Subtrochanteric section Middle section Distal section

These are simple fractures of the femoral diaphysis, with a spiral fracture line, located at its proximal third (subtrochanteric; A1.1), middle third (A1.2) or distal third (A1.3). Ref. Manual of Internal Fixation:
254 - 265. 270 - 281. 232 - 251.

Because of their long and broad fracture surface, a very effective interfragmentary compression with lag screws can be obtained when the fracture is anatomically reduced. The high friction force between both fragments will make the bone participate very actively in its own stability. On the other hand, when the reduction is not anatomic interfragmentary compression is at great risk, because of its spot load concentration (instead of broad surface load distribution), and can result in iatrogenic fractures.

Different plates, with a protection (neutralization) effect, can be used depending on the site of the fracture. The lag screws can either be placed through the plate or independently. The proximal and distal third fractures are better stabilized with the 95º condylar blade plates. The DCS is a good alternative for osteoporotic bone.
