Mechanical Immobilization Mechanical Immobilization• Introduction
Mechanical immobilizations are used for clients with impaired mobility as a result from trauma or debilitating condition.
Orthoses – orthopedic devices that support or align body parts and prevent or correct deformities. Examples of orthoses are splints, immobilizers, and braces.
Purposes of Mechanical Immobilization
Purposes of Mechanical Immobilization
• Mechanical immobilization is usually used to treat musculoskeletal trauma in order to:
Reduce pain and muscle spasms; support and align skeletal injuries
Restrict movement and maintain functional position while injuries heal; allow activity while restricting movement of injured area
Prevents structural damage and Deformity
Mechanical Immobilizing DevicesMechanical Immobilizing Devices
• Splints- immobilizes and protects an injured body parts. Used before or instead of a cast
• Splint types include:
– Emergency
– Commercial
Inflatable
Traction

Inflatable SplintsInflatable Splints
Traction SplintsTraction Splints
Other SplintsOther Splints• Commercial splints
– More effective than improvised splints
– Include:
o Immobilizers , Inflatable splints
o Molded splints, traction splints
o Cervical collars
Mechanical Immobilizers Mechanical Immobilizers
Inflatable Splints or pneumatic splint, becomes rigid when filled with air.
• They control bleeding and swelling
Traction Splint are metal devices that immobilize and pull on contracted muscles. An example Thomas splint (fig 25-3)
Immobilizers made from cloth and foam and held in place by adjustable hook and loop tape. Such as velcro strap ( fig 25-4).
Mechanical Immobilizers Cont’d Mechanical Immobilizers Cont’dMolded splints used for chronic injuries or diseases.
They provide support and limit movement to prevent further injury and pain, and also maintain the body part in a functional position, preventing contractures.
Cervical Collars is a foam or rigid splint around
the neck, treatment for neck sprains or strains.
Worn continuously, , removed for gentle ROM
exercises.
Mechanical Immobilizing Devices Cont’d
Mechanical Immobilizing Devices Cont’d
• Slings- a cloth device that elevates, cradles and support parts of the body, applied to arms, legs
• Braces- custom made devices designed to support weakened muscles.
• Types of braces
– Prophylactic- reduces severity of joint injury. Rehabilitative protects operative joint during movement. Functional provides stability

CastsCasts
• Casts are rigid molds used to immobilize injured body structures after alignment. Applied to fractured bones. POP is used (Plaster of Paris)
– Types of casts
o Cylinder (may be bi-valved)
o Body (may be bi-valved)
o Spica
Casts Cont’d Casts Cont’d
• Cylinder Casts- covers the arms and legs, but leaves the toes or fingers exposed.
• Body Cast- encircles the trunk of the body, from the nipple line to the hips
• Bi-Valve Cast- cast is cut into two pieces lengthwise. Done when there is swelling, interfering with circulation, there is pain or the client is being weaned from the cast
• Spica Cast- encircles one or both the arms and legs and the chest or trunk. Upper body is called shoulder spica, lower body is called hip spica.

Cast MaterialsCast Materials
Cast ApplicationCast Application
This procedure requires more than one person
Nurse prepares the client, assembles the client, assembles cast supplies, making appropriate assessments to prevent complications
(Refer to Skill 25-2 in the textbook.( Page 551-552)
Basic Casts Care (cont’d)Basic Casts Care (cont’d)• Cast Removal
• Cast are removed when they need to be changed and reapplied, or when the injury has healed sufficiently that the cast is no longer necessary. Casts are removed
– Electric cast cutter may frighten clients due to noise
– Skin care important after cast removal

Basic Cast CareBasic Cast Care
TractionTraction
• Traction: pulling effect exerted on a part of the skeletal system. It is a treatment measure for musculoskeletal trauma and disorders
• It is Used
– Reduce muscle spasms; Realign bones
– Relieve pain; Prevent deformities
– Traction is from the clients own body wt.
Traction (cont’d)Traction (cont’d)• Traction types include:
– Manual-pulling on the body using muscular strength, to realign broken bone.(f-25-14
– Skin- pulling effect on the skeletal system by applying devices to the skin
– Skeletal-means pull exerted directly on the skeletal system by attaching wires,pins, or tongs into a bone
Examples of tractions Examples of tractions
Skin traction, Pelvic belt& cervical Halter
Mauual traction
Traction (cont’d)Traction (cont’d)
• Traction care
– External fixator-
– Pin site care to prevent infection
• Effective traction depends on consistent application of traction principles

Principles for Maintaining Effective Traction
Principles for Maintaining Effective Traction
External FixatorsExternal Fixators
• Metal devices surgically inserted into or through one or more broken bones to stabilize during healing
Nursing Implications Nursing Implications
• Nursing diagnoses include:
– Acute pain; impaired physical mobility or bed mobility
– Risk for disuse syndrome, peripheral neurovascular dysfunction, impaired skin integrity, ineffective tissue perfusion
– Self-care deficit: bathing/hygiene
Risk for Peripheral Neurovascular Dysfunction
Risk for Peripheral Neurovascular Dysfunction
General Gerontologic ConsiderationsGeneral Gerontologic Considerations
• Common causes of hip fractures in older adults
• Longer healing time due to brittle bones
• Stiffer joints due to decreased synovial joint fluid
General Gerontologic Considerations (cont’d)
General Gerontologic Considerations (cont’d)
• Due to diminished tactile sensation, older adults may be unaware of skin pressure from cast, brace, etc.
• Remove indwelling catheters as soon as possible after surgery to prevent incontinence and urinary tract infections
• Cautious use of narcotics for pain management to avoid adverse effects
General Gerontologic Considerations (cont’d)
General Gerontologic Considerations (cont’d)
• Implement measures to increase bone density in older adults to prevent fractures:
– Drink liquid supplements high in nutrients; include protein, calcium, and zinc in diet to promote healing in a musculoskeletal injury
– Encourage sun exposure for vitamin D absorption
General Gerontologic Considerations (cont’d)
General Gerontologic Considerations (cont’d)
• Post-orthopedic surgery interventions for older adults
– Bladder training schedules to maintain or regain continence
– Appropriate rolling technique when using fracture-style bedpan
General Gerontologic Considerations (cont’d)
General Gerontologic Considerations (cont’d)
• Nonsurgical treatment of fractures of the upper extremities includes:
– Immobilization
– Occupational and physical therapy to regain function and range of motion
