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.

Numerous studies have reported that corrective surgery improves postoperative health-related quality of life (HRQOL) in patients with adult spinal deformity (ASD), and postoperative HRQOL is maintained over 5-year follow-up. However, few studies have investigated factors associated with mid-term patient satisfaction. This study aimed to examine the factors contributing to 5-year patient satisfaction in patients with ASD following corrective surgery. ⋯ These findings underscore the significance of functional and social function improvements following corrective surgery, as they contribute to higher levels of satisfaction among patients with ASD.

To present two cases of life-threatening hemorrhage related to lumbar artery injury in adult spinal deformity (ASD) patients following S2‑alar‑iliac (S2AI) fixation and asymmetrical pedicle subtraction osteotomy (PSO), and discuss the possible reasons for postoperative hemorrhage in these patients. ⋯ For patients with severe kyphoscoliosis, asymmetrical PSO increases the risk of lumbar artery injury on the convex side, and postoperative ST may further contribute to this risk. In cases where a sudden increase in drainage is observed postoperatively, it is crucial to consider the possibility of lumbar artery injury, particularly on the convex side of the osteotomized vertebra.

Observational Study
The change in lumbar lordosis from the standing to the lateral position: implications for lateral interbody fusion.
The purpose of this cross-sectional, observational study was to establish the relationship between standing lumbar lordosis (LL) and lateral decubitus LL. ⋯ Standing LL was strongly correlated to lateral decubitus LL, although subjects lost an average of 11.9° from the standing to the lateral decubitus position. This has important implications for fusion in the lateral position.

The endocannabinoid system (ECS) has been well-established to play a crucial role in the regulation of several physiological processes as well as many inflammatory disease conditions. However, its role in intervertebral disc degeneration has been least explored. We aim to investigate the immunomodulatory role of endocannabinoids in regulating IVD health. ⋯ Diagnostic: individual cross-sectional studies with consistently applied reference standard and blinding.
