Objectives The objective of this study is to assess the effectiveness of electroacupuncture for patients with hip arthroplasty. Methods According to participants, intervention, comparison, outcome, study design, we searched for clinical studies that conducted electroacupuncture for patients with hip arthroplasty. Results Finally 11 randomized controlled trials were chosen for systemic review and meta-analysis. The frequently used evaluation tools were Incidence of postoperative cognitive dysfunction (POCD), heart rate, blood pressure. Almost studies showed electroacupuncture has effects for patients with hip arthroplasty. Through meta analysis, Electoacupuncture showed statistically significant effect of reducing the anesthetic dosage and incidence of postoperative psychonosema and adverse reactions in intra-operation period, reducing the incidence of POCD in peri-operation period, incidence of deep venous thrombosis in post-operation period. Conclusion 11 studies reported that electroacupuncture has significant effects on hip arthroplasty. But, many studies were assessed in a probable high risk of bias. And all studies published in one overseas country. So, it requires attention to comprehend this study. To make up for this limitaion, more well designed clinical research are needed.

Purpose: Total femoral replacement (TFR) is an extreme form of limb salvage. Considering the rarity of this procedure, reports have focused on the complications and a proper indication is unclear. This study analyzed 36 patients with TFR who were asked the following: 1) prognostic factors related to survival in patients who underwent TFR with a tumoral cause; 2) overall implant and limb survival; 3) complications, functional outcome, and limb status for patients surviving for more than 3 years. Materials and Methods: According to the causes for TFR, 36 patients were categorized into three groups: extensive primary tumoral involvement (group 1, 15 cases), tumoral contamination by an inadvertent procedure or local recurrence (group 2, 16 cases), and salvage of a failed reconstruction (group 3, 5 cases). The factors that may affect the survival of patients included age, sex, cause of TFR, and tumor volume change after chemotherapy. Results: The overall five-year survival of the 36 patients was 31.5%±16.2%. The five-year survival of 31 patients with tumoral causes was 21.1%±15.6%. The five-year survival of 50.0%±31.0% in patients with a decreased tumor volume after chemotherapy was higher than that of increased tumor volume (p=0.02). The five-year survival of 12 cases with a wide margin was 41.7%±27.9%, whereas that of the marginal margin was 0.0%±0.0% (p=0.03). The ten-year overall implant survival of 36 patients was 85.9%±14.1%. The five-year revision-free survival was 16.6%±18.2%. At the final follow-up, 12 maintained tumor prosthesis, three underwent amputation (rotationplasty, 2; above knee amputation, 1), and the remaining one had knee fusion. Among 16 patients with a follow-up of more than three years, 14 patients underwent surgical intervention and two patients had conservative management. Complications included infection in 10 cases, local recurrences in two cases, and one case each of hip dislocation, bushing fracture, and femoral artery occlusion. Conclusion: Patients showing an increased tumor volume after chemotherapy and having an inadequate surgical margin showed a high chance of early death. In the long-term follow-up, TFR showed a high infection rate and the functional outcome was unsatisfactory. Nevertheless, this procedure is an inevitable option of limb preservation in selected patients.

Objectives This study was conducted to assess the effect of chuna manual therapy after hip arthroplasty. Methods We searched across 9 electronic databases (PubMed, Cochrane Library, Wangfang data, China National Knowledge Infrastructure [CNKI], Oriental Medicine Advanced Searching Integrated System [OASIS], National Digital Science Library [NDSL], Korean Medical Database [KMBASE], Koreanstudies Information Service System [KISS], Research Information Sharing Service [RISS]) to find randomized controlled clinical trials for chuna manual therapy after hip arthroplasty. Results On inclusion criteria, 11 appropriate studies were included and analyzed. The deep vein thrombosis incidence of the chuna manual therapy group was statistically lower than the conventional treatment group (p=0.0002). Chuna manual therapy significantly improved the Harris hip score compared with conventional treatment (p<0.00001). Also, chuna manual therapy combined with herbal fumigation therapy significantly elevated the hip joint function score of Harris hip score compared with the conventional therapy group (p<0.00001). Conclusions The systematic review showed that chuna manual therapy had significant effects on hip arthroplasty. Nonetheless, considering the high risk of bias and geographic bias, further research with well-designed studies is required to support the effectiveness of chuna manual therapy.

The problems related with blood supply shortage and the stability of blood transfusion are on the rise, as it is expected that the blood doners will decrease but the blood use amount for aged population will increase, owing to low birth and aged population increase. The purpose of this study is to analyze the hospital characteristics which affect patients receiving and non-receiving blood transfusion for the knee and hip total replacement arthroplasty. Data were collected from Health Insurance Review and Assessment Service's 2011 sample data, and 5,370 inpatients were abstracted from them. Logistic regression analysis was performed, using SPSS 20. Independent variables used are hospital characteristics variables and patient characteristics variables. Hospital characteristics variables are hospital type, ownership, residence and the number of usable beds, and patient characteristics variables are gender, age, severity, type of anesthesia, main diagnosis, whether or not of anemia and insurance class. At the result of this study, it was found that hospital type, region, gender, age, severity, main diagnosis and whether or not of anemia were the factors that mostly affected the blood transfusion for knee arthroplasty. And hospital type, residence, gender, age, severity, type of anesthesia and whether of not of anemia were the factors that mostly affected the blood transfusion for hip arthroplasty. In addition to that, it is expected that this research which analyzed the present state of blood transfusion and its influence factors are cost effective, and would make a good use of preliminary data for good quality of medical service.

