Septic arthritis, a surgical emergency, is always to be suspected when a child of any age presents with hip pain, fever, irritability and toxic appearance without a history of trauma. In this setting, the differential can vary from relatively harmless conditions like transient synovitis to life threatening septic arthritis, which is the most dreaded possibility requiring a swift diagnosis to avoid destruction of the articular cartilage and reduce the risk of developing early arthritis.

Three per cent of LHNAs that had >10° error resulted from 10° LHNA error additional three-dimensional imaging should be considered. Of those, 70% had 10° of error from the actual SW angle.

Seventy-six per cent of all imaging position-deformity combinations had error in the reported angle (>1° difference between LHNA and SW). Femoral lateral head-neck angles (LHNA equivalent to SW in incorrect frog-lateral plane) were measured over a range of 837 incorrect frog-lateral leg positions with positioning errors in flexion and/or internal/external rotation. SW angles were measured from a simulated frog-lateral position. Models of SCFE hips were produced from one CT scan of a normal hip 360 deformities were created. The purpose of this study is to determine how errors in frog-lateral radiograph positioning affect measured SW angles and slip classifications. The SW angle is measured in the frog-lateral leg position, which can be painful and potentially unattainable for patients. Appropriate treatment of SCFE depends on the severity of the slip, commonly categorised using the Southwick (SW) angle. Slipped capital femoral epiphysis (SCFE) is a hip disorder where the femoral head slips relative to the neck at the physis.
