Orthopedics The non-union of 2 fractured ends of a long bone, in which the bone is covered by fibrous tissue or fibrocartilage; in extreme cases, the false joint is surrounded by a bursal sac containing synovial fluid; congenital PAs may occur in von Recklinghausen's disease or osteogenesis imperfecta; acquired PA usually follows trauma or, less commonly, tumor-related osteolysis and fibrous dysplasia. Cf Arthritis.
