Because the distal medulla of the femur is wider than the middle diaphysis and intramedullary nails cannot completely fill the intramedullary canal, intramedullary nailing of distal femoral fractures can be difficult when trying to obtain adequate reduction. Some different methods exist for achieving reduction. The purpose of this study was determine whether the use of blocking screws resolves varus or valgus and translation and recurvatum deformities, which can be encountered in antegrade and retrograde intramedullary nailing.<\/jats:p>\n          <jats:p>Thirty-four patients with distal femoral fractures underwent intramedullary nailing between January 2005 and June 2011. Fifteen patients treated by intramedullary nailing and blocking screws were included in the study. Six patients had distal diaphyseal fractures and 9 had distal diaphyseo-metaphyseal fractures. Antegrade nailing was performed in 7 patients and retrograde nailing was performed in 8. Reduction during surgery and union during follow-up were achieved in all patients with no significant complications. Mean follow-up was 26.6 months. Mean time to union was 12.6 weeks. The main purpose of using blocking screws is to achieve reduction, but they are also useful for maintaining permanent reduction. When inserting blocking screws, the screws must be placed 1 to 3 cm away from the fracture line to avoid from propagation of the fracture. When applied properly and in an adequate way, blocking screws provide an efficient solution for deformities encountered during intramedullary nailing of distal femur fractures.<\/jats:p>","DOI":"10.3928\/01477447-20130624-26","type":"journal-article","created":{"date-parts":[[2013,7,4]],"date-time":"2013-07-04T05:44:43Z","timestamp":1372916683000},"source":"Crossref","is-referenced-by-count":21,"title":["Blocking Screws for the Treatment of Distal Femur Fractures"],"prefix":"10.3928","volume":"36","author":[{"given":"Mustafa","family":"Seyhan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Selami","family":"Cakmak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ferdi","family":"Donmez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arel","family":"Gereli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2308","reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/TA.0b013e31815edeb8"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s004020050320"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-200409000-00004"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-200103000-00003"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-199308000-00001"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/BOT.0b013e3181ad61f2"},{"key":"e_1_3_1_8_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200412002-00004"},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-200605000-00013"},{"key":"e_1_3_1_10_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-199911000-00006"},{"key":"e_1_3_1_11_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.81B6.10000"},{"issue":"2","key":"e_1_3_1_12_2","first-page":"136","article-title":"Technique for precise placement of Poller screws with intramedullary nailing of metaphyseal fractures of the femur and the tibia","volume":"42","author":"Shahulhameed A","year":"2011","unstructured":"Shahulhameed A, Roberts CS, Ojike NI.
