Scoliosis is a medical condition characterized by an abnormal sideways curvature of the spine, which can appear as an “S” or “C” shape when viewed from the back. It can affect individuals of all ages, but it is most commonly diagnosed in adolescents. For moderate or mild curves that are at risk of worsening, bracing is a common non-surgical treatment option. These custom-made devices are designed to fit around the torso, applying pressure to the spine.
Purpose of Bracing
Scoliosis braces primarily prevent spinal curve progression, especially during rapid growth in children and adolescents. They apply pressure to halt or slow the curve’s progression, helping prevent the need for surgical intervention. While not correcting existing curves, braces aim to keep the Cobb angle, a measure of spinal curvature, small and manageable. Bracing can also improve spinal alignment as the individual grows.
Factors Determining Brace Wear Duration
The total time an individual wears a scoliosis brace depends on several factors: patient age and skeletal maturity, curve severity at diagnosis, scoliosis type, and adherence to the prescribed protocol. Skeletal maturity is a significant determinant, often assessed using methods like the Risser sign, which indicates how much growth remains. A lower Risser score suggests more growth potential and a higher risk of curve progression, potentially requiring longer bracing.
The initial curve severity, measured by the Cobb angle, also influences brace duration. Bracing is typically recommended for curves between 20 and 40 degrees, especially if progression is observed or anticipated. Curves exceeding 40 degrees may still benefit from bracing, though effectiveness may decrease. The type of scoliosis, such as adolescent idiopathic scoliosis, and its progression rate also guide treatment length. Consistent adherence to the bracing schedule is important, as studies suggest that wearing the brace for the recommended hours significantly impacts its effectiveness.
Typical Brace Wear Timelines
Bracing typically continues until skeletal maturity is reached, as the brace influences a still-growing spine. For many patients, particularly adolescents, this can mean wearing a brace for several years. Teenagers often wear braces for an average of 26 months, while younger children (ages 4-10) may require treatment for many years.
Once bone growth has ceased, confirmed by X-rays and skeletal maturity indicators like a Risser score of 4 or 5, the brace can typically be removed. For girls, this often aligns with being at least two years past the onset of their menstrual cycle. While these are general guidelines, individual treatment plans are tailored, and a healthcare provider monitors growth and curve stability to determine the optimal end point for bracing.
Daily Brace Wearing Schedule
The daily commitment to wearing a scoliosis brace is important for its effectiveness. Most full-time rigid braces are prescribed for 16 to 23 hours per day, allowing short breaks for activities such as showering or sports. Studies indicate that wearing the brace for a minimum of 18 hours daily demonstrates maximum efficacy.
Some cases, especially those with milder curves or when full-time bracing is not feasible, may involve part-time or nighttime-only bracing. For example, Charleston bending braces or Providence braces are often worn for about eight hours daily, typically during sleep. Consistent adherence to the prescribed daily wear time is important for preventing curve progression.
Transitioning Out of the Brace
Once skeletal maturity is largely achieved and the spinal curve has stabilized, transitioning out of the brace usually begins. This is often a gradual process, designed to allow the spine to adapt. Weaning protocols can vary, but commonly involve progressively reducing daily wear time over several months, sometimes shifting to night-time only wear.
This transition period requires careful monitoring, as some curve progression is possible after brace cessation. Continued observation, often through regular check-ups and X-rays, is important to ensure the curve remains stable post-bracing. Some research suggests that continuing scoliosis-specific exercises during the weaning phase can help maintain correction and reduce the risk of regression.
