Introduction</title><p>Osteoporosis is a common disease in the elderly, currently affecting more than 10 million people in the United States [<xref rid="B1" ref-type="bibr">1</xref>]. The decrease in bone density compromises its structural integrity, resulting in an increased rate of fractures. The most common locations for these types of fractures are the spine, humerus, wrist, pelvis, and hip [<xref rid="B2" ref-type="bibr">2</xref>]. Many of these fractures are insufficiency fractures, a subgroup of stress fractures where a break is due to normal or physiologic stress upon weakened bone.</p><p>We present two cases of minimal low-energy trauma associated with thoracic spine fractures as the cause of haemothoraces in geriatric patients. While a number of haemothoraces from thoracic spinal fractures related to massive trauma have been reported [<xref rid="B3" ref-type="bibr">3</xref>–<xref rid="B5" ref-type="bibr">5</xref>], a review of the literature for fractures from low-energy traumatic events failed to reveal a single case. The purpose of this case study is to report on the potential risk of fatal haemothorax due to low-energy traumatic spinal insufficiency fractures.</p></sec><sec id="sec2"><title>2. Case Report</title><sec id="sec2.1"><title>2.1. <bold></bold>1st Patient Case</title><p>A 93-year-old white male presented to the emergency department (ED) with a chief complaint of weakness and recurrent falls combined with a history of osteoporosis, dementia, and an inability to care for himself. Upon examination, decreased breath sounds in the right lung were noted, and a chest X-ray revealed a large right pleural effusion. A computed tomography (CT) scan of the chest confirmed the suspicion of a pleural effusion and revealed multiple rib fractures at various stages of healing, a clavicular fracture, L1-L2 vertebral body compression fractures, and a large lucency at the anterior aspect of the approximate T10 vertebral body (<xref ref-type="fig" rid="fig1">Figure 1</xref>). The patient underwent a thoracentesis yielding 1000 mL of hemorrhagic fluid.</p><p>Due to the patient's poor nutritional status and the family's decision to decline further treatment, palliative care was initiated. The patient expired four days after admission. The patient had a history of asbestos exposure in the distant past, and, as a result, the family requested an autopsy to determine whether mesothelioma was the cause of the hemorrhagic pleural effusion.Autopsy showed the body of a well-developed, emaciated adult white male weighing 110 lb and 67.5 inches tall (BMI = 17.0 kg/m<sup>2</sup>). Examination of the thoracic cavity revealed recent fractures of his left 2nd and 3rd ribs as well as multiple healing fractures bilaterally. No blood was emanating from any of these fractures. Most notably, however, was a 2000 mL haemothorax (<xref ref-type="fig" rid="fig2">Figure 2</xref>) which had arisen from fractures of the 10th and 11th thoracic vertebrae with associated laceration of the posteromedial aspect of the right parietal pleural lining, overlying the fracture site (Figures <xref ref-type="fig" rid="fig3">3</xref>, <xref ref-type="fig" rid="fig4">4</xref> and <xref ref-type="fig" rid="fig5">5</xref>). Adherent blood clots were present near the laceration site as well as on the lung subjacent to the fracture site. The overlying large-caliber vasculature (aorta, vena cava, and branches) was intact and uninjured. Although fibrous pleural plaques consistent with asbestos exposure were observed, no evidence of mesothelioma was present, either grossly or by microscopic examination.</p><p>Given the autopsy findings, as well as his history of recurrent falls and underlying osteoporosis, his thoracic spine fractures were most likely sustained from a recent fall and ultimately determined to be the immediate cause of death related to a massive haemothorax. The manner of death was ruled an accident.</p></sec><sec id="sec2.2"><title>2.2. <bold></bold>2nd Patient Case</title><p>A 71-year-old white male status post sigmoid colectomy for removal of a colorectal carcinoma developed acute respiratory distress postoperatively, after being moved from the operating table, and was reintubated. Attempts to wean the patient from the ventilator resulted in continued distress and subsequent respiratory failure. The patient quickly declined and progressed to cardiopulmonary arrest. After approximately an hour of resuscitation efforts and stabilizing the patient, he was transferred to the intensive care unit (ICU), where a chest X-ray revealed a large right pleural effusion of unknown origin. A chest tube was placed and 3000 mL of hemorrhagic pleural fluid was withdrawn. A subsequent chest CT did not reveal an obvious source of hemorrhage (<xref ref-type="fig" rid="fig6">Figure 6</xref>). As time progressed and the patient remained nonresponsive after numerous interventions, it became exceedingly clear that the patient had suffered a severe irreversible anoxic encephalopathy from the prolonged cardiopulmonary arrest. The family agreed to withdraw life support secondary to the patient's irreversible medical condition.