Hi lybrate-user. First thing you should do is to get an x-ray done of your elbow if it is not done yet. Minor chip fracture if undisplaced will heal my simple immobilization of elbow. You may require a brace or a plaster for few weeks. If it is displaced, then you may need a small surgery to fix it. Injection of calcium over elbow has no role in management and is not recommended. These type of injuries are frequently associated with ligament tears. So proper evaluation is advised.
