There were 198 fractures evaluated retrospectively and 118 after instruction. <\/jats:p><jats:p> The TAD is the sum of the distance from the tip of the screw to the apex of the femoral head on antero-posterior and lateral views. This decreased from a mean of 25 mm in the control group to 20 mm in the study group (p = 0.0001). The number of mechanical failures by cut-out of the screw from the head decreased from 16 (8%) in the control group at a mean of 13 months to none in the study group at a mean of eight months (p = 0.0015). There were significantly fewer poor reductions in the study group. <\/jats:p><jats:p> Our study confirms the importance of good surgical technique in the treatment of trochanteric fractures and supports the concept of the TAD as a clinically useful way of describing the position of the screw. <\/jats:p>","DOI":"10.1302\/0301-620x.79b6.0790969","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T11:52:54Z","timestamp":1519213974000},"page":"969-971","source":"Crossref","is-referenced-by-count":634,"title":["AWARENESS OF TIP-APEX DISTANCE REDUCES FAILURE OF FIXATION OF TROCHANTERIC FRACTURES OF THE HIP"],"prefix":"10.1302","volume":"79-B","author":[{"given":"M.
