Bony Anatomy[edit | edit source]
The hand and wrist have a total of 27 bones arranged to roll, spin and slide[1]; allowing the hand to explore and control the environment and objects.
The carpus is formed from eight small bones collectively referred to as the carpal bones. The carpal bones are bound in two groups of four bones:
- the pisiform, triquetrum, lunate and scaphoid on the upper end of the wrist
- the hamate, capitate, trapezoid and trapezium on the lower side of the hand.
Other bones of the hand are:
- the metacarpals – the five bones that comprise the middle part of the hand
- the phalanges (singular phalanx) – the 14 narrow bones that make up the fingers of each hand. Each finger has three phalanges (the distal, middle, and proximal); the thumb has two[2].
The hand is divided into three regions[3]
- Proximal region of the hand is the carpus (wrist)
- The middle region the metacarpus (palm)
- The distal region the phalanges (fingers)
The forearm consists of the radius and ulna and a complex and interrelated set of joints
- distal radioulnar joint
- proximal radioulnar joint
- soft tissue stabilizers between the 3 bones
- triangular fibrocartilage complex at the wrist (The crucial stabiliser)
- annular ligament at the elbow
- interosseous membrane in the forearm (load transmission from radius to ulna[4])
- palmar and dorsal radioulnar ligaments
This arrangement guarantees stability of the joint throughout pronation and supination[5]
Disruptions in any of these structures may lead to forearm instability[6].

Tools used to measure range of motion in the wrist and hand[edit | edit source]
Goniometer | Inclinometer | Cellphone Inclinometer[11] | |
---|---|---|---|
Pros | Compact, easy to use and portable | Accurate and measures multiple planes | Accurate, measures multiple planes, free downloadable appconvenient |
Limitations | Only one plane of movement | Bulky and expensive |
Considerations when measuring wrist flexion and extension[edit | edit source]
- Coupling
Coupling occurs in the wrist while performing flexion–extension and radial–ulnar deviation[12] movements. Maximal wrist range of motion is near the neutral position. The wrist should be placed at a neutral position in work station design to account for the naturally coupled wrist motion[13].
2. Open versus closed hand
Flexion
- Open hand = joint
- Closed hand = soft tissue
Extension
- Open hand = soft tissue
- Closed hand = joint
Reason to measure[edit | edit source]
The main reason to measure is that you have an accurate baseline to base your rehab and progression off.
