Evans (1949) analyzed 148 patients across three treatment groups to determine whether routine surgical fixation of trochanteric fractures was justified. The paper proposed a stability-based fracture classification grounded in the integrity of the medial cortical buttress at the calcar femorale. It remains the foundational classification for intertrochanteric fractures and the philosophical basis for modern hip fracture surgery.
The question Evans answered in 1949 — should we operate on frail elderly patients with hip fractures?. Now seems obvious. It was not obvious then. Conservative treatment (traction in a Thomas splint for 15 weeks) was the standard, and a mortality rate of one in five was considered nearly inevitable.
This paper established that immobility, not the fracture itself, was killing patients. Bedsores, pneumonia, and mental deterioration from weeks of enforced traction were the deciding factors. Surgery eliminated that immobility.
Evans' core principle translates directly to modern practice: when you see a trochanteric fracture in an 85-year-old with multiple comorbidities, the frailty is a reason to operate urgently, not to defer. The oldest, most feeble patients have the most to lose from prolonged bed rest.
The classification he proposed. Stability determined by the medial cortical buttress, not fracture level. Is why we assess the calcar on every preoperative hip fracture film today. It is also why medialization of the shaft fragment and calcar reduction remain critical steps in sliding hip screw fixation: an unreduced medial cortex predicts varus collapse whether you use a nail or traction.
