One of the major advantages of a minimally invasive microdiscectomy is that when CSF leak occurs, there is minimal anatomic dead space for ongoing leakage following removal of the tubular retractor. However, there are no published reports that address the safety and long-term outcomes of same-day discharge for CSF leak after tubular microdiscectomy. ⋯ Patients with CSF leak during minimally invasive tubular microdiscectomy can be safely discharged home the same day.

Short-term efficacy of percutaneous kyphoplasty (PKP) for treating osteoporotic vertebral compression fracture (OVCF) in elderly patients is good, but long-term complications such as vertebral recompression (VRC) and adjacent vertebral fracture (AVF) may arise. Identifying risk factors in patients with poor prognoses, we developed a nomogram model to mitigate these potential complications. ⋯ This study identified four independent predictors of poor prognosis following PKP and devised a straightforward yet efficient predictive model. This model offers valuable insights for guiding clinical decision-making in the management of elderly patients with OVCFs.

In patients with traumatic, infectious, degenerative, and neoplastic surgical indications in the cervical spine, commonly the anterior approach is used. Often these patients require a tracheostomy necessary due to prolonged mechanical ventilation. The limited spinal mobility and proximity to the surgical site of anterior cervical spine fixation (ACSF) could pose an increased risk for complications of percutaneous dilational tracheostomy (PDT.) Importantly, PDT might raise wound infection rates of the cervical spine approach. The aim of this study is to prove safety of PDT after ACSF. ⋯ PDT is a feasible and safe procedure in patients after ACSF. Complication rates are comparable to patients without ACSF. Surgical site infections of ACSF are very rare.

To compare the mechanical properties of human annulus fibrosus obtained by forceps versus bistoury and observe whether the measurement could be affected by forceps sampling method. ⋯ The results indicate that the forceps sampling method has a substantial negative effect on the micromechanical properties of the ECM of the annulus fibrosus. Bistoury sampling method is recommended as the experimental subject for exploring the micromechanics mechanisms of cervical degenerative disease.
