RESUMEN
Lesions to the shoulder rotator cuff may have several configurations, and are divided and classified according to the size of the lesion, the tendon involved, its combinations and whether there is possibility of repair. Irreparable subscapular lesions, as well as irreparable anterosuperior lesions, may generate shoulder dysfunction due to loss of humeral head depressants, causing pain and functional limitation. Myotendinous transfers are among the therapeutic alternatives, and the most studied and widespread in recent decades is the transfer of the pectoralis major to the minor tuberosity. However, some anatomical studies suggest that the latissimus dorsi is a more appropriate alternative for the treatment of these lesions because it presents force vectors more similar to those of the subscapularis, besides presenting promising results in the clinical evaluations with short follow-up. The present work aims to describe the surgical technique developed for transfer of the latissimus dorsi in cases of irreparable subscapular and anterossuperior lesions to the rotator cuff.
RESUMEN
Objective To evaluate radiographically the postoperative results of patients with fracture of the proximal humerus in two parts of the surgical neck treated with threaded percutaneous fixation. Methods We evaluated the radiographic results of percutaneous fixation with threaded pins on the treatment of proximal humerus fractures in our service. Preoperative and postoperative images of 42 patients were evaluated, evaluating radiographs until 8 weeks postoperatively. We considered on evaluation the fracture deviation on preoperative images, the loss of reduction and no consolidation. Results Our consolidation rate was 90.4%, with loss of reduction in 16.6% of the cases and no consolidation rates in just 4 operated cases. We observed a predominance of a specific fracture pattern in the cases with loss of reduction. Conclusion The present study allows us to consider the percutaneous fixation technique with threaded pins as an alternative in our therapeutic arsenal for the proximal humerus fracture of the surgical neck. Contraindications are considered for low fracture trait on the metaphysis and with medial/lateral cortical impairment.

Resumo Objetivo Avaliar radiograficamente os resultados pós-operatórios dos pacientes com fratura da extremidade proximal do úmero em duas partes do colo cirúrgico tratados com fixação percutânea com fios rosqueados. Métodos Avaliamos radiograficamente os resultados da fixação percutânea com fios rosqueados das fraturas da extremidade proximal do úmero realizadas em nosso serviço. Foram avaliadas as imagens pré- e pós-operatórias de 42 pacientes, avaliando-se radiografias com até 8 semanas de pós-operatório. Consideramos na avaliação o desvio da fratura pré-operatório, a perda da redução e a consolidação da fratura. Resultados O índice de consolidação nos casos avaliados foi de 90,4%, com perda da redução em 16,6% dos casos e não obtida a consolidação em apenas 4 casos. Foi observada uma predominância de determinado padrão de fratura nos casos que perderam a redução. Conclusão O estudo permitiu considerar a técnica de fixação percutânea com fios rosqueados uma alternativa no arsenal terapêutico da fratura da extremidade proximal do úmero do colo cirúrgico, com contraindicação para os traços de fratura baixos na metáfise e com acometimento da cortical medial/lateral.
