Eight months later, the lag screw had migrated medially into the pelvis and was in contact with the internal iliac vessels. After a multidisciplinary team meeting, embolization of the internal iliac artery was carried out prophylactically before the removal of screw and conversion to a total hip replacement.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Although there are increasing number of case reports on late medial migration of lag screw, medial migration into pelvis with vascular complication is a very rare complication with 1 case report in the literature. The authors would like to make the orthopaedic community aware of this rare but potentially fatal complication and present the option for successful management.<\/jats:p>\n <\/jats:sec>","DOI":"10.2106\/jbjs.cc.19.00623","type":"journal-article","created":{"date-parts":[[2020,9,1]],"date-time":"2020-09-01T15:56:01Z","timestamp":1598975761000},"page":"e19.00623-e19.00623","source":"Crossref","is-referenced-by-count":2,"title":["Late Medial Migration of Lag Screw After Gamma3 Nailing Threatening the Internal Iliac Vessels"],"prefix":"10.2106","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7924-6078","authenticated-orcid":false,"given":"Rajesh","family":"Pawar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2740-3654","authenticated-orcid":false,"given":"Prasad","family":"Antapur","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2020]]},"reference":[{"issue":"8","key":"bib2-20230720","doi-asserted-by":"crossref","first-page":"1275","DOI":"10.1016\/j.injury.2014.04.016","article-title":"Medial migration of lag screw after gamma nailing","volume":"45","author":"Thein","year":"2014","journal-title":"Injury."},{"issue":"9","key":"bib3-20230720","first-page":"CD004961","article-title":"Intramedullary nails for extracapsular hip fractures in adults","author":"Queally","year":"2014","journal-title":"Cochrane Database Syst Rev."},{"key":"bib5-20230720","doi-asserted-by":"crossref","first-page":"146","DOI":"10.1097\/00003086-199602000-00020","article-title":"Multicenter trail of modified gamma nail in East Asia","volume":"323","author":"Leung","year":"1996","journal-title":"Clin Orthop."},{"issue":"5-6","key":"bib6-20230720","doi-asserted-by":"crossref","first-page":"337","DOI":"10.1016\/S0020-1383(97)00035-1","article-title":"Failure of femoral head fixation: a cadaveric analysis of lag screw cut-out with the gamma locking nail and AO dynamic hip screw","volume":"28","author":"Haynes","year":"1997","journal-title":"Injury."},{"issue":"6","key":"bib7-20230720","first-page":"242","article-title":"The Gamma Nail in per- and intertrochanteric femoral fractures\u2014alternative or supplement to the dynamic hip screw?
