What could prevent me from bending my elbow all the way?

There are several reasons why your elbow may be difficult to bend completely. A common cause is a previous injury that results in scar tissue or bone changes. After an elbow injury, the healing process may create excess tissue (scar tissue) or additional bone formation, making the joint stiff. This condition is known as post-traumatic stiffness. After an injury, the joint capsule (the soft tissue surrounding the joint) or the nearby muscles and tendons may tighten. This could also restrict the elbow's range of motion. These changes reduce the joint's normal movement space, leading to stiffness. Arthritis in the elbow can also limit flexibility by causing pain and swelling. If you cannot fully bend your elbow, you can start by taking a free symptom checker assessment to better understand what might be causing your limited range of motion before consulting a doctor who can provide a thorough evaluation and recommend appropriate treatment options.
