The human body has a strong skeleton made up of many bones which support the muscles and tissues of the body. And bones that can be seen and felt beneath the skin provide landmarks for locating part of the body. Some of the skeleton with their names in the areas of the body are shown in the illustration.

Cracked Bone Chipped Bone Broken Bone Fractures and Dislocations Fracture Dislocation

- Open - Bone protrudes through skin or wound leading to site of the fracture. - Closed - Bone remains within the skin. No wound leading to site of the fracture. Fractures and Dislocations Complicated - May involve body organs and tissue.

Fractures and Dislocations A fracture means a broken Bone. They can be caused by: Direct Force Indirect Force Abnormal Muscular Contraction

Signs –Swelling –Discolouration –Deformity –Shortening –Abnormal mobility Symptoms –Pain –Loss of power –Tenderness –Crepitus Fractures and Dislocations

Splints

Dislocations A dislocation occurs when extreme force is put on a ligament, allowing the ends of two connected bones to separate. Ligaments are flexible bands of fibrous tissue that connect various bones and cartilage. Ligaments also bind the bones in a joint together. Stress on joint ligaments can lead to dislocation of the joint. The hip and shoulder joints, for example, are called "ball and socket" joints. Extreme force on the ligaments in these joints can cause the head of the bone (ball) to partially or completely come out of the socket. What is a dislocation?

Dislocations

Severe pain, unable to move and appears deformed Prevent movement at the site. Place in a comfortable position. Prevent Pain. Apply Ice. Prevent Bleeding. Seek medical aid. Do Not replace into position. Dislocations Signs and Symptoms General Management

Sprains and Strains Sprain The stretching and tearing of ligaments and other soft tissue structures at a joint Strain The stretching and tearing of muscles and tendons

How does Ice work? An injury damages blood vessels, causing bleeding in the injured area. Injury irritates nerve endings causing pain. Applying Ice: –constricts blood vessels, slowing down bleeding that causes the injury to swell. Cold deadens nerve endings and relieves pain.

Types of Skull Fracture Head Injuries

Mechanism of Head Injuries Direction of Impact

A temporary impairment of brain function, usually without permanent damage to the brain Concussion - Brain Shaking -

Concussion Signs & Symptoms Brief or extended periods of unconsciousness Double vision Confusion Loss of short memory (what actually happened). Headache Nausea and vomiting Numbness (tingling and weakness in arms and legs) Lack of co-ordination (stumbling).

Cerebral Compression This may be caused by trauma to the head, or by a blood clot formed within the skull Cerebral compression is a condition which occurs when pressure within the brain increases

Cerebral Compression Signs and Symptoms Diminishing conscious state. Noisy or irregular breathing. Slow but full and bounding pulse. Weakness in one side of the body. Unequal pupils. Flushed face. Fever.

Spinal Injuries May be caused by Vehicle Accidents. Heavy fall onto buttocks. Surfing accidents. Diving into shallow water. Skiing accidents. Incorrect lifting.

Spinal Injuries Symptoms and Signs Severe back Pain. Lower limb numbness. Loss of power in limbs. Loss of sensation.

Care for Head & Spinal Injuries Spinal Injuries Maintain an open airway. Minimise movement of Head & Spine. Monitor A.B.C. Control any Bleeding. Maintain Body Temperature. If unconscious, carefully place in lateral position.

Eye Injuries Injuries to the eye can involve the bone and soft tissue surrounding the eye, or the eyeball itself. Blunt objects such as a cricket bat or a golf ball may injure the eye area or a smaller object mat penetrate the eyeball. Eye injuries can also be caused by heat, smoke, welding flash or chemicals which burn. Any eye injury should be treated as serious. Injuries which penetrate the eyeball or cause the eyeball to be removed from the socket are very serious and can cause blindness.

Types of Eye Injuries

Foreign Bodies Superficial Wash thoroughly (if unsuccessful, Pad both eyes. Seek medical aid. Embedded / Penetrating Lie flat. Pad both eyes. Reassure the person. Seek medical aid.

Eye Injuries Symptoms and Signs of Eye Injuries PAIN REDNESS WATERING May indicate surface or internal bleeding. BLEEDING IMPARED VISION May indicate internal injury. REMEMBER: History may be more relevant than symptoms and signs

Eye Injuries Irrigating the Eye Hold eyelids apart. Gently Flush with water for 20 Minutes. Seek Medical Aid.

Eye Injuries Care for Eye Injuries Padding both Eyes Paper Cup used as protection for an eye injury. This method is used for penetrating wounds.

Eye Injuries REMEMBER Never Touch the Window of the Eye

Slings Time for a little more practice.
