Background:
One goal in the operative treatment of displaced calcaneal frac-
tures is to restore the anatomy of the posterior facet. Conventional fluoroscopes
are unable to viaualise the posterior facet.
Purpose / Aim of Study:
We used intraoperative CT-scans for 3D- imaging
to aid the reduction af fixation of calcaneal fractures and report our results and
experiences
Materials and Methods:
62 non-consecutive patients received open reduc-
tion and internal plate fixation of displaced calcaneal fractures that were aided
by intraoperative CT-scans for 3D imaging.
Findings / Results:
The postoperative articular dislocation was 0 mm in 69%
of the Sanders type 2 fractures and 57% of hte Sanders type 3 fractures. In
40% of the operations, the intraoperative scan visualised articular steps, screws
penetrating joints or being to long, with the possibility of revision before wound
closure.
Conclusions:
Intraoperative CT-scanning in calcaneal fracture surgery facili-
tates the reduction and correct placement of plate and screws, leads to good
operative results, and obviates the risk for reoperations. Scanning prolongs the
operative procedure, but does not increase the infection rate.
