The interosseous membrane of the leg (middle tibiofibular ligament) extends between the interosseous crests of the tibia and fibula, helps stabilize the Tib-Fib relationship and separates the muscles on the front from those on the back of the leg.
X-ray, CT, or MRI scans can be used to diagnose the extent of the Maisonneuve fracture's damage and determine whether it is a simple or comminution fracture. [8] During diagnosis, a supination-external rotation pattern of injury may also be concluded if there is an isolated fracture of the posterior tubercle of the tibia. [9]
The inferior tibiofibular joint, also known as the distal tibiofibular joint (tibiofibular syndesmosis), is formed by the rough, convex surface of the medial side of the distal end of the fibula, and a rough concave surface on the lateral side of the tibia.
Tuberculosis creates cavities visible in x-rays like this one in the patient's right upper lobe.. A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary.
A tib-fib fracture is a fracture of both the tibia and fibula of the same leg in the same incident. In 78% of cases, a fracture of the fibula is associated with a tibial fracture. [6] Since the fibula is smaller and weaker than the tibia, a force strong enough to fracture the tibia often fractures the fibula as well. Types include:
The superior tibiofibular articulation is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. The inferior tibiofibular articulation (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the lower end of the fibula, and a rough concave surface on the lateral side of the tibia.
The mortise view is an AP x-ray taken with the ankle internally rotated 15-20 degrees since the foot is naturally externally rotated relative to the ankle. [9] In addition to these views, a full-length view of the tibia and fibula may be necessary to evaluate for injuries to the proximal fibula associated with Maisonneuve fractures .
