Abstract:
We developed a substitution technique for a sagittal band reconstruction for subluxation of the third extensor tendon at the metacarpophalangeal joint. Through this procedure, we attempted to supply a tether between the second and third extensor digitorum communis (EDC) tendons. A half-slip of the second EDC was interlaced to the third EDC tendon at the level of the third metacarpal head with the metacarpophalangeal joint in full flexion position; this ensured that the interlace of the graft serves as a direct stabilizer against ulnar subluxation. A key advantage of our procedure is the strong and reliable interlace of the graft that does not require postoperative immobilization and allows unprotected motion protocol.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
