The purpose of this retrospective study was to report on percutaneous reduction and
fixation for the treatment of fractures of metatarsal shaft. Between March 2015 and
October 2017, 29 patients (37 fractures of metatarsal shaft) were treated using a
cemented Kirschner wire (K-wire) frame. The accuracy of reduction of the fragments
was assessed as anatomic (0 to 8 points), good (9 to 11 points), fair (12 to 15 points),
or poor (>15 points). The Maryland foot score was used to assess pain and functional
outcomes. All fractures were reduced using percutaneous techniques. Anatomic reduction
was achieved in 31 metatarsal fractures (84%), and good reduction was achieved in
6 (16%). The average bone healing time was 7 weeks (range, 4 to 16). Pin tract infection
was noted in 2 metatarsal bones, which healed with pin site care. The mean cost of
the cemented K-wire frame was US$335 (range, $283 to $385) per patient. Based on the
Maryland foot score, there were 26 excellent results (90%) and 3 good results (10%).
The cemented K-wire frame is a useful external fixator and can be an alternative for
treating fractures of metatarsal shaft, especially when open surgeries are a major
concern owing to severely damaged soft-tissue envelope. The system is cheap and easy
to apply and provides rigid fixation, resulting in good function of the foot.
