The adult cavus foot

Area of Science:

• Orthopedic surgery
• Foot and ankle reconstruction
• Biomechanical analysis of foot deformities

Background:

• Cavovarus foot deformity presents a spectrum of severity, from subtle flexible to rigid presentations.
• Accurate clinical assessment and weight-bearing radiographs are crucial for identifying deformity apex and planning correction.
• Surgical intervention is considered when conservative management fails to achieve a plantigrade and balanced foot.

Purpose of the Study:

• To review the classification and management strategies for cavovarus foot deformity.
• To discuss the indications for different surgical approaches based on deformity severity and flexibility.
• To highlight joint-sparing techniques and arthrodesis in the context of cavovarus foot correction.

Main Methods:

• Review of current literature on cavovarus foot deformity classification and treatment.
• Analysis of surgical techniques including soft-tissue releases, tendon transfers, and osteotomies.
• Evaluation of treatment outcomes based on deformity characteristics and patient conditions like Charcot-Marie-Tooth disease.

Main Results:

• Mild, flexible cavovarus feet benefit from joint-sparing surgery, even in Charcot-Marie-Tooth disease.
• Severe, rigid cavovarus feet or degenerative cases are best managed with arthrodesis.
• Surgical aims include achieving a plantigrade and balanced foot through various reconstructive procedures.

Conclusions:

• Cavovarus foot management requires tailored approaches based on deformity severity and flexibility.
• Joint-sparing surgery is preferred for flexible deformities, while arthrodesis is reserved for severe or rigid cases.
• Achieving a plantigrade and balanced foot is the primary goal of surgical correction in cavovarus deformity.
