Purpose: This study was performed to analyze the characteristics of calcaneocuboid joint involvement in intraarticular calcaneal fractures. Materials and Methods: Total number of 92 patients (111 cases) who underwent operation for intraarticular calcaneal fractures between Jan. 2000 and Oct. 2005 were included in this study. The preoperative computed tomographs of the subjects were retrospectively reviewed to analyze calcaneocuboid joint involvement. Results: It was revealed that 63 cases (56.8%) involved calcaneocuboid joint; 29cases (46.0%) showed type 1 (undisplaced or minimally displaced type, articular gap ${\le}1\;mm$), 16 cases (25.4%) exhibited type 2 (moderately displaced type, articular gap ${\ge}2\;mm$), 7 cases (11.1%) were included in type 3 (comminuted type) and 11 cases (17.5%) belonged to type 4 (fracture and dislocation). 48 out of 63 cases belonged to Sanders classification II and III that involved calcaneocuboid joint and included 25 cases (52.1%) of type 1 and 14 cases (29.2%) of type 2. Among 15 out of 63 cases included in Sanders classification IV, 4 (26.7%) showed type 1 and 6 (40.0%) belonged to type 4. According to our results, Sanders classification allowed to predict pattern of the involvement of calcaneocuboid joint (P<0.05). However, there was no statistically significant relationship between degree of posterior facet joint injuries and calcaneocuboid joint involvement (P>0.05). Conclusion: Calcaneocuboid joint involvement in intraarticular calcaneal fractures was common and more than half showed severe injuries. We concluded that further studies on the involvement of calcaneocuboid joint should be performed prior to surgical treatment of intraarticular calcaneal fractures.

Purpose: To evaluate the clinical features and radiographical landmarks of patients who has a thoracolumbar fracture combined with posterior ligament complex injury retrospectively. Materials and Methods: The preoperative plain radiographys, axial CT, MRI and medical records of 27 patients were reviewed who were confirmed the posterior ligament complex injury in operation from January, 2002. to December, 2004. Results: The patients were from 15 years to 75 years of age (mean 39.1 years), 20 males and 7 females. The mechanisms of injury were 17 falls from a height, 7 traffic accidents and 3 direct blow injuries. There were 17 cases (63%) in thoracolumbar transitional zone, such as 11 cases in T11-T12, 6 cases T12-L1. There were 9 cases of compression fracture and 18 cases of burst fracture according to the shape of fractured vertebra. In the plain radiograph, the degree of kyphotic angle was between 6~49° (mean 22°), anterior vertebral height loss was 7~70% (mean 39%), and posterior vertebral height loss was 0~8% (mean 3%). 21 cases (78%) were the anterior vertebral height loss below 50%, 23 cases (85%) were the degree of kyphotic angle below 30°. Neurological deficits were not registered. 23 cases (85%) were positive in MRI and 24 cases (89%) were positive in direct focal tenderness in the view of posterior ligament complex injury. Conclusions: The posterior ligament complex injury is common finding of the thoracolumbar fracture. The high resolution MRI findings and direct focal tenderness are very importance in identifying the posterior ligament complex injury that is important prognostic factor particularly in mild anterior vertebral height loss and mild kyphotic angle in the plain radiograph.

Study Design: Retrospective study. Objectives: To compare the clinical results of kyphoplasty between osteoporotic patients with compression fractures and rib hot uptake on bone scan and patients without rib hot uptake. Summary of Literature Review: The incidence of osteoporotic rib fractures is 0.3% in postmenopausal women. Materials and Methods: Between July 2005 and July 2006, 72 kyphoplasties for osteoporotic vertebral compression fractures were performed, and all patients had a bone scan study. On bone scan study, 41 patients (57.7%) had hot uptake in their ribs. Results were assessed by visual analog scale (VAS). Results: The incidence of hot uptake was 67.8% in thoracic fractures, 40.0% in lumbar fractures, and 72.7% in thoracolumbar fractures. Hot uptake was significantly more common with thoracic and thoracolumbar fractures than with lumbar fractures (p<0.05). The incidence of hot uptake was 49.1% in one- and two-level fractures and 84.6% in over three-level fractures. This finding demonstrated significant difference between the two groups (p<0.05). The mean VAS scores for all cases were 8.2/3.4/3.2 at preoperative/immediate postoperative/after 3 months, respectively. In thoracic fractures, they were 8.2/3.9/3.1; lumbar fractures 8.0/3.2/3.1; and thoracolumbar fractures 8.3/3.7/3.0, respectively. The immediate postoperative VAS score in lumbar fractures was better than in thoracic fractures (p<0.05). The VAS scores in thoracic fractures with hot uptake were 8.3/4.1/3, and those without hot uptake were 7.8/2.8/3.0. The immediate VAS score in thoracic fractures without hot uptake was better than in those with hot uptake (p<0.05). Conclusions: Thoracic and multiple osteoporotic compression fractures are often accompanied by rib fractures. Bone scan is a useful tool to detect rib fractures and predict the prognosis of kyphoplasty.

