Chapter 5 62 Results Baseline characteristics This pilot study included 150 patients, of whom 68.7% were male, with a median age of 48 years ([IQR 33.0, 57.0], [range: 15-77 years]). The sample included different types of surgically treated (peri)- or intra-articular fractures of the pelvis and lower extremities from the pelvis to the foot. Baseline characteristics are presented in Table 5.2. In all, N=124 (82.7%) of the patients had two or more fractures, and N=19 patients (12.7%) suffered from head injuries. In total, 201 lower extremity fractures were identified, which can be divided into 5 subtypes: pelvic/acetabular (N=76), distal femoral metaphysis or (peri-)articular distal femur (N=42), tibial plateau (N=31), distal tibia/ankle (N=31), and foot (talus, calcaneus) (N=21).

Process outcome measures The median time from fracture surgery to the start of PWB was 2.0 weeks ([IQR 2.0, 3.3], [0-9]). Fifty-two percent of the patients (N=78) reached full weight bearing within 12 weeks. The median time to full weight bearing was 12.0 weeks ([IQR 6.8, 19.2], [2-52]). Table 5.3 specifies for each group of fractures the median and percentage of patients reaching full weight bearing. Patient outcome measures The complication rate during postoperative rehabilitation was 10.0% (N=15) of all patients included. Most complications involved non-unions (N=5), wound infections (N=4) or early removal of implants (N=3) because of pain and/or infection. There was
