The Lumbopelvic Hip Girdle
The second article of a two-part series on the lower kinetic chain.
The first article of this series discussed the structures of the foot, ankle and knee. This article will address the other area of the lower kinetic chain: the lumbopelvic hip girdle. You will learn how to assess the structures in this area, discover how the alignment of the...
The elbow is a “hinge” joint formed by the distal end of the humerus and the proximal ends of the radius and ulna bones. The elbow moves into flexion and extension. The trochlea and capitulum of the humerus articulate with the trochlear notch of the ulna and the radial head, respectively.
The specific articulations of the elbo...
The bones involved in ankle articulation include the tibia, fibula and talus. The tibia and fibula are the long bones of the lower leg; the fibula, a relatively thinner bone, is lateral to the tibia. These two bones are bound together by the ligaments and the interosseous membrane.
The spinal cord begins as an extension of the brain. It is surrounded by the bony vertebral column, which acts as a protective mechanism. Any information (sensory or motor) that the brain needs to relay to the body travels via the spinal cord.
