Fixation of femoral neck fractures Comparison of the Uppsala and von Bahr screws

Internal fixation of femoral neck fractures

“…Among the patients treated with Gouffon screws, 25/38 developed complications. This complication rate was unusually high for multiple pinning (Kofoed and Alberts 1980, Hoeg et al 1982, Stromqvist et al 1984, Madsen et al 1987, Husby et al 1989, Lindequist et al 1989, Rehnberg and Olerud 1989a. Poor reduction (1 1/38) (Kofoed and Alberts 1980, Hoeg et al 1982, Frandsen 1986, and, to a lesser degree, poor positioning of the screws (6/38) (Frandsen 1986, Skinner and Powles 1986, Rehnberg and Olerud 1989a could be important factors.…”

Apart from difficulties in deciding the appropriate length of the Gouffon screws intraoperatively, the method does not seem to involve any technical difficulties (Lindequist et al 1989), but in the process of exchanging a Gouffon screw the trabecular bone in the femoral head may be damaged, thus impairing the ultimate fixation, and thereby increasing the risk of complications (Frandsen 1986, Rehnberg andOlerud 1989b).…”

Osteosíntesis con tornillos canulados en fracturas mediales de cadera. Factores pronósticos y resultados en 93 casos

“…18,19 esta se ha asociado a mayores índices de malos resultados. Una cortical del cuello femoral conminuta es inherentemente inestable, por lo que genera mayor índice de desplazamiento secundario, a pesar de haberse logrado una reducción anatómica.…”

Internally fixed femoral neck fractures: Early prediction of failure in 203 elderly patients with displaced fractures

“…The fixation implants were either a Richards sliding screw plate (SSP) supplemented with a proximal, parallel A 0 6.5 mm cancellous screw or two parallel Olmed hip screws (Rehnberg and Olerud 1989). All patients were operated on within 3 days of injury.…”

“…Internal fixation of displaced femoral neck fracture in the elderly remains a widely used treatment. Although failures resulting in secondary prosthesis replacement are frequent, the method has yielded satisfactory overall results in large series of patients (Barnes et al 1976, Stappaerts 1985, Nilsson et al 1988, 1993, Rehnberg and Olerud 1989. The alternative-primary prosthesis replacement-is also associated with complications (Skinner et al 1989, Parker 1992) and costs more (SGreide et al 1980, Rodriguez et al 1987.…”