기업의 생산성향상과 이익률에 영향을 줄 수 있는 지식이 경제 전반에 확산되어 나가는 과정은 한 나라의 경제발전속도에 영향을 미치는 중요한 요인이다. 기업 측면에서는 도입하려는 기술이 도입 후에 그 기업의 이익을 높여 줄 수 있다면 도입하지 않을 이유가 없다. 하지만 미래 수요의 불확실성이나 기술발전 방향의 불확실성 등으로 해서 기업으로서는 도입 후의 이익을 정확히 사전적으로 측정하기는 어렵다. 본 논문에서는 학계에서 일반적으로 사용되고 있는 두 가지 지식확산 모델을 설명하고자 한다. 그 하나는 하나의 새로운 기술이나 상품이 시간이 흐름에 따라 어떻게 전체 사용 가능자(populion)에게 확산되는 지를 보여주는 1) Epidemic DiffusionModel (흔히 S자형 - Sigmoid - 모델이라고도 한다.)과 어떤 도입자가 어느 시점에서 대상이된 새로운 기술을 도입할 것인지 아닌지를 결정하는 모델로서 2) Probit Diffusion Model (프로빗 모델)을 중심으로 한다. 그리고 이러한 지식확산과정과 속도에 영향을 줄 수 있는 기업 내부적 요인으로서 도입하고자 하는 기업의 누적된 경험이 중요하다는 것과 기업 외부적 요인으로서 네트웍 효과와 같은 요인들을 설명하였다.

Study Design: This is a retrospective study. Objectives: We wanted to compare and evaluate the results of using one cage and two cages with local bone grafting for each segment when performing posterior lumbar interbody fusion (PLIF). Summary of Literature Review: Some authors have reported that unilateral one-caged PLIF with local bone grafting and posterior instrumentation was no difference from bilateral two-caged PLIF regard to the fusion rates and the radiologic or clinical results. Materials and Methods: From March 2005 to February 2006, PLIF was performed on 36 patients who had lumbar degenerative disease. They were categorized as the cases for which one cage was used for a segment and the cases for which 2 cages were used for a segment. The clinical and radiological results in each group were compared. Results: There was complete union in 11 segments with using one cage (55%), complete union in 12 segments using two cages (77%) and incomplete unions in 9 segments with using one cage (45%) and incomplete union in 4 segments with using 2 cages (25%), and there wasn't any case of nonunion (p>0.05). The postoperative changes of the intervertebral disc space were a 2.0 mm increase with using one cage and a 2.2 mm increase with using two cages, yet these values decreased by 0.4 mm and 0.3 mm, respectively, on the last follow-up. The mean operation time was 89 minutes for one segment with one cage and 105 minutes for one segment with two cages. The blood loss was a mean of 602 ml with one cage and 802 ml with two cages (p>0.05). There was no significant difference between the one cage group and the two cages group for the Kirkadly-Willis criteria. Conclusion: Posterior decompression and PLIF with one PEEK cage for treating degenerative lumbar disease was more effective for the operation time and the amount of blood loss than that with two cages, but the fusion rate, the alteration of the intervertebral disc space, the improvement of pain and the clinical results were no different. However, these results are from short term follow up, so continuous follow up will be necessary in the future for assessing the long term prognosis. 연구계획: 후향적 연구 연구목적: 후방 추체간 유합술에서 각 분절당 한 개의 PEEK cage를 사용한 경우와 두 개의 PEEK cage를 사용한 경우 의 방사선학적 결과 및 임상적 결과를 비교 분석하고자 하였다. 대상 및 방법: 2005년 3월부터 2006년 2월까지 퇴행성 요추 질환으로 진단받고 후방 감압술과 PEEK cage를 이용한 후방 추체 간 유합술을 시행 받은 후, 1년 이상 추시가 가능했던 36명을 후향적 방법으로 비교 분석 하였다. 1분절 수 술시 한 개의 cage를 사용한 경우 20명, 두 개의 cage를 사용한 경우 16명이었다. 최종 추시 시 단순 방사선 사진에서 유합의 정도, 수술 전후 및 최종 추시 시의 추간판 간격 변화, 수술 시간, 출혈량 및 수술 전후 요통과 방사통의 호전 을 visual analogue scale(VAS)로 평가하였고, 임상적 결과는 Kirkaldy-Willis방법으로 평가하였다. 결과: 단순 방사선 사진 상 완전 유합은 한 개의 cage를 사용한 경우 11분절(55%), 두 개의 cage는 12분절(77%), 불완 전 유합은 한 개의 cage 9분절(45%), 두 개의 cage 4분절(25%)이었고 불유합을 보이는 경우는 없었다. 두 군 간의 유 의한 차이는 없었다(p>0.05). 추간판 간격의 변화는 시술 직후 한 개의 cage 평균 2.0 mm 증가, 두 개의 cage 2.2 mm 증 가하였고, 최종 추시 시 한 개의 cage 평균 0.4 mm, 두 개의 cage 0.3 mm 침강하여 두 군 간의 유의한 차이는 없었다 (p>0.05). 수술 시간은 한 개의 cage 평균 89분, 두 개의cage 평균 105분으로 두 군 간의 유의한 차이가 있었다(p<0.05). 수술 중 출혈량은 한 개의 cage 평균 602 ml, 두 개의 cage 평균 802 ml로 두 군 간의 유의한 차이가 있었다(p<0.05). 임 상적 평가 결과에 의하면 한 개의 cage의 경우 85.0%에서, 두 개의 cage의 경우 81.3%에서 양호 이상의 결과를 보여 두 군 간의 유의한 차이는 없었다(p>0.05). 결론: 퇴행성 요추 질환으로 PEEK cage를 이용한 후방 감압 및 후방 추체간 유합술을 시행시, 한 개의 cage를 이용한 경우가 두 개의 cage를 이용한 경우 보다 수술 시간 및 출혈량은 줄일 수 있으면서, 추체간 유합율 및 추간판 간격 변 화에서는 차이가 없었고, 통증 감소의 정도와 임상적 결과에서도 차이가 없다는 결론을 얻었다. 그러나 본 연구는 단 기 추시 결과로서 향후 장기적 예후는 지속적인 추시 관찰이 요구된다.

