Method of treating chronic osteomyelitis of long bones

Method of treating chronic osteomyelitis of long bones

All sclerotic changed endosseous bone tissues are excised outside a sanitised osteomyelitic region from the inside through a sequestral bone defect up to a support cortical layer, wherein the porous structure of bone tissue is formed by forming microperforations from the intramedullary bone cavity throughout the sclerotic changes within the periosteum. All the microperforations and sequestral bone defect in the cortical layer is filled with intraoperatively hardening bactericidal osteogenic bone-plastic material. The left intramedullary bone defect is repaired later at the moment of granulation tissue maturation in the bone wound by introducing the X-ray controlled osteogenic bactericidal bone-plastic material through one of two drain tubes.

Device for correction of displaced cervical articular process positions and method for using it

Device for correction of displaced cervical articular process positions and method for using it

Device for the correction of displaced cervical articular process positions comprises a composite body of a head and a cylindrical base, upper and lower supporting platforms, outer surfaces of which face the vertebral bodies and have pointed flanges. The upper supporting platform is mounted on the head of the composite body. The upper portion of the base comprises a T-flange, projection sides of which are guides for female grooves mounted in the lower portions of the head. The head and base are connected by a thread rod having smooth ends, a diameter of which is less than the diameter of the middle thread portion of the rod. One end of the rod is provided with a closed hole for a box spanner, is mounted in a transfer sleeve having a thread along the outer side surface and a slot at the end face. The sleeved rod is mounted in a through hole in the composite body perpendicular to its long axis. The threaded sleeve thread is created in the hole only in the portion of the base, while the thread of the middle of the threaded rod - on the portion of the head of the composite body. The device also comprises an end plate that can be detachably laid on the head of the composite body The upper surface of the above plate has a horizontal portion with notches inserted into the vertebral body at the side of the dislocation, while two adjacent smooth portions inclined at various angles are mounted on the side of the intact articular process. The lower supporting platform having four diametrical vertical notches on the side surface is integrated with vertical and central threaded rod having four long grooves, a position of which corresponds to the position of the above notches, and a recess on the free end. A cup with a through hole in the middle provided with a long projection is formed on the rod; the hole has the shape and size corresponding to the long grooves on the rod; the notch of the side surface is coaxial with the flange in the hole on the vertical threaded rod. The cup bottom comprises a nut having radical through holes along the mid-line of the outer surface. The vertical rod with the mounted nut is mounted in a step cylindrical cavity arranged axially in the cylindrical base of the composite body. The nut is provided in the cavity with the greater diameter open to the bottom of the cylindrical base. Along the outer surface of the bottom of the base and the inner surface of the cup, there is a thread used to flush connect these parts along the outer surface of the cup and base. There is a window formed from the cup bottom to the height of the nut by the surface section at the mid-diameter. The upper portion of the head comprises a T-flange identical to that on the base of the composite body, side flanges of which are guides for the female grooves mounted in the lower portions of the end plate. Along the inner horizontal surface of the plate, above the grooves, there is a rectangular hollow for mounting the upper supporting platform. Two thread holes for a retainer are created along the side surfaces of the base of the body, and one - along the front surface of the end plate under the horizontal flange. A method for the correction of displaced cervical articular process positions involves placing the patient on a table in the lying position with a roller placed under his/her shoulders under general anaesthesia, performing a standard approach to anterior structures of the vertebral body under its dislocated or fractured body with removing super- and subjacent disks and bone fragments. The above device is laid into the formed compartment. The end plate is laid on the head of the composite body; the angles on the upper surface of the plate shall correspond to the fracture nature, right- or left-sided, of a different height and length so that the upper horizontal platform of the end plate is arranged on the side of the dislocation close to the articular processes of the vertebrae, while its inclined surfaces faces the intact articular process. The nut is rotated with a special instrument, and a working end is alternatively inserted into radial surfaces to lift the composite body in relation to the lower supporting platform. That is followed by performing distraction until translation of the body along the vertical threaded rod along the lower supporting platform is blocked. The device is rotated with the instrument mounted into the holes on the side surfaces of the body. Geared articular processes of the vertebrae are disconnected by EOP control according to pre-calculated CT or visual data, the base is kept to be rotated until the flange on the cup bottom falls into the long groove on the vertical threaded rod. The distraction is reduced by rotating the nut backwards to place the dislocated articular process back into its physiological position. The distraction is kept to be released to enable removing the end plate with an instrument freely. Tension in the vertebral compartment with the installed device is created by generating slight distraction. The device is remained installed in the bed as a body-substitute implant. Layered sutures are applied.

Method for olecranon osteosynthesis

Olecranon setting controlled by the intraoperative electron-optical image converter is followed by inserting two parallel pins with using a single-toothed hook through an apex of the olecranon with fixing a fracture area towards the elbow crest in an upper one-third of a forearm in the distal direction from the fracture line and percutaneously brought on a posterior surface of the forearm. A control X-ray examination is followed by hooking proximal ends of the pins forward and inserting into the olecranon apex through skin punctures made by a scalpel. That is followed by a one-stage compression of the fracture area through the skin punctures of the pin exit points on a posterior surface of the forearm by pulling the parallel pins up. K-wires are hooked in the posterior direction and cut off. The ends of the cut-off pins are arranged above the skin surface. The opposite direction of the pin hooking on both ends prevents a possibility of migration. The postoperative period involves the plaster immobilization of an upper limb with fixing the elbow and carpal joints.

