Evaluation of Clinical Features and Surgical Outcomes of the Too Long Anterior Process in Children

Study Overview
=================
Brief Summary
-----------------
Calcaneonavicular coalition represents approximately 1% of the population between 8 and 12 years. They are manifested by repeated ankle sprains or by pain. - The diagnosis is radiological on an X-ray of the foot in oblique-3/4 incidence as well as magnetic resonance imaging. Treatment is second-line surgery after failure of orthopedic treatment. This surgery is either by direct approach or by arthroscopy, by performing a bone resection to recreate sufficient space in the joint in question. The patients in this study will only be operated on openly.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Comparison of scores before surgery and after surgery at 1 month, for all the operated patients | Calculation of the American Orthopaedic Foot and Ankle Society Score. This is an instrument for measuring the outcome of treatment in patients who sustained a complex ankle or hindfoot injury. It combines a clinician-reported and a patient-reported part. The maximal score is 100 points, indicating no symptoms or impairments. | 1 month | 
| Comparison of scores before surgery and after surgery at 3 months for all the operated patients | Calculation of the American Orthopaedic Foot and Ankle Society Score. This is an instrument for measuring the outcome of treatment in patients who sustained a complex ankle or hindfoot injury. It combines a clinician-reported and a patient-reported part. The maximal score is 100 points, indicating no symptoms or impairments. | 3 months | 
| Comparison of scores before surgery and after surgery at 1 12 months for all the operated patients | Calculation of the American Orthopaedic Foot and Ankle Society Score. This is an instrument for measuring the outcome of treatment in patients who sustained a complex ankle or hindfoot injury. It combines a clinician-reported and a patient-reported part. The maximal score is 100 points, indicating no symptoms or impairments. | 12 months |
