This experiment was designed to investigate the analgesic effect of non-invasive electroacupuncture treatment on femoral head osteotomy in dogs. Twelve dogs were divided into 3 groups in this experiment. Electroacupuncture group was non-invasively electrostimulated in Huan Tiao (GB-30) acupoint for 10 minutes by 4.5V, 5Hz for 10 days. Medication group was treated with carprofen (4mg/kg, P.O.) for 10 days. Control group was not treated. Each group was pre-operatively and post-operatively scored by using VAS (Visual Analogue Scale), SDS (Simple Descriptive Scale), NRS (Numerical Rating Scale), and measured serum cortisol levels. The results of VAS, SDS and NRS in electroacupuncture and medication groups were better than those of control group. And, the results of electroacupuncture group were better than those of medication group since 6th day after osteotomy in pain management(p<0.05). But, there were no significances in serum cortisol level among 3 groups. In conclusion, non-invasive electroacupuncture treatment showed sufficient analgesic effect on postoperative pain management after femoral head osteotomy, and VAS, SDS, and NRS scoring system would be adapted in evaluation of pain management.

This study was performed to evaluate the postoperative heating process according to lameness degree, swelling, and muscle atrophy after femoral head and neck ostectomy on Retriever dogs with hip dysplasia and hindleg lameness. Femoral head and neck ostectomy (FHO) was performed for the repair of hip dysplasia in 4 Retriever dogs (5 hips) referred in veterinary medical teaching hospital of college of veterinary medicine, Konkuk University. Age (Mean $\pm$ SD) of patients was 10.3 $\pm$ 3.0 months (range,7 to 16 months) and body weight (Mean $\pm$ SD) was 28.2 $\pm$ 3.4 kg (range, 25 to 34 kg). After FHO, all cases are treated with carprofen (2.2 mg/kg, PO bid, tapering at interval 1-2 weeks) and physical therapy including passive range-of-motion exercises. In all cases, lameness degree was showed V at the next day after surgery, IV at 5 to 7 days, II-III at 30 to 35 days, II at 60 days, and I at 105 to 114 days. These results suggested that femoral head and neck ostectomy was able to be performed on large breed dogs with hip dysplasia and hindleg lameness.

Using FEM, we analyzed the stress changes on early osteonecrosis of femoral head as the necrotic area increases. A 3D FEM model of proximal femur was made from the CT scam data of fresh frozen adult proximal femur with the material properties from literature. The model consisted of 5994 elements and 5275 nodes. FE analyses were peformed using MSC/NASTRAN. At normal states, stress transmission is mainly along the primary compression trabeculae(PCT). Until 60% involvement of PCT with necrotic lesion, stress transmission is still along the remained PCT. When the PCT involvement is from 60% to 85%, stress transmission is along the PCT and margin of the necrotic lesion. When involvement is more than 85%, stress is mostly transferred to posterior part of femoral head.

목 적 : 직장암 방사선 치료 시 대퇴골두의 선량을 최소화하기 위해, 보편적인 치료방법인 3문 입체조형치료계획(3D Conformal radiation therapy)과 5문 입체조형치료계획 그리고 용적변조방사선치료(Volumetric Modulated Arc Therapy, 이하 VMAT) 계획의 유용성을 비교, 평가하고자 한다. 대상 및 방법 : 본원에서 21EX(Varian Medical Systems, USA)를 이용하여 치료 받은 직장암 환자 10명을 대상으로 3문, 5문 입체조형치료계획과 VMAT 전산화치료계획을 각각 세우고 이에 대한 선량분포를 비교분석하였다. 전산화 치료계획은 Eclipse(Ver 10.0.42, Varian, USA)를 이용하였으며, 선량계산을 위해 PRO3(Progressive Resolution Optimizer 10.0.28), AAA(Anisotropic Analytic Algorithm Ver 10.0.28) 알고리즘을 사용하였다. 3문 치료계획은 6MV POST field 와 15MV LT, RT field를 갠트리 각도 $0^{\circ}$, $270^{\circ}$, $90^{\circ}$로 구성하였고, 5문 치료계획은 6MV POST field와 15MV RAO, RPO, LAO, LPO field를 갠트리 각도 $0^{\circ}$, $95^{\circ}$, $45^{\circ}$, $315^{\circ}$, $265^{\circ}$ 로 환자 체표면을 감싸는 형태로 구성하였다. VMAT 치료계획은 갠트리 회전반경이 $360^{\circ}$인 1개의 ARC를 이용하여 수립하였다. 처방선량은 30회에 걸쳐 직장에 총 선량이 54Gy가 되도록 하였다. VMAT 치료계획시 최적화(Optimization) 과정에서 나타나는 선량 차이의 무작위성을 최소화하기 위하여 2회의 최적화와 선량계산과정을 거쳤으며 처방선량의 100%가 표적용적의 95%를 포함할 수 있도록 Plan normalization을 조절하였다. 각 치료 계획의 Total MU, 대퇴골두와 acetabular fossa의 최대선량, PTV의 H.I. (Homogeneity Index), C.I.(Conformity Index)를 평가 지표로 설정하였고, 전자영상유도장치를 이용하여 임상 적용 가능 여부 확인을 위한 IMRT verification Q.A. (Gamma test)를 실시하였다. 결 과 : Rt. femoral head 최대선량은 3문, 5문, VMAT 치료계획 순으로 평균 53.08 Gy, 50.27 Gy, 30.92 Gy를 나타냈다. 마찬가지로 Lt. femoral head 에서도 같은 순으로 평균 53.68 Gy, 51.01 Gy, 평균 29.23 Gy를 나타냈다. Rt. Aceta fossa 의 최대선량은 3문, 5문, VMAT 치료계획 순으로 평균 54.86 Gy, 52.40 Gy, 30.37 Gy의 값을 보였다. Lt. Aceta fossa에서 또한 같은 순으로 평균 54.90 Gy, 52.77 Gy, 평균 31.79 Gy를 나타내어, both femoral head 와 aceta fossa의 최대선량이 3문, 5문, VMAT 치료계획 순으로 높았다. PTV에 대한 H.I.는 모두 서로 비슷한 결과를 나타냈고, C.I.는 3문, 5문, VMAT 치료계획 순으로 평균 1.64, 1.48, 평균 0.99로 VMAT 치료계획이 가장 낮은 것으로 나타났다. Total MU는 VMAT 치료계획이 3문과 5문 치료계획에 비해 각각 평균 124.4MU, 299MU 더 많이 사용하는 것으로 나타났다. VMAT 치료계획에 대한 IMRT verification Q.A. 결과 2mm / 2%, Gamma pass rate 90.0% 기준을 모두 초과하여 통과하였다. 결 론 : VMAT 치료계획은 3D 치료계획과 비교하여 대부분의 평가지표에서 우수한 것으로 나타났다. 특히 대퇴골두의 선량을 크게 감소 시켰으며, 저선량 영역에서는 소장이 받는 선량이 증가 하였으나 오히려 고선량 영역에서는 우수한 선량분포를 보였다. 하지만 VMAT을 지원하지 않는 장비와 치료계획 시 추가되는 Contouring, 그리고 정도관리에 관한 수고 등의 현실적인 제약 때문에 VMAT 치료계획을 선택하기 어려운 경우가 있을 수 있다. 5문 치료계획은 기존 3문 치료계획에 비해, 추가적인 문제에 구애받지 않고 대퇴골두의 선량을 줄일 수 있는 장점이 있다. 따라서 각 병원 상황에 맞게 치료계획을 선택하여 방사선 치료 효과를 높인다면, 직장암 환자의 효율적인 방사선치료 및 생존 기간의 연장뿐만 아니라 삶의 질 향상에도 도움이 될 것으로 판단한다.

