d'Aubigne\u2010Postel hip (MAP) score, low back pain visual analog scale score, 12\u2010item short\u2010form health survey questionnaire score, limp, and Trendelenburg sign. Radiographic outcomes and complications were also evaluated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean follow\u2010up period was 8.7\u2009years (range, 5.5\u201310\u2009years). No infection recurrence was observed after THA. The average HSS significantly improved from 45.0 to 84.8. The WOMAC score improved from 70.1\u2009\u00b1\u20093.5 (range, 65\u201376) to 43.1\u2009\u00b1\u200913.4 (range, 21\u201367). The modified MAP score improved from 5.9\u2009\u00b1\u20091.9 (range, 3\u20139) to 14.3\u2009\u00b1\u20092.4 (range, 11\u201318). The low back pain visual analog scale score, 12\u2010item short\u2010form health survey questionnaire score, limp, and Trendelenburg sign also improved significantly. The average limb length discrepancy decreased from 39.6\u2009mm (range, 30\u201355\u2009mm) to 7.2\u2009mm (range, 0\u201322\u2009mm). Two patients had temporary sciatic nerve paralysis but recovered within 6\u2009months without any functional defects; one had an intraoperative fracture fixed by cerclage wires. One hip required revision surgery because of femoral stem aseptic loosening.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The cementless S\u2010ROM modular femoral stem used with subtrochanteric transverse shortening osteotomy is safe and effective for high hip dislocation secondary to pyogenic arthritis and provides satisfactory midterm results.
