We surveyed the wearing characteristics of hip protectors. The problems of existing hip protectors were identified and the directions for improvement were presented. The evaluation of wearing characteristics was conducted on the 100 elderly women (60 to 85 years) with 5 types of hip protector. The questionnaire was composed of history and characteristics on falling, hip protector acceptance, preference, use characteristics and improvement requirements. The result of wearing characteristic evaluation indicated that 52% of the subject experienced falling in winter. Incidents resulting from falling occurred: outdoors (74.5%), bathroom (10.9%), and kitchen (5.5%). Body parts to be protected were in several areas: 35.6% for lumbar, 26.9% for hip joint, and 15% for hip bone. Participants prefer a belt B type design at a rate of 56.9% because it provided a sense of stability by clinging to the body and upholding the waist. Belt B type was the most appropriate in terms of fit, allowance, mobility, and design except pad thickness. To reduce the risk of hip fracture, hip protector needs to be designed in consideration of user's type of fall and body shape. The pattern and size of a hip protector has to be improved in regards to the amount of discomfort. An objective evaluation is needed for the ergonomic design of a hip protector based on and analysis of 3D body image of the elderly and the shock-absorbing quality of pad.

This study analyzes changes in the knees, hips, and hip joint length according to the different angles of bending knees by 45°, 90°, and 135° respectively for knees, hips, and the hip joint that have high fracture rates when falling down. The research subjects were 10 elderly women in their 60s (or older) that obtain data collected through direct measurement. For analysis, the study drew a diagram of elongation and shrinkage based on changes and change rate from a straight posture (0°) and conducted a statistical analysis on differences of body surface length by zone according to movements. The more the knees were bent, the vertical surface length in front of the knees, the horizontal surface length above the knee line, the horizontal body surface length below the knee lines on the back, and the vertical surface lengths between front side lines and the side lines increased; however, the vertical surface length on the back decreased. For the hip joint, the difference in the vertical surface length was more distinctive when compared to the horizontal. Finally, the horizontal surface length increased below the hips and the vertical surface length increased in most areas except the sidelines and the front. The result of the change in body surface length according to the movements of this study can be utilized in the development of the motion-variable protector.

A wild Whooper swan (Cygnus Cygnus) with limping due to an injured left pelvic limb in an accident was rescued on the seashore and transferred to the Jeju Wildlife Rescue Center on November 23rd, 2020. On physical examination, its body condition score was 1 out of 5 due to starvation and dehydration. The left coxofemoral joint was also examined by careful palpating and estimating the damage. Moderated soft tissue swelling and crepitus surrounding the hip joint were confirmed. Radiography and computed tomography (CT) were used together for an accurate diagnosis of the joint. By radiographs readings, it was difficult to accurately confirm the condition of the proximal femur due to superimposition of the synsacrum and internal organs. However, signs such as avulsion fracture of the femoral head and a few fragments around the joint were revealed by CT imaging. Besides, through three-dimensional (3D) image analysis of CT, the dislocated area and condition of the left hip joint could be accurately and easily confirmed. The diagnostic process showing in this paper could be used as a good reference for diagnosing coxofemoral joint luxation in wild swan.

Purpose: Internal fixation using compression hip screws (CHS) and traction tables placing patients in the supine position is a gold standard option for treating intertrochanteric fractures; however, at our institution, we approach this treatment with patients in a lateral decubitus position. Here, the results of 100 consecutive elderly (i.e., ${\geq}45$ years of age) patients who underwent internal fixation with CHS in lateral decubitus position are analyzed. Materials and Methods: Between March 2009 and May 2011, 100 consecutive elderly patients who underwent internal fixation with CHS for femoral intertrochanteric fracture were retrospectively reviewed. Clinical outcomes (i.e., Koval score, Harris hip score [HHS]) and radiographic outcomes (i.e., bone union time, amount of sliding of lag screw, tip-apex distance [TAD]) were evaluated. Results: Clinical assessments revealed that the average postoperative Koval score decreased from 1.4 to 2.6 (range, 0-5; P<0.05); HHS was 85 (range, 72-90); and mean bone union time was 5.0 (range, 2.0-8.2) months. Radiographic assessments revealed that anteroposterior average TAD was 6.95 (range, 1.27-14.63) mm; lateral average TAD was 7.26 (range, 1.20-18.43) mm; total average TAD was 14.21 (range, 2.47-28.66) mm; average lag screw sliding was 4.63 (range, 0-44.81) mm; and average angulation was varus $0.72^{\circ}$(range, $-7.6^{\circ}-12.7^{\circ}$). There were no cases of screw tip migration or nonunion, however, there were four cases of excessive screw sliding and six cases of varus angulation at more than $5^{\circ}$. Conclusion: CHS fixation in lateral decubitus position provides favorable clinical and radiological outcomes. This technique is advisable for regular CHS fixation of intertrochanteric fractures.

