Thirty patients with Garden's type I and II femoral neck fracture treated byKadar's spongiosa compressive screws were retrospectively studied. The mean age of patientswas 70±9 years. In all cases, the etiology was a casual accident. Fracture reduction and positioningof the osteosynthesis were assessed by radiographic criteria. Satisfactory reduction wasachieved in 93 percent of the patients, and the osteosynthesis was accurate in 50 per cent. Asfor complications, there were 2 early fracture redisplacement. There were neither non-unionnor avascular necrosis. When evaluating functional results according to Merle d'Aubigné criteria,satisfactory results were found in 84 per cent of patients. In our opinion, the more importantpronostic factor is the anatomic reduction of the fracture.
