Where is the femur?

MedlinePlus says that the thigh bone is called the femur. The Real Academia Española dictionary places it more exactly: it is the bone that forms the skeleton of the thigh, articulating above with the iliac bone (hueso ilíaco) and below with the tibia and the kneecap (rótula). MedlinePlus describes the neck of the femur as the part just below the top of the bone.

Femur fractures

Hip fracture surgery is done to repair a break in the upper part of the thigh bone. For a femur fracture, MedlinePlus describes a surgery called open reduction and internal fixation (ORIF); in the most common version the surgeon inserts a rod or large nail into the center of the bone, and the rod helps support the bone until it heals. The surgeon may also put a plate next to the bone that is attached by screws.

What it means

The femur is the thigh bone. MedlinePlus states that the thigh bone is called the femur and, on another page, that the femur in the leg is also called the thigh bone. The Real Academia Española dictionary defines the Spanish word, fémur, as the bone that forms the skeleton of the thigh and that articulates above with the iliac bone and below with the tibia and the kneecap. Hip fracture surgery is done to repair a break in the upper part of the thigh bone, and in the most common surgery to repair a femur fracture the surgeon inserts a rod or large nail into the center of the bone. MedlinePlus says recovery from that repair most often takes 4 to 6 months.

Other Spanish termsWhere it is usedNote
hueso del musloGeneralName MedlinePlus en español uses for the same bone ("thigh bone") before giving the word fémur.

Fémur is spelled with a written accent on the é in Spanish; the English word has none. The Real Academia Española dictionary enters it as a masculine noun from Latin femur, so it takes el: el fémur, del fémur. MedlinePlus en español explains it with the name hueso del muslo (thigh bone): hip fracture surgery repairs a break in the upper part of the hueso del muslo, and "este hueso se denomina fémur."

For a femur fracture MedlinePlus en español writes fractura femoral, using the adjective femoral, and glosses fractura with ruptura (break). Other words from the same pages: cadera (hip), pierna (leg), varilla (rod), clavo (nail), placa (plate), tornillos (screws), muletas (crutches) and caminador (walker). The RAE definition adds muslo (thigh), tibia and rótula (kneecap).
