The median nerve crosses the ulnary artery, from which it is separated by the deep head of the pronator teres muscle, at the upper part of the forearm. It descends through the forearm lying over the flexor digitorum profundus muscle, until reaching the flexor retinaculum, being accompanied by the median artery (Figures 1.31C, and 1.64). At the lower part of the forearm, it lies between the tendons of the flexor carpi radialis and the flexor digitorum sublimis muscles, behind and slightly lateral to the tendon of the palmaris longus muscle (Figure 1.67).
Pure Autonomic Failure
Published in David Robertson, Italo Biaggioni, Disorders of the Autonomic Nervous System, 2019
Nanda et al. (1976, 1977) studied the adrenergic fibres of blood vessels of the quadriceps and palmaris longus muscles. They, in contrast to the above studies, showed that normal catecholamine histofluorescence was present in two patients with probable PAF and one patient with SDS. One patient with PAF had an unusual disorder characterized by normal parasympathetic and sympathetic cholinergic function, but the inability to release noradrenaline in response to postural change and indirect sympathomimetic agents. Furthermore, three patients with SDS in this report had an absent perivascular catecholamine histofluorescence.
Free Transplantation of Striated Muscle
Published in Han C. Kuijpers, Colorectal Physiology: Fecal Incontinence, 2019
The aim of the operation is to place a muscle graft as a sling around the rectum, so as to mimic the position and function of the puborectalis muscle.20 The transplant must be in contact with normally innervated levator ani muscles to permit reinnervation. The procedure is carried out in two stages, with an interval of 2 to 3 weeks. In the first stage, denervation of the muscle intended as a graft is made. In the second, the transplantation is performed. The muscle of choice is the palmaris longus muscle of the forearm. If this muscle is congenitally absent other muscles, e.g., the sartorius muscle can be used.

In addition to partial skin grafts, total skin grafts (mostly from the inguinal region as donor site) account for nearly 200 procedures (Figure 4(a,b)). Nine ilioinguinal flaps (5 boys and 4 girls with a mean age of 11.2 years, range 2–16 years) have been chosen as therapeutic option in severe defects of the dorsal aspect of the hand (Figure 5(a–d)). 5 tendon transfers (4 boys and one girl with a mean age of 15.4 years, range 12–19 years) were performed in a very heterogeneous array of techniques to draw any conclusions and some controversy persists about the most appropriate moment for intervention. We favour lengthening in sliding/bayonetted fashion but we have used grafting after harvesting material from tensor fascia lata, plantaris and palmaris longus muscles. These techniques were inspired by previous experience of the senior authors with leprosy cases. 3 resections of the first carpal row (2 girls and 1 boy with a mean age of 8 years, range 4–15 years, all right-handed) in extreme cases of wrist ankylosis have been an unusual means to tackle with particular, severe cases (Figure 6(a–c)).
