On which side should the trochanteric extension of an orthosis be placed?

The trochanteric extension of an orthosis is crucial for providing adequate support and alignment to the pelvis and hip joint, which can greatly influence overall gait and stability. It is placed on the side of decompensation, as its primary purpose is to assist with controlling pelvic tilt and maintaining proper alignment in individuals who have experienced instability or dysfunction on that side.

When the body compensates for issues such as weakness or deformity, the alignment of the hip and pelvis may be altered, resulting in a compensation pattern. Implementing the trochanteric extension on the decompensated side helps to stabilize that side, thus preventing further misalignment and assisting in effective weight-bearing during ambulation.

This placement supports biomechanical efficiency and encourages symmetrical movement patterns. The other options, such as placing it on the side of compensation or the midline, do not serve the intended purpose of correcting decompensations effectively. Additionally, relying on patient preference for placement could lead to inadequate support, resulting in further complications or ineffective use of the orthosis.
