Diagnosis of Elbow Fracture Patterns on Radiographs: Interobserver Reliability and Diagnostic Accuracy

Job N. Doornberg MD, PhD, Thierry G. Guitton PhD, David Ring MD, PhD

Studies of traumatic elbow instability suggest that recognition of a pattern in the combination and character of the fractures and joint displacements helps predict soft tissue injury and guide the treatment of traumatic elbow instability, but there is no evidence that patterns can be identified reliably.

Is Posterior Synovial Plica Excision Necessary for Refractory Lateral Epicondylitis of the Elbow?

In Hyeok Rhyou MD, Kang Wook Kim MD

Arthroscopic treatments for lateral epicondylitis including débridement of the extensor carpi radialis brevis (ECRB) origin (Baker technique) or resection of the radiocapitellar synovial plica reportedly improve symptoms. However the etiology of the disease and the role of the plica remain unclear.

The Natural Progression of Adult Elbow Osteonecrosis Related To Corticosteroid Treatment

Charles-Henri Flouzat-Lachaniette MD, Chaib Younes MD, William Delblond MD, Nicolas Dupuy MD, Philippe Hernigou MD

In patients with corticosteroid treatment, the elbow is a rare site of osteonecrosis; there is little information about the rate and risk factors of disease progression in symptomatic and asymptomatic elbows.

Preoperative Imaging Criteria for Unstable Osteochondritis Dissecans of the Capitellum

Hiroshi Satake MD, PhD, Masatoshi Takahara MD, PhD, Mikio Harada MD, PhD, Masahiro Maruyama MD

The stability of an osteochondritis dissecans (OCD) lesion of the humeral capitellum may be determined by intraoperative probing with unstable lesions being displaceable. Although preoperative imaging is used to diagnose and determine treatment of these lesions, it is unclear whether unstable lesions on imaging correspond to those found intraoperatively.

Minimal Epicondylectomy Improves Neurologic Deficits in Moderate to Severe Cubital Tunnel Syndrome

Kang Wook Kim MD, Hyuk Jin Lee MD, Seung Hwan Rhee MD, Goo Hyun Baek MD, PhD

Previous studies of minimal medial epicondylectomy for cubital tunnel syndrome included patients with mild disease, making it difficult to determine how much this procedure improved sensory and motor impairments in patients with moderate to severe disease.

Does Posteromedial Chondromalacia Reduce Rate of Return to Play After Ulnar Collateral Ligament Reconstruction?

Daryl C. Osbahr MD, Joshua S. Dines MD, Andrew J. Rosenbaum MD, Joseph T. Nguyen MPH, David W. Altchek MD

Biomechanical studies suggest ulnohumeral chondral and ligamentous overload (UCLO) explains the development of posteromedial chondromalacia (PMC) in throwing athletes with ulnar collateral ligament (UCL) insufficiency. UCL reconstruction reportedly allows 90% of baseball players to return to prior or a higher level of play; however, players with concomitant posteromedial chondromalacia may experience lower rates of return to play.

Validity of Goniometric Elbow Measurements: Comparative Study with a Radiographic Method

Julien Chapleau MD, Fanny Canet MScA, Yvan Petit PhD, G-Yves Laflamme MD, FRCSC, Dominique M. Rouleau MD, MSc, FRCSC

A universal goniometer is commonly used to measure the elbow’s ROM and carrying angle; however, some authors question its poor intertester reliability.
