From: Geriatric trauma hip fractures: is there a difference in outcomes based on fracture patterns?
Major classes of femur fractures (A) and categories of femur fracture types (B). A. Femur fracture classes: (a) Femoral neck and (b) All trochanteric fractures. Red lines indicate fracture locations, as indicated by arrows. B. Femur Fracture Patterns: (a) Femoral neck (b) Intertrochanteric (c) Subtrochanteric (d) Greater trochanter (e) Combined inter & subtrochanteric. Red lines indicate fracture location, as indicated by arrows. For purposes of statistical analysis, patients with fractures corresponding to figures (c), (d), and (e) were grouped as "other". However, such grouping may not represent homogenous clinical category.
