Clinical efficacy analysis of three kinds of surgical treatment for bony mallet fingers

Abstract

Objective To compare the clinical outcomes of three kinds of surgical treatment for bony mallet fingers, and to explore the appropriate treatment method. Methods From March 2010 to March 2013, 92 cases of bony mallet fingers were treated with Ishiguro method (32 cases), Kirschner wire combined steel wire cross compression (34 cases), reconstruction of extensor tendon insertion with miniature anchor (26 cases) respectively. Results All the patients were follow-up for 4 to 20 months with an average of 9.6 months. According to Patel mallet finger evaluation standard, the results of Ishiguro method group were excellent in 15 cases, good in 12 cases, fair in 4 cases and poor in 1 case, with the excellent and good rate being 84.4%. The results of Kirschner wire combined steel wire cross compression group were excellent in 11 cases, good in 18 cases, fair in 3 cases and poor in 2 cases, with the excellent and good rate being 85.3%. The results of reconstruction of extensor tendon insertion with miniature anchor group were excellent in 10 cases, good in 12 cases, fair in 3 cases and poor in 1 case, with the excellent and good rate being 84.6%. Conclusion There were no significant differences in the clinical efficacy of the three surgical methods for bony mallet fingers. Considering the fracture classification of the mallet fingers, the proficiency of the doctors and the economic ability of the patients, reasonable selection of suitable operation method is the key to the successful treatment of bony mallet fingers.
