Abstract:
Purpose:This paper reports the clinical and radiological outcomes of a combined fixation method using K-wire fixation and static external fixation in pilon fractures of the proximal interphalangeal joint (PIPJ).
Materials and Methods:From March 2022 to February 2024, patients treated at a single institution for pilon fractures of the proximal phalanx using K-wire fixation and static external fixation were investigated. Patients who were followed up for more than 4 months were selected. The exclusion criteria were those with previous fractures or surgeries in the same area, vascular or nerve injuries, or underlying conditions such as rheumatoid arthritis were excluded. Six patients were included in the study. Clinical evaluations included assessments of the range of motion (ROM) of the PIPJ and pain scores using the visual analogue scale (VAS). Radiological evaluations assessed the congruity of the joint and joint space. Postoperative complications were also investigated.
Results:At the final follow-up, the mean ROM of the PIPJ, extension lag, and VAS pain score were 94° (flexion range: 80°–110°), the mean extension lag was 5.0° (extension range: 0°–10°), and 0.7, repectively. The radiographs confirmed the proper congruity of the joint and joint space. One patient developed stiffness in the distal interphalangeal joint with a ROM of 35° (-20° to 55°), but no functional issues with the hand were noted. No complications such as infections or complex regional pain syndrome, were encountered, and no patients required additional surgery.
Conclusion:The combined fixation method using K-wire fixation and static external fixation appears to be an effective and safe surgical method for treating pilon fractures of the PIPJ.
