ABSTRACT
This article describes the complications after medial opening wedge high tibial osteotomy
(HTO) with the TomoFix plate. Between June 2003 and July 2005, 40 TomoFix medial opening
wedge HTOs were performed. On average, radiological consolidation was reached after
10.4 months. Nonunions were not recorded. In 4 cases (10%), a superficial infection
was found. Between operation and consolidation of the osteotomy, an average loss of
correction of 0.3° was observed. Loss of correction after removal of the implant was
not observed. Excluding the breakage of 1 screw during extraction of the implant,
failure did not occur. The fixation of the TomoFix with locking-head screws for the
opening wedge HTO, as described in this study, is stable. The planned correction could
be reached with high exactitude during the operation.
