Introduction: The objective of this paper is to evaluate the results of a series of patients with posterolateral elbow instability treated with reconstruction of the ulnar collateral ligament using tendon graft.Methods: We reported 10 patients with a mean age of 47 years. Tested Concept, Closed reduction, hinged external fixator, Closed reduction, acute surgical repair of the lateral collateral ligament complex, Open reduction and surgical repair of the lateral collateral ligament complex, Closed reduction, splinting & early passive ROM, Closed reduction, splinting & early active ROM, (OBQ10.252) It is proposed that the following factors contributed to the athlete's early return: Low-level evidence exists regarding the physical therapy treatment of PLRI. 2006;64(3,4):166-171. Available from: Jeon I-H, Micic ID, Yamamoto N, Morrey BF. Wolff AL, Hotchkiss RN. Table 1. Elbow instability is a looseness in the elbow joint that may cause the joint to catch, pop, or slide out of place during certain arm movements. Assess radiographs for associated fractures, such as supracondylar fracture of the distal humerus, radial head fracture, and coronoid process fracture. Therefore, different strategies are needed to … The elbow is the second most commonly dislocated large joint in the body, with posterolateral rotatory instability (PLRI) being the most frequently observed pattern of instability.1, 2 Since its initial description in 1991, the mechanism, evaluation, and treatment of PLRI of the elbow has been studied in detail. 1996;15(2):307-329. 2010;6:12-25. On physical exam he is neurologically intact and has a palpable radial pulse. Posterior or posterolateral displacement of the ulna relative to the distal humerus is the most common simple dislocation with approximately 90% occurring this way (see image). Proficient communication with referring health care providers is essential, and a thorough understanding of the anatomy and biomechanics surrounding the condition is required. These symptoms may, in particular, brought up by activities which place the elbow in its unstable position of external rotation of the forearm with valgus and axial loading, such as pushing up from a chair or doing push-ups. 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. Posterolateral rotatory instability (PLRI) is the most common cause of residual instability following a simple elbow dislocation. Chronic dislocation, however, is rarely seen and may require surgical intervention. In order to optimize his clinical outcomes, which of the following treatment and rehabilitation protocols should be avoided? What percent of the proximal radial head articulates with the proximal ulna? Posterolateral rotatory instability should be considered in a patient who complains of vague elbow pain and giving way with a history of an elbow dislocation or previous lateral elbow surgery. They are summarized in Table 3: Figure 10 depicts the correct position to perform the exercises in Phase 1[24]. [24] published a treatment guideline which they found to be effective for managing lateral elbow instability. However, if there is an associated fracture, the treatment is determined depending on the position and displace- By the 9th day, the athlete began bouncing a basketball against a wall with both hands for proprioception and endurance training. Elbow dislocation is the second most common adult joint dislocation; most are posterior or posterolateral dislocations.1. posterolateral elbow dislocation with ipsilateral radial and ulnar shaft fractures and underwent closed reduction and plate fixation. [3], Patients with PLRI may present with a spectrum of different symptoms ranging from vague pain in the elbow to recurrent posterolateral dislocations. The elbow was subsequently reduced under muscular relaxation and the assistance of fluoroscopy. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). Assess radiographs for associated fractures, such as supracondylar fracture of the distal humerus, radial head fracture, and coronoid process fracture. Simple posterolateral elbow dislocations (SPLED) may be treated nonoperatively using closed reduction, followed by controlled mobilization. Supine with arm overhead. [9] The aim of bracing is to limit valgus loading and supination. Although the topic is currently debated, the radial ulnohumeral ligament does play an important role in this instability. A 34-year-old male falls from a roof and sustains a right elbow dislocation that is closed reduced in the emergency room. We report our experience with this case, which was not diagnosed correctly by plain radiographs. Valgus force may induce the commonly seen posterolateral elbow dislocation. He had full elbow range of motion, strength, and function. Acta Orthop Scand. Acute posterolateral rotator elbow dislocation in a child is rare and can be easily misdiagnosed due to immaturity of the epiphysis. J Bone Joint Surg Am. A. Radiographs after initial reduction showed a fragment entrapped into the humero-cubital joint. Journal of Orthopaedic Surgery and Research. (OBQ12.183) Treatment of posteromedial and posterolateral dislocation of the acute unstable elbow joint: a strategic approach In unstable elbow dislocation, PLDL and PMDL are caused by different mechanisms following damage to different structures. Most consist of posterior or posterolateral displacement although less commonly lateral and anterior displacement of the forearm can also occur. [23] Mobilization should begin within a few days after the injury and must be protected and supervised. Very rarely it can be irreducible and requires open reduction. Elbow Dislocation • Usually posterolateral • Can dislocate with anterior band of MCL intact • Posteromedial pattern • Less common • Possibly more unstable . Elbow Dislocation, LCL/ MCL Repair and internal bracing Feat. [4] Patients with PLRI should avoid placing the arm in abduction or internal rotation while performing elbow flexion and extension range of motion exercises. Figure 24.2 AP (A) and lateral (B) radiographs