The unstable slipped capital femoral epiphysis: does the rate of osteonecrosis really depend on the timing of surgery and surgical technique?

The aim of this study was to investigate whether the timing of surgery and surgical technique affect the rate of osteonecrosis in unstable slipped capital femoral epiphysis (SCFE). This is a retrospective review of all unstable slips that were treated at our institution over 8.5 years with a minimum follow-up period of 12 months.

Radiologically defining horizontal gaze using EOS imaging-a prospective study of healthy subjects and a retrospective audit.

Background Context: As sagittal alignment of the cervical spine is important for maintaining horizontal gaze, it is important to determine the former for surgical correction. However, horizontal gaze remains poorly-defined from a radiological point of view.

Purpose: The objective of this study was to establish radiological criteria to define horizontal gaze.
