The anatomy of the extensor tendons of the fingers is very variable at the dorsum of the hand and the extensor apparatus of the fingers is very complex. Its precise knowledge is critical for the understanding of the physiopathology of their lesions and their treatment. Besides, lesions of the extensor tendons are frequent as they are subcutaneous in all their way, but specially at the fingers. At the dorsum of the wrist, the extensor tendons are distributed in six extensor compartments. At the fingers, the extrinsic extensor tendons find the intrinsic muscles of the hand (interossei and lumbricals) to form the complex extensor apparatus. Its main components are the central slip responsible for the extension of the PIP joint and the lateral bands that finally joint to form the terminal tendon responsible for the extension of the DIP joint. Besides, there are some connection fibres in the MCP and PIP joints, the sagittal bands and the transverse retinacular ligaments respectively, which connect the extensor apparatus to the anterior region of the finger, maintaining it in line with the finger axis over the convex side of the joints.
