OBJECTIVE To determine whether a single high-velocity, low-amplitude thrust manipulation to the talocrural joint altered ankle range of motion. DESIGN A randomized, controlled and blinded study. SUBJECTS Asymptomatic male and female volunteers (N = 41). METHODS Subjects were randomly assigned into either an experimental group (n = 20) or a control group (n = 21). Both ankles of subjects i...

Objectives: To evaluate how surgical trends, costs, and outcomes for anterior cruciate ligament reconstruction (ACLR) vary with patient age. Design: Retrospective Cohort Study Setting: Outpatient Ambulatory Surgery Center Patients: 587 primary ACLR patients from 2009-2016. Inclusion criteria consisted of ACLR, complete preoperative two-year post-operative reported outcome (PRO) data. Patients w...

We describe an unusual injury to the upper cervical spine sustained during ejection from an aircraft. MRI provided an accurate and direct diagnosis of the severe ligamentous injuries.

The purpose of this study is to propose a theoretical framework based on a balanced scorecard (BSC) for performance measurement in the water desalination supply chain (WDSC). The reason for choosing this context is that the supply chain (SC) of water desalination has received a great amount of attention, due to issues related to the increased need of fresh water for agricultural, industrial and...

BACKGROUND Long-term studies of posterior cruciate ligament (PCL) reconstruction suggest that normal stability is not restored in the majority of patients. The Achilles tendon allograft is frequently utilized, although recently, the quadriceps tendon has been introduced as an alternative option due to its size and high patellar bone density. PURPOSE/HYPOTHESIS The purpose of this study was to...

STUDY DESIGN Retrospective, case-control. PURPOSE Knee morphometric risk factors for noncontact anterior cruciate ligament (ACL) injury have been a popular topic with skeletally mature patients. Little research has focused on the skeletally immature, with conflicting conclusions. This study performs a comprehensive analysis of identified parameters thought to predispose to ACL injury in a ske...

The anterior cruciate ligament (ACL) is a that mainly controls the and rotational mobility of knee joint, its surface covered by synovial membrane with large number blood vessels. In general, nutritional supply to from many capillaries in adjacent synovium. However, statistical studies distributed ACL are insufficient. this study, we examined cross-sectional histological images femoral attachme...

Introduction: The upper cervical spine includes the atlas (C1) and Axis (C2). anatomy of twovertebrae is unique from each other. Atlanto-axial articulation most unique, mobile segment spine,which largely depends on ligamentous supports based integrity odontoid for its stability. Historically,atlanto-axial subluxation was treated by reduction fusion C1-C2 joint. However, High riding vertebralart...
