The purpose of this study was to examine the effects of delirium prevention program in patients after hip joint surgey. A non equivalent control group post-test only design was utilized. Sixty four patients aged 65 and older who admitted to a surgical intensive care unit after hip joint surgery were assigned to either a experimental group (n=33) or a control group (n=31). The experimental group was provided with delirium prevention program consisting of orientation intervention, activity intervention, physiological intervention, nutritional intervention, sleep intervention, environmental intervention. Data were analyzed using ${\chi}^2-test$ and independent t-test. The experimental group showed lower incidence of delirium than the control group(${\chi}^2=7.048$, p=.008). The experimental group showed lower ICU stay and length of hospitalization than the control group although the difference was not statistically significant. Findings indicate that the dilirium prevention program is effective in reducing incidence of delirium in patients after hip joint surgery and delirium prevention program is recommended as a guide for the prevention of delirium.

One of the main purposes in the treatment of developmental dislocation of the hip is to achieve and maintain concentric, congruent, and stable reduction. The arthrogram performs an important role in the diagnosis and treatment of developmental dislocation of the hip. The arthrogram provides much information about the soft tissue status of the hip joint. Limbus and ligamentum teres is exactly evaluated so that we can plan the reduction and treatment before operation. Eighteen preoperative hip arthrograms of 17 children treated for developmental dislocation of the hip from 1992 to 1998 were reviewed. The limbus, ligamentum teres and transverse acetabular ligament were compared with the pathoanatomy seen at the time of open reduction. Arthrography proved to be reliable in identifying the limbus and ligamentum teres. So we recommend that arthrography must be performed before closed or open reduction. Also, we recorded the radiographic parameters: acetabular index, acetabular floor thickness, center edge(CE) angle of Wiberg, and Y-coordinate. The center edge(CE) angle of Wiberg obtained from arthrography was measured more accurately than from simple roentgenograms because the ossification of the femoral head was frequently located eccentrically in the developmental dislocation of the hip.

Simple radiography, CT and MRI were used for the diagnosis of the hip disease. However ultrasonography could be a good diagnostic tool for the lesion of tendons and bursae. Another advantage of ultrasonography is its usefulness for the follow-up of these lesions. Nowadays hip ultrasonography expanded the horizon to the follow-up study of total hip arthroplasty. However, the limitation of ultrasonography is that there is disparity in results according to the physician's experiences. In this article ultrasonographic findings of normal structures and pathologic lesions of the hip joint are introduced and explained briefly.

The biomechanics study of the hip is aims to understand and explore the dynamic principles of weight transfer through the hip joint. This basic science knowledge can be applied in a variety of areas, including degenerative joint diseases and hip replacement arthroplasty. In particular, understanding of the biomechanics of the hip has led to the development of materials, design and fixation of implants, and it can be applied in various areas, such as the selection of surgical methods and the location of the implant. Moreover, it is essential to have good knowledge of the biomechanics of the hip to achieve better clinical results for patients. Therefore, this paper introduces the basic knowledge and biomechanical characteristics of a normal hip and hip replacement arthroplasty, which are needed to approach the biomechanics of the hip.

Purpose: To compare and analyze the rate of prevention of two venous thromboembolism prophylaxis guidelines in patients with artificial joint arthroplasty and hip joint fracture. Proper prophylaxis for preventing thromboembolism in orthopedic surgery is significant because of this fetal complication. Materials and Methods: This study compared and retrospective analyzed the rate of prevention using the medical records and radiographs of patients who underwent orthopedic surgery from March 2009 to February 2011 according to the American College of Chest Physicians (ACCP) guidelines and from March 2012 to February 2014 according to the American Academy of Orthopedic Surgeons (AAOS) guidelines. Results: The guidelines for venous thromboembolism prophylaxis have been applied to patients with artificial joint replacement and hip joint fracture, the compliance rate of the ACCP guidelines was 56.0% before surgery, 67.0% after surgery with chemical prophylaxis, and 80.5% with mechanical prophylaxis. In addition, the compliance rate of the AAOS guidelines was 74.1% with chemical prophylaxis, and 88.3% with mechanical prophylaxis, which was higher than the ACCP guidelines. The compliance rates of mechanical and chemical prophylaxis before and after surgery of the ACCP guidelines, and the compliance rate of mechanical and chemical prophylaxis of the AAOS guidelines were compared and analyzed. The results revealed statistical significance (p<0.05) before and after total knee replacement arthroplasty and hip joint fracture internal fixation and total high risk orthopedic surgery. Conclusion: Raising the compliance rate of prophylaxis of venous thromboembolism in high risk orthopedic surgery is necessary and people should follow the guidelines for a unified direction depending on which situation they are in.

