A 65-year-old patient presents with a chronic, non-healing ulcer on the lower leg. The ulcer is located around the malleoli, and the clinical examination suggests that the patient may be suffering from a gravitational ulcer, often associated with venous insufficiency. The healthcare provider needs to identify the specific area known as “Gaiter’s zone” where these ulcers are typically found.
Gaiter’s zone, a clinical finding in gravitational ulcers, is located around:
A. Malleoli
B. Toes
C. Knee
D. Calf
The Correct Answer is: A. Malleoli
Explanation:
– Malleoli (A): Gaiter’s zone refers to the area of the lower leg around the medial and lateral malleoli where gravitational ulcers (also known as venous stasis ulcers) commonly occur. This region is particularly affected by chronic venous insufficiency and poor blood circulation, leading to ulcers in this specific area.

Explanation of Incorrect Options:
– Toes (B): Ulcers on the toes are more commonly associated with peripheral arterial disease or diabetic foot ulcers, rather than gravitational ulcers.
– Knee (C): Ulcers around the knee are not characteristic of gravitational ulcers. They are less commonly associated with venous insufficiency.
– Calf (D): While venous ulcers can occur on the calf, Gaiter’s zone specifically refers to the area around the malleoli, not the entire calf.
In summary, Gaiter’s zone is specifically located around the malleoli, making option A the correct answer.
