Abstract
Introduction: The Ponseti method has been adopted by many pediatric orthopaedic centers throughout Europe in the last years. The minimal invasive approach and the short duration of the active treatment phase have been the main reasons to change to the Ponseti method at our institution. We report the short term results of patients treated with the Ponseti method for idiopathic clubfeet and discuss experiences and pitfalls.
Material and Methods: From the end of 2002 on we have applied the treatment regime strictly as described by Ponseti himself. For this study we analyzed a group of patients comprising all patients treated for congenital idiopathic clubfoot according to the Ponseti protocol within the first three weeks after births. The need for open release surgery was the main outcome measurement in this group.
Results: Between December 2002 and July 2004 we treated a total of 59 clubfeet in 37 patients with the Ponseti method. Our patient population consisted of 14 female and 23 male patients. The mean Dimeglio score was 9.2 points (5–15 points). Using the Pirani score the mean midfoot score was 1.7 points (1–3 points), the mean hindfoot score was 2 points (0.5–3 points) and the mean total score was 3.8 points (2–6 points). Three feet in two patients were treated with Ponseti casting only (5 %) and did not need a percutaneous achilles tenotomy (pAT) or open release surgery. Fifty-two feet in 33 patients (88 %) were successfully treated with Ponseti casting and pAT. Four cases in two patients had to undergo a McKay Simons procedure (7 %). Thereby 93% of all cases were treated without open release surgery. Mean follow-up after the last cast was 7.4 months (3–16 months). A recurrence was seen in one patient representing two cases after about 8 months after pAT. The parents were non compliant with the abduction bar protocol and could not be convinced of the importance of the orthosis; a McKay Simons procedure was performed. No other cases of recurrence were observed during the follow up period.
Discussion: The Ponseti method should be applied as originally described, and especially, if more people are involved in the treatment, a standard treatment regime is desirable. As the compliance of the parents is a crucial factor, everything should be done to ensure that the treatment is made as easy for them as possible. Only if a full support for questions or problems with the casts and especially with the braces is available, a good compliance can be ensured. The minimal invasive approach utilized by the percutaneous tenotomy is the lead argument in favor of the Ponseti method. In cases of recurrence or residual deformity when open surgery is necessary, this secondary procedure is in fact primary surgery. Thereby the danger of massive scaring associated with limited range of motion, pain and disability after a second procedures is prevented.