It is well defined that osteoporosis is an age related disorder and associated with decreased bone mass. It is one of the most important disease lacing the aging population because of its association with fracture of the hip, vertebrae and distal radius. The disease provoke a significant economic burden and major public health problem of an elderly. The life-time risk of hip fracture in white women is approximately 15% which is equal to the combined risk of breast, uterine, and ovarian cancer. Despite its deleterious effect on women's health, knowledge of the epidemiology of osteoporosis in Korea is only beginning. 1970 in Korea has non as the crossover period between the chronic and an Infectious diseases. As the result, the infant mortality declined and an elderly population in Korea increased significantly in the past decade, The average life expectancy of women in Korea is now about 75 years. Thus, the majority of Korean women will spend approximately one-third of their life in the postmenopause state. Therefore, better understanding of bone metabolism and fracture incidence in Korean population is a great interest for the medical community as well as for public health. Currently, no population based epidemiologic data are available to support the incidence of osteoporotic fractures in Korea. However, available data suggest that significant declining of bone mineral density (BMD [g/$cm^2$]) has been occurring in Korean women after menopause. In same population, peak BMD was observed around 33-39 years of age and continue to decline thereafter. An accelerated bone losses occur after the menopause and the average loss is approximately 13% within 15 years from the menopause. The incidence of fracture was highly correlated with an age and bone mineral density. The mean age of menopause in Korean women was 47 years and this age appears to getting younger when analyzed by the birth cohort. An earlier menopausal age and increase life expectancy place Korean women at increase risk for osteoporosis and bone fracture. Korean or Asian women are no longer protected from the risk of bone fracture. Therefore, an early prevention or intervention schemes are essential before the outbreak of osteoporosis and/or fracture occurs in Korean or Asian women.

Radiographic findings of degenerative joint disease (DJD) in the coxofemoral joints were studied in 108 dogs referred to Veterinary Medical Teaching Hospital, College of Veterinary Medicine, Seoul National University. Radiographic findings were identified with a extended ventrodorsal projection. Clinical signs such as pain in the affected joint, exercise intolerance, lameness, crepitation on flexion and extension of the joint and decreased range of motion, were shown in 40% and radiographic changes of bilateral coxofemoral joints were identified in 69% of a group of dogs. There are no sex predilections. Thirty-seven dogs were diagnosed as canine hip dysplasia (CHD; 10 cases), avascular necrosis of the femoral head (Legg-Calves-Perthes disease [LCPD]; 12 cases), fracture of the acetabulum (1 case), luxation(10 cases) and subluxation (15 cases), however, luxation and subluxation were identified in 11 dogs affected with CHD and LCPD. Causes of DJD in others (71case) were not identified. Radio-graphic findings identified included osteophyte formation at the attachment of the joint capsule (70%), sclerosis of the subchondral bone of the cranial acetabular edge (47%), remodeling of the femoral head (34%), thickening of the femoral neck(31%), perichondral osteophyte formation (31%), joint laxity (30%) and so on. All of the dogs diagnosed as CHD were large breed such as Retriever, Germain Shepherd, and Weimaraner and their age was under 1 year. This condition occurred bilaterally in 70% of affected animals. Dogs diagnosed as LCPD were young (under 1 year), small breed dogs. The incidence of LCPD is greater in Yorkshire Terrier, Miniature Pinscher and Poodle. This condition occurred unilaterally in 67% of affected animals. Clinical signs of dogs with unknown cause were shown in 15% and this condition occurred bilaterally in 75% of affected animals. Radiographic findings varied with patient's age and breed, however, the most common finding was osteophyte formation at the attachment of the joint capsule.

Total hip replacement is a crucial intervention for patients with fractured hips who face challenges in natural recovery. The design of durable prostheses requires a comprehensive understanding of the natural processes occurring in bone. This article focuses on static loading analysis, specifically during stumbling activity, aiming to enhance the longevity of prosthetic implants. Three distinct implants, Charnley, Osteal, and Thompson, were selected for a detailed study to determine the most appropriate model. The results revealed critical insights into the distribution of Von Mises stresses on the components of femoral arthroplasty, including the cement, implant, and cortical bone. Furthermore, the examination of shear stress within the cement emerged as a pivotal aspect for all three implants, playing a crucial role in evaluating the performance and durability of hip prostheses. The conclusions drawn from this study strongly suggest that the Thompson model stands out as the most suitable choice for hip joint implants.
