NExt anatomy: Traction epiphysis
Traction epiphysis refers to a secondary ossification center in a long bone that is associated with the attachment of tendons or ligaments. These centers appear at sites where major tendons attach to the bone during growth. The traction epiphysis is subjected to the mechanical stresses produced by muscle contractions and serves as a point for the growth of the bone. An example is the tibial tuberosity, which is a traction epiphysis where the patellar ligament attaches to the tibia. The development and fusion of these traction epiphyses contribute to the overall growth and maturation of the long bones, particularly in areas where significant muscle forces are applied. Traction epiphyses are found in various long bones of the human body. Here are a few examples: 1. **Olecranon:** Located at the proximal end of the ulna, where the triceps brachii muscle attaches. 2. **Ischial Tuberosity:** The site where the hamstring muscles attach to the ischium. 3. **Greater Trochanter:** Found on the
