The core principle is a mnemonic association model correlating specific upper extremity peripheral nerves (Axillary, Radial, Median, Ulnar) with their corresponding anatomical origins (C5-T1), etiologies of injury, and clinical manifestations within the domain of neuroanatomy. This theoretical framework establishes formal definitions linking fracture locations such as surgical neck fractures or supracondylar breaks to specific deficits like wrist drop or ape hand deformity based on nerve pathway compression. The concept functions as a rule-based mapping mechanism essential for diagnosing peripheral neuropathies and predicting functional motor loss in the upper limb following traumatic insults.
