Hemideina ricta The thorax contains the front, middle and hind legs of the weta, each leg is made up of six segments; the coxa, the trochanter, the femur, the tibia, the tarsus and the pretarsus. The ear of the weta can be found at the top of the tibia near the knee joint of the front legs. The tibia of the hind legs are covered in spines, that can be rubbed against the stridulatory ridges on the side of the body to produce a sound, these can also be used as a defence mechanism against predators.

Femur of these compartments has its own blood and nerve supply, and contains a different group of muscles. These compartments are named the anterior, medial and posterior fascial compartments. A femoral fracture that involves the femoral head, femoral neck or the shaft of the femur immediately below the lesser trochanter may be classified as a hip fracture, especially when associated with osteoporosis. Femur fractures can be managed in a pre-hospital setting with the use of a traction splint. In primitive tetrapods, the main points of muscle attachment along the femur are the internal trochanter and third trochanter, and a ridge along
