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.

The aim of our study is to establish whether the bone graft harvested and stored in the surgical wound by our novel technique is safe, reproducible and preserves the viability of the graft. In doing so, it promises successful bony fusion in spine and orthopaedic surgeries. ⋯ The operative site provides an ideal, safe and reproducible location for bone graft storage for staged surgeries conducted in resource constrained situations. The osteogenic potential of the autogenous bone graft is retained. This technique can be extrapolated to other orthopaedic surgeries conducted under resource limited environments like in surgical camps or combat medical facilities.

Intervertebral disc degeneration (IVDD) considerably impacts global disability and quality of life. Although potential links between plasma proteins and IVDD exist, their causal correlation remains undefined. This study explored the causal links between plasma proteins and IVDD employing genome-wide association study data. ⋯ The study underscores the causal correlation between plasma protein levels and IVDD risk. These identified proteins could emerge as unique biomarkers for IVDD, contributing to its predictive measures. The findings further our understanding of IVDD pathomechanisms and prospective therapeutic targets.

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.
