Elbow Joint The elbow joint is a very complex hinge joint located between the distal end of the humerus in the upper region of the proximal ends of the ulna and radius. The elbow joint allows flexion and extension and rotation of the forearm and wrist. The range of motion of the elbow is limited due to the olecranon of the ulna so that elbow can only extend to 180 degrees. Like most synovial joints‚ a thin layer of articulating cartilage covers the ends of the bones to allow smooth movement.

What is is: Posterior Tibial Neuralgia‚ more commonly known as Tarsal Tunnel Syndrome is a painful condition caused by the entrapment or compression of the posterior tibial nerve. Anatomy: The posterior tibial nerve is a branch of the sciatic nerve and innervates the posterior compartment of the legs. As it continues down the leg‚ it passes posteriorly and inferiorly to the medial malleolus. It ends and branches off into sensory branches that innervate the sole of the foot. The tibial nerve travels

The two main processes involved in muscle contraction are cross-bridge cycling and the length-tension relationship‚ which normally function to maximize contraction in the muscle. Beginning with the activation of a motor unit‚ the ions flow from the motor unit towards the muscle fibers that it innervates by the motor neuron in the same way as a normal muscle would. However since the tissue is damaged‚ the force that is generated by these muscle fibers will not be as great‚ leaving the fibers less

Fractures of the foot can occur in many different ways but generally after a severe impact injury or gradually over time due to overuse or repetitive activity‚ over training or a training programme that has increased without giving enough time for build-up. Simply changing a training surface can result in injury e.g running on a track to running on a treadmill. The most common type of fracture is the stress fracture which is most common in runners or athletes who participate in sports that require
