The term muscular ossification refers to abnormal deposits of calcium salts within the muscle, causing this part of the muscle and tendon to gradually turn into a hard tissue like bone. Patients can simply interpret this disease as a condition in which the muscle becomes bone. Muscle ossification is also known clinically as injury ossification, which is often caused by severe local trauma, infection, or inflammation, followed by abnormal deposits of calcium salts inside the muscle, which over time can cause the muscle to lose its original function and become a very hard structure. Patients with this condition often experience very pronounced localized pain, decreased muscle strength, and a significant decrease in joint mobility. This condition is most commonly seen around the elbow joint and can have a significant impact on the patient’s daily functional recovery and future life. Prevention is the main focus of this disease, which means that the injury should be treated promptly after it occurs. In addition, after proper treatment, patients need to do functional exercises under the guidance of a doctor to prevent such complications.
