Jessica R Leschied, Kara Gaetke Udager
The knee joint is commonly injured in the young athlete. This article discusses the common injury patterns around the knee that are unique to this patient population. Pediatric patients have relative weak points at their physes and apophyses that result in different forces on ligaments and bones during injury compared with adults. Common pathologic findings seen on imaging include patellar and patellar tendon injury, physeal fractures, osteochondral abnormality, ligament tears, and meniscal injury. Imaging studies are also performed to evaluate pediatric patients after surgical knee injury repair, and radiologists should be familiar with certain pediatric-specific knee repair techniques and their imaging appearances...

BACKGROUND: Obesity as a cause of lower extremity deformity in children has been well established. This deformity is most often seen as tibia vara, however, at our institution we have observed more obese children and adolescents over age 7 years with excessive or progressive idiopathic genu valgum. Our hypothesis is that children with idiopathic genu valgum have high rates of obesity which impact the severity of their disease. METHODS: Retrospective review of existing data was performed on 66 consecutive children/112 limbs over age 7 years with idiopathic genu valgum, seen from 2010 to 2013...

An adolescent obese boy showed late-onset unilateral tibia vara associated with physeal separation (slipped epiphysis) of the lateral proximal tibia and physeal widening of the lateral distal femur. These affected physes showed normal signal intensities by MRI. He was treated with lateral hemiepiphysiodesis of the left proximal tibia and the distal femur using two parallel eight-Plates, and varus deformity rapidly improved postoperatively without recurrence. This is the first case of late-onset tibia vara caused by lateral physeal separation of the proximal tibia...

Lameness related to growth plate lesions is an important problem in the beef industry. This article describes the macroscopic and microscopic lesions in the distal metatarsal physis of bulls from an association of farmers in northeastern Italy. The metatarsal bones of 62 bulls (12 with severe lameness and 50 without lameness), average age 16.44 ± 1.72 months, were examined at the abattoir. The animals came from the same geographic area and shared intensive husbandry practices and a diet based on maize starch...

The etiology remains unclear. Mechanical factors seem to play an important role. Most histologies report clefts between the cartilage and bone and necrotic areas. Several classifications have been published based on observations from imaging techniques or on intraoperative findings. Clinical symptoms are unspecific. Imaging techniques are of great importance: X-rays of the ankle joint enable a quick diagnostic overview. MRT is the imaging-technique of choice for diagnosing OCDT-lesions. Regarding treatment, a tremendous number of retrospective publications exist...

CASE HISTORY: A group of 545 pregnant rising 2-year-old Coopdale ewes on a Southland sheep farm were grazed over winter on a fodder beet (Beta vulgaris) crop. Subsequently, 45 out of approximately 750 lambs were born with a variety of skeletal deformities, including shortened limbs, varus and valgus angular limb deformities, palmar grade stance and cranial bowing of the carpus. Analysis of the crop showed the fodder beet contained a low percentage of phosphorus. In addition, 60 out of 460 rising 2-year-old ewes that had been grazed on the fodder beet crop as 1-year-olds had incisor abnormalities and malocclusion...

REVIEW
Andrew Pennock, Michael M Murphy, Mark Wu
The management of pediatric patients with an anterior cruciate ligament (ACL) tear can be a challenging endeavor for physicians, athletic trainers, coaches, and parents alike. In particular, the significant longitudinal growth that arises from the physes about the knee creates a unique set of circumstances that must be considered in this patient population. The purpose of this review is to provide a summary of the most recent current literature for the management of skeletally immature patients with an ACL tear...
