Diagnostic imaging of spine trauma
To choose the treatment tactics, the physician needs a precise understanding of the nature of the injuries. In modern traumatology, two high-tech methods play a key role:
- Computed tomography (CT). Allows for a three-dimensional (3D) reconstruction of the vertebrae, which is critically important for spatially understanding the arrangement of fragments in burst and comminuted fractures. CT excellently detects free bone fragments in the spinal canal and enables quantitative analysis of bone mineral density (screening for osteoporosis). However, the presence of metal implants creates artifacts that drastically reduce image quality.
- Magnetic resonance imaging (MRI). Based on the phenomenon of nuclear magnetic resonance. This is the most informative method for visualizing soft tissues. MRI details the state of the spinal cord, intervertebral discs, and spinal nerve roots. The method can detect hidden contusions and trabecular bone microfractures that are completely invisible on radiographs and CT scans.
Conservative treatment and orthotic management
There is no single universal method for treating fractures. Conservative approaches require the specialist to have a deep understanding of biomechanics and high qualifications. The main conservative methods include plaster casts, continuous traction, and positioning therapy.
Positioning therapy is essentially immobilization without the use of external or internal fixators. For example, stable compression fractures of the lumbar spine are treated by placing the patient on a repositioning bolster under strict bed rest conditions. Important: this approach is often mistakenly called "functional," although the true functional method involves preserving the function of the injured segment.
For external spinal fixation, orthoses are actively used:
- Orthopedic braces: available as stabilizing (rigid, semi-rigid, soft) and corrective (used for deformities such as scoliosis and kyphoscoliosis).
- Bandages: elastic support products.
Main rule: prolonged use of braces inevitably leads to muscle atrophy. The patient must be prescribed regular physical therapy (exercise therapy) sessions to compensate for this negative effect.
Rehabilitation and a systemic approach
Rehabilitation is an independent branch of medicine. Treatment of spinal injuries is based on the principle of anthropotherapy, proposed by classics of Russian medicine (M. Ya. Mudrov, G. A. Zakharyin, S. P. Botkin). The core idea: the physician must treat not a localized bone fracture, but the sick person as a whole.
Prolonged bed rest (hypodynamia) triggers a cascade of systemic disorders:
- The intensity of kinesthetic stimuli decreases and their pattern becomes distorted.
- The dynamic stereotype of physiological functions is disrupted.
- A breakdown occurs in the basic system of motor-visceral reflexes.
In addition, severe trauma, pain, and the fear of consequences severely depress the patient's psyche. To combat these phenomena, exercise therapy is used. Its main goals are to neutralize the harm of hypodynamia, accelerate reparative processes, and restore lost motor functions.
Historical background
Domestic operative vertebrology has come a long way in its formation. Its founder is rightfully considered to be V. D. Chaklin. Subsequently, the field was actively developed by such prominent specialists as A. I. Kazmin, Ya. L. Tsivyan, A. I. Osna, I. M. Mitbreit, A. I. Protsenko, S. T. Vetrile, Kh. A. Musalatov, L. L. Silin, and G. S. Yumashev. It was under the leadership of G. S. Yumashev that a comprehensive system of treatment and subsequent rehabilitation for patients with severe injuries and diseases of the spinal column was established.
To avoid confusing diagnostic imaging methods, use a simple rule: "CT is for bones and fragments (3D reconstruction); MRI is for the spinal cord, discs, and hidden injuries."
Class and exam questions
What is the difference between positioning therapy and the functional method?
Positioning therapy is strict postural fixation without external devices (e.g., prolonged lying on a bolster). The functional method, by contrast, involves partial or complete preservation of movement in the injured segment; therefore, these terms must not be confused.
Which tomograph is better to use in spine trauma?
The choice depends on the clinical objective. CT better shows the spatial arrangement of bone fragments in burst fractures. MRI is indispensable for assessing the state of the spinal cord, spinal nerve roots, and detecting hidden microfractures.
Why shouldn't an orthopedic brace be worn constantly?
Prolonged external spinal fixation takes over the work of the muscles, which inevitably leads to their rapid atrophy. Wearing a brace must always be accompanied by regular physical therapy sessions.
