Resistant clubfoot deformities managed by Ilizarov distraction histogenesis.
BACKGROUND
Resistant clubfoot deformities of the foot and ankle remain a difficult problem even for the most experienced surgeon. We report a series of neglected resistant clubfoot deformities treated by limited surgery and Ilizarov distraction histogenesis.


METHODS
Twenty one patients with 27 feet having resistant clubfoot deformities were managed by Ilizarov distraction histogenesis from April 2005 to May 2008. The mean age was 12 years (range 8-20 years). A limited soft tissue dissection like percutaneous Achilles sheath tenotomy and plantar fasciotomy were done. Progressive correction of the deformities was achieved through the standard and simple Ilizarov frame construct setting. After removal of Ilizarov frame, a short leg walking cast was used for an additional 6 weeks, followed by an ankle foot orthrosis for 3 months.


RESULTS
The mean followup period was 18.7 months (range 20-36 months). The mean duration of fixator application was 3.6 months (range 3-5 months). At the time of removal of the fixator, a plantigrade foot was achieved in 25 feet and gait was improved in all patients. There was residual varus hind foot deformity in two patients. Out of 27 feet, 3 (11.11%) were rated as excellent, 17 (62.96%) as good, 5 (18.51%) as fair, and 2 (7.40%) as poor according to Reinkerand Carpenter scale. Excellent and good results (74.07%) were considered satisfactory, while fair and poor results (25.92%) were considered unsatisfactory.


CONCLUSIONS
The short term clinical and functional results of resistant clubfoot deformities with Ilizarov's external fixator is promising and apparently a good option.
