Chapter 5 50 Abstract Introduction To optimize rapid clinical recovery and the restoration of function and functionality, permissive weight bearing (PWB) has been designed as a new aftercare mobilization regimen, within the upper boundary of the therapeutic bandwidth, yet safe enough to avoid overloading. The aim of the present paper is to describe a comprehensive protocol for PWB during allied health therapy and to report on the time to full weight bearing as well as the number of complications in patients with surgically treated fractures of the pelvis and lower extremities undergoing PWB. Patients and methods This study included surgically treated trauma patients with (peri)- or intra-articular fractures of the pelvis and lower extremities. A standardized PWB protocol was used for all patients. Time to full weight bearing and number of complications were recorded. Results This study included 150 patients, 69% male, with a median age of 48 years (IQR 33.0, 57.0). The median time to full weight bearing was 12.0 weeks (IQR 6.8, 19.2). The complication rate during rehabilitation was 10%. Conclusion The PWB protocol, as described, might be beneficial and has potential to be implemented in trauma patients with surgically treated (peri)- or intra-articular fractures of the pelvis and lower extremities.
