Afferent and Efferent Fibres in the Putative Caudal Cutaneous Femoral Nerve in the Sheep

SummaryAnatomical dissections supported by neurophysiological recordings have shown the putative caudal cutaneous femoral nerve in the sheep, when present, to contain afferent and efferent nerve fibres passing in both directions between the pudendal and sciatic nerves. Fascicles from the ventral branches of one or more sacral spinal nerves may join this interconnection directly: other fascicles either bypass the interconnection, or arise from it, and pass distally to innervate muscle and/or skin. We suggest that the interconnection should be regarded simply as part of the lumbosacral plexus.

Meralgia Paresthetica From a Wallet

To the Editor.— Dr J. R. Boyce's 1 informative letter, Meralgia Paresthetica and Tight Trousers, recalled to mind similar symptoms I recently experienced. Having grown up near the inner city, I soon learned that if a wallet was carried, it was safer in the front than in the rear pants pocket. This compromise, coupled with a chronically thin wallet, caused no problems until after completion of medical school and postgraduate education. As credit cards and membership cards proliferated, I noticed an aching, burning sensation along the left anterolateral thigh on the side of the wallet. It also was worse while driving any distance. This continued for months. Thinning the wallet of superfluous papers and even buying a thinner wallet didn't help. However, after switching the wallet to the back pocket (after all, what's worth more, your money or your health?), the symptoms abated. Apparently once the lateral cutaneous femoral nerve

Anatomical and technical refinements for abdominoplasty

Several important details pertinent to the classic transversal low-incision abdominoplasty, commonly underestimated, are pointed out. Metameric sensitivity distribution is focused in the normal individual and then transformed by abdominoplasty. Emphasis is also given to the vascularization, lymphatic drainage, and treatment of the muscle-aponeurotic plane and femoral cutaneous nerve under effects of abdominoplasty. Attention is called to how effectively they can help to obtain symmetric postoperative results and how important it is to have a normal-looking, aesthetically pleasing navel. First introduced as a corrective procedure for abdomens grossly deformed by lipodystrophies or greatly compromised by hernias or problems related to multiple surgeries, abdominoplasty is no longer merely a reconstructive procedure. In the last 10 years, requests for abdominoplasty for aesthetic improvement of lax skin, "striae," and scars of even "good quality" situated in the infraumbilical area have increased in indirect proportion to the size of today's bathing suits.The great number of cosmetic abdominal surgeries calls for a better solution to problems such as the placement and quality of scars, the positioning of the umbilicus, and the resulting waistline. An increasing number of demands are made regarding minute details of asymmetry, sensibility, edema, and pain. Like the young surgeon in training, we had to search our anatomy books to find explanations and ways to avoid problems justifiable in earlier days but unacceptable today.

MERALGIA PARESTHETICA DUE TO PRESSURE OF THE CORSET

Meralgia paresthetica, described independently in 1895 by Bernhardt and Roth, although an unusual, can scarcely be considered a rare condition, inasmuch as Musser and Sailer have reported ten cases personally observed. The peculiar disturbance of the external cutaneous femoral nerve characterized by paresthesia, or more or less severe pain when the individual is in the erect position, has been ascribed to various causes. Bernhardt considered a toxic neuritis as the most important factor, as he and others have reported cases following the acute infections, especially typhoid. Others have considered pure mechanical factors as the more important; the peculiar curve of the nerve and its relation to the surrounding structure render it especially liable to compression when the thigh is extended. Roth has called attention to the following points along the course of the nerve where trauma of this character may occur: first just after the exit of the
