“…This differed from the current study, which showed that the most common place of bifurcation of the MCN was the TN, and is supported by various studies. [9,12,[21][22][23] Variations in the TN branching pattern and location were seen, in concordance with previous studies. A wide range of classification systems have been reported; Louisia and Masquelet [23] described 2 branching patterns at the level of MCA, Havel et al [8] observed 9 patterns, and Dellon et al [24] found 21 modes of bifurcation patterns.…”

It is essential to understand the considerable variations in bifurcation patterns of the tibial nerve (TN) and its peripheral nerves at the level of the tarsal tunnel to prevent iatrogenic nerve injury during surgical nerve release or nerve block. A total of 16 ankles of 8 human cadavers were dissected to investigate the branching patterns of the TN, using 2 imaginary lines passing through the tip of the medial malleolus (MM) as reference lines. Bifurcation patterns and detailed information on the relative locations of the medial plantar, lateral plantar, medial calcaneal, and inferior calcaneal nerves to the reference lines were recorded. The most common bifurcation pattern was Type 1 in 12 ankles (75%), followed by Type 2 in 2 ankles (13%). One medial calcaneal nerve (MCN) was seen in 11 (69%) specimens and 2 MCN branches were seen in 5 (31%) specimen. 88% of the MCN branches bifurcated from the TN, whereas 6% originated from both TN and lateral plantar nerve (LPN). At the level of the tip of the MM, 2 of 7 parameters showed statistically significant difference between both sexes (P < .05). There was a statistically significant difference between left and right ankles in 2 of 7 measurements (P < .05). Further morphometric analysis of the width, distance, and angle between the TN branches and the tip of MM showed a highly variable nature of the location of the peripheral nerve branches.

“…Damage to the ADMM nerve was first reported in 1940 by Roegholt 18 and has subsequently been confirmed by numerous authors [1, 4, 8, 11–18]. The damage has been postulated to occur in one of two locations: either at the point where the nerve changes direction at the inferior margin of the abductor halluces, where it is compressed between the abductor hallucis and the medial side of the quadratus plantae, or slightly more distal, where the nerve passes anterior to the medial process of the calcaneal tuberosity [4, 14].…”

BackgroundThe nerve to the abductor digiti minimi muscle (ADMM nerve) is the first branch of the lateral plantar nerve or originates directly from the posterior tibial nerve. Damage to the ADMM nerve is a cause of heel pain and eventually results in ADMM atrophy. It is known that ADMM atrophy occurs more often in females than in males, and the reason remains unclear. This study aimed to explore sex differences in the branching pattern, position, and angle of the ADMM nerve.MethodsForty-two cadavers (20 males, 22 females) were dissected at Aichi Medical University between 2011 and 2015. Cases of foot deformity or atrophy were excluded and 67 ft (30 male, 37 female) were examined to assess the branching pattern, position, and angle of the ADMM nerve.ResultsThe branching positions of the ADMM nerve were superior to the malleolar–calcaneal axis (MCA) in 37 ft (55 %), on the MCA in 10 ft (15 %), and inferior to the MCA in 20 ft (30 %). There was no case among male feet in which the ADMM nerve branched inferior to the MCA, whereas this pattern was observed in 19 of 37 female feet (51 %). The branching position of the ADMM nerve was significantly closer to the MCA in female feet than in male feet. There were no significant sex differences in the branching pattern and angle of the ADMM nerve.ConclusionsThe ADMM nerve sometimes branches off inferior to the MCA in females, but not in males. This difference may be the reason for the more frequent occurrence of ADMM atrophy in females than in males.

“…The patient presents with heel pain that radiates along the inner aspect of the calcaneus to the medial arch of foot [26,60]. The diagnosis is established by eliciting tenderness of the nerve on the inside of the heel and a positive Tinel's sign [10,39,64].…”
