Abstract
Aim
To compare outcomes for children treated for idiopathic clubfeet with the Ponseti regimen before (2002–2004) and after (2005–2006) implementation of a dedicated Ponseti service.
Method
A retrospective analysis of outcomes for all patients with idiopathic clubfeet treated in the 2 years before and after implementation of a dedicated Ponseti service was undertaken. Results were statistically analysed using Fisher's exact t-test.
Results
In the original cohort treated between 2002–2004, with an ad-hoc service where children were treated in general paediatric orthopaedic clinics by a number of different consultants, 100 feet in 66 children were treated. 96 feet (96%) responded to initial casting. 85 feet (85%) required tendo-achilles tenotomy. 31 feet had a recurrence within the first 2 years (16 of which were successfully treated by repeat casting and/or tenotomy and/or transfer of the tendon of tibialis anterior, the remaining 15 requiring extensive soft tissue release). Between 2005–2006, with a dedicated Ponseti service, 72 feet in 53 children were treated. 72 (100%) responded to initial casting. 60 feet (83.3%) required tendo-achilles tenotomy. Relapse of the initial deformity occurred within 2 years in 11 feet – 4 children required repeat serial casting, 3 feet required tendon of tibialis anterior transfer, 3 required repeat tenotomy of tendo-achilles and one foot required extensive soft tissue release.
Conclusion
Our results have shown that a dedicated Ponseti service leads to improved outcomes in the treatment of idiopathic clubfeet. We have shown a statistically significant reduction of recurrence (p=0.02) and extensive soft tissue release (0.002) in those children treated in a specialist service compared to an earlier ad hoc treatment programme.
