When is surgical excision indicated for myositis ossificans?

Surgical excision for myositis ossificans is indicated when the lesions become mature and start causing symptoms. Myositis ossificans is characterized by the abnormal formation of bone tissue in muscles or soft tissues following trauma. In the early phase following an injury, the condition often resolves spontaneously without surgical intervention, especially if it is asymptomatic.

Maturity of the lesion suggests it has completed its development and is less likely to reabsorb. If the patient experiences symptoms such as pain, loss of range of motion, or functional limitations due to the ossification, surgical intervention is warranted to alleviate these symptoms and improve function. Waiting until the lesion has matured ensures that the procedure is performed at the appropriate time, minimizing the risk of complications and allowing for optimal recovery.

The other options do not appropriately reflect the clinical reasoning for surgical intervention. For instance, immediate surgery after diagnosis may lead to unnecessary complications, as the lesion often resolves on its own. Timing surgery too early, before maturity, might increase the risk of incomplete removal and recurrence. Furthermore, surgical excision is not limited to athletes; it applies to any patient exhibiting symptomatic lesions regardless of athletic status. Thus, maturity and symptomatology are crucial factors guiding the decision to proceed with surgery.
