Which characteristic defines a stable intertrochanteric fracture?

A stable intertrochanteric fracture is characterized primarily by an intact posteromedial cortex and the absence of significant displacement or malalignment. The intertrochanteric region is critical for the stability of the hip joint, and when the posteromedial cortex remains intact, it indicates that the tension and load-bearing have not been significantly compromised, allowing for better healing and rehabilitation outcomes.

The reference to the base of the femoral neck being stable does not directly pertain to intertrochanteric fractures, as these are defined more closely by their location in relation to the trochanters rather than the neck itself. The most critical factor for stability in intertrochanteric fractures is maintaining the integrity of the posterior structure, which supports the anatomy and biomechanics of the hip properly.

In conclusion, both an intact posteromedial cortex and the consideration of base stability contribute to defining a stable intertrochanteric fracture. This highlights the importance of ensuring that both factors are considered in assessing the overall stability and treatment plan for such injuries.
