What Is a Spinal Cord Injury?

A spinal cord injury (SCI) occurs when trauma, disease, or other damage disrupts the spinal cord’s ability to transmit signals between the brain and the body. The spinal cord is a vital structure that acts as the main communication highway between your brain and your limbs, muscles, and organs. An injury to it can result in a wide range of physical and sensory impairments.

Depending on the level and severity of the injury, SCI can lead to either paraplegia (affecting the lower limbs) or tetraplegia (affecting all four limbs and the torso).

What Is Tetraplegia?

Tetraplegia (also known as quadriplegia) is a condition caused by injury to the cervical spinal cord—the uppermost portion of the spinal column, usually at levels C1 to C8. This type of injury results in partial or complete paralysis of both the upper limbs, lower limbs, and trunk.

The degree of impairment varies based on:

• The level of injury (which vertebra is affected)

• Whether the injury is complete or incomplete

Levels of Cervical Injury and Typical Impairments:

Causes of Tetraplegia

Tetraplegia may result from:

• Traumatic injuries: car accidents, falls, sports injuries, diving accidents

• Medical conditions: tumors, spinal stenosis, infections, or degenerative diseases

• Non-traumatic causes: multiple sclerosis, transverse myelitis, or vascular malformations

Living with Tetraplegia

While the physical impact of tetraplegia is profound, the emotional and psychological effects can be equally challenging. Individuals may experience:

• Loss of independence

• Social isolation

• Depression or anxiety

• Financial burden due to medical costs and caregiving needs

However, with advancements in medicine, rehabilitation, and assistive technology, living a fulfilling life with tetraplegia is increasingly possible.

Advances in Functional Restoration

At Tetrahand Cyprus, we focus on one of the most promising frontiers in spinal cord injury rehabilitation: functional upper limb reconstruction.

Many individuals with tetraplegia retain some degree of movement in their shoulders and arms, even if they lack hand or elbow control. This opens the door to reconstructive surgical options that can restore movement, sensation, and ultimately, functional independence.

Some of the surgical options include:

1. Tendon Transfers

Rerouting tendons from functioning muscles to perform the tasks of paralyzed ones. Examples:

• Posterior deltoid to triceps transfer (for elbow extension)

• Brachioradialis to flexor pollicis longus (for thumb flexion)

2. Nerve Transfers

Using functioning donor nerves to reinnervate non-functional muscles, potentially restoring voluntary movement in paralyzed regions.

3. Spasticity Reduction Surgery

Hyperselective neurectomies and tendon lengthenings can reduce muscle tone, allowing for better control and comfort.

4. ALPHABET Procedure

A complex combination of tendon and nerve transfers designed to restore a functional grip, offering patients the ability to grasp and release objects effectively.

Rehabilitation and Therapy

Surgery is only one part of the journey. Comprehensive postoperative rehabilitation includes:

• Physiotherapy to improve strength, endurance, and movement patterns

• Occupational therapy to re-learn daily tasks with new biomechanics

• Splinting and orthotic support as needed for joint positioning and support

• Psychological support to assist with adjustment and motivation

A multidisciplinary approach ensures that patients not only regain movement, but also learn to use it meaningfully in daily life.

Assistive Technology and Devices

Even before or alongside surgery, individuals with tetraplegia benefit from a wide range of assistive devices:

• Voice-controlled smart devices

• Powered wheelchairs with sip-and-puff control

• Environmental control units (ECUs)

• Adaptive utensils and tools for daily tasks

• Exoskeletons and robotic arms (emerging technologies)

These technologies can greatly enhance autonomy and reduce dependency on caregivers.

Frequently Asked Questions

Can someone with tetraplegia ever walk again?

While walking may not be realistic for most, many can achieve significant upper limb function, which can dramatically improve quality of life. Technologies like nerve transfers, tendon transfers, and robotics offer exciting possibilities.

Is there a cure for spinal cord injury?

There is currently no full “cure,” but function can be restored through surgical and technological interventions. Research is ongoing in fields like stem cell therapy and neuroprosthetics.

What is the difference between complete and incomplete injury?

• Complete SCI: No motor or sensory function below the level of injury

• Incomplete SCI: Some preserved movement or sensation remains

This classification affects the prognosis and treatment planning.

Conclusion: A Future with Possibility

Tetraplegia can be a life-changing diagnosis—but it is not the end of possibility. Through innovation, rehabilitation, and a compassionate, personalized approach, people with spinal cord injuries can reclaim control over their lives.

At Tetrahand Cyprus, we are proud to be part of that journey—offering hope, skill, and world-class care to every patient who walks through our doors.
