What modification should be made to a scoliosis orthosis for hypokyphosis?

The appropriate modification for a scoliosis orthosis in the context of hypokyphosis involves extending the posterior superior trimline to T3. Hypokyphosis is characterized by an insufficient curve in the thoracic region of the spine, leading to a more flattened thoracic posture. By extending the posterior superior trimline up to T3, the orthosis can provide targeted support to the upper thoracic spine, which is crucial for enhancing the kyphotic curve necessary for optimal spinal alignment.

This modification assists in promoting a more natural thoracic curve, helping to alleviate discomfort and improve functional mobility. Reaching up to T3 allows for proper positioning and support that influences the entire thoracic region, which is essential in managing the condition effectively.
