The purpose of this study was to analyse the incidence of stress fracture after Bernese PAO under the care of two high-volume surgeons. The study included 359 patients (48 men, 311 women) operated on at a mean age of 31.1 years (15 to 56), with a mean follow-up of 26 months (6 to 64). Complete follow-up radiographs were available for 348 patients, 64 of whom (18.4%) developed a stress fracture of the inferior pubic ramus, which was noted at a mean of 9.1 weeks (5 to 55) after surgery. Most (58; 91%) healed. In 40 of the patients with a stress fracture (62.5%), pubic nonunion also occurred. Those with a stress fracture were significantly older (mean 33.9 years (16 to 50) vs 30.5 years (15 to 56), p = 0.002) and had significantly more mean pre-operative deformity: mean centre\u2013edge angle (9.8\u00b0 (-9.5 to 35) vs 12.4\u00b0 (-33 to 28), p = 0.04) and mean T\u00f6nnis angle (22.8\u00b0 (0 to 45) vs 18.7\u00b0 (-2 to 38), p &lt; 0.001). The pubic nonunion rate was significantly higher in those with a stress fracture (62.5% vs 7%, p &lt; 0.001), with regression analysis revealing that these patients had 11.8 times higher risk than those without nonunion. <\/jats:p><jats:p> Cite this article: Bone Joint J 2015; 97-B:24\u20138. <\/jats:p>","DOI":"10.1302\/0301-620x.97b1.34525","type":"journal-article","created":{"date-parts":[[2015,1,7]],"date-time":"2015-01-07T23:06:53Z","timestamp":1420672013000},"page":"24-28","update-policy":"https:\/\/doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":44,"title":["The incidence of stress fracture following peri-acetabular osteotomy"],"prefix":"10.1302","volume":"97-B","author":[{"given":"A.","family":"Malviya","sequence":"first","affiliation":[{"name":"Northumbria Healthcare NHS Foundation\rTrust, Wansbeck General Hospital, Woodhorn\rLane, Ashington, NE63\r9JJ, UK."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.","family":"Dandachli","sequence":"additional","affiliation":[{"name":"Guy\u2019s and St Thomas\u2019 Hospital, London, 1st\rFloor, Bermondsey Wing, Guy\u2019s\rHospital, Great Maze Pond, London\rSE1 9RT, UK."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Z.","family":"Beech","sequence":"additional","affiliation":[{"name":"Southampton University Hospitals NHS Trust, Tremona\rRoad, Southampton SO16 6YD, UK."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
