- Discussion:
- Medial cortical overlap technique;
- Kaufer H, et. al. (1974);
- Stover, et al. (1971)
- For unstable intertroch frxs w/ sl medial or posterior instability;
- Reduction w/o medical cortical apposition or overlap is unstable & will result in femoral neck shortening and varus displacement.
- if mod-severe instability is present, must consider osteotomy;
- Stable fixation of intertrochanteric fractures.
- Open reduction of trochanteric fracture.
- Technique:
- shaft of femur is displaced lateral to medial cortex of femoral neck thereby creating a butressing force to resist varus displacement;
- proximal frag is medially displaced to create medial cortical overlap that resists femoral neck shortening and varus displacement
