Examination of Radial Nerve
2 questions that are relevant to ask that are allowed in short case practical examination are
(same holds true for all nerve related questions )
1. What happened ?
2. When it happened ?
if allowed ask
3. what are the difficulties for the patient
( Then introduce yourself , ask for permission to proceed and go to examination after proper examination )
Look- Scar
Wasting of triceps , forearm radial borders
Feel - Temperature
tenderness - Superficial and deep
Tinel's sign - v. v.v. important
check pliability of scar and scar tenderness, check tinel's on scar
check bony union if there was a previous sign of fracture
Lymph nodes
Pulsation / Allen's test
Movement
quickly assess upper extremity movements
Measurement
quickly assess humerus shortening or shortening of forearm
Neurovascular examination
Sensation
Autonomous zone of all 3 nerves in UE
Muscle power asessment
Elbow Triceps
Forearm - Supinator , Pronator Teres , Brachioradialis
Wrist - ECRL , ECRB , ECU, PL , FCU , FCR
Hand
Thumb
EPL, EPB, Abductor Pollicis ,
Finger
EDC , FDS , FDP
Not to miss quickly median nerve and ulnar nerve screening.
Reflexes
Radial and Ulnar artery Pulsation important
Allen's test is important too .
This way all donor muscles are also tested quickly together while testing muscles supplied by radial
nerve so as to finish in time.
Donor tendons for radial nerve palsy are
Pronator Teres
PL , FCR , FCU
FDS , 3rd and 4th finger
