Wee ROM is specially developed for children. It is used after operations or injuries to support, immobilize or regulate the range of motion in the legs and knee joints. By telescopic adjustment of the upper and lower leg rails, it can be easily adjusted. The distal ankle part must be placed above the malleolus which prevents the orthosis from sliding and ensures the limitation of movement in the knee joint. Extension and flexion can be adjusted between -10° to 110° in 10° increments. It can also be immobilized via a quick lock button. The orthosis is open, airy, and comfortable.
