Definition/Description[edit | edit source]
- It is a clinical diagnosis and does not require specific diagnostic testing in the absence of concomitant cardiopulmonary symptoms or risk factors.
- Costochondritis is often confused with Tietze syndrome.
- Palpation of the affected chondrosternal joints of the chest wall elicits tenderness  and pain is reproduced by palpation of the affected cartilage segments which may radiate out into the chest wall.
Clinically Relevant Anatomy[edit | edit source]
The thoracic wall consists of the
- Sternum anteriorly,
- 12 thoracic vertebrae posteriorly,
According to their attachment to the sternum, the ribs are classified into 3 groups: true, false, and floating ribs.
- True ribs are the ribs that directly articulate with the sternum with their costal cartilages - ribs 1-7. They articulate with the sternum by the sternocostal joints. The first rib is an exception to that rule; it is a synarthrosis and the first rib could uniquely articulate with the clavicle by the costoclavicular joint
- The false ribs (8,9,10) are the ribs that indirectly articulate with the sternum, as their costal cartilages connect with the seventh costal cartilage by the costochondral joint.
- The floating ribs (11,12) do not articulate with the sternum at all (distal two ribs).
The ribs move with respiration and with truncal motion or movement of the upper extremities.
Aetiology[edit | edit source]
Costochondritis is inflammatory. It is caused by inflammation of the costal cartilages and their sternal articulations, also known as the costochondral junctions.
Epidemiology[edit | edit source]
The epidemiology of costochondritis is not well established.
- In a small study published in 1994, there was a higher frequency of costochondritis seen in females and Hispanics.
- In a group of 122 patients presenting to the emergency department with chest pain not due to malignancy, fever, or trauma, costochondritis was the diagnosis in 36 of the patients (30%)
- Can affect children as well as adults. A study of chest pain in an outpatient adolescent clinic found that 31 percent of adolescents had musculoskeletal causes, with costochondritis accounting for 14 percent of adolescent patients with chest pain.
Characteristics/Clinical Presentation[edit | edit source]
As with any chest pain, history of present illness, past medical history, social history, family history, and a review of systems are very important. Many deadly causes of chest pain should be ruled out prior to establishing a diagnosis of costochondritis.
Possible findings include
- Patient will give a history of the pain worsening with movement and certain positions. The pain will also typically be worse when the patient takes a deep breath.
- Pain quality is variable, but it may be described as a sharp or dull pain.
- Patients report a gradual or rapid onset of pain and swelling of the upper costal cartilage of the costochondral junction.
- Pain is usually reproducible by mild-to-moderate palpation. Often, there is point tenderness where one or two ribs meet the sternum (a pitfall of the typical physical exam findings is that pain due to acute coronary syndrome can also be described as reproducible).
- Symptoms may occur gradually and can disappear spontaneously after a few days, but equally it may take years to disappear.   Even after the symptoms have resolved, they may return at the same location or at another rib level. 
- There may be hypomobility of the upper thoracic spine, costovertebral joints, and the lateral ribs.
Evaluation[edit | edit source]
Costochondritis is usually self-limited and benign - should be distinguished from other, more serious causes of chest pain.
- Coronary artery disease is present in 3 to 6 percent of adult patients with chest pain and chest wall tenderness to palpation.
- History and physical examination of the chest that document reproducible pain by palpation over the costal cartilages are usually all that is needed to make the diagnosis in children, adolescents, and young adults.
- Patients older than 35 years, those with a history or risk of coronary artery disease, and any patient with cardiopulmonary symptoms should have an electrocardiograph and possibly a chest radiograph.
- Consider further testing to rule out cardiac causes if clinically indicated by age or cardiac risk status
Differential Diagnosis[edit | edit source]
The differential diagnosis for costochondritis is rather long. Some of the diagnoses included are associated with major morbidity and mortality. eg
- Acute Coronary Syndrome (ACS)
- Pulmonary Embolism
- Tietze’s syndrome, much less common than costochondritis, and it tends to cause chest swelling in addition to the other symptoms,
- Xiphoidalgia: painful swelling and discomfort of the xiphoid process of the sternum 
- Slipping Rib Syndrome: hypermobility of the anterior ends of the false rib costal cartilages 
Outcome Measures[edit | edit source]
Patient-specific functional scale ( PSFS): specific questionnaires for costochondritis have not yet been produced, but the PSFS is a valid, reproducable, and responsive outcome measure for patients with neck pain, back pain, and upper quarter complaints 19
Measurement of thoracic and cervical mobility:
- Rotation of the thoracolumbar spine (TR): TR has high validity and sensitivity ranks and improvement of the measurement technology would probably result in a superior test for the follow-up.
