Dear Sir Can you please tell what you mean by Leg Drop ? Is that Foot Drop

Hello. You take him to an orthopaedic doctor.

Hello there. I can understand your concern. You need to take him to a orthopedic surgeon for further evaluation and management. In leg drop there is a apparent shortening of the limb. But i can not suggest you anything on this platform. So its better to get a orthopedician's advice and do what he says. Best regards. Dr. Anil kumar jain. Bangalore.
