[{'content': 'The commonest hip injury in the elderly patients is - \nSelect and explain. \nA. Stress#, B. Extracapsular #, C. Impacted # neck of femur, D. Subcapital capsular fracture neck of femur', 'role': 'user'}, {'content': 'Answer: B \nExplanation: First see statements of different textbooks:-\n\n"The femoral neck is the commonest site of fracture in the elderly".\xa0\xa0\xa0—Apley\'s\n"Intertrochanteric fracture is four times more common than neck fracture".\xa0\xa0—Ebnezar\n"More-over fracture intertrochanteric femur occurs in elderly patients even more than fractures of the femoral neck\xa0itself".\xa0— Watson Jones\n"Femoral neck fractures and intertrochanteric fractures occur with about the same frequency".— Campbell\n\nI cannot comment about the commonest fracture among these two.\nHowever, 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.', 'role': 'assistant'}]
