Outcomes of dual - mobility cup for displaced femoral neck fractures in the elderly

Femoral neck fracture (FNF) is a common intracapsular fracture in the elderly as a result of osteoporosis, which tends to increase with humans’ extended longevity. Regarding treatment for undisplaced FNF, internal fixation is mostly used, while primary total hip arthroplasty (THA) is used for older patients with displaced FNF because of the high rate of avascular necrosis and nonunion.
