- There are two commonly used classifications for PNI- the Seddon Classification and the Sunderland Classification. Seddon is responsible for classifying peripheral nerve injuries into neuropraxia, axonotmesis, and neurotmesis. Sunderland expanded this idea by further classifying these into different degrees or levels of injury.

There are two commonly used classifications for PNI- the Seddon Classification and the Sunderland Classification. Seddon is responsible for classifying peripheral nerve injuries into neuropraxia, axonotmesis, and neurotmesis.
Nerve injury classification assists in prognosis and determination of treatment strategy for nerve injuries. Classification was described by Seddon in 1943 and by Sunderland in 1951. In the lowest degree of nerve the nerve remains intact, but signaling ability is damaged, termed neurapraxia.
Learn about the five degrees of peripheral nerve injury based on the effect of the injury on the axon and connective tissue. The classification was expanded by Sunderland in 1951 from the original three degrees by Seddon in 1943.
Aug 7, 2023 · On the other hand, the Sunderland classification has five grades based on the severity of the injury. The first corresponds to neuropraxia in Seddon’s classification and includes nerve conduction block due to focal myelin sheath disruption.

Jun 15, 2024 · Learn about the causes, mechanisms, and outcomes of peripheral nerve injuries and repairs in the hand. The web page does not mention the Sunderland classification, which is a system for grading nerve injuries based on the degree of axonal disruption.
The two widely used major classifications for nerve injury grading are the Seddon and Sunderland classifications.[4,5,6,7] While Seddon classification is simpler to follow and more relevant to electrophysiologists, Sunderland grading is more often used by surgeons to decide when and how to intervene.
SUNDERLAND CLASSIFICATION. The Sunderland classification is based on the degree of tissue injury. 13, 23-25 There is considerable overlap with the Seddon classi-fication. First-degree Injury. This corresponds to Seddon's neurapraxia. Axonal conduction is temporarily blocked, and all tissue compo-nents of the nerve trunk are intact.
