“…Of the moderately displaced fractures there were 9 reoperations due to femoral head necrosis, 11 due to local pain, 2 due to loss of position of implant without fracture displacement, 1 due to new fracture around the implant, and 9 due to infection and hematoma. Parameters thought to be associated with risk of reoperation (Alberts and Jervaeus 1990, Nilsson et al 1993, Kaehrle et al 2001) were entered into a logistic regression model, but only fracture type had a significant influence on risk of reoperation ( Figure 1) by a factor of 2.4 (1.5-3.8).…”
