    Fracture threshold in the femur and tibia of people with spinal cord injury

    Bone mineral density (BMD) can be used to identify people who are at risk of sustaining leg fractures.

    Eser P, Frotzler A, Zehnder Y and Denoth J (2005). Fracture threshold in the femur and tibia of people with spinal cord injury as determined by peripheral quantitative computed tomography. Arch Phys Med Rehabil 86: 498-504. Abstract Eser P, Frotzler A, Zehnder Y, Denoth J. Fracture threshold in the femur and tibia of people with spinal cord injury as determined by peripheral quantitative computed tomography. Objective To determine bone traits of the femur and tibia with peripheral quantitative computed tomography (pQCT) that best distinguish between spinal cord injury (SCI) subjects with and without fractures. Design Cross-sectional study. Setting In- and outpatient paraplegic center in Switzerland. Participants Ninety-nine motor complete SCI subjects (duration of paralysis, 2mo-49y), 21 of whom had sustained fractures of the femur or tibia. Interventions Not applicable. Main outcome measures Subjects with SCI were questioned about the occurrence, location, and approximate date of fractures to their lower extremities. Trabecular and cortical bone mineral density (BMD), as well as bone geometric properties of distal epiphyses and midshafts of the femur and tibia, were measured by pQCT. Results Trabecular BMD of the femur and tibia distal epiphyses was found to distinguish best subjects with fractures from those without. Fractures occurred in subjects with trabecular BMD of less than 114mg/cm 3 and less than 72mg/cm 3 for the femoral and tibial distal epiphysis, respectively (corresponding to 46% and 29% of mean values of an able-bodied reference group). Approximately 50% of the subjects with chronic SCI (defined as time postinjury >5y for femur data and >7y for tibia data) had trabecular BMD values above the fracture threshold in the femur and about one third above the fracture threshold in the tibia. Conclusions By using pQCT, it may be possible to identify subjects with SCI who are at risk of sustaining fractures of the femur and tibia through minor trauma.

    Good info to pass on to my doc. Whats the name of that drug CR used to rebuild his bone density?

    It is no drug who can rebuild the bones of people with SCI, the usual drug for osteoporose does not work. The only thing that helps is to stand up for at least 30 minutes everyday.

    I just been in the rehab and I was asking my doctor there.

    Perhaps Fosamax?
