A/B: Standing full spine x-ray preoperative antero-posterior and sagittal view. A: No coronal imbalance or angular deformities showed in AP view. B: Sagittal view: Multiples vertebral fractures were observed in thoracic, lumbar and consecutives in thoracolumbar area leads to TLK (T10-L2) 25  and sagittal vertical axis (SVA) 13 cm. C/D/E/F: TC preoperative sagittal view shows loss of vertebral body height and kyphosis in thoracolumbar area and sagittal views of MR T1, T2-weighted and STIR sequences without oedema suggesting acute lesion.

Magnetic resonance (MR) confirmed multiple vertebral fractures without malignant signs, which suggested osteoporotic fractures (Fig. 1). Pelvic parameters: Pelvic incidence (PI) 40 , sacral slope (SS) 25  and pelvic tilt (PT) 15  (Fig. 1).
DXA changes through follow-up. Dual energy X-ray absorptiometry (DXA) recovered a normal value in the L2-L4 lumbar spine (T-score 1.4) and an osteopenic value in the hip (T-score -1.9) at six years of follow-up.

Dual energy X-ray absorptiometry (DXA) showed osteoporosis in spine and hip (lumbar spine T-score -2.7 and femoral neck T-score -3.1) (Fig. 2). X-ray absorptiometry (DXA) recovered a normal value in the L2-L4 lumbar spine (T-score 1.4) and an osteopenic value in the hip (T-score -1.9) at six years of follow-up (Fig. 2). X-ray study showed an adequate SVA 6.9 cm, TK (T2-T12) of 28 , and TLK (T10-L2) 16  and LL of 36  (Fig. 3).
A/B: Standing full spine x-ray postoperative antero-posterior and sagittal view. C/D: Coronal and sagittal views at end of follow-up, showing T10-L3 arthrodesis with fenestrated screws and PMMA, adequate balance, well positioned implants without osteolysis or proximal junctional faillure. E/F/G: MR T1, T2-weighted and STIR sagittal sequences don't show news fractures at six-years of follow-up.
