What causes prominent boney lump formation outside the leg?
Patient: My daughter, age 5, has a prominent boney lump on the outside of her leg (at the top of her shin bone). I think there is one on her other leg but not as obvious. She is very slight and her knee joints look big but I put this down to her skinny legs. Are these lumps normal? Doctor: Hello,  It could be an osteoma. However other causes must be ruled out. Consult an orthopaedic and get evaluated. An X-ray is required for further assessment.  Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr. Shinas Hussain, General & Family Physician
