This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Orthopaedics
The commonest hip injury in the elderly patients is - 
Select and explain. 
A. Stress#, B. Extracapsular #, C. Impacted # neck of femur, D. Subcapital capsular fracture neck of femur
B: Extracapsular #
Answer: B: Extracapsular # 
Explanation: First see statements of different textbooks:-

"The femoral neck is the commonest site of fracture in the elderly".   —Apley's
"Intertrochanteric fracture is four times more common than neck fracture".  —Ebnezar
"More-over fracture intertrochanteric femur occurs in elderly patients even more than fractures of the femoral neck itself". — Watson Jones
"Femoral neck fractures and intertrochanteric fractures occur with about the same frequency".— Campbell

I cannot comment about the commonest fracture among these two.
However, I am sure about the answer as extracapsular fracture includes both extracapsular neck fracture (Basal / Basicervical fracture) and inter-trochanteric fracture. Basal (Basicervical) fracture is the most common type of neck fracture. So, even if neck fracture and IT fracture occur with same frequency, extracapsular fractures (Basal fracture + Intertrochanteric fracture) are more common than intracapsular (transcervical and subcapital) fractures.
