Summary
Anterior odontoid screw fixation is a common treatment for axis fractures. A rare complication of screw dislocation causing axis body fracture highlights potential risks of this procedure.
Area of Science:
- Orthopedic Surgery
- Neurosurgery
- Spinal Fusion
Background:
- Anterior odontoid screw fixation is increasingly used for Type II and III odontoid fractures.
- This technique preserves C1-2 motion, making it a preferred surgical option.
- Postoperative immobilization typically involves a cervical collar.
Observation:
- A rare complication occurred 5 weeks after anterior odontoid screw osteosynthesis.
- The patient developed a fracture of the anterior body of the axis.
- This was secondary to screw dislocation following the initial surgery.
Findings:
- The study presents a case of axis body fracture due to anterior odontoid screw dislocation.
- This complication occurred 5 weeks post-osteosynthesis.
- The exact reasons for this rare event are explored.
Implications:
- This case highlights a potential risk associated with anterior odontoid screw fixation.
- Understanding the causes of screw dislocation is crucial for surgical technique refinement.
- Further investigation may be needed to optimize patient selection and postoperative management.
