What types of fractures are there?
Closed
Open
Intraarticular: Extends into the joint surface of a bone
Grades of open fractures
1: 1 cm long clean wound
2: Larger wound without extensive damage
3: Highly contaminated extensive soft tissue injury that may need to be amputated
Emergency management of a fracture
Immobilize body part
SPlintint: Joints distal and proximal to the suspected fracture must be supported and immobilized
Asses neurovascular status before and after splinting
Open fracture: Cover with sterile dressing
Do not attempt to reduce fracture
Medical management of fracture
Fracture reduction: Restoration of the fracture fragments to anatomic alignment and positioning
Closed: Uses manipulation and manual traction , traction may be used
Open: Internal fixaiton devices hold phone fragment in position (pins, wires, screws, plates)
Immobilization: Casts, splints, internal fixations
Early complications of fractures
Shock
Fat emolism
Compartment syndrome
VTE/ PE
Delayed complications of fracture
Delayed union, malunion, nonunion
Avascular necrosis of bone
Complex regional pain syndrome
Heterotrophic ossification
What’s compartment syndrome?
Increased pressure within a muscle compartment restricts blood flow , leading to tissue damage
Rehabilitation of clavicle fractures
Use of clavicular strap or sling
Excersises for wrist, elbow, and fingers asap
Do not elevate arm above shoulder for about 6 weeks
Rehabilitation for humeral neck and shaft fractures
Slings and bracing
Activity limitations until adequate period of immobilization
Rehab for elbow fractures
Monitor regularly for neurovascular compromise and signs of compartment syndrome
Potential for VOlkkman contracture
Active exercise and ROM are encouraged to prevent limitation of joint movement after immobilization and healing (4-6 weeks for nondisplaced, casted) and 1 week for internal fixation
Rehab for Radial, ulnar, hand fractures
Early functional rehab exercises
Active motion exercises of fingers and shoulder
Rehab for pelvic fractures
Managment depends on type and extent of fracture and associated injuries
Stable fractures are treated with a few days of bed rest and symptom management
Early mobilization reduces problems related to immobility
Rehab for hip fractures
Surgery is done to reduce and fixate fracture
Care is similar to someone undergoing surgery for hip
Rehab for femoral shaft fracture
Lower leg, foot, and hip exercises to preserve muscle function and improve circulation
Early ambulation stimulates healing
Physical therapy, ambulation, and weight bearing are prescribed
Active and passive knee exercises are begun as soon as possible to prevent restriction of knee movement
Assessment of patient with Brace, splint, or cast
Asses the 5 P’s
Monitor and treat pain
Problems that can happen with brace, splint, or cast
Acute compartment syndrome: Ischemia and irreversible damage can occur within hours ; notify physician
Pressure injuries: Patient reports a “hot spot” and tightness
Disuse syndrome: Muscle atrophy and loss of strenght
What is traction in relation to the muscle shi?
Pulling force to a part of the body
Reduces spasms
Aligns fractures
Reduces deformity
Used as a short term intervention
Traction needs to be applied in 2 directions ; whenever theres a force applied a counterforce must be applied
2 types: Skin and Skeletal
True or false: Traction must be continous to reduce and immobilize fractures?
TRUE
