Most common complication of intertrochanteric fracture femur is:

Malunion. ***Malunion*** - **Malunion** is the most common complication of intertrochanteric fractures, particularly with unstable fracture patterns or inadequate reduction and fixation. - This typically results in leg length discrepancy, gait disturbance, and persistent pain due to abnormal alignment. *Nerve injury* - **Nerve injury** is a rare complication of intertrochanteric fractures, as the major nerves (e.g., sciatic, femoral) are not in close proximity to the fracture site. - While possible with severe trauma or surgical errors, it is not considered the most common complication. *Osteoarthritis* - **Osteoarthritis** can develop years after an intertrochanteric fracture due to altered biomechanics, but it is a long-term sequela, not an immediate or most common post-fracture complication. - Early complications like malunion or infection are more prevalent. *Non-union* - **Non-union** is relatively uncommon in intertrochanteric fractures because this area of the femur has an excellent blood supply, which promotes healing. - This complication is more frequently seen in femoral neck fractures due to their tenuous blood supply.
