Orthopedics

Orthopedics

  • Is the study of the musculoskeletal system.


Ctvt pgs 676 677 retractors and pgs 679 685

CTVT: pgs 676-677-Retractors and pgs 679-685

  • Please review all information on orthopedic instruments.

  • You will be given an instrument identification exam over orthopedic instruments.

  • Please take time to study the orthopedic instruments here at school as well as in your book.


Orthopedic surgery

Orthopedic Surgery

  • Is the branch of surgery concerned with acute, chronic, traumatic, and overuse injuries and other disorders of the musculoskeletal system. Orthopedic surgeons address most musculoskeletal ailments including arthritis, trauma and congenital deformities using both surgical and non-surgical means.

Answer

Bones

Joints

Ligaments

Tendons

Muscles

Nerves

Cartilage

Answer:


Orthopedics

Wire cutters (left) and bone cutters (right). They look similar but should not be confused. Bone cutters have finer jaws.


Orthopedics

Chisel

Osteotomes and chisels are used to cut bone. Osteotomes and chisels are used by pounding on the flared end of the handle with a mallet.

  • Intervertebral Disk Disease


Orthopedics

Jacobs hand chuck

or a power drill

is required to

insert pins into

bone, and a pin

cutter is necessary

to cut it to the

proper length.

Orthopedics

Bone-holding forceps. Left to right: Small Kern bone-holding forceps, large speed-lock forceps, large point-to-point forceps, small clamshell forceps.


Orthopedics

Bone curettes of various sizes.

Used to scrape hard tissue such as bone or cartilage. Notice the cuplike structure. These are used for bone grafts.


Orthopedics

In general these instruments

are called Periosteal

elevators

Freer

elevator

¼ inch Key elevator

Used to pry periosteum or muscle from the bone surface. They can have sharp or blunt edges and are available in various sizes.


Michel trephine

Michel trephine

This instrument is T-shaped and is used to remove a core of bone for biopsy. All of these instruments are very sharp. Use caution when handling them.


Orthopedics

Orthopedic wire, wire twisters, wire cutters. Wire twisters look similar to needle holders but are more rugged and designed to withstand higher forces.


Various sizes of bone plates

Various sizes of bone plates.

Bone plates must be bent to match the curve of

the bone and fastened to it with bone screws.

Orthopedics

Bone plating equipment. Left to right: Drill guide, drill bit, depth gauge, tap sleeve (to prevent soft tissues from being caught on the bone tap), bone tap, and screwdriver.


Orthopedics

External fixation is a means of stabilizing fractures using pins placed through the skin and bone. These pins are fixed to bars using special clamps.

  • Please read over the following topics:

    • Canine Hip Dysplasia

    • Intervertebral Disc Disease


Canine hip dysplasia

Canine Hip Dysplasia

Hip dysplasia is an abnormal development and growth of the hip joint. Both hips are usually affected, but only one side may show symptoms. Hip dysplasia occurs primarily in dogs that have a mature body weight of over 30 pounds. Genetics and nutrition appear to important factors in these dogs.


Intervertebral disk disease

Intervertebral Disk Disease

  • Breeds commonly affected:

    • Dachshunds

    • Pekingese

    • Cocker Spaniels

    • Poodles

    • Pugs

    • Beagles


Chondrodystrophoid

Chondrodystrophoid

  • Any disorder of cartilage formation

Intervertebral disk disease affects the spinal cord of chondrodystrophoid breeds at an earlier age than nonchondrodystrophoid breeds.
