Chapter 8, Problem 2AYKA
Lauren has hurt her knee playing soccer. She explains that during the match, someone tackled her, hitting her on the lateral side of her knee. You notice during your examination that she has excessive range of motion in her knee; specifically, you are able to hyperextend her knee and anteriorly displace her tibia on her femur. Her tibia also displaces laterally on her femur. What has likely happened to her knee? Explain.

- A client fell on the ice a month ago and partially tore the distal end of his anterior cruciate ligament – ACL –(attaches the femur to the tibia) on his right leg/knee. A) What is the medical term (diagnosis) for this patient’s injury?arrow_forwardAfter viewing the MRI and talking with Elaine, Dr. Leutz strongly advised her to have reconstructive surgery on the ACL and to use conservative therapy on the partially torn medial collateral ligament. First, though, he wanted her to "pre-hab"-that is, take physical therapy for several weeks-in order to have the knee and leg in the best possible shape before the surgery. She was also instructed to use a more substantial brace. Dr. Leutz described the procedure: either a cadaver tendon OR the middle third of her patellar tendon would be removed and used to replace the ACL, which would be removed. Elaine opted to use her own tendon. Five weeks later, Elaine went in for surgery. She was given a drug used for conscious sedation as well as a general anesthetic. Through the arthroscope the surgeon noted significant injury to both the medial and lateral menisci, which he repaired with sutures and screws. The pieces of the torn ACL were removed. A superficial incision was made in the midline…arrow_forwardA 20-year-old man complained that he was unable to raise his right upper limb. He held it limply at his side with his forearm and hand pronated. During questioning by the physician, he stated that he had been thrown from his motorcycle approximately 2 weeks previously and that he had hit his shoulder against a tree. He also recalled that his neck felt sore shortly after the accident. Physical Examination: On examination it was found that the patient was unable to flex, abduct, or laterally rotate his arm. In addition, he lost flexion of the elbow joint. A lack of sensation was detected on the lateral surface of his arm and forearm. The physician requested radiographs of the cervical and pectoral girdle regions. Radiology Report: No fractures are seen in the cervical region, pectoral girdle, and proximal part of the humerus. Diagnosis: Injury of nerves derived from the brachial plexus. Using your anatomical knowledge of the nerve supply to the upper limb, discuss the…arrow_forward
- “Ron (he/his) is a 60-year-old man is experiencing right shoulder pain after falling off of a ladder 3 days ago while cleaning out the eavestrough gutters of his home. The man was brought to the hospital by his wife and is presenting with localized swelling, weakness, decreased range of motion, and has pain on palpation of the anterior right shoulder. His pain is increased when he tries to activate the shoulder by initiating external rotation and abduction. The man’s major complaint is that he is unable to comb his hair and brush his teeth without pain as he cannot maintain his arm in an elevated position for more than a few seconds. At the hospital, the doctor ordered an x-ray and gave him an injection of local anesthetic. The x-ray did not show any significant findings and the anesthetic relieved his pain but did not help with the weakness.” 3. From an anatomy point of view (not a medical school course!) : Propose a management plan for this man's rotator cuff tear. This should…arrow_forwardDuring her initial visit with the physical therapist, Mrs. Tanner presented with significant "foot drop" (the inability to dorsiflex the foot when taking a step). Mrs. Tanner was asked to perform a variety of movements with her right lower extremity. The therapist focused her attention on the prime movers and synergists of the hip, knee, and ankle. What are "prime movers" and "synergists"? Explain your answer.arrow_forwardFord hurt his knee in an auto accident when his knee was rammedinto the dashboard. The doctor tested the knee for ligament damageby having Ford sit on the edge of a table with his knee flexed at a90-degree angle. The doctor attempted to pull the tibia in an anteriordirection (anterior drawer test) and then tried to push the tibia in aposterior direction (posterior drawer test). Results of the anterior drawertest were normal, but unusual movement did occur during the posteriordrawer test. Explain the purpose of each test, and describe whichligament was damaged.arrow_forward
- Angus is an 18-year-old young adult, who is riding his skateboard in a city park. He is not wearing protective gear, including a helmet. When a friend distracts his attention, he runs head-on into a planter and is thrown over the planter box onto the concrete, landing on his left side. He immediately experiences pain in his left side, left wrist, and abdomen. His left wrist is angulated and obviously broken.A head-to-toe assessment demonstrates small, superficial scrapes on the patient's forehead and left cheek. His facial structures appear to be intact. Neurologically, he is normal, with a Glasgow Coma Scale (GCS) score of 14. He has no complaints of shortness of breath, and his chest wall shows no obvious external injury. An x-ray of his left wrist shows a comminuted fracture of his left radius and ulna.Angus is taken to the operating room for orthopaedic repair of his left wrist. After surgery, he is admitted to the orthopaedic floor with orders for pain medication as needed.Q1.…arrow_forwardJason is a 21-year-old university student presenting with pain in the back of his right thigh. The pain started yesterday during soccer game. Jason went to kick the ball and felt an immediate 'pull' in the back of his right upper thigh. He had to limp off the field and reported mild pain in his right hamstring muscles with most active movements involving knee flexion and extension. Jason can still walk around without too much discomfort. b) Suggest what type of injury Jason has sustained and discuss what structures are typically damaged in muscle strain?arrow_forwardA. Jeff was trying to toning his abdomen. However, he over-exerted himself and started to feel severe pain whenever he twisted his trunk (from left to right). If he simply did the sit-up without twisting his trunk, he did not feel the same degree of pain. Explain which muscle was damaged, and briefly explain why. B. When you open your mouth (such as when saying Ahh… at a physical exam ), which muscles are contracting, and which muscles are relaxing? How about when you are clenching your teeth or biting hard into a nut, which muscles are contracting, and which muscles are relaxing?arrow_forward
