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.

Triple tibial osteotomy not get crushed. The triple tibial osteotomy was developed by a New Zealand veterinary orthopaedic specialist, Dr. Warrick Bruce, while he was working in Adelaide, South Australia. By changing the geometry of the forces of gravity and muscle contractions that act on the stifle during weight-bearing, it aims to neutralise the shear force that causes the cranial movement of the tibia with respect to the femur. This shear force develops because the canine tibial plateau – the weight-bearing aspect of the joint – is sloped caudally (downwards towards the back of the joint)and there is an acute angle between the
