Intended Use

Intramedullary rods made of titanium alloy are used for the same indications as stainless steel intramedullary rods that have been commercially available continually since the 1950s. These devices are to be implanted into the long bones for alignment, stabilization and fixation of fractures caused by trauma or disease, the fixation of long bones that have been surgically prepared (osteotomy) for correction of deformity, and for arthrodesis. Intramedullary rods are used in the femur, tibia, fibula, humerus, radius, and ulna.

Device Story

Titanium intramedullary rods; rod-shaped implants with optional screw holes; inserted into medullary canal of long bones (femur, tibia, fibula, humerus, radius, ulna). Used by surgeons for fracture fixation, osteotomy stabilization, and arthrodesis. Provides mechanical alignment and stabilization of bone fragments; transverse screws may be added for additional stability. Benefits include internal fixation of fractures and deformities. Risks include nonunion, implant breakage, loosening, migration, metal sensitivity, and surgical complications.

Clinical Evidence

No clinical data. Substantial equivalence is based on design and functional similarity to predicate devices with long-standing clinical history.

Technological Characteristics

Materials: Titanium 6Al-4V alloy. Form factor: Rod-shaped with optional screw holes. Principle: Mechanical internal fixation. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring alignment, stabilization, and fixation of long bone fractures (femur, tibia, fibula, humerus, radius, ulna) caused by trauma or disease, fixation of osteotomies for deformity correction, and arthrodesis.

Regulatory Classification

Identification

An intramedullary fixation rod is a device intended to be implanted that consists of a rod made of alloys such as cobalt-chromium-molybdenum and stainless steel. It is inserted into the medullary (bone marrow) canal of long bones for the fixation of fractures.

Device. Titanium Intramedullary Rods - Various Styles

Classification Name. Rod, Fixation, Intramedullary and Accessories (CFR 888.3020)

Device Description. Intramedullary rods are generally rod-shaped devices with or without screw holes at either end for fixation to bone. These devices are intended to be inserted into the medullary (bone marrow) canal of long bones for the fixation of fractures by aligning and stabilizing the bone fragments. Intramedullary rods are also used to align and stabilize long bones which are surgically cut (osteotomy) to correct deformity. Additional stabilization may be realized by installing transverse screws through holes in the rod. Intramedullary rods and transverse screws are made of titanium 6Al-4V alloy.

Intramedullary rods are used in the femur, tibia, fibula, humerus, radius, and ulna.

Potential Risks. The risks associated with this device are the same as with any metallic internal fixation device. These include but are not limited to the following.

Delayed or nonunion which may lead to breakage of the implant

Bending or fracture of the implant

Loosening or migration of the implant

Metal sensitivity, or allergic reaction to a foreign body

Limb shortening or decrease in bone density due to compression of the fracture or bone resorption

Pain, discomfort, or abnormal sensations due to the presence of the device
