CONTEXT Researchers have suggested that large landing forces, excessive quadriceps activity, and an erect posture during landing are risk factors for anterior cruciate ligament (ACL) injury. The influence of knee kinematics on these risk factors has been investigated extensively, but trunk positioning has received little attention. OBJECTIVE To determine the effect of trunk flexion on landing...

There is a lack of studies investigating gender differences in whole-body kinematics during single-leg landings from increasing vertical heights and horizontal distances. This study determined the main effects and interactions of gender, vertical height, and horizontal distance on whole-body joint kinematics during single-leg landings, and established whether these findings could explain the ge...

Women are more prone to anterior cruciate ligament (ACL) injury during cutting sports than men. The purpose of this study was to examine knee kinematic and ground reaction forces (GRF) differences between genders during cutting. Male and female athletes performed cutting trials while force platform and video data were recorded (180 Hz). Differences (p < . 05) were observed between groups for kn...

INTRODUCTION Upper brachial plexus injury in adults causes loss of elbow fl exion; when the primary nerve surgery has failed or the patient seeks treatment after 12 months of injury and pedicled muscle transfers are required. Most commonly, the latissimus dorsi or the Steindler flexorplasty is used. MATERIAL AND METHODS We have transferred one of the heads of triceps muscle to restore the elb...

CONTEXT Injuries to the anterior cruciate ligament (ACL) occur because of excessive loading on the knee. ACL injury prevention programs can influence sagittal plane ACL loading factors and vertical ground reaction force (VGRF). OBJECTIVE To determine the influence of ACL injury prevention programs on sagittal plane knee biomechanics (anterior tibial shear force, knee flexion angle/moments) an...

STUDY DESIGN This is a retrospective study. PURPOSE We wanted to evaluate the clinical results of surgical and conservative treatment for cervical tear drop fracture. OVERVIEW OF LITERATURE The tear drop fracture of the lower cervical spine is generally associated with a high incidence of neurological deficits and surgery is needed to treat this injury. Tear drop fracture of C2 is usually a...

Introduction: Clinical evidence suggests that hamstring tightness influences lumbar pelvic rhythm and shortened increase the risk of injury to spine. Objectives: To determine association with tilt in standing position, trunk, range motion during forward bending among sewing machine operators Methods: A descriptive cross-sectional study was conducted 169 aged 18-55 years using passive knee exten...

Functional adaptations in knee kinematics and kinetics during level walking in 30 patients with unilateral anterior cruciate ligament deficiency and 30 healthy control subjects were studied. To examine the impact of time after injury on the functional adaptations, patients were placed into three time interval groups: early, intermediate, and chronic. The patients with anterior cruciate ligament...

Patients with short congenital amputations below the elbow often function as if they have had a disarticulation of the elbow. We have reviewed the results in six patients who had lengthening of such stumps by the Ilizarov technique to improve the fitting of prostheses. The mean lengthening was 5.6 cm (3.4 to 8.4), and in two patients flexion contractures of the elbows were corrected simultaneou...
