Bunionectomy

medically referred to as hallux valgus, is a bony exostosis located on the medial side of the first metatarsal head of the great toe causing a lateral deviation of the toe.

Various types of surgical procedures are used to treat the condition, such as the Aken, Chevron, McKeever, Keller, and McBride techniques

Meniscus

A joint in which the two bony surfaces are joined by fibrocartilage The knee joint is cushioned to withstand activities such as walking, jumping, and running by a pair of are thick, crescent-shaped pads of cartilage that rest on the upper articular surface of the tibia. Injuries, particularly athletic injuries, are common and result in various types of tears in the cartilage.

What does an MRI diagnosis for Ortho?

This is a noninvasive imaging technique that relies on the body’s responses to a strong magnetic field.

CT Scan

is an X-ray of an organ or body detailing that structure at various depths. Multiple radiographs are taken at multiple angles, and the computer reconstructs these images to represent a cross-section or “slice” of the structure.

Polymethyl methacrylate (PMMA)

also referred to as bone cement, is routinely used during total joint arthroplasty. Bone cement stabilizes and keeps the implants in the correct anatomical position. The cement fills the cavity and spaces of the bone to form a bond between the implant and bone.

Tourniquet Times

should not be applied for more than 1 hour on an upper extremity or for more than 1½ hours on the thigh. After 1 hour of pressure, the surgeon should be notified, and again every 15 minutes thereafter.

fracture table

commonly used for surgery on a hip fracture and for femoral nailing. must be well understood by the personnel using it in order for it to be properly set up. have several moving parts and can cause injury to the patient and OR personnel if not correctly handled. The patient can be placed in the supine or lateral position

lateral position

is frequently used for operations on the hip and shoulder. The vacuum beanbag is often used to stabilize the patient in the lateral position, eliminating the need for roll towels and tape over the hips. The beanbag can be contoured to the body shape of the patient by adjusting the beanbag while the air is suctioned out.

reamers

The canal is reamed with subsequent larger sizes of reamers until the opening in the canal corresponds to the diameter of the shaft of the prosthesis.

Immovable Joints

synarthroses, the bones are in close contact with each other and separated by a thin layer of cartilage. An example is the suture lines of the cranial bones.

Slightly Movable Joint

amphiarthrosis -Lying between the bones of the joint is a disk of fibrous cartilage that connects the bones. Examples of this type of joint include cartilage that connects the vertebrae and the disk of cartilage called the symphysis pubis that connects the pubic bones. This type of joint allows some movement due to the limited flexibility of the cartilage.

Freely Movable Joints

A diarthrosis. All diarthroses are also referred to as synovial joints because these joints all contain a synovial membrane that secretes synovial fluid. Diarthroses are further classified according to the movements they allow

Ball-and-Socket Joints

This type of joint allows for the widest range of motion (ROM). It consists of a bone with a ball-shaped head that articulates with the cup-shaped socket in another bone. Movement in all planes is possible, including rotational. Examples include the shoulder and hip joints.

Condyloid Joints

allows for movement in only one plane with some lateral movement. The joint is composed of a condyle of one bone fitting into the fossa of another bone. An example is the temporomandibular joint in which the condyle of the mandible fits into the fossa of the temporal bone.

Gliding Joints

allow side-to-side and twisting movements. The articulating surfaces of the bones in the gliding joint are either flat or slightly curved. An example is the carpals of the wrist joint.

Hinge Joints

The elbow . This type of joint allows movement in only one plane, much like the motion permitted by the hinge on a door. is formed by the convex surface of one bone fitting into the concave surface of the adjacent bone.

Pivot Joints

allow only a rotational movement around a central axis. The joint formed at the proximal end of the radius

Saddle Joints

allow movement in a variety of planes. The articulating surfaces of the bones have both concave and convex regions. The surface of one bone fits into the equivalent surface of the other bone. An example is the joint formed by the trapezium of the wrist with the metacarpal of the thumb.

When to use Nails

• The type of nail to be used depends on the type and location of the fracture, whether ipsilateral trochanteric or condylar fractures are present, and whether bone fragments are present.

Names and Types of Nails

flexible nails such as the Rush and Ender; interlocking nails such as the Trigen; retrograde interlocking intramedullary nails; and standard nails such as the AO (surgical procedure description is for AO titanium femoral nail system).

Plates

• Surgical repairs that have been used in the past but have fallen out of favor include external fixation and plates and screws. The complications associated with plates and screws include infections and broken or bent screws and plates, which have contributed to femoral refracture.

Patella

Sesamoid (round) bones are found within tendons. Another example is the two sesamoid bones found on the head of the metatarsal in the foot forming what is referred to as the “ball” of the foot.

long bones

include bones of the arm (humerus), legs (femur), hands, and feet (phalanges)

Short bones

are the bones of the wrists (carpals) and ankles (tarsals). As evidenced by the wrist and ankle bones, short bones usually occur in clusters and aid in the movement of an extremity.

Distraction

s a term used to describe bone fragments that are separated so that bone contact does not occur.

Avascular necrosis

occurs when the capillary network or collateral circulation cannot be reestablished following a traumatic injury or when the vascular system is disrupted by other means.

compound fracture

compromises the integrity of the skin and allows for the possible entry of microorganisms, which may cause infection of the bone and injury to surrounding soft tissues

Delayed union

is a term used to describe an increase in the healing time of fractures. The reasons for are pathological (e.g., osteoporosis), mechanical (e.g., distraction of the fracture site or inadequate immobilization), or traumatic, referring to the type of injury sustained (e.g., comminuted fractures).

Nonunion

is when the fractured bone ends do not unite.

Malunion

occurs when the fracture heals in a position that does not resemble the original anatomical form of the bone and alters the mechanical function of the bone.

Compartmental syndrome

is an increase in pressure within a closed space that usually occurs in the forearm and tibia.

Stages of Healing

Inflammation

begins at the time of injury and lasts approximately 2 days.

Stages of Healing

Cellular Proliferation

begins approximately on the second day following the traumatic event. Macrophages debride the area and allow for the formation of a fibrin mesh that seals the approximated edges of the fracture site. The fibrin mesh serves as the foundation for capillary and fibroblastic ingrowth. A soft tissue or periosteal callus is formed on the outer surface or cortex of the fractured bone by the collagen-producing fibroblasts and osteoblasts.

Stages of Healing

callus formation

stage lasts 3–4 weeks. The soft tissue growth continues and the bone fragments grow toward one another, bridging the gap. Osteoblasts form a matrix of collagen that invades the periosteal callus, bridging the fracture site and uniting the two ends of the bone. Fibrous tissue, cartilage, and immature bone stabilize the fracture site.

Stages of Healing

Ossification

begins 2 or 3 weeks following the injury and can last 3–4 months. The matrix of osteoblasts, now called the osteoid, calcifies, firmly uniting the bone. The bone is now able to accept mineral deposits.

Stages of Healing

Remodeling

is the maintenance state of normal bone. Following a fracture, any devitalized tissue is removed and the new bone is organized to provide maximum support and function.

Colles Fracture

1. a fracture of the lower end of the radius in the wrist with a characteristic backward displacement of the hand.
