Abstract:
Few studies have investigated the vascular anatomy of the trapeziometacarpal (TM) joint of the thumb. The aim of our study was to describe the supplying arteries of the trapezium and the TM joint since this knowledge is essential for trapezium osteotomies. Ten anatomical dissections in ten different cadavers using two different techniques (four macerations, six classic dissections) were performed. The arteries of the TM joint originated from the radial artery and the princeps pollicis artery. Four important branches were identified. The arteries formed a vascular network around the joint. The dorsoradial surface of the joint contained the richest arterial network. These findings present an important consideration when performing an osteotomy of the trapezium.

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.
