ABSTRACT This work evaluates the normative and legal compliance related to the human harnesses used by tactical flight officers in the institutional missions conducted by the Brazilian Public Air Units (UAPs), regulated by the Brazilian Civil Aviation Regulation (RBAC) no. 90. The study bases its analysis on the identification of regulatory obstructions that limit the performance of the Brazilian State, from the operational and aeronautical product certification standpoints, as well as on the demonstration of legal risks to the current operational context adopted by the units. The use of inappropriate human harnesses has shown to be a contributing factor to aviation occurrences and fatalities in Brazil. This research delivers a regulatory alternative with a view to greater operational flexibility, legal safeguards and increased safety for the UAPs and entities that employ air transportation as a tool for their institutional activities.

OBJETIVO: Avaliar o resultado retrospectivo de 12 pacientes submetidos ao reparo artroscópico de lesões completas isoladas do tendão do subescapular com seguimento mínimo de um ano. MÉTODOS: De 11 de abril de 2002 a 24 de setembro de 2004, realizou-se o reparo artroscópico de lesões completas do manguito rotador em 95 pacientes no Instituto Balsini. Pacientes com subescapular lesado somavam 31; 12 lesões isoladas compunham o grupo de estudo. Foram reavaliados com seguimento mínimo de um ano da cirurgia, considerando grau de elevação anterior ativa, escala da UCLA e satisfação do paciente. RESULTADOS: A elevação anterior ativa pré-operatória atingiu a média de 102º, o grau de elevação anterior ativa pós-operatória obteve a média de 175º. O ganho médio na elevação anterior ativa foi de 73º (p < 0,0001). O UCLA pré-operatório teve a média de 15,25 pontos e o pós-operatório atingiu a média de 31,66 pontos. O índice da UCLA médio foi de 16 pontos (p < 0,0001); 10 resultados excelentes, um bom e um mau. Resultados considerados satisfatórios foram 11 e um, insatisfatório. CONCLUSÕES: 1) A sutura artroscópica das lesões do subescapular apresenta resultados satisfatórios em 91,67% dos casos, para as lesões isoladas do terço superior e as lesões completas totais; 2) A instabilidade do bíceps é achado comum; 3) A sutura artroscópica do subescapular é possível mesmo nos tendões retraídos; 4) É uma técnica segura; 5) As lesões completas do terço superior do subescapular são sintomáticas e devem ser tratadas como tal.

OBJECTIVE: To evaluate the retrospective result of 12 patients submitted to arthroscopic repair of complete, isolated lesions of the subscapularis tendon with minimum follow-up of one year. METHODS: From April 11, 2002 to September 24, 2004, the authors performed the arthroscopic repair of complete rotator cuff lesions in 95 patients at the Balsini Institute. Patients with lesioned subscapularis amounted to 31, and 12 isolated lesions were included in the study group. They were re-analyzed with a minimum follow-up of one year after surgery to evaluate the degree of active anterior elevation, according to the UCLA scale and to patient satisfaction. RESULTS: Pre-operative active anterior elevation had a mean of 102º, and the degree of active anterior elevation after surgery presented a mean of 175º. The mean gain in active anterior elevation was 73º (p < 0.0001). Preoperative UCLA had a mean of 15.25 score points, and after surgery, a mean of 31.66 score points. The mean UCLA index was 16 score points (p < 0.0001); 10 excellent results, one good, and one poor. Satisfactory results: 10, unsatisfactory: 1. CONCLUSION: 1) The arthroscopic suture of the subscapularis lesions presents satisfactory results in 91.67% of the cases for isolated upper third lesions and for total complete lesions; 2) biceps instability is a common finding; 3) arthroscopic suture of the subscapularis is possible even in retracted tendons; 4) the technique is safe; 5) complete lesions of the upper third of the subscapularis are symptomatic and should be treated as complete lesions.
