Figure 2.

Electron micrographs of the posterior interosseous nerve, with diagram of size distribution of myelinated nerve fibres, from patients with CTS, where the individuals are healthy (a), have type 2 diabetes (b) or type 1 diabetes (c). The arrows in the upper panels indicate regenerative clusters. In the diagram on the lower panels, the size distribution of myelinated nerve fibres is based on the micrographs from the upper panels, indicating a redistribution of nerve fibres. Scale bar = 20 µm.
