Lateral Thigh Compartment Space

compartimentum laterale femoris

The lateral thigh compartment is defined by the lateral intermuscular septum medially, the fascia lata laterally, and contains the vastus lateralis anteriorly. The tensor fascia lata and iliotibial band contribute to the lateral compartment fascia. This is the least commonly affected compartment in thigh crush injuries.

Region: Thigh

Clinical Relevance

Clinical Notes

Lateral thigh compartment syndrome is rare but occurs in severe thigh crush injuries alongside anterior and posterior compartment involvement. Three-compartment fasciotomy is required for complete thigh decompression. The lateral femoral cutaneous nerve runs adjacent to the lateral compartment fascia and is at risk during fasciotomy. Haematoma from femoral shaft fracture most commonly accumulates in the anterior thigh compartment but may involve the lateral compartment.

Pathology

Common Injuries & Conditions

Lateral Thigh Compartment Syndrome

Pressure elevation in the lateral thigh compartment from severe crush injury producing vastus lateralis ischaemia and lateral femoral cutaneous nerve compression, requiring surgical fasciotomy as part of three-compartment thigh release.
