대퇴직근은 슬관절을 신전하고 고관절을 굴곡하는 근육이며, 빠르고 강한 수축을 하는 제 2형 근섬유로 이루어져 있으며 두개의 관절을 거치므로, 운동 경기 중에 근위부 대퇴직근의 손상이 흔히 발생할 수 있다. 소아에서 발생하는 전하장골극에서의 대퇴직근 견열 골절이 가끔 보고가 되고 있고, 성인에서의 대퇴직근 근위부의 근-건 결합부 완전 파열은 반복적인 운동에 의해 드물게 발생하며, 외상과 관련이 없는 경우 대퇴부에서의 연부조직 종양으로 오인될 수 있다. 그러나, 릴레이 경주 중에 대퇴직근 근위부의 기시부가 급성으로 완전 파열된 예는 아직까지 보고된 바가 없다. 이에 저자들은 릴레이 경주 중에 발생한 중년 남성의 대퇴직근 기시부의 급성 완전 파열에 대하여 자기공명영상을 통하여 확인한 후 수술적 치료를 시행하였으며, 이를 문헌 고찰과 함께 보고하고자 한다.

Objective: This study aimed to investigate the usefulness of bone single-positron emission tomography/computed tomography (SPECT/CT) of the hip in predicting the later occurrence of avascular necrosis (AVN) after slipped capital femoral epiphysis (SCFE) or femoral neck fracture in pediatric patients. The quantitative parameters of SPECT/CT useful in predicting AVN were identified. Materials and Methods: Twenty-one (male:female, 10:11) consecutive patients aged < 18 years (mean age ± standard deviation [SD], 11.0 ± 2.7 years) who underwent surgery for SCFE or femoral neck fracture and postoperative bone SPECT/CT were included. The maximum standardized uptake value (SUV), mean SUV, and minimum SUV of the femoral head were measured. The ratios of the maximum SUV, mean SUV, and minimum SUV of the affected femoral head to the contralateral side were determined. Patients were followed up for > 1 year after the surgery. The SPECT/CT parameters were compared between patients who developed AVN and those who did not. The accuracy of SPECT/CT parameters for predicting AVN was assessed. Results: Six patients developed AVN. There was a significant difference in the ratio of the mean SUV among patients who developed AVN (mean ± SD, 0.8 ± 0.3) and those who did not (1.1 ± 0.2, p = 0.018). However, there were no significant differences in the ratios of the maximum and minimum SUV between the groups (all p = 0.205). For the maximum, mean, and minimum SUVs, no significant differences were observed between the groups (p = 0.519, 0.733, and 0.470, respectively). The cutoff mean SUV ratio of 0.87 yielded a 66.7% sensitivity and 93.2% specificity for predicting AVN. Conclusion: Quantitative bone SPECT/CT is useful for evaluating femoral head viability in pediatric patients with SCFE or femoral neck fractures. Clinicians should consider the high possibility of later AVN development in patients with a decreased mean SUV ratio.

The role of cervical proprioceptors in the control of body posture was studied in bilaterally labyrinth-ectomized, decerebrate cats. The animals were suspended on hip pins with the neck extended horizontally. With this placement the EMG activities of extensor and flexor muscles of the upper extremities were observed by means of sinusoidal head rotator. The rotator can induce two kinds of neck movement: The one is 'pitch' which describes a rotatory neck motion to transverse axis of the body and mainly occurs at skull-C1 (atlantooccipital) joint and the other is 'roll', side-to-side relation of the neck to longitudinal axis, whose center is C1-C2 (atlanto-axial) joint. The following results were obtained. 1) Responses of EMG activity were closely dependent on the rotatory range of the neck. And the EMG activity was not changed during sustained neck torsion, eliciting a typical tonic neck reflex. 2) On pitching movement, the head-up rotation produced the excitation of bilateral triceps muscles, whereas the head-down rotation produced the inhibition. And the response of bilateral biceps muscles was the opposite to that of triceps. 3) On rolling movement, the side-up rotation of the head produced the excitation of ipsilateral triceps muscles and the inhibition of contralateral ones. And the response of biceps muscles was the opposite to that of triceps. 4) The minimum requirement of motion to evoke EMG activities in the upper extremities was $3.2^{\circ}{\sim}12.5^{\circ}$. These results have shown that the cervical proprioceptors produce tonic discharge on the upper brachial muscles, regulate the EMG activities of those muscles, and are very sensitive to neck rotation. And it can be stated that the cervical proprioceptors may play an important role in the control of body posture and movement.

활액막 연골종은 관절의 활액막에서 결체조직의 화생에 의해 연골 조직이 형성되는 질환이며 드물게 건초, 활액낭에 발생하는 경우도 있다. 정확한 발생 기전은 아직 밝혀지지 않았으나 외상, 감염 등이 원인으로 제시되고 있으며 관절 연골을 구성하던 연골의 일부가 떨어져 나와 활액막내로 흡수되어 연골성 화생을 일으킨다는 가설이 유력하다. 주로 슬관절에 발생하며 그 외 견관절, 주관절, 고관절 등에서 발생하는 것으로 알려져 있다. 65세 남자가 약 6개월 간의 우측 주관절 동통, 주관절 구축 및 우측 제1수지와 완관절의 신전 장애 및 감각 저하를 주소로 내원 하였다. 단순 방사선 검사상 주관절의 관절 간격이 좁아져 있었고 관절면의 가장 자리에 골극이 형성되어 있었으며 연골하골은 경화소견이 관찰되었다. 자기 공명 영상 검사상 요골두 직하방 전외측에 약 $16{\times}12$ mm 크기의 원형의 종양이 관찰되었으며, T1 강조 영상에서 균질의 저신호 강도, T2 강조 영상에서 고신호 강도와 저신호 강도가 혼재되어 있었다. 종양 절제술을 시행하였으며 수술소견상 종양에 의해 요골신경이 압박되어있는 소견이 관찰되었다. 절제한 종양은 조직소견상 활액막 연골종으로 진단되었다.

