To evaluate the bone mineral density (BMD) and biochemical markers. We evaluated the BMD of femoral neck and lumbar spines of 998(male 568, female 430) persons who took a regular health screening in Woosuk University Hospital from September 2007 to March 2008 by dual energy bone mineral densitometry. Results of BMD are different in terms of biochemical markers. Especially aged people showed osteoporotic change progressively. Degree of osteoporosis increases with age. A steep decrease of BMD can be found in postmenopausal women who have low level of female hormone. More persistent effort is needed to find out the factors that can reduce BMD values for prevention of problems by osteoporosis. In essence, research on factors related to other biochemical markers must be studied continuously.

Objectives : To introduce the Jeongham Therapy which means a mandibul-rectifying treatment. And to show meaningful changes of thoracic kypkosis and lumbar lordosis by the Jeongham Therapy. Methods : We reviewed 8 patients having abnormal thoracic kyphosis and lumbar lordosis who were treated at the JeongHam Korean Medical Clinic. We measured thoracic kyphosis and lumbar lordosis by 3D Body Analyzer 'IBS 2000'. Results : Between before and after the Jeongham Therapy, statically significant differences were found in the thoracic kyphosis and lumbar lordosis. And in these values of measurements, the thoracic kyphosis and lumbar lordosis diminish after the Jeongham Therapy. Conclusion : These results suggest that the Jeongham Therapy is a meaningful therapy to diminish the thoracic kyphosis and lumbar lordosis.

Chronic irritation to arterial wall by foreign material may give rise to delayed vascular injury. A 50 years old male patient with kyphoscoliosis had undergone fixation of orthopedic Cotrel-Dubousset(CD) rods and screws. Fourteen months after that surgery, a false aneurysm of the descending thoracic aorta associated with pulsating hematoma in the muscular chest wall developed. The false aneurysm was managed by resecting the diseased aortic segment and replacing the vascular graft.

인류가 언제부터 결핵 때문에 고생했는지 확실히 알수는 없으나 우리가 현재 알고 있는 가장 오래된 증거는 독일의 하이델베르크에서 기원전 약1만년 석기시대의 사람 뼈에서 척추결핵이 증명된 예일 것이다. 그리고 그 후대에는 이집트의 미이라에서도 척추결핵의 흔적이 발견되었다. 이와 같이 오랫동안 우리 인류와 더불어함께 있어 왔기 때문에 결핵을 고치려고 하는 노력은 동서양을 막론하고 꾸준히 계속되어 왔다. 그러나 실제로 고칠수 있게 된지는 얼마되지 않는다. 치료행위는 그 목적에 따라 여러 가지로 분류할 수 있겠으나 크게 다음의 둘로 나눌 수도 있을 것이다. 그 첫째는 환자의 고통을 덜어주려고 하는 보살핌(care)이 있을 것이고, 둘째는 질병 자체를 치료에 의해서 고쳐주는 일(cure)이 되겠는데 둘다 필요하지만 궁극적인 목적은 질병을 고쳐주어서 건강상태로 회복시키는 일이어야 할 것이다. 이런면으로 볼 때 1950년까지의 결핵치료의 역사는 고치는 것을 목적으로 하면서도 고칠수 있는 방법이 없었기 때문에 일종의 보살펴주는 일에 그쳤다고 할 수 있을 것이다. 이제 결핵치료의 확실한 방법이 확립되고 증명된 마당에 와서도 과거 치료할 수 없었던 시대에 이용되거나 유행하였던 효과 없는 방법을 쓰는 환자가 있는 것은 매우 개탄스럽고 걱정이 되는 일이다.

Objectives : This study was performed to evaluate the clinical results of the spodylolisthesis patients treated with oriental medical methods. Methods : We diagnosed spondylolisthesis by L-spine simple x-ray. 28 patients with spondylolisthesis were hospitalized at WonKwang University KwangJu Oriental Medical Hospital from April 1997 to January 2000 and treated by acupuncture, moxibustion, bed rest, herb-medicine and physical therapy. Results : 1. Distribution showed female predominence(82.1%) in general. 2. In the duration of symptoms, the largest group was the group of "acutest" (32.1%). 3. In the distribution of causes, the largest group was "overwork" (35.7%). 4. Isthmic type is the most common(75%) in etiology. 5. Isthmic type involved the 5th lumbar vertebra in 57.1% and degenerative type involved the 4th lumbar vertebra in 57.1%. 6. Most of cases were grade I(96.4%) in degree of slipping. 7. The common symptoms were radiating pain(92.9%) and low back pain(78.6%). 8. Therapeutic efforts above "good" by Kim's criteria was 20 cases(71.4%) Conclusions : The result of treatment by oriental medical methods is satisfactory for the treatment of spondylolisthsis.

This study aimed to investigate changes in benthic macroinvertebrate communities caused by erosion control dams using data obtained from three erosion control dams in Wonju, Gangwon Province, before and after the rainy season. Surveys were conducted four times from March to September 2019, and survey points were continuously selected during the installation of closed-type and open-type dams. A total of eight points from the upstream and downstream regions of each dam type were selected. The flow velocity of both the closed and open types increased, but the closed type exhibited a relatively higher flow velocity than the open type. Benthic macroinvertebrate species and individuals mostly decreased after the rainy season. A relatively large number of species and individuals were found upstream of the closed-type dam. An analysis of the ephemeroptera-plecoptera-trichoptera groups showed relatively reduced ephemeroptera in the closed-type dam and reduced trichoptera in the open-type dam. The periods before and after the rainy season could be divided based on the results of a similarity analysis. The open type showed relatively minimal changes before and after the rainy season.

