Pediatric Hand Surgery Training in Nicaragua: A Sustainable Model of Surgical Education in a Resource-Poor Environment. [PDF]

open access: yes, 2017
Recent reports have demonstrated that nearly two-thirds of the world's population do not have access to adequate surgical care, a burden that is borne disproportionately by residents of resource-poor countries.

Murine Supraspinatus Tendons Demonstrate Aging‐Related Changes in Multiscale Mechanics, Structure, and Gene Expression

open access: yesJournal of Orthopaedic Research, EarlyView.
ABSTRACT Rotator cuff disorders are common in the aging population, often leading to pain, disability, and reduced quality of life. Age‐associated changes can occur disproportionately in regions of high mechanical stress, such as the insertion site of the supraspinatus tendon, leading to increased injury rates and tendinopathies.

Glenosphere Tilt and Size Predict Shoulder Kinematics During the Hand‐to‐Back Motion After Reverse Shoulder Arthroplasty

open access: yesJournal of Orthopaedic Research, EarlyView.
ABSTRACT Internal rotation (IR) is not reliably improved after reverse shoulder arthroplasty (RSA). This study aimed to identify surgical parameters that predict kinematics of the hand‐to‐back motion (H2B) after RSA and to identify associations between kinematics and clinical outcomes after RSA.

Can Hounsfield Unit Evaluation of Preoperative CT Scans Predict Surgeon's Preference of Cementless Fixation in Total Knee Arthroplasty?

open access: yesJournal of Orthopaedic Research, EarlyView.
ABSTRACT Adequate bone quality is necessary for reliable cementless fixation during total knee arthroplasty (TKA). Hounsfield Units (HUs) can be a useful surrogate of bone density, and therefore a proxy of bone quality. We sought to determine whether HU would correlate with subjective intraoperative assessment of bone quality and hence use of ...

Exercise Initiation After Surgical Reconstruction for Rat Rotator Cuff Injury Affects Tendon Healing and Muscle Preservation

open access: yesJournal of Orthopaedic Research, EarlyView.
Wistar rats underwent supraspinatus tendon tear and reconstruction. Then, rats were divided into Cage activity, Immobilization, Immobilization + Early exercise, and Immobilization + Delayed exercise groups. After 3 and 6 weeks of surgery, histological and biomechanical analyses were performed.

A Three-dimensional Printed Low-cost Anterior Shoulder Dislocation Model for Ultrasound-guided Injection Training. [PDF]

open access: yes, 2018
Anterior shoulder dislocations are the most common, large joint dislocations that present to the emergency department (ED). Numerous studies support the use of intraarticular local anesthetic injections for the safe, effective, and time-saving reduction ...
