In this research, the ideal beauty of pelvis which plays an important role in S-line body figure will be studied through hand remedy of the Jokgolgeun Pelvis Reduction Therapy. As age increases, women tend to have a bigger waist circumference, and showed the aging process of pelvis which had a growth in MPB and a decrease in DFH. The process was mainly due to an accumulation of adipose tissue, and especially of the amassment of fat in the belly. This study would approach on the ideal A-type pelvis which has a reduced MPB known as the waist measurements of young women and relatively a wider DFH. This clinical procedure was proceeded twice a week, 8 times in total for 10 weeks on 7 women in their 20s~40s. Jokgolgeun Pelvis Reduction Therapy registered on Copyright Registration(C- 2014-002774) was applied and conducted. MPB, SB and DFH were measured from the PACS image that shows the frontage of the pelvis using the distance measuring function. MPB showed a meaningful decrease of 5.62mm from 327.99mm before the clinical test to 322.37mm (p<.05) after the clinical procedure. SB decreased by 0.11mm from 133.65mm to 133.54mm (p>.05)after the clinical testing. DFH reduced by 1.24mm from 182.55mm to 181.31mm, but the two measurements did not show a volitional difference. Moreover, there was a general decline in the rate of the pelvis size as a matter of change. MPB, the only part that showed a meaningful decrease among the measurements is analyzed as a positive change affected by the Jokgolgeun Pelvis Reduction Therapy, when seeing that the MPB widens during the aging process. The decrease in rate of MPB which is equivalent to the waist measurement of the most ideal A-type pelvis emphasized the silhouette of a female's hips and waist. The proportionate decrease of MPB in contrast to DFH after the clinical testing is analyzed as a recovery towards a younger pelvis. The downsize of middle aged womens' pelvis makes a good ratio of figure proportion in general body-line formation, but above all, it seems to be helpful in balancing health problems such as lumbago or other pelvis related illnesses.

Objective: The aim of this study is to evaluate the accuracy and reliability of Spine-Pelvis Monitor(SPM) that was developed to measure 3-dimensional motion of spine and pelvis using tilt sensor and gyro sensor. Background: The main cause of low back pain is very much associated with the task using the low back and pelvis, but no measurement technique can quantify the both spine and pelvis. Method: For testing the SPM, 125 angles from three anatomical planes were measured three times in order to evaluate the accuracy and reliability. The accuracy of SPM in measuring dynamic motion was evaluated using digital motion analysis system. The motion pattern captured by two measuring methods was compared with each other. In result, the percentage error and Cronbach coefficient alpha were calculated to evaluate the accuracy and reliability. Results: The percentage error was 0.35% in flexion-extension on sagittal plane, 0.43% in lateral bending on coronal plane, and 0.40% in twisting on transverse plane. The Cronbach coefficient alpha was 1.00, 0.99 and 0.99 in sagittal, coronal and transvers plane, respectively. Conclusion: The SPM showed less than 1% error for static measurement, and showed reasonably similar pattern with the digital motion system. Application: The results of this study showed that the SPM can be the measuring method of spine pelvis motion that enhances the kinematic analysis of low back dynamics.

Purpose: The purpose of this study was to analyze the questions in the hip and pelvis section of the Korean Orthopaedic In-Training Examination (KOITE). Materials and Methods: We analyzed all KOITE questions pertaining to hip and pelvis surgery between 2010 and 2014. A thorough analysis of the contents was performed after categorizing as tested topics, imaging modalities used, taxonomic classification, and recommended references. We also analyzed the scores of the hip and pelvis section of the KOITE. Results: Seventy-five of five-hundred questions (weight, 15.0%) were related to the hip and pelvis. Trauma including fracture and dislocation (26/75, 34.7%) was asked more commonly than disease and basics. The description-only questions (65/75, 86.7%) were the most frequently asked. According to taxonomic classification, taxonomy 3 (decision; 39/75, 52.0%) was most frequently asked. Campbell’s Operative Orthopedics (52/75, 69.3%) was the reference that covered most of the questions. Conclusion: This analysis of the hip and pelvis section of KOITE could be used for resident training programs in teaching hospitals.

