My daughter has a hard immoveable lump on her thigh, she is 12 weeks post op from an internal fixation of her distal femur....the bump is not near a screw or the plate. The physical therapist says it is in the muscle....what could it be, should we be concerened?
Hi, If I were your treating Doctor for this case, I would consider only one possibility that is myositis ossifies... Myositis ossifies develops some time after a contusion or blow to a muscle usually in the thigh. Symptoms of Myositis ossifies include pain in the muscle particularly during exercise.  An X-ray can confirm the diagnosis and show bone growth; sometimes biopsy needed! An X-ray of the muscle can be done to see when it is safe to start rehabilitation and strengthening exercises. In particularly severe cases surgery can be performed to remove the bone growth. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
