Chapter 63: Med Surg Flashcards
sprain
injury to a ligamentous structure surrounding a joint, usually caused by wrenching or twisting motion
first degree sprain
mild; involves tears in only a few fibers resulting in mild tenderness and minimal swelling, self-limiting with full fx returning within 3-6 weeks
second degree sprain
moderate; involves partial disruption of the involved tissue with more swelling and tenderness
third degree sprain
complete tearing of a ligament in association with moderate to severe swelling, a gap in the muscle may be apparent, may require surgical repair if it involves the fascia or tendons
strain
excessive stretching of a muscle and its fascial sheath usually involving the tendon, mostly occur in large muscle groups
why does edema develop in an injured area?
tiny hemorrhages within the disrupted tissues occur along with the local inflammatory response
acute intervention of strains and sprains
stopping the activity and limiting movement, applying ice, compressing, elevating, and providing analgesia
compression
limits swelling, wrapped starting distally and progressing proximally to encourage fluid return, bandage left in place for 30 minutes and removed for 15 minutes
dislocation
severe injury of the ligamentous structures that surround joint evidence by obvious deformity and local pain, tenderness, loss of fx of injured part, and swelling
tx for dislocation
prompt attention! must be realigned and immobilized, nurses need to reduce pain and protect injury
subluxation
partial or incomplete displacement of the joint surface, less severe than dislocation, may require less healing time
repetitive strain injury
cumulative traumatic disorder resulting from repetitive movements, awkward postures, or sustained force causing tiny tears that become inflammed
s/s of repetitive strain injury
pain, weakness, numbness, impairment of motor fx
tx of repetitive strain injury
precipitating activity, modification of activity, pain management with heat/cold, rest, to type: keep the hips and knees flexed to 90 degrees and feet flat with the wrists kept straight
carpal tunnel syndrome
caused by compression of the median nerve caused by pressure from trauma or edema caused by inflammation of tendon
s/s of carpal tunnel
weakness especially in thumb, burning pain, tingling, numbness, and + phalen’s test
predisposed to carpal tunnel
diabetes, hypothyroidism, women
tinel’s sign
tapping over the median nerve as it passes through the carpal tunnel in the wrist and positive response is sensation of tingling
phalen’s sign
allow wrists to fall freely into maximum flexion and maintain position for longer than 60 seconds, positive sign is sense of tingling over median nerve
tx of carpal tunnel
in acute cases, stop the aggravating motion and let wrist rest with wrist splint, injection of corticosteroid directly into carpal tunnel may relieve, avoid extreme temps, carpal tunnel release
release surgery
indicated if symptoms persistent for more than 6 months, open release enlarges carpal tunnel and endoscopic is faster and causes less pain
rotator cuff injury
occurs gradually from aging, repetitive stress, or injury from falling, can tear as sudden force of adduction occurs when limb is in abduction, confirmed with MRI
s/s rotator cuff injury
shoulder weakness, severe pain when the arm is abducted 60-120 degrees, decreased ROM, drop arm test
drop arm test
arm falls suddenly after is has been abducted 90 degrees is a sign of rotator cuff injury
tx rotator cuff injury
rest, ice, heat, NSAIDs, corticosteroid injections to joint, physical therapy, surgery indicated when complete tear or no improvement with conservative therapy (arthroscope surgery)
meniscus injury
associated with ligament sprains that commonly occur in athletes (basketball, football, rugby, soccer, hockey) exhibited by rotational stress when the knee is in varying degrees of flexion and foot is planted; MRI diagnose
s/s of meniscus injury
pain with flexion, internal rotation, and knee extension, no significant edema, localized tenderness, knee clicks or pops, quadricep atrophy is injury has not been tx
tx meniscus injury
ice, immobilization, weight bearing as tolerated, knee brace, physical therapy, surgery may be indicated and done with arthroscopy
anterior cruciate ligament (ACL) injury
usually occurs from noncontact when the athlete pivots, lands from a jump, or slows down when running, x rays and MRI diagnostic
lachman’s test
flex the knee 15-30 degrees and pull tibia forward while femur is stabilized, considered positive for ACL injury if there is forward motion of the tibia with the feeling of a soft or indistinct endpoint
tx for ACL injury
if intact: rest, ice, NSAIDs, elevation, ambulation, knee brace; if severe ligament and meniscus injury: surgery, recovery within 6-8 months
bursitis
results from repeated or excessive trauma or friction in bursae (synovial fluid)
s/s bursitis
warmth, pain, swelling, limited ROM
