Managing the Severe Cavus Foot Deformity in Global Humanitarian Programs.

Area of Science:

• Orthopedic Surgery
• Foot and Ankle Deformities

Background:

• Cavus foot is a complex deformity with varied causes, from idiopathic to neuromuscular.
• Successful treatment necessitates a deep understanding of the multiplanar deformity, muscle imbalance, and hindfoot rigidity.

Purpose of the Study:

• To outline a systematic approach for the surgical correction of cavus foot deformities.
• To simplify the surgical treatment algorithm for cavus foot.

Main Methods:

• Identifying the location and apex of multiplanar deformities.
• Utilizing osteotomies or arthrodesis to correct the primary deformity.
• Performing tendon transfers to address muscular imbalances and prevent recurrence.

Main Results:

• Surgical correction is simplified by understanding the deformity's location and apex.
• Combined bony correction and tendon transfers are crucial for preventing recurrence.
• An algorithmic approach can guide surgical decision-making.

Conclusions:

• A thorough understanding of cavus foot biomechanics and deformity is essential for successful surgical outcomes.
• Addressing both the bony deformity and muscular imbalance is key to preventing recurrent cavus foot.
• The described principles allow for a simplified, algorithm-driven surgical strategy for cavus foot correction.
