In the United States, there are usually between 100,000 and 200,000 Anterior Cruciate Ligament (ACL) ruptures per year. (Osborne. M, 2012) (Why do females injure their knees four to six times more than men…and what can you do about it?) (ucdenver.edu) An ACL injury is the most common injury in female athletes. Female athletes are more prone to having an ACL injury because of the lack of muscle strength and control of their (Chang. W, 2014; Joseph et al., 2014). This injury can lead to…

The thesis I have chosen to write about on a commonly held misconception is that cracking your knuckles will give you arthritis. I feel that everyone has, at some point in their lives heard the phrase “cracking your joints will give you arthritis”, even now that this misconception has been proven false many people still say this or believe it. Joint cracking can arise from the negative pressure pulling nitrogen gas into the joint, the sound can also arise from tendons snapping over tissues due…

Skeletal muscle is a highly specialized, post-mitotic tissue that must withstand chronic mechanical and physiological stress throughout life to maintain proper contractile function. Muscle damage or disease leads to progressive weakness and disability, and manifests in more than 100 different human disorders, including DMD, the most common X-linked genetic disorder in humans, and BMD. Current treatment options for muscular dystrophies are disappointingly limited and focus mainly on managing…

An 18-year-old male lacrosse player presents to the clinic for evaluation of left knee pain. He states that he stepped awkwardly with his cleat while taking a shot and had twisted the knee. He had immediate pain, but was able to bear weight afterwards. There was no swelling initially, but the following morning he noticed swelling of the knee. He reports that the knee has an occasional “catching” sensation but does not get stuck. On exam, he has a moderate effusion. He can perform a straight-leg…

adduction. Standing, where the fixed point is at the insertion on the femur, contraction will rotate the pelvis anteriorly[17]. 2.2.2 Psoas This muscle is only muscle group in human body with direct attachment to the spine, the pelvis and the femur. Therefore it has potential to influence, and influenced by movement at both of the spine and hip joints[18]. 2.2.3 Gluteal maximus muscle: superficial group The gluteus maximus muscle is the one of the largest muscle in the gluteal region and…

Have you ever gone to the doctor and ended up needing to get an MRI? If you have, did you know what it was or what it was meant to do? If you knew what it was for, you probably didn’t know the science behind how it worked. MRI stands for magnetic resonance imaging. Well an MRI is used for taking pictures to diagnose you. It is used on your chest, abdomen and pelvis. So pregnant women doctors might do a body MRI to safely monitor the baby. The MRI has a strong magnetic field. Which can be…

An 10X12 IR was used to produce the image and the SID was set at 40”. The Right Phantom foot was placed in the center of the IR. The CR was aligned perpendicular to IR to medial malleoli. A 4-sided collimation was created that included outer margins of the foot and ankle. A 68kVp, a 3.2mAs and a small FS was selected. The right marker was placed in IR. PACER Patient in a lateral recumbent position, affected side down. Flex affected limb 45°. Center and align ankle joint to CR. The plantar…

What is Plica syndrome? It is an irritation to the synovial membrane in the knee. This irritation is the result of repetitive friction to the tissue. Repetitive friction is due to abnormal forces at the knee, most likely in the kneecap and surrounding musculature, or may be caused by muscular weaknesses or structural abnormalities at the hip or foot, which place increased tension on the knee. “Plica syndrome can also be caused or made worse by increased activities. In some cases, a direct hit…

1. INTRODUCTION OSHA defines musculoskeletal disorders as “Injuries and disorders of the muscles, nerves, tendons, ligaments, joints, cartilage, and spinal disk”. According to OSHA, the MSDs listed as: Carpel tunnel, Rotator cuff syndrome, De Quervain, Trigger finder, tarsal syndrome, Sciatica, Epicondylites, and Tendonitis. Most of the work related MSD’s are developed over time and are caused by the work itself or the working environment of the employees. These are also possible to occur from…

Abstract: Dens evaginatus is an uncommon developmental anomaly of human dentition characterized by the presence of tubercle on the occlusal surface of mandibular premolars and lingual surface of anterior teeth. Due to occlusal trauma this tubercle tends to fracture thus exposing the pathway to the pulp chamber of teeth. This case report is about the presentation of dens evaginatus in mandibular premolars bilaterally, among them tooth 44 was associated with chronic apical periodontitis. Fractured…
