Pure varus posteromedial rotatory instability of the elbow: Radiographic findings, treatment, and outcomes.

Introduction: Although varus posteromedial rotatory instability (VPMRI) is a subtle elbow injury that involves anteromedial coronoid facet (AMCF) fracture and ligamentous injuries, treatment options and outcomes of VPMRI remains controversial. The aim of this study was to investigate radiographic findings, treatments, and outcomes of a large series of VPMRI.

Methods: We retrospectively reviewed 91 pure VPMRI cases with AMCF fracture (O'Driscoll classification anteromedial type) which were treated at 6 hospitals.

High reliability and accuracy of dynamic magnetic resonance imaging in the diagnosis of cervical Spondylotic myelopathy: a multicenter study.

Background: Cervical spondylotic myelopathy (CSM) is a critical condition that results in significant neurologic deterioration. An accurate diagnosis is essential for determining its outcome and prognosis. The pathology is strongly associated with dynamic factors; therefore, dynamic magnetic resonance (MR) image could be crucial to accurately detect CSM.

Secondary signs on preoperative CT as predictive factors for febrile urinary tract infection after ureteroscopic lithotripsy.

Background: Febrile urinary tract infection (UTI) is one of the most common complications after ureteroscopic lithotripsy (URS). We evaluated the effect of secondary signs on preoperative computed tomography (CT) for febrile UTI after URS.

Methods: In total, 182 patients who underwent URS for ureteral stones from January 2013 to December 2015 were retrospectively included in this study.

Efficacy of a Decision Aid Consisting of a Video and Booklet on Advance Care Planning for Advanced Cancer Patients: Randomized Controlled Trial.

Context: Few randomized controlled trials of advance care planning (ACP) with a decision aid (DA) show an effect on patient preferences for end-of-life (EOL) care over time, especially in racial/ethnic settings outside the U.S.

Objectives: The objective of this study was to examine the effect of a decision aid consisting of a video and an ACP booklet for EOL care preferences among patients with advanced cancer.

Impact of wedge-shaped resection of the posterior bony arch on postoperative outcomes after open door laminoplasty in the cervical spine: a 2-year follow-up study.

Background Context: Open door laminoplasty (ODLP) can also lead to significant postoperative motion restriction that further increases over time, for which one of the possible factors is the bony impingement between neighboring posterior bony arches. Previously, we reported this phenomenon and modified technique of ODLP, wedge-shaped resection of the posterior bony arch that produced greater range of motion (ROM) of the cervical spine and less posterior neck pain compared with conventional ODLP (cODLP) in 1-year follow-up time, but no longer follow-up outcomes of the surgical technique has been reported.

Purpose: The study aimed to thoroughly evaluate the impact of posterior bony impingement following ODLP on postoperative cervical motion and related outcomes, and to compare postoperative outcomes of conventional ODLP (cODLP with those of modified ODLP (mODLP) in 2-year follow-up times.

The Interrater and Intrarater Agreement of a Modified Neer Classification System and Associated Treatment Choice for Lateral Clavicle Fractures.

Background: As there is substantial variation in the classification and diagnosis of lateral clavicle fractures, proper management can be challenging. Although the Neer classification system modified by Craig has been widely used, no study has assessed its validity through inter- and intrarater agreement.

Purpose: To determine the inter- and intrarater agreement of the modified Neer classification system and associated treatment choice for lateral clavicle fractures and to assess whether 3-dimensional computed tomography (3D CT) improves the level of agreement.

Strategic approach to O'Driscoll type 2 anteromedial coronoid facet fracture.

Background: The purpose of this study was to suggest a strategic approach to the management of anteromedial coronoid facet (AMCF) fracture that is related to posteromedial rotational instability of the elbow through investigation of the surgical outcome of diverse combinations, including internal fixation of AMCF fractures and repair of collateral ligament injury.

Methods: The study enrolled 18 patients. On the basis of the size of the coronoid fracture and the degree of the soft tissue injuries that were evaluated with computed tomography, magnetic resonance imaging, and varus stress test under anesthesia, these fractures were managed differently.

Collateral ligament injury in the displaced radial head and neck fracture: correlation with fracture morphology and management strategy to the torn ulnar collateral ligament.

Background: The purpose of our study was to correlate the morphology of displaced radial head and neck (DRHN) fractures with associated ligament injuries and evaluate the outcomes of management of the torn ulnar collateral ligament (UCL).

Methods: Twenty-nine surgically treated patients presenting with a DRHN fracture were classified using the Charalambous classification by 3-dimensional computed tomography. Accordingly, the collateral ligament and overlying muscle injuries and bony contusions were investigated with magnetic resonance imaging.

New mechanism of the posterior elbow dislocation.

Purpose: To suggest a new model on the most common kind of posterior elbow dislocation using MRI findings on acute elbow injuries.

Methods: Fifteen patients with simple elbow dislocation (Group A) and 19 patients sustaining pure ligament injuries (Group B) were enrolled in this study. Using MRI scans, bony contusion at radial head and posterior capitellum (lateral bone contusion) and medial aspect of the ulnohumeral joint (medial bone contusion) were investigated with the injury patterns of the collateral ligament and overlying muscles.
