Stroke is a major health problem in India. 80% strokes are ischemic strokes and remaining 20% are hemorrhagic. In hypertensive patient, cause of ischemic stroke is mostly due to atheroma formation in the arteries. Uncontrolled high blood pressure increases a person's stroke risk by four to six times.

The risk of stroke is directly related to how high the blood pressure is. Stroke patients may have an increased risk of fractures because of weak bones or an increased risk of falling. Females, older age, low abbreviated mental test score and pre-stroke dependence are associated with an increased fracture rate. In animal model bone fracture increases alarmins and proinflammatory cytokines in the blood, and provokes macrophage infiltration and proinflammatory cytokine expression in the hippocampus.

In murine experiment Bone fracture, shortly after stroke, enhances stroke-related injuries in brain by augmenting the neuro-inflammatory response. Many studies state cause of fractures after stroke but it is uncommon for ischemic stroke to occur after traumatic fracture.

We present an uncommon occurrence of ischemic stroke on third day post traumatic fracture supracondylar femur in a 45-year-old known hypertensive patient.

Case Study

A 45-year-old male presented to our institute with history of fall from bicycle previous day causing injury to right thigh. Diagnosis of fracture shaft of right side femur distal 1/3rd was made. Patients was known case of hypertension on Tab. Amlodipine 5 mg od and his vitals were found to be stable with B.P- 130/88 Pulse – 88 per min. RR-18/min afebrile and routine blood investigations found to be normal. Upper tibial skeletal traction was applied.

On third day patient developed sudden weakness of the right side of the body with complete hemiplegia of right side of the body along with motor aphasia. Patient blood pressure found to be 138/90 at that time. Neurology consultation was taken and patient was investigated accordingly.

Ncct- Head on same day showed feature s/o acute middle cerebral artery infract left side.

Cxr Pa- Normal

Ecg- Left ventricle strain pattern

Echo- Concentric left ventricle hypertrophy, normal ejection fraction of 60%. No thrombus with gd 4 diastolic dysfunction

Color Doppler Carotid- 33% blockage of left middle cerebral artery.

Patient was put on Tab. Ecosporin 150 mg OD and Rosuvastatin 10 mg HS. There was gradual recovery in power to 1/5 as per MRC grading in wrist, elbow, toes and ankle joints within first week of starting drugs.

Same drugs were continued and there was further recovery to 3/5 at wrist, elbow and shoulder in upper limb. Speech recovered but power in lower limb cannot be accurately graded due to injury, roughly it was 2/5 at ankle.

MRI showed left middle cerebral artery infarct with involvement of the lacunar branches.

One month later Patient was operated with Distal Femur Locking Plate using Swashbuckler approach under combined spinal epidural anaesthesia. No further recovery was noted in post op period and patient was discharged subsequently and is being kept in OPD (Outpatient Department treatment) follow up (Figures 1 and 2).

Stroke is classified into ischemic and hemorrhagic [1-7]. There are various risk factors of stroke classified as modifiable and non-modifiable. The non-modifiable age, gender, race, ethnicity, and heredity have been identified as markers of risk for stroke. Although these factors cannot be modified, their presence helps identify those at greatest risk, enabling vigorous treatment of those risk factors that can be modified [8]. Age is the single most important risk factor for stroke. For each successive 10 yrs after age 55, the stroke rate more than doubles in both men and women [9-11]. Age of our male patient was 45 yrs only.

There are modifiable risk factors for stroke which are as follows. Hypertension is the single most important modifiable risk factor for ischemic and haemorrhagic stroke [12]. Other modifiable risk factors include Cardiac Disease Diabetes, Hyperlipidaemia, Cigarette Smoking, Alcohol, Illicit Drug Use etc. [8]. Our patient was known hypertensive on treatment with controlled hypertension.

Various lifestyle modifiable factors have been associated with increased stroke risk. These include obesity, physical inactivity, diet, and acute triggers such as emotional stress [13,14].

Bone fracture is an injury which causes inflammation in the initial phase which peaks at 24 h and last for a week [15]. This leads to release of cytokines, bone morphogenic proteins, mesenchymal stem cells in a controlled manner [16]. Polymorhonuclear leucocytes constitute 50-60% of the leucocytes and releases IL 1, IL 6 and TNF alpha [17]. Fibrinogen is an acute phase reactant released by liver in response to injury [18]. Fibrinogen has been linked to increase incidence of carotid artery stenosis and risk of recurrent stroke [19]. It has effect on the viscosity, platelets, atherogenesis and act as a substrate for thrombin leading to clot formation [19] in early post injury period, IL-6 levels correlates with complications and mortality [20] complications attributed after trauma due to IL 6 are increase chances of infection and ARDS [21-23]. IL 6 has been associated with up regulation of levels of fibrinogen in response to trauma in animal model [20]. We assume that this link might also be true in human model leading to episode of stroke in our patient as fibrinogen increases the risk of stroke. None of the clinical studies have reported a case of stroke after acute traumatic event.

During stroke loss of consciousness may lead to fall which can cause bony injuries, especially in elderly and may cause fractures, but post fracture ischemic stroke is not described well in literature. It has been proved in animal models that bone fracture increases alarmins and proinflammatory cytokines in the blood, and provokes macrophage infiltration and proinflammatory cytokine expression in the hippocampus which may lead to post injury ischemic stroke as in our case.


Post injury ischemic stroke is an unheard identity. Animal research shows that trauma increases the chances of clotting though human reports are lacking. Fibrinogen is one of the modifiable risk factor for stroke. IL 6, which increases in acute inflammatory phase of fracture healing, has been associated for up regulating the fibrinogen levels in animal model. It has been found in animal model that bone fracture increases alarmins and proinflammatory cytokines in the blood, and provokes macrophage infiltration and proinflammatory cytokine expression in the hippocampus. These factors might have led to ischemic stroke in our patient.

These mediators may cause further injury to brain in predisposed at risk patients as was in our case. Although rare in occurrence surgeon should be aware of this. Further studies are needed to establish this association.
