Manifestations fracture include

Question 128

1. Fracture hematoma 2. Granulation tissue 3. Callus formation 4.Ossification 5.Consolidation 6. Remodeling

Answer 128

Bone goes through a complex multistage healing process (union) that occurs in 6 stages:

Question 129

When a fracture occurs, bleeding creates a hematoma that surrounds the ends of the bone fragments. The hematoma is composed of extravasated blood that changes from a liquid to a semisolid clot in the first 72 hours after injury

Answer 129

Fracture hematoma: (1st step in healing fracture)

Question 130

During this stage, active phagocytosis absorbs the products of local necrosis. The hematoma converts to granulation tissue. Granulation tissue (consisting of new blood vessels, fibroblasts, and osteoblasts) forms the basis for new bone substance (osteoid) during days 3 to 14 after injury.

Answer 130

Granulation tissue:(2nd step in healing fracture)

Question 131

As minerals (calcium, phosphorus, and magnesium) and new bone matrix are deposited in the osteoid, an unorganized network of bone is formed and woven about the fracture parts. Callus is primarily composed of cartilage, osteoblasts, calcium, and phosphorus. It usually appears by the end of the second week after injury. An x-ray can show evidence of callus formation.

Answer 131

Callus formation ( 3rd step in healing fracture)

Question 132

Ossification of the callus occurs from 3 weeks to 6 months after the fracture and continues until the fracture has healed. Callus ossification is sufficient to prevent movement at the fracture site when the bones are gently stressed. However, the fracture is still evident on x-ray. During this stage of clinical union, the patient may be allowed limited mobility, or the cast may be removed.

Answer 132

Ossification ( 4th step in healing fracture)

Question 133

As callus continues to develop, the distance between bone fragments decreases and eventually closes. Ossification continues and can be equated with radiologic union, which occurs when an x-ray shows complete bony union. This phase can occur up to 1 year after injury.

Answer 133

Consolidation (5th step in healing fracture)

Question 134

Excess bone tissue is resorbed in the last stage of bone healing, and union is complete. Gradual return of the injured bone to its preinjury structural strength and shape occurs. Bone remodels in response to physical loading stress (Wolff’s law). Initially, stress is provided through exercise. Weight bearing is gradually introduced. New bone is deposited in sites subjected to stress and resorbed at areas of little stress.

Answer 134

Remodeling (6th step in healing fracture)

Question 135

Question 149

inadequate immobilization, excessive movement of fracture fragments, infection, poor nutrition, and systemic disease (e.g., diabetes)

Answer 149

Ossification may be slowed or even stopped by

Question 150

Answer 188

To apply a cast on an extremity, first

Question 189

immerse it in warm water and then wrap and mold it around the affected part. The number of layers of plaster bandage and the technique of application determine the strength of the cast. The plaster sets within 15 minutes, so the patient may move around without difficulty. However, it is not strong enough for weight bearing until about 36 to 72 hours after application.

Answer 189

If using plaster of Paris (applying cast)

Question 190

submersion in cool or tepid water. Then they are molded to fit the torso or extremity.

Answer 190

Casts made of fiberglass or other synthetic materials (thermolabile plastic, thermoplastic resins, polyurethane) are activated by

Question 191

Leave a fresh plaster cast uncovered to allow air circulation. Covering the cast allows heat to build up in the cast. This may cause a burn and delay drying. Avoid direct pressure on the cast during the drying period. Handle the cast gently with an open palm to avoid denting the cast. Once the cast is thoroughly dry, the rough edges may be petaled to minimize skin irritation. Petaling also prevents plaster of Paris debris from falling into the cast and causing irritation or pressure necrosis. Place several strips (petals) of tape over the rough areas to ensure a smooth cast edge.
