Subtrochanteric fractures of femur can be treated by all of the following methods except:
**Core Concept**
Subtrochanteric fractures of the femur involve breaks below the lesser trochanter, which requires specific treatment due to the area's proximity to vital structures and the difficulty in achieving stable fixation. The goal of treatment is to restore the normal anatomy and function of the hip joint.
**Why the Correct Answer is Right**
The treatment of subtrochanteric fractures involves various methods, including intramedullary nailing, plating, and external fixation. Intramedullary nailing is a popular method due to its ability to provide stable fixation and promote early mobilization. Plating involves the use of screws and plates to stabilize the fracture, while external fixation uses pins and frames outside the body to hold the bone in place.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it is a valid treatment method for subtrochanteric fractures.
**Option B:** This option is incorrect as it is a valid treatment method for subtrochanteric fractures.
**Option C:** This option is incorrect as it is a valid treatment method for subtrochanteric fractures.
**Clinical Pearl / High-Yield Fact**
One key aspect to remember when treating subtrochanteric fractures is to ensure proper alignment and fixation to prevent complications such as malunion, nonunion, and avascular necrosis.
**Correct Answer:** D.
