Hidatidose do esterno e musculatura peitoral Sternal and pectoral musculature hydatidosis

A hidatidose é uma infecção ciclozoonótica causada pela tênia Echinococcus granulosus, cuja forma larvária acomete acidentalmente o homem, formando cistos hidáticos, preferencialmente nos pulmões e no fígado. A hidatidose óssea é um evento raro, caracterizado por crescimento lento e com poucos sintomas. Relata-se o caso de um homem de 36 anos com história de nódulos na parte anterior do tórax havia nove anos. Os exames de diagnóstico por imagem evidenciaram massas expansivas, loculadas e de conteúdo espesso nos músculos peitorais e lesão lítica no esterno. O diagnóstico de hidatidose foi feito na exploração cirúrgica. Recebeu alta sob tratamento com albendazol 2.400mg/dia por 28 dias.<br>Hydatidosis is a cyclezoonotic infection caused by taenia Echinococcus granulosus, whose larval form accidentally affects men by forming hydatic cysts preferably in the lungs and liver. Osseous hydatidosis is a rare event characterized by slow growth and few symptoms. It is reported on a 36-year-old man who had presented nodes in the anterior thorax for nine years. Imaging diagnostic examinations revealed thick, loculated, expansive masses in the pectoral muscles and sternal lytic lesions. The diagnosis of hydatidosis was established by exploratory surgery. The patient showed good clinical-surgical evolution and was discharged receiving albendazole, 2,400 mg/day, for 28 days

Long-term results of the direct repair of spondylolisthesis

Direct repair of spondylolisthesis can save a functional segment in young patients with slight slipping. Since 1968 many surgeons have proposed different technical solutions to obtain the isthmic repair. Their results changed according to the technique used, the extent of listhesis and the age of the patient. The aim of our study was to perform a retrospective review on the long-term results of the direct repair of spondylolisthesis, according to the different techniques used. We operated 62 patients for isthmic repair, with three different techniques, from 1994 to 2007. We analysed the clinical and radiographic results of 52 cases, with an average follow-up of 9 ± 3 years (range 2–15). Ten patients were lost to the follow-up. The results were different depending on the technique used. Good or excellent clinical outcome by Odom’s criteria were observed in the 83.3% of patients operated with the modified Scott technique. These results are better than those obtained in the group of patients operated with the Scott (62.5%) and the Buck technique (28.5%). Patients with clinical and radiological failure, who then underwent spinal fusion, were 57% with the Buck technique, 12.5% with the Scott technique and 2.7% with the Scott modified technique. The reasons for a new operation were symptomatic pseudarthrosis and progression of slipping. In conclusion, the pars defect repair is a helpful technique in lumbar spondylolisthesis, especially in young patient with slight slipping and painful symptoms resistant to conservative treatment. In our experience, the modified Scott technique seems to provide a better outcome than the Scott and Buck techniques
