25
What's subluxation?
Partial or incomplete dislocation Doesn't cause much disformity as a complete one
26
Mnemonic for managing a soft tissue injury
PRICE Protect Rest Ice Compress Elevate
27
What types of fractures are there?
Closed Open Intraarticular: Extends into the joint surface of a bone
28
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
29
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
30
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
31
Early complications of fractures
Shock Fat emolism Compartment syndrome VTE/ PE
32
Delayed complications of fracture
Delayed union, malunion, nonunion Avascular necrosis of bone Complex regional pain syndrome Heterotrophic ossification
33
What's compartment syndrome?
Increased pressure within a muscle compartment restricts blood flow , leading to tissue damage
34
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
35
Rehabilitation for humeral neck and shaft fractures
Slings and bracing Activity limitations until adequate period of immobilization
36
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
37
Rehab for Radial, ulnar, hand fractures
Early functional rehab exercises Active motion exercises of fingers and shoulder
38
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
39
Rehab for hip fractures
Surgery is done to reduce and fixate fracture Care is similar to someone undergoing surgery for hip
40
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
41
Assessment of patient with Brace, splint, or cast
Asses the 5 P's Monitor and treat pain
42
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
43
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
44
True or false: Traction must be continous to reduce and immobilize fractures?
TRUE
45
Nursing intervention for patient in skin traction
Monitor for skin breakdown, nerve damage, and circulatory impairment Inspect skin 3 times a day Palpate traction tapes for tenderness Asses capilarry fill and and temp of skin
46
Nursing intervention for patient in skeletal traction
Evaluate traction aparatus and patient positioning Maintain alignment of body Trapeze to help with movement Assess pressure points every 8 hours Regular shifting of positioning SPecial mattress Perform active foot exercises and leg exercises every hour Antiemolism stockings, compression devices Pin Care
47
Management of patients in traction
Monitor for Pneumonia, constipation, Anorexia, VTE Assist with self care
48
Assessment of patient with hip fracture
Vitals Respiratory function Bowel function
49
Assessment of patient with an amputation
Neurovascular assessment Coping Signs of infection
50
What is osteoarthritis?
Noninflammatory degenerative disorder of the joints Primary: No prior event or disease related to OA or secondary : resulting from other things
51
Risk factors for osteoarthritis
Older age Female Sports and occupation Obesity is most modifiable
52
Manifestations of osteoarthritis
Pain and stiffness Relieved with rest Morning stiffness Mostly in weight bearing joints
53
What are some ways we can prevent osteoperosis?
Balanced diet with vitamin C and D Regular weight bearing exercises Weight training to stimulates bone density
54
Pharmacological therapy for osteoperosis
Calcium and Vitamin D Bisphonates Calcitonin Estrogen antagonists/ agonists Parathyroid hormone
55
Nursing interventions for a patient with spontaneous vertebral fracture related to osteoperosis
Relieving pain Improving bowel movements: high fiber diet, increased fluids, stool softeners Preventing injury
56
What's osteomalacia?
Metabolic bone disease characterized by inadequate bone mineralization Can be from deficiency of vitamin D Causes: GI disorders, renal insufficiency, hyperparathyroidism, dietary insufficiency
57
Management of osteomalacia

Skeletal deformities Pain and tenderness and warmth over bones Most patients don't have symptoms Pharmacological management: NSAIDS, antineoplastic therapy, calcitonin, biphosphanates, pilcamycin
60
What is osteomyelitis?
Infection of bone Occurs because of: Extension of soft tissue infection, direct bone contamination, blood born spread from another site infectinon Causative: MRSA, E. Coli
61
Assessment of patient with ostemyelitis
Signs and symptoms of infection With chronic, fever may be low grade and occur in afternoon or evening Signs and syptoms of adverse reactions and anitbiotic therapy
