One of the most common deformities of the feet is the claw deformity of the toes. The causes of this deformity can be from purely genetic, sometimes caused by inadequate footwear or by biomechanical alterations in the balance of flexor and extensor forces of the tendons and muscles of the feet.
The consequences of this deformity are not only aesthetic, but also the appearance of painful corns in the knots of the toes (calluses) at the tips of the fingers and deformation by thickening of the nails. The correct diagnosis of the cause of this deformity will help in the choice of the most
appropriate surgical technique for its solution.
As biomechanical alterations we can include, cavus foot, Hallux Valgus, Abductus (bunion), functional equine foot, metartarsal formula alterations. Deformities acquired with biomechanical
origin can be divided into two types:
- The Static ones, being the use of the inadequate shoe the most important factor.
- The Dynamic, which are the muscular imbalances, biomechanical alterations.
The most common sign and symptom of claw toe is the appearance of helomas, commonly called callus and pain in the same, which can be located in the dorsal area of the toe, due to friction and pressure against the shoe or in the yolk of the said due to the attempt to want the toe to cling to the ground, to seek stability.
Another common symptom is due to the fact that the toe shrinks, rests less on the floor and begins to produce pain in the head of the corresponding metatarsal, this phenomenon is due to the fact that the elevated toe does not distribute its weight.
