Intraoperative blood loss during posterior spinal fusion for adolescent idiopathic scoliosis (AIS) has been reportedly associated with multiple factors. This study aims to investigate the effect of thoracic kyphosis on blood loss in AIS spinal fusion. ⋯ Level III-prognostic study.

Children with developmental dysplasia of the hip may require a pelvic osteotomy to treat acetabular dysplasia. Three osteotomies are commonly performed in these patients (Pemberton, Dega, and San Diego), though comparative studies of each are limited. The purpose of this study was to compare changes in acetabular morphology (acetabular version, volume, and octant coverage angles) created by these 3 osteotomies using matched patient-specific 3D-printed pelvic models. ⋯ Quantifiable differences were identified in acetabular octant coverage angles and version between the 3 pelvic osteotomies. San Diego osteotomy increased acetabular coverage posteriorly resulting in acetabular anteversion, whereas Pemberton and Dega had greater superior-anterior coverage resulting in relative acetabular retroversion. This study is the first known to utilize 3D-printed models for comparison of surgical approaches in pediatric pelvic osteotomies.

Controversy exists with regard to the amount of fracture displacement that warrants surgical fixation of medial epicondyle fractures. Inaccurate determination of degree of displacement on plain radiographs may account for the disputed management. Recently, a novel distal humerus axial radiograph technique has been developed to improve the accuracy of radiographs. The purposes of the study are 2-fold; to identify the anatomic orientation of the medial elbow epicondyle physis in children and to compare the accuracy of determining fracture displacement between axial radiographs and standard anterior-posterior (AP) radiographs in a cadaveric medial epicondyle fracture model. ⋯ This study provides further insight into the location and orientation of the medial humeral epicondyle physis, and further supports the improved accuracy of the distal humerus axial radiograph at detecting displacement in medial epicondyle fractures.

Health care in America continues to place more importance on providing value-based medicine. Medicare reimbursements are increasingly being tied to this and future policy changes are expected to reinforce these trends. Recent literature has shown pediatric femur fractures in preschool-age children have equivalent clinical and radiographic outcomes when treated with spica casting or flexible intramedullary nails (IMN). We compared hospital care statistics including charges for nonoperative versus operative treatment for closed femur fractures in 3- to 6-year-olds. ⋯ Level III-retrospective comparative study.

Meta Analysis
Operative Management for Pediatric and Adolescent Scaphoid Nonunions: A Meta-analysis.
Scaphoid fractures in the pediatric population represent ∼3% of all hand and carpal fractures. Cast immobilization has been shown to yield excellent results in the acute phase, however some patients develop nonunions. Currently, there is no consensus regarding the best surgical treatment after development of a pediatric/adolescent scaphoid nonunion. ⋯ Level III. This study is a meta-analysis of studies containing level of evidence of III or greater.
