Biphasic calcium phosphate bioceramics for orthopaedic reconstructions: clinical outcomes.

BCP are considered the most promising biomaterials for bone reconstruction. This study aims at analyzing the outcomes of patients who received BCP as bone substitutes in orthopaedic surgeries. Sixty-six patients were categorized according to the etiology and morphology of the bone defects and received scores after clinical and radiographic evaluations. The final results corresponded to the combination of both parameters and varied from 5 (excellent result) to 2 or lower (poor result). Most of the patients who presented cavitary defects or bone losses due to prosthesis placement or revision, osteotomies, or arthrodesis showed good results, and some of them excellent results. However, patients with segmental defects equal or larger than 3 cm in length were classified as moderate results. This study established clinical parameters where the BCP alone can successfully support the osteogenic process and where the association with other tissue engineering strategies may be considered.

Estudo da imagem corporal através do teste do desenho da figura humana em pacientes portadores de necrose asséptica da cabeça femoral / The use of the human figure drawing test in the analysis of the body image in patients with avascular necrosis of the femoral head

Os autores apresentam os resultados do estudo do desenho da imagem corporal de 66 indivíduos através do teste do desenho da figura humana enquanto teste projetivo. Foram analisados os resultados de 33 pacientes portadores de necrose asséptica da cabeça femoral em relaçäo a 33 indivíduos normais. Os itens do teste do desenho da figura humana com resultados significativos foram seis no grupo estudo, enquanto que no grupo controle somente um mostrou-se significativo. Os autores concluem que o teste do desenho da figura humana foi útil para avaliaçäo da auto-imagem em pacientes portadores de necrose asséptica da cabeça femoral
