Abstract: Objective To discuss the curative effect of cannulated compression screws in treating the fresh scaphoid fracture without displacement,and to clarify the advantages of palmar miniature incision in treatment of fresh scaphoid fractures without displacement. Methods 14 patients with fresh scaphoid fracturewithout displacement were treated with AO　3.0 mm  cannulated compression screws internal fixation.The average age of the patients was 32 years old.The patients were classified by Krimmer pattern into 2 types: 6 patients were A1 type and the other 8 patients were A2 type.All the patients underwent internal fixation with the palmar miniature incision procedure.The fracture healing situation was observed by postoperation reexamination of X-rays.The wrist joints recovery and functional status were evaluated by Krimmer score standard.Results the average follow-up time was 12 months.14 patients with scaphoid fracture were cured with favorable function,11 got the best function,2 got the better,and 1 got good.The range of motion of the wrist was 50°-165° with an average of (120±25)°.The cubit radial deviation was 28°-81° with an average of (61.0±10.4)°.The grip strength was 20-65 kg with an average of (50.0±6.7) kg.Conclusion Cannulated compression screws by the palmar miniature incision procedure has got a good effect in treatment of fresh scaphoid fracture without displacement.
