Q. Is the tibia proximal to the fibula?
The tibia is located in the lower leg medial to the fibula, distal to the femur and proximal to the talus of the foot. It is widest at its proximal end near the femur, where it forms the distal end of the knee joint before tapering along its length to a much narrower bone at the ankle joint.
Q. What is proximal to the fibula?
The proximal (top) end of the fibula is articulated with the lateral condyle of the tibia, just below the knee. That is called the proximal tibiofibular joint.

Q. What is proximal to the tibia?
Three bones meet to form the knee joint: the femur (thighbone), tibia (shinbone), and patella (kneecap). (Left) The proximal tibia is the upper portion of the bone, closest to the knee. (Right) Ligaments connect the femur to the tibia and fibula (kneecap not shown).
Q. What muscles attach to the tibia and fibula?
Muscle attachments
| Tibialis anterior | Lateral surface of tibia, Interosseous membrane |
|---|---|
| Soleus | Soleal line, Head of fibula, Posterior border of fibula |
| Tibialis posterior | Posterior surface of tibia, Posterior surface of fibula, Interosseous membrane |
| Flexor digitorum longus | Posterior surface of tibia |
Q. What muscle attaches to the tibia?
Tibialis anterior muscle
The Tibialis anterior muscle gets attach on the shaft of the tibia. It originates from the upper 2/3rd area of lateral surface of the shaft. The primary action of tibialis anterior is dorsiflexion and inversion of the foot.
Q. Which muscle originates at the proximal shaft of the tibia?
Soleus is flat muscle, deep to the gastrocnemius and originates at the head of the head of the fibula. It as well inserts into the calcaneal tendon and is innervated by the sciatic nerve (S1-S2). Tibialis Posterior originates on the proximal 2/3 of tibia and fibula and inserts onto the medial cuneiform and navicular.
Q. What ligament attaches to the fibula?
The lateral (fibular) collateral ligament attaches to the lateral side of the fibular head. This ligament provides knee stability.
Q. Is tibia medial or lateral?
The tibia is the larger, weight-bearing bone located on the medial side of the leg, and the fibula is the thin bone of the lateral leg.
Q. Which muscles attach to the tibia?
Muscle attachments
| Muscle | Direction | Attachment |
|---|---|---|
| Tibialis anterior muscle | Origin | Lateral side of the tibia |
| Extensor digitorum longus muscle | Origin | Lateral condyle |
| Soleus muscle | Origin | Posterior side of the tibia under the soleal line |
| Flexor digitorum longus muscle | Origin | Posterior side of the tibia under the soleal line |
Q. Which muscle inserts onto the medial surface of the proximal tibia?
Muscles. The Semimembranosus muscle originates from the ischial tuberosity and gets insert on the medial condyle of tibia.
Q. Where is the articulation site of the tibia located?
The articulation site on the tibia is found on the lateral side of its proximal part, while the fibula participates with the medial surface of its head. This joint is reinforced by the anterior and posterior ligaments of fibular head.
Q. What are the muscles that attach to the tibia?
The muscles of the lateral leg compartment attach to the fibula. Muscles that insert onto the tibia are the: sartorius, gracilis, quadriceps femoris, semimembranosus, semitendinosus, and popliteus muscles.
Q. Is the proximal fibula part of the leg?
The proximal fibula is the part of the bone that lives just below the knee joint on the outside. It’s attached to the leg bone (tibia) via strong ligaments and there is a small joint here.
Q. How are the tibia and fibulas bound together?
The tibia and fibula are bound together at this spot by a thickening of interosseous membrane in the inferior/distal tibiofibular joint. The anterior surface is smooth and covered by the tendons of the extensor leg muscles. Its lower margin features a rough depression for the attachment of the articular capsule of the ankle joint.
