  • EFFECTIVENESS OF MODIFIED Ishiguro TECHNIQUE WITH STRENGTHENING PRESSURE IN TREATMENT OF BONY MALLET FINGERS

    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). Conclusion 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.

  • Treatment of Wehbe-Schneider typesⅠB and ⅡB bony mallet fingers with one-stage closed reduction and elastic compression fixation with double Kirschner wires

    Objective To investigate the effectiveness of one-stage closed reduction and elastic compression fixation with double Kirschner wires for Wehbe-Schneider types ⅠB and ⅡB bony mallet fingers. Methods Between May 2017 and June 2020, 21 patients with Wehbe-Schneider type ⅠB and ⅡB bony mallet fingers were treated with one-stage closed reduction and elastic compression fixation using double Kirschner wires. There were 15 males and 6 females with an average age of 39.2 years (range, 19-62 years). The causes of injury were sports injury in 9 cases, puncture injury in 7 cases, and sprain in 5 cases. The time from injury to admission was 5-72 hours (mean, 21.0 hours). There were 2 cases of index finger injury, 8 cases of middle finger injury, 9 cases of ring finger injury, and 2 cases of little finger injury. The angle of active dorsiflexion loss of distal interphalangeal joint (DIPJ) was (40.04±4.02)°. According to the Wehbe-Schneider classification standard, there were 10 cases of typeⅠB and 11 cases of type ⅡB. The Kirschner wire was removed at 6 weeks after operation when X-ray film reexamination showed bony union of the avulsion fracture, and the functional exercise of the affected finger was started. Results The operation time was 35-55 minutes (mean, 43.9 minutes). The length of hospital stay was 2-5 days (mean, 3.4 days). No postoperative complications occurred. All patients were followed up 6-12 months (mean, 8.8 months). X-ray films reexamination showed that all avulsion fractures achieved bony union after 4-6 weeks (mean, 5.3 weeks). Kirschner wire was removed at 6 weeks after operation. After Kirschner removal, the visual analogue scale (VAS) score of pain during active flexion of the DIPJ was 1-3 (mean, 1.6); the VAS score of pain was 2-5 (mean, 3.1) when the DIPJ was passively flexed to the maximum range of motion. The angle of active dorsiflexion loss of affected finger was (2.14±2.54)°, showing significant difference when compared with preoperative angle (t=52.186, P<0.001). There was no significant difference in the active flexion angle between the affected finger (79.52±6.31)° and the corresponding healthy finger (81.90±5.36)° (t=1.319, P=0.195). At 6 months after operation, according to Crawford functional evaluation criteria, the effectiveness was rated as excellent in 11 cases, good in 9, and fair in 1, with an excellent and good rate of 95.24%. Conclusion For Wehbe-Schneider typesⅠB and ⅡB bony mallet fingers, one-stage closed reduction and elastic compression fixation with double Kirschner wires can effectively correct the deformity and has the advantages of simple surgery, no incision, and no influence on the appearance of the affected finger.

  • Effectiveness comparison of open reduction and hook plate fixation versus closed indirect reduction and dorsal extension blocking Kirschner wire fixation for bony mallet finger

    Objective To compare the effectiveness of open reduction and hook plate fixation versus closed indirect reduction and dorsal extension blocking Kirschner wire fixation for bony mallet fingers. Methods The clinical data of 68 patients with bony mallet finger who admitted between May 2019 and June 2022 were retrospectively analyzed. Among them, 33 cases were in the open group (treated with open reduction and hook plate fixation) and 35 cases were in the closed group (treated with closed indirect reduction and dorsal extension blocking Kirschner wire fixation). There was no significant difference between the two groups in terms of gender, age, the affected side, the affected finger, cause of injury, time from injury to operation, and Wehbé-Schneider classification (P>0.05). The operation time, intraoperative fluoroscopy frequency, fracture healing time, time of returning to work, and postoperative complications were recorded and compared between the two groups. At 12 months after operation, visual analogue scale (VAS) score was used to assess the pain of the injured finger, active flexion range of motion and extension deficit of the distal interphalangeal joint (DIP) were measured by goniometer, and the effectiveness was assessed by Crawford criteria. Results All patients in the two groups were followed up 12-26 months, with an average of 15 months. There was no significant difference in the follow-up time between the closed group and the open group (P>0.05). The operation time in the closed group was shorter than that in the open group, and the intraoperative fluoroscopy times, the fracture healing time, and the time of returning to work in the closed group were more than those in the open group, and the differences were significant (P<0.05). In the closed group, there were 5 cases of pinning tract infection and 3 cases of small area pressure ulcer skin necrosis on the dorsal side of the finger, which were cured after intensive nursing and dressing change. Local nail depression deformity occurred in 7 cases in the open group, and the deformity disappeared after removal of plate. The incisions of the other patients healed uneventfully without complications such as infection, skin necrosis, exposure of the internal fixation, or nail deformity. There was no significant difference in the incidence of skin necrosis between the two groups (P>0.05), but the differences in the incidence of infection and nail deformity between the two groups were significant (P<0.05). There was no significant difference in VAS score, DIP active flexion range of motion, DIP extension deficiency, or Crawford criteria evaluation between the two groups at 12 months after operation (P>0.05). At last follow-up, there was no DIP osteoarthritis and joint degeneration in both groups. Conclusion Open reduction and hook plate fixation versus closed indirect reduction and dorsal extension blocking Kirschner wire fixation have their own advantages and disadvantages, but both of them have good results in the treatment of bony mallet fingers. Open reduction and hook plate fixation is recommended for young patients with bony mallet fingers who are eager to return to work.
