Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, particularly to orthopaedics, and can be used for surgical treatment of non-normal hammer-like deformities of the second toe. Using a full-scale foot X-ray image, parameters are determined to eliminate foot deformation. First, a line of the longitudinal axis of the second instep bone is applied, and perpendicular to this line is drawn through the distal end point of the distal epiphysis of the second instep bone. That is followed by accessing the level of the prospective osteotomy, selecting a diaphysis of the second instep bone and performing osteotomy according to the specified parameters, deviating from the neck of the second instep bone in proximal 10 mm. Second perpendicular to the longitudinal axis of the second instep bone is drawn through the distal end of the distal epiphysis of the third instep bone. Distance between the first and second perpendiculars at extreme points is measured on the line of the longitudinal axis of the second instep bone, subtracting from obtained value 2 mm; the remaining distance is the length of the required shortening of the second instep bone. Then in the distal portion of the second instep bone, a first osteotomy line is made perpendicular to the longitudinal axis of the second instep bone, followed by a second osteotomy line parallel to the first osteotomy line, the distance from the first osteotomy line being equal to the length of the required shortening of the second instep bone. First osteotomy at angle of 80 degrees to its horizontal axis from a back to a plantar surface of a metatarsal bone in a distal direction is performed along the planned lines in a frontal plane. Osteotomized fragments of the metatarsal bone are bred, after which the second osteotomy is performed along the planned line parallel to the plane of the first osteotomy. Obtained free bone fragment is removed, the ends of the proximal and distal fragments of the second instep bone are compared. Compression along bone axis is performed until fragments fully contact and fixed. 
     EFFECT: method provides more accurate correction of second finger deformation, optimal distribution of load on head of metatarsal bones, restoration of motions in metatarsophalangeal joint and statodynamic function of foot, elimination of pain syndrome due to preliminary calculation of the required shortening of the second metatarsal bone on the X-ray image taking into account individual peculiarities of the foot condition of the patient, and a row of the third metatarsal bone.

Abstract: Изобретение относится к полигонным испытаниям осколочных боевых частей подрывом в щитовой мишенной обстановке, выполненной из листового материала в виде плоского вертикального щита, а именно для экспериментального определения координат пробоин в щите и начальных скоростей поражающих элементов, включая экваториальные и меридиональные углы их разлета. Способ состоит в том, что со щитом, размеченным на пронумерованные прямоугольные клетки, связывают прямоугольную систему координат OXYZ, боевую часть устанавливают с известными координатами ее центра в системе координат щита, направляя поток поражающих элементов на щит. Процесс пробития щита поражающими элементами регистрируют скоростной цифровой видеокамерой со стороны разметки. После испытания, каждую клетку щита с пробоинами фотографируют цифровым фотоаппаратом. В компьютерной среде на каждой фотографии измеряют координаты четырех углов клеток - опорных точек - и вычисляют элементы ориентирования фотографий. На каждой фотографии измеряют координаты геометрических центров пробоин и вычисляют координаты этих точек в системе координат щита OXYZ. На одном из цифровых кадров высокоскоростной видеокамеры измеряют координаты любых четырех углов клеток - опорных точек - и вычисляют элементы ориентирования кадров. Координаты геометрических центров пробоин из системы координат щита OXYZ пересчитывают в координаты на кадрах скоростных видеокамер. Указав координаты пробоины в системе координат кадров, просматривают фрагменты кадров в окрестности этой пробоины и фиксируют время между началом отсчета времени и вспышкой при пробитии щита поражающим элементом. При этом пробоины и соответствующие им вспышки идентифицируют по взаимному расположению вспышек на фрагментах кадров и взаимному расположению пробоин на фрагменте диаграммы рассеивания пробоин в системе координат кадров в окрестностях одинакового размера. По координатам центров пробоин в системе координат щита OXYZ, известным координатам боевой части в системе координат щита OXYZ и зафиксированным моментам времени вычисляют средние скорости и баллистические коэффициенты каждого поражающего элемента, а по этим значениям - модули начальных скоростей каждого поражающего элемента, а также экваториальные (θ) и меридиональные (ϕ) углы по формулам. Технический результат заявленного изобретения заключается в повышении информативности полигонных испытаний осколочных боевых частей при увеличении точности измерений начальных скоростей поражающих элементов и исключении потери или приобретения ложных данных о пробитии щита поражающими элементами. 6 ил.
