AH 501: Chapter 10 - Tissue Response to Injury

•Limited capacity to heal

•Little or no direct blood supply

• Cartilage Healing

• Skeletal Muscle Healing

• Ligament Healing

• Nerve Healing

•Initial bleeding followed by proliferation of ground substance and fibroblast•Healing could last 6–8 weeks depending on muscle injured

• Ligament Healing

• Cartilage Healing

• Tendon Healing

• Skeletal Muscle Healing

•Cannot regenerate after injury

•For regeneration, optimal environment is necessary

•Rate of healing occurs at 3–4 mm per day

• Tendon Healing

• Nerve Healing

• Skeletal Muscle Healing

• Cartilage Healing

•Requires dense fibrous union of separated ends

Initially injured will adhere to surrounding tissues -- week 2

Gradual separation occurs -- week 3

Tensile strength not strong enough till 4-5 weeks

• Tendon Healing

• Cartilage Healing

• Ligament Healing

• Nerve Healing

•Certain organic disorders (blood conditions) may speed up the healing process

• True

• False

Therapeutic modalities that does the following: treatment of inflammation (ultrasound, electrical stimulation)

• Thermal agents

• Electrical modalities

With this technique the major aim is pain free movement full strength, power, and full extensibility of associated muscles.

–Uses the patient's own platelets to promote the natural healing of musculoskeletal conditions

• Prolotherapy

• Platelet-Rich Plasma Injections

• Microwave ultrasound

• Electrical Nerve stimulation

Acute fractures have ___ stages.

• 2

• 3

• 4

• 5

•develops during the first 48 hours

•Blood supply is disrupted by clotting vessels and cellular debris

• Ossification

• Cellular Proliferation

• Hematoma formation

• Remodeling
