“…Several techniques have been described to minimize cement leakage during PVP, such as the use of balloon catheters to control cement flow or the use of polyetheretherketone (PEEK) coiled metallic implants (6). Some authors use combined techniques with ablation in association with cement injection for the treatment of bone fracture and impending fracture (21).…”

“…During PVP, polymethylmethacrylate (PMMA) cement is injected percutaneously through a needle to fortify a pathological fracture or consolidate a lytic tumor. Although PVP is a safe technique, some complications may occur with cement leakages being the most frequent complication (5,6). Most cement leakages are not associated with serious complications such as paravertebral soft tissue leaks and discal leaks.…”

“…Breast cancer, injected volume of cement, and vertebral collapse were also reported risk factors of cement leakage during PVP for spine metastases (10,11,13). The treatment of cement leakage is usually conservative with anti-inflammatory agents while surgical removal may be pursued in patients with persistent symptoms (6).…”

Background Percutaneous vertebroplasty (PVP) is an effective measure for painful metastases or impending pathological fractures of the spine with cement leakages being the most frequent complication. Posterior extrusion of cement into the spinal canal may result in neurological symptoms and deficits. Purpose To compare the occurrence of intraspinal canal cement leakage between vertebrae with posterior wall disruption and vertebrae without posterior wall disruption. Material and Methods A single-center retrospective study was conducted of all PVP for spine metastases between June 2020 and November 2021. All leaks were analyzed by a postprocedural computed tomography scan or cone-beam computed tomography. Results A total of 77 patients with 143 vertebrae treated by PVP were included. Posterior wall disruption was observed in 64 (44.8%) vertebrae while 79 (55.2%) had a complete posterior wall. Spinal canal cement leakage occurred in 36 (25.2%) vertebrae and was comparable in both groups, occurring in 16 (25.0%) vertebrae with posterior wall disruption and 20 (25.3%) vertebrae without posterior wall disruption ( P = 1). No risk factors for spinal canal leakage were found in the univariate and multivariate analyses. One spinal leak was symptomatic with intercostal neuralgia. Conclusion Our results suggest that an incomplete vertebral posterior wall does not increase the rate of spinal canal cement leakage during PVP.
