What this Trial Is About
Researchers are evaluating the best rehabilitation method for patients who have suffered Displaced Intra-articular Calcaneal Fractures (DIACFs), which are fractures involving the heel bone often requiring surgery. This study aims to compare two rehabilitation protocols: Permissive Weight Bearing (PWB) and Restricted Weight Bearing (RWB), focusing on functional outcomes, quality of life, radiographic differences, cost-effectiveness, and complications. The trial is a multi-center randomized controlled study involving patients aged 18 to 67 years who have undergone surgical fixation for DIACFs.
Participants are randomly assigned to one of two rehabilitation groups. The PWB group starts weight bearing about two weeks post-surgery after wound healing, progressing according to patient comfort and pain with guidance from therapists and physicians. They follow milestones such as walking with crutches or canes with recordings of progress. The RWB group follows standard AO guidelines with 8 to 12 weeks of minimal weight bearing (0-10%), gradually increasing weight bearing by 25% weekly after 8 weeks. Both protocols include detailed records of weight bearing advice throughout treatment.
During the study, participants will be assessed at 0, 2, 6, 12 weeks, and 6 months after surgery. Researchers will measure functional outcomes using the AOFAS questionnaire, foot function scores, daily living activities, quality of life surveys, and radiographic parameters like Böhler's angle. Costs and complications will also be tracked. Follow-up visits align with current trauma guidelines and include clinical evaluations and imaging, with radiation exposure consistent with standard care. The total study duration allows for comprehensive monitoring of recovery and rehabilitation effects.
