Scenario/Summary
A 19-year-old male patient’s arm was severed at the distal forearm while working with a machine in his workplace. Both the limb and the patient was brought to the ER. When the severed limb was examined, it was noted that the tissue only received minor crush injuries at the site of amputation (see figure 1). After a long and arduous surgery reconnecting the muscles, nerves and blood supply the arm was replanted.
After years of therapy, the patient’s limb was salvaged with most functionality and sensitivity returned. Although very satisfied that the limb wasn’t lost, the patient notes that the functionality hasn’t been the same. The deformities to the limb at the site of amputation are also notable (see figure 2).
Deliverables
Answer the following questions based on the scenario and article above and save your responses in a Microsoft Word document. Provide a scholarly resource in APA format to support your answers.
1. Name the muscles severed during the amputation event.
2. If the patient were no longer to properly pronate his arm, which muscle do you think has been compromised?
3. In general, a patient with a severed limb has a smaller window of time for successful replantation when compared with finger replantation surgery. This is in part due to the difference in tissue composition of the two anatomical structures. What does this say about the metabolic demands for muscles, cartilage and bone? Why do you suppose that is?
4. What tissue type can be found bridging the two halves of the once severed muscle bellies? Why? (Hint: How do muscles grow, hyperplasia or hypertrophy?)