전득수,신원주,안병근,백제원,박민호 대한척추외과학회 2015 Asian Spine Journal Vol.9 No.2

Study Design: Retrospective study. Purpose: To investigate the relation between the progression of kyphotic deformity and magnetic resonance imaging (MRI) findings in conservatively treated stable thoracolumbar fractures. Overview of Literature: When treated conservatively, excessive progression of kyphotic deformity and vertebral compression can emerge during follow-up. We sought to identify predictors of vertebral body deformation using MR images. Methods: The presence in MR images of anterior longitudinal ligament (AL) or posterior longitudinal ligament (PL) injury, superior or inferior endplate disruption, superior or inferior disc injury in fractured vertebral bodies, the existence of low signal intensity on T2 weighted images, and bone edema of intravertebral bodies were assessed. Results: The presence of superior endplate disruption and a higher level of bone edema were found to cause the progressions of kyphotic angle (KA), wedge angle (WA), and anterior vertebral compression (AVC) rate. When AL or superior disc injury was observed, only KA increased meaningfully. When low signal intensity was present on T2 weighted images WA and AVC increased significantly, but PL injury, inferior endplate disruption, and inferior disc injury showed no notable correlation with kyphotic deformity progression. The risk factors found to be associated with an increase of KA to >5° were AL injury, superior endplate disruption, superior disc injury, and a bone edema level of over 1/3, and their associated risks versus no injury cases were 14.1, 3.7, 6.8, and 10.4-fold, respectively. Conclusions: AL injury, superior endplate and disc injury, or a high level of bone edema, were critical factors that determine kyphotic deformity progression.

In a trial involving 72 pigs, the effects of market weight and gender on the carcass and pork quality characteristics were investigated. A total of 72 pigs were divided into 3 groups(95-104, 105-110 or 111-120kg), market weight was assigned to 2 gender group (gilt or boar). The carcass characteristics (carcass weight, backfat thickness or grades) were determined on those carcass, longissimus muscle was removed from each left side at 5th to 13th rib and meat qualities were evaluated. The carcass weight and backfat thickness of pigs slaughtered at 111-120kg were increases than the other weights. The carcass grade of pigs slaughtered at 105-110kg had higher then at pigs slaughtered 94-104kg. Compared with boars, gilts carcass had higher in carcass weight and backfat fat. The pH$\_$u/, drip loss and cooking loss tended to similar for market weight and gender, meat of boars had higher shear force values than gilts (p<0.05). The meat color tended to similar for market weight and gender. The total myoglobin content of gilts slaughtered at 95-104kg and boars slaughtered at 111-120kg had higher than the other weight and gender. The meat of gilts had higher springiness and brittleness than boars (p<0.05). These results imply that the carcass characteristics (carcass weight and backfat thickness) could be affected by market weight and gender, meat of gilts was improved the shear force values and texture properties when compared to boars.
