Comparison of clinical outcome after Percutaneous Vertebro Plasty (PVP) for Osteoporotic Vertebral Compression Fractures (OVCFs) between patients with and without Intra Vertebral Clefts (IVCs). PVP is a common treatment modality for painful OVCFs. Patients presenting with OVCFs with an IVC, also described as avascular necrosis of the vertebral body or intravertebral pseuadoarthrosis, are thought to represent a specific subgroup: filling the cleft might result in immediate and possibly superior pain relief due to stabilization of the excessive mobility associated with an IVC and the risk for cement leakage might be decreased due to its cavitational nature.Objective
Background
Multiple logistic analysis revealed no definitive predictive factors for the occurrence of cement leakage (yes/ no) (Odds Ratio [95% CI], P):
Severity (acc to Genant et al): 1.82 [0,69 – 4.89], 0.229 Fracture Type (Genant et al): 1.22 [0.64 – 2.32], 0.550 Injected Volume: 0.98 [0.76 – 1.27], 0.875 Spinal Region: 0.87 [0.48 – 1.55], 0.628 Cement Viscosity: 0.42 [0.16 – 1.10], 0.076
Analysis of vertebral morphometrics with emphasis of the vertebral wedge angle and height of the vertebral body at the anterior, center and posterior border. Determining the loss and gain of height of the vertebra with OVCF pre- and post-PVP up to one year, using pre-PVP estimated heights.
