The purpose of this study was to observe the change of circumference, volume and strength of normal and operated lower extremities on 3rd, 7th, 10th, and 14th days of postoperation following THRA compared with their condition on preoperation day. Subjects consisted of 13 male and 7 female Patients operated with THRA between the age of 20 and 69 years with a mean age of 38.55(SD=15.1). Circumference of upper and lower leg was measured by tape, leg volume was determined according to formula (Moor & Thornton, 1987) with measurement of 8 circumferences of leg. Leg strength was measured by pressing the center of digital health meter in supine position. The results can be summarized as follows : 1. Circumference of operated thigh decreased significantly at 14 following THRA compared with preoperative value, while that of normal thigh decreased significantly at day 3, 7, 10 and 14 after THRA compared with preoperative value. 2. Circumference of midcalf in both operated and normal limb decreased significantly at day 3, 7, 10 and 14 following THRA compared with preoperative value. 3. Leg volume of operated lower limb decreased significantly at 10, 14 following THRA compared with preoperative value, while that of normal limb decreased significantly at day 7 & 10 after THRA compared with preoperative value.4. Leg strength of operated limb decreased significantly at day 3, 7, 10, 14 following THRA compared with preoperative value. No significant difference of normal leg strength was shown following THRA. 5. Circumference of midcalf differed significantly at day 14 after THRA between normal and operated extremity. From these results, it can be suggested that a decreased activity after THRA caused muscle atrophies in normal and operated extremity.

l. Objectives To analyse gait disturbance of patient who was operated Total Hip Replacement Arthroplasty(THRA). 'This study is reported to emphasize on psychological stability and balance of vital dynamics. 2. Methods This patient was treated by the remedy of Soyangin, who was diagnosed as Soyangin. We used visual analogue scale(V AS) for the assessment of Rt. femoral pain. 3. Results The patients operated THRA are needed not only rehabilitation of gait, but also psychological stability and balance of vital dynamics. 4. Conclusions We suggest that patients operated THRA are needed not only rehabilitation of gait, but also psychological stability and balance of vital dynamics.

THRA(Total Hip Replacement Arthroplasty) has been widely used for several decades as a viable treatment of otherwise-unsolved hip problems. In THRA surgery, cement mantle thickness is critical to long-term implant survival of femoral stem fixed with cement. Numerous studies reported thin or incomplete cement mantle causes osteolysis, loosening, and the failure of implant. To analyze the effect of femoral stem rotation on cement thickness, in this study, we select two most popular stems used in THRA. Using CAD models obtained from a 3D scanner, we measure the cement mantle thickness developed by the rotation of a femoral stem in the virtual space created by broaching. The study shows that as the femoral stem deviates from the target coordinates, the minimum thickness of cement decreases. Therefore, we recommend development of a new methodology for accurate insertion of a femoral stem along the broached space. Also, modification of the stem design robust to the unintentional movement of a femoral stem in the broached space, can alleviate the problem.

Resistance to thyroid hormone syndrome (RTH) is a genetic disease caused by the mutation of either the thyroid hormone receptor-β (THRB) gene or the thyroid hormone receptor-α (THRA) gene. RTH caused by THRB mutations (RTH-β) is characterized by the target tissue's response to thyroid hormone, high levels of triiodothyronine and/or thyroxine, and inappropriate secretion of thyroid-stimulating hormone (TSH). THRA mutation is characterized by hypothyroidism that affects gastrointestinal, neurological, skeletal, and myocardial functions. Most patients do not require treatment, and some patients may benefit from medication therapy. These syndromes are characterized by decreased tissue sensitivity to thyroid hormones, generating various clinical manifestations. Thus, clinical changes of resistance to thyroid hormones must be recognized and differentiated, and an approach to the practice of personalized medicine through an interdisciplinary approach is needed.

In this study, we would like to examine the effect of the location of the magnification marker and the change in the stitching range on the magnification marker and the expansion of the anatomical structure in the examination of femoral stitching radiation using the stitching technique, and to find out the usability of the femoral stitching radiation examination in the preoperative examination for THRA. The measured values measured by 5 researchers were summed and presented through descriptive statistics. When the position of the magnification marker was changed, the average value of the measured value was in the range of 113.54 to 113.90 mm. The anatomical structures of the femur were measured in the range of 57.24 to 57.78 mm, 27.20 to 27.56 mm, and 70.11 to 70.81 mm, respectively. This showed a similar deviation from the expansion rate of previous related papers using markers. Therefore, it is considered that femoral stitching X-ray examination using magnification markers can be used for preoperative examination for THRA.

To make a comparative analysis for clinical application of total hip replacement arthroplasty(THRA) using fluoroscopy, we have performed total hip replacement arthroplasty making 30 patients an object with general radiography and fluoroscopy respectively. The results are as follows : 1) Reexamination rate was 80% of patients and mean 3.9 sheets in the general radiography, where as it was 46.7% and 0.37 sheets in the fluoroscopy(p<0.01) 2) Add examination was 2 cases in the general radiography, but fluoroscopy was no add examination. 3) The total film sheet used was mean 10.16 in the general radiography and 6.73 in the fluoroscopy. 4) In the cause of reexmination and add examination, inaccurate position of patient accounted for 72.6% in the general radiography and poor exposure condition accounted for 45.5% in the fluoroscopy. Total hip replacement arthroplasty using the fluoroscopy decreased reexamination and add examination rate, for these reasons, this method was effective abatement of pain, exposured radiation dose, and examination time and so on.
