Purpose: The purpose of this study is to examine how well patients who had hip arthroplasty comply with medical regimens given to them after the operation. Method: The subjects of the study were patients who had arthroplasty at P Hospital between April 1, 2001 and August 30, 2002. 20 patients of the subjects experienced complications after the operation and the other 20 did not. Data from a survey using the qustionnaire were statistically analyzed in terms of real number, percentage point, mean and standard deviation by using $X^2$-test, t-test and ANOVA. Result: 1) the surveyed patients were significantly different in the compliance of medical regimen among them according to their education background as one of the subjects general characteristics. 2) It was found that the group of complication was higher in the compliance of medical regimen than that of non-complication. The two groups showed statistically significant difference with each other in the degree of compliance with therapeutic instructions than the experimental group in terms of the maintenance of abduction after the operation, training instructions on step-by-step basis, urination cotrol on bed, accurate use of crutch, compliance with medication, balance among medical treatment, training, leisure, rest and nutrition, instructions by physicians, nurses and physical therapists, use of low armchairs and toilet bowels and no bending of the body forward, and use of a non-operated leg in case of go upstairs or downstairs. Conclusion: It seems necessary to develop systematic and sessional education programs for improving the compliance of medical regimen, ultimately reducing complications following hip arthroplasty.

Purpose: This study was a qualitative research using focus group interviews to collect data on the health care providers' perceptions of physical function in older adults with arthroplasty from hip fracture. Methods: A total of 12 subjects participated in this study. In order to conduct focus group interviews, structured manuscript, field notes, visual recording, and debriefing notes were referred and thematic analysis was used in analysis phase. Results: The six themes were raised: 'burdensome client', 'health care providers' perception of functional decline in older adults after surgery', 'health care providers' perception of caregiver', 'medical environment perceived as affecting physical function', 'crucial components perceived as encouraging functional restoration', and 'difficulty of pain management' with 18 subthemes. Conclusion: Healthcare providers perceived functional decline of elderly after arthroplasty and identified points facilitating or disturbing physical function Moreover, various perspectives on pain management related to physical function were represented.

고관절과 그 주위의 질환들의 진단적 검사는 그 동안 주로 단순 방사선 검사와 CT, MRI등이 이용되어 왔다. 그러나 고관절 주위의 건과 점액낭 등에 의한 병변에는 초음파 검사가 진단에 유용할 수 있으며 또한 추적 검사에도 활용될 수 있는 장점이 있다. 그 외에도 인공고관절 치환 수술 후에도 추적 검사상 활용도가 있어 그 사용이 넓어질 여지가 있다. 하지만 시술자의 숙련도에 따라 결과가 달라질 수 있다. 본 논문에서는 고관절 주위의 정상적인 구조물들의 초음파 영상과 병적 소견들을 소개하고 그 개략적인 것들을 설명하였다.

The objectives of the present study is to examine the validity of Charlson Comorbidity Index(CCI) based on medical record data; to utilize the index to determine outcome indexes such as mortality, length of stay and cost for the domestic patients whose have received total hip arthroplasty. Based on medical record date, 1-year Mortality was analyzed to be 0.664 of C statistic. The $R^2$ for the predictability for length of stay and the cost was about 0.0181, 0.1842. Fee of national health insurance and total cost including the cost not covered by insurance, also had statistically significance above 3 points of Charlson point score(p=0.0290, 0.0472; $p.{\le}0.05$). The 1-year mortality index, length of stay and cost of the total hip arthroplasty patients which was obtained utilizing CCI have a limitative prediction power and therefore should be carefully analyzed for use.

무혈성 골괴사는 골조직 및 골수 조직의 허혈성 상태로 인한 괴사로 정의될 수 있으며, 외상성 및 비외상성으로 구분할 수 있다. 무혈성 골괴사는 대퇴골 골두, 상완골 골두와 같이 장골의 골단 부위에서 주로 발생한다. 기존의 무혈성 골괴사는 대부분 대퇴골 골두에 한정된 증례에 대한 보고 및 연구가 이루어져 왔다. 근위 대퇴골의 무혈성 괴사의 존재는 인공 고관절 전치환술 이후 생물학적 고정 실패의 원인이 된다. 본 저자들은 대퇴골 골두로부터 대퇴골 경부, 간단부 간부 및 원위부에 이르는 골수강내 부위의 대퇴골 전 영역의 무혈성 골괴사가 관찰된 56세 남자 환자에서 인공 고관절 전치환술을 시행하고 2년 추시 결과를 문헌 고찰과 함께 보고하고자 한다.

