Double osteotomies for structural correction of hallux abducto valgus
Abstract:
The authors discuss their procedure for performing osteotomies for correction of hallux abducto valgus. Their technique involves the use of a paper template which aids in establishing normal values according to the functional position in which they desire to place the joint. They outline their procedure for performing the closing abductory wedges of the base of the first metatarsal and the closing medial wedges of the head of the first metatarsal. After the correction has been completed, they apply a below-the-knee cast.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
