  Metatarsus - Wikipedia, the free encyclopedia
Its plantar surface is grooved antero-posteriorly for the passage of the flexor tendons, and marked on either side by an articular eminence continuous with the terminal articular surface.
Its proximal articular surface is of large size and kidney-shaped; its circumference is grooved, for the tarsometatarsal ligaments, and medially gives insertion to part of the tendon of the Tibialis anterior; its plantar angle presents a rough oval prominence for the insertion of the tendon of the Peronæus longus.
A fifth facet is occasionally present for articulation with the first metatarsal; it is oval in shape, and is situated on the medial side of the body near the base.

 Fluid filled insole with metatarsal pad - Patent 6178663
The metatarsal pads 180 are substantially equally spaced transversely from the imaginary longitudinal centerline of each other, and spaced from the medial and lateral margins of the bladder.
The metatarsal pads 180 are arranged in a shape that laterally, medially, transversely and longitudinally matches the anatomical structure of the proximal forefoot region, the shape being for example, but not limited to, an arc, a semicircle, or a trapezoid, the convex side of the shape facing in a distal direction.
The metatarsal pads 80,180 are formed by welding the upper bladder layer 12 to the lower bladder layer 14 circumferentially around the pads 80,180 to form a barrier 82,182.

 Foot and Ankle Conditions: Fractures of the Metatarsals
The first metatarsal is the most important and fractures of the first metatarsal usually require surgery.
Injuries to the metatarsals are sustained in many different ways ranging from minor twisting to falls and injuries sustained when heavy objects fall on the foot and literally crush the metatarsals.
Fractures of the fifth metatarsal are quite varied, and the treatment is determined according to the specific location of the fracture in this bone.

 Brachymetatarsia - Overview, Causes, Physiology & Treatment - podiatrychannel
Brachymetatarsia is a condition in which one of the five long bones of the foot (the metatarsals) is abnormally short, causing a short toe.
In this procedure, the short metatarsal is usually cut and a piece of bone is grafted between the two ends.
In this case, the two metatarsals flanking it may be shortened slightly to correct the arc of the toes and restore the foot's ability to transfer weight sequentially.

 Metatarsal arch supports for treating a dropped metatarsal head or arch
The metatarsal bones are the long bones that extend down from the ankle to the base of the toes.
When the metatarsal arch falls it puts excessive and uneven pressures on the protective fat pads that can cause them to shift and move away from the points of pressure.
A metatarsal arch support pad helps by lifting the metatarsal arch and applying pressure to encourage the return of the natural fat pad to the pressure point areas.

The diagnosis of metatarsal stress fracture is often made clinically when the athlete complains of bony pain usually accompanied with specific soft tissue swelling.
All of the proximal shaft fractures of the fifth metatarsal occur at the metaphyseal-diaphyseal junction which is away from the end of the bone where the avulsion fracture occurs.
The study of fifth metatarsal stress fracture prevention from a biomechanical perspective is fairly new.

 The Physician and Sportsmedicine: Fractures of the Fifth Metatarsal
In fifth metatarsal fractures, correctly identifying the fracture type is essential for permitting the earliest possible return to sports.
The cortex of the fifth metatarsal thickens considerably and the medullary canal narrows at the junction of the proximal metaphysis and diaphysis (figure B), marking a transition from mostly cancellous to relatively avascular cortical bone.
The blood supply to this part of the metatarsal, surrounded as it is by the soft tissues of the intermetatarsal and plantar areas, is quite good, and healing is very predictable.

 Metatarsal Strains Are Sufficient to Cause Fatigue Fracture During Cyclic Overloading
Simultaneous in vivo axial strains were measured at the mid diaphysis of the second metatarsal and the tibia in two subjects.
Peak axial metatarsal compression strains and strain rates were significantly higher than those of the tibia during treadmill walking and jogging both barefoot and with running shoes and during simple calisthenics.
Compression and tension strains in the metatarsus unlike those of the tibia may be sufficiently high even during moderate exertional activities to cause fatigue failure of bone secondary to the number of loading cycles without an intermediate bone remodeling response.

 Sport shoe with metatarsal cradle and drag toe - Patent 4914838
Accordingly, the likelihood that the athlete will suffer hyperflexure of the great toe metatarsal joint or "turf toe" is minimized even though the flexure of this portion of the shoe has been increased by the provision of the grooved metatarsal cradle 54.
As is apparent, then, the ridged and grooved configuration of the main sole member of the present invention minimizes the likelihood of metatarsal bruising due to driving spikes and increases comfort of the wearer and, further, minimizes the likelihood of hyperflexure of the great toe metatarsal joint.
Furthermore, because the drag toe element terminates rearwardly in the region of the metatarsal cradle, the reinforcement provided by the drag toe element does not reduce the flexibility of the shoe sole and thus does not reduce the efficacy of the metatarsal cradle.
