OBJECTIVE: To investigate the value of the application of a homemade minimally invasive percutaneous percutaneous arch nail rod fixation system. METHODS: Thirty cases of thoracolumbar fractures and degenerative disorders of the lumbar spine were treated with the self-developed arch nail and connecting rod specifically designed for percutaneous puncture placement and a set of surgical tools designed for accurate percutaneous placement of the nail rod, and the system was evaluated in terms of reducing operative time, incision length, intraoperative bleeding and postoperative drainage, use of postoperative analgesics, and intraoperative and postoperative complications by comparing with open surgery. surgical trauma, improve surgical results, and reduce complications. RESULTS: There were no significant differences in operative time and nail placement accuracy between the minimally invasive percutaneous percutaneous root nail fixation systems, and significant differences in surgical incision, intraoperative bleeding and postoperative drainage, and use of analgesic medications. CONCLUSION: The minimally invasive percutaneous percutaneous arch nail fixation system is reasonably designed, simple to place the nail and stick, and highly accurate, which can significantly reduce surgical trauma and improve surgical outcomes.
