Surgery of the craniocervical junction (CCJ) and clivus is technically demanding. For many years, we have used the submandibular retropharyngeal approach for surgery of the upper cervical spine, especially hangman fracture. We hypothesized that submandibular gland resection could offer a significant cranial enlargement of the operative field, up to the clivus. Our aim in this work was to assess the feasibility of an endoscope-assisted retropharyngeal approach to the CCJ and clivus. ⋯ An endoscopic submandibular retropharyngeal approach provides a simple and straightforward access to the CCJ. It also conveniently exposes the clivus. This technique could be added to the techniques used for this difficult surgery.

Bone cement augmentation procedures (vertebroplasty and kyphoplasty) are the primary treatments for osteoporotic vertebral compression fracture (VCF). However, these procedures are associated with various problems resulting in subsequent fracture. The purpose of this study was to evaluate the spinal instability factors related to subsequent fracture after vertebral augmentation procedures. ⋯ Predictive scores can be calculated and used to predict the possibility of subsequent fracture according to scores. Group D showed the highest predictive scores and will need more preventative treatment.

To evaluate the efficacy of biocomposite screws used in ovariectomy (OVX)-induced osteoporotic rats. ⋯ Biocomposite screws can improve local bone quality and facilitate osteoconductivity in an osteoporotic rat model.

Postoperative neurologic outcomes after primary somatosensory cortex (S1) resection have not been well documented. This study was designed to evaluate the neurologic deterioration that follows resection of the S1 areas and to assess the risk factors associated with these morbidities. ⋯ The neurologic risk of the resection of S1 and/or its adjacent cortical areas was 40%. The additional resection of the PPC was significantly associated with the development of postoperative neurologic impairments.

We sought to evaluate long-term results of surgical treatment of thoracolumbar segmental spinal dysgenesis (SSD). ⋯ Our treatment strategy provides favorable deformity correction and neurologic improvement. It is limited by immature vertebral structures in newborns and infants, who should be carefully monitored from birth with braces until they reach the age when a fixing tool can be used.