Background: As the patients who undergo heart transplantation have achieved better survival in recent years, growing number of recipients are at a risk for experiencing surgical complications in addition to rejection and infection. In this paper, we report on our experience with the surgical complications that occurred in heart transplant recipients. Material and Method: From April 1994 to September 2003, 37 heart transplantations were performed at our center by a single surgeon. The indications for transplantation were dilated cardiomyopathy, ischemic cardiomyopathy, valvular cardiomyopathy and familial hypertrophic cardiomyopathy. Result: Twenty postoperative complications required surgeries in 15 patients (41%). The types of operations required were; redo-sternotomy for bleeding (5), pericardiostomy for effusion (4), implantation of a permanent pacemaker (1), right lower lobe lobectomy for aspergilloma (1), removal of urinary stone (1), cholecystectomy for gall bladder stone (1), drainage of a perianal abscess (1), paranasal sinus drainage (1), total hip replacement (1), partial gingivectomy due to gingival hypertrophy (1), urethrostomy (1), herniated intervertebral disc operation (1) and total hysterectomy for myoma uteri (1). The locations of the complications were mediastinal in 10 (27%) cases and extramediastihalin 10 (27%) cases. Conclusion: The relatively high incidence of extrathoracic complications associated with heart transplantation emphasizes the importance of a multidisciplinary approach to the improve long-term survival when managing those complex patients.

Objectives: We assessed impact of performance reporting information about the readmission rate, length of stay and cost of hip hemiarthroplasty. Methods: The data are from a nationwide claims database, National Quality Improvement Project database, of Health Insurance Review & Assessment Service in Korea. From January 2006 to April 2008, we received information of length of stay, readmission within 30 days, cost of 22 851 hip hemiarthroplasty episodes. Each episodes has retained the diagnoses of comorbidities and demographics. We used time-series analysis to assess the shifting of patients selections, between high volume (over 16 operations in a year) and low volume institutions, after performance reporting (December 2007). The changes of quality (readmission, length of stay) and cost were evaluated by multilevel analysis with adjustment of patient's factors and institutional factors after performance reporting. Results: As compared with the before performance reporting, the proportion of patients who choose the high volume institution, increased 3.45% and the trends continued 4 months at marginal significance (p = 0.059). After performance reporting, national average readmission rate, length of stay were decreased by 0.49 OR (95% CI=0.25 - 0.95) and 10% (${\beta}$=-0.102, p<0.01) and cost was not changed (${\beta}$=-0.01, p=0.27). The high volume institutions were more decreased than low volume in length of stay. Conclusions: After performance reporting, readmission rate, length of stay were decreased and the patient selections were marginally shifted from low volume institutions to high volume institutions.

Objective: Currently, rivaroxaban is widely used clinically for thromboprophylaxis after surgery. However, there are concerns on effectiveness and safety of rivaroxaban for its proper use. We aimed to evaluate the effectiveness and safety of rivaroxaban in orthopaedic patients after total hip replacement surgery in a large medical centre after the preferred formulary was switched from enoxaparin to rivaroxaban. Methods: The study was conducted on the patients who underwent hip arthroplasty surgery at the department of Orthopaedic Surgery at Seoul St. Mary's Hospital, South Korea. Electronic medical records were retrospectively reviewed to identify patients treated with rivaroxaban following total hip replacement between February 2011 and March 2012. Evaluation criteria included indications for use, dose, initiation and duration of therapy, drug interactions, adverse reactions, and status of health care reimbursement. The patients who were on enoxaparin were also reviewed as a reference. Results: We identified 57 patients who received rivaroxaban and 50 who received enoxaparin. All patients were prescribed the drugs for Korean Food and Drug Administration-approved indications. No thromboembolic or bleeding events were observed in either group. However, only 5.3% of rivaroxaban- treated patients had an appropriate length of prophylaxis and only 3.5% began rivaroxaban treatment at the recommended time. Surprisingly, 47.4% of rivaroxaban-treated patients received rivaroxaban despite being ineligible for reimbursement benefits. Conclusion: Rivaroxaban was generally well tolerated clinically. However, the duration of treatment, the time of initiation and patient eligibility for reimbursement require improvements, emphasising the need for education which indicates the area of pharmacists' involvement.

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.

Purpose SPECT/CT scan to be performed attenuation correction on the basis of CT induce an overestimation of the site due to the beam hardening artifact by metal cover and reduce the images quality. Therefore, this study using a phantom that has been inserted artificial hip joint investigated that effect on the SPECT/CT image causing by metal artifact for varying the parameters of the Attenuation Map. Materials and Methods Siemens Symbia T16 SPECT/CT equipment was used. Artificial hip joint was inserted to SPECT/PET phantom, 17 mm sphere of Bright Streak area in CT image was filled with Tc-99m so that the radiation activity was 8 times compared to background. And then Hot and Background was measured in varying Wide Beam Coefficient on Attenuation Map and RBR (Region to Background Ratio) of Metal and Non-Metal was calculated and analyzed depending on the presence or absence of the hip joint. Results It tended to hot count of Non-Metal and Metal to increase as the value of the manual mode is increased, hot count ratio with the group of both manual mode 0.5 and 0.4 is the best match. Also, in automatic mode, the ratio of RBRNon-Metal and RBRMetal was 1.135, statistically significant difference was not observed in the manual mode 0.5 and 0.4. Conclusion In the automatic mode of Wide Beam Coefficient in attenuation correction map, it was found that it is over-correction by 13.52%, it was possible to minimize the over-correction by the artifact in 0.5 and 0.4 of manual mode. Further studies should be performed in order to apply to a patient with the help of this and it is considered possible to reduce the over-correction by the metal artifact of an artificial hip joint for Hip-Resurfacing Arthroplasty patients, and to improve the diagnostic performance.
