How do Bimalleolar fractures happen?
How do Bimalleolar fractures happen?
The prefix “bi” means “two,” so a bimalleolar fracture is one that involves both the medial malleolus and the lateral malleolus. This type of fracture often happens as a result of the foot and ankle rolling inward, but it can also be caused by a trip or fall, or by a direct blow to the ankle.
What is the pathophysiology of fracture?
Fractures occur in patients with decreased bone strength and who experience an injury. Thus, the pathophysiology of fractures encompasses a multitude of factors that determine bone strength (bone mass, bone quality, age, skeletal geometry) and the frequency, nature, and effects of injuries (Figure 4.1).
What is a bimalleolar fracture of the ankle?
“Bimalleolar” means that two of the three parts or malleoli of the ankle are fractured. (Malleoli is plural for malleolus.) In most cases of bimalleolar fracture, the lateral malleolus and the medial malleolus are fractured and the ankle is not stable.
What is the usual mechanism for fractures of the ankle?
Ankle fractures can be caused by various modes of trauma, e.g., twisting, impact, and crush injuries. Falling, tripping, or sports activities may cause twisting forces through the ankle. Impact injuries may result from falling from a height with impaction of the distal tibia and fibula against the talus.
What type of fracture is a bimalleolar?
A bimalleolar fracture is a fracture of the lateral malleolus and the medial malleolus. This fracture is a bimodal distribution, most likely affects older women and young males and more than 60 years old. Surgery is the primary treatment of bimalleolar fracture because it is an unstable fracture.
How painful is bimalleolar fracture?
If you fractured your ankle, you will likely experience immediate, sharp pain and possible swelling. Additional symptoms include: Pain that spreads throughout the foot and up your leg, toward your knee. Intensifying pain if you try to bear weight on your foot.
What is the pathophysiology for a healing fracture?
Fracture healing begins with an injury‐induced hematoma and inflammation, which promotes the condensation of mesenchymal cells from the periosteum, endosteum, and bone marrow and their subsequent differentiation along chondrocyte and osteoblast lineages (Fig. 2).
What is the most common mechanism of injury for fractures?
The most prevalent mechanism of injury is external rotation which, together with abduction, accounts for approximately 75 per cent, of fractures at the ankle.
Where is a bimalleolar fracture?
“Bimalleolar” means that two of the three parts or malleoli of the ankle are broken. (Malleoli is plural for malleolus.) In most cases of bimalleolar fracture, the lateral malleolus and the medial malleolus are broken and the ankle is not stable.
What makes an ankle fracture unstable?
Explore Unstable Ankle Fractures In unstable ankle fractures, the ankle joint itself is displaced or can be displaced when it is subject to normal forces. Specifically, the lower bone of the ankle joint (the talus) is out of position or can be shifted out of position, leading to incongruity of the ankle joint.
What is a Syndesmotic injury?
A syndesmotic ankle sprain is an injury to one or more of the ligaments comprising the distal tibiofibular syndesmosis; it is often referred to as a “high ankle sprain.” Compared with the more common lateral ankle sprain, the high ankle sprain causes pain more proximally, just above the ankle joint, and is associated …
Do all Bimalleolar fractures need surgery?
There are different types of ankle fractures that can occur, and one of the more serious types is called a bimalleolar ankle fracture–an injury to both the inner and outer side of the ankle. Bimalleolar ankle fractures almost always require surgical treatment.
What are the signs of an ankle fracture?
Was there a noise when it happened? A sprain may occur silently,or in severe cases there may be a popping sound.
What does bimalleolar fracture mean?
Bimalleolar fracture is a type of ankle fracture, in which the inner and outer bony prominences at the lower end of the leg breaks or cracks. In this article, we deal with the causes, symptoms, diagnosis, treatment and recovery time of bimalleolar fracture. Knowing about the condition in detail can help in better management and faster recovery.
What is the recovery time for ankle fractures?
raise your ankle if possible
How long is recovery after a broken ankle?
Sitting on a chair,with both feet on the ground,place your uninjured foot on top of the recovering foot,and try to lift the foot underneath.
