�� Purpose: The aim of this study was to develop and validate identification criteria for the cases of osteoporotic hip fracture using the National Health Insurance Database, and we calculated the incidence rate of osteoporotic hip fracture in the Korean population using these criteria. Materials and Methods: The criteria to identify osteoporotic hip fracture using a diagnosis code, a procedure code, the type and number of medical service usages and the patients' ages were developed via discussions among experts. These criteria were validated by using a hip fracture cohort in which all the genuine osteoporotic hip fracture patients in the Jeju area were identified by reviewing the registered medical records and radiographs. By applying the identification criteria to the National Health Insurance Database that was accumulated until June 2009, we calculated the incidence rate of osteoporotic hip fracture in patients between 50 and 100 years of age in 2008. Results: The identification criteria had a sensitivity of 93.1% and a positive predictive value of 77.4%. A total of 20,432 osteoporotic hip fracture cases were identified in 2008, and the incidence rate was 15.7 cases per 10,000 persons. The osteoporotic hip fracture incidence rate for females was 20.7 (per 10,000persons), and this was 2.1 times higher than that for the males (9.8case per 10,000persons), and the rates were increased with age. Conclusion: The incidence of osteoporotic hip fracture that occurred on a nationwide scale can be more precisely estimated by using the National Health Insurance Database with its comprehensive information on the overall details of treatment as well as the diagnosis codes, and so the incidence of osteoporotic hip fracture can be reliably calculated for each year. The results from this research could be used as evidence in a hip fracture management plan for establishing Korean Health policy.

The incidence of pyomyositis, initially considered to be a disease of the tropic, has been growing worldwidely, mainly affecting children and young healthy adults even in temperate climates. It predominantly affects quadriceps, iliopsoas, and gluteal muscles of the lower limb in sequence. The involvement of obturator muscles has rarely been reported and difficult to diagnosis. We report a rare case of obturator internus pyomyositis in a 29-yearold male of teraplegic condition with highlighting its importance of awareness and the relevant radiological investigations in the form of CT enhancement.

Results: The mean inclination angle of the acetabular cup was 39.3 for the ceramic-on-ceramic THRA and 44.4 for the ceramic-on-polyethylene THRA. There were no significant differences between the 40 and 45 (P=0.059, P=0.071). Conclusion: The pelvic tilt can be evaluated by checking the lateral decubitus X-ray with a goniometer and pointer. Insertion of an acetabular cup at the adjusted angle could be a credible method for reducing the variability of cup inclination.

Purpose: This study attempted to evaluate the pattern of change of the pain after total hip arthroplasty (THA) and to confirm the effect of periarticular multimodal drug injection (PMDI) on controlling the early postoperative pain. Materials and Methods: Of the total patients who underwent primary THA at our hospital because of osteonecrosis of the femoral head from March to October 2008, 60 patients were enrolled in this study. The subjects were divided into three groups. Groups 1 & 2 received periarticular injection. Group 1 included the patients who were injected with a combination of opioid, long-acting local anesthetics, a non-steroidal anti-inflammatory drug and epinephrine. Group 2 received a combination of morphine and ropivacaine and group 3 was not injected with any analgesics. The visual analogue scale (VAS) at 4 hours, 8 hours, 12 hours, 24 hours, 2 days, 3 days, 5 days, 14 days and 1 month after surgery, the frequency that patients pushed the self-controlled pain medication machine for 2 days after surgery and the amount of clonac that was injected according to the needs of the patients were used as objective measures. Results: The VAS score at postoperative 4 hours to 3 days among the groups showed a significant difference (P 0.05). The frequency of pushing the self-controlled pain medication machine among the groups and the amount of clonac according to the needs of the patients among the groups showed that there were significant decreases at the operation day, the postoperative 1, 2 day and the 3 days (P<0.05). Conclusion: PMDI has a significant effect on controlling the early postoperative pain after THA.
目的:本研究旨在评价全髋关节置换术(THA)术后疼痛的变化规律，并证实关节周多模态药物注射(PMDI)对术后早期疼痛的控制作用。材料与方法:2008年3月至10月在我院因股骨头坏死行原发性THA的患者中，有60例纳入本研究。受试者被分成三组。1、2组均予关节周注射。第一组包括联合注射阿片类药物、长效局部麻醉剂、非甾体抗炎药和肾上腺素的患者。2组给予吗啡和罗哌卡因联合用药，3组不注射任何镇痛药。以术后4小时、8小时、12小时、24小时、2天、3天、5天、14天、1个月的视觉模拟评分(VAS)，术后2天内患者推自控止痛药机的次数，以及根据患者需要注射的泻药量作为客观衡量指标。结果:两组患者术后4 h ~ 3 d VAS评分差异有统计学意义(P < 0.05)。各组间按患者需要推用自控镇痛机的次数及清肠液用量在手术当日、术后第1、2、3天均有显著降低(P<0.05)。结论:PMDI对THA术后早期疼痛有明显的控制作用。

