Introduction: To review the medium term outcome of staged surgery for treating recalcitrant idiopathic talipes equinovarus.

Methods: Between 1988 and 1995, we studied 91 club feet from a series of 120 recalcitrant feet in 86 patients requiring surgical treatment. The initial results have been reported previously and this cohort has been subsequently followed up for between 7 and 15years. The mean age at initial operation was 8.9 months. Surgery consisted of an initial plantar medial release followed two weeks later by a posterolateral release. This strategy was used specifically to address the problems of wound healing associated with single-stage surgery and to ascertain the rate of relapse after a two-stage procedure. The feet were classified preoperatively and prospectively into four grades according to the system suggested by Dimeglio et al. Reported relapse at last review was 0.0% in grade 2, 20.4% in grade 3 and 65.4% in grade 4 feet. The rate of overall relapse was 30.8%. At 7 to 15 year review an additional 9.1% in grade 2, 7.4% in grade 3, 11.5% in grade 4 had relapsed. Overall a further 8.8% had relapsed and were treated with further surgery. Functional outcome of the group remains good with 95.6% overall finding no restrictions to activities.

Conclusion: This review confirms that the strategy of staged surgery is supported in the medium term when considering rates of relapse and functional outcome.
