Early results of Ponseti treatment in 14 children (17 feet) aged between 2 and 10 years at the start of treatment are assessed.

Method and Results 14 children aged between 2 and 10 years (mean 5.4) presented with relapsed or under- corrected club feet. All had previous treatment with strapping and bebax or pedro boots. 8 had subsequently undergone posterior release of the Achilles tendon, ankle and subtalar joint through a longitudinal posterior incision.

All patients presented with absent heel strike, walking on the lateral border of the foot. 14 feet had a varus heel and 15 had an internal foot progression angle. Mean Pirani score was 2.14. Photographs and videos were taken. Ponseti casting was implemented. 15 feet required an Achilles tenotomy, and 15 feet had a tibialis anterior transfer to help maintain the correction.

Pirani scores improved from a mean of 2.64 to 0.21 in the group that had had previous surgery, and 1.64 to 0.07 in those that had had previous conservative treatment. All patients achieved a heel strike and ceased to walk on the lateral border of the foot. Heel varus corrected in 11/14 and partially corrected in 3. Internal foot progression resolved in 12/15 and improved in 3.

At latest follow up (16 months- 20 months), all transfers were working and all patients walked with heel strike and a plantargrade foot. 2 patients required further casting for relapse in forefoot adductus, and one for recurrent posterior tightness.

Conclusions The Ponseti method has been successful in the under corrected or relapsed club foot in children aged between 2 and 10 years in this series, including those with previous surgical intervention.

Introduction: Fibular hemimelia (FH) is a congenital limb reduction deficiency characterised by partial or complete absence of the fibula and a spectrum of associated anomalies. For children with a major anticipated limb length discrepancy and severe foot deformity, management (amputation or limb reconstruction) is controversial.

Materials and Methods: 8 children who are now adults (average age 28 years) underwent limb reconstruction as children in one of two UK centres for severe fibular hemimelia. All 8 participants were recalled to our institution for instrumented gait analysis. The SF-36 and lower limb domains of the Toronto Extremity Salvage Score (TESS) questionnaires were also administered.

Results: Partcipants scored well for general health but had functional limitations reflected in lower TESS scores. Kinematic analysis revealed decreased sagittal knee motion and valgus knee alignment. Also ubiquitous were anterior pelvic tilt and obliquity with incomplete hip extension and reduced range of hip abduction. Kinetic analysis showed reduced peak plantar flexion moment with reduced push-off power and an internal hip adduction moment in late stance. These parameters are compared to control data for below knee amputees.

Discussion and conclusions: Although the number of participants is small, this is the first study to use instrumented gait analysis for severe fibular hemimelia managed with limb reconstruction. The results add objective data to the debate over limb reconstruction or amputation in this group of children.
