The left metatarsophalangeal and interphalangeal (great and lesser toes) joints are held at slight flexion pressed against the ground by a concentric contraction of the flexor halluces longus, flexor digitorum longus, flexor digitorum longus. The left talocrural (ankle) is plantar flexed using a concentric contraction of the gastrocnemius and the soleus. The right talocrural (ankle) is plantar flexed by a concentric contraction of the tibialis anterior, extensor digitorum longus, peroneus tertius. The left tibiofermoral (knee) joints are being extended by a concentric contraction of the quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). The right metatarsophalangeal and interphalangeal (great and lesser toes) are being held plantar flexed due to an isometric contraction of the flexor halluces longus, flexor digtorum longus. The right tibiofermoral (knee) joints are flexed at a 90-degree angle by a concentric contraction of the biceps femoris, semitendinous, semimembranosus. During this phase the left acetabular fermoral (hip) joint is flexed due to an eccentric contraction of the rectus femoris, pectineus, iliacus, and psoas. The right acetabular fermoral (hip) joint is at slight extension due to a concentric contraction of the biceps femoris, semitendinosus, semimembranosus, and the gluteus

Baseball is America's pastime. Everyone in this country knows a person who plays the game and the struggles they face throughout their entire baseball endeavors. Baseball is an overhead throwing sport that requires countless amount of repetition in order to perfect the art of throwing a baseball with different spins and velocities. Because baseball has become a non-season based sport in this modern era, it has risen health risks to the elbows of athletes that play continuously. The Ulnar Collateral Ligament, commonly coined as the Tommy John Ligament, is the

In order to test the passive sufficiency of a bi-articular structure, such as a muscle, both joints which that structure crosses must first be identified. Additionally, the movements of those two joints which will constrain that structure must be identified. Next, one joint must be selected, and placed into the position that may constrain the structure. At the same time, the other joint must be placed in the position which will NOT put further strain on that structure. The selected joint must then be measured for its range of motion. Next, the same must be done with the selected joint, but in contrast, the other joint must be placed in the position which WILL further constrain the bi-articular structure. Once that has been done, the selected joint’s range of motion must be measured once more.

Dr. Frank Jobe developed a procedure for pitcher Tommy John (who the surgery was named after). With vivid research of the ligaments inside the medial elbow he developed a way to make the elbow back to normal strength or in some cases much more stronger. This surgery consisted of the new tendon being implanted and woven in a figure-eight pattern through holes

As Dr. Akizuki explains, "In order to get exposure to the joint you used to have to detach the entire flexor attachment [the muscles that flex the elbow--you can feel those muscles by feeling along the incision site]. You used to just fillet that open."

The world we are living in is age maturity of 65 at a rate of 10,000 per day. As people getting older, the body is breaking down and in of repair. Individuals are living longer and the technology to fix different part of the body is improving and allowing people to live a comfortable live. Moreover, a businesses have to take on the task of providing the material to help doctors facilitating their endeavors. Joint Ortho has taken on the challenge and has proven to be an expert in the field.

The surgeon may suggest doing an arthroscopy, just to make sure it’s not arthritis causing the pain. An arthroscopy is where an incision is made in your elbow and a small camera is inserted to see what is happening inside your elbow. However, an arthroscopy is not always necessary. The surgery begins with an incision on the medial (inside) side of the elbow. Then the tendon from another part of the patient’s body is inserted into the elbow. The new tendon is usually found in the person’s forearm, hamstring, knee, or foot. The procedure of replacing one tendon with another tendon from the same body is known as autograft. In order for the surgeon to see the problem they must split the flexor muscle and then reattach them after the procedure is over. The surgeon will drill two holes in the ulna and three holes at the end of the humerus. The tendon is threaded through the first two holes then through the triangular shaped holes at the end of the humerus. After the tendon is secured, sutures are placed at each end of the tendon. The surgeon uses the sutures to pull and bring the new tendon to the right amount of tightness. Then the sutures are tied together to hold the tendon in place. After the surgeon has completed all of these steps, the insertion is stitched back up. (EOrthopod). Once the surgical procedure is finished, the doctor will explain the recovery

As early as 2700BC in China, a form of manipulation, described by the Kung Fou Document was practiced. Centuries later, The Golden Mirror of Medicine had an illustration of a gravity traction technique, suggesting that the practice of spinal manipulation had continued. The patient was illustrated standing on two piles of tiles that were removed from under the patient as the practitioner applied force to the patient’s lumbar spine.

What structure passes through the region outlined by the yellow arrow and how does it contribute to the pain experienced in the anterior compartment of the arm by Bruce? (3 marks) The structure passing through the yellow arrow is the humerus. It contributes to the pain at the anterior compartment of the arm by the long head tendon of the biceps muscle grinding against the scapular muscle. This leads to the ongoing instability of the humerus giving Bruce a large chance of a subluxated humerus. The superior labrum will also grind up against his inflamed bursa which is why Bruce has decreased range of motion and lots of

The shoulder is a ball and socket joint which allows it a flexion and extension motion.

The ankle joint is a rolling joint that gains most of its stability from osseous and ligamentous structures. Congruence of distal articular surface of the tibia, fibula, and trochlear surface of the talus aids in even distribution of weight-bearing forces on the joint. Medial ligamentous structures, interosseous membrane, tibiofibular, lateral collateral ligaments, and tendinous structures assume static stabilization role of the ankle. (10,11,22).

Joints are vital for connecting bones together. This framework authorizes our bodies to capacity as one, comprehensively. Joints are the essential hotspot for delivering force and development; it gives backing to the body, and security to our milder organs. A portion of the principle joints in the body incorporate the Shoulders, elbows and knees; these all work together to finish individual assignments. In spite of the fact that, we have numerous joints there are numerous that are not as adaptable. There are a few that have parts to secure yet don't permit development, for example, our noggin bone. This current bone's part is haven of the cerebrum and sense organs. Without the utilization of joints, makes it simply difficult to have any exercises

The knee joint is formed by the articulation of the distal end of the femur and the proximal end of the tibia. The fibula is only involved to the extent that it serves as an attachment site for connective tissue. In this paper, the anatomy of the joint will be discussed.

The agonist muscles are triceps brachii (long, lateral, and medial heads), supinator, and anconeus. The antagonist muscles are the brachialis, biceps brachii, deltoid (anterior part), pectoralis major, and supraspinatus. It is composed of three bones: humerus, radius and ulna. The primary tendons are the biceps tendons (attaches biceps to radius) and triceps tendon (attaches the triceps to the ulna). The two main ligaments are the ulnar-collateral ligament (inside of the elbow) and lateral collateral ligament (outside of the
