What is the standard lateral inferior trimline for a single piece anterior opening custom LSO?

The standard lateral inferior trimline for a single piece anterior opening custom lumbar sacral orthosis (LSO) is typically set at 2 cm or 3/4 inch superior to the greater trochanter. This measurement is crucial for ensuring that the orthosis fits appropriately and provides adequate support without restricting mobility excessively. Positioning the trimline in this location helps in achieving a good balance between stabilization of the lumbar region and accommodating the anatomical structure of the hip and pelvis.

By aligning the trimline correctly, the orthosis can provide necessary spinal support while allowing for the proper movement of the legs during activities. This consideration is essential in optimizing the overall functionality and comfort of the orthosis for the patient, promoting better adherence to wearing the device and enhancing the overall therapeutic outcome.
