Insights
This study found moderate correlations between pedobarographic and radiographic measures in surgically treated congenital talipes equinovarus (CTEV) feet. Pedobarography offers a more direct functional assessment of ground contact force compared to radiographic methods.
Area of Science:
- Orthopedics
- Biomechanical Engineering
- Pediatrics
Background:
- Congenital talipes equinovarus (CTEV) is a complex foot deformity requiring surgical correction.
- Assessing treatment outcomes for CTEV often involves both radiographic and functional measures.
- Understanding the correlation between these measures is crucial for effective patient management.
Purpose of the Study:
- To evaluate the relationship between pedobarographic and radiographic parameters in surgically treated CTEV patients.
- To determine if functional foot measurements correlate with structural imaging findings.
Main Methods:
- A cohort of 50 patients (70 feet) surgically treated for CTEV was analyzed.
- Simultaneous radiographic and selective pedobarographic measurements were taken.
- Pearson's and Spearman's correlation coefficients were used to assess relationships.
Main Results:
- Moderate correlations were observed between pedobarographic and radiographic measures in surgically treated CTEV.
- Strongest positive correlations included right heel rise with calcaneal-5th metatarsal angle (r=0.54) and talo-1st metatarsal angle (r=0.48).
- Lateral tibiocalcaneal angle showed a strong positive correlation with left heel rise (r=0.42).
Conclusions:
- Pedobarographic and radiographic measures show moderate correlation in surgically treated CTEV.
- Pedobarography provides a direct assessment of ground contact force, offering greater functional insight.
- Functional pedobarographic data may complement radiographic findings in evaluating CTEV treatment outcomes.
Objectives:
This study aims to assess the correlation between selective pedobarographic and radiographic measures in patients with surgically treated congenital talipes equinovarus (CTEV).
Patients And Methods:
We examined 50 patients [70 feet; 34 girls (68%) and 16 boys (32%); mean age 11.2 months; range 3-30.6 months] surgically treated for CTEV with a mean follow-up of 8.7 years (range 4.3 to 15 years). Patients had radiographic and pedobarographic measurements simultaneously. The right and left feet were assessed separately. The relationship between selective pedobarographs and standing weight-bearing radiographs of the foot was assessed by the Pearson's correlation coefficient and the Spearman's rank correlation coefficient.
Results:
There were moderate correlations between selective pedobarographic and radiographic measures in surgically treated CTEV patients. The strongest positive correlations were between the right heel rise and right anteroposterior calcaneal-5(th) metatarsal angle (r=0.54, p=0.001) and, the right anteroposterior talo-1(st) metatarsal angle (r=0.48, p=0.003). A similar strong positive correlation was observed between lateral tibiocalcaneal angle and left heel rise parameters (r=0.42, p=0.01).
Conclusion:
There were moderate correlations between selective pedobarographic and radiographic measures of surgically treated CTEV. However, the pedobarographic measure is a direct measure of the contact force of the foot with the ground and therefore has a more direct functional implication than radiographic measures.
