| 50 year-old woman with a distal radius immobilized by 4 Kirschner wires (K-wires). There is also an ulnar styloid fracture. |
Note the different screw pitch on each end. Also known as headless (recessed) fixation screws. From Taljanovic, 2005 |

The scaphoid has been removed. The spider plate transfixes the lunate, triquetrum, capitate, and hamate which are partially fused. From Taljanovic, 2005 |

| This is also commonly called a "volar" fixation plate. From Taljanovic, 2005 |
64 year-old woman with thumb "tightrope" surgery using Endobuttons and Acutrak screws. The trapezium has been resected. |

|
| The Accutrak screws are used for arthrodesis of the distal interphalangeal joints of the right index and long fingers in a woman with severe osteoarthritis. |
47 year-old man with fracture of the left little finger proximal phalanx. |
Interference (Kurosaka) screws are used to anchor anterior cruciate ligament graft in femoral and tibial metaphysis. Note the multiple osteochondromas (familial exostosis). From Hunter, 1994 |

| Multiple suture anchors are present in the left shoulder humeral head for tacking down the joint capsule in a patient with recurrent shoulder dislocation. |

Flexible intramedullary fixation rods stabilize a healing humerus shaft fracture. The wire in the eyelets distally (arrow) prevent the rods from backing out of the insertion portal. From Hunter, 1994 |

| Tension band fixation of an olecranon fracture using a cancellous screw. The looped wire transforms the distractive pull of the triceps into compression at the fracture site. From Hunter, 1994 |

The carbon fiber fixation plate itself is radiolucent but has a wire encased in it to allow radiographic evaluation of its placement. In the proximal end of the plate are 3.5 mm proximal humeral head fixed angle threaded locking holes with 3.5 mm locking screws.
