Vertebral body reconstruction system B-Twin®


Kyphoplasty and percutaneous vertebroplasty are two effective procedures for osteoporotic vertebral compression fractures, but there have been few publications on their use in non-osteoporotic forms. B-Twin® vertebral body reconstruction is a new minimally invasive vertebral body reconstruction technique developed for non-osteoporotic vertebral compression fractures of the thoracolumbar junction and lumbar spine.


The present study describes this novel technique and assessed efficacy compared to a conservative method.

Patients and methods

Inclusion criteria were: Magerl type A1.2 non-osteoporotic thoracolumbar or lumbar spinal compression fractures in patients aged over 18 years, free of neurologic compromise. Patients were randomized to management by corset (group 1) or by the B-Twin® spacer (group 2). Follow-up used a visual analog scale (VAS) to assess pain, the Oswestry Disability Index (ODI) and, on radiology, the vertebral (VK) and regional (RK) kyphosis angles and anterior and medial height indices at baseline, 3 months and 12 months.


The vertebral body reconstruction technique provided anatomic vertebral body reconstruction and quick return to household activity without resort to a corset. Deformity was durably reduced. At 12-month follow-up, pain reduction and stasis were achieved. The risk of injected cement leakage was slight.
