The Ilizarov fixator allows significantly more axial motion at the fracture site than the conventional monofixators. But the transfixing wires have inevitable problems of soft tissue impalement. Therefore the Rancho mounting technique, replacing the transfixing wires with half pins, has become a common place. But the increment of the axial stiffness secondary to replacing transfixing wires with half pins has not been defined clearly yet. The authors measured the axial stiffness of the Ilizarov fixator and two different configurations of the Rancho frame. The group I frame was the Ilizarov fixator composed of four rings and two transfixing wires on each ring. The group II frame was the Rancho frame and it was constructed same as the Ilizarov frame but a transfixing wire was replaced with a half pin from two central rings respectively. The group III frame was another type of Rancho frame which was constructed same as the second group but the remaining transfixing wire was replaced with a half pin from the two central rings respectively. The axial stiffness of the Group I , II and Group III frames were 71.54+/-7.21N/mm, 89.65+/-6.42N/mm, 101.01+/-7.92N/mm respectively. The axial stiffness difference between the Group I frame and the Group II frame was statistically significant(p<0.01). Also the difference between the Group I frame and the Group III frame was statistically significant(p<0.01). This study shows that the replacement of two transfixing wires with two stainless half pins resulted in significant increment of the axial stiffness of the Ilizarov frame.

The microsurgical free vascularized latissimus dorsi myocutaneous flap was successfully applied in the correction of long-term flexion contracture of the left knee due to scalding burn on the paralyzed leg from poliomyelitis. The patient was a 21 year old male, who suffered from 70° of flexion contracture of the left knee due to scalding burn at the age of 7 years. He has had flaccid paralysis of both legs since the age of 2 years. and not been able to ambulate with bilateral crutches and long leg braces. However after posterior capsulotomy, and successful microsurgical free vascularized latissimus dorsi myocutaneous flap, his left knee could be fully extended and fitted into bilateral long leg braces. So he was able to walk with bilateral crutches and discharged from the hospital on the day of 5th week after admission. Therefore microsurgical free vascularized latissimus dorsi myocutaneous flap is recommended for large soft. tissue defects such as those arising from posterior capsulotomy of knee joint used in the correction of flexion contracture from scalding burn scar upon the paralyzed legs from poliomyelitis.

There are many hypotheses of spinal instability after trauma and the concept had been recently changed from 2-column concept by Holdsworth to 3-column concept by Francis Denis & McAfee and also there are controversies about the operative management of the unstable thoracolumbar spine fractures and fracture-dislocations. So we tried to find some relationship between the spinal instability and the effect of the stabilization operation for the fractures and fracture-dislocations in the thoracolumbar spine in this study. Totally 53 cases that stabilization operation had been performed for the unstable fractures and fracture-dislocations of the thoracolumbar spine at Yonsei University Hospital, including Yongdong hospital, from March, 1973 to October, 1984 and followed up over 6 months, were reviewed. 1. Majority of the patients (84.9%) was in an active age group (20–49 years of his age) and more common in males. 2. The first lumbar vertebra was most commonly involved segment (43.3%) and falling from a height was the most common cause of injuries (50.9%). 3. Injuries to the anterior, middle and posterior column of the spine (58.5%) was the most common mechanism of injury according to the classification by Francis Denis and McAfee. 4. The wedged deformity of the involved segment over 50% was usual (71.7%) and mean wedged deformity was 57% of the height of the vertebral body and most commonly associated fractures besides the body itself was laminae fractures (46.5%). 5. Seventy eight percent of the angular deformity was corrected after Luque rod instrumentation and 76%, after Harrington rod instrumentation, 68%, after posterior wiring, 58%, after anterior decompression and anterior interbody fusion. 6. Forty twa point seven percent of the displacement in anteroposterior plain X-ray film and 58.8% in the lateral film were corrected by Luque rod instrumentation and 39.5% in anteroposterior film and 44.3% in the lateral film were corrected by Harrington rod instrumentation. 7. No significant differences in the recovery of the neurologic signs were found according to the method of surgical treatments. 8. So Luque rod or Harrington rod instrumentation is now recommended for obtaining the spinal stability as a method of surgical treatment in the unstable thoracolumbar spine fractures and fracture-dislocations.

PURPOSE: The purpose of this study was to explore the relationships of critical thinking disposition (CT), nursing work environment (NWE), and clinical decision making ability among nurses. METHODS: A cross-sectional, descriptive study design was conducted on 192 nurses who had worked for more than six months in five general hospitals. A self-reported questionnaire was used to collect data, which included demographics, CT, NWE, and clinical decision making ability. RESULTS: The mean score of CT was 3.5. The highest score was on the objectivity of CT and the lowest on systematicity. The mean score of NWE was 2.3. The highest score was on the collegial nurse-physician relations of NWE and the lowest on the staffing and resource adequacy. The mean score of clinical decision making ability was 3.3. In hierarchical multiple regression, affecting factors on clinical decision making ability were CT and NWE. CONCLUSION: The findings showed that clinical decision making ability is associated with CT and NWE. To improve clinical decision making ability, it is important to improve CT. In addition, it should be considered to improve NWE where the nurses can make a decision with their job through critical thinking.
