Abstract

Purpose

The aim of this study was to assess the clinical efficacy of balanced halo-pelvic traction (HPT) and evaluate its contribution to the correction surgery in treating adult severe rigid spinal deformity.

Methods

One hundred and eight adult patients with severe rigid spinal deformity who underwent preoperative HPT and correction surgery were reviewed. The main coronal curve, segmental kyphotic angle, coronal balance (CB), sagittal balance (SVA), and the length of spine were measured before HPT, after HPT, post-operatively, and at final follow-up. The HPT contribution rates to deformity correction were calculated.

Results

The pre-HPT main coronal curve was 103.4 ± 10.6°, improved to 61.0 ± 13.4° after traction and further improved to 44.2 ± 10.2° after surgical correction, and maintained at 50.3 ± 9.9° at final follow-up. CB started at 4.2 ± 4.8 cm, improved to 2.1 ± 2.5 cm after HPT, 0.8 ± 1.2 cm after operation, and 0.7 ± 0.9 cm at final follow-up. The pre-HPT sagittal segmental kyphotic angle was 67.3 ± 17.7°, was then improved to 42.2 ± 27.5° after traction and further improved to 34.9 ± 10.2° after surgery, and maintained at 35.4 ± 10.4° at final follow-up. The length of spine improved from 35.9 ± 5.9 to 42.6 ± 6.0 cm via HPT, reached up to 45.0 ± 6.0 cm after operation, and maintained at 44.3 ± 5.2 cm at final follow-up.

Conclusion

HPT is effective for the treatment of severe rigid spinal deformity. Balanced HPT can dramatically improve coronal and sagittal deformity as well as spinal length before corrective surgery.
