“…We believe the axis of incision will not add to visualization of contralateral reproductive structures, demanding in any case a bilateral flank incision for tubal procedures, as confirmed by Yanai [10]. In relation to a ventral midline approach, Risk [25] reports a complex disposition of abdominal muscles' aponeurosis in eutherian mammals with multiple sliding layers that could be immobilized after incision of the linea alba and suggests a parallel incision for median celiotomy. Considerations about muscular biomechanics and tissue repair were not covered in this study, making future studies necessary.…”

“…In agreement with our findings, the abdominal muscles of guinea pigs (Cavia porcellus), hystricomorph rodents closely related to capybaras, also encompass the external abdominal oblique muscle as the outermost layer, followed by the internal abdominal oblique muscle, transversus abdominis, and rectus abdominis [24], although we failed to find a detailed description of aponeurosis distribution and linea alba visibility in this species. The aponeurosis of external abdominal oblique muscle in capybaras followed the description of Risk [25] for Equidae, Bovidae, and primates. Despite the difficult identification of the linea alba in some of the post-umbilical macroscopy dissections performed here, we could confirm its presence in the pre-and post-umbilical regions through ultrasound images, corroborating the anatomical findings in eutherian mammals [25], although it might still be a challenge for the surgeon to find it during median post-umbilical celiotomy.…”

Capybaras are the largest rodents cohabiting with humans within urban and peri-urban green areas and are known by their prolificity. Surgical contraception has been recommended by official organizations as a way to control capybara populations in areas of zoonotic disease transmission, but little data are available concerning surgical anatomy. To obtain objective anatomical descriptions related to reproductive organs, eight female capybaras cadavers were dissected. The stratigraphy of the lateral (flank) and ventral, post-umbilical (on the linea alba) abdominal wall is described as well as the vascular anatomy of reproductive organs and their syntopy with the abdominal viscera. We commented on the access to the uterine tubes and uterine horns for each approach, and for better description of abdominal wall stratigraphy, abdominal ultrasonography was performed in one live female. All of the animals were provenient from “in situ” population management projects that were properly authorized. Similar abdominal wall stratigraphy was found in comparison to domestic mammals, with emphasis on a thick cutaneous muscle, a thin linea alba, and a large, loose cecum. The uterine tubes were easily accessed by bilateral laparotomy, allowing tubal removal/ligation procedures, while uterine horn exposure was more readily reached by a midline post umbilical celiotomy, favoring horn ligature and hysterotomy techniques. This study can help achieve more efficient contraceptive surgeries in capybaras, reducing the total surgical time and enhancing animal welfare.

“…As for tendinous intersections, the tendinous intersections in Zone-4 were often absent. As a regional difference in the RAM, the upper part of the arcuate line has anterior and posterior sheaths for the RAM, whereas the lower part has only anterior sheaths (Rizk, 1980). Tendinous intersections extend from the anterior sheath.…”

Formation of tendinous intersections in the human fetal rectus abdominis

Previous studies have poorly described the initial development process of the tendinous intersections of the rectus abdominis muscle (RAM). The present study aimed to observe the formation of tendinous intersections in the RAM during the early fetal period using diffusion tensor imaging (DTI). Fifteen human fetal specimens (crown‐rump length [CRL]: 39.5–93.7 mm) were selected. Three‐dimensional measurements revealed that Zone‐4 (i.e., the zone between the pubic symphysis and the caudal base of the umbilical ring in the RAM) had a smaller width and was thicker than Zone‐1 and Zone‐2 (i.e., the zones between the costal arch and the cranial base of the umbilical ring) and Zone‐3 (i.e., the zone at the umbilical ring). Characteristics of tendinous intersections in the RAM during the early fetal period were assessed according to number, size, type, laterality, and sex. The mean number of tendinous intersections on both sides was 3.1 (range: 2.0–4.0), and 21% of specimens had only two tendinous intersections, which was higher than that reported in previous adult studies. The present data suggest that the formation of tendinous intersections was still in progress in specimens with two tendinous intersections in the RAM and that the third tendinous intersection was formed in Zone‐2. Ordinal logistic regression via generalized estimating equations revealed that the odds for a higher type of tendinous intersections in Zone‐1 and Zone‐2 were significantly higher than those in Zone‐4 (adjusted odds ratio: 14.85, 8.84). The odds for the presence of incomplete types (tendinous intersections that could not completely transverse the RAM) in Zone‐3 were significantly higher than those in Zone‐1 (adjusted odds ratio: 7.4). The odds for missing tendinous intersections in Zone‐4 were significantly higher than those in Zone‐1 (adjusted odds ratio: 20.5). These zonal differences in the formation of tendinous intersections were consistent with those observed in previous adult studies. In this study, DTI detected tendinous intersections in a sample with a CRL of 45.8 mm (approximately 11 weeks of gestation), which is earlier than that in previous histological findings, indicating that the RAM does not have mature tendinous intersections until the 17th week of gestation. In conclusion, DTI could detect the premature differentiation of tendinous intersection formation. Our data may aid in elucidating the developmental processes of tendinous intersections in the RAM.

Zusammenfassung Hintergrund Die sensomotorische Fazilitation über die Hände ist eine Methode, die mutmaßlich die Rumpfmuskulatur aktiviert und somit eine Alternative zur Kurzfußtechnik nach Janda darstellen soll. Nach Reliabilitätsuntersuchungen zur Messmethode soll hier der Nachweis einer Erhöhung der Muskelaktivität mittels Oberflächen-EMG (OEMG) erbracht werden. Methoden Mittels OEMG wurden bei 44 jungen gesunden Probanden das Aktivierungsverhalten von 15 Muskelpaaren während der Fazilitation im Vergleich zur Ausgangsstellung geprüft. Ergebnisse Die Fazilitation über die Hände führte zu einer Aktivierung der Rumpfmuskulatur, die weitgehend symmetrisch erfolgte und für die überwiegend eine klinische Relevanz nachweisbar war (Effektstärken>0,8). Seitensymmetrische Unterschiede im Rahmen der Händigkeit zeigten ein höheres rechtsseitiges Aktivitätsniveau. Die weiblichen Studienteilnehmer reagierten im Detail anders als die männlichen Teilnehmer. Diskussion Zur Vermeidung einer verstärkten asymmetrischen sensomotorischen Fazilitation auf Grund der Händigkeit ist eine therapeutische Kontrolle, zumindest zu Beginn der Behandlung, sinnvoll. Die beobachteten geschlechtsspezifischen Besonderheiten können derzeit nicht aufgeklärt werden und erfordern weitere Untersuchungen. Systematische Untersuchungen zur Seitendominanz in ihrer Auswirkung auf die posturale Rumpfmuskulatur existieren nicht, dennoch können die beobachteten generellen Seitenabweichungen der Händigkeit zugeordnet werden. Schlussfolgerung Die HIP eignet sich zur Fazilitation der Rumpfmuskulatur. Weitere Untersuchungen an der eigentlichen Zielgruppe, bspw. Rollstuhlfahrer, sind notwendig um die Aspekte gehandicapter Personen weiter zu erfassen.
