On Spanish site, the asker chose two terms:
orthopedics and podiatry

Another answerer was orthopodiatry.
As you can see, both podiatrists and orthopedists perform many of the same foot and ankle procedures. Both are highly trained and qualified to treat foot and ankle conditions both surgically and non-surgically. The only discernible difference between them is that an orthopedist manages parts of the foot and ankle that pertain to the bones, soft tissues and joints, while a podiatrist manages the same areas, but also the biomechanics and dermatology of the foot and ankle. For instance, a podiatrist is often an integral care provider for people with diabetes who have serious concerns about foot health

The main difference lies in the body systems they treat. Orthopedic surgeons are concerned with bones, muscles, ligaments and joints throughout the body. They are bone and joint doctors and surgeons. Podiatrists are foot and ankle doctors and surgeons. As such, there are overlaps between the two. Both are concerned with bones, muscles, ligaments and joints in the foot.

Outside of this, orthopedic surgeons are concerned with other areas of the body, including knees, hips, spine. Podiatrists are concerned with other organ systems in the foot and ankle, including the skin, blood vessels and nerves. Podiatrists are the orthopedic surgeons, plastic surgeons, neurosurgeons, dermatologists of the foot and ankle.

I think that orthopodiatry encompasses both specialties.
