Of the 28 dislocations of the shoulder and of the 20 dislocations of the elbow we have encountered at the U. S. Army Hospital, U. S. Military Academy, since June, 1954, all were reduced without anesthesia and without significant increased pain or trauma. The purpose of this paper is to emphasize the simple fact that the majority of common shoulder and elbow dislocations can be reduced without anesthesia, without increased pain or trauma to the patient. Towson, MD 21204 Although data are limited, the results have consistently shown a higher rate of success with first attempt reduction of nursemaids' elbow when the hyperpronation method was used. Hankin FM (1984) Posterior dislocation of the elbow. Suggestions on how we can improve the site? http://www.orthobullets.com/trauma/1018/elbow-dislocation, Elbow joint is very stable and requires a significant force to dislocate- most common mechanism is fall onto outstretched arm, Posterior: elbow hyperextension, arm abduction, and forearm supination together cause movement of the olecranon posteriorly (ex: falling onto an extended arm), Anterior: direct force to posterior forearm while elbow is in flexion, Most dislocations have an associated injury to capsuloligamentous stabilizers that progresses from lateral to medial, with the anterior band of medial collateral ligamental (MCL )being the last to be injured and is most often intact after injury (exceptions: trans-olecranon fracture dislocations, coronoid fractures), Second most common dislocation site in adults (shoulder is #1), Posterolateral dislocations are most common, Highest incidence in 10-20 year-old males associated with sports injuries, Varying degrees of gross swelling, deformity and instability, Perform neurovascular exam prior to manipulation and radiographs, Median and ulnar nerve are most susceptible to damage, Assess orientation of dislocation (ulna relative to humerus), Additional views: Oblique- will help assess periarticular bony involvement, Classify according to the direction of displacement of ulna relative to humerus, Posterior, posterolateral, posteromedial, lateral, medial, anterior, Emergent orthopedic consult for any patient with concern for vascular damage (loss of pulse), neurological deficits (loss of sensation, contractures) or open dislocation/fracture, Closed reduction: correction of medial or lateral displacement followed by longitudinal traction and flexion, Parvin’s method: patient lies prone with entire upper extremity hanging off the bed, downward traction is applied to the wrist for a few minutes—> olecranon slips distally, arm is then lifted gently (Method A), Meyn & Quigley method: forearm hangs off of bed, gentle downward traction is applied to wrist, olecranon is guided with opposite hand (Method B), Assess range of motion after reduction (instability can be appreciated with elbow extension), Immobilize in long arm posterior splint with elbow in 90 degrees of flexion for 1-2 week with orthopedics follow up as outpatient within 1 week for repeat radiographs, A recent multi-center study suggests that early mobilization may be superior to immobilization with better functional outcomes at 6 weeks, but comparable functional outcomes at 1 year, Prolonged immobiization (>3 weeks) is associated with poor functional outcomes, pain and contractures, If persistently unstable after reduction, splint, obtain repeat radiogrpahs to ensure elbow joint and fractures (if any) are in stable position and will need immediate orthopedics followup in the next 3-5 days for repeat radiographs and will likely need a more pronlonged immobilization course with splinting for 2-3 weeks and a hinged splint for up to 4 weeks, Most will need operative management, however, reduction and splinting may be definitive management for patients with minimally or non-displaced radial head fracture, Patients who elect for non-op management must be made aware of potential for instability of joint and future restriction of range of motion, Recurrent dislocations are uncommon (incidence is increased when terrible triad is present), Volkmann contracture (claw hand): Can develop in the pressence of massive soft tissue swelling.
