Static external fixator and concomittant K-wire fixation for pilon type fracture of the proximal interphalangeal joint of the finger
Abstract
Hypothesis: Fracture-dislocation and pilon injuries of the Proximal Interphalangeal Joints (PIPJ) continue to pose signifcant management challenges. In this study, we report clinical and radiographic outcomes of a pilon type fracture-dislocation of the proximal interphalangeal joint of the finger using static external fixator and concomittant K-wire fixations.
Methods: Static external fixator and K-wire fixations were applied for 6 pilon type PIPJ fractures. The joints involved were 3rd PIPJ in 1 patient, 4th PIPJ in 3 patients, and 5th PIPJ in 2 patients. The mean age of the patients was 41.7 (range, 27 ~ 52) and mean follow-up udration was 7.7 months (range, 4 - 12 months). All patients were clinically and radiologically assessed on an outpatient basis after being discharged.
Results: At the final follow-up, the mean range of motion of PIP joints in flexion was 99.5° (flexion range, 85°–110°), the mean extension lag was 5.0° (extension range, 0°–15°), and the mean visual analogue scale score was 0.7. On anteriorposterior and lateral radiographs, congruity of the joint was satisfactory and distal interphalangeal joint stiffness was found in one cases.
Summary: We attained satisfactory clinical outcomes on the recovery of joint movement and joint congruity after treating PIP joint fracture-dislocation injury with multiple K-wire fixation using static external fixator.
