Fibularis tertius – Distal part of the medial surface of fibula.Extensor digitorum longus muscle – Medial surface of fibula.Extensor hallucis longus muscle – Medial surface of fibula.Muscles originating from the fibula are listed below: Out of them, only the biceps femoris muscle gets inserted here, whereas the others originate from this bone. There are 9 muscles of the thigh and lower leg that remain attached to the fibula. Ankle joint: It is a hinged synovial joint formed by articulating the fibula, tibia, and talus bones. Distal tibiofibular joint: It is a slightly movable fibrous joint between the distal end of fibula and the fibular notch of tibia.ģ. Proximal tibiofibular joint: It is a plane synovial joint formed between the fibular head and lateral tibial condyle.Ģ. It is so prominent that its presence can be felt externally on the lateral side of the lower leg.ġ. The lateral surface gives rise to a bony projection on the distal end, known as the lateral malleolus. The posterior and medial borders form the posterior surface. Opposite to the medial surface, there is a lateral surface, guarded by posterior and anterior borders on both sides.ģ. The medial and anterior borders confine the medial surface.Ģ. As their name implies, the medial surface faces medially, the lateral surface faces laterally, and the posterior surface on the backside of the leg.ġ. The posterior border appears slightly rounded in the proximal part, but it becomes more prominent as it descends distally.Īs mentioned, these three borders mark the margin of three surfaces, medial, lateral, and posterior. The third border, i.e., the posterior border, runs along the back of the fibula. The fibrous interosseous membrane of the leg gets attached here.ģ. The medial border runs longitudinally on the medial side of the fibula. Then it diverges into two ridges surrounding the subcutaneous surface.Ģ. The anterior border extends from the fibular head to the lateral malleolus. The three borders give rise to three surfaces: lateral, medial, and posterior.ġ. It appears triangular in cross-section, having three borders: anterior, medial or interosseous, and posterior. The shaft or body makes up the major portion of the fibula. Just below the fibular head, there is a short bare region referred to as the neck. Lateral to the facet, there is an upward projection, known as the styloid process that extends superiorly from the head. It bears a circular articular facet for articulation with the lateral condyle of the tibia. The proximal end of the fibula features a slightly rounded enlargement known as its head. Each of its parts features several important bony landmarks. Like any other long bone, fibula also has two ends, proximal and distal parts, and an intervening shaft. Act as a lever during ankle movements, providing a range of motion during rotation of the ankle.Īnatomy – Parts of the Fibula with its Bony Landmarks.Provide stability to the lower limb and the ankle joint by combining with the tibia.In some cases, a bad splint may be worse than no splint at all! The most important advice: Practice splinting! Make your own splints and check the ones that nurses and technicians make for your patients. Remember the equinus position: Utilize this for Dancer’s fractures and Achilles ruptures.Mold the sleeve to the affected body part. Place the sleeve into lukewarm water, and remove excess water by sliding the sleeve between your index and long finger. How to avoid the mess of plaster: Before activation, layer plaster and place in a sleeve (stockinette).Makeshift Cuff and Collar: Use a disposable wrist restraint to create this splint.Ensure patients understand splint care: showering, weight bearing, unwrapping and re-wrapping if the splint feels too tight.Wrinkles in layers can cause friction, blisters, or infection. Protect the skin: Head from splint activation can cause burns.Though many facilities have nurses and patient care technicians who may assist with splint application, the ultimate responsibility for proper splint application lies with the physician. Understanding proper splinting technique is a critical skill for all emergency physicians.
