| What are the proximal carpals? | scaphoid, lunate, triquetrum, pisiform. |
| What are the distal carpals? | Hamate, capitate, trapezoid, trapezium. |
| If a hand position is PA, the marker should go on the ___ side. If a hand position is lateral, the marker should go on the __ side. | lateral anterior |
| Carpal Sulcus | the arch create by the natural curve of the wrist |
| what is the arch of the wrist called? | carpal sulcus |
| accessory bones located inferior to first metacarpal head Embedded within tendon Reduces strain during weight bearing | sesamoids |
| MCP joint | metacarpo-phalangeal joint |
| PIP joint | proximal interphalangeal joint |
| DIP | distal interphalangeal joint |
| CMC | carpo-metacarpal joint |
| intercarpal joints are classified as | as synovial, diarthrotic, gliding type |
| the trochlear notch is one the ___ bone. It is where the ___ meets this bone. | ulna; humerus. The swooping U of the ulna. |
| the most proximal aspect of the ulna is called the | olecranon process, the top of the U |
| The bottom of the U of the ulna is called the | coronoid process |
| A long pointy bone projection is called a | styloid process |
| the most distal point of the radius is the | radial styloid process |

| what scan uses a band aroudn the thumbs and looks for avulsion fractures/skiiers thumb | Folio Method |
| gaynor hart method looks for | carpal tunnel |
| most fractured carpal bone | scaphoid (proximal under the thumb) |
