Eval & Diagnosis Flashcards
Forearm Extensor muscles (posterolateral)
- Extensor carpi radialis longus
- Extensor carpi radialis brevis
- Extensor carpi ulnaris
- Brachioradialis
- Extensor pollicis longus
- Extensor pollicis brevis
- Adductor pollicis longus
- Extensor indicus supinator
Forearm Flexor Muscles
- Flexor carpi radialis
- Flexor carpi ulnaris
- Palmaris longus
- Flexor digitorum superficialis
- Flexor digitorum profundus
- Flexor pollicis longus
- Pronator quadratus
- Pronator teres
Colles’ fracture
- Lower end of radius or ulna
- FOOSA -hyperextention
- Out for 1-2 months
Silver Fork Deformity
Fwd displacement of the radius that causes a visible deformity to the wrist
Bishop’s or Benediction deformity
- Results from injury to ulnar nerve
* Flexion of pinky and ring finger
Claw Hand
- Results from compression of he median and ulnar nerve
* Flexion of all fingers and thumb
Drop Wrist
- Results from palsy of the radial nerve
* Wrist flexion
Ape Hand
Results from palsy of the median nerve
*Thumb is pulled into extension and fingers 2-5 into flexion
What runs through the carpal tunnel?
- Flexor digitorum profundus (4 tendons)
- Flexor digitorum superficialis (4 tendons)
- Flexor pollicis longus (1 tendon)
- Median nerve
De Quervain’s Disease (Hoffman’s Disease)
- Stenosing tenosynovitis in the thumb
* Effects the extensor pollicis brevis & abductor pollicis longus
Bowler’s Thumb
Perineural fibrosis of the subcutaneous ulnar digital nerve of the thumb
Trigger Finger/Thumb
Stenosing tenosynovitis commonly occurring in a flexor tendon
Mallet Finger
- Avulsion of an extensor tendon in the finger from the insertion.
- PIP into 30° of flexion
- splinted in extensio for 6-8 weeks
Boutonniere (Buttonhole) Deformity
- Rupture of the extensor tendon dorsal to the middle phalanx
- DIP joint into extension and PIP into flexion
- Splinting for 5-8 weeks
Jersey Finger
- Rupture of the flexor digitorum profundus tendon from the insertion of the distal phalanx
- DIP cannot be flexed
Dupuytren’s Contracture
- Nodules develop in the palmar aponeruosis
* Limit extension and eventually cause felxion deformity
Gamekeepers Thumb
*Sprain of the UCL of the MCP in the thumb
*Forceful abduction and possible hyperextension of the thumb
*
Swan Neck (Pseudoboutonniere) Deformity
- Injury to the proximal volar plate of the PIP
* Hyperextenstion of the PIP and flexion of the DIP
Bennett’s Fracture
- Fx in at the CMC of the thumb
* From axial and abduction forces
Degrees of ROM in the Shoulder
- Flexion: 180°
- Extension: 50°
- Abduction: 180°
- Adduction: 40°
- Internal Rotation: 90°
- External Rotation: 90°
