INTRODUCTION: Ulnar collateral ligament (UCL) reconstructions are being performed with an increasing annual incidence. The purpose of this study was to evaluate trends in UCL surgery among recently trained orthopaedic surgeons. METHODS: The American Board of Orthopaedic Surgeons (ABOS) database was used to identify all UCL reconstructions from 2004 to 2013. Procedures were identified by Current Procedural Terminology (CPT) codes and verified by International Classification of Disease, Ninth Revision (ICD-9) codes...

Since the loss of balance can result in falls or lower extremity injuries during sports or daily activities, quantitative evaluation of one's ability to maintain balance with changes in the direction of motion is crucial. The present study aimed to assess whether the trajectory length of the center of pressure (COP) and peak values of the ground reaction force (GRF) following a single-leg hop landing differ when hopping forward or laterally, and to ascertain disparities in balance characteristics due to differences in hop direction...

Molecular docking is a powerful technique that helps uncover the structural and energetic bases of the interaction between macromolecules and substrates, endogenous and exogenous ligands, and inhibitors. Moreover, this technique plays a pivotal role in accelerating the screening of large libraries of compounds for drug development purposes. The need to promote community-driven drug development efforts, especially as far as neglected diseases are concerned, calls for user-friendly tools to allow non-expert users to exploit the full potential of molecular docking...

REVIEW
Osnat Hakimi, Luiz-Claudio Cameron
BACKGROUND: Infertility has been described as a devastating life crisis for couples, and has a particularly severe effect on women, in terms of anxiety and depression. Anovulation accounts for around 30% of female infertility, and while lifestyle factors such as physical activity are known to be important, the relationship between exercise and ovulation is multi-factorial and complex, and to date there are no clear recommendations concerning exercise regimes. OBJECTIVES: The objective of this review was to systematically assess the effect of physical activity on ovulation and to discuss the possible mechanisms by which exercise acts to modulate ovulation in reproductive-age women...

BACKGROUND: Patellofemoral pain (PFP) is a prevalent disorder among female adolescents. Overuse is frequently cited as the cause of pain for this population. What is currently unclear, however, is if the patella demonstrates abnormal tracking patterns relative to the femoral trochlear groove in female adolescents with PFP. PURPOSE: The aim of this case-control study was to determine if abnormal patellar tracking patterns are present in female adolescents with PFP...

OBJECTIVES: Females land with more knee valgus than males. While most studies have evaluated lower extremity mechanics during double leg landing, most sports require single-leg landing from a double or single leg takeoff. Further, knee movement occurs toward both varus and valgus during functional landing. The purpose of this study was to determine if differences exist between females and males in total frontal plane movement and velocity of the knee during single-leg landing. DESIGN: Experimental cohort...

The array of dysfunction occurring after ligamentous injury is tied to long-term clinical impairments in functional performance, joint stability, and health-related quality of life. To appropriately treat individuals, and in an attempt to avoid sequelae such as post-traumatic osteoarthritis, investigators have sought to better establish the etiology of the persistent dysfunction present in patients who have sustained joint ligament injuries to the lower extremities. Recent evidence has suggested that changes within the brain and central nervous system may underlie these functional deficits, with support arising from direct neurophysiologic measures of somatosensory dysfunction, motor system excitability, and plasticity of neural networks...

Concussions carry devastating potential for cognitive, neurologic, and socio-emotional disease, but no objective test reliably identifies a concussion and its severity. A variety of neurological insults compromise sound processing, particularly in complex listening environments that place high demands on brain processing. The frequency-following response captures the high computational demands of sound processing with extreme granularity and reliably reveals individual differences. We hypothesize that concussions disrupt these auditory processes, and that the frequency-following response indicates concussion occurrence and severity...

Buckley's commentary on our study of rock climber's withdrawal experiences raises a number of important questions surrounding the concept of extreme or adventure sports addiction. Drawing on the few available investigations of this topic, we respond to Buckley's questions here, though emphasize the need for further studies of extreme sports addiction in order to provide more empirically informed answers.

The article represents a case of a young patient with atypical clinical and paraclinical presentation of vertebral artery dissection by multiple cerebral infarcts, localized at the supratentorial and infratentorial levels in the posterior circulation. A case of a 21-year-old man, without a history of trauma in the cervical area or at the cranial level, without recent chiropractic maneuvers or practicing a sport, which required rapid, extreme, rotational movements of the neck, was examined. He presented to the emergency room with nausea, numbness of the left limbs, dysarthria, and incoordination of walking, with multiple objective signs at the neurological examination, which revealed right vertebral artery subacute dissection after the paraclinical investigations...

The specific demands of a combat-sport discipline may be reflected in the perceptual-motor performance of its athletes. Taekwondo, which emphasizes kicking, might require faster perceptual processing to compensate for longer latencies to initiate lower-limb movements and to give rapid visual feedback for dynamic postural control, while Karate, which emphasizes both striking with the hands and kicking, might require exceptional eye-hand coordination and fast perceptual processing. In samples of 38 Taekwondo athletes (16 females, 22 males; mean age = 19...
