Study summary

Real-life, observational, monocentric, ambispective study, carried out in France. The aim of the study is to evaluate the success rate of orthopedic management of the Z-foot after at least 9 months of follow-up.

Read the detailed description

The study will include a single prospective data collection, which will make it possible to obtain prospective clinical data at the longest follow-up after treatment, with a minimum follow-up of 9 months. This collection will be done during a visit to the office or a phone call, depending on the preference of patients and their parents.

Early data (before the intervention, immediately after, and at 3 months of follow-up) will be collected retrospectively in medical records.

Study population

Children who suffered from a congenital idiopathic Z-foot deformation, aged 6 months to 2 years at the time of orthopedic treatment.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Child having presented a congenital idiopathic malformation uni- or bilateral of foot in Z, defined by the presence of an angular adduction of the mid-forefoot and a dorsolateral hump;
  • Orthopedic treatment with femoropedic plasters and slotted splints in 1st intention, having started at least 9 months before inclusion;
  • Child aged 6 months to 2 years at the start of care;
  • Authorization of the parents or the legal representative of the child to collect personal information about their child.

Exclusion criteria

Exclusion Criteria:

  • Child having presented a secondary Z foot;
  • History of foot surgery;
  • Lack of retrospective data to assess the convexity of the external edge of the foot before orthopedic care;
  • Inability of the parents or the child's legal representative to understand the study protocol.

What researchers measure

Primary outcomes

  1. The main criterion of the study is the success rate of orthopedic management of the Z-foot.

    Success is a composite criterion, measured at the last follow-up, defined by: * Outer edge of the straight foot; AND * Absence of dorsolateral hump OR possibility of putting on shoes without difficulty AND * Absence of recurrence of the malformation OR resumption of surgery OR resumption of orthopedic treatment.

    Time frame: 9 months

Secondary outcomes

  1. Moderate success rate of the procedure

    Defined by an external edge of the foot that is not rectilinear but the possibility of normal footwear, at the greatest distance (relative to the number of feet treated)

    Time frame: 9 months

  2. Partial and total success rate (relative to the number of patients treated)

    * Total success rate: (number of patients with unilateral involvement and foot treated successfully + number of patients with bilateral involvement and both feet treated successfully) / total number of patients. * Partial success rate in patients with bilateral involvement: number of patients with only one of the 2 feet treated successfully / number of patients with bilateral involvement.

    Time frame: 9 months

  3. Convex angle of the outer edge of the foot during follow-up

    The evolution of the convexity angle of the external edge of the foot will be studied during treatment and follow-up, in a mixed model with repeated measurements, with the initial severity of the malformation as a cofactor (angle ≤ 15 ° /\> 15 ° ).

    Time frame: 9 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 15, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
