3Y-TZP (3 mol% yttria-stabilized tetragonal zirconia polycrystals, 3Y-TZP) ceramics are emerging as dental implant materials due to their superior optical and mechanical properties as well as excellent biophysical properties, in spite of low bioactivity. In this study, we investigated to sintered properties and microstructural defects of dental zirconia implants fabricated by ceramic injection molding and post-HIP (Hot isostatic pressing) processing and analyzed the processing parameters related with the obtainment of its high sinterd density. Sintered and microstructural parameters, i.e, apparent density, grain size and phase composition of zirconia implants fabricated by injection molding were dependent on the fixtute size and implant type. Maximum sintered density of 99.2% and minimum grain size of 0.3-0.4 ㎛ were obtained from large-scaled 2-body sample. In 1-body ceramic implant, high sintered density of 99.5% was obtained, but it had a little monoclinic phase and wide grain size distribution.

Purpose: Clinical characteristics and medical cost were analyzed according to the surgical procedures for intertrochanteric fracture in aged patients to assess the appropriateness of treatment expense and to find possibility of reducing the medical cost. Method: Variable for the statistical analysis were; the clinical characteristics, medical cost according to the surgical procedures, the treatment success rate, the total medical expense, and the average expense per case. SAS Package Version 8.02. was used to analyze the relevant data. Results: Operative procedures differ significantly according to the gender and by the location of institution. Only significant clinical variables according to the operative procedure were duration of general anesthesia and amount of blood transfusion. Average cost per treatment was the highest in the bipolar hemiarthroplasty followed by the gamma nail and hip compressing screw. Average cost for bipolar hemiarthroplasty was significantly higher than other surgical procedures. Conclusions: The difference in hospital costs for treatment of intertrochanteric fracture originates from the utilized surgical procedures, mostly by the materials used. The method of surgical treatment should be carefully determined by the purpose of the surgery, in order to improve the quality of medical care and also to reduce the hospital cost.

YBa2Cu3O7-x oxide superconductors were fabricated by sintering and hotisostatic pressing (HIP), and their microstructures and properties were compared with each other. Thougha part of the second phase was observed along grain boundaries, their structures were consisted of single (123) phase and they had many porosities. But, porosities were remakably reduced by Hiping and the densification was brought about. The structure of (123) compound also showed a number of twins, which are typical of high Tc superconductors. The on-set temperature of YBa2Cu3O7-x compound sintered at 96$0^{\circ}C$ in oxygen and hipped at 88$0^{\circ}C$ was highest, but that shwoed 0 resistance at 87$^{\circ}$K, which is a little lower than the compound sintered at 96$0^{\circ}C$. HIP treatment also increased the critical current density of as-sintered compound. However, its value was low, which may be ascribed to the many pores of starting-sintered compact and partially to the second phase along grain boundaries.

This case study reports the clinical response to Korean Medicine (KM) treatments including capsaicin-containing (CP) pharmacopuncture in three patients with acute low back and hip pain. Three patients were diagnosed with acute lumbar sprain, and were treated with CP pharmacopuncture, and other KM treatments including acupuncture, cupping, and herbal medicine. Numeric Rating Scale (NRS), Oswestry Disablility Index (ODI), and Clinical Evaluation Grade (CEG) were used to evaluate symptom changes. After one or two treatments, acute pain with limited range of motion in the low back and thigh region improved with a decrease in NRS, ODI, and CEG. These results suggest that further studies on KM treatments including CP pharmacopuncture for acute low back and hip pain are warranted.

Objectives : To evaluate the current status of East-West combination treatment in joint disorders. Methods : The medical records of patients who visited the Joints & Rheumatism Center at the Kyung Hee East-West Neo Medical Center from April 2006 to June 2009 were evaluated. The general characteristics of patients who underwent combination treatment, trend in number of cross-system referrals, and disorders and involved body regions of patients referred to the Eastern medical hospital from the Western medical hospital were initially assessed. 6 major disorders were found from the initial scanning. The trend in number of cross-hospital referrals, number of visits to the Eastern medical hospital, current status of combination treatment, treatment modality, and reason for cross-system referral was evaluated. Results : 1. 1510 patients were referred from the Eastern medical hospital to the Western medical hospital, and 1065 patients were referred from the Western medical hospital to the Eastern medical hospital. First visit patients reached a peak at the second quarter of 2007 and fourth quarter of 2006 respectively, and have steadily decreased from then on. Referrals of female patients were twice as common as male patient referrals. Patients in their sixth or seventh decade of life were most commonly referred, and more outpatients were referred compared to inpatients. 2. Patients with knee joint disorders were most commonly referred from the Western medical hospital to the Eastern medical hospital, followed by hip, shoulder, ankle, wrist, and elbow joint disorders. The most common disorders for each of the above regions in referred patients were knee osteoarthritis, avascular necrosis of the hip, adhesive capsulitis, and ankle strain and sprain. The generalized disorders rheumatoid arthritis and ankylosing spondylitis followed. 3. Patients referred to the Eastern hospital received approximately 3 to 10 Eastern medical treatment sessions. 45 percent remained on constant combination treatment, and 98 percent of referred patients received acupuncture treatment. Conclusions : In regard to the number of patients and duration of combination treatment, combination treatment was successfully performed for knee osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis, while it was not so for avascular necrosis of the hip, adhesive capsulitis, and ankle strain and sprain. Further research on this subject is required.

The aim of this review is to conduct an analysis of existing literature on outcomes of application of various methods of joint decompression in management of septic arthritis of the hip in children. A search of literature in PubMed, Embase, and Google Scholar was conducted for identification of studies reporting on the outcomes of intervention for septic arthritis of the hip in children. Of the 17 articles selected, four were comparative studies; two of these were randomized controlled trials while the rest were single arm studies. Statistical difference was observed between the proportion of excellent clinical and radiological outcomes in arthrotomy (90%, 95% confidence interval [CI] 81-98%; 89%, 95% CI 80-98%), arthroscopy (95%, 95% CI 91-100%; 95%, 95% CI 90-99%), and arthrocentesis (98%, 95% CI 97-100%; 99%, 95% CI 97-100%), respectively. The highest overall rate of additional unplanned procedures was observed in the arthrocentesis group (24/207, 11.6%). Patients who underwent arthrocentesis had a statistically greater chance of excellent clinical and radiological outcomes, although the highest level of need for additional unplanned surgical intervention was observed in the arthrocentesis group, followed by the arthroscopy group and the arthrotomy group. Future conduct of a prospective multi-centric study focusing on the developed and developing world, along with acquisition of data. such as delay of treatment and severity of disease will enable assessment of the efficacy of one technique over the other by surgeons worldwide.
