The metatarsals are five long bones located in the foot, positioned between the tarsal bones of the ankle and the phalanges (toe bones). They form the instep and arch of the foot, playing a crucial role in weight-bearing, locomotion, and balance. Each metatarsal consists of a base (proximal end), a shaft (body), and a head (distal end) that articulates with the corresponding toe. Their structural integrity and alignment are essential for proper foot function, and injury to these bones can significantly impair mobility. metatarsal fractures are among the most common foot injuries, often resulting from impact or overuse.
Metatarsal meaning with examples
- During a marathon, a runner experienced a stress fracture in their second metatarsal due to repetitive impact and excessive mileage, leading to significant pain and a temporary halt to their training. This common injury impacts athletes. Proper footwear and careful training regimes are essential to preventing metatarsal injuries.
- The podiatrist examined the patient, noting tenderness and swelling around the fifth metatarsal. Based on the clinical examination, the metatarsal's position was identified as a result of an acute injury, and an X-ray confirmed a fracture, requiring immobilization in a cast for optimal healing and recovery.
- A ballet dancer suffered a Lisfranc injury, involving damage to the ligaments and bones of the midfoot, including the metatarsals. The severe nature of this injury required surgery to stabilize the metatarsal bones and restore the integrity of the foot's supporting structure and restore mobility.
- The biomechanics study focused on the loading patterns of the metatarsals during walking and running. Sophisticated pressure sensors measured the forces exerted on each metatarsal during different phases of gait analysis, to identify possible stress concentration zones that might predispose individuals to metatarsal injuries
