Answers.
Hand Bone correct answers Some (Scaphoid) Proximal
Lovers (Lunate) Proximal
Try (Triquetrum) Proximal
Position (Pisiform) Proximal
That (Trapezium) Distal
They (Tubercles) Distal
Can't (Capitate) Distal
Handle (Hamate) Distal

Radiocarpal impingement correct answers B/w lateral side of carpus and styloid process of the
radius
- Extension and radial deviation is the most likely position where this occurs

Radius Features correct answers Ulnar tilt: 25° (ulnar deviation > radial deviation)
Palmer tilt: 10° (wrist flexion > extension)

Radiocarpal correct answers Compressive F across joint: (Need to know)
- 20% THROUGH DISC (proximal w/ radius)
- 80% THROUGH SCAPHOID/ LUNATE (distal)

Wrist Joints correct answers NOT a lot of motion: based on the ligaments
- More motion at medial vs. lateral mid carpal joints
- Intercarpal: Limited motion, small gliding and rotary motion, ligaments stability and support
(majority stabilized like this)

Wrist Ligaments correct answers Primary Function: MAINTAIN INTERCARPAL
ALIGNMENT
- Transfer F from wrist to carpus

Triangular Fibrocartilage Complex (TFCC) correct answers - Ligaments, tendon, meniscus, and
disc to help assist w/ motion
- Commonly injured b/s lots of passive static stabilizers and takes a long time to heal b/c of
avascularization (80%)

Kinematics of Wrist Motion correct answers 2 DOF (Axis goes through capitate)
1. Flexion/ Extension
2. Ulnar/ Radial Deviation

Wrist Axis of Rotation correct answers Axis is on central column (radius, lunate, capitate, 3rd
MC)
- Motion= radiocarpal + mid carpal joints: Yields a sig. total range of motion by requiring only
mod amts. of rotation @ ind. jts.

, Wrist Extension correct answers STABLE CLOSED PACK
- B/c passive insufficiency @ the flexors
- Elongates palmer radoiocarpal ligaments (all in full tensile load)

Wrist Flexion & Extension correct answers EXTENSION:
Rolling dorsal
- Palmar ligament getting taut
Sliding palmar
- Dorsal ligament on slack
FLEXION:
Rolling anteriorly/ palmer
- Palmer ligament slack
Sliding palmar/ dorsal
- Dorsal ligament on slack

Ulnar/ Redial Deviation correct answers No SLACK in INTRINSIC CARPAL LIG. (taut)
ULNAR Deviation
- Carpal roll medially (to ulna)
- Slide toward radius
RADIAL Deviation
- Carpal roll laterally (to radius)
- Slide toward ulna

Double V Concept correct answers DRIVEN by muscle: b/w palmer inter carpal ligaments
- Roll toward= slack
- Glide away= taut
- When deviating: Always proximal ligament getting slack while distal getting taut and vice
versa

Carpal Instability correct answers 1. Rotational Collapse: like train care de- railing, named by the
direction of the lunate's distal articular surface faces (how the concave side faces)
- VISI
- DISI
2. Ulnar Translocation

DISI (Dorsal [posterior] Intercalcated Segment Instability) correct answers Rupture on palmar
ligament
- Distal side of lunate is facing the dorsal side

VISI (Volar [anterior] Intercalcated Segment Instability) correct answers Rupture on dorsal
ligament
- Distal side of lunate facing the volar (palmer) side

Scaphoid Fracture correct answers - Most fractured carpal of the wrist
- Can lead to avascular necrosis (bone death)
