A detailed description of the method and an example of its clinical use are given. This method proved to be effective in treatment of seven patients with deformities of the phalanx of fingers and metacarpal bones. The proposed method of preoperative planning helps the surgeon to perform the intended operation correctly.</p>preoperative planningbone modelpolymeric claycorrective osteotomyphalanx fractureпредоперационное планированиемодель костиполимерная глинакорригирующая остеотомияперелом фаланги[wikipedia.org [интернет].
