[Early results of the Ponseti method for the treatment of idiopathic clubfoot].

AIM: The Ponseti method for the treatment of congenital clubfeet has been propagated due to the sometimes disappointing functional results after surgical treatment. The aim of our study was to evaluate our early results and experiences with the Ponseti method.

METHOD: Between December 2002 and December 2004 a total of 87 clubfeet in 59 patients were treated using the Ponseti method at our department. Only patients in whom treatment was initiated within the first three weeks of life were included in this study. Rate of successful correction without open release surgery, radiological findings, classification according to Pirani at the time of the last follow up, recurrence rate and duration of treatment were defined as outcome measures for this prospective study.

RESULTS

Fifty-nine cases in 37 patients met the inclusion criteria. Ninety-three percent of all cases (55 feet) were corrected without open surgery. The mean duration of active treatment was 11.4 weeks (8-20 weeks). The mean tibiocalcaneal angle 3-4 weeks after the percutaneous tenotomy of the Achilles tendon was 69 degrees, the mean a.-p.-talocalcaneal angle measured 33 degrees and the lateral talocalcaneal angle 36 degrees. A recurrence was seen in one patient with bilateral clubfeet (3.6 %).

CONCLUSION

Open release surgery can be averted in most cases of idiopathic clubfoot using the Ponseti method. Scarring of the soft tissue and especially of the joint capsule can thereby be avoided.
