Clinical Orthopaedics and Related Research. This injury pattern is at highest risk for which of the following? Flouroscan of elbow with provocative lateral stress showing radial head subluxation posterior to midline of capitellum. O’Driscoll SW, Morrey BF, Korinek S, An K-N. Elbow subluxation and dislocation: a spectrum of instability. Elbow dislocations are classified according to the direction of forearm displacement relative to the distal humerus. Chronic dislocation, however, is rarely seen and may require surgical intervention. PLRI Conservative Treatment. Traumatic forearm and elbow injuries make up approximately 15% of emergency department visits for upper-extremity musculoskeletal injuries annually (1). Supination and pronation exercises are done with the elbow at 90 degrees of flexion. Phase I exercises in Safe Position; A. Pronation; B. Supination; C. Flexion; D. Extension, Medical Management (current best evidence), Physical Therapy Management (current best evidence), Example of a Conservative Treatment Guideline, Posterolateral rotatory instability (PLRI) of the elbow was first described in 1991 by. NOTE: This test is not as sensitive as the pivot shift test for diagnosing PLRI, The medial collateral ligament was still intact (incomplete dislocation), ROM and strengthening were initiated early on and progressed without difficulty, Partly due to the intact MCL which allows a more aggressive rehab, Cold whirlpool plus range of motion exercises also contributed to early motion. Figure 4. Therefore, different strategies are needed to … [9][5][12] The splint is then replaced with a hinged brace with a 30 degree extension block (Figure 9). [24] published a treatment guideline which they found to be effective for managing lateral elbow instability. Chronic dislocation, however, is rarely seen and may require surgical intervention. This type of injury can damage the bone and ligaments that surround the elbow joint and work to … Specific tests include lateral pivot shift, la… Activity is no longer limited after four to six months, but varus stresses should be avoided.[5][12]. C. Koukos 07:59. Active assisted range of motion exercises are performed for the first six weeks, and at this point, the hinged brace is unlocked. Lateral elbow instability: nonoperative, operative, and postoperative management. Table adapted from: O’Driscoll SW, Morrey BF, Korinek S, An K-N.

However, no patient outcomes are cited. 2003;85:342-346. Although this pathology is relatively common, concomitant vascular injuries are rare. Clinics in Sports Medicine. Most elbow dislocations are closed and are most frequently posterior (sometimes posterolateral or posteromedial) although anterior, medial, lateral and divergent dislocations are also infrequently encountered). Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. Acutely misdiagnosed as a simple sprain when in fact, PLRI exists. - bony displacement: - when nl elbow is extended, olecranon process & medial & lat form 3 points on straight line, & when nl elbow … [4] The brachialis, brachioradialis, biceps, and triceps all act to compress joint surfaces together. The elbow was subsequently reduced under muscular relaxation and the assistance of fluoroscopy. [3] Patients who sustain PLRI through trauma tend to have better outcomes after surgery. Orthopedics | Acute elbow dislocation in the child is readily diagnosed and treated. He only reported minimal discomfort at times. Posterolateral rotatory instability of the elbow occurs secondary to disruption of the lateral stabilizers of the elbow, including the lateral collateral ligament and extensor tendon origins. Floor Push-up Sign; C. Table-Top Relocation Test. Enroll in our online course: http://bit.ly/PTMSK Clicking, clunking, popping, locking and pain can be indicators for elbow instability. The most common patient complaints/symptoms are recurrent popping, clicking, clunking, or locking, accompanied by a sense of instability in the elbow. Elbow and shoulder resistive exercises began at just 6 days after injury. [24] These guidelines are broken up into three phases and apply to situations where the elbow was reduced operatively or non-operatively post injury. The condition is seen following an elbow dislocation , or a simple distortion, furthermore the instability was reported following surgery involving the lateral ligaments as radial head excision or lateral epicondylitis. We discuss the case of a middle-aged woman presenting with posterolateral elbow dislocation with concomitant ipsilateral closed intra-articular fracture of the distal radius. - Median nerve palsy after posterolateral elbow dislocation. Clinician applies an anterior to posterior force to the radial and ulna with the forearm in external rotation. Physiotutors. His treatment began with pain free active range of motion and cold whirpool twice a day. These symptoms occur during the act of extension and supination, especially when an axial load is applied through the upper extremity. However, he was apprehensive during a lateral pivot shift test. Clinical Orthopaedics and Related Research. The extremity was immobilized in an above-the-elbow plaster cast for three weeks. Reduction was accomplished without difficulty at the time of the injury and range of motion returned quickly. Case presentation: A 14-year-old male had a posterolateral elbow dislocation after a fall. Elbow instability. Figure 10.

O’Driscoll SW, Bell DF, Morrey BF. Rarer injuries include lateral and anterior displacements of the forearm. [24] Early on, patients can safely begin active and passive mobilization with the use of a brace and the forearm in full pronation. Evidence for non-surgical management of PLRI is scarce. Posterolateral rotatory instability of the elbow. However, closed fracture of the distal radius with ipsilateral elbow dislocation is an uncommon injury pattern. However, since the dislocation she reports intermittent popping, pain, and swelling of her elbow. [23][24] The period of immobilization depends on the level of stability and can last anywhere from three to four weeks. Spectrum of instability from subluxation to dislocation. Uhl TL, Gould M, Gieck JH. Patient is in a seated position with elbow flexed slightly and clinician gives a posterolateral drawer and supination force to the proximal forearm. Taping plus bracing increased stabilization while athlete was able to perform sports specific training. J Bone Joint Surg Am. AJR. [23] Mobilization should begin within a few days after the injury and must be protected and supervised. Fracture dislocations are common around the elbow joint. Images from: Charalambous CP, Stanley JK. Available from: Physiotutors. 2008;191:1727-1729. In 2006, Wolff et al.

Johnston J, Plancher KD, Hawkins RJ. 2000;35(1):108-110. Current Orthopaedics. [6] If the lateral ligament complex is suspected to be injured after an acute injury, stabilization of the elbow in pronation with a hinged brace should be implemented for 4-6 weeks. [2] Arthroscopy is the alternative. The condition is characterized by the presence of a prominent radial head that is caught in a buttonhole tear of the lateral collateral ligament and capsule. Using these tools, plus the available evidence, clinicians can successfully treat existing posterolateral rotary elbow instability and prevent the occurrence of it following elbow dislocation.