Method for anatomic surgical simulation of external rotational hip contracture experimentally

Method for anatomic surgical simulation of external rotational hip contracture experimentally

Hip joint of Kocher-Langenbeck type is posteriorly approached on an unclaimed corpse. External hip rotators are separated from an anatomic attachment to the hip. Femoral head and neck, and edges of a cotyloid cavity are exposed. A guide pin locating a plane line of an entry into a cotyloid cavity in a horizontal section of the hip joint is laid. That is followed by an osteotomy of the femoral neck and head in the horizontal plane. The guide pin is delivered through an apex base of a greater trochanter in the direction from the outside inwards along a long axis of the femoral neck and head along the horizontal plane of the osteotomised femoral head and neck up to a subchondral medial edge of the femoral head. A horizontal hip inclination angle is simulated with a lower limb with a knee bent at 45° by hip rotation with internal ankle rotation so that a measured crossing angle of the guide pins is 56°. The shortened external hip rotations are simulated by a temporary fixation of the external hip rotators to the anatomic attachment in a trochanteric fossa at the horizontal hip inclination angle of 56° with a negligible tension of the external hip rotators. It is predicted to correspond to the degree 1 external rotational hip contracture. That is followed by similar actions with the horizontal hip inclination angle of 46° that corresponds to the degree 2 external rotational hip contracture. The horizontal hip inclination angle of 36° corresponds to the degree 3 external rotational hip contracture.

Method of treating proximal femur deformities

Method of treating proximal femur deformities

Pelvic X-ray pattern is formed in an anteroposterior projection. An anatomical axis of femur, a centre of a femoral head, a vertical inclination angle of a cotyloid avity (Sharp angle) are localised. The femur is disintegrated by transtrochantic C-osteotomy. A transosseous device is used to move and fixe to correct the collum-epiphyseal and collum-diaphyseal deformities, to recover a femoral neck length. Depending on a degree of misalignment of the femoral head in relation to the cavity determined by the relation of the Sharp angle and an angle formed by a horizontal and a transverse angle of the femoral head, the X-ray pattern is used to calculate a centre and a rotation angle of the proximal bone fragment. Taking into account the rotation angle of the proximal bone fragment, a radius of the femoral head, a relation of an apex of the greater trochanter and the centre of the femoral head, an optimum location of the greater trochanter in relation to the femoral head providing the femoral neck shortening is determined. A direction and a value of the distal bone fragment displacement are determined.

Method for closed reduction of fractures of surgical neck of humerus with osteosynthesis with strained nail bundle

Method for closed reduction of fractures of surgical neck of humerus with osteosynthesis with strained nail bundle

Invention refers to medicine, namely traumatology and orthopaedics and is intended for a closed reduction of fractures of the surgical neck of the humerus. A patient is anaesthetised. A kind of an adduction fracture of the surgical neck of the humerus, as well as a lateral or medial dislocation of the humeral diaphysis is determined. The dislocation is typed if observing the humeral dislocation in a combination with the fracture. Preliminary myorelaxation is followed by manual or countertraction reposition of the detached head into the humeral joint to evaluate a relation of the head of the humerus to the distal portion of the humerus under electronic-optical control. The curved cannulated awl inserted through a 3-4 mm skin incision along the external posterior surface of the lateral condyle of the humerus is used to form the condylar canal towards the bone marrow canal of the humerus. A strained fixation nail is inserted into the bone marrow canal of the humerus through the formed canal and through the formed skin punctures along the inferior-exterior posterior surface of the external condyle of the humerus outside of the elbow joint to the fracture line. Each individual fixation nail of 2 mm in diameter is inserted by rotation. Ten rods and Ender rods in a quantity of 5 to 8 are used as the strained flexible fixation nails. The required quantity of the strained fixation nails is inserted to form a nail bundle. That involves using the fixation nails with the ends bent at an angle of 25-30°C at 30-40 mm from a sharp edge. The bent ends of the fixation nails inserted to the fracture line are turned in opposite directions to form a fan of the strained nails. A percutaneous reposition device is inserted through the skin puncture between the fragments and used to eliminate the edgewise dislocation of the diaphysis, as well as to eliminate its rotational and angular dislocations. The fixation nails pre-arranged to the fracture line are driven into the head of the humerus to touch its internal cortical layer. The fixation nails projecting from the condyle are cut off leaving the 2-3-mm ends. The surgery is terminated by applying one suture on the skin in a place of insertion of the fixation nails and conducting antibacterial therapy for 4-5 days. The post-operative patient management involves an active workout of the humeral and elbow joints 2-3 days after post-traumatic pain syndrome relief with the exercises done 3-4 times a day until the operative upper extremity function is completely recovered.