</p><p>Autopsy showed the body of a well-developed, morbidly obese adult white male weighing 330 lb and 74 inches tall (BMI = 42.4 kg/m<sup>2</sup>). Examination of the thoracic cavity revealed 1000 mL of serosanguineous fluid with clotted blood within the right chest cavity as well as 400 mL of serosanguineous fluid within the left chest cavity. This fluid originated from the posterior chest wall near the lower thoracic spinal column (<xref ref-type="fig" rid="fig7">Figure 7</xref>). Originally, an aortic injury was suspected, but the aorta was free of acute trauma, demonstrating only focal complicated atherosclerotic plaque (<xref ref-type="fig" rid="fig8">Figure 8</xref>). The hemorrhage arose from a fracture of the 11th thoracic vertebral body (Figures <xref ref-type="fig" rid="fig9">9</xref> and <xref ref-type="fig" rid="fig10">10</xref>), presumably having occurred while moving the patient from the operating table to the hospital bed for transport to the recovery room, as no other sources of trauma could be identified. Microscopic examination of the spine demonstrated an insufficiency fracture secondary to osteoporosis. No evidence of malignancy was present.</p><p>Based upon the gross and microscopic findings in the decedent's autopsy, massive haemothorax from a fractured thoracic vertebra with underlying osteoporosis was the cause of death. The manner of death was ruled an accident.</p></sec></sec><sec id="sec3"><title>3. Discussion</title><p>Over 750,000 vertebral compression fractures (VCFs) occur each year in the United States [<xref rid="B1" ref-type="bibr">1</xref>]. Of these, 20% occur in people above 70 years of age [<xref rid="B6" ref-type="bibr">16</xref>]. These VCFs account for an estimated 27% of all osteoporotic fractures [<xref rid="B6" ref-type="bibr">16</xref>–<xref rid="B8" ref-type="bibr">18</xref>]. Risk factors for osteoporosis include long-term glucocorticoid therapy, low body weight, family history of hip fracture, cigarette smoking, excessive alcohol intake, history of previous fracture, dietary calcium or vitamin D deficiency, and advancing age [<xref rid="B10" ref-type="bibr">19</xref>]. Trauma associated with VCFs occurs when the weight of the upper body exceeds the bones' capacity to support the load within the vertebral body. The force causes the anterior portion of the vertebral body to crush, forming a wedge fracture. This leads to a kyphotic deformity as the spine bends forward from the resultant loss in the anterior height [<xref rid="B11" ref-type="bibr">20</xref>]. Hemorrhage in VCFs occurs mainly from the azygos and hemiazygos vein, intercostal artery, and external vertebral venous plexus [<xref rid="B12" ref-type="bibr">9</xref>]. A paravertebral hematoma forms due to bleeding from those vessels. If the parietal pleura is undamaged, spontaneous hemostasis will likely occur [<xref rid="B12" ref-type="bibr">9</xref>]. In these two patient cases, osteoporosis led to an insufficiency fracture of the thoracic spine and as a result created an unstable environment by which the patients developed haemothoraces and rapid clinical deterioration. </p><p><xref ref-type="table" rid="tab1">Table 1</xref> provides a recap of many of the extensive differential diagnoses for pleural effusion. When discussing the causes of a pleural effusion in the elderly, haemothorax from a thoracic spinal fracture is not a common cause and certainly low on a list of differential diagnoses. However, in order to treat these patients effectively, clinicians must always consider this etiology, especially in those with risk factors or predisposing conditions.</p><p>In conclusion, we hope that this paper will serve as a reminder to physicians of the potential common and uncommon causes of haemothoraces. Haemothoraces from thoracic spinal fractures can often be overlooked, especially when it appears that little to no trauma has occurred. With the increasing elderly population and the consequential increasing incidence of osteoporosis, we expect cases similar to these to become more prevalent.
