7.2.7 Integrated Functions in the Upper Limb

Hand as a mechanical organ:

important types of grip;
opposition;
axis of the hand;
position of function;
role of pronators and supinators.

Implications for hand function of major nerve injuries.
Importance of fixation of other joints in the limb to support the hand.
Hand as a sensory organ.

7.2.8 Skills and Procedures

7.2.8.1 Clinical examination

Major bony landmarks, esp. around shoulder and elbow
Nerve function (muscle action and power, nerve reflexes e.g. biceps). Main sensory supply.
Identification of principal pulse pressure points as surface landmarks.

7.2.8.2 Imaging

Plain radiographs: identification of principal bony landmarks (see previous sections).
CT and MRI scans: identification of principal structures and landmarks.
Contrast radiographs; angiographs, identification of principal arteries, veins, lymphatics. Arthrograms.

7.2.8.3 Special Investigations

Testing motor and sensory innervation Electromyograms.

7.2.8.4 Clinical procedures

Venepuncture and venous cannulation: points of access.

Measurement of systemic arterial pressure

Rationale for positioning of joints when setting in plaster after fracture.
