Conventional percutaneous vertebroplasty (PVP) are mainly guided by C-arm fluoroscopy, and it usually leads to excessive X-ray radiation exposure to patients, surgeons, and anesthetists. Moreover, multi-time fluoroscope may prolong the operation time. 3D-printed template could help minimize fluoroscopy shot times and fluoroscopy dosage during operation, and shorten operation time. This study was performed to compare the efficacy and accuracy of PVP assisted by “three-dimensional printed individual guide template” versus conventional PVP.

At a 1:1 ratio, patients who needed operative care for an acute painful single segment osteoporotic vertebral compression fracture (OVCF) were randomly assigned to one of two groups: three-dimensional printing individual guide template-assisted percutaneous vertebroplasty (group A) or traditional PVP led by C-arm fluoroscopy (group B).

The key assessment criteria for the two activity procedures were fluoroscopy times for puncture points (FTPP), total radiation dosages (TRD), total fluoroscopy period (TFT), and total operation time (TOT).

--A total of 36 acute painful single segment OVCF patients were successfully operated on, and each group has 18 patients. None of the patients presented symptomatic complications.

--The surgical success rate in group A was 94.4%, one patient in the group A was failed and then operated by conventional procedure.

--FTPP (1.8 ± 0.8 in group A vs 5.2 ± 1.9 in group B), TRD (4.9 ± 0.9 mGy vs 7.9 ± 1.6 mGy), TFT (16.7 ± 2.9 vs 26.6 ± 5.3), and total operation time (19.4 ± 2.4 min vs 27.8 ± 4.0 min) were presented statistically difference in the two groups.

--The incidence of cement leakage occurred in group A (3/18, 16.7%) was less than that occurred in group B (7/18, 38.9%).

To summarize, “three-dimensional-printed individual guide template-assisted PVP” could reduce fluoroscopy shot times and fluoroscopy dose during service, shorten operation time, and is a more accurate and feasible operation method than traditional PVP.
