Costochondritis
Basics
- Anterior chest wall pain and tenderness, mostly involving 2nd to 5th costal cartilages.
- Also called costosternal syndrome, parasternal chondrodynia, anterior chest wall syndrome.
- System affected: musculoskeletal.
- Tietze syndrome: inflammatory condition with swelling/redness of costal cartilage, often unilateral on ribs 2 or 3.
Epidemiology
- Predominantly affects females aged 40-50.
- Accounts for ~30% of ER visits for chest pain, 13% primary care chest pain visits.
Etiology and Pathophysiology
- Likely inflammation due to muscle pulling at costochondral/costosternal junctions.
- Causes include unusual physical activity, overuse, trauma, and recent upper respiratory infection with cough.
Risk Factors
- Upper extremity overuse or unusual physical activity.
- Trauma including accidents or domestic violence.
- Recent upper respiratory infections with cough.
Diagnosis
History
- Sharp, aching, or pressure-like chest pain, usually unilateral involving multiple costal cartilages (2nd to 5th).
- Pain worsened by upper body movement and exertion.
- Chest tightness may accompany pain.
- Complete history including cardiac risk stratification mandatory.
- Screen for domestic violence and substance abuse.
Physical Exam
- Cardiopulmonary exam to exclude cardiac/pulmonary causes.
- Tenderness over costochondral junctions confirms diagnosis.
- Pain reproducible by palpation.
- Upper extremity movement on affected side may provoke pain.
- In swelling/redness, consider Tietze syndrome.
Pediatric and Geriatric Considerations
- Pediatric: consider psychogenic chest pain or slipping rib syndrome.
- Geriatric: consider herpes zoster.
Differential Diagnosis
- Cardiac: CAD, ACS, cardiac contusion, aortic aneurysm, pericarditis, myocarditis.
- GI: GERD, esophagitis, esophageal spasm, cholecystitis.
- Musculoskeletal: fibromyalgia, slipping rib syndrome, costovertebral arthritis, painful xiphoid syndrome, rib trauma.
- Psychogenic: panic attacks.
- Respiratory: PE, pneumonia, chronic cough, pneumothorax.
- Other: domestic violence, herpes zoster, spinal tumor, metastatic cancer, cocaine abuse.
Diagnostic Tests
- Primarily clinical diagnosis.
- Imaging not routinely indicated for costochondritis.
- Consider ECG (>35 years or cardiac risk), chest X-ray (cardiopulmonary symptoms).
- CT if suspicion for aortic dissection, neoplastic or infectious causes.
- D-dimer and spiral CT if PE suspected.
Treatment
General Measures
- Reassure benign nature and slow recovery.
- Rest, local heat or ice, massage.
- Stretching exercises.
- Avoid symptom-provoking activities.
Medication
- NSAIDs (oral/topical), acetaminophen.
- Lidocaine patches, capsaicin cream.
- Skeletal muscle relaxants if muscle spasm present.
- Local lidocaine/corticosteroid injections for refractory cases (rare).
Referral
- Physical therapy for prolonged symptoms.
- Gastroenterology or cardiology if alternate diagnosis suspected.
Complementary and Alternative Medicine
- Limited evidence; may try chiropractic manipulation, exercise, dry needling, acupuncture, massage.
Admission and Nursing
- Admission only if cardiac or other serious chest pain etiology suspected.
Ongoing Care
- Follow up within 1 week if unclear diagnosis or no symptom improvement.
Patient Education
- Educate on self-limited and potentially recurrent nature.
- Avoid sudden or excessive physical activity changes.
Prognosis
- Usually self-limited; symptoms last weeks to months.
- Often recurrent or refractory in some cases.
Complications
- Refractory or recurrent chest pain.
ICD10: - M94.0 Chondrocostal junction syndrome [Tietze]
Clinical Pearls: - Costochondritis accounts for up to 30% of chest pain presentations. - Diagnosis is clinical; exclude other causes with risk-based testing. - Activity modification helps prevent recurrences.
