Question

What two muscles lie on the posterior aspect of the interosseous membrane and tibia in the lower leg, and must be elevated during a posterolateral approach to the tibia for treating a nonunion?

Answer 1

The soleus and flexor hallucis longus muscles lay on the posterior aspect of the interosseous membrane and must be elevated in a posterolateral tibial approach for a nonunion.

Step-by-step explanation:

The two muscles that lie on the posterior aspect of the interosseous membrane and tibia in the lower leg, which must be elevated during a posterolateral approach to the tibia for treating a nonunion, are the soleus and the flexor hallucis longus. These muscles are key anatomical structures in surgical procedures involving the lower leg, particularly when accessing the tibia.

In the context of the provided information, these muscles are part of the posterior compartment which also includes the gastrocnemius and plantaris muscles, but it is the soleus and flexor hallucis longus that are in immediate relation to the interosseous membrane and the posterior border of the tibia.

The two muscles that lie on the posterior aspect of the interosseous membrane and tibia in the lower leg and must be elevated during a posterolateral approach to the tibia for treating a nonunion are the flexor digitorum longus and the tibialis posterior muscles.

Answer 2

During a posterolateral approach to the tibia for treating a nonunion, two muscles that lie on the posterior aspect of the interosseous membrane and tibia in the lower leg must be elevated. These muscles are tibialis posterior and flexor digitorum longus 1. The tibialis posterior is the deepest muscle of the posterior flexor group and arises from the posterior surface of the interosseous membrane, the upper two-thirds of the posterior surface of tibia and the posterior surface of the fibula 2. The flexor digitorum longus, on the other hand, arises from the posterior surface of the tibia and the interosseous membrane
