Abstract
Introduction: Complete spinal cord injury patients demonstrate an initial rapid lower limb bone mineral density loss.1,2; Reports suggest an increase incidence of lower limb fractures in such patient.3 Such injuries place an additional burden on patients undergoing rehabilitation.
Aims: This prospective study was established to assess whether disuse osteopenia contributes to increased incidence of lower limb fractures in patients following complete spinal cord injury. We compare this cohort to patients who attained mobility after their spinal cord injury.
Methods: We prospectively reviewed 128 patients (107 male; 21 female) treated in our unit, a Tertiary Referral Spinal Trauma Unit. All patients presented between January 1994 and July 2002. There were 66 patients 958 male; 8 female) who initially presented to this unit and subsequently attained mobility either while in hospital or during rehabilitation. Both groups were comparable in age and sex profiles.
Results: The mean length of follow-up was 58 months for patients with complete neurology and 64 months for those who attained mobility. There were 4 lower limb fractures in the group of patient with complete neurology. Two patients sustained supracondylar femoral fractures with one requiring operative intervention, while 2 patients with mid-shaft tibia/fibula fractures were treated conservatively.
Conclusions: Previous papers have shown that patients with complete neurology after spinal injury undergo disuse osteopenia. We report an increase incidence of lower limb fractures in patients with complete neurology compared to patients initially presenting with neurology but attaining full mobility. This difference is statistically significant, (p< 0.05).
