Trauma of the wrist is often responsible for multiple ligament injuries. We wanted to know if the association of a luno-triquetral ligament lesion and a triangular fibrocartilage disc lesion has a poor prognosis. We reviewed 32 patients with a traumatic injury of the triangular ligament, with a mean age of 35 years, and 32 months of follow up. The functional scores used were the Modified Mayo Wrist score, the Quick DASH score, and the Herzberg score. Patients were classified according to the severity of luno-triquetral lesions, in conformity with the Geissler's classification. Ten patients had a healthy ligament, 11 a stable lesion stage 1 and 11 an unstable lesion stage 2, 3 or 4. The joint mobility averages were 59.5° in flexion, 64.2° in extension, a pronation of 71.3°, a supination of 74.1°, an ulnar inclination of 33.8° and a radial inclination of 16.8°. The Modified Mayo Wrist score average was 75/100, the Herzberg score average was 81.5/100 and the average of the Quick DASH 8/100. The patients were all very satisfied or satisfied with their intervention. There was no statistically significant difference between the three groups studied regarding mobility and functional scores. In this study, an associated luno-triquetral ligament injury does not seem to worsen the functional outcome after surgery, provided appropriate treatment had been performed. However, a larger patient sample is needed to verify these findings. 相似文献

BACKGROUNDThere has been an increase in cases of inflammatory bowel disease (IBD) in recent years. There is also greater access and availability of immunosuppressive and biological agents, which increase the risk of opportunistic infection despite improving the quality of life and promoting mucosal healing. Tuberculosis (TB) remains a public health problem, and it has a high incidence in several countries. Therefore, knowledge of the risk of developing TB in patients with IBD is important.AIMTo evaluate the risk of active TB in patients with IBD under treatment from an endemic area in Latin America.METHODSA standard questionnaire included demographic variables, clinical aspects of IBD disease, history of active TB during treatment, active TB characteristics and evolution, initial screening and results and time from the start of anti-tumor necrosis factor alpha (TNFα) to TB development.RESULTSAzathioprine, anti-TNFα and the combination of these two drugs were associated with a higher risk of active TB incidence. The TNFα blockers increased the relative risk of developing active TB compared to other treatments. All four multivariable models showed that the use of TNFα blockers alone or in combination with azathioprine was an important risk factor for the incidence of active TB. After adjustment for sex, age, type of IBD and latent TB, anti-TNFα with azathioprine increased the relative risk to 17.8 times more than conventional treatment. Late TB, which was diagnosed 3 mo after the start of anti-TNFα, was the most frequent.CONCLUSIONTreatment with anti-TNFα increased the risk of active TB in IBD patients from an endemic area in Latin America. This risk was increased when anti-TNFα was combined with azathioprine. The time from the beginning of the treatment to the active TB diagnosis suggests a new TB infection. 相似文献
