When splinting a deformity in the lower leg, where should the splint extend to?

When splinting a deformity in the lower leg, it is crucial for the splint to extend above the knee to below the foot. This extension is necessary because it provides adequate support and stabilization to the entire leg, particularly in cases of fractures or severe injuries involving the femur and knee joint. By including the knee in the splinting process, you help prevent further injury and assist in maintaining proper alignment and immobilization.

A splint that does not extend high enough may allow for movement at the knee or upper leg, which can exacerbate any existing injuries or lead to complications. Similarly, extending the splint only to the ankle or within limited areas does not offer the requisite support for serious lower leg injuries. Therefore, the correct approach is to ensure that the splint encompasses the area from above the knee, all the way down to below the foot, to effectively manage and immobilize any deformity in the lower leg.
