[Minimally invasive osteosynthesis in septic conditions]

Area of Science:

• Spinal surgery
• Orthopedic surgery
• Infectious disease management

Background:

• Management of pyogenic spondylodiscitis in adults presents challenges.
• Minimally invasive surgical techniques are increasingly explored for spinal conditions.

Purpose of the Study:

• To evaluate the efficacy of a minimally invasive method for deformity correction and stabilization in pyogenic spondylodiscitis.
• To assess the outcomes of percutaneous osteosynthesis combined with anterior grafting.

Main Methods:

• A two-step surgical procedure was employed: posterior percutaneous osteosynthesis followed by anterior intervertebral grafting.
• Ten adult patients with pyogenic spondylodiscitis were included.
• Clinical and radiological evaluations assessed deformity correction and vertebral body height restoration.

Main Results:

• Successful pain control and bacteriologic identification were achieved in all cases.
• Postoperative radiological assessment showed significant correction of sagittal deformity (mean -8.4°) and restoration of vertebral body height (mean 8mm).
• Solid bony fusion was observed in most patients at the last follow-up, with minimal loss of correction.

Conclusions:

• Percutaneous osteosynthesis with anterior grafting is a safe and effective treatment for pyogenic spondylodiscitis.
• This minimally invasive approach offers satisfactory clinical and radiographic outcomes.
• It represents a viable alternative for spinal stabilization and deformity correction, particularly in patients with comorbidities.
