Deep Posterior Compartment

See also:

• Laeral Compartment
• Anterior Compartment
• Superfical Posterior Compartment

Discussion

• contains tibialis posterior, FDL, & FHL;
• originates primarily from posterior tibia, fibula, & interosseous membrane in proximal 2/3 of leg, these structures are involved in plantar flexion of foot & toes & inversion of foot thru tibialis posterior msucle function;
• major neurologic structure is posterior tibial nerve;
• 2 major arteries, peroneal artery & posterior tibial arteries, are present in this compartment;
  • posterior tibial art, because of its protected nature, frequently is major arterial supply after significant open frx & is a potential source for anastomosis
    • w/  free flaps for soft tissue recontruction of the leg;

Compartment Syndrome

• clawing of the toes, a common sequela of posttraumatic compartment syndrome within the deep posterior compartment following a distal third tibia fracture;
• this may be due to the potential communication between the deep posterior compartment and the compartments of the foot

• The deep posterior compartmental syndrome of the leg.
• Anatomic investigation of the deep posterior compartment of the leg.
• Anatomical variations within the deep posterior compartment of the leg and important clinical consequences.
• Anatomical dissection of the deep posterior compartment and its correlation with clinical reports of chronic compartment syndrome involving the deep posterior compartment.
