What is a coronoid fracture?
Coronoid fracture is an interruption of the coronoid process of the ulna, a small, triangular part of the bone that protrudes out from the upper front of the ulna. The ulna is the inner of two long bones located in the forearms, on the other side of the thumb. Coronoid fractures rarely occur without any other fracture on the ulna or elbow dislocation. The falls in which the arms are stretched are the most common causes of coronoid fractures.
The coronoid process plays an important role in the stabilization of the elbow. Several different arm bonds, including brachialis, are connected to the coronoid, the muscle at the top of the arm, which allows the elbow bending. Collateral bonds and several flexor tendons are also connected to the coronoid process. Coronoid fracture can reduce the stability of the elbow and make it difficult to move the forearm.
Symptoms of coronoid fractures include pain and swelling in the elbow. Depending on the severity of thzlomenin, bending and elbow expansion can be difficult or impossible. In addition to X -ray to determine the scope of brokenNY is required complete neurovascular test to measure nerve function and blood flow in the area. A computer axial tomography or CT scan can be performed to provide more anatomical details concerning fracture details.
Coronoid factor treatment depends on the type and severity of the break. In cases where a fracture includes less than 50 percent of the coronoid process, it is possible to interrupt without surgery. Early mobilization is usually preferred, while the patient regained a certain range of movement during the first month after the break to prevent stiffness.
Coronoid fractures, including more than 50 percent of the process, usually require surgery to repair damage internally. In some cases, part of the Radial High -High Head or Olecranon - Physical Eminence Behind the elbow - can be used to rebuild the coronoid process. Surgeon can use metal screws to sTabilization of the elbow and help the coronoid process heal.
After the treatment of coronoid fracture, aftercare focuses on both maintaining the overall stability of the elbow and the scope of movement. During each recovery phase, X -rays are used to determine the effectiveness of treatment and whether the bones are heal properly. Physical therapy may be required to help regain as much movement as possible.
long -term complications include a decrease in the range of movement, osteoarthritis and continued pain. Paresthesia, a sense of numbness, armor or prick in the skin is also a possible long -term complication. Younger patients have a lower risk of complications than older patients.
