WRIST BIOMECHANICS #WRIST COMPLEX | ULNAR VARIANCE (PART 1)

Detailed discussion on Wrist complex biomechanics. The wrist and hand complex are one of most complex joint in human body and even in it the wrist complex is most complex. Thats mainly because wrist joint serves a function of maintaing the length tension relationship of muscles of forearm. The Wrist complex is a compound joint made of the RADIOCARPAL JOINT AND MID CARPAL JOINT. There is detailed discussion on Radiocarpal joint structure the articular surface, the angulation of radius and the pecularities of distal segement of radiocarpal joint.Further Midcarpal joint structure, the articular surfaces and pecularities are also discussed.
Theres also discussion on the ULNAR VARIANCE #Postive ulnar varience #negative ulnar variance and neutral as well as brief idea on the #Kienbocks disease or #Avascular necrosis of lunate.
Finally the normal range of motion of wrist complex thats is the WRIST FLEXION, WRIST EXTENSION, RADIAL AND ULNAR DEVIATION is also included.

Queries solved;
1. What are joints in wrist complex
2. What is radiocarpal joint
3. Midcarpal joint
4. What is ulnar variance
5. What is ulnar negative variance
6. What is kienbocks disease
7. What is range of motion of wrist flexion
8. What is range of motion of wrist extension
9. What is range of motion of radial deviation
10. What is range of motion of ulnar deviation