Background: The advantages of robotic therapy have recently been attempted several times in the rehabilitation of total hip arthroplasty (THA) patients. Therefore, this study also aims to report a case of how robot therapy affects the function of THA patients due to developmental dysplasia of the hip (DDH). Design: Case Study. Method: This study used the A-B-A' design. Period A is before robotic therapy, period B is robotic therapy, and period A' is after robotic therapy. The subjects performed physical therapy and occupational therapy for five days each during the baseline period A and A'. In intervention period B, robotic therapy was performed for five days along with the baseline intervention. This study was conducted for a total of fifteen days. The subjects' sit to stand (STS), timed up and go (TUG), and 10 metre walk (10MW) were evaluated. Result:: STS and TUG were significantly improved in periods B and A' compared to period A (p<0.05), and STS was significantly improved in period A' compared to period B (p<0.05). 10MW showed no significant improvement in periods B and A' compared to period A. Conclusions: This study confirmed that robot therapy was an effective intervention in improving the function of women in their 30s who underwent THA due to DDH. In the future, a study comparing the control group should be performed.

Background: Hypoalbuminemia (serum albumin < 3.5 g/dL) is associated with increased morbidity and mortality in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). However, costs associated with hypoalbuminemia remain unknown. This study investigated the effect of serum albumin on direct treatment costs, length of stay (LOS), and readmissions for primary and revision THA and TKA patients. Methods: All adult patients at a single institution undergoing primary or revision THA or TKA between January 2014 and December 2016 were retrospectively reviewed. Patients were stratified by preoperative serum albumin level. The primary outcome was total direct costs at index hospitalization. Secondary outcomes included LOS and readmission within 30 days. Multivariable regressions were utilized to adjust for demographics and comorbidities. Results: Of 3,785 patients, 114 (3.0%) had hypoalbuminemia. After adjustment, hypoalbuminemia was associated with a 16.2% increase in costs (${\beta}=0.162$; 95% confidence interval [CI], 0.112 to 0.213; p < 0.001), representing an average cost increase of $3,383 (95% CI, $2,281 to $4,485) relative to costs for serum albumin > 4.5 g/dL. The increased total costs were significantly higher in revision ($4,322, p = 0.034) than in primary ($3,446, p < 0.001) procedures. In adjusted regression, each 1.0 g/dL increase in serum albumin yielded a 6.6% reduction in costs (${\beta}=-0.066$; 95% CI, -0.090 to -0.042]; p < 0.001), for average savings of $1,282 (95% CI, $759 to $1,806) per unit albumin. Adjusted regressions demonstrated that a 1-point increase in serum albumin reduced readmissions by 53% (odds ratio, 0.47; 95% CI, 0.31-0.73; p = 0.001) and LOS by 0.6 days (${\beta}=-0.60$; 95% CI, -0.76 to -0.44; p < 0.001). Conclusions: Hypoalbuminemia is associated with increased total direct costs, LOS, and readmissions following primary and revision THA and TKA. Future efforts to predict and address total costs should take into consideration the patient's preoperative serum albumin levels.

To improve surgical result of total hip arthroplasty (THA), there has been some approaches using a robotic milling system, which can make a precise cavity in the femur. Usually, to carve a femur, the surgical robot is controlled by a pre-programmed tool-path regardless of a surgeon's experience and Judgment. This paper presents a control method of a surgical robot for THA, which can be used as an advanced surgical tool. With a master/slave combined surgical robot, surgeon can directly control the motion and velocity of a surgical robot. The master/slave-combined robot is controlled to display a specific admittance for a surgeon's force to the surgical robot velocity. To prevent the over-carving of a femur, virtual hard wall is displayed on the surgical boundary. To evaluate the proposed control method of the master/slave-combined surgical robot, 2-DOF master/slave-combined manipulator is used in experiment.
