Resumen (ES)
We present a series of 164 trochanteric fractures
treated with the dynamic hip screw, evaluating fracture type
according to the AO classification, osteoporosis index,
cephalic screw placement and quality of reduction, to relate
them with the sliding of the cephalic screw and the appearance
of complications. The more frequent fracture types
were A.1.1. and A.2.1. with a 42.6%. 72.6% of patients were a
4, 5 or 6 osteoporosis index, in 91.4% of cases the screw position
was sintable and in 64% of cases de quality of assembly
was anatomical.The greatest cephalic screw sliding and the
highest rate of complications happened in unstable fractures,
in the 4 and 6 osteoporosis index, in cases of unsintable
screw placement and when the reduction quality was inadequate.
