Aim. Historically, surgeons have focused on isolated simple coalition resection in symptomatic tarsal coalition with concomitant rigid flat foot. However, recent evidence suggests that coalitions with severe preoperative planovalgus malposition treated with resection alone are associated with continued disability and deformity. We believe that concomitant severe flatfoot should be considered as much as a pathological component and pain generator as the coalition itself. Our primary hypothesis is that simple resection of middle facet tarsal coalitions and simultaneous flat foot reconstruction can improve clinical outcomes. Method. We identified eleven children (13 feet) who had resections of middle facet tarsal coalitions with or without complex foot reconstruction (calcaneal lengthening, medial cuneiform osteotomy) for concurrent severe planovalgus between 2003 and 2011. Clinical examination, American Orthopaedic Foot and Ankle Society (AOFAS) hind-foot scores, and radiographic assessments were evaluated after resection of middle facet tarsal coalitions with simultaneous flat foot reconstruction. Results. Isolated coalition resection provided short to intermediate term pain relief for three children that had this as a solitary procedure. Calcaneal lengthening osteotomy performed as an additional procedure in patients with very severe and stiff planovalgus provided excellent correction and symptomatic pain relief in all six patients (Mean AOFAS: 91). Two patients had insertion of sinus tarsi implants in addition to resection also had satisfactory hind foot function (Mean AOFAS: 87.3) post operatively. Conclusion. This study shows that calcaneal lengthening osteotomy in addition to coalition resection in patients with severe rigid flat feet provides excellent pain relief and function. Rigid flat feet should be considered as a significant contributor to the pain complex in this cohort of patients

Purpose. To establish the early outcome, satisfaction and complications of sinus tarsi implants in the management of symptomatic flexible flatfeet for a paediatric population. Methods and results. We included all patients aged 18 years or less who were treated for flexible flatfeet with a sinus tarsi implant between January 2010 and June 2012. We excluded patients who had a history of clubfeet or tarsal coalition. 34 patients had 59 implants. The mean age at surgery was 13.7 yrs (9–17 yrs), with mean follow-up of 22 months (range 10–35). Mean AOFAS improved from 65.7 to 87.9 (p<0.001), with an improvement in AOFAS pain scores (p=0.0001). Radiographic correction occurred in all feet, with average improvement of the anteroposterior talar-second metatarsal angle of 16 degrees, and the lateral talar-first metatarsal angle of 9 degrees. Implant placement satisfaction rate was 86%, with 81% claiming that they would have the procedure again. Complications included peroneal spasm (8%), extrusion (7%), revision (5%), and removal (5%). Peroneal spasm was recalcitrant in 3 of the 5 cases, and those with spasm had a higher average forefoot abduction measurement (35 degrees) than the remaining treated cases (25 degrees). Conclusion. In paediatric patients with flexible flatfeet, utilisation of the sinus tarsi implant has good short-term outcome, with our failure and revision rates comparable to other published studies in the adult population. We introduce the concept of isolated subtalar hyperlaxity which appeared to be a distinct etiological factor. A learning curve in assessing implant size was noted. Overcorrection and implant migration were the indications for revision surgery. Severe forefoot abduction appears to have a poorer outcome, and may be associated with peroneal spasm. Level of evidence: IV

We present the validation of a translation into Danish of the Oxford ankle foot questionnaire (OxAFQ). We followed the Isis Pros guidelines for translation and pilot-tested the questionnaire on ten children and their parents. Following modifications we tested the validity of the final questionnaire on 82 children (36 boys and 45 girls) with a mean age of 11.7 years (5.5 to 16.0) and their parents. We tested the reliability (repeatability (test–retest), child–parent agreement, internal consistency), feasibility (response rate, time to completion, floor and ceiling effects) and construct validity. The generic child health questionnaire was used for comparison. We found good internal consistency for the physical and the school and play domains, but lower internal consistency for the emotional domain. Overall, good repeatability was found within children and parents as well as agreement between children and parents. The OxAFQ was fast and easy to complete, but we observed a tendency towards ceiling effects in the school and play and emotional domains. To our knowledge this is the first independent validation of the OxAFQ in any language. We found it valid and feasible for use in the clinic to assess the impact on children’s lives of foot and/or ankle disorders. It is a valuable research tool.

In a prospective study over 11 years we assessed the relationship between neonatal deformities of the foot and the presence of ultrasonographic developmental dysplasia of the hip (DDH). Between 1 January 1996 and 31 December 2006, 614 infants with deformities of the foot were referred for clinical and ultrasonographic evaluation. There were 436 cases of postural talipes equinovarus deformity (TEV), 60 of fixed congenital talipes equinovarus (CTEV), 93 of congenital talipes calcaneovalgus (CTCV) and 25 of metatarsus adductus.

The overall risk of ultrasonographic dysplasia or instability was 1:27 in postural TEV, 1:8.6 in CTEV, 1:5.2 in CTCV and 1:25 in metatarsus adductus.

The risk of type-IV instability of the hip or irreducible dislocation was 1:436 (0.2%) in postural TEV, 1:15.4 (6.5%) in CTCV and 1:25 (4%) in metatarsus adductus. There were no cases of hip instability (type IV) or of irreducible dislocation in the CTEV group.

Routine screening for DDH in cases of postural TEV and CTEV is no longer advocated. The former is poorly defined, leading to the over-diagnosis of a possibly spurious condition. Ultrasonographic imaging and surveillance of hips in infants with CTCV and possibly those with metatarsus adductus should continue.
