  • Weightbearing orthoses - This orthosis is designed to eliminate weight bearing through the lower extremities. Weightbearing orthoses consist of patellar-tendon–bearing orthosis (PTBO), ischial weightbearing orthosis, and patten bottom with uprights terminated in a floor pad or patten distal to the shoe.
  • Fracture orthoses - This orthosis stabilizes the fracture site and promotes callus formation, while allowing weight bearing and joint movement after initial subsiding pain and edema. The bony motion at the fracture site is prevented through circumferential compression of the soft tissue. Fracture orthoses include the tibial fracture orthosis and femoral fracture orthosis.
  • Angular and deformity orthoses - This orthosis is used in the pediatric population. The Denis Brown splint is for clubfoot. A frame orthosis applies corrective forces to proximal rotational deformities. A torsion shaft orthosis is used in mild scissoring gait of spastic diplegia.
  • Congenital hip dislocation orthoses - These devices, such as the Pavlik harness, Ilfeld splint, and Von Rosen splint, are used to maintain the hip in flexion and abduction position to hold the femoral head within the acetabulum.
  • The Scottish Rite, Toronto, and non–skeletal-bearing trilateral orthoses - These are used in Legg-Calve-Perthes disease to maintain the hip in abduction and keep the femoral head in the acetabulum.
