| Abstract |
This is a prospective comparative clinical and experimental study re-garding the surgical management of peritrochanteric femoral fractures, us-ing two different osteosynthetic devices that is the sliding screw-plate and the Bousquet nail-plate. The study commenced three years ago in January 1991. Internal osteosynthesis was performed in 152 patients. Hundred and ten patients were followed up at least for six months. The follow up pe-riod varied from six to sixteen months. Out of 110 patients with peritro-chanteric fractures stable fractures were encountered in thirty-seven pa-tients and unstable in seventy-three. Fifty-eight patients underwent fixa-tion with the sliding screw-plate and fifty two patients with the Bousquet nail-plate. The postoperative management was the same for both groups inde-pendently from the type of the implant used. Evaluation of the parametres blood loss during the operation, opera-tive time, hospitalization time and cost revealed no significant differ-ences between the two groups of patients. The mobility and the ability for self care prior the fracture and six months postoperatively were compared. The changes observed were not significant different between the two groups. Migration of the implant and varus deformation of the neck shaft an-gle were assessed by AP X-rays. Regarding the varus deformation of the neck-shaft angle, in unstable fractures, the sliding screw was superior but the difference was not significant. Regarding the migration in unsta-ble fractures, the sliding screw was superior and this was statistically signifi-cant when the implant was centrally placed. Experimentally produced stable and unstable trochanteric fractures in cadaveric femurs were fixed with both implants and consequently loaded. The results obtained confirm the clinical results. In stable fractures reduction and restoration of bone continuity is ef-fected, decreasing the mechanical demands from the implant. Under these circumstances both systems are adequate. In unstable fractures the sliding screw allows backward shift, pro-ducing apposition at the fracture site increasing stability of fixation. Placement of the screw should be central within the femoral head, since eccentric placement produces rotational instability around the implant, re-sulting in displacement of the fracture. Rotation of the head and neck around the implant is better checked by the triflanged Bousquet nail but lack of the sliding mechanism does not allow apposition of the fragments, increasing the mechanical de-mands from the implant. In unstable fractures the sliding screw appears to be signifi-cantly superior it should however be centrally placed.
