What does Engel's angle measure?

• A. The angle between first and second metatarsal
• B. The angle between the second metatarsal and the intermediate cuneiform
• C. The angle of the foot arch
• D. The dorsal-flexion angle at the MPJ

Answer: (B)

Engel's angle specifically measures the angle between the second metatarsal and the intermediate cuneiform. This angle is particularly relevant in evaluating the structural relationships in the forefoot and can provide insights into various foot deformities and conditions, such as hallux valgus. A normal Engel's angle can indicate appropriate alignment and function of the second metatarsal in relation to the cuneiform bones, which is crucial for proper load distribution and functionality of the foot during gait. The other options measure different anatomical relationships or aspects of the foot but are not related to Engel's angle. For instance, the angle between the first and second metatarsal is an important measurement in assessing conditions like bunions but does not pertain to Engel's angle. The foot arch angle assesses the height and structure of the medial longitudinal arch, while the dorsal-flexion angle at the metatarsophalangeal joint pertains to joint mobility and range of motion, which are separate evaluations when considering foot mechanics and pathologies.
