clubfoot; normal foot

Eligibility Criteria

• Age: 1 Month - 6 Months
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17)
• Sampling Method: Non-Probability Sample

Study Population

Thestudy population will consist of infants aged 1 to 12 months diagnosed with unilateral idiopathic clubfoot who present to the Orthopedic and Trauma Surgery Department at Assiut University Hospitals. Each participant will have one affected (clubfoot) limb and one normal contralateral foot, allowing for within-subject comparative measurements. Only infants with idiopathic, non-syndromic clubfoot deformity will be included to ensure homogeneity of the study group. Participants must have no history of previous foot surgery, no contralateral deformities, and no contraindications to ultrasound assessment. Parents or legal guardians of eligible infants will receive a full explanation of the study purpose and procedures prior to enrollment. Participation will be voluntary and based on written informed consent. A total sample of 40 infants (40 affected feet and 40 contralateral normal feet) will be recruited as a pilot population for measurement and comparison of Achilles tendon-neurovascula

You may qualify if:

• Infants aged 1-6 months
• Unilateral clubfoot deformity and a normal opposite foot

You may not qualify if:

• Non-idiopathic or syndromic clubfoot
• Previous foot surgery , contralateral foot deformity
