ABSTRACT

The close neighboring of the distal interphalangeal joint with the most proximal part of the matrix is of major importance in surgical anatomy, especially when performing a complete resection of the nail apparatus for a malignant process with wide margins. In pathology, the complex formed by the distal interphalangeal joint and the matrix is considered nowadays as an enthesis, explaining the propagation of some inflammatory diseases (psoriasis) from the joint to the matrix.
