BACKGROUND AND PURPOSE Radial head fractures are common, and may be associated with other injuries of clinical importance. We present the results of a standard additional MRI scan for patients with a radial head fracture. PATIENTS AND METHODS 44 patients (mean age 47 years) with 46 radial head fractures underwent MRI. 17 elbows had a Mason type-I fracture, 23 a Mason type-II fracture, and 6 e...

conclusions the clinical examination is an important and accurate diagnostic modality for evaluation of traumatic derangement of the knee joint. it is noninvasive, easy, available, and valuable diagnostic modality. the mri is an accurate diagnostic modality. it can be used whenever there is an uncertain indication for arthroscopy. however, costs have to be kept in mind, especially in patients w...

Medial collateral ligament (MCL) injuries are a common knee injury, especially in competitive athletes. Identifying genetic loci associated with MCL injury could shed light on its etiology. A genome-wide association screen was performed using data from the Research Program in Genes, Environment and Health (RPGEH) including 1 572 cases of MCL injury and 100 931 controls. 2 SNPs (rs80351309 and r...

Ligament function in restraining axial rotation of the tibia relative to the femur cannot be revealed by analysis of ligament forces alone. The action of the articular surfaces should be taken into account as well. In this study, three-dimensional mathematical models of four human knee joints were used to determine the limits of axial rotation between 0 and 90 degrees of flexion, whereby the fo...

Background: Anatomic single bundle is a widely accepted technique for anterior cruciate ligament (ACL) reconstruction. The research question: are transverse pins safe to fix the ACL graft on the femoral side in anatomic single bundle ACL reconstruction? Material and Methods: Ten cadaveric femoral dry bones were tested in this study. Thirty mm long sockets were prepared in the center of the anat...

Denervation degrades normal ligament properties and impairs ligament healing. This suggests that secreted neuromediators, such as neuropeptides, could be modulating cell metabolism in ligament and scar tissue. To test this hypothesis we investigated the effect of exogenous substance P (SP), neuropeptide Y (NPY) or calcitonin gene-related peptide (CGRP) on the mRNA levels for proteins associated...

What are the most common causes of anterior cruciate ligament (ACL) injury in athletes? The most common causes for ACL injury in athletes are noncontact, twisting injuries that involved a pivoting motion. For example, in sports such as soccer, athletes frequently perform motions that plant and twist the lower extremities, putting those who play soccer at one of the highest likelihoods of ACL in...

Introduction: Irreducible posterolateral dislocation of the knee is a rare condition. Due to limited reports available, it common dilemma whether closed reduction should be attempted at all or an open surgery only method. “Dimple Sign'' can found in presence injured medial structure, including collateral ligament rupture (MCL), failure recognize this sign may lead repeated attempts close manual...

Injury to the structures of the medial elbow is common among baseball players. The injury can result from repeated valgus stress of the elbow. Several types of injury to the structures of the medial elbow have been reported.1 These injuries cause valgus instability and pain of medial aspect of the elbow during pitch.2e4 Avulsion fractures of the sublime tubercle of the ulna are rare and general...
