Background : The purpose of this study was to investigate the effects of the kinesiologic factors of gait on symmetric load. Methods : The subjects were consisted normal 33 persons (10 males and 23 females). The kinds of weight of the bag was 0kg, 5kg and 7kg. The kinesiologic factors of gait measured by three dimensional motion analysis system and callibration marker. Callibration was ASIS, hip greater trochanter, knee lateral epicondyle on sagittal plane, ankle lateral malleolus on sagittal plane, toe 5th phalange. The changes kinesiologic factor were analyzed using one way ANOVA with SPSS 21.0 package program. Results : The weight of the bag was statistical significance on change of hip joint and knee joint(p<.05). The weight of the bag was no significance on change of ankle joint(p>.05). The right and left of the lower limbs was no significant(p>.05). Conclusion : This research provides weight of bag for the gait. This study showed that symmetric load does affect kinesiologic factors of gait. This indicates that there is an interaction that plays a crucial roles in the weight of bag and kinesiologic factors of gait.

We investigated the structural geometry of thirty-eight Korean femurs. The purpose of this study is to identify major geometrical differences between Korean femurs 3nd others that we believe belong to Caucasians so that we would be able to get insights into the femoral component design that fits Asians including Koreans. We utilized computerized tomography (CT) images of femurs extracted from cadavers. The CT images were transformed into bitmap data by using a film scanner, and then analyzed by using a commercially available software called Image v.1.0 and a Macintosh IIci computer.The resulting data were compared with already published data. The major results show that the geometry of the Korean femurs is significantly different from that of Caucasians: (1) the anteversion angle and the canal flare index are greater by the amount of approximately 8˚ and 0.5, respectively, (2) the shape of the isthmus cross section is more round, and (3) the distance between the teaser trochanter and the proximal border of the isthmus is shelter by about 15 mm. The results suggested that the femoral component suitable for Asians should be different from the currently-used components designed and manufactured mostly by European or American companies.

Two standard methods of cane length measurements were compared to find which methods really achieve the elbow flexion of 20 degrees to 30 degrees Twenty-four patients with hemiplegia who were ambulatory participated in this study. Method I : Length of the cane measured from the floor to the top of the greater trochanter. Method II : Length of the cane measured from the floor to the distal wrist crease with the arm at the side. Using an adjustable cane, each individual was fitted according to the two methods, and elbow angle was measured after each adjustment. The elbow angle according to Method I and Method II was $46.4{\pm}20$, $44.3{\pm}12.2$, respectively. No significant difference was found in the elbow angle or the cane length between the two methods. Of the 24 participants, 5(20.8%) measured according to method I and 3(12.5%) measured according to method II showed the elbow angle between 20 degrees and 30 degrees. These low predictive rates of agreement between ideal cane length and actually achieved elbow angle showed that these two methods which have conventionally been accepted as a standard to measure ideal cane length need to be revised through further research.

The purpose of this study was to examine the acute effects of nerve mobilization, static stretching, and hold-relax on the flexibility of hamstring muscles and their surface electromyographic (EMG) responses to passive stretches in poststroke hemiparesis. This study was a randomized cross-over trial. Fourteen subjects received three treatment sessions in random order with each consisting of ten repetitions. The treatment sessions included nerve mobilization, static stretching, and hold-relax. The treatment sessions were held at least 24 hours apart to minimize any carryover effect. The outcome was measured by the distance between the greater trochanter and lateral malleolus and hamstring EMG activity during passive knee extension stretching. Repeated-measures analysis of variance showed significant changes in hamstring flexibility and EMG activity in main effect of time pre, post and followup (p<.05). However, no significant differences occurred among the three stretching techniques. No technique was consistently found to be superior. The three stretching techniques in this study make it difficult to determine the most effective technique. Therefore, clinicians use nerve mobilization of effective stretching techniques with other stretching techniques.

PURPOSE: The purpose of this study was to find out variations in body posture by using the baby carrier at the front side and back side. METHODS: Thirty two healthy and young female who will bring up infants and had no musculoskeletal disorders of neck, lumbar and low limb were recruited for this study. They were each marked about ears of tragus, cervical 7th, acromion anterior end, anterior superior iliac spine, posterior superior iliac spine, greater trochanter and lateral malleolus as landmarks to measure variations of body posture when they carry infants at the front side and back side. Landmarks were regarded as the creteria in order to measure NeckFlexion angle(NF), Foreward shoulder angle(FSA), Pelvic tilt(PT), Sway angle(SA), Head displacement(HD) and Scapular displacement(SD). Variations in body posture were measured from the neutral position to the front and back side by using Image J. RESULTS: There were significance level (p<.05) in NF, PT, SA, HD and SD except for FSA in two different side. CONCLUSION: The results of this study indicate that each of the using ways of baby carrier for baby care was influenced postural responses of young women. therefore, it could be considered to apply to women who have abnormal body posture in order to minimize musculoskeletal disorders.

