This could be avoided by inclining the osteotome 45\u00b0 medially and performing the osteotomy at least 2 cm medial to the iliopectineal eminence. <\/jats:p><jats:p> The sciatic nerve could be injured during the first and last stages of the osteotomy if the osteotome perforated the lateral cortex of ischium and the ilio-ischial junction by &gt; 10 mm. <\/jats:p><jats:p> The femoral nerve could be stretched or entrapped during osteotomy of the pubis if there was significant rotational or linear displacement of the acetabulum. Anterior or medial displacement of &lt; 2 cm and lateral tilt (retroversion) of &lt; 30\u00b0 were safe margins. The combination of retroversion and anterior displacement could increase tension on the nerve. <\/jats:p><jats:p> Strict observation of anatomical details, proper handling of the osteotomes and careful manipulation of the acetabular fragment reduce the neurological complications of Bernese peri-acetabular osteotomy. <\/jats:p><jats:p> Cite this article: Bone Joint J 2015;97-B:636\u201341. <\/jats:p>","DOI":"10.1302\/0301-620x.97b5.35084","type":"journal-article","created":{"date-parts":[[2015,5,8]],"date-time":"2015-05-08T16:15:47Z","timestamp":1431101747000},"page":"636-641","update-policy":"https:\/\/doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":36,"title":["Reducing the risk of nerve injury during Bernese periacetabular osteotomy"],"prefix":"10.1302","volume":"97-B","author":[{"given":"M.","family":"Kalhor","sequence":"first","affiliation":[{"name":"Firoozgar Medical Centre, Iran University\rof Medical Sciences, Behafarin Street, Tehran\r48711, Iran."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Gharehdaghi","sequence":"additional","affiliation":[{"name":"Legal Medicine Organisation, Behesht\rStreet, Khayyam Avenue, Tehran\r11144, Iran."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Schoeniger","sequence":"additional","affiliation":[{"name":"Luzerner Kantonsspital, 6000\rLuzern, Switzerland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Ganz","sequence":"additional","affiliation":[{"name":"University of Bern, Walchstrasse\r10, 3073 Guemligen, Bern, Switzerland."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"42","reference":[{"key":"r1","first-page":"26","volume":"232","author":"Ganz R","year":"1988","journal-title":"Clin Orthop Relat Res"},{"key":"r2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199906000-00003"},{"key":"r3","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199906000-00007"},{"key":"r4","first-page":"239","volume":"50","author":"Siebenrock KA","year":"2001","journal-title":"Instr Course Lect"},{"key":"r5","first-page":"229","volume":"50","author":"Leunig M","year":"2001","journal-title":"Instr Course Lect"},{"key":"r6","doi-asserted-by":"publisher","DOI":"10.1080\/00016470310013824"},{"key":"r7","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.D.02093"},{"key":"r8","doi-asserted-by":"crossref","first-page":"1920","DOI":"10.2106\/00004623-200608000-00007","volume":"88","author":"Peters CL","year":"2006","journal-title":"J Bone Joint Surg [Am]"},{"key":"r9","doi-asserted-by":"crossref","first-page":"1417","DOI":"10.2106\/00004623-200707000-00002","volume":"89","author":"Clohisy JC","year":"2007","journal-title":"J Bone Joint Surg [Am]"},{"key":"r10","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.89B6.18805"},{"key":"r11","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-008-0242-3"},{"key":"r12","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-009-0842-6"},{"key":"r13","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-34746-7_102"},{"key":"r14","first-page":"21","volume":"363","author":"Matta JM","year":"1999","journal-title":"Clin Orthop Relat Res"},{"key":"r15","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199907000-00013"},{"key":"r16","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200209000-00012"},{"key":"r17","doi-asserted-by":"publisher","DOI":"10.3109\/10929080209146028"},{"key":"r18","first-page":"38","volume":"74","author":"Pogliacomi F","year":"2003","journal-title":"Acta Biomed"},{"key":"r19","doi-asserted-by":"publisher","DOI":"10.2174\/1874325000701010013"},{"key":"r20","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.I.00829"},{"key":"r21","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199906000-00005"},{"key":"r22","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-200207000-00020"},{"key":"r23","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199906000-00011"},{"key":"r24","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-012-2409-1"},{"key":"r25","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-199808000-00004"},{"key":"r26","first-page":"64","volume":"363","author":"Hussel JG","year":"1999","journal-title":"Clin Orthop Relat Res"},{"key":"r27","first-page":"50","volume":"6","author":"Vrahas M","year":"1992","journal-title":"J Orthop Trauma"},{"key":"r28","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-199701000-00002"},{"key":"r29","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-200205000-00002"},{"key":"r30","doi-asserted-by":"publisher","DOI":"10.1007\/s11420-013-9347-7"}],"container-title":["The Bone &amp;
