Diagnosis of Developmental Dysplasia of the Hip by Ultrasound Imaging Using Deep Learning.

Background: A timely diagnosis of developmental dysplasia of the hip (DDH) is important for satisfactory clinical outcomes. Ultrasonography is a useful tool for DDH screening; however, it is technically demanding. We hypothesized that deep learning could assist in the diagnosis of DDH.

Complications of Posterior Fusion for Atlantoaxial Instability in Children With Down Syndrome.

Objective: To clarify the complications of posterior fusion for atlantoaxial instability (AAI) in children with Down syndrome and to discuss the significance of surgical intervention.

Methods: Twenty pediatric patients with Down syndrome underwent posterior fusion for AAI between February 2000 and September 2018 (age, 6.1 ± 1.

The predictive value of synovial glucose level in septic arthritis.

The aim of this study was to investigate the ability of the joint fluid glucose level to detect septic arthritis. Thirty joints in 30 patients with suspected septic arthritis were evaluated. When glucose level was less than 40 mg/dl, we performed arthrotomy.

Treatment for unstable slipped capital femoral epiphysis: Current status and future challenge in Japan.

Background: Treatment for unstable slipped capital femoral epiphysis (SCFE) is challenging and controversial. For many years, the debate centered around closed treatments and especially the pros and cons of manual reduction and its concrete procedure. However, recent studies reported on open treatments such as open reduction through an anterior approach and modified Dunn procedure.

A new predictive indicator by arthrography for future acetabular growth following conservative treatment of developmental dysplasia of the hip.

The aim of this study was to find a new predictive indicator for acetabular growth of developmental dysplasia of the hip. Seventy-three hips that were diagnosed with developmental dysplasia of the hip and treated by conservative reduction were included in our study. In 30 hips with center-edge angle ≤ 10° at age 4, the center-edge of the acetabular limbus angle (CEALA) in the arthrogram was measured.
