Flashcards in Forearm and Hand X Deck (31):
1

Lateral epicondyltis
**

tennis elbow - inflammation of tendon at lateral epicondyle
Results for overuse

2

Carpal Tunnel Syndrome
**

most common nerve entrapment
Median nerve trapped through bony carpal tunnel

3

Scaphoid Bone fractures
**

fractured frequently with fall onto outstretched hand. can go undiagnosed

4

Mallet finger
**

Overstretching or tearing of extensor tendon. finger wot straighten at tip

5

Trigger Finger
**

inflammation in flexor tendons or associated digital sheaths. sheath or tendon may thicken or nodules form = decreased ability of tendon to glide through sheath during finger movements.

6

Bicipital aponeurosis
**

covering for the brachial artery and median nerve

7

Contents of Cubital fossa (L->M)
**

tendon of biceps brachii, brachial artery, median nerve

8

Compartments of the Forearm

Anterior (Flexor)
Posterior (Extensor)
Lateral Intermuscular Septum
Interosseous Membrane (connect Radius and Ulna)

9

Anterior Forearm Compartment - Genral parts,Fxns

Superficial, Intermediate, Deep
Movements of the wrist joint
Flexion of the fingers and thumb
Pronation of the forearm

10

Anterior forearm - Superficial Muscles (L->M)

Pronator Teres
Flexor Capilaris Radialis
Palmaris Longus
Flexor Capilaris Ulnaris

11

Anterior Arm - Intermediate Muscles, importance

Flexor digitorum superficilias (two heads)
Median nerve (just deep)
ulnar artery (just deep)

12

Anterior Arm - Deep Muscles

Flexor digitorum porofundus
Flexor pollicis longus
Pronator Quadratus

13

Radial Artery - location

Superficially
Anterior lateral area of wrist
DOESNOT run with radial artery

14

Ulnar Artery

SUperficial
Anterior medial in wrist
Branches to ant and post Interosseous arteries that will be medial to wrist.

15

What doesnt pass through Carpal Tunnel?
**

ulnar nerve and artery, and palmar cutaneous branch of median nerve

16

Carpal tunnel components
**

Median nerve
tendons of FDS, FDP, FPL

17

Thenar Muscles - list, innervation

Abductor Pollis Brevis
Flexor Pollis Brevis
Opponens Pollicis
recurrent branch - median nerve

18

Hypothenar Muscles - list, innervation

Abductor digiti minimi
Flexor Digiti minimi brevis
Opponed digiti minimi
Deep branch -ulnar nerve

19

Adductor Pollicis - fxn, innervation

Thumb movement
deep branch ulnar nerve

20

Lubricales - List, fxn

1,2,3,4
Flex at MCP joint,
Promote extension at PIP and DIP joints

21

Boundaries of Cubital Fossa
**

Between bracioradialis and pronator teres
Floor - brachialis

22

Arterial Supply - Palm
**

Superfical Arch - ulnar and radial arteries

23

Sensory Innervation - palm
**

Median nerve to palm - superfical branch

24

Boundaries of snuffbox
***

(Lateral) Abductor Polliccis Longus/Extensor Pollicis Brevis
(Medial) Extensor Pollicis Longus
(Floor) Schaphoid and Trapezium
distal tendons of extensor carpi radialis longus and brevis
(Bottom) Extensor Retinaculum

25

Structures of snuffbox, clinical significance
***

Radial Artery
Scaphoid fracture = radial artery compressed
NO blood supply to bone = degeneration

26

significance of extensor hood
***

Tendons of ED and EPL pass to dorsal hand and expand over phalanges
Intrinsic have muscles insert to allow fine movements

27

Lateral Epicondylitis - affected muscles and movements
***

Inflammation and pain at tendons of Lateral epicondyle, Tennis elbow
Affects muscles of posterior arm - specifically extensor carpi radialis brevis
Affects wrist extension, gfip strength

28

Carpal Tunnel Syndrome - symptoms
***

Pain,weakness, numbeness in fingers, including thumb but not including palm or little finger due to compression of median nerve in carpal tunnel

29

Deep Branch of Radial Nerve could get entrapped under suppinator

KNOW

30

Ulnar Eminence

Hamate and Pisiform

31

Radial Eminence

Trapezium and Schappoind
