The Impact of Radiographic Lower Limb-Spinal Length Proportion on Whole-Body Sagittal Alignment.

Study Design: A radiographic comparative study.

Objective: To investigate the influence of radiographic lower limb-spinal length proportion on sagittal radiographic parameters.

Summary Of Background Data: Although lordotic realignment of the lumbar spine is a well-established surgical strategy, its ideal target has not been fully understood.

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.
