Purpose: Elderly patients with degenerative diseases undergo treatment for the hip and spine; these patients present with various symptoms. This study focused on patients with residual symptoms, predominantly pain, even after receiving treatment for their spinal lesions. Materials and Methods: Patients who underwent total hip arthroplasty (THA) between 2016 and 2022 at a single tertiary hospital were included in the study. Of the 417 patients who underwent primary THA, a retrospective review of 40 patients with previous lesions of the spine was conducted. Patients were stratified to two cohorts: Patients with symptoms related to the spine (Group A), and those with hip-related symptoms (Group B). Preand postoperative comparisons of groups A and B were performed. Results: Improvements in patients' symptoms were observed in groups A and B after THA. In Group A, the mean preoperative visual analog scale (VAS) score was 5.10±0.876, which showed a postoperative decrease to 2.70±1.767. In Group B, the mean preoperative VAS score was 5.10±1.539, which showed a postoperative decrease to 2.67±1.493. Conclusion: According to the findings, promising results were achieved with THA in treatment of debilitating diseases of the hip for both the prognosis of the disease, as well as the patients' symptoms. In addition, in some cases elderly patients with dual pathologies underwent treatment for spinal lesions without performance of any evaluation related to the hip. Thus, evaluation of a patient's hip must be performed and performance of THA in patients with symptoms even after treatment of spinal lesions is recommended.

Purpose: To assess current practice in the treatment of osteoporosis in patients who underwent treatment for hip fracture in South Korea. Materials and Methods: A survey of 97 members of the Korean Hip Society, orthopedic hip surgeons who administer treatment for hip fractures in South Korea, was conducted. The survey was conducted for assessment of demographic data and perceptions regarding the management of osteoporosis in patients who have undergone treatment for hip fracture. Analysis of the data was performed using descriptive statistical methods. Results: The majority of participants were between the age of 41 and 50 years, and 74% were practicing in tertiary hospitals. Testing for serum vitamin D levels (82%) was the most commonly performed laboratory test. Calcium and vitamin D were prescribed for more than 80% of patients by 47% and 52% of participants, respectively. Denosumab was the most commonly used first-line treatment option for osteoporosis in hip fracture patients. Bisphosphonate was most often perceived as the cause of atypical femoral fractures, and the most appropriate time for reoperation was postoperative 12 months. Teriparatide was most preferred after cessation of bisphosphonate and only prescribing calcium and vitamin D was most common in high-risk patients for prevention of atypical femoral fracture. Conclusion: The results of this study that surveyed orthopedic hip surgeons showed that most participants followed the current strategy for management of osteoporosis. Because the end result of osteoporosis is a bone fracture, active involvement of orthopedic surgeons is important in treating this condition.

PURPOSE: This study intended to verify whether there was actual correlation between weight-bearing asymmetry and a limitation in hip joint rotation range in patients with low back pain. METHODS: Thirty five low back pain patients voluntarily participated this study. For each participant, hip joint medial rotation symmetry rate and the weight-bearing symmetry rate were calculated. The correlation between the two variables was investigated. RESULTS: A decrease in the left hip joint medial rotation range of motion (ROM) was observed more often than a reduction in the right hip joint medial rotation ROM. However, similar number between right and left side was observed in ground reaction force more weighted. The coefficient between the passive hip joint medial rotation symmetry rate and the weight loading symmetry ratio was -0.19 (p < 0.05). CONCLUSION: The present study demonstrated a weak correlation between the hip joint medial rotation ROM and the weight distribution of both feet. Such result suggests that careful evaluation by separating each element is needed in treating patients with low back pain. Future research should take into account asymmetric alignment and abnormal movement in different joints of the body as well as asymmetry in the bilateral hip joint rotation and the unilateral weight supporting posture.

The objective of this study was to propose a rehabilitation protocol for total hip replacement in Korean medicine and to report its effectiveness. Three patients who had undergone total hip replacement were treated using the rehabilitation protocol in Korean medicine. We evaluated the outcome evaluating physical examination findings of the hip joint, numeric rating scale, pain disability index, Harris hip score, and walking state. After the treatment, we observed that hip movement and muscular strength improved. Moreover numeric rating scale, pain disability index, Harris hip score, and walking state of patients improved. A rehabilitation in Korean medicine can be effectively used for total hip replacement patients. The limitation of this study was the insufficient number of cases. Further studies are needed to design a rehabilitation protocol in Korean medicine.

현재 인터넷에서 사용되고 있는 IP주소는 호스트 위치정보와 신원정보를 동시에 나타냄으로써 이동성 및 멀티호밍을 원활하게 지원하지 못하는 근본적인 문제를 지니고 있다. 이러한 문제를 해결하고자 호스트위치정보와 신원정보 분리를 주장하는 HIP(Host Identity Protocol)이 제안되었다. 그러나 IETF hip WG에서 HIP 적용을 위해 제시한 DNS(Domain Name System)가 기존의 DNS 기능의 일부 확장 아이디어만을 제시하여 그 구체성이 결여되어 있다. 본 논문에서는 HIP이 원활하게 지원될 수 있도록 동적 DNS를 구체적으로 설계하였다. 즉 기존의 DNS에 호스트 신원(Host Identity Namespace) 및 랑데뷰 서버 네임스페이스(Rendezvous Server Namespace)를 추가하고 새로운 자원 레코드(PR, Resource Records)들을 정의하였다. 이를 통해서 아이디어 차원의 HIP용 동적 DNS를 보다 구체화 하였다.

