A semi-rigid thoracolumbar orthosis fitted immediately after spinal surgery : stabilizing effects and patient satisfaction.

Purpose : To evaluate the stabilizing effects of a Fit Cure-Spine® semi-rigid thoracolumbar orthosis and wearer satisfaction after lumbar surgery.

Methods

In study 1, the spinal angle, spinal motion angle, and distribution of load were measured in 8 adult male volunteers when the orthosis was worn (1) with no custom-made stay (CMS), (2) with a CMS in the prone position (P-CMS), and (3) with a CMS in the prone position and decreased lordosis (DP-CMS). In study 2, pain scale scores and responses to a questionnaire were recorded in 40 consecutive patients who underwent lumbar spinal surgery in our hospital.

Results

In study 1, the mean lumbar lordosis when standing was similar to that in the prone position. When the trunk was bent forward, loads on the back support in P-CMS and DP-CMS were concentrated at the center of the CMS, unlike those for No-CMS. In study 2, there was a significant decrease in postoperative wound pain after wearing the Fit Cure-Spine orthosis for 2 weeks. Most patients who wore the orthosis were satisfied with their pain outcome.

Conclusion

Adjustment to lumbar lordosis and the prone position was restricted in volunteers wearing the Fit Cure-Spine with a CMS. J. Med. Invest. 66 : 275-279, August, 2019.
