Origin, medial process of calcaneal tuberosity, flexor retinaculum, and plantar aponeurosis; insertion, medial side of proximal phalanx of great toe; action, abducts great toe; nerve supply, medial plantar.

Injections of the MTP joint capsule included the medial collateral ligament (1), the medial collateral ligament and abductor hallucis tendon insertion (1), and plantar plate (1) at the first MTP joint.
Nerve conduction studies (NCSs) revealed an elongation of the distal motor latency of the left tibial nerve on the abductor hallucis muscle (4.10 ms on left side versus 3.05 ms on right side), slowing of the motor nerve conduction velocity (37.6 m/s on left side vs.
In 42/50 (84 %) of the fetal specimens, the PA covered the plantar surface of the first muscular layer of the foot, which comprised of the abductor hallucis, flexor digitorum brevis, and the abductor digiti minimi muscles (from medial to lateral).
Motor evoked potentials were elicited by transcranial stimulation (corkscrew electrodes on C1-C2, train of five stimuli, duration: 0.05 ms, interstimulus interval: 4 ms, intensity: 380 V) and were bilaterally recorded by needle electrodes (12 mm) on the abductor pollicis brevis, tibialis anterior and abductor hallucis muscles.
abductor hallucis. Patients received instructions to notify the investigator if their PPT was reached; subsequently the associated pain score (NRS) was obtained.
Jung et al (2011) examined the effect of custom foot orthoses alone or in combination with 'short foot exercises' on the cross sectional area of abductor hallucis, measured using ultrasound, and the strength of flexor hallucis longus, assessed using a digital dynamometer over 8 weeks.
Then the abductor hallucis muscle was identified on the medial side of foot and released completely from its origin or even excised.
Para la realizacion de los estudios de conduccion nerviosa del nervio tibial se coloco el electrodo activo a nivel del vientre muscular del abductor hallucis a 0.5 cm por debajo del tuberculo del escafoides y para el Nervio Peroneo en el vientre muscular del extensor digitorum brevis, los electrodos de referencia a 4 cm del electrodo activo sobre una superficie osea.
Then the abductor hallucis muscle was identifieid on the medial side of foot and released completely from its origin or even excised.
As the phalanx becomes misaligned, the abductor hallucis can contribute to pronation while the extensor hallucis longus becomes an adducting force on the phalanx, promoting progression of the deformity (Fig.
Flexor Hallucis Longus Transfer {Modified Wapner's (10, 11)}: A longitudinal incision was made on the medial border of the foot just above the abductor hallucis muscle, extending from the head of the first metatarsal to the navicular.
In the extensor compartment of the leg, we did not observe any muscular abnormalities, and no evidence of wasting or hypertrophy of muscles located on the dorsum of the foot and no evidence of hypertrophy, The deep fibular nerve (DFN) maintained the same relationship with the ATA, travelling together anterior to the interosseus membrane, The PTA branching pattern was observed normal, bifurcating posterior to the abductor hallucis to give the medial and lateral plantar arteries.
