What is the first metatarsophalangeal joint and what is the first segment of the metatarsal

Upstairs interesting! To put it simply, it's the joint where the toe meets the ball of the foot.

Gout. Prone to people.

Middle-aged males. Corpulent.

Brainwork. Incentive.

High-purine diet.

Cold. Fatigue.

Drinking. Prone areas.

First metatarsophalangeal joint.

Generally, an acute attack will be self-limited, and it will get better in about a week.

Typically, there will be redness, swelling, heat, and pain at the first metatarsophalangeal joint.

It is recommended that you check the blood uric acid, and it is OK to see if it is high.

If you are high, you must pay attention to diet and rest, take medicine, etc., otherwise it will become chronic and it will not be cured, and it will be very painful.

The metatarsal bones are located in the middle of the foot and there are 5 pieces in total. From the inside to the outside, they are called the first metatarsal, the second metatarsal, the third metatarsal, the fourth metatarsal, and the fifth metatarsal. Each metatarsal bone is divided into three parts: the base (near the end of the heel), the body, and the head (the end near the toe).

There is a metatarsal tuberosity below the base of the first metatarsal, and a milky protrusion on the lateral side of the base of the fifth metatarsal called the fifth metatarsal tuberosity (located in the middle of the lateral side of the foot).

The lower end of the tibia and fibula of the lower leg and the talus form the largest joint in the foot, the ankle joint, and the joint on the back side of the foot. Joints are formed between the tarsal bones and between the tarsal bones and the metatarsals. The metatarsophalangeal joint is formed between the metatarsal bone and the phalangeal bone, and the interphalangeal joint is formed between the phalangeal bone and the phalangeal bone.

The second to fifth toes can be referred to as the proximal and distal interphalangeal joints. Regardless of the size, range of motion and direction of the joint, its basic structure should include three parts: the articular surface, the joint capsule and the joint cavity, and there are ligaments to enhance its stability.

1.Medial foot palpable medial malleolus, scaphoid tuberosity (approximately cm anterior to medial malleolus), first metatarsal base tuberosity, and first metatarsal head.

2.Lateral to foot The lateral malleolus, the tuberosity at the base of the fifth metatarsal, and the small head of the fifth metatarsal are palpable.

3.The soles of the feet are palpable in the calcaneal tuberosity below the heel, the first to fifth metatarsal small heads, and the basal bulge of the first to fifth metatarsals.

4.The dorsum of the foot is palpable at the base of the second to fourth metatarsals.

5.The arch of the foot consists of the tarsal bones and metatarsal bones being stretched by ligaments, muscles, fascia to form an arch that protrudes to the back, called the arch of the foot. The main arch is the medial longitudinal arch, consisting of the calcaneus, talus, scaphoid, first cuneiform, and first metatarsal. When a person stands, the foot is only a calcaneus tubercle.

1. The fifth metatarsal head lands on the ground in three places, and bears the weight of the whole body together.

According to normal human anatomy: the toes are anterior, the heel is posterior; The hallux side of the foot is internal, and the little toe side is external; The plantar surface of the foot is down, the back of the foot is up, and the plantar surface of the foot is also called the palmoplantar surface of the foot; The back of the foot is connected to the lower leg, and the ankle joint is formed between the foot and the lower leg. The hallux and other toes of the foot have medial, lateral, dorsal, underside, toe tip, toe base, etc.

The dorsal surface of the toe has four toes, and its underside is also called the metatarsol surface of the toe or the metasol planar surface of the toe. The underside of the foot is divided into three parts: the anterior part of the palmar plantar, the center of the foot, and the heel from front to back.
