Abstract

PURPOSE
This paper suggests the use of distraction dynamic external fixators (DDEF) for the treatment of proximal middle phalanx fractures.
MATERIALS AND METHODS
Seven patients, who were diagnosed with comminuted intra-articular fractures at the base of the middle phalanx from February 2014 to November 2016, were enrolled in this study (volar aspect 6 cases, dorsal aspect 1 case). They underwent a closed reduction under a C-arm image intensifier, and DDEF was applied with general anesthesia. Range of motion (ROM) exercise was encouraged after 3 to 5 days postoperatively, and DDEF was removed after 5 weeks. Subluxation, angulation and displacement were evaluated 6 weeks postoperatively.
RESULTS
The patients who were treated with DDEF showed a normal proximal interphalangeal joint ROM (100°), and there was no subluxation or displacement on the X-ray film 6 weeks postoperatively. In addition, there were no signs of infection, such as local heat, redness, and pus-like discharge.
CONCLUSION
DDEF helps maintain the reduction and reducing forces through the ligamentotaxis. The joint stiffness is reduced, which it makes early return to daily life easier.

Abstract

Purpose

This paper suggests the use of distraction dynamic external fixators (DDEF) for the treatment of proximal middle phalanx fractures.

Materials and Methods

Seven patients, who were diagnosed with comminuted intra-articular fractures at the base of the middle phalanx from February 2014 to November 2016, were enrolled in this study (volar aspect 6 cases, dorsal aspect 1 case). They underwent a closed reduction under a C-arm image intensifier, and DDEF was applied with general anesthesia. Range of motion (ROM) exercise was encouraged after 3 to 5 days postoperatively, and DDEF was removed after 5 weeks. Subluxation, angulation and displacement were evaluated 6 weeks postoperatively.

Results

The patients who were treated with DDEF showed a normal proximal interphalangeal joint ROM (100°), and there was no subluxation or displacement on the X-ray film 6 weeks postoperatively. In addition, there were no signs of infection, such as local heat, redness, and pus-like discharge.

Conclusion

DDEF helps maintain the reduction and reducing forces through the ligamentotaxis. The joint stiffness is reduced, which it makes early return to daily life easier.
