Acromioclavicular Joint

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

Introduction One night a lady’s body was found dead in her apartment building. When the police came to collect the body as well as any evidence related to the crime they found many fibers including a red fiber found on the victim’s body. This red fiber was extremely interesting considering that close friends and family members of the victim stated that the victim hated red, and probably didn’t own anything of that color. From this we know that if the fiber is red then it does not belong to the lady. In addition, the door man stated that he did not see anybody enter the apartment building during the time of the killing, therefore we can conclude that the killer must live in the apartment building.

A, an unloaded knee. B, when valgus loading is applied, the medial collateral ligament becomes taut and lateral compression occurs. C, this compressive load, as well as the anterior force vector caused by quadriceps contraction, causes a displacement of the femur relative to the tibia where the lateral femoral condyle shifts posteriorly and the tibia translates anteriorly and rotates internally, resulting in ACL rupture. D, after the ACL is torn, the primary restraint to anterior translation of the tibia is gone. This causes the medial femoral condyle to also be displaced posteriorly, resulting in external rotation of the tibia. ( 63 )

The ACL originates from the medial and anterior aspect of the tibial plateau and runs superiorly, laterally, and posteriorly toward its insertion on the lateral femoral condyle. Together with the posterior cruciate ligament (PCL), the ACL guides the instantaneous center of rotation of the knee, therefore controlling joint kinematics. To a lesser degree, the ACL checks extension and hyperextension. The ACL is not as strong as the posterior cruciate ligament (PCL), and it is less strong at its femoral origin than at its tibial insertion. Muscles surrounding the knee joint contribute to knee stabilization during lower extremity movements.

The ACL works with the PCL (posterior cruciate ligament), which crosses over it to form an "X." Together, these two ligaments help keep the knee stable when rotating. The ACL keeps the shin bone in place and prevents it from moving too far forward and away from the knee and thigh bone. It prevents the shin bone

For the human joint anatomy project, our group decided to research and construct the elbow joint. The following is a report and summary of the project including roles taken, challenges faced, solutions derived, and ultimately, contribution and experiences of both partners.

Dr. Claes has received multiple awards associated with his job. He was the winner of the Biennial John Joyce award at the 9th Biennial International Society of arthroscopy knee surgery and orthopedic sports medicine. He is also the winner for the best paper in ligaments and biomechanics at the 16th European Society for sports

The Anterior Cruciate Ligament (ACL) is one of the most common knee injuries in female sports today. The ACL is a ligament that attaches the femur and tibia to the knee allowing the knee to bend while still being stable and supporting the whole body. Dr. Russel F. Warren, a physician for the New York Giants football team, explains, “The ACL prevents the shin bone (tibia) from moving too far forward on the thigh bone (femur) and keeps the knee from twisting inward excessively.” When athletes tear their ACL there is a greater chance that they have hurt or another ligament in their knee such as the LCL, MCL or Meniscus; which is cartilage that absorbs shock from the body’s pressure (MedlinePlus). The ACL is strong, but one wrong move could result

The anterior cruciate ligament (ACL) is one of the four main ligaments in the knee joint that connect it to the shin bone (tibia) and thigh bone (femur). It 's located deep within the joint, behind the kneecap (patella), above the shinbone, and below the thighbone. The ACL lies diagonally across the middle of the knee and plays a role in keeping the knee stable during movement. Partial tears of the ACL can occur, but are rare. Most ACL tears are either near-completes or complete tears. After experiencing an ACL tear, an athlete has a 15 times

The knee joint consists of four ligaments, two intra-capsular which are the ACL and the PCL and two extra-capsular ligaments including the MCL and LCL. The ACL is an extremely strong stabiliser which prevents anterior displacement of the knee. The ACL is a ligament and therefore connects one bone to another, the femur with the tibia. The ACLs origin is from the anterior intercondylar eminence of the tibia (home,2017) and the fibres pass upwards, backward and laterally inserting into the lateral condyle of the femur.

The Anterior Cruciate Ligament also known as the ACL is deemed the most commonly torn ligament in the knee and can result from both contact and noncontact injuries. Most Anterior Cruciate Ligament injuries result from an extreme force on the lateral side of the person’s knee causing a valgus force which pushes the knee inward (Kisner & Colby, 2012, pp. 802-803). This injury to the side of the knee can also cause a “Terrible Triad” injury which also injures both the medial meniscus and the medial collateral ligament (Kisner & Colby, 2012, p. 803). Our textbook further states that “the most common noncontact mechanism is a rotational mechanism in which the tibia is externally rotated on the planted foot….this mechanism can account for as many as 78% of all ACL injuries” (Kisner & Colby, 2012, p. 803). If the person does not seek medical help with this injury they are susceptible to also injuring the remaining support ligaments as well. Patients usually present with joint effusion; possibly 25 degrees of flexion, joint swelling if blood vessels are involved, limited ROM, stress pain and instability along with quads avoidance gait patterns (Kisner & Colby, 2011, p. 208)

A torn ACL is one of the most serious and common knee injuries. Many aspects play a role in the treatment and rehabilitation of this injury. This paper will discuss the anatomy of the knee, describe a torn ACL, and the rehabilitation.

(AGG) During the book the Giver Jonas’s relationships with people changed how he thought of the society.(BS-1) At the beginning of the book Jonas wanted to continue his friendships with people he was friends with before the ceremony of 12. He also wanted to fit into his family watching over the new child Gabriel.(BS-2) Once Jonas became the receiver of memories he started to question what was happening, to his society that he didn't know before and that the relationships he had were full of lies. (BS-3)

In this phase the athlete is standing in a neutral position holding the ball. The metatarsophalangeal and interphalangeal (great and lesser toes) are held at slight flexion pressed against the ground by an isometric contraction of the flexor halluces longus, flexor digitorum longus, flexor digitorum longus. The ankle is plantar flexed using an isometric contraction of the gastrocnemius and the soleus. The tibiofermoral (knee) joints are slightly flexed by a isomectric contraction of the quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). The acetabularfemoral (hip) joint is held at a postion of slight flexion through an isometric contraction of the biceps femoris, pectineus, iliacus, and the psoas. The intervertebral (lumbar) joint is extended by an isometric contraction using the erector spinae. The atlantooccipital (cervical spine) joint is flexed by an isometric contraction erector spinae. Both scapulothroracic (shoulder girdle) joint is protracted by an isometric contraction of the serratus anterior and pectoralis minor. The glenohumeral (shoulder) joint is at internal rotation by an isometric contraction using the pectoralis major, latissimus dorsi, teres major, and the subscapularius. The humeroulnar (elbow) joint is at 90 degrees of flexion by an isometric contraction using the biceps brachii, brachioradialis, and brachialis. The radiocarpal (wrist left and right)

The Law of Moses conveys not only God's authority and power over all of humans, but also his loving nature and grace for humanity, which is shown to them through his willingness to come down to the human's level, so that they may be pleasing in the sight of God. Within the book of Exodus, we find that God is fulfilling the Abrahamic covenant, by leading them out of captivity of the Egyptians. God is with them always, just as he promised. When the commandments were given to Moses, there was a slight disconnect between The first five and the second, which has much to say about God's character. The first five are about honoring, respecting your authority such as God. It will be extremely important to the Israelites to honor these, because ultimately
