![]() Type C: Complex fractures of both the proximal radius and ulna.Type B: Intra-articular fractures of either the radius or ulna.Type A: Extra-articular fractures of the metadiaphysis of either the radius or the ulna.This classification incorporates all fractures of the proximal ulna and radius into one group, subdivided into three patterns: It also may be either non-comminuted (Type IIIA) or comminuted (Type IIIB). Type III: Displaced unstable fracture – In this case, the fracture fragments are displaced and the forearm is unstable in relation to the humerus. ![]() It can be either non-comminuted ones (Type IIA) or comminuted (Type IIB). ![]() That is why there is no elbow instability. Type II: Displaced, stable fractures – In this pattern, the proximal fracture fragment is displaced more than 3 mm, but the collateral ligaments are intact.Type I: Non-displaced fracture – It can be either non-comminuted ones (Type IA) or comminuted (Type IB).It is composed of three types, and each type is divided in two subtypes: subtype A (non-comminuted) and subtype B (comminuted). There are several classifications that describe different forms of olecranon fractures, yet none of them have gained widespread acceptance: Mayo classification īased on the stability, the displacement and the comminution of the fracture. A true lateral x-ray is essential to determine the fracture pattern, degree of displacement, comminution, and the degree of articular involvement. Frontal and lateral X-ray views of the elbow are typically done to investigate the possibility of an olecranon fracture. Then a complete neurological exam of the upper limb should be documented. To assess an olecranon fracture, a careful skin exam is performed to ensure there is no open fracture. Powerful pull of the triceps muscle can also cause avulsion fractures. Indirect trauma: by falling and landing with an outstretched arm. Trauma to the elbow often results in comminuted fractures of the olecranon. ĭirect trauma: This can happen in a fall with landing on the elbow or by being hit by a solid object. "Side-swipe" injury when driving a motor vehicle with an elbow projecting outside the vehicle resting on an open window's edge is an example. motor vehicle accidents), and due to falls when the triceps are contracted. Typically they are caused by direct blows to the elbow (e.g. Examination can bring out a palpable defect at the site of the fracture. Due to the proximity of the olecranon to the ulnar nerve, the injury and swelling may cause numbness and tingling at the fourth and fifth fingers. Swelling over the bone site is seen and an inability to straighten the elbow is common. People with olecranon fractures present with intense elbow pain after a direct blow or fall. 4.2.2 Intramedullary fixation and plates.James Mazzara, orthopedic elbow surgeon, treating patients in Manchester, South Windsor, Enfield, Glastonbury and surrounding Hartford communities. Often surgical pins and a tension band may be used.įor more information on olecranon fractures or how to treat a broken elbow, please contact the offices of Dr. Mazzara may use a bone graft if needed he may also remove tiny fragments of bone that would not heal properly. This procedure is sometimes called an ORIF or Open Reduction and Internal Fixation and involves realigning the bone fragments to their correct anatomical position. Mazzara may perform an olecranon fracture fixation. The goal of olecranon surgery is to place the pieces of elbow back into the proper position and to keep them in place for proper healing. Large, displaced or open (when the bone punctures through the skin) elbow fractures require surgery. A splint is typically worn for 3 to 6-weeks and physical therapy is recommended after the bone has healed. Frequent x-rays will be necessary to ensure the bones are healing in the proper position. Mazzara may recommend a sling or a splint to keep the elbow in place while it heals. Fractures that are in place may be treated non-surgically.įor elbow fractures that are not displaced, Dr. If the bones are displaced and if there is joint involvement, surgery may be necessary. The treatment for an olecranon fracture will depend greatly on the severity of the break. What is the treatment for a broken elbow or an olecranon fracture?
