This table shows the details of all nerves assessed. Each line represents data from one nerve. Recipient nerves are listed first: (PIN) posterior interosseous, (AIN) anterior interosseous and (TRI) triceps. Donor nerves (bolded text) comprise (SUP) supinator, (BRA) brachialis, (ECRB) extensor carpi radialis brevis, (TM) teres minor and (Pax) Posterior axillary nerve. The status of nerves in column (C) 3 is depicted as follows: colours denote a group of features with respect to axon density and extent of myelin changes as described below, with $\text{N}$ representing relative normal specimens and $\text{N}$ $\text{N}$ $\text{N}$ $\text{N}$ increasing severity of changes in specimens, A(<) denotes a reduced axon density. The other colours represent other individual features observed as described below: $\text{N}$ = specimens with a good axon density/size/myelin thickness and few if any myelin abnormalities, $\text{N<}$ = a notably reduced axon density/size/myelin thickness and few if any myelin abnormalities, $\text{N}$ = good or $\text{N<}$ reduced axon density, and up to 50% axons with thickened, folded, split myelin, $\text{N<}$ = reduced large axon density and over 50% axons with thickened, folded, split myelin, $\text{N<}$ = markedly reduced axon density and axon size, thickened perineurium, oedematous endoneurium and the presence of $\text{RB}$ (Renaut bodies) C7. The % of axons associated with thickened/split/folded myelin is shown in C4. Other myelin abnormalities include $\text{LDA}$ (large demyelinated axons) and $\text{D}$ (degenerating axons) in C5. Semi-quantitative assessment of unmyelinated axon numbers (+ to +++) in C6. Observation of “inflammation” $\text{I}$ (intravascular and extravasated mononuclear blood cells) C8. Axon orientation is (T = transverse), (L = longitudinal) C9.
