Osteosynthesis of bilateral Vancouver B2 periprosthetic femoral fracture after ...
Ferreira, Isabel Dinis; Mariano, João Cura; Lucas, Francisco M.; Judas, Fernando M.INTRODUCTION: The management of periprosthetic femoral fractures following hip arthroplasty is chal-lenging, and the choice between osteosynthesis of the fracture and the revision of the prosthesis is stillmatter of discussion.CASE REPORT: In a 81-year-old male patient, a bilateral Vancouver type-B2 periprosthetic femoral fracturewith stem loosening occurred after an accidental fall. The patient had severe medi...
Fracture characterization of human cortical bone under mode II loading using th...
Silva, F. G. A.; Moura, M. F. S. F. de; Dourado, N.; Xavier, J.; Pereira, F. A. M.; Morais, J. J. L.; Dias, M. I. R.; Lourenço, Paulo J.Fracture characterization of human cortical bone under mode II loading was analyzed using a miniaturized version of the end-notched flexure test. A data reduction scheme based on crack equivalent concept was employed to overcome uncertainties on crack length monitoring during the test. The crack tip shear displacement was experimentally measured using digital image correlation technique to determine the cohesiv...
Stable fixation of a madreporic Lord femoral prosthesis at 31-year follow-up in...
Judas, Fernando M.; Ferreira, Joana Fonseca; Dias, Rui Freitas; Lucas, Francisco M.INTRODUCTION: Lord total hip prosthesis was discontinued due to high revision rates of the smooththreaded acetabular component and negative effects of stress shielding in the proximal femur.PRESENTATION OF CASE: We report the outcome of a Lord cementless femoral stem, in a 55-year-oldwoman. In 1984, the patient underwent a Lord total hip arthroplasty for the treatment of advanced dys-plastic osteoarthritis of t...
Bone turnover markers for early detection of fracture healing disturbances: A r...
Sousa, Cristina P.; Dias, Isabel R.; Lopez-Peña, Mónica; Camassa, José A.; Lourenço, Paulo J.; Judas, Fernando M.; Gomes, Manuela E.; Reis, Rui L.Imaging techniques are the standard method for assessment of fracture healing processes. However, these methods are perhaps not entirely reliable for early detection of complications, the most frequent of these being delayed union and non-union. A prompt diagnosis of such disorders could prevent prolonged patient distress and disability. Efforts should be directed towards the development of new technologies for...
