Comparison of internal fixation with hollow two-way compression screw and double Kirschner pin for the treatment of Jones fracture:

摘要

Category:Midfoot/ForefootIntroduction/Purpose:To compare the clinical effect of hollow bidirectional compression screw and double Kirschner needle in the treatment of Jones fracture.Methods:32 cases of Jones fractures treated follow-up were analyzed retrospectively, including 20 cases of application of hollow biaxial compression intramedullary screw fixation for 12 cases, double Kirschner wire internal fixation.Results:all 32 cases were followed up for 6~18 months, with an average of 10 months. For two-way hollow compression screw nail 20 cases, including 19 cases healed, 1 cases of delayed healing, the healing rate was 95%, the average healing time of 11.2 weeks (9 - 13). 12 cases of internal fixation with double Kirschner needle were performed, of which 8 cases were bone healing, 3 cases were delayed union, 1 cases were not healed, the healing rate was 75%, the average healing time was 14.7 (12~16) weeks. The average healing time after two groups of internal fixation was statistically analyzed, and the ...
