“…The material was stored in a darkened room -a specialized max -maximal value in centimeters; SD -standard deviation laboratory with constant temperature and no exposure to light. The method of storing and preserving the material did not change throughout the period from the acquisition of the material to its use for scientific purposes (Karykowska et al 2021;Suchanecka et al 2022;Ziółkowski et al 1994).…”

Introduction: The Flexor Carpi Ulnaris (FCU) is a part of the palmar the forearm muscle group and one of the most important muscles for upper limb functioning - is responsible for flexion and adduction of the hand at the radio-carpal joint. There are clinically significant but rare anatomical variations of FCU. The variability of the FCU has not been described up to now, and no typology of the muscle based on its more variable terminal attachment has been created. Aim of the study: Determination of FCU muscle typology based on available fetal material. Material and methods: A total of 114 human fetuses (53 female, 61 male) between 117 and 197 days of fetal life were eligible for the study. Preparations were carried out using classical anatomical techniques based on a previously published procedure. Thanks to that significant anthropometric landmarks were visible for the gathering of metric measurements. Metric measurements were taken and statistically analysed using R-Project software. Results: A new typology was created based on variable muscle insertions. Additionally, the presence of an atypically located, additional, separated muscle belly was described. A comparison of measurements of the left upper limb in relation to the right upper limb showed significant differences for forearm length to the anthropometric point of the stylion radiale, limb length, total FCU length and FCU length which means that the left limb is longer than the right limb. A comparison of FCU insertion types between left and right upper limb showed there’s no significant difference between counts of each type. Conclusion: The FCU is a muscle that is easy to palpate and may therefore act as a topographical marker for healthcare professionals. Knowledge of its variability is not only of theoretical importance but also has clinical significance. The current publication demonstrates presence of variability in FCU terminal attachment. Certainly, this topic requires further research and continued work on a detailed understanding of forearm anatomy in the fetal period.

“…The super cial bular nerve (SFN) supplies motricity to peroneus longus and peroneus brevis muscles [15], just as the sensibility of most of the anterolateral leg and dorsum of the foot [9]. It arises at the branching of the common bular nerve [37] and courses through the lateral compartment of leg [33].…”

Branching patterns of the superficial fibular nerve: an anatomical study with meta-analysis

et al. 2022

Purpose: To investigate variations in the branching patterns of the super cial bular nerve (SFN) in regard to the deep fascia of the leg and to the ankle joint level.Methods: A broad literature search was conducted in PubMed, Scopus, Lilacs, and Web of Science databases on October 14 th , 2021. PRISMA guidelines have been followed throughout this review. Articles with data on SFN variations prevalence were included. The data were extracted and pooled into a metaanalysis. The authors also dissected a total of 64 formalin-xed Brazilian fetuses (n = 124 lower limbs).Results: Twenty-ve studies (n = 1272 lower limbs) comprised this review. Concerning the SFN branching at the deep fascia, type 1 variation (the SFN pierces the fascia as a single nerve trunk) had a pooled prevalence of 86.4% (95% CI 84.5-88.2), while type 2 had a pooled prevalence of 13.6% (95% CI 11.8-15.5). At the ankle joint level, type 2 variation (the SFN splits in its terminal branches after cross the joint) was the most common pattern, with a pooled prevalence of 78.7% (95% CI 74.5-82.7). Conclusion:In the most prevalent anatomical pattern, the SFN branching between its exit site from the deep fascia and the level of the ankle joint. These variants have great clinical signi cance.
