Cervical total disc arthroplasty (TDA) is a motion-preserving alternative to anterior cervical discectomy and fusion that has gained popularity among spine surgeons. Although generally effective, TDA has been associated with rare cases of progressive osteolysis, a complication whose natural history and impact on clinical outcomes are not well understood. This case report aims to present a case of progressive osteolysis following cervical TDA with the SpinalKinetics® M6-C Artificial Cervical Disc and to discuss the clinical approach and implications for patient management. ⋯ This case highlights the potential for progressive osteolysis as a complication following cervical TDA, emphasizing the importance of ongoing surveillance and increased awareness among spine surgeons. Early identification and monitoring of osteolysis may mitigate the risk of severe outcomes and guide timely intervention.

As the number of instrumented fusions increases, so does the utilization of bone substitutes. However, controversies persist regarding the effectiveness of ceramics in promoting solid fusion. Few histological studies have been conducted on patients to address this issue. To contribute insights into this topic, we assessed bony fusion both intraoperatively and histologically in patients who underwent posterolateral instrumented fusions enhanced with a biphasic ceramic compound. ⋯ The utilization of biphasic ceramics proved ineffective in attaining a proper fusion mass between the intertransverse space. Both surgical inspection and histological studies confirmed the absence of integration. Prudence should be exercised regarding the use of ceramics. While no clear instability was observed, neither was there any integration.

To compare the clinical efficacy of unilateral biportal endoscopy technology (UBE) with anterior cervical discectomy and fusion(ACDF)for the treatment of single-segment cervical spondylotic radiculopathy (CSR). ⋯ UBE can effectively treat patients with single-segment CRS and promote rapid recovery.

To investigate the impact of the Global Alignment and Proportion (GAP) score components on patient outcomes in Adult Spine Deformity (ASD) surgery. ⋯ The spinopelvic component of the GAP score is the most significant independent predictor of clinical outcomes. Its interaction with the other components of the GAP score also aids assessment of the risk for mechanical complications.

This study aimed to explore associations between ABO blood type and postoperative adjacent segment degeneration/disease (ASD) following lumbar spine fusion, as well as evaluate differences in spinopelvic alignment, perioperative care, postoperative complications, and patient-reported outcome measures (PROMs). ⋯ This is the first large-scale study to address and demonstrate proof-of-principle that ABO blood type, a non-modifiable risk factor, is associated with ASD following lumbar spine fusion.
