“…For the treatment of entrapment syndromes, decompression or fasciotomy can be applied (Kernohan et al, 1985;Sridhara and Izzo, 1985;Styf, 1989). Thus, it is essential to know the relation of the SFN and its branches with the crural fascia.…”

Branching patterns of the common and superficial fibular nerves in fetus

2005

In this study, we focused on finding out whether branching patterns of the common fibular (CFN) and superficial fibular (SFN) nerves change throughout the early period of life. The popliteal fossa and legs on both sides of 20 fetuses (13 females and 7 males) were dissected. The ages of the fetuses varied between 20 and 36 weeks. The levels where the CFN diverged from the sciatic nerve, the CFN diverged to its terminal branches, and the cutaneous branches of the SFN became superficial and diverged were evaluated, together with the similarity of the patterns of these nerves on both sides. We observed that, comparing with the results of previous studies on adults, both the sciatic and the CFNs in the fetuses were diverging into their terminal branches more distally. Additionally, the SFN appeared to become superficial more proximally in the fetus than in the adult. SFN was piercing the crural fascia before diverging into its terminal branches in 29 legs. Only in 8 of them, it was becoming superficial within the middle one-third of the leg, which was observed more frequently in males (42.9% of 14 legs) than in females (13.3% of 15 legs). But there was no statistically significant gender difference (P = 0.07). The medial dorsal cutaneous (MDCN) and intermediate dorsal cutaneous (IDCN) nerves which were piercing the crural fascia separately were observed in 27.5% of the subjects, all females. In these, MDCN was piercing the fascia superior to the level where the SPN becomes superficial, whereas the IDCN was piercing it to a level lower to this and always in the inferior one-third of the leg. We suggest that the detailed information about the branching patterns of the CPN and SPN in early ages will be beneficial, particularly in tumor and deformity surgery. The reason for different patterns and piercing levels of the nerves may be the effect of the elongating extremity during aging that enforces the fascia and modifies its position with a more stable structure, the nerve.

“…There are many reports of proximal superficial peroneal lesions presenting as a distal superficial peroneal neuropathy. Most of these reports dealt with entrapment of the superficial peroneal nerve at the fascial opening in the lower leg, and in none of these cases was any nerve conduction study performed 8, 11, 12, 22, 23. Laurencin et al9 reported one case of schwannoma of the superficial peroneal nerve at the fascial opening presenting as pain and dysesthesia on the fourth toe and fourth web space.…”

The superficial peroneal nerve subserves sensation on the entire surface of the dorsum of the foot, except in small areas. All previously reported techniques for evaluating nerve conduction along this nerve tested a proximal portion of the nerve. We report a new method for evaluating sensory nerve conduction of the four branches of the distal superficial peroneal nerve. Two branches to the second and third toes of the medial dorsal cutaneous nerve and two branches to the fourth and fifth toes of the intermediate dorsal cutaneous nerve were studied orthodromically and antidromically in 37 feet of 21 normal volunteers using surface stimulating and recording electrodes and with a distance of 10 cm between the stimulating and recording electrodes. Maximum nerve conduction velocities (NCV) ranged from 41.8 to 46.9 m/s, and mean response amplitude ranged from 6.5 to 7.6 microV with the orthodromic technique. Values for NCV were almost identical when elicited by antidromic and orthodromic techniques, but response amplitudes were higher with the antidromic technique. Mean amplitudes of the distal superficial peroneal nerve were about 50% of the proximal superficial peroneal, and the conduction velocity in the distal superficial peroneal was slower than that in the proximal superficial peroneal nerve, by 8-14 m/s. In seven cases, distal superficial peroneal neuropathy was confirmed with this technique: two with proper digital neuropathy, two with medial dorsal cutaneous neuropathy, and three with intermediate dorsal cutaneous neuropathy.

“…Although routine radiography may not show the lesion, a positive bone scan may be obtained. With pain in the proximal forefoot, consideration should also be given to entrapment neuropathy of the deeper superficial peroneal nerves [39][40][41] which may be sustained after injury to the dorsum of the foot or the anterior aspect of the lower leg. A positive nerve-percussion test and associated neuritic symptoms with decreased sensation in the distribution of the involved nerve may give clues to this diagnosis.…”
