Background:
Type 4 osteoporotic fracture (OF4), according to the classification system of the Spine Section of the German Society for Orthopaedics and Trauma (DGOU), is unstable and requires fixation as per the guidelines of the same group. We evaluated the use of stand-alone vertebral body augmentation (VBA) in pain control of OF4.
Methods:
This is a single-centre, in two hospitals, comparative study to evaluate the effectiveness of percutaneous vertebroplasty (PVP) and kyphoplasty (KP) in pain control of OF4. OF4 patients treated with VBA were compared to a conservatively treated control group. The two groups of OF4 were then compared to similar cohort of OF2 and OF3 patients who were treated by either VBA or expectantly.
Results:
A total of 78 cases were studied. VBA of OF4 showed a statistically significant better pain control than conservative treatment. The response of this group of fractures to VBA was similar to that of OF2 and 3.
Conclusion:
VBA can provide satisfactory pain control for OF4 patients.
