Tuberosity of the First Metatarsal Bone

The tuberosity of the first metatarsal bone (t. ossis metatarsi I, PNA, BNA, JNA) is a small convexity on the lateral surface of the head of the first metatarsal bone. It is formed by the extensor digitorum longus and extensor digitorum longus tendons that pass through this area.

The tuberosity of the first metatarsal bone plays an important role in maintaining stability and balance when walking. It helps keep the foot in the correct position and ensures its stability. In addition, the tuberosity of the first metatarsal bone is involved in transmitting force from the foot to the ankle joint, which allows the leg to work effectively when walking and running.

However, in some people, the first metatarsal tuberosity may be enlarged or shaped differently, which can lead to various health problems such as foot pain, foot deformities, and even gait disturbances.

Various methods are used to treat first metatarsal tuberosity, including conservative treatment, surgery, and physical therapy. Conservative treatment includes the use of orthotics, massage, stretching exercises and other methods aimed at improving the functionality of the foot. Surgery may be required if the foot is severely deformed or if conservative methods do not produce the desired results.

It is important to remember that the tuberosity of the first metatarsal bone is a normal anatomical feature of the foot, and its increase is not always a sign of disease. However, if you are experiencing pain or discomfort in your foot due to bunion, you should see a doctor for diagnosis and treatment.

Tuberosity of the first metatarsal bone (cuneus metatarsalis (i) or often incorrectly referred to as cunea metatarsalia I) is one of the most common pathological processes of the foot skeleton. The incidence ranges from 4 to 16% depending on race. In white Americans it occurs in 12%. Causes include injuries, sprains and nutritional disorders. Inflammatory processes cause more problems on both sides. Men get sick twice as often as women. Often the problem goes undetected because it is not always visible beyond the line of sight and it can be difficult for patients to determine exactly where
