Why does the thumb bone protrude?

summary

The thumb on the foot is a relatively hidden part, so even if there are often some problems, it will not be too harmful. But if there is a bone protruding next to the thumb on the foot, the situation will be more serious, because it is usually accompanied by other symptoms. Why is the thumb bone protruding? Let's talk about it

Why does the thumb bone protrude?

Standing for a long time, walking too much or often tight pointed shoes can lead to hallux valgus. Hallux valgus is a complication of flatfoot, and hallux valgus alone is rare. Because the connection between the first cuneiform bone and the first metatarsal bone and other cuneiform bone and metatarsal bone is loose, the first cuneiform bone and the first metatarsal bone move inward under improper load, resulting in the collapse of the longitudinal arch and transverse arch, and the toe of the foot moves outward due to the traction of the adductor muscle and the extensor longus femoris.

After deformation, the metatarsophalangeal joint of the great toe was subluxated, and the attachment of the medial joint capsule could have osteophyte hyperplasia due to traction. The prominent part of metatarsophalangeal joint has bursitis due to the conflict of upper, and even swelling and pain. Hallux valgus deformity is more common, but most patients have no performance, as long as a few patients have pain and dysfunction. The strain and atrophy of the metatarsophalangeal joint cartilage and the extrusion of the bursa are the direct causes of the appearance.

The main manifestation of hallux valgus is pain when walking, and the pain is mostly at the metatarsophalangeal joint of the thumb. We can see the hallux valgus, the first metatarsal adduction deformation, the second toe hammer toe, some swelling, tenderness. When complicated with Gangmu bursitis, the affected part may have redness, swelling and burning sensation. Valgus may exist for a long time, but it does not cause any discomfort, and the degree of pain is often inconsistent with the degree of deformation.

matters needing attention

As long as some patients suffer from the damage of the occipital bone and bursa at the toe joint, it may cause pain. Suffering from hallux valgus, doctors advocate to standard hospital to do check, and then determine, and must check early, early operation control condition.
