Reduction/Internal Fixation and Amputation Procedures



FIG. 7.20 A, Comminuted displaced intraarticular distal radius fracture (a.k.a. Colle fracture). B, After open reduction and internal fixation (ORIF) surgery with anatomic alignment. (From Donatelli RA, Wooden MJ: Orthopaedic physical therapy, ed 4, St Louis, 2010, Churchill Livingstone.)



• Bunionectomy (Keller, Austin)


• Triple arthrodesis


• ORIF of tibia


• ORIF of fibula

Basic Anatomy Affected



• All short and long bones


• Cancellous and cortical bone

Basic Equipment Required



• Fracture table


• Special arm board


• Imaging equipment: fluoroscopy, C-arm, image intensifier


• Power equipment: drill, saw, reamer


• Tourniquet (Esmarch)


• Minor and major orthopedic instrument sets


• Fixation implants: screws, plates, prosthesis


• Draping: extremity drape, split sheet, stockinette as needed


• Polymethylmethacrylate bone cement


• Scavenging system


• Screws: cancellous, cortical, cannulated


• Gigli saw


• Spacesuit/hood

Additional Facts to Remember



• Remember to verify that the correct implants are available and have been supplied before the patient is brought into the surgical suite.

Monitor tourniquet time carefully.

Most screws are self-tapping, but it’s important to remember the sequence of steps in screw insertion nonetheless:

Mapping


Here’s the map for one common orthopedic surgery.

 


Surgical Mapping

ORIF of hip fracture












Instruments Important Anatomy Involved Pathophysiology

Major orthopedic tray

Power equipment (drill, reamer)

Cannulated screw or DHS (dynamic hip compression) tray

Pulse lavage

Pelvis

Hip joint

Femur

Femoral head

Femoral neck

Trochanter

Acetabulum

C-arm
Hip fracture











Microbiology/Wound Classification Skin Prep/Incision/Patient position Pharmacology
Class I (clean)
Prep: beginning at hip joint, midline of abdomen on operative side up to midchest as far laterally as possible, and entire operative leg

Incision: from greater trochanter to implant site on affected leg

Draping: 4 towels; incise drape and laparotomy sheet

Position: supine on fracture table.

Warm normal saline

General anesthesia

Ready to map? Here are the remaining procedures:


• AKA (above-the-knee amputation)


• BKA (below-the-knee amputation)


• ORIF of radius


• External fixation of Colles fracture


• ORIF of humerus


• ORIF of femur (femoral nail)
