Osteosynthesis aids for the treatment of subtrochanteric fractures and / or pertrochanteric fractures and / or femoral neck fractures

摘要

The invention relates to an osteosynthesis aid (10) for the intramedullary treatment of subtrochanteric fractures and / or pertrochanteric fractures and / or femoral neck fractures, comprising a femoral nail (20) insertable into the medullary cavity of a femur, having a distal portion (21) and a proximal portion (FIG. 22) having an obliquely to the longitudinal axis (L) of the Femurnagels (20) extending through hole (25) having a lateral inlet end (26), a medial outlet end (27) and a passage wall (28), wherein in the through hole (25) a force carrier (30) can be used. According to the invention, the lateral inlet end (26) has a chamfer (40) in full, such that a chamfer surface (41) oriented towards the passage wall (28) is formed.
