ObjectivesWe hypothesized that the laparoscopic implantation of neuroprosthesis (LION) procedure would significantly alter the body composition of patients with chronic traumatic spinal cord injury (SCI). The objectives were to determine the effect of the LION procedure on lean mass (LM), fatty mass (FM), and bone mineral content (BMC) in patients with SCI.Materials And MethodsFive consecutive patients underwent dual-energy x-ray absorptiometry scans before the LION procedure and at the one-year postoperative follow-up to determine changes in LM, FM, and BMC. Student paired t-test was used to determine significance.ResultsThe patients gained 2506 ± 565 g of LM in the legs (p < 0.001), which was an 18% total increase in leg LM. Total body LM was significantly increased by 3523 ± 1048 g (p < 0.003). FM was unaffected, whereas total BMC showed a small but significant increase of 99 ± 42 g (p = 0.009).ConclusionsThe LION procedure and subsequent neurostimulation procedures resulted in substantial increases in leg LM in patients with chronic traumatic SCI and paraplegia. A possible incremental effect on total BMC also was observed. Further studies are needed to confirm and expand these promising results.Copyright © 2022 International Neuromodulation Society.
