## Overview Strain or tearing of the costal digitations of the external abdominal oblique muscle produces localized pain and swelling over the ribs or flank. Severe disruption can lead to abdominal wall herniation. Trauma from kicks or sudden rotational effort is the usual cause. ## Causes Blunt trauma or acute overload. ## Diagnosis Palpation of pain and swelling, ultrasound of the body wall, and exclusion of rib fracture. ## Treatment Rest, anti-inflammatories, and support. Surgical repair if a hernia develops. ## Recovery and Prognosis Good for simple strains. Hernias require surgical consideration. ## Prevention Trauma avoidance.
localized swelling over the ribs or flank; pain on palpation; reluctance to bend laterally; possible hernia if severe
