Costochondritis / Sternocostal Dysfunction post-MVA

Understanding Costochondritis / Sternocostal Dysfunction post-MVA

Also known as: Chest Wall Pain, Costosternal Syndrome, Anterior Rib Joint Pain, Seatbelt Chest Pain Costochondritis is inflammation of the costochondral junctions — where your ribs meet the cartilage connecting them to the breastbone (sternum). After an MVA, anterior chest wall injury is common because the seatbelt and airbag concentrate force directly over these joints. The hallmark — and the thing that distinguishes this from cardiac pain — is that the pain is reproducible by pressing along the rib-sternum junctions. Because the pain is in the chest, many patients go to the emergency department first.

That's the right call. Once cardiac causes are cleared, costochondritis becomes the working diagnosis. Sharp, stabbing, or aching pain at the front of the chest worsening with deep breathing, coughing, laughing, or rolling in bed is typical. The seatbelt compresses the anterior chest while the airbag deploys with explosive force, spraining the delicate cartilaginous joints and tearing intercostal and pectoral muscle fibers.

Inflammation typically peaks two to five days after impact. After cardiac and pulmonary clearance (we require ER or PCP clearance when indicated), treatment is gentle and effective: low-force mobilization of the sternocostal and costochondral joints, soft-tissue therapy, diaphragmatic breathing retraining, Class IV laser, and thoracic spine manipulation. Costochondritis from an MVA typically resolves over four to twelve weeks. We may recommend: Activator, myofascial release, trigger point therapy, Class IV laser, low-level laser, PEMF, corrective exercise Seek immediate care if: You have crushing chest pressure, pain radiating to the jaw or left arm, shortness of breath at rest, rapid heartbeat, coughing blood, or fainting — emergency evaluation is required before musculoskeletal care.
