“…In addition, it is worth mentioning that PEEK has a high transmittance, which enables doctors to more clearly observe the local reactions and tumor recurrence after surgery through CT or MRI, giving it unique advantages over traditional metal implants in the field of bone tumors (such as spinal tumors) [ 154 ].…”

The repair of large-area irregular bone defects is one of the complex problems in orthopedic clinical treatment. The bone repair scaffolds currently studied include electrospun membrane, hydrogel, bone cement, 3D printed bone tissue scaffolds, etc., among which 3D printed polymer-based scaffolds Bone scaffolds are the most promising for clinical applications. This is because 3D printing is modeled based on the im-aging results of actual bone defects so that the printed scaffolds can perfectly fit the bone defect, and the printed components can be adjusted to promote Osteogenesis. This review introduces a variety of 3D printing technologies and bone healing processes, reviews previous studies on the characteristics of commonly used natural or synthetic polymers, and clinical applications of 3D printed bone tissue scaffolds, analyzes and elaborates the characteristics of ideal bone tissue scaffolds, from t he progress of 3D printing bone tissue scaffolds were summarized in many aspects. The challenges and potential prospects in this direction were discussed.

“…For example, lower tensile strength may contribute to failure with compressive and shear forces, implant failure is difficult to assess, and the implant options available remain limited. [13,14] Given the limited data that currently exists pertaining to these radiolucent implants, this study sought to query the perspectives of the specialists in the North American Spine Society (NASS) section of Spinal Oncology with regards to their clinical utility, current practice patterns, and recommended future directions. Given the lack of data in the literature, our a priori hypothesis was that opinions wouldl vary widely even among these specialists.…”

“…However, the current literature on CF and CFR-PEEK radiolucent implants is sparse for both biomechanical and clinical studies, and these implants have their own set of disadvantages. For example, lower tensile strength may contribute to failure with compressive and shear forces, implant failure is difficult to assess, and the implant options available remain limited [ 13 , 14 ].

“…Radiolucency allows earlier detection of postoperative complications and local recurrence, which can significantly impact the patient’s quality of life and future treatment decisions. Carbon fibre/polyetheretherketone (CF/PEEK) is a relatively novel material that offers an ideal balance of radiolucency and biomechanical properties suited for tumour applications [ 2 ]. Reinforcement of polyetheretherketone by carbon fibre increases its rigidity and elastic modulus closer to bone, reducing the risk of hardware failure while avoiding artefact generation on imaging [ 3 ].…”
Clear cell meningioma is an uncommon variant of meningioma associated with high rates of local recurrence and metastasis. However, monitoring for local recurrence may be complicated by metal-related artefacts generated by spinal instrumentation. We present a patient with recurrent lumbar atypical clear cell meningioma, which had been resected multiple times throughout her adolescence. Due to extensive bone and ligament resection, posterior stabilization of the lumbar spine with pedicle screws was required. To ensure clear postoperative visualization of the spinal cord for local recurrence, a carbon fibre/polyetheretherketone (CF/PEEK) pedicle screw and rod construct was used. CF/PEEK has non-inferior biomechanical and biocompatible properties to titanium, with a clear advantage of radiolucency to assist in detecting the local recurrence early and facilitating accurate radiotherapy planning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
