What is a significant risk of prolonged surgical intervention for Fibrous Dysplasia?

1. Malignant transformation

2. Fracture of affected bone

3. Infection

4. Non-union of bone

The correct answer is: Fracture of affected bone

Prolonged surgical intervention for Fibrous Dysplasia presents a significant risk of fracture of the affected bone. This is primarily due to the nature of Fibrous Dysplasia, which involves the abnormal development of bone. The affected bone tissue is less dense and mechanically weaker compared to normal bone, making it more susceptible to fractures, especially after extended surgical manipulation or prolonged exposure during surgical procedures. When surgical interventions take longer than anticipated, the risk increases as the bone's structural integrity can be further compromised. In addition, the process of surgery itself may affect the surrounding tissues and impact the overall stability of the affected area, leading to an elevated risk of fractures during recovery and rehabilitation. Other concerns such as malignant transformation, infection, and non-union can also be risks associated with surgical procedures, but the direct consequence of extended surgery on the underlying bone biology makes fracture a particularly significant concern in the context of Fibrous Dysplasia. This condition's unique characteristics necessitate careful consideration of bone integrity during any surgical management, highlighting the importance of anticipating this risk in surgical planning and execution.
