How is a fibula fracture treated without surgery?
A fibula fracture is known as a lateral malleolus fracture. There are different levels at which that the fibula can be fractured. The level of the fracture may direct the treatment. You may not require surgery if your ankle is stable, meaning the fractured bone is not out of place or just barely out of place. A stress x-ray may be done to see if the ankle is stable. The type of treatment required may also be based on where the bone is fractured.
Several different methods are used for protecting the fracture while it heals. These range from a high-top tennis shoe to a short leg cast. Some physicians let patients put weight on their leg right away, while others have them wait for 6 weeks. You will see your physician regularly to repeat your ankle x-rays to make sure the fragments of your fracture have not moved out of place during the healing process.
How is a fibula fracture treated with surgery?
If the fracture is out of place or your ankle is unstable, your fracture may be treated with surgery. During this type of procedure, the bone fragments are first repositioned (reduced) into their normal alignment. They are held together with special screws and metal plates attached to the outer surface of the bone. In some cases, a screw or rod inside the bone may be used to keep the bone fragments together while they heal.
How is a medial malleolus fracture treated without surgery?
A medial malleolus fracture is a break in the tibia, at the inside of the lower leg. Fractures can occur at different levels of the medial malleolus. Medial malleolar fractures often occur with a fracture of the fibula (lateral malleolus), a fracture of the back of the tibia (posterior malleolus), or with an injury to the ankle ligaments.
If the fracture is not out of place or is a very low fracture with very small pieces, it can be treated without surgery. A stress x-ray may be done to see if the fracture and ankle are stable. The fracture may be treated with a short leg cast or a removable brace. Usually, you need to avoid putting weight on your leg for approximately 6 weeks. You will need to see your physician regularly for repeat x-rays to make sure the fracture does not change in position.
How is a medial malleolus treated with surgery?
If the fracture is out of place or the ankle is unstable, surgery may be recommended. In some cases, surgery may be considered even if the fracture is not out of place. This is done to reduce the risk of the fracture not healing (called a nonunion), and to allow you to start moving the ankle earlier.
A medial malleolus fracture can include impaction or indenting of the ankle joint. Impaction occurs when a force is so great it drives the end of one bone into another one. Repairing an impacted fracture may require bone grafting. This graft acts as a scaffolding for new bone to grow on, and may lower any later risk of developing arthritis. Depending on the fracture, the bone fragments may be fixed using screws, a plate and screws, or different wiring techniques.
Posterior Malleolus Fracture
What is a posterior malleolus fracture?
A posterior malleolus fracture is a fracture of the back of the tibia at the ankle joint.
In most cases of posterior malleolus fracture, the lateral malleolus (fibula) is also fractured.
This is because it shares ligament attachments with the posterior malleolus. There can also be a fracture of the medial malleolus.
Depending on how large the fractured piece is, the back of the ankle may be unstable. Some studies have shown that if the piece is bigger than 25% of the ankle joint, the ankle becomes unstable and should be treated with surgery.
It is important for a posterior malleolus fracture to be diagnosed and treated properly because if it is not, you are more likely to develop arthritis. The back of the tibia where the bone breaks is covered with cartilage. Cartilage is the smooth surface that lines a joint. If the fractured piece of bone is larger than about 25% of your ankle, and is out of place more than a couple of millimeters, the cartilage surface will not heal properly and the surface of the joint will not be smooth. This uneven surface typically leads to increased and uneven pressure on the joint surface, which leads to cartilage damage and the development of arthritis.
How is a posterior malleolus fracture treated without surgery?
If the fracture is not out place and the ankle is stable, it can be treated without surgery. Treatment may be with a short leg cast or a removable brace. Patients are typically advised not to put any weight on the ankle for 6 weeks.
How is a posterior malleolus fracture treated with surgery?
If the fracture is out of place or if the ankle is unstable, surgery may be offered. Different surgical options are available for treating posterior malleolar fractures. One option is to have screws placed from the front of the ankle to the back, or vice versa. Another option is to have a plate and screws placed along the back of the shin bone.
Bimalleolar Fractures and Bimalleolar Equivalent Fractures
What is a bimalleolar fractures or bimalleolar equivalent fracture?
"Bi" means two. "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.
A "bimalleolar equivalent" fracture means that in addition to one of the malleoli being fractured, the ligaments on the inside (medial) side of the ankle are injured. Usually, this means that the fibula is fractured along with injury to the medial ligaments, making the ankle unstable.
Can a bimalleolar or bimalleolar equivalent fracture be treated without surgery?
These injuries are considered unstable and surgery is usually recommended. Nonsurgical treatment might be considered if you have a condition that prevents surgery or if you usually do not walk. Immediate treatment typically includes a splint to immobilize the ankle until the swelling goes down. A short leg cast is then applied. Casts may be changed frequently as the swelling subsides in the ankle. You will need to see your physician regularly to repeat your x-rays to make sure your ankle remains stable. In most cases, weightbearing is not be allowed for 6 weeks. After 6 weeks, the ankle may be protected by a removable brace as it continues to heal.
How is a bimalleolar or bimalleolar equivalent fracture treated with surgery?
Surgical treatment is often recommended because these fractures make the ankle unstable. Lateral and medial malleolus fractures are treated with the same surgical techniques as written above for each fracture listed.
What are trimalleolar fractures?
"Tri" means three. Trimalleolar fractures means that all three malleoli of the ankle are fractured. These are unstable injuries and they can be associated with a dislocation.
Can trimalleolar fractures be treated without surgery?
These injuries are considered unstable and surgery is usually recommended. As with bimalleolar ankle fractures, nonsurgical treatment might be considered if you have a condition that prevents surgery or if you usually do not walk. Nonsurgical treatment is similar to bimalleolar fractures, as described above.
How are trimalleolar fractures treated with surgery?
Each fracture can be treated with the same surgical techniques as written above for each individual fracture.
How is a syndesmotic injury treated?
The syndesmosis joint is located between the tibia and fibula, and is held together by ligaments. A syndesmotic injury may be just to the ligament -- this is also known as high ankle sprain. Depending on how unstable the ankle is, these injuries can be treated without surgery. However, these sprains take longer to heal than the normal ankle sprain.
In many cases, a syndesmotic injury includes both a ligament sprain and one or more fractures. These are unstable injuries and they do very poorly without surgical treatment. Your physician may do a stress test x-ray to see whether the syndesmosis is injured.
How long does it take to recover from a fractured ankle?
Because there are so many types of injuries, there is also a wide range of how people heal after their injury. It takes at least 6 weeks for the fractured bones to heal. It may take longer for the involved ligaments and tendons to heal. Your doctor will monitor the bone healing with repeated x-rays. This is typically done more often during the first 6 weeks if surgery is not chosen.