Purpose: We classified the articles published in the journal Hip & Pelvis and analyzed the relationship between study characteristics and citation rates. Materials and Methods: All articles published in Hip & Pelvis from 2009 to 2019 were included. We classified the articles according to the type, language, listing in PubMed Central (PMC), treatment modality, material, design, anatomical focus, number of authors, and number of cases. We analyzed the citation rate according to this classification, with yearly citation rate reflecting the exposure period until March 2020. Results: The yearly citation rate increased significantly after the language of the journal was changed from Korean to English in June 2014 (mean=0.96 vs. 1.63, P<0.05), and again after the journal was listed in PMC in March 2016 (mean=1.05 vs. 1.92, P<0.05). The yearly citation rates of review articles was highest, followed by those of editorials, original articles, and case reports (in this order). Among original articles, trauma-related articles had higher yearly citation rates than non-trauma-related articles (mean=1.00 vs. 0.68, P=0.034). Among clinical articles, studies focusing on the pelvis had higher yearly citation rates than studies on the hip or femur (mean=1.85 vs. 0.71 vs. 0.91, P=0.003). Conclusion: The yearly citation rate of articles increased significantly after the language of Hip & Pelvis was changed to English and after the journal was listed in PMC. The mean yearly citation rate of articles focusing on the pelvis was significantly higher than that of articles focusing on the hip or femur.

원문 : 태권도 주춤서 지르기 시 골반 종축 선(先)회전 동작의 운동역학적 특성 및 효과

최치선 ( Chi Sun Choi ) 한국스포츠정책과학원(구 한국스포츠개발원) 2013 체육과학연구 Vol.24 No.3

이 연구의 목적은 태권도 주춤서 지르기 시 골반 종축 선회전 동작의 운동역학적 특성을 연구하는데 있다. 이러한 목적을 달성하기 위하여 태권도 품새 전문 선수 11명을 대상으로 동작 속도를 별도 통제하지 않고 최대한 빠르고 강하게 허공의 몸통을 목표로 한 오른손 주춤서 지르기를 5회 실시하였다. 3차원 동작분석 시스템과 지면반력기를 통하여 분석에 필요한 각종 자료들을 획득하였고, 실험대상자를 15개 분절로 모델링 및 지역 좌표계를 설정하여 분석에 필요한 각종 변인들을 산출하였다. 분석 결과, 골반 종축 선회전 동작은 주먹을 지르기 위해 동작을 준비하는 구간에서 골반을 상체보다 먼저 빠른 속도로 목표방향으로 회전시키는 동작으로서, 비선회전 집단은 동작 준비 구간에서 골반과 상체를 거의 동시에 회전시키며 지르기 동작을 시작하는 반면에, 선회전 집단은 골반을 목표 방향으로 비선회전 집단에 비해 먼저 4배 가량 빨리 회전시킨 후 상체의 회전이 뒤따라가는 특성을 나타냈다. 또한 선회전 집단은 비선회전 집단에 비하여 골반의 회전 동작 시간이 짧았고, 허리와 오른쪽 어깨 부위 근육군의 파워가 각각 약 2배와 1.5배 큰 것으로 나타나, 짧은 동작 시간 동안 큰 파워를 내는 숙련된 기술의 특성을 나타냈다. 이 연구의 골반 종축 선회전 동작은 하나하나의 낱기술이 아닌 태권도 전체 기술에 적용될 수 있는 기능으로서, 다른 손동작과 차기 등에 동일하게 적용한다면 빠르고 강한 회전 동작을 만들어 낼 수 있어, 교육 시 태권도 기능 및 경기력 향상에 도움이 될 것이라 기대한다. The purpose of this study was to investigate the biomechanical characteristics and efficiencies of the pelvic axial pre-rotational movement for the Jireugi in the Taekwondo Juchumseogi stance. Eleven elite Taekwondo Poomsae athletes participated in the experiment. Each participant performed 5 right hand Jireugi in Juchumseogi stance as fast and strong as possible while their motion was recorded by a 3D motion analysis system and the ground reaction forces by two force plates. A 15-segment model with 15-local coordinate systems were used. The phase time, axial rotational angle of the pelvis and trunk, relative pelvis-trunk rotational angle, angular velocity, and maximal speed of the fist were measured according to each of the pelvis axial pre-movement conditions. To evaluate the efficiency, the power of the waist and right shoulder were also calculated using the inverse dynamics method. The pelvic axial pre-rotational movement had a pelvis rotation earlier and faster than the trunk during the preparation phase of the Jireugi. For the none pre-rotation group, the pelvis and trunk rotated almost simultaneously, but pre-rotation group rotated the pelvis about 4 times faster than the other group and this led to the trunk’s rotation. The pre-rotation group’s pelvic rotation time was shorter, the power of the waist and the right shoulder were about 2 times and 1.5 times greater respectively, than the none pre-rotation group. Thus, this seems to be a way to characterize skill level. The pelvic axial pre-rotational movement of this study may be applied to the all techniques of Taekwondo such as the hand skills and kicks. It has the effect of shortening of the range of movement, creating a fast and more powerful rotation, thus increasing the magnitude of impact. Therefore if the coaches educate their players to use this movement, then they will be able to produce quicker more powerful techniques.

