Osteoporosis drugs are prescribed to prevent fragility fractures, which is the principal aim of the management of osteoporosis. However, if fracture does occur, then it is also important to promote a fast and uneventful healing process. Despite this, little is known about the effect of osteoporosis drugs on bone healing in humans. Strontium ranelate is an osteoporosis agent that increases bone formation and reduces bone resorption and may therefore be beneficial in fracture healing. We report four cases of fracture non-union for up to 20 months. Treatment with strontium ranelate (2 g/day) for between 6 weeks and 6 months appeared to contribute to bone consolidation in the four cases. Animal studies support beneficial effects of strontium ranelate on bone healing via improvement of bone material properties and microarchitecture in the vicinity of the fracture. The clinical cases described herein provide new information on these effects, in the absence of randomized controlled studies on the clinical efficacy of pharmacological treatments in osteoporosis in fracture repair. Further studies are necessary. Fracture healing is an important topic in orthopedic research and is also a concern for patients with postmenopausal osteoporosis. Evidence from case reports and animal studies suggests that strontium ranelate improves bone microarchitecture and accelerates fracture healing. A positive effect of osteoporosis treatments on bone healing is an interesting possibility and merits further clinical research.
A Doença de Dupuytren observa-se com frequência nesta região. Dada a sua incidência, a diminuição da capacidade de trabalho que pode provocar e o elevado número de casos tratados cirurgicamente, decidimos reavaliar os pacientes, tentando identificar factores etiológicos e o resultado do tratamento.Foi efectuado um estudo de revisão clínico e de registos em processo de 100 casos, operados entre Fevereiro de 2002 e Dezembro de 2005 no Serviço de Ortopedia do Hospital do Vale do Sousa.Após discussão com os ortopedistas assistentes, todos os dados relevantes recolhidos foram tratados estatisticamente em colaboração com o Serviço de Bioestatística da Faculdade de Medicina do Porto.Os resultados são precedidos de uma perspectiva histórica e um sumário da etiologia, evolução, estadiamento, classificação e opções de tratamento da doença de Dupuytren.
