The comparison of femoral curves and curves of contemporary intramedullary nails

Abstract

The difference between the curves of femur and the contemporary femoral nails implicates the inadequacy of the design of such nails for the Caucasian race living in Anatolia. Therefore, such nails should be revised accordingly to prevent the above-mentioned complications.

The digital measurements for femoral prosthesis in a Turkish population

“…The nail may rip the distal anterior cortex of the femur during femoral nailing. [1,18,22] Additionally, mismatch of the nail, curve of the femur cause inadequate contact of the fracture ends and it leads to new problems. [1,21] The insertion process may become difficult as an inappropriately curved nail leans against the medullary wall.…”

“…[21] In the presences of an uncompensated mismatch between the curve of a femoral nail and the femoral medullary bowing, serious problems may arise. [1] An iatrogenic fracture may develop during femoral nailing. The nail may rip the distal anterior cortex of the femur during femoral nailing.…”

“…[13] On the other hand, intramedullar nailing of femur is important for of diaphyseal femur fracture. [1,[16][17][18] If there is a mismatch between curvature of the intramedullary nails and the anterior bowing of the femur several problems may arise like angular defects, iatrogenic fractures and penetration of the distal anterior femoral cortical bone. [1,16] Several basic and clinical studies were conducted to determine the compatibility of femoral medulla with intramedullary nails because intramedullary nailing is currently accepted as the gold standard in the treatment of diaphyseal femur fractures.…”

“…[1][2][3] Some clinical studies explained these variations [1,3,4] and several studies concerning the anatomy and functional axes of femur have previously been made on normal femur. [5][6][7][8][9][10][11] For intraoperative referencing, several anatomical landmarks concerning femur are used by surgeons.…”

“…[1,16] Several basic and clinical studies were conducted to determine the compatibility of femoral medulla with intramedullary nails because intramedullary nailing is currently accepted as the gold standard in the treatment of diaphyseal femur fractures. [1,16] The goal of the present study is (i) to analyses the variation in the angle between anatomical and mechanical axes of the femur and to determine the safety degrees of distal femoral valgus cut for a routine surgical procedures, (ii) to evaluate shaft curve of the femur according to anatomical axis of femur and to compare with curve of the femoral nail in used in Turkish population.…”
