200 patients admitted to the Chest Surgery Department of Jeonbug National University Hospital from January, 1974 to December, 1981 were analyzed clinically. The ratio of male to female was 7: 1, which showed male predominance. Distribution of patients according to age disclosed that over half [62%] of the patients was social age between 20 and 49 years. The most common cause of chest trauma was traffic accident [39%], and the next were stab wound, fall down [17.5%], and hit [8.5%] in decreasing order. Common lesions due to chest trauma were as follows; rib fracture [51%], hemopneumothorax, hemothorax, and pneumothorax in decreasing number. The most common cause of rib fracture was traffic accident [50%] and the associated organ injuries were long bone fracture, head injury, spine and pelvic bone fracture, spleen rupture, and liver laceration. Hemothorax, pneumothorax, and hemopneumothorax were treated with insertion of thoracic catheter in 90 cases, pure thoracentesis in 11 cases, and emergency thoracotomy in 11 cases. In flail chest, 6 patients were treated by intramedullary insertion of Kirschner`s wire and the results were good. The incidence of complication was 17%, including atelectasis [11 cases], pyothorax, fibrothorax, pneumonia, and acute respiratory failure. Four patients were died [2%], and the causes were acute respiratory failure in 2 cases, spinal cord injury in one case and head injury in one case.

A Korean goral (immature, female) was presented with paraplegia following motor vehicle trauma. The patient was diagnosed with an L5-6 vertebral fracture-luxation based on digital radiographs. Surgical reduction and stabilization of the fracture-luxation were performed via a dorsal approach to the lumbar spine. It was confirmed in surgery that the patient had L5-7 spinous process fractures, L6 bilateral articular process fractures, and an L5-6 luxation. Free fragments were removed and the luxation was reduced. During reduction, caudodorsal dislocation of the L5 caudal vertebral end plate was discovered and the displaced end plate was removed. The L5-6 vertebral luxation was stabilized using pins and bone cement. However, the presence of an intact spinal cord was not confirmed. Two weeks postoperatively the patient became dyspneic and arrested. A necropsy was performed, which revealed that the surgical stabilization was intact. Pulmonary edema was identified and the immediate cause of death was determined to be systemic inflammatory response syndrome.

The authors report two cases of spontaneous regression of disc herniation at the level adjacent to the anterior lumbar interbody fusion (ALIF) level. This phenomenon may be due to the increased tension on the posterior longitudinal ligament (PLL) by appropriate restoration of the disc height and lumbar lordosis, which is a mechanism similar to ligamentotaxis applied to the thoracolumbar burst fracture.

In this paper, three-dimensional finite element analysis have been performed to investigate the biomechanics of vertebroplasty in patient. In order to apply various properties of the spine, the functional relation between the well-known apparent density and HU(Hounsfield unit) from CT image were employed and thus real material property can be assigned to each element of FE model. The FE analysis showed similar results with the experiments. With this approach accurate analysis of the spine and the clinical application can be expected.

목적: 근감소증에 중요한 요소인 척추 주변 근육 감소를 수치화한 총 지방 침윤율(total fat infiltration rate, TFI rate)과 골다공증성 척추 압박 골절(osteoporotic vertebral compression fracture) 및 관련 수치와의 상관 관계를 찾는 것을 목표로 하였다. 대상 및 방법: 2012년 1월부터 2016년 12월까지 요추의 압박 골절 진료를 본 환자들 중 1) 골밀도(bone mineral density, BMD) T score -2.5 g/cm² 미만으로 골다공증을 진단받고, 2) 요추 골절로 경피적 척추성형술(vertebroplasty) 또는 경피적 풍선척추성형술(kyphoplasty)을 받았으며, 3) 요추의 한 분절만 골절된 4) 1년 이상 추시한 환자 98명을 대상으로 후향적 연구를 시행하였다. TFI는 Image J 프로그램으로 자기공명영상을 분석하여 확인하였다. 이를 바탕으로 다열근(multifidus) 및 척추기립근(erector spinae)의 TFI와 골다공증 요소들과의 연관성을 분석하였다. 결과: 다열근및 척추기립근의 평균 TFI는 14.66±10.16이었다. 척추 BMD는 고관절 BMD와 통계적으로 유의한 양의 상관 관계를 보였으나 TFI와 음의 상관 관계를 보였다. 고관절 BMD는 체질량지수(body mass index)와 유의한 양의 상관 관계를 보였다. 또한 비타민 D 수치는 척추 BMD와 고관절 BMD에서 모두 양의 상관 관계를 보였으나, TFI와는 음의 상관 관계를 보였다. 결론: 근육량은 근감소증 환자뿐만 아니라 골다공증 환자의 치료에 있어서도 도움이 되므로 주의깊게 보아야 할 것이다. 또한 비타민 D를 증가시키는 것은 근육 위축의 진행을 늦출 수 있으므로 이로써 골절을 예방하는 효과를 가져올 수 있다.

