Objective: Imperfect fitting of the navigation template leads to prolonged surgery time and increased blood loss. These problems have not been effectively addressed in previous research. This study explores the efficacy of a novel 5-point positioning point-contact pedicle navigation template in complex pedicle situations in scoliosis.

Objective: To explore the effectiveness of a new point contact pedicle navigation template (referred to as "new navigation template" for simplicity) in assisting screw implantation in scoliosis correction surgery.
Methods: Twenty-five patients with scoliosis, who met the selection criteria between February 2020 and February 2023, were selected as the trial group. During the scoliosis correction surgery, the three-dimensional printed new navigation template was used to assist in screw implantation.
Objective: The loss of neural ability leading to subsequent diminishing of motor function and the impairment below the location of the injury is a result of the SCI (Spinal Cord Injury). Among the many therapeutic agents for SCI, the exosomes considered as extracellular vesicles seem to be the most promising. Sonic Hedgehog (Shh) is an exosome-carrying protein.

Methods: Thirty rats were randomized into the following groups: control, sham, model, mild hypothermia (MH), and mild hypothermia plus rutin (MH+Rutin). We used modified Allen's method to injure the spinal cord (T10) in rats, and then treated it with MH or/and rutin immediately.
Background: Spinal cord injuries (SCIs) can cause a loss of neurons and associated sensory and motor functionality below the injured site. No approaches to treating SCIs in humans have been developed to date. Exosomes are extracellular vesicles that hold promise as a potential therapeutic modality when treating such injuries.

Methods: A clinical data of 28 patients with severe rigid spinal deformity between January 2015 and November 2017 was retrospectively analyzed. Sixteen patients were treated by Halo-pelvic traction with posterior spinal osteotomy (group A) and 12 patients were treated with posterior spinal osteotomy only (group B).
Objectives: To investigate the primary clinical value of atlantoaxial pedicle screw placement assisted by a modified 3D-printed navigation template.
Methods: We retrospectively analyzed the cases of 17 patients treated from June 2015 to September 2016 with atlantoaxial pedicle screw placement assisted by a modified 3D-printed navigation template. All procedures were performed prior to surgery, including thin-slice CT scanning, medical image sampling and computerized 3D modeling of the atlantoaxial joint, optimal pedicle screw trajectory determination, and anatomical trait acquisition for the atlantoaxial pedicle, spinous process of the axis, vertebral lamina and posterior lateral mass, and design of a reverse template.
