Abstrakt:	Objective: To investigate the effectiveness of modified Ishiguro technique with strengthening pressure in the treatment of bony mallet finger by comparing with the traditional Ishiguro technique. Methods: Between May 2013 and May 2015, 31 cases of bony mallet finger were treated with traditional Ishiguro technique in 16 cases (control group) and with modified Ishiguro technique in 15 cases (improved group, the two Kirschner wires were bound, which were used to fix the distal interphalangeal joint and blocking avulsion fracture block in the classical Ishiguro technique, and play a continuous elastic compression). Difference was not significant in gender, age, cause of injury, injury finger, and the time from injury to operation between 2 groups ( P > 0.05). Results: The wound healing was delayed in 2 cases of the control group and 1 case of the improved group, and the other patients obtained healing by first intension. The follow-up time was 8-23 months (mean, 11 months) in the improved group and was 9-24 months (mean, 12 months) in the control group. Bending deformation of the Kirschner wire occurred in 2 cases of the control group, obvious separation was found between fracture fragment and the distal phalanx; after manual reduction, brace was used to fix, and distal interphalangeal arthritis occurred during follow-up. The fracture healing time was (6.8±0.8) weeks in the control group, and was (5.7±1.5) weeks in the improved group. There was significant difference in the healing time between 2 groups ( t =-2.439, P =0.021). At last follow-up, according to Crawford criteria, the results were excellent in 9 cases, good in 4 cases, fair in 2 cases, and poor in 1 case with an excellent and good rate of 81.25% in the control group; the results were excellent in 10 cases, good in 3 cases, and fair in 2 case with an excellent and good rate of 86.67% in the improved group. There was no significant difference in excellent and good rate between 2 groups ( Z =-0.636, P =0.525). Conclusions: Compared with traditional Ishiguro technique, the modified Ishiguro technique with strengthening pressure in treatment of bony mallet finger can facilitate the fracture healing, reduce Kirschner wire loosening and deformation, and decrease the rates of operation failure and complications.