Purpose: Bone contusion is usually treated with conservative therapy for 3 months. Bone contusion around knee and hip joints has been extensively reported on, but there are scant reports on this condition in foot and ankle joints. This study evaluated the nature, characteristics and location of bone contusion around foot and ankle joints to enlighten clinicians on how to better treat this disease entity. Materials and Methods: We classified bone contusion of the 76 patients into three types (102 sites; 47 ankle sprains, 18 traffic accidents, 11 falls) according to the Costa-Paz system with employing magnetic resonance imaging (MRI), and the study then analyzed the common sites and areas of occurrence according to the mechanism of injury and duration of pain after first conducting conservative therapy. Results: Of the 76 patients (102 sites) on the MRI, 43 case (42.2%) for talus, 19 cases for distal tibia, and 12 cases for calcaneus were involved. The classification, according to the Costa-Paz system, was Type I, 51 cases; Type II, 32 cases; and Type III, 19 cases. The duration of pain after conservative treatment was 12.15±2.17 weeks for Type I, 14.5±2.15 weeks for Type II, and 21.0±3.8 weeks for Type III. Conclusion: The most common location of post-traumatic bone contusion around both the foot and ankle is the talus, distal tibia, and calcaneus. The most common type of injury noted on MRI is a diffuse signal with change of the medullary component (Type I), In cases of bone contusion extending to a subjacent articular surface or disruption or depression of the normal contour of the cortical surface (Types II, III), the patients' pain appears to last longer. Thus, it is necessary to consider a longer period of conservative treatment in cases of Types II and III bone contusion because the patients' pain may last longer than 3 months.

Sacral insufficiency fractures (SIF) are a common, but often underdiagnosed source of lower back pain without apparent trauma. This report presents the clinical outcome of a 75-year-old female with SIF, and an underlying medical history of osteoporosis and rheumatoid arthritis. She was treated non-operatively, in-hospital, with Korean medicine. Patient progress was assessed using the numerical rating scale and self-reported symptoms. Post-treatment, the numerical rating scale score for pain in her hip decreased from 7 to 2. At admission, the patient was unable to sit, and could only walk 3 m with assistance. At discharge, she could sit for longer than 1 hour and walk further than 200 m unassisted. On the follow-up visit, the patient was asymptomatic, and x-ray scans showed ossification of the sacral and pubic fractures. These results suggest that, Korean medicine can effectively reduce pain and aid rehabilitation in patients with SIF, without the need for surgery.

The purpose of this study was to investigate the effects of appearance instrumentality on body satisfaction and appearance management behaviors by adolescent' sex. The subjects were 750 adolescents in Daejeon and Chungnam province. The research method was a survey and the measuring instruments consisted of appearance instrumentality, body satisfaction, appearance management behaviors, and subjects' demographics attributions. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, cluster analysis, ${\chi}^2$ test, and t-test, using SPSS statistical program. The results were as follows. First, 3 dimensions(the utility of interpersonal relationship, social achievement and sexual partnership) were emerged on appearance instrumentality, and adolescents were divided into 2 groups(unreceptive and receptive group) by appearance instrumentality. Second, appearance instrumentality had significant effects on female adolescents' body satisfaction; receptive group was more dissatisfied with their bodies, especially weight, hip, abdomen, and body shape than unreceptive group. However, it had no significant effects on male adolescents' body satisfaction. Third, appearance instrumentality had many significant effects on male and female adolescents' appearance management behaviors. Especially, female receptive group had higher intention to perform professional care by a sliming club, beauty salon, and dermatology, and face plastic surgery than unreceptive group.

Objectives: The purpose of this study is to report a case of a plexiform neurofibroma (PNF) in the pelvic region treated with sweet bee venom (SBV) and mountain ginseng pharmacopuncture (MGP). Methods: A 16-year-old girl was diagnosed as having PNFs, neurofibromatosis type 1, 10 years ago and she had surgery three times to remove the benign tumors, but the growth of the PNFs continued. She has been treated in our clinic with SBV and MGP two times per month from March 2010 to April 2014. SBV was injected intra-subcutaneously at the borders of the PNFs in the pelvic region, and MGP was administrated intravenously each treatment time. Results: The growths of the PNFs occurred rapidly and continued steadily before treatment. Since March 2010, she has been treated in our clinic, and the growths of the PNFs have almost stopped; further-more, the discomfort of hip joint pain has been reduced, and her general condition has improved. Conclusion: We cautiously conclude that SBV and MGP treatment has some effects that suppress the growth and the spread of the PNFs in this patient.
