				        	Objective To introduce the method of using hollow pull screw insertion for the suprapubic fracture with 3D printing navigation template and to evaluate its clinical effect.Methods From March 2016 to August 2017,eighteen cases of suprapubic ramus fractures treated with hollow lag screw fixation in the Department of Orthopedics of Yanan University Affiliated Hospital were retrospectively collected was collected.Before operation,the thin slice CT scan of pelvis was used to get raw data,and the mimics17.0 software was used to reconstruction the model,to design and make the personalized navigation template assisting the suprapubic fractures surgery.The navigation template was printed out pre-operatively,and the nail was inserted via the assisted by the template intra-operatively.After the operation,the fracture reduction was evaluated by Matta imaging scores and the pelvis function was evaluated by Majeed scores.Results All the operations were successfully completed.The Matta scores were excellent in 11 cases,good in 6 cases,and fair in 1 case.The Majeed scores were excellent in 13 cases,good in 3 cases,and fair in 2 cases.Conclusion 3D Printing navigation template assisted the placement of the hollow screw on the suprapubic fracture could provide personalized treatment,reduce the difficulty of operation and satisfy the clinical effect.
