Valgus deformity of the ankle joint: pathogenesis of fibular shortening
Abstract:
An abnormal shortening of the fibula, leading to a valgus deformity of the ankle joint, is a common finding in the paralytic ankle. This article analyzes 173 ankles in which shortened fibulae were present. Analysis of several factors that interfere with fibular growth showed that soleus strength and anatomical continuity of the fibula are important factors in the normal fibular growth. Any factor that interferes with the normal balance of forces at the distal fibula physis can cause an abnormal shortening of the fibula and lead to valgus deformity of the ankle.

Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
