Summary
Children treated for clubfoot often exhibit foot inturning. This study found significant inturning in treated clubfeet, linked to adductus and torsional issues, impacting gait progression.
Area of Science:
- Orthopedics
- Pediatric Orthopedics
- Biomechanics
Background:
- Clubfoot is a common congenital foot deformity.
- Inturning of the foot (in-toeing) can persist after surgical correction.
- Understanding the causes of residual in-toeing is crucial for optimal treatment outcomes.
Purpose of the Study:
- To quantify the foot progression angle in children treated for clubfoot without subtalar release.
- To identify factors contributing to residual foot inturning in treated clubfeet.
Main Methods:
- Foot progression angle was measured using the Shutrack carbon paper system.
- A cohort of 52 treated clubfeet was compared to 43 age-matched controls.
- Statistical analysis was performed to identify contributing factors.
Main Results:
- Treated clubfeet showed a mean foot progression angle of -5 degrees, indicating significant inturning.
- This represents a 13-degree deviation from the normal mean of 8 degrees.
- Forty-eight percent of treated clubfeet had inturning exceeding 2 standard deviations from the norm, associated with adductus and torsional deformities.
Conclusions:
- Foot inturning is a common residual issue after clubfoot release surgery without subtalar release.
- Adductus and internal tibial/femoral torsion are significant contributors to this inturning.
- Varus deformity often accompanies inturning, but inturning can occur independently.

01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:28Muscles of the Leg that Move the Foot and Toes
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.

01:13Angle of Twist: Problem Solving
An electric motor applies a torque of 700 N·m to an aluminum shaft, triggering a stable rotation. Two pulleys, B and C, are subjected to torques of 300 N·m and 400 N·m, respectively. The modulus of rigidity is provided as 25 GPa. With the knowledge of the length and diameter of each segment, the twist angle between the two pulleys can be computed. First, a section cut is made between pulleys B and C, and the cut cross-section is analyzed using a free-body diagram. Given that the torque exerted...
01:25Design Example: Traverse Angle Computations
Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...
01:20Elevation of Intermediate Points on Vertical Curves
Vertical curves are essential in roadway design because they provide smooth transitions between varying roadway grades. Designing vertical curves involves calculating intermediate elevations and identifying the curve's highest or lowest point, which is essential for optimal roadway performance.Intermediate elevations on a vertical curve are determined using the tangent offset method. This method considers the initial elevation at the start of the curve, the grades, and the curve's geometry. The...
