Medial tibial pain in runners has traditionally been di agnosed as either a shin splint syndrome or stress fracture. Our work using magnetic resonance imaging suggests that progression of injury can be identified, starting with periosteal edema, then progressive mar row involvement, and ultimately frank cortical Fourteen runners, total 18 sympto matic legs, were evaluated and, within 10 days, referred for radiographs, technetium bone scan, mag netic scan. In 14 the symp tomatic findings cor...

To examine hip abductor strength in long-distance runners with iliotibial band syndrome (ITBS), comparing their injured-limb to nonaffected limb and the limbs of a control group healthy runners; determine whether correction deficits abductors affected through rehabilitation program correlates successful return running.Case series.Stanford University Sports Medicine Clinics.24 distance ITBS (14 female, 10 male) were randomly selected from patients presenting our Runners' Injury Clinic history...

Single-group, repeated-measures design.To compare patellofemoral joint kinematics during weight-bearing and non-weight-bearing knee extension in persons with lateral subluxation of the patella.The only previous study to quantify differences tasks was limited that static loading conditions were utilized. Differences between have not been quantified dynamic movement.Six females a diagnosis pain patella participated. Using kinematic magnetic resonance imaging, axial images obtained as subjects...

Controlled laboratory study using a cross-sectional design.To compare patellofemoral joint kinematics, femoral rotation, and patella rotation between females with pain (PFP) pain-free controls weight-bearing kinematic magnetic resonance imaging.Recently, it has been recognized that malalignment may be the result of motion as opposed to motion.Fifteen PFP 15 ages 18 45 years participated in this study. Kinematic imaging was performed vertically open system. Axial-oblique images were obtained...

Bone stress injury (BSI) represents the inability of bone to withstand repetitive loading, which results in structural fatigue and localized pain tenderness. A BSI occurs along a pathology continuum that begins with reaction, can progress fracture and, ultimately, complete fracture. injuries are source concern long-distance runners, not only because their frequency morbidity they cause but also tendency recur. While most BSIs readily heal following period modified loading progressive return...

Background: The female athlete triad (referred to as the triad) contributes adverse health outcomes, including bone stress injuries (BSIs), in athletes. Guidelines were published 2014 for clinical management of athletes affected by triad. Purpose: This study aimed (1) classify from a collegiate population 16 sports into low-, moderate-, and high-risk categories using Female Athlete Triad Cumulative Risk Assessment score (2) evaluate predictive value risk subsequent BSIs. Study Design: Cohort...

Adolescent females and males participating in running represent a population at high risk of stress fracture. Few investigators have evaluated factors for prospective fracture this population.To better characterize incidence fractures population, we collected baseline factor data on 748 competitive school runners (442 girls 306 boys) using an online survey. We then followed them prospectively the development mean ± SD 2.3 1.2 total seasons cross-country track field; follow-up were available...

Objective To evaluate lifetime prevalence and risk factors for overuse injuries in high school athletes currently participating long‐distance running provide recommendations injury prevention strategies. Design Retrospective study design. Setting Twenty‐eight schools the San Francisco Bay Area. Participants A total of 442 female 306 male athletes, ages 13‐18 years, who are on cross‐country track field teams. Methods Online survey with questions that detailed previous sustained injury. Main...

Objectives: To investigate the association of soccer playing and long-distance running with total regional bone mineral density (BMD). Design: Cross-sectional study. Setting: Academic medical centre. Participants: Elite male players (n = 15), elite runners 15) sedentary controls aged 20–30 years. Main outcome measurements: BMD (g/cm 2 ) lumbar spine (L1–L4), right hip, leg body were assessed by dual-energy x -ray absorptiometry, a scan calcaneus was performed peripheral instantaneous imaging...

Abstract Abnormal patellofemoral joint motion is a possible cause of pain, and patellar braces are thought to alleviate pain by restoring normal kinematics. We evaluated whether females with exhibit abnormal kinematics during dynamic, weight‐bearing knee extension assessed the effects on motion. Real‐time magnetic resonance (MR) images joints 36 female volunteers (13 pain‐free controls, 23 pain) were acquired extension. Pain subjects also imaged while wearing patellar‐stabilizing brace...

Delayed onset of vastus medialis (VM) activity compared with lateralis is a reported cause for patellofemoral pain. The delayed VM in pain patients likely causes an imbalance muscle forces and lateral maltracking the patella; however, evidence relating activation delay to patellar sparse. aim this study was investigate relationship between measures pain-free controls patients.Patellar tilt bisect offset, tracking, correlate classified as maltrackers.Case control study; Level evidence,...

The goals of this study were to review the MRI and sonographic findings in patients diagnosed clinically with high hamstring tendinopathy evaluate efficacy ultrasound-guided corticosteroid injections providing symptomatic relief.MRI is more sensitive than ultrasound detecting peritendinous edema at proximal origin. Fifty percent had improvement lasting longer 1 month after percutaneous injection, 24% symptom relief for 6 months.

Background: Adolescent runners may be at risk for low bone mineral density (BMD) associated with sports participation. Few prior investigations have evaluated health in young runners, particularly males. Purpose: To characterize sex-specific factors BMD adolescent runners. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Training characteristics, fracture history, eating behaviors and attitudes, menstrual history were measured using online questionnaires. A food frequency...
