Aims. The aim of this study was to gain a consensus for best practice of the assessment and management of children with idiopathic toe walking (ITW) in order to provide a benchmark for practitioners and guide the best consistent care. Methods. An established Delphi approach with predetermined steps and degree of agreement based on a standardized protocol was used to determine consensus. The steering group members and Delphi survey participants included members from the British Society of Children’s Orthopaedic Surgery (BSCOS) and the Association of Paediatric Chartered Physiotherapists (APCP). The statements included definition, assessment, treatment indications, nonoperative and operative interventions, and outcomes. Descriptive statistics were used for analysis of the Delphi survey results. The AGREE checklist was followed for reporting the results. Results. A total of 227 participants (54% APCP and 46% BSCOS members) completed the first round, and 222 participants (98%) completed the second round. Out of 54 proposed statements included in the first round Delphi, 17 reached ‘consensus in’, no statements reached ‘consensus out’, and 37 reached ‘no consensus’. These 37 statements were then discussed, reworded, amalgamated, or deleted before the second round Delphi of 29 statements. A total of 12 statements reached ‘consensus in’, four ‘consensus out’, and 13 ‘no consensus’. In the final consensus meeting, 13 statements were voted upon. Five were accepted, resulting in a total of 31 approved statements. Conclusion. In the aspects of practice where sufficient evidence is not available, a consensus statement can provide a strong body of opinion that acts as a benchmark for excellence in clinical care. This statement can assist clinicians managing children with ITW to ensure consistent and reliable practice, and reduce geographical variability in practice and outcomes. It will enable those treating ITW to share the published consensus document with both carers and patient groups. Cite this article: Bone Joint J 2024;106-B(10):1190–1196

Purpose: The purpose of this study is to report on the outcomes of children with ITW who received Botulinum A Toxin (BTX-A) as an adjunct treatment to manipulations/casting and maintenance protocol.

Method: ITW severity was classified using gait analysis and defined by the absence of 1^st ankle rocker, early 3^rd rocker and an early and increased first ankle moment¹. Subjects who met the three severity criteria received a single BTX-A injection into both gastrocsoleus and placed immediately in below-knee casts. Casts were changed two weeks later for a total casting period of four weeks. Subjects then entered a maintenance protocol involving use of night splints or articulated ankle-foot-orthotics. Outcome measures collected at all follow-up visits were ankle dorsiflexion with knee in 90° flexion (DFF) and extension (DFE).

Results: Thirteen subjects with severe bilateral ITW participated. Subjects were followed for an average of 48 weeks (range 7 – 168 weeks) post BTX-A injection. Given the variability in subject outcomes, analyses and reporting were stratified according to subjects’ right and left feet. At day of BTX-A, right foot DFF/DFE were 1.7° ± 14.4 and −1.5° ± 13.0 and mean left DFF/DFE were −1.5° ± 12.8 and −6.5° ± 12.1. Immediate improvement following BTX-A (2 weeks) were seen as right foot DFF/DFE were 14.1° ± 10.0 and 6.3° ± 7.7 and left DFF/DFE were 9.6° ± 14.1 and 3.9° ± 10.6. At 4 weeks, right DFF/DFE were 16.6° ± 9.5 and 11.7° ± 9.1 and left DFF/DFE were 13.1° ± 8.6 and 7.3° ± 8.3. At the half-life of BTX-A (12 weeks), right DFF/DFE were 15.2° ± 12.2 and 10.8° ± 10.5 and left DFF/DFE were 15.8° ± 12.4 and 13.0° ± 11.6. At follow-up visits, correction was maintained as right DFF/DFE were 15.6° ± 9.1 and 10.4° ± 10.3 and left DFF/DFE were 16.9° ± 11.2 and 9.8° ± 10.7.

Conclusion: This is the first study to show early outcomes (improved DFF/DFE) following BTX-A injections in ITW and provides evidence for obtaining and maintaining the correction from a single BTX-A injection over a short-term follow-up period.

The purpose of the study was to document the outcome in adulthood of treatment for idiopathic toe walking. Twenty of 23 adults who had been previously treated for idiopathic toe walking from 1984 to 1990 were contacted. Three of the 20 subjects lived outside Auckland and four subjects declined to participate, giving a total of 13 subjects suitable for study. All but one of the subjects had had serial casts between the ages of 3.7 to 9.5 years. Six subjects had no further treatment while the other seven subjects went on to surgical lengthening of either TA or calf (average age 10.7 years). All participants underwent 3-D gait analysis and heel-rise test. Average follow-up was 10.8 years (range 5.4–15.6 years). Three patients still had signs of toe walking on visual observation of their gait. The maximum ankle dorsiflexion in stance averaged 90 on 3-D gait analysis (range 20 to 140). Eleven subjects showed maximum ankle dorsiflexion in stance greater than 2 standard deviations below normative values. Nine subjects had abnormal timing of maximal ankle dorsiflexion in stance with maximum ankle dorsiflexion prior to 50 percent of the gait cycle. Only two patients had ankle push off powers below normative values of 2 watts/kg. This is the first study to report on adults treated for idiopathic toe- walking as children. Most subjects showed restricted range and altered timing of ankle dor-siflexion in gait, however this was detectable visually in only three subjects
