Montalti M, et al. - Researchers herein aimed to evaluate the survivorship, the hip score results, the radiological parameters (fixation, loosening, component position) of a large cohort of patients with Crowe III and IV developmental dysplasia of the hip (DDH), treated with a high hip center and modular necks total hip arthroplasties (THAs). In DDH patients, a high cup placement with slight medialization was noted to be a valid technique. Overcoming the effects of increasing joint reaction forces related to high cup placement, a good restoration of the offset, ceramic-on-ceramic coupling and a porous socket could provide durable results.
