The greatest displacement of the meniscus is caused by external rotation, while internal rotation relaxes it. [1] During rotational movements of the tibia (with the knee flexed 90 degrees), the medial meniscus remains relatively fixed while the lateral part of the lateral meniscus is displaced across the tibial condyle below. [2]
As such, rotation and obliquity of the pelvis have been determined to be instrumental in producing more symmetric gait, even when the rotation itself is asymmetric between intact and impaired limbs. [18] Torso or trunk motion is also linked to amputee gait, specifically increasing upper-body ranges of motion with decreasing walking velocity. [19]
External rotation (or extorsion or lateral rotation) is an anatomical term of motion referring to rotation away from the center of the body. The external rotator muscles include: Muscles
Cylinder casts are orthopedic devices used to immobilize the arm or leg while leaving the surrounding joints free, providing focused stabilization to specific regions. In the arm, a cylinder cast typically extends from the upper arm to just above the wrist, stabilizing injuries like isolated humeral fractures or post-surgical repairs that do ...
Pronation at the forearm is a rotational movement at the radioulnar joint, or of the foot at the subtalar and talocalcaneonavicular joints. [ 11 ] [ 12 ] For the forearm, when standing in the anatomical position , pronation will move the palm of the hand from an anterior-facing position to a posterior-facing position without an associated ...

An example is compensating for a leg length discrepancy, equivalent to replacing a missing part of a limb. Another example is the replacement of the forefoot after a forefoot amputation. This treatment is often made from a combination of a prosthesis to replace the forefoot and an orthosis to replace the lost muscular function (ortho prosthesis).
External fixation is a surgical treatment wherein Kirschner pins and wires are inserted and affixed into bone and then exit the body to be attached to an external apparatus composed of rings and threaded rods — the Ilizarov apparatus, the Taylor Spatial Frame, and the Octopod External Fixator — which immobilises the damaged limb to facilitate healing.