Purpose: Hip rotation testing is important in the evaluation of chronic back pain. The purpose of this study was to investigate hip and lumbopelvic movement during hip medial rotation (HMR) in individuals with chronic lower back pain (CLBP). Methods: This study targeted 112 subjects in total: 28 healthy males and 28 healthy females, and 27 males with CLBP and 29 females with CLBP. Motion-capture device was used to measure the hip medial rotation angle (HMRA), lumbopelvic rotation angle (LPRA), and the rotation angle of the hip when lumbopelvic rotation starts during hip medial rotation. Results: When evaluating the healthy males and females using the hip medial rotation test (HMRT), healthy males showed a smaller HMRA than did healthy females (p<0.05). When evaluating the healthy males and the males with CLBP using the HMRT, males with CLBP showed a smaller HMRA and more lumbopelvic movements than did healthy males (p<0.05) in addition, their lumbopelvic movements occurred earlier during HMR (p<0.05). Finally, when evaluating the males and the females with CLBP using the HMRT, males with CLBP showed a smaller HMRA and more lumbopelvic movements (p<0.05), and their lumbopelvic movements occurred earlier during HMR (p<0.05). Conclusion: The HMRT is an important test for the evaluation of males, and especially males with CLBP, as they often experience an increased LPRA and decreased HMRA, with lumbopelvic movement occurring earlier during HMR when compared to other groups.

Purpose: Hip microinstability is defined as hip pain with a snapping and/or blocking sensation accompanied by fine anatomical anomalies. Arthroscopic capsular plication has been proposed as a treatment modality for patients without major anatomic anomalies and after failure of properly administered conservative treatment. The purpose of this study was to determine the efficacy of this procedure and to evaluate potential predictors of poor outcome. Materials and Methods: A review of 26 capsular plications in 25 patients was conducted. The mean postoperative follow-up period for the remaining patients was 29 months. Analysis of data included demographic, radiological, and interventional data. Calculation of pre- and postoperative WOMAC (Western Ontario and McMaster Universities Osteoarthritis) index was performed. Pre- and postoperative sports activities and satisfaction were also documented. A P<0.05 was considered significant. Results: No major complications were identified in this series. The mean pre- and postoperative WOMAC scores were 62.6 and 24.2, respectively. The WOMAC index showed statistically significant postoperative improvement (P=0.0009). The mean satisfaction rate was 7.7/10. Four patients with persistent pain underwent a periacetabular osteotomy. A lateral center edge angle ≤21° was detected in all hips at presentation. We were not able to demonstrate any difference in postoperative evolution with regard to the presence of hip dysplasia (P>0.05), probably because the sample size was too small. Conclusion: Capsular plication can result in significant clinical and functional improvement in carefully selected cases of hip microinstability.

To date, family medicine and internal medicine fields have been responsible for defining, researching, and development of treatments for sarcopenia, focusing mainly on diabetes and metabolic diseases. Therefore, application of current guidelines for diagnosis of sarcopenia which differ according to continent to patients with hip fractures in the orthopedic field is difficult. The purpose of this review was to understand the recent consensus on the definition and diagnosis of sarcopenia and to highlight the importance of research and future research opportunities on the management of sarcopenia in patients with hip fractures by orthopedic surgeons. The global prevalence of sarcopenia in patients with hip fractures is statistically significant. Despite establishment of various therapeutic and diagnostic criteria for osteoporosis in the clinical field, there are no clear, useful diagnostic criteria for sarcopenia in the clinical field. In particular, few studies on the evaluation and treatment of sarcopenia in patients with hip fractures have been reported. In addition, the quality of life of postoperative patients with hip fractures could be significantly improved by development of precise assessment for muscle regeneration and rehabilitation in the operating room.

Background: Several studies have discussed diverse exercise methods considered to be useful for the selective contraction of the vastus medialis oblique (VMO) muscle for the treatment of patellofemoral pain syndrome. Some studies have reported that exercise methods, including hip adduction, in closed kinetic chain exercises are more effective in terms of the muscle activation of the VMO and the timing of the muscle's initial contraction. We focused on isometric contraction during a closed kinetic chain exercise with hip adduction. Objects: The purpose of this study was to examine muscle activation in the VMO and the vastus lateralis (VL) and the onset time difference between their initial contractions via closed kinetic chain isometric quadriceps femoris exercises including hip adduction. Methods: In total, 36 healthy subjects adopted two hip positions during isometric contraction of the quadriceps femoris in a closed kinetic chain exercise (hip neutral and hip adduction position). Statistical analyses were conducted using a paired t-test (${\alpha}=.05$). Results: Isometric contraction of the quadriceps femoris in a closed kinetic chain exercise caused a greater increase in VMO muscle activity in the hip adduction position [$52.68{\pm}22.21$ percentage of maximal voluntary isometric contraction (%MVIC)]than the hip neutral position ($43.43{\pm}19.85%MVIC$). The onset time difference (VL-VMO) decreased more in the hip adduction position ($-82.14{\pm}34.2ms$) than the hip neutral position ($73.94{\pm}2.94ms$). Conclusion: We recommend this exercise as a clinically useful therapeutic method for patients with patellofemoral pain syndrome due to weakening of the VMO muscle and lateral inclination of the patella.
