Calcaneal fractures Design and clinical application

m. 4 foot bow devices have sliding hole, sliding range of 10ram (see Figure 1) with a wrench,[link widoczny dla zalogowanych], screwdriver and other auxiliary equipment. By adjusting the vertical and horizontal threaded rod nut. To lock needle move, extend or shorten the width of the osseous pin and needle from the device with the bow. 1. Longitudinal bone Kui Pin 2 3 nuts,[link widoczny dla zalogowanych], threaded rod 4. Needle lock screw hole 5 6 7 bow device cross threaded holes 8 holes around pity move in former times the amount of -. 1 Location folded structure of complex surgical procedures around 1.2 after the success of epidural anesthesia, the patient supine on the operating table. Television x-ray machine monitor, in fractures perpendicular to the two ends from the inside out rampant penetration of two calcaneal osseous pin; install bow device and threaded rod and other components; such as the calcaneus with intercalation of two ends, whirl open bow The sliding device foot hole, adjust the nut cross threaded rod. Extend the width of the two osseous pin. Appropriate ends of the bone retractor; adjust vertical threaded rod nut, osseous pin down, with osseous pin and bow under the pressure of the two ends at the fracture line on the device in the force arrived to restore Boh] er angle and ends position (see Figure 2). Reset conditions under fluoroscopic examination, such as the location good. Retention osseous pin, remove the reset control other parts. Fixed-osseous pin (see Figure 3). To maintain the position of the calcaneus after reset. If calcaneal axial broadening, a large number of patients who used the occasion of his hands clasp, squeeze both sides of the heel, while appropriate, the valgus heel, so that consistent fracture fragments in close,[link widoczny dla zalogowanych], then a fixed position with satisfaction. After 3 weeks,[link widoczny dla zalogowanych], 6 weeks, 3 months, six months and taken follow-up x ray examination, Zhu Huanzhe with a needle under the non-weight-bearing activities ankle. According to X-ray findings and the specific circumstances of fractures. 4 weeks osseous pin removed. 8 ~ l2 weeks of weight-bearing walking gradually come down to earth. Clinical data of 1.3 units: Armed Police Corps Hospital of Shandong second surgery. Two liters of Jinan 250101, China: Wang Ruwu (1970.). Male, Taian people, physician. Research Interests: orthopedic trauma and surgery were scattered Tel: (0531) 8985068-4252 (office) l6 cases in this group. Male l3 cases. 3 women down, age 15 - 60 years old, with an average age of 4l. L0 the left side, right 6 down. Falling from height injuries in 11 cases. 3 daily hit back. Traffic accident in 2 cases. Are spread within the subtalar joint fracture, according to Ex-Lo ~ resti classification of fractures of ... sub-l0 foot tongue. Joint compression fracture 6 feet. Bohlea-angle 0. ~ 10'9 cases, l0. ~ 20'7 cases. Calcaneal widening lcm. {Paced walk the line clear of pain, ankle kinetic energy difference. 2,2 Assessment Results were followed up for minimum of 6 months, up to 2 years and 9 October, an average of 125 months. Assessed according to the above criteria, priority l0 down, good in 4 cases and poor in 2 cases. Excellent rate of 875 percent. 3 Discussion 3l reset principle (1) to restore Bohl ~ r angle: vertical threaded rod nut down, so that penetration of the two circular needle in bone fractures under the pressure of the two Sri Lankan side, (set pressure generated by fl,[link widoczny dla zalogowanych], i2). While plantar arch device (arrived at the fracture line in the foot) the force generated on the top of F 'that is: f1 + = F. In this group the role of counterweight to restore Bohler angle. (2) With the occasion of the surgeon fish buckle. Squeeze both sides of the heel. Correct the calcaneal width. 32 Application of the indication that the reset device reset device for fractures and bone fragments in the tongue larger compression fractures; easy to select large blocks of solid fracture pinning position. Large fractures block will reset the whole set of basic OK. Note 3,3 reset operation is slightly bent knees and ankles, so that the Achilles tendon relaxation, hiding the small nodules on the pull with. Solid bow after a reset on the device on the plantar skin, the top pressure. Therefore, the marrow to reset the device. Without extramedullary fixation. . 3.4 The advantages of the application of the instrument needle, reset and other operations carried out only in the calcaneus, across the other joints to avoid reset before power is weak, the treatment does not affect the ankle and other joint activities. Treatment of movement consistent with the principles of fracture. As is co-needle, surgical trauma. And the fracture healed without secondary surgical + needle injection were lower economic costs, safe and convenient. I Fon 2,3 see inset with mother of 2)
