Slipped capital femoral epiphysis (SCFE) is a common hip disorder in adolescents that can result substantial complications, impacting the quality of life. Human Growth Hormone (HGH) administration may elevate risk SCFE, though relationship remains unclear. Clarifying this association could enable better monitoring and earlier diagnosis SCFE patients receiving HGH. The aim study to investigate between HGH incidence SCFE.

Clubfoot is at times associated with other lower extremity abnormalities, such as leg length discrepancy (LLD). Initial studies in patients treated extensive soft tissue release (STR) have estimated that LLD prevalent 9% to 11% of children idiopathic clubfoot. However, Ponseti-style serial casting has since replaced STR the preferred clubfoot treatment method. This study aimed assess prevalence LLD, risk factors for and required deformity after Ponseti casting. A retrospective review medical...

Despite the high rate of initial success using Ponseti method to manage idiopathic clubfoot deformity, relapse continues be a problem. We surveyed Pediatric Orthopedic Society North America (POSNA) members about their experience with relapsed deformity following correction clubfeet.We created survey focus on management clubfeet after deformity. The included questions postcorrective bracing, clinical findings used identify relapse, observed frequency and how relapses are managed....

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