Traumatic atlanto-occipital dislocation with survival is possible and , in fact may be relatively more common than once thought. The spectrum of neurologic manifestations is broader than previously described and does not necessarily end in death or tragic neurologic deficit. Radiographic diagnosis of this injury may be d ifficult , particularly in the longitudinal distraction-dislocation type. ...

In this case report clinical and technical lessons including seven years follow up learned from a flexion-distraction, highly unstable cervical spine injury causing a complete separation of C6-7 cervical segment with tetraparesis in a 23-month-old boy, are presented. To our knowledge this is the only documented case in medical literature where adult size implants (cage, plate and lateral mass s...

To reach the level of elite, most baseball pitchers need to consistently produce high ball velocity but avoid high joint loads at the shoulder and elbow that may lead to injury. This study examined the relationship between fastball velocity and variations in throwing mechanics within 19 baseball pitchers who were analyzed via 3-D high-speed motion analysis. Inclusion in the study required each ...

INTRODUCTION Various treatment options are in use to address severe knee flexion contractures in children. Their success depends on an adequate selection of the proper one applying to each individual anatomical situation. HYPOTHESIS Applied to limb deformity, the Ilizarov technique combines progressive correction, to joint structures flexibility restitution in case of severe knee flexion cont...

BACKGROUND Internal tibial rotation is a risk factor for anterior cruciate ligament (ACL) injury. The effect of restraining tibial rotation (RTR) to prevent ACL injury during single-leg landing is not well understood. We aimed to investigate the effect of impact load and RTR on ACL injury with respect to flexion angle. We hypothesized that RTR could protect the knee from ACL injury compared to ...

This preliminary study aimed to quantify the magnitude of the peak shoulder distraction force during the bowling action of female cricket fast bowlers. An eight camera Vicon motion analysis system operating at 120 Hz recorded the fast bowling actions of 18 Australian female fast bowlers. A three segment inverse solution model of the bowling arm was used to calculate the shoulder distraction for...

BACKGROUND After complete five-level root brachial plexus injury, free functional muscle transfer and intercostal nerve transfer to the musculocutaneous nerve are two potential reconstructive options for elbow flexion. The aim of this study was to determine the outcomes of free functional muscle transfer versus intercostal nerve-to-musculocutaneous nerve transfers with respect to strength. ME...

ABSTRACT The primary aim of the study is to determine rate traction-related complications in hip arthroscopy (HA) including perineal compression and distraction injuries, secondary objective report incidence HA found on studies selected by a systematic review. Preferred Reporting Items for Systematic Reviews Meta-Analyses guidelines were used data extraction from PubMed Cochrane databases obtai...
