Hallux valgus | Radiology Reference Article | Radiopaedia.org
2024年8月7日 · A normal first metatarsophalangeal angle is ≤15° on an AP weight-bearing foot radiograph 2; anything greater indicates hallux valgus where the head of the first metatarsal is deviated medially. The intermetatarsal angle should be <9° on a weight-bearing foot radiograph 2. Other associated radiographic features include:
Hallux Valgus - Foot & Ankle - Orthobullets
Hallux Valgus, commonly referred to as a bunion, is a complex valgus deformity of the first ray that can cause medial big toe pain and difficulty with shoe wear. Diagnosis is made clinically with presence of a hallux that rests in a valgus and pronated position.

The hallux abductus angle (HAA) represents the angular relationship between Lines A and C with a normal range between 0–15 degrees (increased to approximately 30 degrees here). And the metatarsal-sesamoid position (MSP) is the positional relationship between Line A and the tibial sesamoid (increased to approximately position 5 here, as ...

2016年8月22日 · Hallux Abductus Angle. The hallux abductus angle (Figure 13-3C) is defined as the angulation between the longitudinal bisection of the first metatarsal and the longitudinal bisection of the hallux proximal phalanx. 1,2,7,21,26 In a normal lower extremity, the hallux is approximately parallel to the second toe, and 15° abducted or less relative ...

Hallux abductus (HA) angle—This angle is defined by the longitudinal bisections of the hallucal proximal phalanx and the first metatarsal, and is measured on the dorsoplantar radiograph (Fig. 1). Values greater than 20° are often pathologic and correlate with severity of deformity ( 32 ).

2016年6月16日 · The following angles were measured from the AP view: AP Meary's angle, hallux abductus angle, hallux interphalangeal angle, first intermetatarsal angle, fourth intermetatarsal angle, joint line convergence angle of first hallux interphalangeal joint, joint line convergence angle (JLCA) of first metatarsal cuneiform joints, JLCA of first ...
Hallux abductus interphalangeus in normal feet, early-stage hallux …
The objective of the present study was thus to determine if significant differences in HIPA exist in the early stages of hallux valgus or hallux limitus deformities. Methods: The hallux interphalangeal angle was measured in three groups of participants: a control group with normal feet (45 participants), a hallux valgus group (49 participants ...

(B) The metatarsus adductus angle (MAA) shows the angular relationship of the midfoot with respect to the second metatarsal mid-diaphyseal line. (C) The normal mechanical axis deviation (MAD) is 4 (range 2 to 6) mm lateral. (D) Anteroposterior view measurements. HAA, hallux abductus angle; HIA, hallux interphalangeal angle.

2000年1月1日 · The results showed that metatarsus primus adductus, increased metatarsal width, and a positive first metatarsal protrusion distance were associated with hallux valgus, whereas increased hallux interphalangeal angle was associated with hallux limitus.
