June 25th is World Scoliosis Day, a date dedicated to raising awareness about this spinal condition, promoting early diagnosis, and giving visibility to those living with it.
Scoliosis is a musculoskeletal condition characterised by a lateral deviation of the spine. It presents in different forms depending on its origin, age of onset, or affected region of the spine. When it cannot be attributed to a known cause, it is referred to as idiopathic scoliosis.
Globally, adolescent idiopathic scoliosis accounts for the majority of cases diagnosed during the growth spurt.
Filum Disease as a possible cause of idiopathic scoliosis
With over 40 years of clinical experience, our team of neurosurgeons believes that Filum Disease plays a key role in the origin and progression of many idiopathic scoliosis cases, while acknowledging the influence of other associated factors.
According to the Caudal Traction Theory, developed by Dr. Miguel B. Royo Salvador, idiopathic scoliosis would be the result of an adaptive or compensatory mechanism of the spine in response to caudal spinal cord traction exerted by a tense filum terminale – an alteration usually undetectable through conventional diagnostic tests.
Risk factors associated with the progression of scoliosis
Various factors can influence the onset or progression of scoliosis:
- Family history of Filum Disease and related conditions.
- Childhood and adolescence.
- Female gender.
- Curvatures greater than 30-40 degrees, especially when the effect of gravity on the deformity is added.
- Sudden increase in spinal cord traction due to traumatic or developmental factors.
Impact of scoliosis on quality of life
On World Scoliosis Day, it is essential to highlight the significant impact this condition can have on the quality of life of those who suffer from it.
In addition to the spinal deformity, many patients experience:
- Altered self-image and self-esteem.
- Persistent or chronic pain.
- Functional limitations.
- Difficulties arising from the prolonged use of braces or other support systems.
- Emotional and psychological impact, especially during adolescence.
All these factors shape patient expectations and influence their perception of treatment outcomes.
Diagnosis of scoliosis and detection of signs of spinal cord traction
An accurate diagnosis is essential for determining the most appropriate treatment.
The assessment typically includes:
- Standing frontal and lateral full spine X-rays.
- Magnetic resonance imaging (MRI) of the spine.
- Specialist clinical evaluation.
These tests allow for the identification of possible signs of spinal cord traction and help determine whether Filum Disease may be related to the observed spinal deviation.
Scoliosis treatment with the Filum System ® method
When signs consistent with spinal cord traction are identified in patients with scoliosis, our specialists may recommend surgical treatment using the Filum System® method.
This approach involves Sectioning of the Filum Terminale, an exclusive minimally invasive technique associated with low risks and a low rate of complications. Its objective is to eliminate the traction considered the primary cause of spinal deviation and to help slow the progression of the curvature.
Personalised post-operative care
Following the procedure, the medical team establishes an individualised treatment plan that may include:
- Specialised rehabilitation.
- Corrective muscle stimulation.
- Physical therapy.
- Use of an orthopaedic brace.
- Spinal fusion, when indicated.
Outcomes observed in patients with mild idiopathic scoliosis
In numerous patients with mild idiopathic scoliosis, the following has been observed:
- Spontaneous resolution of the scoliotic posture.
- Partial correction of the spinal curvature.
- Greater effectiveness of rehabilitation and physical therapy programmes.
Regarding the progression of the deformity:
- Curvatures between 10° and 40°: progression usually stops.
- Curvatures greater than 40°: may continue to progress due to gravity or other mechanical factors, although generally at a slower rate since the primary cause of traction has been eliminated.
Awareness and early intervention: key points on World Scoliosis Day
World Scoliosis Day reminds us of the importance of early detection, specialized follow-up, and the pursuit for treatments that address the underlying cause of the condition. Early medical evaluation can contribute to improving the prognosis and quality of life of individuals with scoliosis.
