In femoral neuropathy, the femoral nerve is compressed or ischemic. Patients with femoral neuropathy experience muscle atrophy, difficulty flexing the hip joint and extending the knee, decreased sensation of the lower extremities, and loss of patellar tendon reflex. The prognosis of femoral neuropathy is reported to vary, as it takes several days to several months for neurological abnormalities to resolve. We describe a case of a 58-year-old female with a diagnosis of severe femoral neuropathy and complaints of motor weakness and hypoesthesia. The patient underwent combined Western-Korean medicine treatment. The Toronto Clinical Neuropathy Scoring System, Overall Neuropathy Limitations Scale, and Berg Balance Scale were used as evaluation tools during the treatment period. The combined Western-Korean medicine treatment led to a significant improvement in symptoms in this patient with severe femoral neuropathy where the cause was unclear and the prognosis was expected to be poor.

We report a successful right,sleeve pneumonectomy using femoro-femoral bypass on a 26-year-old woman with severe carinal and lower tracheal stenosis of tuberculous origin. Omental graft on the anastomotic site was added, There was no specific postoperative complication and postoperative bleeding was minimal.

We developed a method for the solid angle estimation of acetabular coverage of the femoral head in 3D space. The superior half of the femoral head is modeled as part of a sphere. And the tangent lines connecting from a set of points of the acetabular outline to the center of the fitted sphere are obtained. The lines passthrough the unit sphere whose center is the same as that of the femoral head. The interesecting points form a boundary on the unit sphere. With the points on the unit sphere, we calculate the covered area of the femoral headand estimate the solid angle. Solid angle is defined asthe suface area within the boundary on the unit sphere. In this measurements, the solid angle of normal subjects is on an average 4.3(rad) and the corresponding acetabular coverage is 68%. Unlinke the conventional methods, this solid angle estimation shows real 3D acetabular coverage.

After ACL reconstruction. abrasion or wear of graft appeared frequently because of contact stresses between femoral tunnel and ACL. To minimize these problems. optimal shape of femoral tunnel is necessary. In this study. we evaluate friction force by degree of wear due to abrasion of soft tissue and develop 3-dimensional FEM model using ANSYS 5.5.1 version to analyze stress growths between femoral tunnel and ACL, We conclude that femoral tunnel angle must be slacked parallel to tunnel direction to minimize contact stress.

Gait control capacity for most trans-femoral prostheses is significantly different from that of a normal person, and training is required for a long period of time in order for a patient to walk properly. People become easily tired when wearing a prosthesis or orthosis for a long period typically because the gait angle cannot be smoothly adjusted during wearing. Therefore, to improve the gait control problems of a trans-femoral prosthesis, the proper gait angle is estimated through surface EMG(electromyogram) signals on a normal leg, then the gait posture which the trans-femoral prosthesis should take is calculated in the neural network, which learns the gait kinetics on the basis of the normal leg's gait angle. Based on this predicted angle, a postural control method is proposed and tested adaptively following the patient's gait habit based on the predicted angle. In this study, the gait angle prediction showed accuracy of over $97\%$, and the posture control capacity of over $90\%$.

Recent clinical studies have shown that computer navigation for total knee arthroplasty (TKA) provides improved component alignment accuracy. However, femoral stress fracture after computernavigated TKA have been reported due to the pin hole and we hypothesized that osteoporosis would be one of the key factors in pin hole fracture after computer-navigated TKA. We investigated the von-Mises stress around the femoral pin-hole for different elastic modulli and ultimate stresses and four different pin penetration modes to understand the aging effect on femoral stress fracture risk after computer-navigated TKA by finite element analysis. In this study, aging effect was shown to increase the femoral stress fracture risk for all pin penetration modes. Especially, aging effect was shown dramatically in the transcortical pin penetration mode.

Objectives: The purpose of this study is to report the clinical effects of oriental medical treatment on delayed healing in femoral shaft fractured child. Methods: We treated the patient with herb medicine named Kamiboatang and Pyritum. Child took Kamiboatang and Pyritum for 2 months, and Kamiboatang for 1 month. After 3 months treatments, we examined the case with radiological findings. Results: The patient's delayed femoral shaft fracture was improved after 3 months oriental medical treatment. Conclusions: This case showed that oriental medical treatment on delayed healing in femoral shaft fractured child was effective. To prove the effectiveness of Kamiboatang and Pyritum, the more clinical study of Oriental medical treatment for this case might be also needed.

Ipsilateral fractures of proximal femur with shaft and condylar region are very rare. Current concept of management is based on fixation of each fracture as independent entity using separate fixation modalities for proximal and distal parts of femur. However, we considered that antegrade femoral nailing with cephalomedullary screw fixation is a good option for ipsilateral multi-level femoral fractures. Here, we present an experience of satisfactory treatment for ipsilateral femoral neck fracture, subtrochanteric fracture, comminuted shaft fracture with supracondylar fracture following road traffic accident.

The measurement of the fermoral anteversion is an important factor in the practice of orthopedic surgery. The anteversion is measured by means of the axis of head and neck of the femur. In this study. widely used computed tomography method of measuring anteversion was tested on femoral necks of patients. Measurement by the manual method and image viewer of computed tomography to determine the anteversion of femoral head were carried out on both femurs. In January and February 2001, 30 patients 3 to 6 years of age were randomly selected from Seoul National University Hospital. the purpose of this paper was to introduce a new method to measure femoral anteversion angle utilizing image viewer program. This new method was more accurate and convenient than the conventional manual method. No significant difference was observed between the manual method and the image viewer measurement of femoral anteversion. In conclusion, image viewer program was statistically more reliable in determining the angle of the fermoral anteversion.

The Purpose of this study was ta investigate the change of bone density by Partial weight bearing and non-weight bearing exercise. Twelve female volunteers in good health (between 20 and 30 years of age) were studied as subjects. Subjects were divided into three groups; an experimental group 1(n =4 swimming group), group 2(n = 4 bicycle group) and control group=4. Before and after 11weeks(five times a week), the subjects were examined for change of bond density using a dual energy X-ray absorptiometry. The results were summarized as fellows T . There was increase in bone density of femoral neck in the group that swam but there was no difference in lumbar, femoral neck and femoral ward's triangle region (P<0.05) 2. There was increase in hone density of femoral ward's triangle in the group that swam but there was no difference in lumbar, femoral neck and femoral ward's triangle region(P<0.05) 3. After a aerobic exercise by partial weight bearing and non-weight bearing , there was no difference in the part of excessive muscle's exercise but there is the increase of the bone density in figures.
