- Discussion:
- Medial cortical overlap technique;
- Kaufer, H. et. al. JBJS. 1974;
- Stover et. al. N.Y.State Med. J. 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;
- 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;
---------------
Biomechanical evaluation of anatomic reduction versus medial displacement
osteotomy in unstable intertrochanteric fractures.
