Partial weight bearing is a generally accepted principle of rehabilitation following trauma or reconstructive surgery of the lo-wer extremity. Individual dynamic loads during partial weight bearing to a given load level of 200 N were compared in 23 patients who had sustained a fracture of the lower extremity and 11 healthy volunteers using dynamic sole pressure measurements. Excessive dynamic loading compared with the statically pre-tested 200 N level was observed in all groups. Maximum force levels were up to 690 N in young patients and up to 580 N elderly patients beyond the prescribed static load. None of the healthy volunteers was able to keep within the given load of 200 N. The set load level was exceeded by at least 38 N (119%) in the elderly patient group. In com-parison, elderly patients showed statistically significantly higher maximum forces than young patients during the first two test days (p = 0.007 and 0.013). On the 3rd test day the maximum ground contact forces were on average 71 N higher than in the young patients group. Analysis of the force time integrals (impulses transferred to the ground) displayed higher values in the older again than in young patients. The differences were statistically significant during the first two test days (p = 0.006 and 0.037). This study implies that the conventional concept of postoperative partial weight bearing starting from 200 N and a stepwise in-crease of the load level until full weight bearing is not valid during clinical practice.