Background: Water pressure and muscle contraction may influence bone mineral density (BMD) in a positive way. However, divers experience weightlessness, which has a negative effect on BMD. The present study investigated BMD difference in normal controls and woman free-divers with vertebral fracture and with no fracture. Methods: Between January 2010 and December 2014, traditional woman divers (known as Haenyeo in Korean), and non-diving women were investigated. The study population was divided into osteoporotic vertebral fracture and non-fracture groups. The BMD of the lumbar spine and femoral neck was measured. The radiological parameters for global spinal sagittal balance were measured. Results: Thirty free-diving women and thirty-three non-diving women were enrolled in this study. The mean age of the divers was $72.1{\pm}4.7$ years and that of the controls was $72.7{\pm}4.0$ years (P = 0.61). There was no statistical difference in BMD between the divers and controls. In divers, cervical lordosis and pelvic tilt were significantly increased in the fracture subgroup compared to the non-fracture subgroup (P = 0.028 and P = 0.008, respectively). Sagittal vertical axis was statistically significantly correlated with cervical lordosis (Spearman's rho R = 0.41, P = 0.03), and pelvic tilt (Spearman's rho R = 0.46, P = 0.01) in divers. Conclusion: BMD did not differ significantly between divers and controls during their postmenopausal period. When osteoporotic spinal fractures develop, compensation mechanisms, such as increased cervical lordosis and pelvic tilt, was more evident in traditional woman divers. This may be due to the superior back muscle strength and spinal mobility of this group of women.

목적: 경골극 골절에서 관절경을 이용한 골편의 정복 및 고정 후 골절편의 정복 정도와 전방 불안정성에 대한 결과를 알아보고자 하였다. 대상 및 방법: 경골극 골절로 관절경적 치료를 받은 32예를 대상으로 하였으며 평균 추시 기간은 18개월(12개월-48개월)이었다. 수술 후 평가는 Lachman 검사 및 회전 불안정성 검사와 KT-2000 관절측정기를 이용한 건측과의 전방전위차이(SSD)를 측정하였다. 방사선 사진 상 골편의 완전 정복, 전방 거상 및 정복 실패로 나누었고, 골편의 정복 정도에 따른 전방 불안정성 정도를 조사하였다. 결과: 골편의 완전 정복, 전방 거상, 정복 실패는 각각 23예(71%), 8예(25%), 1예(4%)였고 pull-out 방법 28예 중 8예(29%)에서 전방 거상이 있었다. 완전 정복군과 전방 거상군의 SSD는 각각 2.0 mm와 2.8mm로 의미 있는 차이는 없었으나 Lachman 0등급 비율(P=0.021)과 3 mm 미만의 SSD의 비율(P=0.048)은 의미 있게 정복군이 높았다. 결론: 심하게 전위된 골절일수록 골편의 정확한 정복이 술 후 전방 동요를 줄이는데 중요할 것으로 생각되며, 봉합사를 이용한 pull-out 방법에 의한 고정은 수술 후 골편 전방부의 거상을 유발할 수 있으므로 세심한 주의가 필요 할 것으로 생각된다.

In this study, we compared the standardized value of each signal intensity, the apparent diffusion coefficient (ADC) that digitizes the diffusion of water molecules, and the signal to noise ratio (SNR) using b value 0 400, 1400 ($s/mm^2$). From March 2013 to December 2013, patients with suspicion of simple compound fracture and metastatic spine cancer were included in the MR readout. We used a 1.5 Tesla Achieva MRI system and a Syn-Spine Coil. Sequence is a DWI SE-EPI sagittal (diffusion weighted imaging spin echo-echo planar imaging sagittal) image with b-factor ($s/mm^2$) 0, 400, 1400 were used. Data analysis showed ROI (Region of Interest) in diseased area with high SI (signal intensity) in diffusion-weighted image b value 0 ($s/mm^2$) Using the MRIcro program, each SI was calculated with images of b-value 0, 400, and 1400 ($s/mm^2$), ADC map was obtained using Metlab Software with each image of b-value, The ADC is obtained by applying the ROI to the same position. The standardized values ($SI_{400}/SI_0$, $SI_{400}/SI_0$) of simple compression fractures were $0.47{\pm}0.04$ and $0.23{\pm}0.03$ and the standardized values ($SI_{400}/SI_0$, $SI_{400}/SI_0$) of the metastatic spine were $0.57{\pm}0.07$ and $0.32{\pm}0.08$ And the standardized values of the two diseases were statistically significant (p < 0.05). The ADC ($mm^2/s$) for b value 400 ($s/mm^2$) and 1400 ($s/mm^2$) of the simple compression fracture disease site were $1.70{\pm}0.16$ and $0.93{\pm}0.28$ and $1.24{\pm}0.21$ and $0.80{\pm}0.15$ for the metastatic spine. The ADC ($mm^2/s$) for b value 400($s/mm^2$) was statistically significant (p < 0.05) but the ADC ($mm^2/s$) for b value 1400 (p > 0.05). In conclusion, multi - b value recognition of signal changes in diffusion - weighted imaging is very important for the diagnosis of various spinal diseases.
