This study is intended to obtain the algebraic growth dynamics of the gracilis in fetuses and determine the variations of neurovascular pedicle(s) of the gracilis, to aid infant surgeries. Forty fetuses (19 males and 21 females) were included in the study. Gestational mean age of the fetuses was 22.40 +/- 2.67 (range, 18-28) weeks. Numerical values were obtained using a digital caliper and a digital image analysis software. Linear functions for the surface area, width, anterior, and posterior margin lengths of the gracilis were calculated, respectively, as: y = -289.307+20.501 x age (weeks), y = -7.113 + 0.622 x age (weeks), y = -24.421 + 3.434 x age (weeks), and y = -24.397 + 3.314 x age (weeks). In addition, length and width of the gracilis tendon were calculated as y = -6.676 + 0.934 -age (weeks) and y = -0.732 + 0.074 -age (weeks), respectively. Parameters of the gracilis had no statistically significant difference regarding side and sex (P > 0.05). In all the specimens, the gracilis was innervated by the anterior branch of the obturator nerve. Blood supply of the gracilis was identified to be derived from 1 single artery in 38 sides of total 80 (47.5%), from 2 arteries in 36 (45%) and from 3 arteries in 6 (7.5%). In 74 sides (92.5%), the nerve was superficial to the main artery, whereas in 6 sides (7.5%), it was deeper. The data of the present study could be beneficial for surgeons in infant surgeries to treat conditions such as obstetrical brachial plexus paralysis, facial palsy, or anal incontinence. Linear functions can be utilized to better evaluate the growth course of the gracilis in fetuses and to predict the dimensions thereof. Additionally, comprehending the structure and recognizing the variations of the gracilis nerves and arteries can help to protect the neurovascular pedicle(s) of the gracilis during the operations.
Quantitative Assessment of the Growth Dynamics of the Teres Major in Human Fetuses
(Springer France, 2018) Beger, Orhan; Koc, Turan; Beger, Burhan; Kayan, Gulden; Uzmansel, Deniz; Olgunus, Zeliha Kurtoglu
PurposeThe main objective of the study was to examine the use of teres major (TM) as a flap in the pediatric surgeries from an anatomical perspective by: (1) revealing the growth dynamics of the developing TM; (2) assessing the possible interconnecting structures between TM and latissimus dorsi (LD); (3) exposing the innervation patterns of TM in human fetuses.MethodsStudy was conducted on 50 fetuses (26 females and 24 males), on a mean gestational age of 22.863.21 (range 18-30) weeks. All the measurements were collected with a digital caliper and a digital image analysis software. Additionally, structural relations between TM and LD were examined in detail and further classified.ResultsNo significant difference of side and sex was detected on TM measurements (p>0.05). Linear functions for the surface area, width, length of the superior and inferior margins of TM were detected as follows: y=-257.142+18.334xage (weeks), y=-5.497+0.545xage (weeks), y=-1.621+1.068xage (weeks), and y=-2.147+1.284xage (weeks), respectively. As classified in five types, a number of 33 muscular or tendinous connections between TM and LD were detected. Musculo-tendinous slips from TM to triceps brachii (TB) were evident in four sides. Innervation of TM was observed to be providing by the lower subscapular nerve in all the cases.Conclusion p id=Par4 First, linear functions, representing the developing fetal morphometry obtained by our study can be adapted for estimating the morphometric of this muscle in early childhood. Besides, acknowledging the diverse appointments of TM with the surrounding muscles such as LD and TB may facilitate the prevention of neurovascular structures and the application of surgical procedures during tendon transfers. In brief, our findings are highly potent to bring the attention of pediatric surgeons.
