Abstract

BackgroundReconstruction of Charcot feet remains a surgical challenge. The goal of this study was to investigate safety and clinical benefit from reconstruction of Charcot feet using an external fixator. There is limited valid data regarding long-term outcomes for Charcot foot procedures.

MethodsIn a retrospective study, 292 Charcot feet 282 patients undergoing reconstructive procedures in our clinic from 1996–2010 were included 93 female, 189 male, mean age 57.9 years. Average follow-up was 24.1 months. Exclusion criteria were previous major amputation on the same side. All patients underwent surgery using a Hoffmann II external fixator for six to eight weeks with offloading. The fixator was then removed, and a customized AFO with full weight bearing was applied for another 11 months. After one year, patients received customized orthopedic shoes.

ResultsInitial amputations were avoided. Patient activity improved significantly by more than 1 level SD 0.67, p < .001 according to the Hoffer activity score for lower limb amputees. The most common minor complication was persistent or recurrent ulceration in 67 feet 23%. Secondary amputation after failure of external fixation was required in only 12 patients 6.2%. Orthopedic shoes were used by approximately 34% of patients 18 months after surgery.

ConclusionsReconstructive surgery of Charcot feet using external fixation is a safe and economically feasible procedure. Activity levels improved significantly by more than 1 level p < 0.01, severe complications were rare, and secondary amputation was required in only 12 patients 6.2% of a high-risk patient population. Use of an external fixator offers the advantage that all extraneous material is removed after six weeks; thus, there is no risk of broken screws or plates and the associated potential complications.