Piriformis syndrome is a syndrome of low back and leg radiating pain thought to be due to a chronic contracture of the piriformis muscle that causes irritation of the sciatic nerve. The piriformis muscle is a flat pyramidal muscle, an external rotator and abductor of the hip, originating from the front of the sacrum and inner aspect of the sacroiliac joint, then passes laterally out of the sciatic notch to attach posteriorly to the greater trochanter of the femur, the sciatic nerve passes between the two bellies of the muscle. Mechanical irritation of the sciatic nerve by an inflammatory reaction of the piriformis muscle and its fascia at this pelvic level causes pain to radiate in the dermatomal regions of the nerve roots similar to that disk entrapment. diagnosis of piriformis syndrome is made primary on the basis of history and clinical examination. The incidence is considerably higher in women, with the reported ratio of women to men of 6:1. These patients frequently present with associated symptoms of pelvic pain and/or dyspareunia. Symptoms are usually unilateral but occasionally be bilateral. We had a 42 year-old woman patient with low back and left leg radiating pain and dyspareunia treated by caudal steroid and local anesthetic.

Background : Osteopenia has been recognized as one of potential complication of chronic liver diseases. Its correlation with hepatits B virus(HBV) carrier, however, has not been reported. Thus this study was aimed to clarify the relationship between the osteopenia and HBV carrier. Methods : Bone densities in 192 HBV carrier women and 200 healthy women were measured; the lumbar spine and three sites of the proximal femur(neck, Ward's triangle, greater trochanter) by dual-photon absorptiometry. And liver function tests(AST, ALT, Albumin, GGT, ALP) were also performed. Results : Bone densities at the four sites measured, were significantly correlated with one another(r=0.34 to 0.99, P<0.01). Compared with control group, HBV carriers had significant decreases in bone densities of femur(P<0.05), particularly marked at Ward's triangle. A negative correlations between bone densities and serum total alkaline phosphatase were also found(r=-0.44, P<0.01). Conclusions : Osteopenia was more prevalent in HBV carrier, particularly in the groups before-fifties. Serum total alkaline phosphatase was higher in those with reduced bone densities Thus measurement of bone densities seems to be necessary in female HBV carriers.

Purpose : This study was performed to evaluate the effects of a prolonged a $30^{\circ}$ side-lying position on comfort and skin condition by applying the trunk maintenance repositioning method, which can keep the $30^{\circ}$ side-lying position effective for preventing pressure ulcers. Method : Fifty-four healthy nurses working at a general hospital in Seoul were randomly assigned to an experimental group (n=27) or a control group (n=27) and assumed a position of lying on their right or left side for two hours. The trunk maintenance repositioning method was applied to the experimental group using the pillow made by the researcher, while the original repositioning method was applied to the control group using the regular pillow from the subject hospital. Participants' posture angles, comfort, and skin condition were measured at the time of the intervention, as well as at one and two hours after the intervention. Results : There was no statistically significant difference in position angle, comfort, skin condition change, or sacrum and greater trochanter pressure change between the two groups over time. Conclusion : It is necessary to review the method and frequency of change of position in each hospital. In addition, a proper position changing pillow should be developed in consideration of patients' various body shapes.

Pressure sore is an area of ulceration and necrosis of the skin and underlying tissues usually occuring over the bony prominences of the body after prolonged or often repeated pressure. We reviewed and summarized the published articles and treatise on the treatment of pressure sore. The results were as follows : 1. Pressure sore occur due to prolonged or often repeated pressure. So it is better than decubitus ulcer that is called pressure sore. 2. The most common lesions of pressure sore are sacrum, ischial tuberosity, greater trochanter. 3. The cause of pressure sore are change of comprehension. urine, moisture, change of the ability of activity and exercise, shearing force. 4. The elements to influence on wound healing are collagen accumulation velocity, nutrition condition, Vitamine C, copper, iron. oxygen pressure, steroids, cell-toxic drug, radiation. 5. Non-operative treatments are managements of skin such as avoiding consistant pressure, dressing, preventing moisture, understanding patient and protecter, preventing spasm, improvement of systemic nutrition condition. 6. Operative treatements are debridement, suture, skin transplantation, muscle flap and musculaocutaneous flap surgery. Recently V-${\Gammer}$ advancement surgery in use of muscle and musculocutaneous flap is generally maded. 7. Complications of post-operation are wound rupture, infection, disappearance of transmitted skin, necrosis of flaps.

Purpose: The purpose of this study was to determine whether the direct anterior approach (DAA) can be applied to hemiarthroplasty for treatment of unstable femoral intertrochanteric fractures in elderly patients. Materials and Methods: We conducted a retrospective review of 34 cases (34 patients) who underwent bipolar hemiarthroplasty using a DAA from February 2019 to April 2020. The mean age of the patients was 82.68 years (range, 67-95 years). A cementless distal fixation hip system was used in all cases. Operation time, total amount of blood loss, intraoperative and postoperative fractures, infections, and reoperations were measured. The patients performed weight-bearing walking as tolerated immediately after surgery. Measurement of migration of the greater trochanter (GT) and progressive subsidence of the femoral stem was performed using follow-up radiographs. Results: The mean operative time was 83.50 minutes (range, 60-120 minutes). The mean amount of bleeding was 263.53 mL (range, 112-464 mL). Walking started a mean of 3.03 days (range, 3-4 days) after surgery. There was no case of progressive migration of the GT more than 5 mm even though it was not fixed. There were no cases of infection, dislocation, or reoperation. Conclusion: Bipolar hemiarthroplasty using the DAA for treatment of unstable femoral intertrochanteric fractures could be considered a useful option that provides many advantages in elderly patients.
