Musculoskeletal manifestations of mild osteogenesis imperfecta in the adult

Abstract

The musculoskeletal manifestations of mild forms of osteogenesis imperfecta are not well defined in the adult. The aim of this study was to characterize the musculoskeletal manifestations and resulting impairments reported by adults with mild osteogenesis imperfecta. For this task a survey of musculoskeletal symptoms and impairments was hosted on the Osteogenesis Imperfecta Foundation web site for 6 weeks. Survey responses are reported herein. There were 111 unduplicated, adult respondents (78 female). Mean age was 40.8 years. More than one-quarter of 3,410 lifetime fractures occurred in adulthood. Nearly half of respondents reported an established diagnosis of "arthritis" (usually osteoarthritis), and the majority of these reported some degree of impairment attributable to arthritis. Articular pain, stiffness and instability were dominant in the large, weight-bearing joints of the lower extremities. Back pain and scoliosis were common. Of the respondents, 15% required assistance with light physical tasks and personal care. Two-thirds reported joint hyper-mobility, and one-third reported a previous tendon rupture. Complex regional pain syndrome was rare. Respondents reported frequent use of medications known to have potential adverse skeletal effects. In spite of these concerns the majority rated their overall physical health as good or excellent. Adults with mild osteogenesis imperfecta continue to sustain fractures into adulthood, and the majority reports some functional impairment due to musculoskeletal issues. Significant impairment is not rare.
