Rarer injuries include lateral and anterior displacements of the forearm. [4] Patients with PLRI should avoid placing the arm in abduction or internal rotation while performing elbow flexion and extension range of motion exercises. A 14-year-old male had a posterolateral elbow dislocation after a fall. This is the first case of occult posterolateral rotator elbow dislocation in combination with an olecranon fracture. - additional deficiency of radial collateral ligament=Dislocation - references: - The effect of arthroscopic sectioning of the lateral ligament complex of the elbow on posterolateral rotatory stability. - Ligamentous stabilizers against posterolateral rotatory instability of the elbow. 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. Tested Concept, (OBQ08.149) 2008;22:90-103. He is treated with closed reduction in the emergency room. However, evidence is lacking regarding how the strengthening of these muscles directly reduces instability. Hickey DG, Loebenberg MI. [23] Mobilization should begin within a few days after the injury and must be protected and supervised. Elbow instability. 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. Supination and pronation exercises are done with the elbow at 90 degrees of flexion. Dislocations with associated fractures or so-called complex dislocations of the elbow can be challenging to diagnose and treat. Elbow dislocations in children are uncommon injuries. We report what is, to the best of our knowledge, the first case of occult posterolateral rotator elbow dislocation in combination with an olecranon fracture, which occurred in a child who was not diagnosed correctly by plain radiographs. Specific tests include lateral pivot shift, la… In order to optimize his clinical outcomes, which of the following treatment and rehabilitation protocols should be avoided? He had full elbow range of motion, strength, and function. Introduction: Elbow dislocations in children are uncommon injuries. Therefore, treatment should be aimed at ensuring that the stabilizers of the humeroulnar joint are efficient. A randomized controlled trial by Ocarino et al. What is the most common mode of failure of the lateral ulnar collateral ligament associated with an elbow dislocation? Rehab must be guided by each patient's unique case of PLRI, taking into consideration their goals and previous level of activity. A posterior elbow dislocation often occurs when a person falls on an outstretched hand, posteriorly directed force at the elbow joint causes dislocation at the ulnohumeral and radiocapitellar articulations. Valgus force may induce the commonly seen posterolateral elbow dislocation. 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) Tested Concept, Type in at least one full word to see suggestions list, 2018 Orthopaedic Summit Evolving Techniques, The Unstable Elbow - Jorge L.

Dr. Mark S. Cohen), Chronic terrible triad of the elbow in a 63M. A form of elbow instability characterized by posterolateral subluxation or dislocation of the radiocapitellar and ulnohumeral joints usually associated with a traumatic elbow dislocation caused by insufficiency of the lateral elbow collateral ligament complex caused primarily by insufficiency of the LUCL 1992;280:186-197. In 2006, Wolff et al. Methods: We reported 10 patients with a mean age of 47 years. [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. [3], The immobilization period after surgery varies depending on the technique. Goals of treatment include patient education to avoid unstable positions of the arm, as well as motion restoration without compromising the stability of the elbow. 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.
