Between April 1999 and April 2004, 3497 Birmingham hips were
inserted by 89 surgeons. Fracture of the neck of the femur
occurred in 50 patients, an incidence of 1.46%. Complete
data were available for 45 patients in whom the incidence
was 1.91% for women and 0.98% for men. The relative risk of
fracture for women vs men was 1.94961 and this was
statistically significant (p < 0.01).The mean time to
fracture was 15.4 weeks. In women the fractures occurred at
a mean of 18.5 weeks and were more likely to have been
preceded by a prodromal phase of pain and limping. In men
the mean time to fracture was 13.5 weeks. Significant varus
placement of the femoral component, intra-operative notching
of the femoral neck and technical problems were common
factors in 85% of cases.
