The medial compartment of the thigh is the adductor compartment, lying between the anterior and posterior compartments on the inner thigh. It contains the adductor muscles, gracilis, pectineus and obturator externus, most supplied by the obturator nerve.

Function & Actions

Holds the muscles that adduct the thigh and stabilise the pelvis.

Clinical Relevance

Clinical Notes

Groin strains most often involve adductor longus in this compartment. Compartment syndrome is rare here, but haematomas from adductor tears or anticoagulation can be large. The obturator nerve in this compartment can be blocked to prevent thigh adduction during bladder surgery.

Pathology

Common Injuries & Conditions

Adductor Strain

A tear of the adductor muscles, usually adductor longus near its origin, causing groin pain with kicking, sprinting and changing direction.

Obturator Nerve Injury

Damage to the obturator nerve in pelvic surgery or fractures, causing adductor weakness and numbness on the inner thigh.
