ORTHOPEDIC SURGERY

The branch of medical science concerned with disorders or

deformities of the spine and joints.

Orthopedic Terminology“Position and Movement”

Primary purposes of orthopedic surgery

1. Repair, revision, reconstruction, reattachment or removal any of the 206 bones of the skeletal structure and surrounding tissue

Bones, joints and affected muscle tissue Tendons, ligaments or cartilage

2. Accurately classify treatment Axial skeletal procedures Upper extremity procedures Lower extremity procedures Limb reattachment procedures Amputation procedures

Purposes (continued)3. Investigate, preserve and restore form and function to the

musculoskeletal structures and associated tissues of the extremities and also the spine. Treatment depends on the type of injury and the duration of necessary immobility.

The Skeleton

Function of Skeletal System

Support Protection Movement Storage Hematopoiesis -

the formation of blood cells in the living body (especially in the bone marrow)

Bone Histology

Bone is a type of connective tissue

2 Types of Bone: Dense/Compact

Bone/ Corticalhard on outside/canal on insidecomposed of Haversian Units or Osteon

Spongy/Cancellous Bone

Bone Formation

Osteogenesis is bone formation Two Types: Intramembranous Endochondral More Terms:

Osteoblast :a cell from which bone develops Osteocytes: a star-shaped cell, is the most abundant

cell found in bone. They are osteoblasts that have completed their bone-forming function and have become trapped in new bone tissue, evolving into structural bone cells and is involved in the maintenance of that bone. A mature bone cell.

Osteoclasts: cells break down and assimilate bone. They are located in minute, bony chambers called lacuna.

Intramembranous Ossification

Sheets of primitive connective tissue form at site of future bone

Primitive connective cells collect around blood vessels in these layers

Connective tissue cells differentiate into osteoblasts, which deposit spongy bone

Osteoblasts become osteocytes when bony matrix surrounds them (lacunae)

Connective tissue on surface of each developing structure forms a periosteum

Osteoblasts on the inside of periosteum deposit compact bone

Endochondral Ossification

Masses of hyalin cartilage form models of future bones

Cartilage tissue breaks down/Periosteum develops

Blood vessels and differentiating osteoblasts from the periosteum invade the disintegrating tissue

Osteoblasts form spongy bone in space occupied by cartilage

Osteoblasts become osteocytes when bone matrix completely surrounds them

Osteoblasts beneath periosteum deposit compact bone around spongy bone

Relevant anatomy

1. Skeletal system – articulated skeleton comprised of 206 bones

Axial skeleton – skull, spine and ribs Skull – includes cranial and maxillofacial bones

Cranial bones – 8 cranial bones Facial bones – 13 facial bones Middle ear bones – 6 middle ear bones Mandible – one jaw bone

Hyoid bone Vertebral column – 26 backbones

Verebral – 24 backbones: 7 cervical, 12 thoracic, and 5 lumbar

C-2 Axis: bone that

allows the head to pivot.

Axial Skeleton

Appendicular Skeleton

The appendicular skeleton consists of 126 bones in the human body which make motion possible and protects the organs of digestion, excretion, and reproduction.

The word appendicular refers to an appendage or anything attached to a major part of the body, such as the upper and lower extremities.

The appendicular skeleton has four major regions:

Pectoral Girdles(4 bones) Upper Limbs (60 bones) Pelvic Girdle(2 bones) Lower Limbs(60 bones)

Anatomy (continued)

Appendicular Skeleton Upper extremities –

shoulder, arm and hand bones of the appendicular skeletal system Pectoral girdle – four pectoral

or collar bonesScapula – two posterior collar

bonesGlenoid fossaCoracoid processAcromion process

Clavicle – two anterior collar bones

Upper limbs –arm, wrist and hand bonesHumerusRadiusulna

Lower extremities –hip and leg bones of the appendicular skeletal system Pelvic girdle

IliumPubisIschium

Lower limbs – leg and foot bonesFemurPatellaTibiaFibulaTarsalsMetatarsalsphalanges

Anatomy of a Bone

Bone Marrow

Within the long bones are two types of bone marrow: red marrow and yellow marrow.

The yellow marrow is fatty tissue.