If a solitary spinal lesion is found in an older patient, bone metastasis can be primarily considered as the diagnosis. Bone metastasis can occur anywhere, but it mostly occurs in the vertebral body and may sometimes show typical imaging findings, presenting as a single lesion. Therefore, differentiating it from other lesions that mimic bone metastases can be challenging, potentially leading to delayed diagnosis and initiation of primary cancer treatment. This review provides an overview of imaging findings and clinical guidelines for bone metastases and discusses its differences from other diseases that can occur as solitary spinal lesions in older patients.

Purpose To assess the prevalence of incidentally detected lumbar spondylolysis in children. Materials and Methods We retrospectively reviewed the data of 809 patients under the age of 11 years (mean age, 7.0 ± 2.7 years; boys:girls = 479:330) who underwent abdominal and pelvic CT between March 2014 and December 2018. We recorded the presence, level, and laterality (unilateral or bilateral) of spondylolysis. Patients were divided into two groups based on the presence of spondylolysis: the spondylolysis (SP) and non-SP groups. Results In total, 21 cases of spondylolysis were detected in 20 patients (20/809, 2.5%). The mean age of the SP group was higher than that of the non-SP group (7.8 ± 1.8 vs. 6.9 ± 2.7 years, p > 0.05). The prevalence of spondylolysis in boys was higher than that in girls (15/479 [3.1%] vs. 5/330 [1.5%], p > 0.05). The prevalence of spondylolysis in school-age children (6-10 year olds) was higher than that in preschool-age children (0-5 year olds) (17/538 [3.2%] vs. 3/271 [1.1%], p > 0.05). L5 was the most common level of spondylolysis (76.2%); one 8-year-old boy had two-level spondylolysis. One case of isthmic spondylolisthesis was detected in a 10-year-old boy (1/809, 0.1%). There were 11 unilateral spondylolysis cases (11/21, 52.4%). Conclusion In our study, the prevalence of spondylolysis in children under the age of 11 was 2.5%. The prevalence was higher in boys than in girls and in school-age than in preschool-age children, despite the lack of any statistically significant differences.

Metastatic bone tumor is the most common bone tumor and 32.5% of all primary malignant tumors are eventually metastasize to bone. Metastatic bone tumor has been more frequently encountered disease in the orthopedic fields due to the greater longevity of life of the patients with primary visceral cancers by major advances in early detection, diagnosis, and surgical/radiotherapeutic/chemotherapeutic treatment of primary and metastatic lesions. Therefore, the epidemiologic data about the incidences and the patterns of bone metastasis is important. We reviewed 417 patients who were diagnosed and treated for metastatic bone tumor at Kosin University Medical Center from 1985 to 1993 to analyse the primary lesion, age and sex distributions, location of bone metastasis, patterns of metastasis according to the primary. The results were as follows : 1. The common origin of bone metastasis were lung(29.5%), stomach(15.3%), breast(11.3%), unknown(7.7%), cervix(5.3%), liver(4.8%) in order of frequency. 2. There were 251 men and 166 women and their mean age was 54.8 years and the peak age incidence was in 6th decades. Most cases(85.3%) were occured beyond 5th decades. 3. The preferred sites of metastatic deposits were spine(64.0%), pelvis(40.5%), rib(38.8%), femur(36.7%), skull(21.1%), humerus(13.9%), scapula(13.0%) in order of frequency. In the spine, thoracic(42.1%), lumbar(39.1%), cervical(13.2%), sacral(5.6%) vertebrae were involved in order of frequency. 4. Multiple bone metastases were more common(73.1%) than single metastasis(26.9%). 5. In the lung cancer, the peak age incidence was 6th decades, and the preferred sites of bone metastasis were spine, pelvis, femur. 6. In the stomach cancer, the peak age incidence was 6th decades, and the preferred sites of bone metastasis were spine, femur, pelvis. 7. In the breast cancer, the peak age incidence was 5th decades, and the preferred sites of bone metastasis were spine, rib, pelvis. 8. In the bone metastasis with unknown primary site, the peak age incidence was 7th decades, the preferred sites of bone metastasis were spine, femur, pelvis, and the common histologic types were adenocarcinoma and squamous cell carcinoma.

Purpose: The need for revision fusion surgery after spinal fusion has increased. A revision rod that connects to the previous rod was newly developed for revision surgery. The purpose of this study was to analyze the clinical and radiological results after spinal fusion revision surgery using revision rods. Materials and Methods: Twenty-one patients who underwent revision fusion surgery after spinal fusion in two university hospitals with minimum 1 year follow-up were reviewed. This study assessed 16 cases of adjacent-segment disease, four cases of thoracolumbar fracture, and one case of ossification of ligament flavum. The Oswestry Disability Index (ODI) and numerical rating scale (NRS) were evaluated as clinical outcomes, and the union rate, lordosis or kyphosis of the revision level, lumbar lordosis, T5-12 kyphosis, and proximal junctional kyphosis angle were evaluated as the radiological outcomes. Results: The average ODI was 54.6±12.5 before surgery and improved to 29.8±16.5 at the final follow-up. The NRS for back pain and leg pain was 5.0±1.7 and 6.4±2.0 before surgery, which changed to 2.9±1.6 and 2.9±2.2 at the final follow-up. Lumbar lordosis was 18.1°±11.9° before surgery and 21.1°±10.3° at the final follow-up. Proximal junctional kyphosis was 10.8°±10.1° before surgery, and 9.2°±10.5° at the final follow-up. These angles were not changed significantly after surgery. Bony union was successful in all cases except for one case who underwent posterolateral fusion. Conclusion: Revision surgery using a newly developed revision rod on the thoracolumbar spine achieved good clinical outcomes with successful bony union. No problems with the newly developed revision rod were encountered.
