5.Robotic Surgery in the Orthopedic Field.
The Journal of the Korean Orthopaedic Association 2018;53(6):459-465
Of the many factors that affect the clinical outcomes of orthopedic surgery, the surgical procedure is the most important. Robotics have been developed to perform the surgical procedures more accurately and consistently. Robotic surgical procedures in the orthopedic field were developed 20 years ago. Some designs of surgical robots have disappeared due to practical problems and complications, and an another design of surgical robots is emerging. To date, the use of robot surgery in arthroplasty is still controversial in terms of the clinical outcomes, practicality, and cost-effectiveness, even though it has been reported to be effective in the alignment and positioning of components in the field of artificial joints. Early robotic surgery was based mainly on active robot surgery according to the scheduled operation without the intervention of the operator. Recently the semi-active system of robotic surgery has been introduced. In a semi-active system, the robot constrains the surgeon to a haptic boundary defined by the computer based on the 3-dimensional imaging preoperative plan, and the operator can change the preoperative plan through real-time feedback during operation.

Twin pregnancies represent a high risk obstetric population with perinatal morbidity and mortality much greater than that of singleton pregnancies. A retrospective dinical evaluation was attempted to analyse 211 cases of twin pregnancies in Chunchon Sacred Heart Hospital of Hallym University from Jan. l. 1988 to Dec. 31. 1997. The results were as follows. 1) The incidence of twin pregnancy was 1 in 93.9 deliveries. 2) The age of mother ranged from 19 to 42 years and predominant age group was 26-30 which covers 43.1% of all. 3) Nullipara was 61.1% and multipara was 38.9%. 4) The predominant gestational age group at delivery was 36-37 weeks, 33.2%. 5) In presentation, both cephalic combination was 46.4%, cephalic-breech was 26.1%. 6) The birth weight was less than 2500gm in 64.9% of the 1st babies and 70.6% of the 2nd babies, respectively. 7) The rate of cesarean section was 89.0%. The indications of cesarean section were malpresention (48.9%), elective cesarean section(38.8%), and toxemia(9.0%). 8) In 23 cases of vaginal delivery, the average duration of labor was 7.0 hours and 43.5% of 2nd baby was delivered within 5 min after 1st baby delivery, 9) The most frequent maternal complications during pregnancy were anemia(36.0%), preterm labor(34.6%) and preeclamsia(17.5%). 10) The perinatal mortality rate of the first and second twins was 10.4% and 12.3%, respectively. The main causes of perinatal death were prematurity(52.1%) and stillborn(22.9%). 11) Both female was 43.6%, both male was 39.3%, and opposite sex was 17.1% in infant.

STATEMENT OF PROBLEM: Macroscopic and especially microscopic properties of implant surfaces play a major role in the osseous healing of dental implants. Dental implants with modified surfaces have shown stronger osseointegration than implants which are only turned (machined). Advanced surface modification techniques such as anodic oxidation and Ca-P application have been developed to achieve faster and stronger bonding between the host bone and the implant. PURPOSE: The purpose of this study was to investigate the effect of surface treatment of titanium dental implant on implant stability after insertion using the rabbit tibia model. MATERIAL AND METHODS: Three test groups were prepared: sandblasted, large-grit and acid-etched (SLA) implants, anodic oxidized implants, and anodized implants with Ca-P immersion. The turned implants served as control. Twenty rabbits received 80 implants in the tibia. Resonance frequencies were measured at the time of implant insertion, 2 weeks and 4 weeks of healing. Removal torque values (RTV) were measured 2 and 4 weeks after insertion. RESULTS: The implant stability quotient (ISQ) values of implants for resonance frequency analysis (RFA) increased significantly (P < .05) during 2 weeks of healing period although there were no significant differences among the test and control groups (P > .05). The test and control implants also showed significantly higher ISQ values during 4 weeks of healing period (P < .05). No significant differences, however, were found among all the groups. All the groups showed no significant differences in ISQ values between 2 and 4 weeks after implant insertion (P > .05). The SLA, anodized and Ca-P immersed implants showed higher RTVs at 2 and 4 weeks of healing than the machined one (P < .05). However, there was no significant difference among the experimental groups. CONCLUSION: The surface-modified implants appear to provide superior implant stability to the turned one. Under the limitation of this study, however, we suggest that neither anodic oxidation nor Ca-P immersion techniques have any advantage over the conventional SLA technique with respect to implant stability.
