Hammer-like deformation of fingers is most often the result of a patient’s injury – a closed tear-off fracture of the base of the back fragment of the distal phalanx. In the treatment of this pathology since the late eighties of the twentieth century, Ishiguro blocking osteosynthesis has been successfully applied. The authors developed and applied in clinical practice a method of compression-blocking osteosynthesis. The article presents a comparative analysis of blocking and compression-blocking osteosynthesis performed in 15 patients aged from 11 to 57 years who had tear fractures of 16 fingers and applied for help to the republican center of hand surgery, operating on the basis of the 6th city clinical Minsk hospitals. Ishiguro blocking osteosynthesis was performed in eight observations (on nine fingers), compression-blocking osteosynthesis, the method of implementation of which is illustrated with diagrams and radiographs, was performed in seven cases. All patients studied using the Russian version of the DASH questionnaire received excellent and good results of surgical treatment. The best anatomical and functional results of operations (six of seven) were achieved after performing compression-blocking osteosynthesis.
