Abstract

Case-based cadaver dissection offers students unique opportunities to blend traditional anatomic knowledge acquisition with clinical reasoning. Twelve physical therapy students completed surveys centered on case-based dissections. Case-based cadaver dissections were defined in this study as multiple clinical vignettes that required students to use the accessible cadavers to solve clinically based problems. The results of the study provide preliminary evidence that students perceive case-based cadaver dissections as beneficial to their anatomy education and beneficial to the development of their clinical reasoning skills.

Appendices

Appendix A

Lab Report #1

A 54-year-old office executive went to the emergency department complaining of sudden chest and left arm pain. He is pale, diaphoretic, and reports feeling nauseated. Differential diagnoses include gastric and musculoskeletal etiologies, myocardial infarction, pericarditis, and myocarditis. He smokes one pack of cigarettes per day and has elevated blood pressure and cholesterol levels. He also has diabetes mellitus and a history of atherosclerosis and coronary artery disease.

  1. 1.

    Measure the width of the heart from the apex to the base.

  2. 2.

    Measure the width of the rib cage at the diaphragmatic edge of the heart.

  3. 3.

    Divide the rib cage width by the cardiac width.

  4. 4.

    Determine if the cardiac tissue is above or below the recommended 50% threshold.

  5. 5.

    Inspect the coronary arteries, sinuses, and veins. Detect any bypasses, blockages, or other obstructions.

  6. 6.

    Is a pacemaker or defibrillator present? What implications would those devices have on the case?

  7. 7.

    Inspect the pulmonary veins and arteries (if present). Detect any blockages and/or obstructions. What implications would blockages of these vessels have?

  8. 8.

    Inspect the atria and ventricles. Look at any abnormalities that may exist either in the valves, chordae tendineae, or papillary muscle. Report on any findings and potential implications for the case.

Lab Report #2

A physical therapist receives a referral for a patient with right shoulder pain. The patient is a 22-year-old male. The patient reports that his right shoulder pain started about 2 months ago and cannot recall any mechanism of injury. The patient reports that no specific motions increased the pain and he seems to only have pain around 3am. The pain usually wakes the patient up.

Past medical history is positive for the following: torn ACL in high school, wisdom tooth removal, and one ankle fracture. The patient also reports that he uses chewing tobacco and alcohol daily. The patient reports that he usually takes 3-4 Tylenol daily for pain control.

Objective exam revealed full PROM, full AROM, and 5/5 strength throughout the right shoulder.

  1. 1.

    View the visceral organs using a regional format. Chart the organs based on position within the viscera. Which organs would be most likely to refer pain to the right shoulder?

  2. 2.

    Organize the organs based on function and make a chart. Each organ has a different function. Start looking for patterns between the case presentation and the organ function chart.

  3. 3.

    Based on your findings, make a shortlist of three possible diagnoses. State why each of these diagnoses is plausible and why each diagnosis might be incorrect.

  4. 4.

    State your final diagnosis and why you think it is the correct diagnosis.

Lab Report #3

A 36-year-old patient presents in a physical therapy office with a diagnosis of sciatica. The patient states that he has the following symptoms: left-sided lower back pain that radiates down the posterior aspect of the left thigh to the knee.

When asked, the patient also states that he has noticed that he has difficulty holding his urine and pain during the night. The patient notes that the following activities increase symptoms: sitting for a long period of time, driving, rolling over in bed, and pain with prolonged walking.

  1. 1.

    Map out the lumbosacral plexus. Take note of the nerves and their root levels.

  2. 2.

    Look at the different symptoms and create a list of the possible nerves involved.

  3. 3.

    With the case presented, hypothesize whether what specific type of nerve or nerves may be involved (GVE, GSE, BE, etc.).

  4. 4.

    Create a list of 3 possible differential diagnoses. Explain why each could be a possibility and why each may be incorrect.

  5. 5.

    Hypothesize if the patient’s complaints of bladder changes are relevant to this case and potential pathology.

  6. 6.

    Arrive at a final diagnosis and defend your answer.
