Fig. 6From: The choice of internal fixator for fractures around the femoral trochanter depends on area classificationThe choice of internal fixator for type 3 and type 3–4. When the choice of internal fixator for type 3–4 fractures is compared with that for type 3 fractures, a long nail was chosen in 42.3 % in type 3–4 fractures, whereas a long nail was chosen in only 1 case (0.8 %) in type 3 fractures; this difference is significant (Chi square test; P < 0.0001)Back to article page
