Rods and nails support the bone while it heals, which allows patients to put weight on the leg or arm faster. What are the advantages of using a rod or nail? For the humerus (upper arm bone), the device will be inserted through the top of the humerus that is closest to the shoulder (from the shoulder towards the elbow).For the tibia (shin bone), the device will almost always be inserted through the top of the tibia that is closest to the knee (inserted from the knee towards the ankle).Through the bottom of the femur that is closest to the knee (inserted from the knee towards the hip).Through the top of the femur that is closest to the hip (inserted from the hip towards the knee).For the femur (thigh bone), the device may be inserted in two different ways:.The way the rod or nail is inserted depends on the bone and the patient’s unique situation: This canal will be large enough for the nail or rod to fit inside it. The doctor will use an orthopedic drill to create a canal in the marrow cavity in the center of the bone. The outer part of a bone is made up of hard tissue, but the inside of a bone is made up softer marrow tissue. How is a nail or a rod inserted into the center of a bone?įirst, the doctor needs to make space for the device to fit inside the bone. Depending on the clinical scenario, our surgeons may use Rush rods and/or antibiotic cement-coated rods. Rods tend to be more flexible and thinner than nails. Rods are inserted inside the bone but are not attached to the bone with bone screws or pins. They increase the stability of the nail inside the bone. Bone screws or pins are inserted through these holes and are then attached to the bone. A nail has small holes drilled at both ends of the nail. Nails and rods are both inserted into the center of the bone, but only nails are attached to the bone with cross bolts or locking screws. What is the difference between a rod and a nail? Special types of nails and rods can also be used to deliver antibiotics to an infected bone. A nail or rod can be used to stabilize a bone after deformity correction or after a fracture so that the bone is held steady and protected while it heals. Nails can be used to lengthen bones or to assist with lengthening bones. The doctor may interchangeably refer to rods and nails as internal, intramedullary, or IM devices. They are also called intramedullary (IM) devices, as they go inside of the bone. These devices are inserted inside the marrow cavity of a long bone (tibia, femur, humerus, or forearm bones). Rods and nails are long cylinders that are made of surgical grade metal (stainless steel or titanium). Share Tweet Email Print What are rods and nails?

LIPUS likely has the ability to enhance maturation of the callus in distraction osteogenesis and reduce the healing index. For delayed union and nonunion, the overall success rate of LIPUS therapy is approximately 67% (humerus), 90% (radius/radius-ulna), 82% (femur), and 87% (tibia/tibia-fibula). The incidence of delayed union and nonunion is 5% to 10% of all fractures. The beneficial effect of acceleration of fracture healing by LIPUS is considered to be larger in the group of patients or fractures with potentially negative factors for fracture healing. Some literature, however, has shown no positive effects. They showed that LIPUS accelerated the fracture healing rate from 24% to 42% for fresh fractures. In 19, two milestone double-blind randomized controlled trials revealed the benefits of LIPUS for the acceleration of fracture healing in the tibia and radius. It has a frequency of 1.5 MHz, a signal burst width of 200 micros, a signal repetition frequency of 1 kHz, and an intensity of 30 mW/cm2. Low-intensity pulsed ultrasound (LIPUS) is a relatively new technique for the acceleration of fracture healing in fresh fractures and nonunions.
