RESUMO
Objective The purpose of the present study is to compare intraoperative blood loss, operating time, laminectomy time, hospital length of stay, and complications in thoracolumbar spinal decompression using ultrasonic bone scalpels (UBSs) with conventional procedures. Methods Forty-two patients who underwent decompressive laminectomy and pedicular screw fusion with a surgical level of 1-5 levels between February 1, 2020, and June 30, 2022, in a single institution were evaluated for eligibility, and 11 were excluded due to a history of spinal surgery ( n = 3), spinal tumor ( n = 3), and spinal infection ( n = 5). A total of 31 patients were randomly divided into the UBS group ( n =15) and the conventional group ( n =16). Intraoperative blood loss, operating time, laminectomy time, hospital length of stay, and complications were recorded. Results Intraoperative blood loss and laminectomy time were significantly lower in the UBS group (656.0 ± 167.6 ml, 54.5 ± 27.4 minutes, respectively) than in the conventional group (936.9 ± 413.2 ml, 73.4 ± 28.1 minutes, respectively). Overall operation time, hospital length of stay, and complications were all similar between the groups. Conclusion The UBS is a useful instrument for procedures performed near the dura mater or other neural tissue without excessive heat or mechanical injury. This device is recommended for various spinal surgeries in addition to high-speed burrs and Kerrison rongeurs.

Resumo Objetivo O objetivo do presente estudo é comparar perda de sangue intraoperatória, tempo de operação, tempo de laminectomia, tempo de internação hospitalar e complicações na descompressão espinhal torácica utilizando bisturis ósseos ultrassônicos (BOUs) em relação aos procedimentos convencionais. Métodos Quarenta e dois pacientes submetidos a laminectomia descompressiva e fusão pedicular do parafuso com um nível cirúrgico de 1 a 5, entre 1° de fevereiro de 2020 e 30 de junho de 2022 em uma única instituição, foram avaliados para elegibilidade e 11 foram excluídos devido ao histórico de cirurgia espinhal (n= 3), tumor espinhal (n= 3) e infecção espinhal (n= 5). Perda de sangue intraoperatória, tempo de operação, tempo de laminectomia, tempo de internação e complicações foram registradas. Resultados A perda de sangue intraoperatória e o tempo de laminectomia foram significativamente menores no grupo BOU (656,0 ± 167,6 ml, 54,5 ± 27,4 min, respectivamente) do que no grupo convencional (936,9 ± 413,2 ml, 73,4 ± 28,1 min, respectivamente). O tempo de funcionamento total, o tempo de internação e as complicações foram todos semelhantes entre os grupos. Conclusão O bisturi ósseo ultrassônico é um instrumento útil para procedimentos realizados próximos à dura-máter ou outro tecido neural sem calor excessivo ou lesão mecânica. Este dispositivo é recomendado para várias cirurgias de coluna vertebral, juntamente com rebarbas de alta velocidade e pinça Kerrison.
