The applications of 3D printing technology in health care, particularly orthopedics, continue to broaden as the technology becomes more advanced, accessible, and affordable worldwide. 3D printed models of computed tomography (CT) and magnetic resonance image (MRI) scans can reproduce a replica of anatomical parts that enable surgeons to get a detailed understanding of the underlying anatomy that he/she experiences intraoperatively. The 3D printed anatomic models are particularly useful for preoperative planning, simulation of complex orthopedic procedures, development of patient-specific instruments, and implants that can be used intraoperatively. This paper reviews the role of 3D printing technology in orthopedic surgery, specifically focusing on the role it plays in assisting surgeons to have a better preoperative evaluation and surgical planning.
Study Design: A prospective randomized cohort study. Objective: The objective of this study was to investigate the effect of intraoperative vertebral anesthesia on osteoporotic vertebral compression fractures (OVCFs) when treated with percutaneous kyphoplasty (PKP). Summary of Background Data: Only a few studies have evaluated the intraoperative pain reducing strategies during PKP. Materials and Methods: A total of 64 patients with OVCFs were enrolled in the study. All of the patients were randomized into 2 groups: the traditional local anesthesia group (from the skin to the periosteum, group A) and the experimental group (from the skin to a vertebral body, group B). Visual Analogue Scale (VAS) score was used to evaluate the degree of pain at six time points, that is, VAS before surgery, VAS during balloon dilation, VAS during bone cement injection, VAS soon after surgery, and VAS 12 hours and 24 hours after surgery. In addition, we noted the patients’ willingness to undergo reoperation if necessary, and the variations in surgical complications between the 2 groups. Results: There was no significant difference in VAS score before surgery between the 2 groups (t=1.694, P=0.095). The VAS scores during balloon dilatation, bone cement injection and soon after surgery were significantly different between the 2 groups (t=4.405, P=0.000; t=2.481, P=0.016; t=2.992, P=0.004, respectively). The willingness to undergo reoperation was significantly different between 2 groups (χ2=6.020, P=0.049), whereas the complications showed no significant difference (χ2=0.000, P=0.754). Conclusions: Traditional local anesthesia combined with vertebral anesthesia was effective in alleviating perioperative pain during PKP. No serious complication was noted during the operation. Level of Evidence: Level I.
Background Unsafe induced abortion is one of the most medical and public health problems in developing countries including Ethiopia. Ethiopia has permitted abortion in specific legal circumstances when the conception of the fetus is caused by rape, incest, when continuation of pregnancy endangers the mother’s life. The aim of this study is to assess the magnitude and associated risk factors of unsafe induced abortion among women who received post abortion care service in Fitche Hospital. Methods Institutional based cross-sectional study was carried out among women who received post abortion care service at Fitche hospital from November 30, 2017 up to May 30, 2018. The data was collected using pre tested questionnaire and entered to EpiData version 3.1 software and analyzed using SPSS version 24. Descriptive statistics, multivariate logistic regression analysis and chi-square test were conducted. Results Three hundred and eight respondents (100% response rate) with mean age of 30 ± 9 years were participated in this study. From respondents, 45% had history of unsafe induced abortion and 27% of them reported the abortion was performed in house by traditional birth attendant. Single women were more likely practice unsafe induced abortion than widowed women [OR: 9.71; 95%CI (1.30 – 72.42)]. Women who had low monthly income [OR: 6.72; 95%CI (2.15 - 20.97)] and house wives [OR: 12.29; 95%CI (1.70 - 88.63)] were more likely practice unsafe induced abortion than counterparts. Failure of contraceptive methods, place of interference, method used for interference, a person who induced the abortion, a condition after procedure, and reasons to induce abortion were identified as association factors of unsafe induced abortion at P < 0.001. Conclusion The study assessed the magnitude and reported a significant association between unsafe induced abortion and socio-demographic factors, contraceptive practice, and abortion related items. These findings are positive enough to warrant a large-scale study to better understand the unsafe abortion vulnerability factors in Ethiopia.
