A method for producing a defined bone fracture with accompanying soft tissue injuries in a specimen comprising bone and soft tissue envelope, wherein for carrying out the method, use is made of an apparatus, which comprises i. at least one guide column,, ii. at one end of the guide column, a base plate,, iii. a traverse, with impact punch,, iv. at least one means for adjusting the damping during the impact of the defined mass,, v. at least one clamping plate, for fixing the specimen, vi. a mass, and optionally an additional weight, for adjusting a defined mass, vii. at least one further traverse, with at least one releasable holding mechanism, for positioning the defined mass and means for fixing the specimen, wherein a) the defined bone fracture is a distal radius fracture, b) a specimen comprising or consisting of hand, forearm and upper arm is selected, c) a defined mass of 16.6 to 23.1 kg is adjusted, d) the specimen is orientated in a defined geometry with respect to the direction from which the defined mass impacts with the specimen when the holding mechanism, is released, with the aid of means for fixing the specimen, wherein the cut surface of the humerus is positioned centrally under the point of attack of the force, the humeroulnar joint is flexed from maximum extension by 0 to 12 degrees, in this position the forearm is rotated from maximum supination to pronation of 45 to 70 degrees; e) a defined speed at which the defined mass impacts with the specimen when the holding mechanism is released is adjusted to 76 to 110 cm by means of the falling height of the defined mass, f) a defined compression to which the specimen is exposed upon impact of the defined mass when the holding mechanism is released is adjusted to 20 to 36 mm by means for adjusting the damping during the impact of the mass,, g) a defined damping with which the defined mass is braked upon impact with the specimen when the holding mechanism is released is adjusted to 5 to 17 mm as the damped portion of the defined compression, h) the holding mechanism, is released, i) the specimen is removed from the apparatus,. i. at least one guide column,, ii. at one end of the guide column, a base plate,, iii. a traverse, with impact punch,, iv. at least one means for adjusting the damping during the impact of the defined mass,, v. at least one clamping plate, for fixing the specimen, vi. a mass, and optionally an additional weight, for adjusting a defined mass, vii. at least one further traverse, with at least one releasable holding mechanism, for positioning the defined mass and means for fixing the specimen, a) the defined bone fracture is a distal radius fracture, b) a specimen comprising or consisting of hand, forearm and upper arm is selected, c) a defined mass of 16.6 to 23.1 kg is adjusted, d) the specimen is orientated in a defined geometry with respect to the direction from which the defined mass impacts with the specimen when the holding mechanism, is released, with the aid of means for fixing the specimen, wherein the cut surface of the humerus is positioned centrally under the point of attack of the force, the humeroulnar joint is flexed from maximum extension by 0 to 12 degrees, in this position the forearm is rotated from maximum supination to pronation of 45 to 70 degrees; e) a defined speed at which the defined mass impacts with the specimen when the holding mechanism is released is adjusted to 76 to 110 cm by means of the falling height of the defined mass, f) a defined compression to which the specimen is exposed upon impact of the defined mass when the holding mechanism is released is adjusted to 20 to 36 mm by means for adjusting the damping during the impact of the mass,, g) a defined damping with which the defined mass is braked upon impact with the specimen when the holding mechanism is released is adjusted to 5 to 17 mm as the damped portion of the defined compression, h) the holding mechanism, is released, i) the specimen is removed from the apparatus,.
