Study Notes
Orthopedic Surgery Overview
- Orthopedic surgery addresses musculoskeletal disorders and relies on advanced technology to improve patient outcomes.
- Understanding bone and tissue fixation is crucial for perioperative nursing to ensure optimal patient care.
Anatomy of the Skeletal System
- Composed of 206 bones, muscles, ligaments, tendons, and cartilage.
- Bones facilitate movement, support soft tissues, act as mineral reservoirs, and generate blood cells.
- Muscles provide movement; ligaments connect bones; tendons connect muscles to bones or cartilage.
Types of Bone Tissue
- Cortical Bone: Hard outer layer providing structural support.
- Cancellous Bone: Soft, spongy inner tissue, containing red bone marrow.
Vertebral Column Structure
- Comprised of 7 cervical, 12 thoracic, and 5 lumbar vertebrae, along with the sacrum and coccyx.
- Vertebral bodies are connected by cartilage joints, enabling mobility.
Perioperative Nursing Considerations
- Correct side and site marking is vital for surgical accuracy, confirmed via surgical safety checklist and x-rays.
- Aseptic techniques are essential in orthopedic procedures.
Patient Positioning
- Depends on the procedure; common positions include supine, lateral, Fowler's, and prone.
- Special aids are utilized for lateral positioning; proper padding is crucial for spinal surgeries.
Draping and Instrumentation
- Draping varies based on the procedure and surgeon preferences, typically limb draping is used.
- Basic orthopedic instrument sets include periosteal elevators, retractors, and bone rongeurs.
Bone Fixation Sequence
- Stabilize the fracture with a bone holder.
- Drill to create a hole for the screw.
- Tap the hole to ensure a stable canal.
- Measure screw depth using a depth gauge.
- Insert the screw with a screwdriver.
Prosthetic Joint Replacement
- Used in cases of degenerated or fractured joints, commonly in the hip, knee, and shoulder.
- Dynamic compression plates and screws are utilized to stabilize fractures and promote healing.
Arthroscopy
- Minimally invasive diagnostic and operative technique, mainly for knee, shoulder, and wrist surgeries.
- Involves saline irrigation and small incisions for instruments and scope insertion.
Hip Fractures
- Classified into three types: Femoral Neck, Intertrochanteric, and Subtrochanteric.
- Intertrochanteric fractures are common in elderly women and can be fixed with plates and screws.
Surgical Equipment for Hip Surgery
- OR Fracture Table: For positioning and stabilization.
- Common instruments include the Dynamic Hip Screw (DHS) for fixation.
Femoral Neck Fractures
- Require careful reduction to prevent complications such as necrosis.
- Blood supply can be compromised, necessitating specific surgical strategies.
Spinal Surgery Considerations
- Patients positioned prone with specific care to prevent injury.
- Common equipment includes spinal instrumentation, bone graft instruments, and fluoroscopy for guidance.
Hand Surgery
- Carpal Tunnel Release: Involves dividing the carpal ligament to relieve median nerve pressure.
- Typically performed under local anesthetic or Bier block utilizing a tourniquet.