Objectives : To investigate contributing degree of other factors except pelvic tilting to F.L.L.D by analizing with Gonstead technique on the correlation between femur head height discrepancy on the standing pelvic AP view and F.L.L.D caused by pelvic tilting. Method : We analysed standing pelvis AP X-ray of 70 patients who had visited at the department acupunture and moxibustion in Conmaul oriental medical hospital, during May, 1st, 2004 - July, 30th, 2004, with low back pain or lower extremity pain. We excluded the person with any past history of polio, genetic defect, malunited fracture, growth plate injury, infection and overgrowth attributable to hemangioma, or arteriovenous fistula. Results & Conclusion : The functional leg length discrepancy caused by pelvic tilting and femur head height difference had no statistical difference(p=0.132) but poorly correlated(Pearson ${\nu}=0.05$). In the 94.28% of subjects, the femur head height difference wasn't in accord with F.L.L.D. caused by pelvic tilting. In 47.14% of subjects were expected to have over $3^{mm}$ of leg length discrepancy after pelvic adjustment. The mean of measurement difference between two methods was $3.76{\pm}3.12^{mm}$ and the range was $0{\sim}11.4^{mm}$. Consequently, we must consider not only functional leg length discrepancy caused by pelvic tilting but also anatomical leg length discrepancy, misalignment of ankle, knee or hip joint etc.

PURPOSE: The aim of the study was to investigate the relationships among the hip joint passive range of motion (ROM) and femur head anterior glide (FHAG) mobility on the gait ability in patients with post-stroke hemiparesis. METHODS: The participants were 37 patients (30 male, 7 female) living in Daejeon. The ROM of the hip joint was measured by using goniometry and the FHAG mobility was measured by using the Prone Figure-4 test. The walking ability was assessed by using the 10m walk test (10MWT), and the 6-min walk test (6MWT). RESULTS: The FHAG was negatively correlated with hip extension (r=-.554, p<.05) and flexion (r=-.337) on the affected side as well as with hip extension (r=-.480), abduction (r=-.361), and adduction (r=-.426) on the non-affected side (p<.05). The gait ability was correlated with the hip joint external rotation on the non-affected side (p<.05), but showed no significant correlation with the hip ROM on the affected side (p>.05). CONCLUSION: This study provides evidence that in patients with post-stroke hemiparesis, the FHAG mobility might be correlated with hip extension. Based on these results, the FHAG mobility may be used to determine the hip extension in patients with post-stroke hemiparesis.

Progress in medical science and cell biology has resulted in the transplantation of human cells and tissues from on human into another, facilitating reproduction and the restoration of form and function, as well as enhancing the quality of life. For more than 40 years, society has recognized the medical and humanitarian value of donation and transplanting organs and tissues. The standard operating procedures of hard tissues reflect the collective expertise and conscientious efforts of tissue bank professionals to provide a foundation for the guidance of tissue banking activities. Procurement of allograft tissues from surgical bone donors is a part of tissue banking. During the past decades the use of bone allografts has become widely accepted for the filling of skelectal defects in a variety of surgical procedures. In particular in the field of orthopaedic and oral and maxillofacial surgery the demand for allografts obtained from either living or post-mortem donors has increased. Hospital-based tissue banks mainly retrieve allografts from living donors undergoing primary total hip replacement for osteoarthritis or hemi arthroplasty for hip fractures and orthgnatic surgery such as angle reduction. Although bone banks have existed for many years, the elements of organized and maintaining a hospital bone bank have not been well documented. The experience with a tissue bank at Korea Tissue Bank(KTB) between 2001 and 2004 provides a model of procurement, storage, processing, sterilization and documentation associated with such a facility. The following report describes the standard operating procedures of hard tissues such as femoral head obtained from living donors.