- Finger to floor distance (FFD): high reliability and sensitivity, but poor correlation with spinal changes
- The Schober test
- Thoracolumbar flexion
- Occiput to wall distance 
Examination[edit | edit source]
Patients with Costochondritis will present with:
- Chest pain reproducible by palpation of the affected area, with ribs 2 to 5 mostly affected.
- Aggravating factors can be slouching or exercise.
- Often occurs after a recent illness with coughing or after intense exercise and it mostly of unilateral origin.
- May be an associated restriction of the corresponding costovertebral and costotransverse on examination.
- Loss of normal spinal movement associated with the chest pain.
- Palpation should be performed with 1 digit, on the anterior, posterior, and lateral side of the chest, the clavicle, the cervical and thoracic spine. When on the affected area it reveals a reproducible pain which might suggest Costochondritis, but it cannot entirely concluded.
- Motion palpation is a manual process of moving a joint into its maximal end range of motion, after which it is challenged with a light springing movement. This end point of joint movement forms the basis for determining the normal or abnormal joint movement. When motion palpation is reduced, the joint is considered fixated or hypokinetic.
- Cardiac causes should be ruled out in patients who present with a high risk.
Medical Management[edit | edit source]
Treatment consists of conservative management and is usually symptomatic, 
- Topical or oral analgesics.
- Local injections with steroid into the joint, tendon sheath or around the nerve, inhibits inflammation, reduces swelling and pain to improve movement. 
- If patients have severe or refractory costochondritis, refer for outpatient follow-up. Physical therapy is a treatment option for refractory costochondritis
- Alternative treatments may also include: ice, acupuncture, manual therapy, exercise, and other medications such as sulfasalazine which may have an additional long-term benefit in the management of costochondritis 
Physical Therapy Management[edit | edit source]
- Education - reassure the patient by explaining the condition 
- Minimising activities that provoke the symptoms (e.g. reducing the frequency or intensity of exercise or work activities)
- A course of trigger point therapy to reduce pain - eg.cross fibre friction massage
- Use heat/ cold pads and massage to help against the overloading of muscles and to lessen the pain. Heat and cold pads are both equally effective. So the patient can choose which one he likes the most. Instead of using cold pads, the patient can also use Vapocoolant spray on the involved areas. This spray can relief the pain on the chest.
- Postural exercises - Re-train proper posture in functional positions (Neuro-muscular control). Functional training is all about using the right muscles at the right time, to sustain the correct posture, in daily activities. Simple activities like eg. correct standing posture, sit to stand and walking up stairs all need be addressed to ensure correct technique and muscle recruitment.
- Thoracic manual therapies directed at the lateral and posterior rib structures to improve rib and thoracic spine mobility
- Exercises in the range of motion should be induced as soon as possible. The patient may not have pain when he is doing the exercises eg.rotation exercises for thoracic spine. Do not invoke pain.
- Progressive stretches. They can begin with simple mobility exercises as tolerated eg  Stretching of the M. pectoralis major can be helpful (stretch the M. pectoralis major, stand in a corner for 10 sec with both of your hands against the wall (like when you do a push-up)repeat it a few times a day for 1 or 2 minutes).
- Mobilisation of the spine and ribs to improve thorax mobility and to reduce symptoms. 
- On the painful area they can use transcutaneous electrical stimulation and electroacupuncture. The acupuncture needle is placed within the involved spinal segment. Than low-frequency electrical currents are applied on the inserted needle.
- Dry needling : Musculoskeletal chest wall pain has traditionally been a difficult area to evaluate and treat. Dry needling in the hands of properly trained providers may aid in diagnosis and treatment of focal chest wall syndromes

Clinical Bottom Line [edit | edit source]
Costochondritis should be a diagnosis of exclusion. Rule out other causes of chest pain that are associated with increased morbidity and mortality.
- Patients typically present with chest pain worse with breathing, and it is often positional.
- Costochondritis is a self-limited disease.
- It should be reproducible on a physical exam, and the patient's vital signs should be within normal limits. If ordered, labs, ECG, and chest x-ray should also be normal.
- Diagnosis is confirmed by a scan or bone scintigraphy and by a physical assessment of the affected costal cartilage.
- The treatment of costochondritis consists of conservative management and is usually symptomatic .
- Physiotherapy is often ordered if the condition does not respond to treatment (see physiotherapy section for details).