Purpose: We wanted to assess the benefits and safety of periarticular soft tissue injection of bupivacaine and morphine in total hip arthroplasty by conducting a prospective randomized trial. Materials and Methods: Between February 2008 and January 2010, a prospective, randomized study was performed on fifty patients with an American Society of Anesthesiology stage of I or II. All the patients were administered COX-2 inhibitor and we used PCEA (Patient Controlled Epidural Analgesia) for 24 hours postoperatively. All the patients underwent their operation under general anesthesia. Fifty randomly selected patients were divided into two groups. After reduction of the hip joint, 50 ml of normal saline was intraoperatively injected into 25 patients (Group A) and 50 ml of locally injected analgesia that included 0.5 ml 5 mg of morphine HCL, 40 ml of 0.5% 50 mg chirocaine (Levo-bupivacaine) and 9.5 ml of normal saline was injected into the capsule and the soft tissue and muscle around the hip joint in 25 patients (Group B). The analgesic efficacy was evaluated by the visual analogue scale (VAS) at 6 and 12 hours postoperatively with the patients in a resting state and at 24, 48 and 72 hours postoperatively with the patients in a resting state and during a passive exercise (30 ) state. The consumption of PCEA and additional analgesic drugs was also evaluated postoperatively. Results: Significant differences were found between the 2 groups (P 0.05). Conclusion: Intraoperative periarticular soft tissue injection of bupivacaine and morphine can significantly reduce pain and it can reduce the requirement for patient-controlled analgesia, with no apparent risks, following total hip arthroplasty.

Purpose: This study examined the treatment of patients with posterior hip dislocation and femoral head fracture, according to the Pipkin classification, and we analyzed their clinical and radiological results. Materials and Methods: The subjects consisted of 45 patients who were treated for posterior hip dislocation and femoral head fracture. The subjects had an average age of 39, and 38 were men and 7 were women. The average follow-up period was 33 months. The cause of injury was traffic accident in 41 cases and falling for the other four cases. According to the classification, there were 26 Type I cases, 5 Type II cases, 1 Type III case and 13 Type IV cases. The treatment methods were selected according to the patients’ condition and the form of fracture. The Ebstein criteria and the Merle d’Aubigne and Postel score were used to determine whether there was a combined injury and to examine the clinical and radiological results. Results: All the cases classified as Type I, II and III showed good or excellent clinical results. A primary osteosynthesis was performed on the Type III cases according to the patient’s age and condition, with particularly good results. An anatomical reduction in the early stages affected the clinical results of the Type IV cases. The observed complications were posttraumatic osteoarthritis (38.4%) and avascular necrosis (15.3%). Conclusion: The prognosis was determined by the injury’s initial severity, the time for reduction and the anatomical reduction and firm fixation of the femur and the fracture fragment of the acetabulum.

Conventional gamma sterilization could induce substantial oxidative degradation during subsequent storage of the PE component in air and during their use in vivo. This oxidative degradation may induce high wear rates, delamination and/or gross fracture of the affected PE component. An improved understanding of the effects of cross-linking and oxidation on ultra high molecular weight polyethylene (UHMWPE) has lead to the common use of oxygen-protected packing during radiation sterilization and shelf storage. More recently, methods to deliberately highly cross link UHMWPE while reducing the material’s potential to oxidize have been develop in the form of highly cross linked UHMWPE. We reviewed the manufacturing, sterilization, cross linking methods and clinical results of the new polyethylene.

We reviewed the manufacturing, sterilization, cross linking methods and clinical results of the new polyethylene.","PeriodicalId":410202,"journal":{"name":"The Journal of the Korean Hip Society","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132082130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jehovah's Witnesses are widely known for their prohibition for accepting blood transfusion. Because of the firm refusal to receive transfused blood and blood components by Jehovah's Witnesses, the management of Jehovah's Witness patients with severe bleeding is often complicated by medical, ethical and legal concerns. We report here on two cases of successful treatment of Jehovah's Witnesses who underwent total hip replacement for secondary osteoarthritis and Chiari osteotomy for acetabular dysplasia.

Revision after primary total hip arthroplasty is usually much more difficult than the first time, and the results are typically not as satisfactory as that after most primary total hip arthroplasties. Revision requires more operative time and more blood loss, and there are higher incidences of infection, thromboembolism, dislocation, nerve palsy and perforation/fracture of the femur. The complexities of revision surgery underscore the importance of precise technique when performing primary arthroplasties. Thoughtful and thorough preoperative planning will certainly provides the patient with the best opportunity for long-term success.
