Popis:	In Sects. 1.3 and 1.5, we have discussed the anatomical and biomechanical characteristics of the proximal femur that determine the optimal position of the stabilizing implants during internal fixation (three-point buttressing: lateral cortex, Adam’s arch/calcar femorale and subchondral bone in the femoral head). In Sect. 4.2.2, we summarized the fundamental biomechanical principles as they are related to the design of the implant in respect to the internal fixation with two Smith-Petersen nails. These principles are still valid: — Necessity of two or more implants; — Protection against tilting in varus and rotation of the femoral head; — Allowing settling of the fracture.
