Deformity angular ratio is associated with neuromonitoring changes without a vertebral column resection: spinal deformity is more influential than type of surgery.

Purpose: The purpose of this study is to investigate the effect of the deformity angular ratio (DAR) on intra-operative neuromonitoring (IONM) signal changes during posterior spinal fusion (PSF) without vertebral column resection (VCR).

Methods: Retrospective review of severe pediatric spinal deformity patients treated with PSF without VCR or three-column osteotomy from 2008 to 2018. Exclusion criteria were prior instrumentation, lack of IONM, and incomplete radiographic data.

Exposed Intramedullary Fixation Produces Similar Outcomes to Buried Fixation for Acute Pediatric Monteggia Fractures.

Background: Treatment of acute pediatric Monteggia fractures requires ulnar length stability to maintain reduction of the radiocapitellar joint. When operative care is indicated, intramedullary ulna fixation can be buried or left temporarily exposed through the skin while under a cast. The authors hypothesized that treatment with exposed fixation yields equivalent results to buried fixation for Monteggia fractures while avoiding secondary surgery for hardware removal.

Adolescent idiopathic scoliosis patients treated with bracing, surgery, or observation showed no difference in behavioral and emotional function over a 2-year period.

The purpose of this study was to assess if behavior and emotional function, as measured by the Pearson Behavioral Assessment Survey for Children, Second Edition (BASC-2) in patients and parents, changes with differing treatment protocols in patients with adolescent idiopathic scoliosis (AIS). One previous study showed abnormal BASC-2 scores in a substantial number of patients diagnosed with AIS; however, no study has assessed how these scores change over the course of treatment. AIS patients aged 12 to 21 years completed the BASC-2.

Gait Analysis Characteristics in Relapsed Clubfoot.

Background: Relapse rates of clubfoot deformity after initial correction range between 19% and 68% regardless of treatment approach. Most studies focus on relapse before age 4. Little research has focused on late clubfoot relapse.
