Resumen (ES)
We report a retrospective analysis of the incidence
of osteonecrosis in 233 patients with femoral neck fractures
treated with cancellous screws. The average age was
80,6 years. Seventy-one patients (26%) had a non-displaced
fracture (Garden l-ll) and 172 (74%) had a displaced fracture
(Garden lll-IV). Six months after surgery 170 patients survived
(73%). Thirty-four of them (20%) had developed osteonecrosis
and 10 (5,9%) collapse. After a follow-up of 12 months 114
patients (49%) survived. Twenty-four of these patients (21%)
had an osteonecrosis and 18 (16%) a collapse. Two years
after surgery 103 patients (44%) survived. Seven of them had
developed an osteonecrosis (8%) and 25 a collapse (27%). At
the time of most recent follow-up (three years) 84 patients
survived (36%). There was a collapse in 8 of them (10%). We
observed a significant relation between patients who had a
displaced fracture, a failed reduction, an unstable fixation,
and the later development of necrosis and late collapse.
