OBJECTIVE To carry out an anatomical study of the medial collateral ligament, an important elbow stabilizer in different degrees of elbow flexion-extension. METHODS Forty elbows were dissected in order to analyze the functional behavior of the anterior, posterior and transverse ligament bands during valgus stress maneuvers of the elbow in different degrees of flexion and extension. Two groups...

INTRODUCTION Posterior dislocation of the elbow is usually associated with trauma to the joint with a reported incidence of 3%to 6%. Chronic instability is usually symptomatic following the initial injury. CASE PRESENTATION We report a case of posterior dislocation of the elbow occurring in a patient while using her arm to lift herself using a monkey pole on the second day following a total h...

ateral stability of the elbow depends on the integrity of the lateral collateral ligament and secondary softtissue restraints. Posterolateral rotatory subluxation of the elbow has been recognized in association with elbow trauma, surgery for epicondylitis, and congenital cubitus varus deformity. While abnormal signal changes on magnetic resonance imaging have been shown to include the lateral c...

Posterolateral rotatory instability (PLRI) is caused by injury to the lateral collateral ligament complex, usually from elbow dislocation; fracture dislocation, iatrogenic injury, or varus malalignment of the elbow. This is characterized by the external rotation of the radius and ulna in reference to the distal humerus. Further, it is manifested as posterior subluxation of the radial head in re...

Elbow arthroscopy is a tool useful for the treatment of a variety of pathologies about the elbow. The major indications for elbow arthroscopy include débridement for septic elbow arthritis, synovectomy for inflammatory arthritis, débridement for osteoarthritis, loose body extraction, contracture release, treatment of osteochondral defects and selected fractures or instability, and tennis elbow ...

BACKGROUND Nonsurgical and surgical treatments such as immobilization, transarticular pinning, and hinged or nonhinged external fixation have been used to treat unstable elbows. These methods all have drawbacks. We thought that a bent Steinmann pin introduced through the axis of ulnohumeral rotation and attached to the ulna could provide an improved method of treatment and that this could resul...