Developmental dysplasia of the hip broadly includes inadequate development of the hip joint involving the acetabulum or proximal femur, or both. Although ultrasonographic studies in neonates have greatly lowered the frequency of neglected or operatively treated cases, its sensitivity is less than desired. Hip dysplasia without subluxation is commonly diagnosed incidentally and strongly related to degenerative arthritis in females after the 4th decade. Hip dysplasia with subluxation shows symptoms through various periods, depending on its severity, especially for women with onset during pregnancy. A complete physical examination and early treatment for neonates are extremely important for obtaining satisfactory outcomes. To avoid underdiagnosis and to serve appropriate treatment on time, the authors recommend examining any suspicious hips in infants under two years of age. The study will discuss the diagnosis and primary treatment of developmental dysplasia of the hip.

Conventional total hip joint replacement(THR) surgery requires a long incision and long rehabilitation time. The stem used in THR is inserted into the cancellous bone of the femur where it plays the role of the artificial joint. Minimally invasive surgery(MIS) has been devised to reduce muscle damage to patients. In this study, a mechanical stem was developed on the basis of MISto reduce the incision length through the principle of the gear. The mechanical stem consists of six components. A prototypical model for a mechanical stem was fabricated using an acryl-based polymer, and its workability was confirmed. To actualize the mechanical stem, a three-dimensional Bio-CAD modeling technique was applied. The hip joint area based on computed tomography(CT) was reconstructed. The safety of the mechanical stem by applying more load than the weight of a man under virtual surgery environment conditions was confirmed by finite element analysis.

The objective of this study was to evaluate tire effects of modified triple pelvic osteotomy(TPO). The procedures of modified TPO were composed of two iliac osteotomies and a pubic symphysiotomy at a tittle. Medical records of modified TPO treatment on 36 dogs and of unilateral TPO on 7 dogs were reviewed on the basis of signalment, body weight, operation time, Healing time of osteotomy sites and complications from October 2002 to September 2004. The values of clinical status and hip dysplasia, Norberg angle, percentage of femoral head coverage and pelvic diameter from radiographs taken preoperative, immediately postoperative, 2, 4, 8, 12 and 24 weeks after operation, respectively, were measured. In .unilateral TPO, the dogs could start standing without assistance from $3.0\pm1.0days$ and walking from $8.3\pm0.6days$ (n=3). Mean clinical grade before and 24 weeks after surgery were $2.2\pm0.42$(n=6) and $3.5\pm0.7$ (n=2), respectively. Mean operation time was $107.3\pm38.9$ minutes (n=4). In modified TPO, the dogs were seen to staff standing without assistance from $4.9\pm3.7$ days and walking from $7.3\pm4.8days$ (n=25). Mean clinical grade before surgery and 24 weeks after surgery were $2.3\pm1.5$ (n=27) and $3.2\pm0.7$)(n=9), respectively. Postoperative clinical grade significantly improved against preoperative clinical grade (P<0.01). Mean operation time was $143\pm42.8$ minutes (n=24). This was shorter than time f3r twice unilateral TPO. By comparison with preoperative values, postoperative mean radiographic grade, percentage of femoral head coverage and Norberg angle measured at the recheck time point significantly increased (P<0.01). Mean postoperative pelvic diameter was significantly larger than preoperative pelvic diameter in modified TPO (P<0.01) but not in unilateral TPO. These results indicated that modified TPO was effective technique for the treatment of hip dysplasia in dogs.
