Floating toe syndrome is most commonly attributed to which muscle tendon?

• A. Flexor Digitorum Longus
• B. Flexor Digitorum Brevis
• C. Extensor Digitorum Longus
• D. Tibialis Posterior

Answer: (A)

Floating toe syndrome occurs when the toes fail to maintain ground contact during stance because the balance between toe flexors and the intrinsic toe-stabilizing muscles is disrupted. The flexor digitorum longus is the tendon most closely tied to this imbalance. Its long, powerful pull on the distal phalanges can dominate the toe’s loading pattern, making it difficult for the intrinsic muscles to keep the toe pressed to the ground. This extrinsic long flexor’s influence on toe posture is the most common culprit behind a toe that “floats.” The other options don’t fit as well because they don’t have the same dominant role in maintaining toe ground contact. The extensor digitorum longus tends to extend the toes, which would more likely contribute to elevation rather than a lack of contact. The flexor digitorum brevis acts more locally at the proximal joints with less influence on the distal loading pattern that leads to floating, and the tibialis posterior primarily affects hindfoot stability and arch support rather than direct toe-ground interaction.
