[Self-mutilating hand and finger injuries among physicians suspected of insurance fraud].

27 cases of questionable self-mutilation among physicians (concerning finger and hand injuries) were analyzed retrospectively. The evaluation based on files of the insurance companies, reconstructive examinations and experimental investigations. Three typical cases are described in detail, the "victims" were suspected to have committed a special kind of fraud in order to claim financial compensation from their accident-insurance companies; the contract included special invalidity payments for finger injures (so-called "Gliedertaxe"). Many of these physicians had worked in the surgical field: apart from one 38-year-old female all of them were males, aged between 41 and 66 years. The mutilating instruments were often circular saws, sometimes chain saws and a great variety of other tools, for example hatchet, big scissors and other sharp instruments. By means of forensic-medical expertise and criminalistic investigations the insurance companies were able to demonstrate clearly that the amputation was voluntarily self-inflicted. The forensic-medical argumentation concerning intentional self-mutilation included the so-called execution position of the finger, the injury pattern, the investigations of blood stains and ergonometric aspects.
