Recently, titanium plates (TPs) have been used instead of conventional hydroxyapatite block (HA) spacers to prevent laminar reclosure. However, no study has compared the cost-effectiveness of TP and HA. Therefore, this study aimed to compare the cost-effectiveness and postoperative outcomes of laminoplasty using TP or HA.</p><p><strong>Methods: </strong>A total of 167 patients who underwent cervical laminoplasty at our institution were included in this study. Patients with cervical spinal cord injury, epidural hematoma, or follow-up of <1 year were excluded. Of the 167 patients, 69 underwent laminoplasty using TP (the TP group), and 98 underwent laminoplasty using HA (the HA group). The surgical costs and incremental cost-effectiveness ratio (ICER) were compared between the two groups. Additionally, the operation time, complications, Japanese Orthopaedic Association score, Hirabayashi recovery rate, and pre and postoperative cervical alignment on X-ray images were investigated.</p><p><strong>Results: </strong>The surgical costs were significantly higher in the TP group than in the HA group (HA, 7255 ± 1504 USD vs. TP, 11,642 ± 2492 USD, p < 0.01). The ICER was 21,935 USD per quality-adjusted life year in the TP group. The operation time was shorter in the TP group than in the HA group (HA, 70.0 ± 22.5 min vs. TP, 63.6 ± 19.3 min, p = 0.06). The Hirabayashi recovery rate and radiographic parameters were similar between the two groups. Implant displacements were significantly more common in the HA group than in the TP group (HA, 11.2 % vs. TP, 0 %, p < 0.01).</p><p><strong>Conclusions: </strong>The surgical costs and ICER with TPs were higher than those with HA spacers.
