What factor can lead to inadequate stabilization from internal fixation in intertrochanteric fractures?

• A. Low blood pressure
• B. High level of activity pre-surgery
• C. Comminution of bone
• D. Excessive weight loss

Answer: (C)

In the context of intertrochanteric fractures, comminution of bone refers to the fracture being fragmented into multiple pieces. This complexity can significantly impact the effectiveness of internal fixation devices. In cases of comminuted fractures, the loss of structural integrity challenges the ability of the fixation system to maintain proper alignment and stabilization of the fractured fragments. When a fracture is comminuted, the area may not provide adequate sites for the fixation devices, such as screws or plates, to anchor effectively, leading to a higher risk of displacement or failure of stabilization. The myriad of fracture fragments can create complications during surgery, as the surgeon must navigate through a less predictable anatomy to achieve proper alignment. As a result, the risks of poor healing or the need for further interventions are heightened in these scenarios. This highlights the importance of evaluating the fracture pattern during pre-operative planning and the selection of appropriate fixation methods, especially for fractures that exhibit a high degree of comminution.