During starvation, the body uses the fat in yellow marrow for energy.

Bone Marrow

The red marrow of some bones is an important site for blood cell production.

Here all red blood cells, platelets, and white blood cells form in adults. Red blood cells carry

oxygen and nutrients to the body tissues.

Platelets help in blood clotting.

White blood cells help fight disease and infection.

Muscles

Bone Types

Types of Joints

Joint Classification

1. Functionallybased on degree of movement*synarthroses-no movement*amphiarthroses-slight movement*diarthroses-freely moveable

2. Structurallybased on type of connective tissue and type of joint cavity*fibrous-no movement, no joint cavity, dense fibrous connective tissue, synarthoses*cartiligenous-slight to no movement, can be synarthroses or amphiarthroses*synovial-joint cavity, diarthroses

Diarthroses Joints

The 6 types of diarthroses joints:• Ball-and-Socket• Condyloid• Saddle• Pivot• Hinge• Gliding

Ball-and-Socket Joint

The ball-shaped end of one bone fits into a cup shaped socket on the other bone allowing the widest range of motion including rotation.

Examples include the shoulder and hip.

Condyloid Joint

Oval shaped condyle fits into elliptical cavity of another allowing angular motion but not rotation.

Saddle Joint

This type of joint occurs when the touching surfaces of two bones have both concave and convex regions with the shapes of the two bones complementing one other and allowing a wide range of movement.

The only saddle joint in the body is in the thumb.

Pivot Joint

Rounded surfaces of one bone fit into a ring of one or tendon allowing rotation.

An example is the joint between the axis and atlas in the neck.

Hinge Joint

A hinge joint allows backward and forward movement in only one direction, much like a door opening and closing.

Examples Knee joint Elbow joint

Gliding Joint

Flat surfaces move against each other allowing sliding or twisting without any circular movement

Fracture management stabilization devices

1. External fixation Casts

Plaster (fast, medium, slow-setting) Fiberglass Types

Shoulder spica Minerva jacket Body cast Short arm/leg Long arm/leg Hip spica Cylinder cast

Hip Stabilization

Goals of Casting/Splinting

Relieve pain Augment healing Stabilize fracture Prevent further injury

Splinting is better if practical because it is easier to manage swelling considering the entire limb is not isolated by a circumferential cast

Casting Considerations

Casts– Proper placement of cast brings patient safety

issues• Patient’s limb should be elevated• Webril should be placed so no wrinkles are in cotton to

cause pressure sores• As plaster or fiberglass is placed, assistant must not

make marks in plaster as it dries—these may cause pressure sores

• Reflective materials will reflect heat given off by casting material if fiberglass and may burn patient’s limb

• Tip of limb should be cleaned of all prepping solution so patient may be monitored for signs of circulatory disruption: increasing pain, pain that progresses into numbness, cyanotic skin, cold skin, poor capillary refill

Casting Differences

Plaster

webril first

wet casting with warm water before application

primarily used on children or where a lot of swelling is anticipated because can split if necessary (poor circulation due to swelling)

Fiberglass

webril first

can wet with warm or cold water

cannot split if needed/must be removed and reapplied

Combo Casting

“Orthoglass” Outer soft sleeve (sock-like on outside) Inside composed of moldable fiberglass Wet, apply, wrap with ace

Fixation options – cemented or non-cemented

Common diagnostics performed prior to surgery

1. Lab studies – blood cultures, urine samples, spinal fluid or synovial fluid tests

Biopsy, bone marrow Erythrocyte sedimentation rate (ESR) –

measures rate of RBC fall, since inflammations cause them to fall faster than normal

Serum alkaline phosphates (SAP) – check for increased levels of SAP, which indicated multiple kinds of bone disease

Diagnostics (continued)

2. Diagnostics Arthrocentesis - procedure of using a syringe to collect

synovial fluid from a joint capsule. It is also known as joint aspiration. Arthrocentesis is used in the diagnosis of gout, arthritis, and synovial infections.

Arthrography – injection of gas or contrast media for inspection of cartilage and ligaments surrounding joints

Arthroscopy Bone densitometers – measuring bone density Computerized tomography (CT) Magnetic resonance imaging (MRI) X-rays
