RESUMO
Objective: Nasal fractures need timely and accurate diagnosis for required treatment to prevent future deformities and unnecessary surgery. Radiography does not provide accurate finding in this case. The aim of this study is to evaluated diagnostic efficiency of ultrasound and CT scan for acute nasal fractures. Methods: In this cross-sectional study included patients with nasal trauma referred to (XXX) from January 2020 to December 2020. Diagnostic ultrasound and CT scan was performed on all the patients and data obtained was stored in patient data collection forms along with their demographics. The data was statistically analyzed using SPSS v20. Results: Of 32 patients included in our study, 4 (12.5%) were females and 28 (87.5%) were males. The mean age of the patients was 40.28 ± 16.9 years. The specificity and sensitivity of ultrasound was 100% and 83.33%. The accuracy of the test was 93.75%. The specificity, sensitivity and accuracy were 100%, 95% and 96.88%, respectively. Chi square test also showed that there were a significant association between nose fracture and both CT scan and ultrasound, p < 0.001. Conclusion: Our study showed that both, ultrasound and CT scan are efficient for the diagnosis of nasal fractures in the patients. Further studies with greater sample size are required in this domain.
RESUMO
BACKGROUND: Total hip arthroplasty (THA) is the golden standard in treating severe osteoarthritis, which has not responded to conservative treatment. This study aimed to evaluate and compare the therapeutic results of THA using Short-stem and Standard-stem prostheses. METHODS: The study was a randomized clinical trial without a control group that was performed in 2020. A total number of 156 patients were recruited over three years. Patients were divided into two groups. The first group was treated with a Short-stem prosthesis and the second group was treated with a Standard-stem prosthesis. Patients were visited according to a schedule. At each visit, a control graph was prepared and the condition of the bone prosthesis and its position were examined. Also, the status of cane use and weightlifting were evaluated. Clinical signs such as pain, lameness, and the ability to climb stairs were assessed and recorded based on the Harris scale. Patients were also evaluated for surgical complications such as infection or limb length discrepancy. RESULTS: Data of 140 patients were analyzed. The mean age of patients was 60.2 ± 6.38 years. The amount of bleeding in the short-stem group was significantly lower than the standard-stem group (380.17 ml versus 430.13 ml, P = 0.001). In both groups, there was a significant increase in Harris score after the end of the study compared to before the operations. Furthermore, Harris's mean score was higher in the short-stem group compared to standard-stem group. However, these significant differences were observed only in the sixth week (P < 0.0001) and the third month (P < 0.0001). CONCLUSION: The use of Short-stem prosthesis in the short term can play a role in improving patient performance but in the long term evaluations, there is no apparent difference with the use of Standard-stem prostheses.
