Failed Cavovarus Reconstruction: Reconstructive Possibilities and a Proposed Treatment Algorithm

This article provides an overview of the techniques and strategies to address a failed cavovarus deformity correction. These problems pose significant challenges to the treating surgeons and should be accurately planned before embarking on surgery.

Correction of neglected idiopathic club foot by the Ponseti method

The Ponseti method of treating club foot has been shown to be effective in children up to two years of age. However, it is not known whether it is successful in older children. We retrospectively reviewed 17 children (24 feet) with congenital idiopathic club foot who presented after walking age and had undergone no previous treatment. All were treated by the method described by Ponseti, with minor modifications. The mean age at presentation was 3.9 years (1.2 to 9.0) and the mean follow-up was for 3.1 years (2.1 to 5.6). The mean time of immobilisation in a cast was 3.9 months (1.5 to 6.0).

A painless plantigrade foot was obtained in 16 feet without the need for extensive soft-tissue release and/or bony procedures. Four patients (7 feet) had recurrent equinus which required a second tenotomy. Failure was observed in five patients (8 feet) who required a posterior release for full correction of the equinus deformity.

We conclude that the Ponseti method is a safe, effective and low-cost treatment for neglected idiopathic club foot presenting after walking age.

Neuropathic osteoarthropathy in the diabetic foot

OBJECTIVE

To discuss a case involving a 55-year-old diabetic woman with neuropathic osteoarthropathy initiated by a fall.

CLINICAL FEATURES

The patient fell into a hole, injuring her left foot. Because of the anesthesia associated with her diabetic peripheral neuropathy, she did not notice the ensuing plantar puncture wound. The patient assumed that her swelling was a result of a sprain. Mild dislocation and osseous fragmentation was noted within the midfoot on radiographs. The neuropathic osteoarthropathy progressed until the patient was later casted. Plain films taken at the time of cast removal demonstrated resorption and consolidation of fragmentation, but the dislocation was unaltered.

INTERVENTION AND OUTCOME

The patient was scheduled for surgery and wound debridement. However, before surgery, complications of a burn sustained on the contralateral foot required fifth ray amputation. Surgery of the left foot has been postponed until adequate postsurgical healing has occurred at the right foot amputation site.

CONCLUSION

This article provides tools for the timely diagnosis and treatment of neuropathic osteoarthropathy. An increased understanding of this entity will help lead to a reduction in the incidence of delayed treatment resulting from misdiagnosis.
