Initiation of therapy causes soreness for many patients.įracture healing requires 8-12 weeks and many patients require months of therapy to reach maximum improvement. Patients report pain after surgery, but the pain generally improves as the fracture fragments are stabilized. Bracing may be used in the postoperative period to control motion and formal therapy is often a useful adjuvant for care. The ability to gain stable fixation determines the amount of motion allowed for the elbow, as well as the postoperative timing. Lateral view of an olecranon fracture treated with a tension band techniqueĪ lateral view of an olecranon fracture treated with application of plates and screws RehabilitationĪfter surgery the arm is immobilized in a splint to allow for wound healing. However, complicated injuries requiring Extensive dissection to identify nerves, fracture fragments and any ligamentous injuries usually makes these procedures done in a hospital setting. Most isolated injuries can be performed as an outpatient surgery. However, the most common technique for isolated olecranon fractures is the application of pins and wires (tension band repair). Extensile incisions may be required to place plates and screws in position. The anesthesia choices include regional or general anesthesia. These fractures are typically complex and require specialized care. Typically, better alignment is associated with better function. The cartilage surfaces are the gliding mechanism by which the elbow moves. The goals of operative treatment is to alignment the fracture and the cartilage surfaces. Operativeĭisplaced fractures typically require operative management. With a fracture as seen above, this fragment is pulled proximally by the unopposed pull of the triceps. The triceps muscle (in red) inserts into the olecranon. Stiffness is problematic with elbow fractures in general and may be more pronounced with longer immobilization. Nonoperative management usually requires some period of immobilization, followed by supervised range of motion. Immobilization in extension is typically performed when this is contemplated. ![]() Since the triceps mechanism inserts into the olecranon, most of these fractures displace or have a tendency toward displacement. Nonoperative treatment is reserved for nondisplaced fractures currently. If more concern is directed toward ligament or tendon injury, MRI imaging may be ordered.Ī three dimensional CT scan of a comminuted (many pieces) olecranon fracture left image. However, additional imaging for bone, such as computerized tomography (CT scan) may yield additional helpful information. In many cases, x-rays alone may adequately provide enough information to determine treatment. Lateral views showing a normal elbow on the left and a fracture of the olecranon process of the ulna on the right. X-rays may be taken from several angles to better delineate the fracture. X-rays are indicated to determine the bones which have been injured and if there are any dislocations associated with the injury. Similarly, nerve function may be disrupted due to trauma or displacement of fractures. Although uncommon, fractures in this area may embarrass vascular supply secondary to injury or swelling. Similarly the sensation and motion of digits are noted. The status of the vascular supply to the hand is observed. Physician ExamĪfter taking a history and noting your symptoms, a physical exam is then performed by the surgeon. There may be deformity of the arm dependent upon the degree of displacement of the fracture. Patients who experience olecranon fractures present with pain, swelling and often bruising over time. Ligaments of the elbow viewed from the lateral aspect Diagnosis Symptoms As we age, the strength of both ligaments and bones decrease over time. The bones of the elbow are held together by joint capsule, ligaments and tendons. The biceps inserts into the radius and bends the elbow. ![]() The triceps muscle inserts into the olecranon process of the elbow and straightens the elbow. The olecranon is the tip of the ulna and serves as the insertion point for the triceps muscle-which straightens the elbow. Lateral view of a right elbow demonstrating humerus, ulna, and radius (arrow pointing toward olecranon process of the ulna). The elbow utilizes three bones in articulation to accomplish these purposes-humerus, ulna, and radius. The elbow serves two distinct functions: 1) to bend and straighten 2) to turn the palm up and palm down. While many elbow fractures in children can be treated nonoperatively, the majority of fractures in adults will require surgery Anatomy ![]() These injuries interfere with the ability of the elbow to place the hand in a functional position.
