Xray Images of Fracture of D12 With Dislocation D11 Vertebra Over D12

Follwing xrays are of thoracolumbar spine of patient with spinal injury. The patient has fracture of D12 vertebra and dislocation of D11 over D12 vertebra.

Complications Of Spinal Injuries In Thoracic & Lumbar Spine

Injuries to thoracolumbar spine can lead to a variety of potential complications.

Nonsurgical Complications

These complications are not related to surgical procedures and in most cases are related to injury pattern.

Neurological Deficits

Neural deficit is quite a significant problem associated with thoracolumbar injuries. While early neural deficits are following injury to the cord, delayed deficits can be due to  syrinx formation after thoracolumbar trauma. [Read more...]

Flexion Distraction Injuries of Thoraco Lumbar Spine

Flexion-distraction, or seat-belt fractures may be either one- or two-level injuries. The classic one-level injury is the Chance Fracture.

The classic mechanism involves the patient being thrown forward across an intact lap-belt, resulting in a hyperflexion force acting around a center of rotation anterior to the spinal column at the belt.

This results in distraction forces at all three columns of the spine

  • The posterior elements are torn apart through either the facet joints or the bone itself
  • The middle column is torn apart through either the posterior disc or the posterior vertebral body
  • The anterior column is either disrupted in severe injuries or left as a hinge that cannot resist either flexion or rotational displacement

There could be associated injuries frequently due to violent compression of viscera between the spinal column and lap belt. Rates of intra-abdominal hollow viscus injury is reported as high as  50%. [Read more...]

Operative Treatment Of Thoracolumbar Burst Fractures

Surgical treatment of the burst fractures involves decompression and stabilization. The spine can be approached through anterior and posterior approach. Both the routes have their own advantages and disadvantages.

Indications For Surgery In Thoracolumbar Burst Fractures

  • A progressive neurologic deficit
  • Presence of a posterior ligament complex injury
  • Neurologic deficit with or without an unstable fracture
  • Rapidly increasing kyphotic deformity.
  • Fractures in multiply injured patients
  • Those who are candidates for conservative treatment but refuse it or conservative treatment cannot be employed because of body habitus.

Posterior Surgery

Advantages

  • Avoids the morbidity of anterior exposure in patients who potentially have concomitant pulmonary or abdominal injuries.
  • Shorter operative times
  • Decreased blood loss
  • Functional outcomes are similar to those following anterior surgery

Disadvantages

Through posterior approach posterior instrumentation is done [Instrument used to fix the spine is posterior]. Posterior instrumentation alone cannot reconstitute anterior column support. Therefore the construct is somewhat weaker than anterior instrumentation when subjected to compressive forces. [Read more...]

Compression Fractures In Thraco Lumbar Spine

Compression fractures are the result of failure of the anterior column by forward flexion forces. Most of these fractures are associated with minor trauma and osteporosis.

They rarely are associated with neurological deficit except when multiple adjacent vertebral levels are affected.

Non Operative Treatment

Most of these fractures can be managed by non operative means. [Read more...]

Fracture L3 Vertebra – Lateral Radiograph

29 years lady was sitting in auto rickshaw which was struck by a car from behind. THe woman was thrown out of the auto rickshaw and the auto rickshaw fell on the lady.

She was brought to casualty of our hospital and found have injured her pelvis and spine along with paraplegia.

The xray in picture is lateral view of the spine and shows fracture of L3 vertebra.

MRI of the spine revealed a retropulsed fragment as well. She was operated upon and the spine was stabilized using pedicle screw system.

Fracture of C1 Vertebra or Atlas

Atlas fractures can be  stable or unstable injuries.  This fracture has very high association with  injuries to other areas of the spine.

A fracture of atlas vertebra should cause enough alert to search for injuries in other region of the spine.

Almost 43%  of all C-1 fractures are found to be associated with a C-2 fracture.

Atlas fractures have been divided into following 5 types. [Read more...]

Spinal Injury – An Overview of Definitive Treatment

After initial care of the patient with spinal injury, decision is made about the definitive care. A definitive care  aims at making the injured spine stable and removing any decompression on the spinal cord.

Because not all patients would have neural injury and not all patients would have instability of the spine, the definitive treatment has a spectrum from immobilization with a collar to surgery. There are indications for each method and one treatment cannot treat all kind of injuries.

Following are the ways of treating a spinal injury

  • Non operative  Treatment
  • Operative treatment
  • Closed reduction with or without surgery (in cervical spine only)

[Read more...]

What Is Spine Clearance

The rate for missed or delayed diagnosis of cervical spine injury is 1-4%. The most frequent reasons for missed injuries are inadequate assessment, inadequate radiographs and misinterpretation of radiographs. Patients who deteriorate from a missed injury may have severe complication like death, quadriplegia other new neurologic deficits.

Therefore, a potential spinal injury should be assumed and the patient protected should be protected unless declared free of spinal injury or definitive treatment is provided. it has been found that neurologic deterioration after admission occurs in 5% of spine injury patients and most of it can be prevented if precautions are observed.

Spine clearance is a combination of clinical patient assessment and radiographic evaluation . [Read more...]

Spinal Injuries – Detailed Examination After Patient Resuscitation

After initial examination , complete spine examination and neurological assessment follows resuscitation. This detailed assessment begins with review of reports from the field.

This detail examination follows a different sequence in unresponsive and awake (cooperative) patients and and awake sequence of evaluation and intervention steps differs in unresponsive patients from awake and cooperative patients.

History

If patient is responsive, a detailed history is obtained regarding acute symptoms and past history.

For unresponsive patients, a past history is obtained from family members or available previous medical records. [Read more...]
