Access to Trauma Care for Patients With Proximal Femur Fractures in Resource‐Limited Settings: A Prospective Cohort Study in Rural Tanzania

open access: yesWorld Journal of Surgery, EarlyView.
The standard of care for proximal femur fractures is internal fixation or arthroplasty within 48 hours after injury. In resource‐limited settings, access to surgical services is limited. The aim of this study was to assess access to care for patients with proximal femur fractures in Tanzania by applying the Three Delays framework.
