Transverse Foramen Fractures

    • Treatment of Transverse Foramen Fractures

Transverse foramen fractures are the fractures which occur in or extend to transverse foramen. The transverse foramen is also known as foramen transversarium. Transverse foramen fractures are important because of their association of vertebral artery injury.

The transverse foramen is an opening on each of the transverse processes of the cervical spine which gives passage to the vertebral artery and vein and a sympathetic nerve plexus.

Cervical radiculopathy and brachial plexus palsy is found in 10% of patients with transverse foramen fractures.

Dissection or occlusion of the vertebral artery has been reported in 88%  of transverse process fractures that extend to transverse foramen.

Transverse foramen fractures in the cervical spine can cause injury to the vertebral artery. It can occur as a result of occlusion, laceration, or distractive avulsion of the artery.

The incidence of vertebral artery injury following lower cervical spine trauma has been reported to be as high as 46%.

Transverse foramen fractures have been associated with facet dislocations, facet fractures with translation, and transverse foramen fractures.

Majority of injuries are unilateral.

Diagnosis

Detection of the injury can has important influences on overall decision making.

An x-ray would raise the suspicion of transverse foramen fracture. MR arteriograms are an effective means of noninvasive diagnosis of vertebral artery occlusion or narrowing following cervical trauma.

Arteriography is another option. Vertebral angiography should be considered when patients with transverse process fractures extending into the transverse foramen develop signs and symptoms of vertebral-basilar artery insufficiency.

Bilateral vertebral artery injuries can be devastating, leading to cerebellar infarction.

Treatment of Transverse Foramen Fractures

The injury is managed on the lines of cervical injuries.

The vast majority of injuries are unilateral, which have a very low rate of clinical sequelae. In most cases, no specific treatment is necessary. Most of the injuries of vertebral artery are also asymptomatic.

Vertebral artery injuries associated with cervical spine trauma most frequently involve the second segment that runs through the transverse foramen of C6 to C1. If the collateral flow is inadequate, an occlusion may cause vertebrobasilar ischemia.

However, the presence of arterial injury does affect the treatment decision of the fracture.

Classification of Anesthetic Agents

There are many different anesthetic agents available and the user may vary depending on the site of the procedure, type of anesthesia [local versus spinal] and duration of anesthesia sought. In addition to this patient’s allergy profile needs to be taken into account. Lidocaine is the most commonly used anesthetic and belongs to the amide […]

thromboprophylaxis

Thromboprophylaxis in Orthopedic Surgeries

Thromboprophylaxis stands for prophylactic measures to decrease the risk of venous thromboembolism by measures that promote venous outflow from the legs and drugs that reduce thrombosis. Venous thromboembolism which encompasses pulmonary embolism and deep vein thrombosis is a major cause of morbidity and mortality in hospitalized patients. Thromboprophylaxis is the most effective strategy to reduce […]

Classification of Atlantoaxial Rotatory Subluxation

Atlantoaxial Rotatory Subluxation

Also called atlantoaxial rotatory fixation, atlantoaxial rotatory subluxation is a condition where there is a fixed rotation of C1 over C2. This condition occurs when normal motion between the atlas and axis becomes limited or fixed either spontaneously or following minor trauma [which usually is the case]. It can also or follow an upper respiratory […]

Exercise Associated Muscle Cramps

Exercise Associated Muscle Cramps

Exercise associated muscle cramps are skeletal muscle cramps that occur during or shortly following exercise in healthy individuals with no underlying metabolic, neurological, or endocrine pathology. It could affect single or multiple muscles. Exercise-associated muscle cramps are common in both the recreational and the competitive athlete. Causes of Exercise-associated muscle cramps The cause is unknown. […]

Bone Destruction- Patterns and Their Significance

Different patterns of bone destruction as observed on x-rays are caused by a variety of disease processes affecting the bone. Different types of destructions suggest the intensity and aggression of the disease process. Classically, x-rays were used for imaging and diagnosis. With the advent of CT and MRI, the x-ray diagnosis of lesions has lost […]

Osteochondroma and Multiple Hereditary Exostoses

Osteochondroma is a cartilage-capped bony projection on the external surface of a bone and is considered a non-neoplastic anomaly similar to hamartoma. It can occur as a  solitary lesion or as multiple hereditary exostoses associated with anomalies of skeletal modeling. Solitary osteochondroma is a developmental anomaly of bone that results in the formation of an […]
