Fixation of femoral neck fractures by AO cancellous screws

ABSTRACT

In this paper we report a series of 38 femoral neck fractures that were treated by closed reduction and internal fixation with multiple AO cancellous screws. At a mean follow up of 29.8 months, the results were satisfactory in 28 patients [73.7%] and unsatisfactory in 10 patients [26.3%]. Complications included non-union in 4 cases [10.5%], avascular necrosis in 5 cases [13.2%] and segmental collapse in one case [2.6%]. We concluded that osteosynthesis of femoral neck fractures with AO cancellous screws is an easy procedure that affords rigid fixation and relatively low incidence of complications and at the same time utilizes cheap implants and demands an average level of training. While better results were obtained in undisplaced fractures [Garden Stage I and II], and in fractures with good quality of postoperative reduction, age did not appear to be an important factor in outcome:
