Purpose
To assess the use of a 2-mm miniplate as a dorsal blocking plate to stabilize the
central avulsion fragment in a proximal interphalangeal joint (PIP) volar fracture
dislocation.
Methods
This was a case series comprising 8 patients with volar fracture dislocation of the
PIP joint. The average age of the patients was 36 years. The patients were managed
by this technique within an average of 11 days following the injury. The clinical
outcome measurements included the assessment of pain and range of motion of the PIP
and distal interphalangeal joints.
Results
The average follow-up duration was 20 months. The mean visual analog scale pain score
was 1.9. The average range of motion of the PIP joint was 82°, whereas the average
range of motion of the distal interphalangeal joint was 43°. Reduction of the subluxation
was achieved in all cases, with no articular step remaining.
Conclusions
A dorsal blocking plate is a simple technique, associated with a satisfactory outcome,
for volar fracture dislocation injuries of the PIP joint.
Type of study/level of evidence
