Spine Surgery is a field dedicated to the evaluation and treatment of conditions affecting the vertebrae, intervertebral discs, joints, ligaments, spinal cord and nerves associated with the spine.
These conditions may cause pain, limited mobility, tingling, changes in sensation, muscle weakness and difficulty walking. However, not every abnormality identified on an imaging test is responsible for the patient’s symptoms, and not every spinal condition requires surgery.
A specialized evaluation seeks to understand the relationship between the patient’s symptoms, the physical and neurological examinations and the findings observed on imaging studies. Based on this analysis, it is possible to define a treatment plan that is appropriate for the severity and characteristics of each case.
Spine Surgery covers a wide range of conditions and abnormalities, including:
• Herniated discs
• Lower back pain
• Neck pain
• Pain radiating to the arms or legs
• Spinal canal stenosis
• Scoliosis and other spinal deformities
• Spinal instability
• Compression of the spinal cord or nerve roots
• Tumors of the spine and spinal cord
• Degenerative spinal conditions
Each condition has its own characteristics and may require a different monitoring or treatment strategy.
A herniated disc occurs when part of the disc located between the vertebrae moves out of position and may irritate or compress nearby nerve structures.
In the lumbar spine, it may cause back pain, pain radiating to the legs, tingling, numbness or muscle weakness. When it affects the cervical spine, symptoms may extend to the neck, shoulders, arms and hands.
Many cases can initially be managed with medication, physical therapy, rehabilitation and adjustments to daily activities. Surgery may be considered when symptoms persist despite appropriate treatment, when neurological impairment is present or when quality of life is significantly affected.
Lower back pain affects the lower region of the back. Neck pain affects the cervical region.
These symptoms may be related to muscular changes, physical strain, joint degeneration, herniated discs, stenosis, instability or other conditions.
The intensity of the pain alone does not determine the severity of the condition. The duration of symptoms, radiating pain, functional limitations and the presence of neurological changes must also be considered.
Pain that begins in the spine and extends to the limbs may indicate irritation or compression of a nerve root.
In the lumbar region, this is often experienced as sciatica. In the cervical region, pain may extend to the shoulders, arms, hands and fingers.
Tingling, numbness, electric shock-like sensations or muscle weakness may also occur. The evaluation seeks to identify the location of the compression and understand its impact on neurological function.
Spinal stenosis is the narrowing of the space through which the spinal cord or spinal nerve structures pass.
In the lumbar region, it may cause pain, weakness, numbness and difficulty walking for extended periods. In the cervical spine, it may cause balance problems, reduced hand dexterity, tingling and muscle weakness.
Mild or moderate cases may be monitored and treated conservatively. Surgery may be considered when there is significant limitation, progression of symptoms or neurological impairment.
Scoliosis and other deformities alter the alignment of the spine and may affect posture, balance and the distribution of pressure across the spinal structures.
Instability occurs when there is excessive or abnormal movement between the vertebrae.
The evaluation considers the patient’s anatomy, progression of the deformity, presence of pain, neurological changes and impact on daily activities.
Treatment may involve monitoring, rehabilitation, muscle strengthening or surgery in selected cases.
Tumors may affect the vertebrae, spinal cord, membranes surrounding the nervous system or nearby structures.
Symptoms may include persistent pain, worsening pain at night, muscle weakness, tingling, loss of sensation and difficulty walking.
The diagnostic process may involve imaging studies and additional evaluations to understand the nature and extent of the lesion. Treatment planning considers the diagnosis, location and the need to preserve neurological function.
The consultation begins with an analysis of the patient’s symptoms, the limitations caused by pain and any previous treatments.
The physical and neurological examination assesses strength, mobility, sensation, reflexes, balance and gait.
When necessary, imaging tests help identify structural abnormalities. Treatment decisions are based on the complete set of information rather than solely on the results of an MRI or CT scan.
Many spinal conditions can initially be treated without surgery.
The approach may include medication, physical therapy, rehabilitation, muscle strengthening, activity adjustments and monitoring of the patient’s progress.
Treatment is adjusted according to the patient’s response. If symptoms persist, progress or are accompanied by neurological changes, a new evaluation may be necessary.
Endoscopic spine surgery uses a camera and delicate instruments to access certain spinal structures through small incisions.
It may be considered in selected cases of herniated discs and other conditions that cause nerve compression.
The indication depends on the location of the abnormality, the patient’s anatomy and the objectives of the procedure. Not every spinal condition can be treated using this technique.
Not every spine surgery requires the placement of screws or other stabilization devices.
In some cases, the objective is only to decompress the spinal cord or nerves. In others, the presence of instability, deformity or the need for spinal fusion may make instrumentation necessary.
The choice must be individualized and based on clinical, neurological and anatomical criteria.
Persistent pain, radiating symptoms, tingling, muscle weakness, difficulty walking and progressive limitations in daily activities may indicate the need for an evaluation.
Sudden or progressive muscle weakness, changes in bladder or bowel control and numbness in the genital or inner thigh area require immediate medical attention.
