INJURIES TO BONES, JOINTS, TENDONS AND LIGAMENTS
CLASSIFICATION OF INJURIES
INJURIES TO BONES AND JOINTS
1. FRACTURES - A break(s) in a bone
2. DISLOCATION - The head of a bone becomes displaced at a joint
3. STRAIN - Overstretching of a muscle or tendon
4. SPRAIN - Wrenching or tearing of a ligament at a joint
FRACTURES
There are three types of fractures: -
CLOSED OPEN COMPLICATED
CLOSED
Where the skin over the site of a fracture is not broken
OPEN
Where there is a wound leading down to a fracture
COMPLICATED
Where there is an associated injury to important structures (organs, blood vessels or nerves), or when the fracture is associated with a fracture, of when the bone is broken into several small pieces, or when the broken ends are impacted together.
TYPES OF FRACTURES
GREENSTICK - common in children
TRANSVERSE - Clean break usually by direct blow
OBLIQUE - Fracture line crosses the bone at oblique angle
COMMINUTED - Bone is fragmented into two or more pieces
And is a result of very powerful direct forces.
IMPACTED - Broken ends of bones are jammed together,
Impaction occurs from indirect force.
SPIRAL - Result from twisting injuries
CAUSES
DIRECT FORCE - Where the bone breaks at the point where the force is
Applied, for example from kick or blow.
INDIRECT FORCE - Where a bone breaks at some distance from the spot where
Force has been applied, e.g., collar bone is fractured
Although the force was applied to the hand during a fall.
MUSCULAR ACTION - Where there is a violent contraction of muscles
PATHOLOGICAL - Disease or degeneration of the bone tissue has weakened the
Bone to the extent that it collapses under stress.
INJURIES TO BONES, JOINTS, TENDONS AND LIGAMENTS
SIGNS AND SYMPTOMS
Pain at or near the site of injury, made worse by movement
Tenderness or pressure over affected part or on touch
Swelling as result of blood loss into tissue
Bruising or discolouration of the skin
Deformities such as the shortening of a limb, angulation or rotation of the limb
Irregularities lumps or depressions on the surface of the bone
Loss of function with the patient unable to move the affected part normally
Unnatural movement and loss of control
CREPITUS, a cracking sound or grating feeling may be felt or heard; never seek crepitus, it can be caused by improper handling where the two broken ends of bone are allowed to move together on each other.
MANGEMENT OF FRACTURES
If in doubt always assume a fracture
Treat a fracture before moving the patient unless conditions dictate
Administer entonox before starting immobilization
Support and immobilize the injured part, straight limbs if possible
Avoid direct pressure to the injury site, dress any wounds - open fractures
If it is not possible to apply a splint, place in comfortable position
Place the patient in a comfortable position, raise affected part if possible
Passing bandages under the natural hollows of the body, secure on opposite side
Of fracture.
Check for swelling, circulation or nerve impairment below the site of the injuy.
INJURIES TO BONES, JOINTS, TENDONS AND LIGAMENTS
DISLOCATIONS
A dislocation is a displacement of one or more bones at a joint. It may also be accompanied by a fracture.
CAUSES
Direct force as with a fracture
Indirect force, for example, during a fall where a person lands on a hand of an outstretched arm and dislocates the shoulder joint.
Pathological, where the ligaments containing the joint become weakened as a result of old age, disease, or previous injury.
SIGNS AND SYMPTOMS
As for a fracture, except where there is a fixation of a joint and therefore no movement. Often it is impossible to distinguish between a fracture and a dislocation if the injury is near a joint.
MANAGEMENT OF A DISLOCATION
· Management as for a fracture
· Not attempting to move or straighten the injury
· Immobilizing by the best means possible
· Improvising if necessary
STRAINS AND SPRAINS
STRAIN
Overstretching or tearing of a muscle and/or tendon. Caused when excessive tension or force is applied to a muscle, for example field sports or overstretching.
SPRAIN
Overstretching or tearing of a ligament at a joint. Caused when the joint moves beyond it’s normal range. For example, a sprained ankle may be caused by slipping off a kerb.
INJURIES TO BONES, JOINTS, TENDONS AND LIGAMENTS
STRAINS and SPRAINS (continued)
SIGNS AND SYMPTOMS
· Swelling, severe with sprain
· Severe cramp with a strain
· Bruising
· Pain which increases during movement
· Tenderness
MANAGEMENT OF SRAINS AND SPRAINS
· Resting and supporting the injured areas
· Providing plenty of soft padding
· Applying firm pressure to the site of the injury
· Apply cold compress to reduce swelling and reduce pain
· Administer entonox (if trained to do so).
