Subchondral screw fixation for femoral neck fractures

Abstract

We describe a method of internal fixation for femoral neck fractures which has been newly developed to reduce the frequency of early complications. Two cannulated screws are inserted in the axis of the femoral neck to reach into the subchondral bone of the femoral head. The screws are inserted over guide pins and the tip of the screw is self-tapping and designed to provide good anchorage in the femoral head. We used this method in 44 consecutive patients in a prospective study with no exclusions, followed for a minimum of 24 months. All fractures healed within 12 months, and there were no cases of early loosening or nonunion.In four cases, late segmental collapse had developed during the mean follow-up period of3O months.

Quality of Life and Femoral Neck Fractures

“…This resulted in a mean age of 80 in Studies I-V, which is slightly higher than in most studies on patients with femoral neck fractures (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17) due to the exclusion of younger and middle-aged patients. The higher age, mean 83, in Study 6 reflects the inclusion criteria selecting lean /malnourished (BMI <24 kg/m 2 ) women with a higher frequency of comorbidity.…”

“…Optimising the treatment for improved outcome and a reduced need for secondary surgery is therefore mandatory. In many studies on hip fractures, the outcome of treatment has been defined in terms of complications or specific hip scores (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17). Quality of life as an outcome measure is rarely used.…”

Decrease in bone mineral density and muscle mass after femoral neck fracture: A quantitative computed tomography study in 25 patients

“…They had had no previous hormonal therapy, other medications or illnesses known to affect bone metabolism. The patients were operated on within 2 days of the fracture with closed reduction and osteosynthesis using 2 parallel Olmed screws (Rehnberg and Olerud 1989). All patients were mobilized on the day after the operation, under the supervision of a physiotherapist, with full weight-bearing on the operated leg.…”

Femoral neck fracture fixation with hook-pins

“…It seems very important to use osteosynthesis exerting little trauma to the femoral head vascularization (Rehnberg and Olerud 1989). According to tetracycline studies (Stromqvist and Hansson 1983), virtually every femoral head has some degree of reduced viability after femoral neck fracture.…”
