Tubercle (bone)
In the skeleton of humans and other animals, a tubercle, tuberosity or apophysis is a protrusion or eminence that serves as an attachment for skeletal muscles.
The higher, non-articular area is a rough elevation which gives attachment to the ligament of the tubercle.
[citation needed] The most prominent tubercle of the tibia, a leg bone which is more commonly known as the shinbone or shankbone, is the tibial tuberosity.
The tibial tuberosity is located on the tibia's anterior surface, distal to the medial condyle.
[citation needed] A trochanter is one of up to three tubercles of the femur: In the fifth metatarsal bone, the most proximal part of the bone is termed the "tuberosity", and the secondary ossification center that is normally present thereon in children is termed the "apophysis".
- Proximal diaphysis , typically stress fracture . [ 2 ] [ 3 ]
- Metaphysis : Jones fracture [ 4 ]
- Tuberosity : Pseudo-Jones fracture [ 5 ] ( avulsion fracture ). [ 5 ]
Normal anatomy:
- Apophysis: Normal at 10 - 16 years. [ 6 ]
- Os vesalianum , an accessory bone . [ 7 ]
