| Sumario: | Introduction: Equinovarus foot deformity is a significant
problem in adolescents and its treatment remains challenging.
Triple arthrodesis, even though an effective palliative tool in
management of complex foot deformity, has its own limitations if
it is done for acute deformity correction. Ilizarov technique offers
gradual deformity correction, fusion and takes care of many
known complications of acute correction. However, there are
very few studies about effectiveness and functional outcome of
triple arthrodesis for equinovarus deformity when done gradually
with an Ilizarov fixator.
Aim: To study the effectiveness of triple arthrodesis, performed with
Ilizarov technique for equinovarus foot deformity in adolescents
and adults and to evaluate the early functional outcome and
patient satisfaction rate for this procedure.
Materials and Methods: A retrospective analysis of 22 feet in 20
patients with equinovarus foot deformity between January 2015 and
December 2018 was done. Patients underwent gradual deformity
correction and triple fusion with Ilizarov fixator. Foot was assessed
for any residual deformity and shortening. Functional outcome and
patient satisfaction were assessed by Ankle Hind Foot Scale (AHFS)
and Likert scale, respectively using paired t-test. Final analysis was
done with Statistical Package for Social Sciences (SPSS) software
version 21.0.
Results: Twelve males and eight females with mean age of
15.9±3.4 years fulfilled the inclusion criteria and were included for
final analysis of results. Fusion rate was 86.1% with mean union
time of 12.5 weeks. Mean AHFS improved from 61.27 before
surgery to 76.9 which was statistically significant (p<0.0001).
One or more complications were seen in 15 (68.1%) feet but
were managed satisfactorily without any significant impact on
final outcome. Patient satisfaction rate for the procedure was
80%. After a mean follow-up of 18.1 months, plantigrade foot
with equal foot length was obtained in all patients.
Conclusion: Triple arthrodesis with gradual deformity correction
by Ilizarov technique effectively corrects equinovarus foot
deformity and foot length discrepancy. Known complications of
acute deformity correction can be avoided with equally good
results. It corrects deformity and restores alignment of foot
more accurately leading to a high patient satisfaction rate. |
