RESUMO
ABSTRACT: Some patients present with clinical symptoms of localized tenderness and pain associated with a specific peripheral nerve, such as the ulnar nerve at the elbow or the sciatic nerve, which has been called, although rarely, "Valleix point" or "Valleix phenomenon". The purpose of this article was to translate and research the 719-page book "Traité des névralgies ou affections douloureuses des nerfs" dated 1841, dedicated solely to nerve pain (neuralgia), written by the French physician François Louis Isidore Valleix (1807-1855). He may have been the first person to observe and describe this phenomenon of localized pain, but he was probably also the first to describe distal nerve radiation, which he called "élancement" or lancinating, or stabbing. He described the phenomenon of a nerve producing pain at points along its course that we now understand to be sites of compression, clearly describing cubital and fibular tunnel syndromes, which he called neuralgias. He also described some rarer sites of compression, such as supraorbital and occipital neuralgia, notalgia paresthetica, and ACNES, but he did not describe the most common site of compression today, the median nerve at the wrist. Valleix's descriptions are clear and precede the classic 1915 reports of Hoffmann's and Tinel's signs by 74 years.

BACKGROUND: This study investigated the relative cost utility of three techniques for the management of symptomatic neuromas after neuroma excision: (1) implantation of nerve into muscle, (2) targeted muscle reinnervation (TMR), and (3) regenerative peripheral nerve interface (RPNI). METHODS: The costs associated with each procedure were determined using Common Procedural Terminology codes in combination with data from the Centers for Medicaid and Medicare Services Physician and Facility 2020 Fee Schedules. The relative utility of the three procedures investigated was determined using changes in Patient-Reported Outcomes Measurement Information System (PROMIS) and Numeric Rating Scale (NRS) pain scores as reported per procedure. The relative utility of each procedure was reported in terms of quality-adjusted life years (QALYs), as is standard in the literature. RESULTS: The least expensive option for the surgical treatment of painful neuromas was nerve implantation into an adjacent muscle. In contrast, for the treatment of four neuromas, as is common postamputation, TMR without a microscope was found to cost $50,061.55 per QALY gained, TMR with a microscope was found to cost $51,996.80 per QALY gained, and RPNI was found to cost $14,069.28 per QALY gained. While RPNI was more expensive than nerve implantation into muscle, it was still below the standard willingness-to-pay threshold of $50,000 per QALY, while TMR was not. CONCLUSION: Evaluation of costs and utilities associated with the various surgical options for the management of painful neuromas suggest that nerve implantation into muscle is the least expensive option with the best improvement in QALY, while demonstrating comparable outcomes to TMR and RPNI with regard to pain symptoms.
RESUMO
In the Old Testament book of Genesis, Chapter 32, Jacob wrestled with an angel. After that encounter, Jacobs limped. Through careful understanding of the original meaning of the words in Verses 25, 31, and 32 of Genesis 32, we seek to learn what type of injury the angel might have inflicted on Jacob. At the time Genesis was written, the difference between tendon and nerve was not understood. While wrestling, when the angel's hand grabbed Jacob, it was most likely Jacob's hip that was affected, not his thigh. Most likely, there was a posterior dislocation of the "socket" (hip joint), and the "sinew" that was damaged was the sciatic nerve. Today, this biblical description is manifested by the sciatic nerve being removed for beef to be considered Kosher. LAY SUMMARY: In Genesis Chapter 32, Jacob wrestled with an angel, after which Jacob limped. Most likely, Jacob had a posterior hip dislocation with a sciatic nerve stretch injury. Today, this Biblical description is manifested by the sciatic nerve being removed for beef to be considered Kosher.