of a simple posterolateral elbow dislocation. Only four cases of irreducible posterolateral elbow dislocation have been described in the literature over the past 50 years. This posterolateral dimple is typical of posterolateral elbow dislocation. Supination and pronation exercises are done with the elbow at 90 degrees of flexion. However, closed fracture of the distal radius with ipsilateral elbow dislocation is an uncommon injury pattern. Figure 10. Posterolateral elbow joint instability, prior described by more authors, was experimentally shown to be caused by insufficiency of the Lateral Collateral Ligament Complex. It has been reported that uncomplicated dislocation of the elbow joint may be associated with a decreased range of motion, degenerative changes in the elbow joint, ectopic calcification, or neurological deficits. A 26-year-old male wrestler suffers the elbow injury shown in Figure A. The author contends that further evidence is needed to study the outcome of certain rehabilitation techniques. Active and passive provocative tests can be helpful to make a diagnosis. 2006;19(2):238-245. Tabletop Relocation Test | Posterolateral Rotatory Instability of the Elbow. Rehab must be guided by each patient's unique case of PLRI, taking into consideration their goals and previous level of activity. Charalambous CP, Stanley JK. Current Orthopaedics. A 14-year-old male had a posterolateral elbow dislocation after a fall. 2008;90:272-279. What is the most common mode of failure of the lateral ulnar collateral ligament associated with an elbow dislocation? Activity is no longer limited after four to six months, but varus stresses should be avoided.[5][12]. Therapists must utilize clinical judgment and treat each case individually. Elbow instability is a looseness in the elbow joint that may cause the joint to catch, pop, or slide out of place during certain arm movements. International SportMed Journal. It is important to nota that, A) with the exception of the coronoid fracture, the elbow was otherwise intact and, B) the elbows were tested for degree of posterior translation. Most patients can recall a traumatic event, frank elbow dislocationor fall in outstretched hands. 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. In most cases Physiopedia articles are a secondary source and so should not be used as references. Laxity was not found, but the apprehension suggested that the LUCL may still have residual deficiency. Closed reduction with traction was performed. Bulletin of the NYU Hospital for Joint Diseases. C. Koukos 08:13. [9] Pushing down with the upper extremity to rise from a seated position, performing press-up/push-up exercises, and pushing heavy objects with an extended arm are common activities that patients with PLRI report that reproduce their symptoms. I I I It most often occurs as a result of an injury — typically, an elbow dislocation. - indications for this approach include frxs of distal humerus, old posterior elbow dislocations, radial head frx, radial head excisions, arthroplasties, fixation of distal biceps tendon rupture, and resection of proximal radial-ulnar synostosis; - it is also indicated for elbow flexion contractures If a patient is deficient in one or more of these key supporting structures, they may be predisposed to PLRI. 2005;87(1):54-61. Journal of Athletic Training. [5][23] Much like treatment post surgery, immobilization after reduction in full pronation and 90-120 degrees of elbow flexion is encouraged to promote stability and restrict destabilizing forces on the elbow. Hickey DG, Loebenberg MI. 1999;65(4):404-415. However, closed fracture of the distal radius with ipsilateral elbow dislocation is an uncommon injury pattern.

Acute posterolateral rotator elbow dislocation in a child is rare and can be easily misdiagnosed due to immaturity of the epiphysis. Sanchez-Sotelo J, Morrey BF, O’Driscoll SW. Ligamentous repair and reconstruction for posterolateral rotatory instability of the elbow. She is distally neurovascularly intact. Evidence for non-surgical management of PLRI is scarce. However, evidence is lacking regarding how the strengthening of these muscles directly reduces instability. Orthopedics | Acute elbow dislocation in the child is readily diagnosed and treated. She had an excellent outcome after 22 months of follow-up. Clinician applies an anterior to posterior force to the radial and ulna with the forearm in external rotation. Dislocation of the elbow joint is the second most common dislocation after the shoulder joint. Dislocations with associated fractures or so-called complex dislocations of the elbow can be challenging to diagnose and treat. The treatment and outcomes remains controversial. The most common patient complaints/symptoms are recurrent popping, clicking, clunking, or locking, accompanied by a sense of instability in the elbow. Her radiograph is shown in Figure B. [12] Clinicians must consider each patient’s presentation and fine-tune their treatment in order to achieve the ideal balance of elbow stability and mobility. After an aggressive rehabilitation program, the athlete was able to return to full sports activities in only three weeks. 