Background: The sagittal alignment of the spine and pelvis is not only closely related to the overall posture of the body but also to the evaluation and treatment of spine disease. In the last few years, the EOS imaging system, a new low-dose radiation X-ray device, became available for sagittal alignment assessment. However, there has been little research on the reliability of EOS. The purpose of this study was to evaluate the intrarater and interrater reliability of EOS for the sagittal alignment assessment of the spine and pelvis. Methods: Records of 46 patients were selected from the EOS recording system between November 2016 and April 2017. The exclusion criteria were congenital spinal anomaly and deformity, and previous history of spine and pelvis operation. Sagittal parameters of the spine and pelvis were measured by three examiners three times each using both manual and EOS methods. Means comparison t -test, Pearson bivariate correlation analysis, and reliability analysis by intraclass correlation coefficients (ICCs) for intrarater and interrater reliability were performed using R package “irr.” Results: We found excellent intrarater and interrater reliability of EOS measurements. For intrarater reliability, the ICC ranged from 0.898 to 0.982. For interrater reliability, the ICC ranged from 0.794 to 0.837. We used a paired t -test to compare the values measured by manual and EOS methods: there was no statistically significant difference between the two methods. Correlation analysis also showed a statistically significant positive correlation. Conclusions: EOS showed excellent reliability for assessment of the sagittal alignment of the spine and pelvis.

The purposes of this study were to assess dynamic stability toward pelvis-spine column distortion during running and to compare the typical three-dimensional angular kinematics of the trunk motion; cervical, thoracic, lumbar segment spine and the pelvis from the multi-segmental spine model between exercise group and non-exercise group. Subjects were recruited as exercise healthy women on regular basis (group A, n=10) and non-exercise idiopathic scoliosis women (group B, n=10). Data was collected by using a vicon motion capture system (MX-T40, UK). The pelvis, spine segments column and lower limbs analysiaed through the 3D kinematic angular ROM pattern. There were significant differences in the time-space variables, the rotation motion of knee joint in lower limbs and the pelvis variables; obliquity in side bending, inter/outer rotation in twisting during running leg movement. There were significant differences in the spinal column that is lower-lumbar, upper-lumbar, upper-thoracic, mid-upper thoracic, mid-lower thoracic, lower thoracic and cervical spine at inclination, lateral bending and twist rotation between group A and group B (<.05, <.01 and <.001). As a results, group B had more restrictive motion than group A in the spinal column and leg movement behaved like a “shock absorber”. And the number of asymmetry index (AI) showed that group B was much lager unbalance than group A. In conclusion, non-exercise group was known to much more influence the dynamic stability of equilibrium for bilateral balance. These finding suggested that dynamic stability aimed at increasing balance of the trunk ROM must involve methods and strategies intended to reduce left/right asymmetry and the exercise injury.

Case Report : A case of solitary fibrous tumor in the pelvis presenting massive hemorrhage during surgery

( Mi Young Kim ),( Seob Jeon ),( Seung Do Choi ),( Kye Hyun Nam ),( Jae Gun Sunwoo ),( Ji Hye Lee ) 대한산부인과학회 2015 Obstetrics & Gynecology Science Vol.58 No.1

Solitary fibrous tumors (SFTs) are unique soft-tissue tumors of submesothelial origin. These tumors are mainly located in the pleural space but they can be originated within a variety of sites, including the abdomen, the pelvis, the soft tissues and the retroperitoneum. SFTs from all sites are usually benign, and the surgical resection is curative in almost all cases. According to the review of literatures, during the surgical resection, massive hemorrhage could occur due to the hypervascular nature of SFTs. This is a case report on SFT in the pelvis presenting great vessel injury, which resulted in life threatening hemorrhage during the resection of tumor. We wish this paper alerts gynecologists about the risk of massive bleeding during the resection of tumor located at adjacent to great vessels in the pelvis.
