Tarso-metatarsal amputation is k/a?
**Core Concept**
Tarso-metatarsal amputation refers to a surgical procedure that involves the removal of the foot's midsection, specifically the tarsal bones and the metatarsal bones. This type of amputation is typically performed in cases of severe trauma, infection, or peripheral vascular disease that has resulted in significant tissue loss.
**Why the Correct Answer is Right**
The correct answer is related to the specific type of amputation that involves the removal of the tarsal and metatarsal bones. This procedure is also known as a Chopart's amputation, which is named after the French surgeon Étienne-Henri-Hippolyte Maindonneau de Chopart who first described it in 1833. Chopart's amputation is performed at the level of the midfoot, resulting in the loss of the tarsal and metatarsal bones, but preserving the toes and the heel.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe a type of amputation that involves the removal of the tarsal and metatarsal bones. A Lisfranc amputation, for example, is a different type of midfoot amputation that involves the removal of the metatarsal bones, but not the tarsal bones.
**Option B:** This option is incorrect because it is not a recognized term in the field of surgery or orthopedics. While there are various types of amputations, this option does not accurately describe a specific procedure.
**Option C:** This option is incorrect because it is not related to the specific type of amputation that involves the removal of the tarsal and metatarsal bones. A transmetatarsal amputation, for example, involves the removal of the metatarsal bones, but not the tarsal bones.
**Option D:** This option is incorrect because it is not a recognized term in the field of surgery or orthopedics. While there are various types of amputations, this option does not accurately describe a specific procedure.
**Clinical Pearl / High-Yield Fact**
It is essential for surgeons and orthopedic specialists to understand the different types of amputations and their indications to provide the best possible care for patients with severe foot injuries or conditions. A thorough understanding of the anatomy and the specific procedures involved is crucial for optimal patient outcomes.
**Correct Answer:** C. Chopart's amputation
