Our patient had biepicondylar fracture dislocation of the elbow concomitant with complete ulnar nerve … Elbow dislocations are staged depending on the disruption of different stabilizers, such as the ulnohumeral articulation, medial collateral ligament, and lateral collateral ligament. If it is important to evaluate the ligaments, a magnetic resonance image (MRI) can be helpful, however, it is rarely required. associated with complete or near complete circular disruption of capsuloligamentous stabilizers; pathoanatomic cascade . It is also important to check the nerve supply to the hand. 2004;86;975-982. Sometimes, the elbow is only partially dislocated. A complex dislocation has related fractures. The unstable elbow. ... axillary nerve injury; postoperative care. The elbow is a complex joint designed to withstand a wide range of dynamic exertional forces. Reduction: Option #1: Option #2: Lay in prone position with arm hanging over edge. [1][2][3], Typically, elbow dislocation is caused by a traumatic fall onto an outstretched hand resulting in an hyper-extension injury. [1], In adults, they are the second most commonly dislocated joint proceeded by shoulder dislocations. Elbow and forearm injuries. An elbow can be dislocated by landing on it with an outstretched hand. Instability (recurrent instability may indicate a ligamentus repair, Triceps lengthening using Speed's procedure. The vast majority of dislocations are posterior. The radial head and coronoid process are the most commonly fractured structures. - Lateral condyle elbow fracture mechanism of injury - Avulsion of medial epicondyle - "Pusher" techniques for reduction of posterior elbow dislocation - "Puller" technique for reduction of a posterior elbow dislocatio - Radial head subluxation classic arm position - Pronator compression test - Trunks and cords of the brachial plexus Neurovascular injury is uncommon from posterior elbow dislocations. Office Hours: M-F 9:00-5:00. Palpation should help your surgeon check that the equilateral triangle formed by the olecranon and epicondyles is present. [2], Overall the best treatment for PED is initial short term restricted ROM (usually two weeks or less) followed by early mobilisation including PROM, progressing to AROM and functional strengthening. Management of an uncomplicated posterior elbow dislocation. In adults, the elbow is the second most frequently dislocated major joint, after the shoulder. Fractures may exist on the radial head, coronoid process, olecranon, humeral condyles, or capitellum. Complex elbow dislocation consists of both ligamentous and bony injuries. When refering to evidence in academic writing, you should always try to reference the primary (original) source. [] This injury entails disengagement of the coronoid process of the ulna from the trochlea of the humerus with movement posteriorly. [14], Prior to the decision to surgically manage these factors are considered:[14][9]. A dislocated elbow occurs when the radius (or radius head) and/or ulna bones of the forearm are moved out of place with the humerus (upper arm) bone that together form a joint. In severe cases, some people may never be able to fully open (extend) the arm, but the elbow can work very well even without the full range of motion. If bone detail is difficult to identify on an x-ray, a computed tomography (CT) scan may be done. Elbow dislocations are common and account for 10-25% of all elbow injuries in the adult population 1. [6][7][9]An open procedure, more likely when fractures are involved, can include: Once surgery is complete, the patient is typically immobilised with time frames varying based on the individual and the surgeon's protocol. Specifically, the olecranon process of the ulna (the tip of your elbow) moves into the olecranon fossa of the humerus and the trochlea of the humerus is displaced over the coronoid process of the ulna. Patient prone on gurney; Patient's arm abducted at Shoulder and flexed 90 degrees at elbow The ulnar nerve may become entrapped as it passes posteriorly around the medial epicondyle. Dr. Mark Pruzansky and Dr. Jason Pruzansky take special care to help all patients leave with adequate instructions for rehabilitation. In the most severe dislocations, the blood vessels and nerves that travel across the elbow may be injured. Other structures that can be damaged include medial and lateral collateral ligaments; medial and lateral condyles/epicondyles; transolecranon fractures; and posterior Monteggia fractures. [6][7], PED can be classified as simple or complex. Symptoms include pain, tenderness and swelling over the front of the elbow joint. If the injury has associated blood vessel or nerve injuries, patients may require additional surgery. Haan J, Schep NWL, Tuinebreijer WE, Patka P, Hartog D. O’Driscoll SW, Jupiter JB, King GJW, Hotchkiss RN, Morrey BF. A partial elbow dislocation or subluxation is difficult to identify without a professional examination. Non-displaced fractures can be treated with immobilization in a cast for 3-4 weeks. Josefsson PO, Gentz CF, Johnell O, Wendeberg B. Maripuri SN, Debnath UK, Rao P, Mohanty K.

Ligament integrity tests - varus and valgus stress test, the lateral pivot-shift test/ apprehension test (Posterolateral Rotational Instability Test). Elbow Fracture Radial Head Fracture Elbow Dislocation Posterior Olecranon Bursitis Upper Extremity Tendon Injuries Elbow Fracture Workup: XR elbow Findings: Fracture Consult: Orthopedic Surgery Patient does not currently demonstrate complications of fracture such as compartment syndrome, arterial or nerve injury. J Bone Joint Surg. A simple dislocation is classified as a dislocation without the presence of a fracture. This part is fractured through a fall onto a straightened elbow and is often associated with an elbow dislocation. Proximal portion innervates wrist flexors and FDS Hinged braces, fixators, plaster casts, and slings are utilised to keep the elbow in a position of approximately 70-80o of flexion and slight pronation. [6][7][9] Some patients may be allowed to actively move the elbow immediately post op, however this will depend on the surgeon.[15]. PARVIN, R.W. Assessment and decision making in the unstable elbow: management of simple dislocations. Dislocations occur when the radius and the ulna fall out of place with the humerus. While New York’s hospitals are bravely fighting the viral pandemic, we’re keeping our private practice office open to provide a safety-minded environment to address your urgent hand, wrist and elbow injuries. The anterior compartment of the elbow encompasses the brachial artery and ulnar and median nerves. Early mobilisation versus plaster immobilisation of simple elbow dislocations: results of the FuncSiE multicentre randomised clinical trial. Because a complex elbow dislocation is difficult to realign, the elbow must be protected with an external hinge following surgery. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. Posterior elbow dislocation (PED) occurs when the radius and ulna are forcefully driven posteriorly to the humerus.
