Recovery of Motor Nerve Injuries Associated With Displaced, Extension-type Pediatric Supracondylar Humerus Fractures.

Background: Nerve injuries occur in approximately 11% of pediatric extension supracondylar humerus fractures (SCHF), yet there is scarce literature to guide clinicians on management. The primary goal of this study was to report the presentation, treatment, and outcome of motor nerve injuries associated with extension SCHF. Our secondary goal was to determine which injury and treatment factors were associated with prolonged motor nerve recovery.

Ray Resection for Progressive Macrodactyly of the Hand: Surgical Technique and Illustrative Cases.

Macrodactyly of the hand is a rare condition. Although the underlying mechanism is being more fully elucidated, surgical intervention is typically required to improve the size and function of the affected digits. However, when an involved digit(s) is rapidly progressive in size, ray resection amputation may be the most appropriate treatment.

Using resident input to identify and integrate essential components of a foot and ankle rotation.

Background: Foot and ankle surgery is one of the orthopaedic subspecialties to which residents not uncommonly receive limited exposure. Therefore, it is important to identify what both faculty and residents regard as fundamental to a foot and ankle rotation. The purposes of this study were to identify the essential components of a foot and ankle rotation and to correlate these with the American Orthopaedic Foot and Society (AOFAS) core curriculum, and to discuss how to integrate resident input and AOFAS guidelines into a valued foot and ankle rotation.

Simulator assessment of innate endovascular aptitude versus empirically correct performance.

Objective: Prior work has established that performance on an endovascular simulator incorporating tactile feedback (haptics) correlates with previous endovascular experience and can be improved by training. This study was designed to test the ability to define and measure innate endovascular aptitude and empirically correct performance and to determine whether these are two different things.

Methods: Subjects ranging in endovascular skill level from novice to expert were surveyed to determine video game experience and skill, endovascular level of training, and endovascular experience.

Use of computer simulation for determining endovascular skill levels in a carotid stenting model.

Objectives: The purpose of this study was to determine whether performance on a simulator model of carotid artery stenting correlates with previous endovascular experience and to assess the effects of repetition and training.

Methods: Participants were stratified to untrained and advanced skill groups on the basis of number of endovascular procedures previously performed. Baseline performance was assessed by means of a pretest, and participants were randomized to practice and no-practice groups.
