“…Another paper by Camino-Willhuber et al . compared the PCD outcome between three groups of patients depending on their previous spine surgical history at the treated level ( 24 ). Finally, Tian et al reported using PCD after percutaneous lumbar discectomy to treat lumbar disc herniation in two papers ( 25 , 26 ).…”

“…recommended local anaesthesia, what did Tian et al, PCD can be conducted under general anaesthesia as reported by Camino-Willhuber, Kiss and Yamada et al . ( 16 – 18 , 22 , 24 ). For all papers, the volume of injected cement varied between 3–10 mL depending on the patient and spine level, since cement must entirely fill the vacuum.…”

“…The surgery duration varied between papers, depending on the number of treated levels, from about 25 min for one level PCD to more than 1 h for five level PCD. Camino-Willhuber et al demonstrated that PCD associated with decompression surgery in cases with spinal stenosis, also provided promising outcome to treat the patients ( 24 ). Decompression surgery could also be directly indicated from the results of the intraoperative neurophysiological monitoring in case of leakage ( 33 ).…”

“…One deep infection and one fracture of the adjacent vertebral body were later reported by Camino-Willhuber et al along with two cases of leakage in the foramen, one disc extrusion and one unexplained pain ( 22 ). Overall, in their last paper complications were reported to affect 16% patients, with only 5.7% (9/156) requiring a second operation ( 24 ). Cement leakage accounted for 3.2% and vertebral fracture for only 0.6%.…”

“…Among the nine papers including a follow-up, the shortest follow-ups lasted six months ( 9 , 16 ). Camino-Willhuber et al presented a 12 months follow-up ( 22 ) and a second study of 24 months follow-up ( 24 ). Tian et al presented a 12 months follow-up ( 25 ) and a second study with an averaged follow-up of 39 months ( 26 ).…”

Critical Review of the State-of-the-Art on Lumbar Percutaneous Cement Discoplasty

et al. 2022

Interbody fusion is the gold standard surgery to treat lumbar disc degeneration disease but can be a high-risk procedure in elderly and polymorbid patients. Percutaneous Cement Discoplasty (PCD) is a minimally invasive technique developed to treat advanced stage of disc degeneration exhibiting a vacuum phenomenon. A patient-specific stand-alone spacer is created by filling the disc with polymethylmethacrylate cement, allowing to recover the disc height and improve the patient’s conditions. As it has recently been introduced in the lumbar spine, this review aims to present a transversal state-of-the-art of the surgery from its clinical practice and outcome to biomechanical and engineering topics. The literature was searched across multiple databases using predefined keywords over no limited period of time. Papers about vertebroplasty were excluded. Among 466 identified papers, the relevant ones included twelve clinical papers reporting the variations of the surgical technique, follow-up and complications, four papers reporting biomechanical ex vivo and numerical tests, and four letters related to published clinical papers. Papers presenting the operative practice are reported, as well as follow-ups up to four years. The papers found, consistently reported that PCD significantly improved the clinical status of the patients and maintained it after two years. Spine alignment was impacted by PCD: the sacral slope was significantly reduced, and disc height increased. The foramen opening correlated to the volume of injected cement. Substitutes to the acrylic cement exhibited better osteointegration and mechanical properties closer to bone tissue. Finally, limitations and risks of the surgery are discussed as well as potential improvements such as the development of new filling materials with better mechanical properties and biological integration or the investigation of the inner disc.
