| Bone Plates |
Stainless steel, titanium, or titanium alloy |
Provide rigid or semi-rigid fixation across a fracture. |
Long-bone fractures, periarticular fractures, osteotomies, and corrective procedures. |
Maintain alignment and limit movement between fracture fragments while bone healing occurs. |
Plate selection depends on fracture pattern, bone quality, anatomical location, and required fixation strength. |
| Bone Screws |
Stainless steel, titanium alloy, or bioabsorbable polymers in selected applications |
Attach plates to bone or compress and secure individual fracture fragments. |
Fracture fixation, lag-screw compression, fragment fixation, and attachment of fixation plates. |
Generate compression or hold implants firmly in bone to prevent loss of reduction. |
Thread design, diameter, length, and purchase in the bone must match the anatomy and surgical objective. |
| Intramedullary Nails |
Titanium alloy or stainless steel |
Stabilize fractures from within the medullary canal. |
Femoral, tibial, and humeral shaft fractures; selected metaphyseal and segmental fractures. |
Share load along the bone axis and help control shortening, rotation, and angulation. |
Often combined with locking screws; correct nail diameter, length, and entry point are important. |
| Locking Bolts and Interlocking Screws |
Titanium alloy or stainless steel |
Lock an intramedullary nail to the bone. |
Unstable shaft fractures, comminuted fractures, and fractures requiring control of rotation or length. |
Prevent migration of the nail and control axial and rotational movement of fracture segments. |
Number and position of locking screws depend on fracture stability and the selected fixation strategy. |
| External Fixator Components |
Metal pins, rods, clamps, rings, and carbon-fiber or metal connecting elements |
Stabilize a fracture using a frame outside the body. |
Open fractures, severe soft-tissue injury, temporary damage-control stabilization, and complex limb reconstruction. |
Transfers stabilizing forces through percutaneous pins or wires while allowing access to injured soft tissue. |
Pin-site care, frame alignment, and protection of nearby nerves and blood vessels are essential. |
| Kirschner Wires and Steinmann Pins |
Stainless steel or titanium alloy |
Provide temporary or definitive fixation of small bone fragments and selected fractures. |
Hand and foot fractures, pediatric fractures, small-joint procedures, and temporary intraoperative fixation. |
Maintain fragment position or guide other implants during fracture repair. |
They may be smooth or threaded; exposed wires require careful protection and monitoring for infection. |
| Cerclage Wires and Cables |
Stainless steel or cobalt-chromium alloy |
Wrap around bone to hold fragments together or supplement another fixation method. |
Longitudinal fractures, trochanteric fixation, revision procedures, and selected periprosthetic fractures. |
Apply circumferential compression and help prevent fragment separation. |
They are generally used as an adjunct rather than the sole fixation method for many unstable fractures. |
| Bone Graft Materials |
Autologous bone, donated human bone, or processed synthetic graft substitutes |
Fill bone defects and support biological healing. |
Nonunion, bone loss, spinal fusion, revision surgery, and defects created during reconstruction. |
May provide osteogenic cells, osteoconductive scaffolding, or osteoinductive signals, depending on the material. |
Choice depends on defect size, patient factors, biological needs, and infection risk. |
| Bone Cement |
Polymethyl methacrylate (PMMA) |
Fill gaps and provide mechanical fixation in selected orthopedic procedures. |
Fixation of certain joint replacement components, vertebral augmentation, and antibiotic-loaded spacers in staged treatment. |
Creates a mechanical interlock between an implant and prepared bone or stabilizes weakened bone in selected procedures. |
It does not biologically bond to bone; heat generated during curing and cement-related complications must be considered. |
| Suture Anchors |
Metal, bioabsorbable polymers, or composite materials |
Secure sutures to bone for reattachment of soft tissues. |
Repair of tendons, ligaments, labral tissue, and other soft-tissue attachments around joints. |
Restore the connection between soft tissue and bone, supporting functional recovery rather than directly bridging a fracture. |
Anchor size, placement, pullout strength, and material absorption profile vary by anatomy and procedure. |
| Spinal Rods, Screws, and Interbody Devices |
Titanium alloy, cobalt-chromium alloy, stainless steel, or radiolucent polymer composites |
Align and stabilize spinal segments and, in selected procedures, support fusion. |
Spinal deformity correction, instability, degenerative conditions, trauma, and reconstruction after decompression. |
Control spinal motion and alignment while bone graft material may bridge the intended fusion area. |
Implant configuration is based on spinal level, bone quality, alignment goals, and the planned fusion technique. |
| Orthopedic Casts and Splints |
Plaster of Paris, fiberglass, foam, thermoplastics, and padding |
Restrict movement and protect an injured or surgically repaired area. |
Fracture immobilization, postoperative protection, sprains, and temporary stabilization before definitive treatment. |
Reduce stress on the injured bone and surrounding tissues while early healing takes place. |
Fit must be monitored for swelling, pressure injury, impaired circulation, numbness, or worsening pain. |
