ABSTRACT
<p><b>OBJECTIVE</b>To analyze the curative effects and feasibility of the self regulating simple localizer through anterior approach for the treatment of odontoid fracture in adults.</p><p><b>METHODS</b>From June 2010 and December 2012, 6 patients with odontoid fracture underwent an anterior operation using a single hollow screw located by the self regulating simple localizer. There were 4 males and 2 females, aged from 28 to 55 years old with an average of 39.1 years. The injuries were caused by traffic accidents in 4 cases and falling injury from high in 2 cases. According to the classification of Anderson, 4 cases were type II and 2 cases were simple type III. All the patients underwent operations in 5 to7 days after injury with the mean of 5.9 days. None of the patients had a spinal cord injury. The safety and feasibility of the self made localizer were observed in follow up for fracture healing and clinical effects.</p><p><b>RESULTS</b>All the operations were successful with an average time of 50 min (ranged from 45 to 55 min) and the mean bleeding volume was 25 ml(ranged from 20 to 30 ml). No injuries of esophagus, trachea or nerve were found. All the patients were followed up from 8 to 16 months and all fractures were obtained bone healing. The flexion extension radiograph showed a well stability of atlantoaxial joint in last followed up.</p><p><b>CONCLUSIONS</b>The self regulating simple localizer is a minimally invasive, short time and safe method in treating odontoid fractures through anterior operation with hollow screw. It may be a reliable choice while without a professional localizer.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the clinical effects of external fixator in treating comminuted fracture of distal radius.</p><p><b>METHODS</b>From Mar.2008 to Dec.2009, 37 patients with comminuted fracture of distal radius were treated with external fixator or assisted with Kirschner wire and T-shape locking compression plate (T-LCP) fixation. There were 14 males and 23 females, ranging in age from 30 to 79 years, with an average of 59.1 years. According to AO typing, type C1 was in 3 cases, type C2 was in 11 cases and type C3 was in 23 cases. Function of wrist joint and X-ray films were observed according to Gratland-Werley system at different months.</p><p><b>RESULTS</b>All patients were followed up from 8 to 24 months with an average of 12 months. All fractures had healing with an average time of 8 weeks. According to Gratland-Werley system, 16 cases obtained excellent result, 17 good, 4 fair, the rate of excellent and good was 89.0%.</p><p><b>CONCLUSION</b>External fixator can obtained satisfactory clinical effect in treating comminuted fracture of distal radius.</p>
