What orthosis is used at mid lumbar L3?

Explanation:
At mid-lumbar level L3, the knee joint can still be functionally controlled (quadriceps function is typically present), so the orthosis chosen should provide stabilization for both the knee and the ankle to support safe standing and walking. A knee-ankle-foot orthosis spans from thigh to foot and includes a knee joint that can be locked for stability, giving the necessary knee control during gait while also supporting the ankle and foot. An AFO would address only the foot and ankle and leave the knee unstable, which is not ideal at this level. A TLSO is intended to immobilize the upper spine and trunk, which isn’t needed for an L3-level lesion, and a HALO is for cervical spine immobilization, not relevant here.
