Screw assisted internal fixation (SAIF) represents a definite advancement in the treatment of vertebral compression fractures (VCFs), especially in fractures with a greater degree of instability. The manuscript by Cianfoni et al discusses the use of SAIF in treating patients with VCFs involving the middle-column (MC), the pedicles and burst-type fractures.1 This report documents significant success not only in reducing their pain and improving their clinical condition but also in maintaining structural integrity.1

Fractures involving the posterior wall, the pedicle-vertebral body junction and low energy burst fractures are common and represent fractures that need to be treated with a greater amount of anterior and middle column support than typical anterior column only fractures. In patients with poor bone quality, inadequate fixation can lead to refracture of the incident level with displacement of cement and significant worsening of the patient’s condition.2–4 This is almost always …
