Fixation of femoral neck fractures by AO cancellous screws

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

Intra-articular aprotinin versus steroids in osteoarthritis of the knee

The results of intra-articular Injection of aprotinin and corticosteroids have been assessed by a double-blind trial design in 32 symptomatic osteoarthritic knees. Aprotinin produced a better and longer-lasting symptomatic relief than steroids. Whereas steroids are used only for symptomatic relief in osteoarthritis, aprotinin may in addition effect a genuine cure of the diseased joint through inhibition of the proteolytic enzymes responsible for carticlage breakdown
