During an amputation procedure, which structure is typically left intact to facilitate prosthetic fitting?
Muscles
Nerves
Tendons
Bone stump
The Correct Answer is D
During an amputation procedure, the bone stump is typically left intact to provide a stable base for prosthetic fitting. The muscles, nerves, and tendons are carefully dissected and secured to prevent complications and facilitate healing.
a. Muscles: While muscles are involved in the surgical procedure, they are typically resected to the appropriate level to accommodate the prosthetic device.
b. Nerves: Nerves are carefully dissected and secured during the amputation procedure to prevent neuromas and phantom limb pain but are not left intact for prosthetic fitting.
c. Tendons: Tendons are typically resected during the amputation procedure, and their positioning and attachment are crucial for proper wound closure and healing, but they are not left intact for prosthetic fitting.

Correct Answer is C
Explanation
Acute osteomyelitis is a severe bacterial infection of the bone that can lead to tissue damage and the spread of infection if not promptly treated. In some cases, when antibiotic therapy is not effective or the infection is severe, amputation may be considered to remove the infected bone and prevent further complications.
a. Severe joint pain: Severe joint pain may be caused by various conditions, but it is not an indication for amputation. Treatment for joint pain involves identifying and managing the underlying cause.
b. Chronic osteoporosis: Osteoporosis is a condition characterized by weakened bones, but it does not typically lead to amputation. Treatment for osteoporosis focuses on preventing fractures and improving bone density through medication and lifestyle modifications.
d. Muscle strain: Muscle strains are common injuries that do not require amputation. They can usually be managed with rest, ice, compression, and elevation (RICE) and physical therapy.
Correct Answer is A
Explanation
The primary purpose of positioning the residual limb in a flexed position after a below-the-knee amputation is to prevent contractures. Contractures are abnormal shortening and tightening of muscles and tendons, leading to restricted joint movement. Maintaining the limb in a flexed position helps prevent contractures and ensures optimal prosthetic fitting and functional outcomes.
b. To promote venous return: While positioning the limb in a flexed position may have some impact on venous return, it is not the primary purpose of this positioning. Elevating the limb on a pillow is more effective for promoting venous return.
c. To reduce edema: Keeping the residual limb elevated on a pillow is the preferred method for reducing edema in the immediate post-operative period, not positioning it in a flexed position.
d. To facilitate wound healing: Facilitating wound healing is not the primary purpose of positioning the residual limb in a flexed position. Proper wound care, dressing changes, and monitoring for signs of infection are essential for wound healing.
