Purpose: Sagittal imbalance of severe adult degenerative deformities requires surgical correction to improve pain, mobility and quality of life. Our aim was a harmonic and balanced spine, treating a series of adult degenerative kyphoscoliosis by a nonposterior subtraction osteotomy technique. Extreme lateral (XLIF) and transforaminal (TLIF) interbody fusion were used to restore lumbar lordosis and mobilize the coronal curve, while grade 2 osteotomy (SPO) was useful to further decrease kyphosis.

Methods: We operated 22 thoraco-lumbar and lumbar degenerative deformities, characterized by a sagittal compensated (hidden) imbalance (SVA<50 mm), with or without coronal deformity, and distinguished according to the SRS-Schwab classification. All patients were submitted to X-ray screening during pre, post-operative and follow-up periods.

Results: Mean age was 65.3 (50-74; M/F 1: 4). Sixteen deformities were type L and 6 type N. Loss of LL was moderate (+) in 14 cases and marked (++) in 8. We performed 39 XLIFs, 8 TLIFs, 32 SPOs. Complication rate was minimal. Pelvic tilt, lumbar lordosis, sagittal vertical axis and thoracic kyphosis improved (p<0.05), post-operative values were similar to those pre-operatively calculated in 90% of cases and clinical follow-up (mean 20.5; range 18- 24), scored using VAS and ODI, was satisfactory in all cases, except for two due to sacro-iliac pain.

Conclusion: Current follow-up does not allow definitive conclusions. However, the surgical approach reported seems to be a viable choice usable in these compensated adult deformities, avoiding risks and complications of more aggressive pedicle subtraction osteotomies.
