The medical documentation pertaining to 767 victims of traffic accidents was revised. These subjects were classified in the acute post-traumatic period as experiencing serious harm to health in terms of the qualifying sign "substantial persistent loss of at least of one third of general working ability" (SPLGWA) based on the results of primary examination. It was shown that in the course of therapeutic and rehabilitative treatment of the subjects with bone fractures listed in articles 6.11.1, 6.11.2, 6.11.4 to 6.11.10 of the Medical Criteria most of the patients have their compromised functions repaired up to complete recovery of the working ability. According to the repeated evaluation the substantial (35%) loss of the working ability persisted only in 25.8% of the victims. 56.7% of the victims were estimated to have lost 10-30% of their working ability; SPLGWA was absent in 17.5% of the examined subjects.
