By changing from a distal to a proximal osteotomy for lengthening, the mean range of knee movement was significantly increased from 98.1\u00b0 to 124.2\u00b0 (p = 0.041) and there was a trend towards a reduced requirement for quadricepsplasty, although this was not statistically significant (p = 0.07). The overall incidence of regenerate deformation or fracture requiring open reduction and internal fixation was similar in the distal and proximal osteotomy groups (56.7% and 53.8%, respectively). However, in the proximal osteotomy group, pre-placement of a Rush nail reduced this rate from 100% without a nail to 0% with a nail (p &lt; 0.001). When comparing a distal osteotomy with a proximal one over a Rush nail for lengthening, there was a significant decrease in fracture rate from 58.8% to 0% (p = 0.043). <\/jats:p><jats:p> We recommend that in this group of patients lengthening of the femur with an Ilizarov construct be carried out through a proximal osteotomy over a Rush nail. Lengthening should also be limited to a maximum of 6 cm during one treatment, or 20% of the original length of the femur, in order to reduce the risk of complications. <\/jats:p>","DOI":"10.1302\/0301-620x.91b7.21304","type":"journal-article","created":{"date-parts":[[2009,6,30]],"date-time":"2009-06-30T21:39:10Z","timestamp":1246397950000},"page":"962-967","source":"Crossref","is-referenced-by-count":46,"title":["Lengthening of the congenital short femur using the Ilizarov technique"],"prefix":"10.1302","volume":"91-B","author":[{"given":"W.
