“…Similar changes involving the inferior patellar pole and proximal patellar tendon are seen with Sinding-Larsen-Johannson disease. For either entity, absence of soft-tissue swelling suggests normal variant rather than overuse injury (143). US of OSD can show pretibial soft-tissue swelling, fragmentation of the ossification center, thickening of recently been identified in pediatric runners and fencers, as well as hockey, soccer, and football players (136,140).…”

“…Cysts at the donor site in juvenile OCD must be multiple or larger than 5 mm to suggest instability (145). In young athletes, one must differentiate OCD from normal variant irregularity of ossification of the posterior femoral condyles, the latter of which has no associated bone marrow edema and is centered posterior to the weight-bearing aspect of the femoral condyle (143).…”

Increased youth participation in sports has resulted in increased injury tolls due to shifts toward participation in competitive sports at earlier ages, increased training intensity and competition schedules, as well as specialization into one sport. The physiology of the growing musculoskeletal system makes the growing athlete particularly vulnerable to specific types of injuries. Radiologists must understand the differences between pediatric and adult athletes to recognize the particular injuries to which these young athletes are prone. Imaging and pertinent clinical details of major representative acute and overuse injuries characteristic to pediatric athletes will be discussed. RSNA, 2017.

“…The difference is that the normal increased signal intensity at the periphery does not extend to the articular surface. 26,27 An important issue refers to fractures involving the distal femur and proximal tibial physes because they can cause abnormal growth if not promptly recognized. They may be subtle on radiograph, requiring MRI to better evaluate their extent and soft tissue injuries.…”

This article reviews acute and chronic lower extremity injuries in children, focusing mainly on those traumas typical of the pediatric population. The child is not just a small version of an adult, so physicians need a very detailed knowledge of the anatomy and physiologic changes occurring during growth to understand and evaluate the mechanism of trauma, and choose the most adequate management. In adolescents the most common lesion encountered affects the physes, which are still open. They predispose to injury as the weakest point in the kinetic chain, so those mechanisms responsible for ligamentous traumas in adults can cause physeal injuries in a skeletally immature patient. In association with them, apophyseal lesions are also very common, leading to avulsion injuries at the site of tendon origin or insertion, also called locus minoris resistentiae. Understanding these types of injuries is essential, specifically for the radiologist, because a missed diagnosis can lead to later complications such as growth arrest and osteoarthritis.

“…In very young pediatric patients, knee MRI is often used to evaluate developmental conditions and nontraumatic pain. 4 In pediatric populations, common injuries are meniscal pathology, cruciate ligament tears, and cartilage abnormalities; these are assessed well with MRI. 1 Despite its advantages, MRI of the pediatric knee presents several challenges due to requirements for high (submillimeter) spatial resolution, leading to lengthy scan and exam times.…”

Background MRI is commonly used to evaluate pediatric musculoskeletal pathologies, but same‐day/near‐term scheduling and short exams remain challenges. Purpose To investigate the feasibility of a targeted rapid pediatric knee MRI exam, with the goal of reducing cost and enabling same‐day MRI access. Study Type A cost effectiveness study done prospectively. Subjects Forty‐seven pediatric patients. Field Strength/Sequence 3T. The 10‐minute protocol was based on T2 Shuffling, a four‐dimensional acquisition and reconstruction of images with variable T2 contrast, and a T1 2D fast spin‐echo (FSE) sequence. A distributed, compressed sensing‐based reconstruction was implemented on a four‐node high‐performance compute cluster and integrated into the clinical workflow. Assessment In an Institutional Review Board‐approved study with informed consent/assent, we implemented a targeted pediatric knee MRI exam for assessing pediatric knee pain. Pediatric patients were subselected for the exam based on insurance plan and clinical indication. Over a 2‐year period, 47 subjects were recruited for the study and 49 MRIs were ordered. Date and time information was recorded for MRI referral, registration, and completion. Image quality was assessed from 0 (nondiagnostic) to 5 (outstanding) by two readers, and consensus was subsequently reached. Statistical Tests A Wilcoxon rank‐sum test assessed the null hypothesis that the targeted exam times compared with conventional knee exam times were unchanged. Results Of the 49 cases, 20 were completed on the same day as exam referral. Median time from registration to exam completion was 18.7 minutes. Median reconstruction time for T2 Shuffling was reduced from 18.9 minutes to 95 seconds using the distributed implementation. Technical fees charged for the targeted exam were one‐third that of the routine clinical knee exam. No subject had to return for additional imaging. Data Conclusion The targeted knee MRI exam is feasible and reduces the imaging time, cost, and barrier to same‐day MRI access for pediatric patients. Level of Evidence: 2 Technical Efficacy: Stage 6 J. Magn. Reson. Imaging 2019.
