Description
Niu leads a team comparing 3D-printed guides with free-hand surgery for upper cervical spine screws, in a 2026 paper. Screw placement in this part of the spine must be exact. A guide made for each patient could help.
Records covered patients treated over many years, split into guide and free-hand groups. The guide group had a higher rate of perfect screw placement and fewer serious breaches of the bone wall. Surgery time, blood loss, and X-ray use were all lower with guides. Both groups improved on pain and function scores, with no gap at final follow-up. The authors call the guides a safe and effective option.
