Tenosynovitis & desmitis

Question 1

what is a tendon?

Answer 1

muscle to bone attachment

Question 2

what is the tendon origin and insertion?

Answer 2

origin - muscle-tendon attachment
insertion - tendon-bone attachment (insert onto periosteum)

Question 3

Do tendons have sparse or vast tenocytes/fibroblassts?

Answer 3

sparse

Question 4

How are collagen fibrils oriented in relation to long-axis of limb? why?

Answer 4

parallel - important for elasticity and energy storage

Question 5

while _____ generate movement, ______ function to restrict movement between their two boney attachments

Answer 5

while tendons generate movement, ligaments function to restrict movement between their two boney attachments

Question 6

where is the vascular supply for tendons?

Answer 6

from muscle/bone at origin/insertion

Question 7

Compare tendon and ligaments - collagen, organization, elasticity

Answer 7

ligaments - less collagen, less highly organized, less elastic

Question 8

what are the two broad classifications of tendon injury?

Answer 8

internal causes (tendonitis)
external causes (blunt trauma, wounds)

Question 9

what are some of the internal causes of tendon injury?

Answer 9

biomechanical overload (strain)
hyperthermia
vascular

Question 10

Recent evidence suggests tendonitis is degenerative or inflammatory process?

Answer 10

degenerative

Question 11

which tendons are more commonly affected by tendonitis - flexors or non-weight bearing extensors?

Answer 11

flexors

Question 12

which is more commonly affected by tendonitis - SDFT or DDFT?

Answer 12

SDFT

Question 13

which tendon has the smallest cross-sectional area?

Answer 13

SDFT

Question 14

which tendon is the most external and is under the greatest strain/highest trauma risk?

Answer 14

SDFT

Question 15

which region is the SDFT least vascular?

Answer 15

mid-metacarpal
