C1-C2 Goel-Harms Fixation, History of the Technique, Free Hand Technique Description

摘要

Objective: Short historical description of the evolution of C1-C2 fixation methods, anatomical tricks and free hand fixation technique description. Method: five patients were operated on using free hand technique, X-rays were only used after the positioning of the patient in the ventral position with Mayfield and at the end before locking the lateral rods. Results: no complications documented, in all the cases CT scans revealed good screw position. Conclusion: Using these landmarks and with a good preoperative planning, it is easy for experienced surgeons to perform the technique in a free hand manner, that avoids X-ray exposure for the whole team and the patient. This technique is not recommended for common use, especially for surgeons with few experiences in this field.