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. This injury pattern is at highest risk for which of the following? Elbow dislocations in children are less frequent than in adults, and majority of the dislocations are toward the posterolateral. If you believe that this Physiopedia article is the primary source for the information you are refering to, you can use the button below to access a related citation statement. [25], found that strengthening the elbow flexors throughout full range of motion significantly increased elbow stiffness compared to strengthening in a limited range. Whereas the importance of early recognition of neurovascular compromise is well described and nearly universally recognized, the importance of timely and correct treatment in preventing delayed complications and potential instability is often less emphasized in the radiology literature. Elbow dislocation can lead to instability and stiffness of the elbow. Uhl TL, Gould M, Gieck JH. elbow dislocations are the most common major joint dislocation second to the shoulder most common dislocated joint in children account for 10-25% of injuries to the elbow posterolateral is the most common type of dislocation (80%) Abstract Background: Dislocation of the elbow joint is the second most common dislocation in the upper extremity, dislocation of the shoulder being the most common. Lastly, extreme posterolateral displacement may disrupt the MCL complex. Read more, © Physiopedia 2020 | Physiopedia is a registered charity in the UK, no. Time from posterolateral dislocation to surgery was 16 months. Tested Concept, (OBQ08.149) O’Driscoll SW, Bell DF, Morrey BF. A positive lateral pivot-shift test suggests posterolateral rotatory instability. Elbow is flexed to 40. Elbow dislocation is the second most common adult joint dislocation; most are posterior or posterolateral dislocations.1. 2008;191:1727-1729. Lateral elbow instability: nonoperative, operative, and postoperative management. However, since the dislocation she reports intermittent popping, pain, and swelling of her elbow. Clinicians can use this information as a guideline when treating patients with PLRI. Methods: We reported 10 patients with a mean age of 47 years. Tested Concept, Valgus posterolateral rotatory instability, Elbow instability when pushing oneself up from a seated position in a chair, (OBQ10.69) Flouroscan of elbow with provocative lateral stress showing radial head subluxation posterior to midline of capitellum. 2001;83:1823-1828. Clinical presentation of posterolateral rotatory instability of the elbow in children Lisa L. Lattanza Washington University School of Medicine ... Six patients had prior elbow dislocation, and three had an isolatedelbow fracture. Video 2 (Valgus Instability) is a preoperative demonstration of a valgus stress test under general anesthesia. Bredella MA, Tirman PFJ, Fritz RC, Feller JF, Wischer TK, Genant HK. Tested Concept, Immediate active and active-assist range of motion through a stable arc, Initial splinting and immobilization for 4 weeks followed by physical therapy, Initial splinting in 90 degrees of flexion with neutral forearm rotation, A range of motion protocol that limits full extension in the early phases of rehab, Light duty use of the affected arm immediately following immobilization, (OBQ08.192) The forearm remains in pronation for flexion and extension exercises. [6][12][9][11] This is especially true when conservative treatment has failed to address pain and functional limitations. After 8 weeks, strengthening can begin, but may begin in as little as one week, depending on the surgeon and technique used. [12], Surgery aims to reconstruct the LUCL, thereby restoring rotational stability to the humeroulnar joint. Journal of Hand Therapy. Very rarely it can be irreducible and require open reduction. Taping plus bracing increased stabilization while athlete was able to perform sports specific training. - Median nerve palsy after posterolateral elbow dislocation. A 30-year-old woman falls onto an outstretched arm while rollerblading. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. [5] Muscle activity is a significant contributer to poterolateral stability of the elbow. Radiographs of the elbow were repeated, which showed a posterolateral dislocation of the elbow (figs 3 and 4). 2000;35(1):108-110. These symptoms occur during the act of extension and supination, especially when an axial load is applied through the upper extremity. elbow dislocations are the most common major joint dislocation second to the shoulder, account for 10-25% of injuries to the elbow, predominantly affects patients between age 10-20 years old, supination/external rotation of the forearm, a varus posteromedial mechanism (combined with axial load and forearm external rotation) has also been reported, posterior dislocations may involve more than one injury mechanism, associated with complete or near complete circular disruption of capsuloligamentous stabilizers, progression of injury is from lateral to medial, by avulsion of the lateral epicondylar origin, midsubstance LCL tears are less common but do occur, Static and dynamic stabilizers confer stability to the elbow, origins of the common flexor and extensor tendons, muscles that cross the elbow joint, which apply compressive (stabilizing) force, See complete Anatomy and Biomechanics of Elbow, based on anatomic location of olecranon relative to humerus, elbow dislocation with no associated fracture, accounts for 50-60% of elbow dislocations, elbow dislocation with associated fracture, elbow dislocation associated with a LUCL tear, radial head fracture, and coronoid tip fracture, radial head fractures occur in up to 10% of elbow dislocations, elbow injury associated with an LCL tear and a coronoid fracture, the status of the skin - evaluate for open injuries, concomitant injuries occur in 10-15% of elbow dislocations, assess joint congruency, especially after attempted reduction, assess for associated periarticular fractures, useful to identify associated periarticular fractures, recurrent instability after simple dislocations is rare (<1-2% of dislocations), hinged external fixator indicated in chronic dislocation to protect the reconstruction and allow early range of motion, ensure patient has sufficient analgesia to allow for adequate muscle relaxation. Murthi AM, Keener JD, Armstrong AD, Getz CL. Figure 7. 14 A: PLRI. Reduction was accomplished without difficulty at the time of the injury and range of motion returned quickly. Orthopedics | Acute elbow dislocation in the child is readily diagnosed and treated. Table 3. Fracture dislocations are common around the elbow joint. Specifically, the olecranon process of the ulna moves into the olecranon fossa of the humerus and the trochlea of the humerus is displaced over the coronoid process of the ulna. 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).
