Bisphosphonates can inhibit osteoclast-mediated bone resorption, prevent bone loss, and reduce the risk of osteoporotic fractures. The meta-analysis of studies shows that early bisphosphonate administration after spinal cord injury (SCI) was safe and beneficial to the bone mineral density (BMD) of the total hip and lumbar spine at 12 months.

Rapid bone loss in the early stages of spinal cord injury (SCI) leads to an increased risk of osteoporotic fracture. A meta-analysis was conducted to assess the efficacy and safety of bisphosphonates for the treatment of osteoporosis after SCI.

A literature search identified 9 randomized controlled trials with 206 individuals. This meta-analysis was performed using a random-effects model. The primary outcome was the percent change in bone mineral density (BMD) of the total hip, distal femur, and lumbar spine from baseline to 12 months. Bone turnover markers were secondary outcomes. The incidences of adverse events were assessed in order to evaluate safety.

Results:
--There were significant differences in BMD of the total hip and lumbar spine or serum C-terminal telopeptide between the bisphosphonate and control groups.
--The percent change in BMD of the distal femur and serum type 1 procollagen N-terminal peptide from baseline to 12 months was not superior in the treatment groups.
--Osteoclast-mediated bone resorption was inhibited by bisphosphonate administration. Subgroup analysis of participants treated with zoledronate at different sites revealed a beneficial effect on BMD of the total hip and lumbar spine but not the distal femur.

Conclusivly, early bisphosphonate administration after SCI was safe and beneficial to the BMD of the total hip and lumbar spine at 12 months.
