Abstract
A prospective, randomized trial of 104 consecutive patients with displaced fractures
of the femoral neck treated with either a sliding screw plate or four AO cancellous
bone screws was performed to study the influence of the fixation device and the fixation
procedure on the vascularity of the femoral head. The vitality of the femoral head
was determined by 99mTc-MDP scintigraphy performed 2–3 months after the operation. Eighty-seven patients
(84 per cent) were available for assessment. The two treatment groups were comparable
with regard to age, degree of primary displacement and quality of reduction. There
were significantly more (P < 0.01) avascular femoral heads or femoral heads with reduced vascularity in the
sliding screw plate group (![Math Eq]()
, 35 per cent) than in the four AO cancellous bone screw group (![Math Eq]()
, 11 per cent).
