Hand Flashcards
In which conditions is pollicization indicated?
Blauth 3b and above or traumatic injuries with unstable CMC.
What does the index MP become after pollicization?
Thumb CMC.
What does the index PIP become after pollicization?
Thumb MCP.
What does the index DIP become after pollicization?
Thumb IP.
What function does the extensor digitorum communis serve after pollicization?
Function of the abductor pollicis longus.
What structure attaches to the radial lateral band to perform the function of the abductor pollicis brevis?
Dorsal interosseous.
Fill in the blank: Pollicization is indicated in traumatic injuries where the CMC is not _______.
[stable].
True or False: The flexor digitorum profundus serves the function of the flexor pollicis longus after pollicization.
True.
What are the three joints that need to be replaced during pollicization?
- CMC
- MCP
- IP
What is the acronym LOAF used to describe?
Intrinsic muscles innervated by the median nerve
LOAF stands for: Lumbricals to index and long, Opponens pollicis, Abductor pollicis brevis, Flexor pollicis brevis (superficial head).
List the sites of compression for the ulnar nerve.
- Between the heads of the flexor carpi ulnaris
- Arcade of Struthers
- Osborne’s ligament
- Anconeus epitrochlearis
- Guyon’s canal
These sites are common areas where the ulnar nerve can become compressed and lead to symptoms.
What are the common sites of compression for the median nerve?
- Supracondylar process
- Ligament of Struthers
- Lacertus fibrosis
- Between the heads of the pronator teres
- Leading edge of the FDS aponeurosis
- Carpal tunnel
These are common anatomical locations where median nerve compression occurs.
True or False: The ligament of Struthers is a canal from the medial triceps to the intermuscular septum.
False
The ligament of Struthers is a fibrous band, not a canal, and it connects the supracondylar process to the medial epicondyle.
