AbstractThe aim of the study was to determine the position of motor branches of the nervus fibularis superficialis (NFS) in relation to the main axis of the trunk of this nerve in human foetuses. The possible occurrence of sexual dimorphism and symmetry in the course of NFS branches was also determined. The study was performed according to the Declaration of Helsinki and approved by the Local Bioethics Committee. The standard preparatory analysis was performed on 207 human foetuses (101 females) aged from 113th day (5th month of foetal life) to 222nd day (8th month of foetal life) Based on the performed analysis, four basic types of arrangement of muscle branches derived from NPS were proposed: bipinnate type ‐ at least 3 motor branches located on both sides of the nerve trunk, unipinnate type ‐ at least 2 branches located on one side of the trunk, the pitchfork type ‐ one motor branch on both sides and other type. In each types the lower branches were responsible for innervation of fibularis brevis muscle. An analysis of the frequency of occurrence of particular types of muscle branch positions showed that the most frequent is the bipinnate type. The unipinnate type is almost half as common and the pitchfork type is the least common. Individual types were symmetrical in both extremities in most cases. There were no statistically significant gender differences both in the right (χ=0.877, p = 0.645) and left (χ=1.263, p = 0.738) limbs. An important novelty of this paper is the presentation of the typology of NPS based on broad fetal material. The cognitive significance of this study is therefore important and allows to directly determine the course and division of NPS in the perspective of prenatal development and perinatal surgery.
