Severe pain at the site of injury and breathing problems are the common symptoms experienced by individuals suffering from flail chest. In addition to these, the following are the signs and symptoms of flail chest:

[…] which is a serious consequence of flail chest and can be caused by a number of factors including ventilation/ perfusion mismatch secondary to contusion, hematoma or alveolar collapse, and inadequate tissue oxygen delivery. Flushed skin, full pulse, tachypnea [explainmedicine.com]
CLINICAL DATA OBTAINED AT THE PATIENT’S BEDSIDE The Physical Examination Vital Signs Increased Respiratory Rate (Tachypnea) Several pathophysiologic mechanisms operating simultaneously may lead to an increased ventilatory rate. [clinicalgate.com]
The patient presented with an oxygen saturation of 80% with severe dyspnea and tachypnea (32 bpm). [file.scirp.org]
- Chest Pain
A 65-year-old male pedestrian was admitted with severe chest pain and dyspnoea, after being struck by a car. The initial chest radiograph demonstrated multiple right-sided rib fractures and pulmonary contusion. [ncbi.nlm.nih.gov]
Two of the symptoms of flail chest are chest pain and shortness of breath.It occurs when multiple adjacent ribs are broken in multiple places, separating a segment, so a part of the chest wall moves independently. [en.wikipedia.org]
He is alert and responsive, but is having difficulty breathing and extreme chest pain. The emergency response providers rushed him to the hospital to be further evaluated. [study.com]
A patient with flail chest may experience chest pain and difficulty breathing or shortness of breath. This is due to paradoxical breathing. [kitaylaw.com]
It was suggested in court that this was an uncommon occurrence. [ncbi.nlm.nih.gov]
- Loss of Initiative
Among the 91 rib plates, 15 splints and 605 screws in this study there was no hardware failure and no loss of initial fixation. There was one incidence of wound infection. Implants were removed in one patient after fractures had healed. [ncbi.nlm.nih.gov]
A chest x-ray is done to analyze the condition of flail chest. The x-ray would also give information about fractures in the neighboring regions. However, x-rays are not competent enough to diagnose all rib fractures. Some of the fractures may not be spotted properly. But, when conditions such as pneumothorax, pulmonary contusion or hemothorax are diagnosed through x-ray examination it indicates that rib fractures are bound to be present.
In addition to x-ray, CT scan is also necessary to be carried out. A thoracic multi-slice computed tomography scan can identify rib fractures quite well compared to plain radiograph . However, such an examination gives little information regarding chest injuries and its use in diagnosing flail chest is limited.
Arterial blood gas measurement is also done to analyze the severity of the condition and also assess the need for mechanical ventilation. Such a kind of test helps in providing useful information during the management phase.
Pulmonary Function Test
Management of the condition and putting the patient on 100% oxygen forms the basis of treatment of flail chest. Methods to protect lungs from further damage due to injury should also be employed. It is also necessary to prevent pneumonia which is one of the grave complications of this condition. The following are the several methods employed to treat flail chest.
- Mechanical ventilation helps decrease the mortality rates and is employed for chest cavity stabilization. However, if such a method is used for longer duration then pneumonia may set in. It is also the method of choice in conditions when the chest cavity is unstable. In some cases, continuous positive airway pressure (CPAP) by mask may lower the rate of mortality in patients and lower incidence of nosocomial pneumonia . Patient in pneumatic stabilizers like CPAP has shortened duration in mechanical ventilation and have significantly lowered morbidity rates .
- Surgery: Candidates for surgery are the ones who require support from mechanical ventilation even after the wounds begin to heal. Surgical stabilization procedures have been found to shorten mechanical ventilator dependence rate . Thoracoscopy assisted minimally invasive surgery for flail chest stabilization has proven to be very promising in terms of minimal blood loss, lesser trauma and shortened hospital stay .
- Pain medications are administered to relieve the severe pain at the site of injury. Higher doses of such medications have been found to produce side effects. However, lower doses are helpful. Studies have shown that a good pain medication coverage and adequate pulmonary toilet produces better outcome in patient compared to those in mechanical ventilation .
Prognosis of the condition largely depends on the extent of injury to the rib cage, age of patient, and volume of blood loss . After discharge from the hospital, the patient is generally called for a 12 week outpatient program. In such a program, the patient is taught physiotherapy to improve mobility. After few weeks, the patient will be made to practice walking and posture correction exercises will also be taught.
If the condition of the patient is not stabilized on time, then it can give rise to various life threatening conditions. Problem in breathing followed by severe chest pain and respiratory failure are some of the major complications faced by affected individuals . The sharp edges of the broken ribs can even puncture the pleural sac as well as the lungs leading to pneumothorax. In serious conditions, if prompt treatment is not initiated it can even cause death.
Serious accidents and trauma continue to be the major causative factors. It has been estimated that about 76% of vehicle accidents contribute to flail chest. The elderly population is severely affected due to their weak bones which are frequently prone to fractures.
Children can even fall prey to flail chest either due to trauma or metabolic bone diseases such as osteogenesis imperfecta. Flail chest continues to be a leading cause of mortality and morbidity among trauma patients in both young and old .
It has been estimated that about 1 in every 13 patients who are admitted to hospital for trauma related cases suffer flail chest. Between the periods 1998 – 2003 as high as 262 cases of flail chest has been recorded. The actual numbers can be much higher that what is reported. The diagnosis of flail chest in neonates is suggestive of child abuse in most cases .
For the process of breathing to take place under normal conditions, it is required that muscle surrounding the rib cage and diaphragm move in order to expand the chest cavity. Such an activity creates vacuum which gets filled when air is inhaled. In conditions of flail chest these sequence of events do not occur as a result of which air is not drawn inside the lungs causing difficulty in breathing.
Flail chest is a condition wherein sections of broken rib cage interfere with normal movements of the chest. Therefore, it is important to immediately stabilize the condition of patients who have suffered blunt trauma. Blunt trauma not only causes flail chest but also is responsible for serious damage to the lungs.
Flail chest cannot be prevented; however, early initiation of treatment and proper management can prevent development of complications.
Flail chest is a serious condition wherein a segment of the rib cage separates from the chest wall as a result of severe injury. Due to this, the affected area is not able to contribute to lung expansion. Such a condition can be life threatening and can pose serious health risks for the individual. If prompt treatment is not initiated it can cause lifelong disability.
Flail chest is a condition caused due to blunt trauma wherein a segment of the rib cage gets separated from the chest wall. It is a life threatening condition that can lead to complications if treatment is not initiated on time.
Vehicle accidents and trauma are the major cause of chest injuries that can lead to flail chest.
An x- ray of the chest is helpful in diagnosing the condition of flail chest. In addition to x-rays, a test known as arterial gas measurement is done which is helpful in analyzing the need for mechanical ventilation. Such a test is also helpful during the management of the disease condition.
The patient is put on mechanical ventilator for stabilization of the chest cavity. Surgical procedures may be required depending upon the condition of the patients. It is often a treatment of choice when patients continue to depend on mechanical ventilator even when the wounds begin to heal. Medications to relieve pain are administered to reduce the discomfort caused due to injuries.
