The Spleen(SP)

Abductor hallucis muscle: Abducts the great toe. However, its physiologic role in hallux abduction may be less important than its contribution to proper gait mechanics. The abductor hallucis assists the posterior tibial tendon in supporting and elevating the arch of the foot.5

Motor nerve conduction studies included median, ulnar, peroneal and tibial nerve studies. The median motor nerve was stimulated from the distal (wrist) and proximal (elbow) areas and recording was obtained from the abductor pollicis brevis muscle. The ulnar motor nerve conduction study was stimulated in the distal (wrist) and proximal (under elbow) areas and recording was obtained from the abductor digiti minimi muscle. The peroneal motor nerve was stimulated in distal (ankle) or proximal (knee) areas, respectively, and recording was made from the extensor digitorium brevis muscle. The tibial motor nerve was stimulated in distal (ankle) or proximal (popliteal fossa) areas, respectively, and a record was obtained from the abductor hallucis muscle. The distal motor latency was calculated as the time from stimulus to the initial compound muscle action potential (CMAP) deflection from baseline, and the amplitude of CMAP was measured from baseline to the negative peak.

Since a positive evolution was seen, a further conservative management was given. However, five months later, the patient presented at the emergency department with paresthesia of the right foot and difficulties in plantar flexion of the right foot since two days. Electromyography and nerve conduction study showed lowered compound muscle action potential of the abductor hallucis muscle without evidence for block of the peroneal nerve. Since the patient stopped wearing them, once again, compression stockings were advised with strict venous hygienic management. Nevertheless, 20 days later, an evolution towards unsustainable pain at the right foot was seen. New electromyography revealed a symptomatic TTS of the right site. A new MRI was planned and confirmed this finding in the tarsal tunnel area although difficulties in differentiation of the nerve structures were noticed. A combination of Contramal retard 100 mg (tramadol hydrochloride) and Neurontin 100 mg (gabapentine), both once daily, was associated to the anti-inflammatory drugs in an increasing dose. Eventually, 10 months after initial presentation, the increasing pain and the impossibility to treat the venous malformation as the external cause, obliged us to perform an open tarsal tunnel release through a retromalleolar incision. A tight retinaculum was identified and dissected (Figure 2). The abductor hallucis muscle was also identified and dissected for complete release of the lateral plantar nerve. A subcutaneous drain was left in situ and the skin was closed with nonabsorbable sutures. The procedure was uncomplicated. The drain could be removed on the first postoperative day. A visual analog scale (VAS) was performed preoperatively and on the first day postoperatively. This showed immediately excellent results with values of 9/10 and 2/10, respectively. Ten months postoperatively, the patient was still without any pain. Only a small area of hypoesthesia at the medial foot and toes remained.
Horizontal Heterophoria Modifications by Means of Thin Proprioceptive Stimulations Applied on the Foot Sole: A Randomised Study
Published in Journal of Motor Behavior, 2022
The Internal Heel Wedges (IHW) were positioned on the abductor hallucis muscle of both feet. To position them correctly, the operator asked the subjects, in the standing position, to push their big toe in abduction against a resistance offered by his thumb, while with the other hand he identified the muscle insertion of the abductor hallucis on the heel. Then, a vertical line was drawn at the insertion point of the muscle (Figure 4).
