Summary
A modified dynamic fixator effectively treats proximal interphalangeal (PIP) joint fracture dislocations. This technique enhances stability, restores digital range of motion, and offers satisfactory functional results for PIP joint injuries.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Traumatology
Background:
- Proximal interphalangeal (PIP) joint fracture dislocations present treatment challenges.
- Existing skeletal traction devices are often complex or cumbersome.
- A need exists for simpler, more stable fixation methods.
Purpose of the Study:
- To present a modified dynamic fixation system for PIP joint fracture dislocations.
- To evaluate the stability and functional outcomes of this enhanced technique.
- To report results from patients treated with this modified fixator.
Main Methods:
- A modified dynamic fixator, without rubber bands, was applied to 6 patients with PIP joint fracture dislocations.
- The fixator allowed immediate active flexion and extension.
- Patients were followed for an average of 24 months, with fixator removal after 3-4 weeks.
Main Results:
- The average range of motion achieved was 5 to 89 degrees (0-100 degrees).
- Two patients experienced minor pin track infections, successfully treated with antibiotics.
- Radiographs confirmed proper joint reduction and congruency post-treatment.
Conclusions:
- The modified dynamic fixator successfully treated unstable PIP joint fracture dislocations in 6 digits.
- The design modifications improved construct stability and yielded satisfactory functional outcomes.
- This technique is recommended for its ease of use and effectiveness in treating PIP joint fracture dislocations.
