Item Popliteal artery: Anatomical study and review of the literature(Annals of Anatomy, 2020) Aragonés Maza, Paloma; Rodríguez-Niedenführ, Marc; Quinones, Sara; Simón de Blas, Clara; Konschake, Marko; Sañudo Tejero, José Ramón; Vázquez, María TeresaBackground The frequency of appearance of anatomical variability in the terminal division of the popliteal artery (PA) is different according to the type of sample used, and ranges from 2% to 21%. The PA locates 1,01 cm behind to the lateral meniscus, which makes it vulnerable during surgical procedures. Iatrogenic injury of the PA or its terminal branches increases if anatomical variables are present. Our aim was to describe and review the branching pattern of the PA in a body-donors to science sample to determine the influence of the sample used (body-donors vs imaging test). Methods A sample consisting of 260 popliteal regions, corresponding to 130 corpses (66 women, 64 men), have been dissected. Multivariate analysis was carried out. Results The terminal division of the PA was classified as follows: Pattern 1: the PA divided into the anterior tibial (ATA) and the posterior tibial arteries (PTA) at the level or distal to the lower border of the popliteal muscle (PM) (94.7%). Pattern 2: the PA bifurcated into the ATA and PTA, proximal to the lower border of the PM (3.3%). Pattern 3: the PA divided at the same level into the ATA, PTA and PEA. (2%). No significant differences between gender and side of the limb could be find. Conclusions We propose a classification that encloses three identifiable groups only. This will allow clinicians to bear in mind these variables easily, at the same time avoiding injuries during surgical procedures such as lateral meniscus repair.Item Variant plantaris muscle with degenerated accessory head: Gross and histological analysis(Anatomia Histologia Embryologia, 2023) Futa, Brianne A.; Olewnik, Lukasz; Konschake, Marko; Cardona, Juan J.; Iwanaga, Joe; Aragonés Maza, Paloma; Sañudo Tejero, José Ramón; Tubbs, R. ShaneThe variant plantaris muscle has itself been reported to have variable presentations. Here, we report an unusual finding of the plantaris muscle and report its gross and histological findings. A duplicated head of the plantaris muscle was identified in the right leg of an adult cadaver age and sex. The more anterior head of the muscle was in the typical location and originated from the superolateral condyle of the femur. However, the more posteriorly located head arose from the iliotibial band at the level of the distal thigh. The two heads united and continued as the typical distal tendon of the plantaris muscle to insert into the calcaneus tendon (Achilles). The normally positioned head of the plantaris muscle was found to be composed of typical skeletal muscle fibres. However, the accessory head of the plantaris muscle was found to be severely degenerated and infiltrated with adipose tissue. We report a duplicated head of the plantaris muscle. Histologically, the accessory head was degenerated and infiltrated with adipose tissue. To our knowledge, this is the first report of such a case. Further cases are now necessary to further elucidate this finding.Item The medial arm fasciocutaneous flap: a wasted alternative?(European Journal of Anatomy, 2021) Vidal, A.M.; Sañudo Tejero, José Ramón; Quinones, S.; Konschake, Marko; García Pumarino, R.; Aragonés Maza, PalomaThe medial side of the upper arm is supplied by perforator arteries arising from the brachial artery, the superior ulnar collateral artery and the artery to the biceps muscle. Fasciocutaneous flaps from the medial arm region could be designed based on these perforating arteries, but the anatomical variability of this region has led to a loss of interest in it as a donor area for fasciocutaneous flaps. The aim of this study is to identify, through cadaveric dissection, whether there are constant perforator arteries from the brachial artery that could be used to raise fasciocutaneous flaps from the inner side of the arm. For this purpose, 15 upper extremities belonging to body-donors have been dissected. Six extremities were right-side arms and six belonged to female donors. 7 parameters and the differences between gender and side of the upper extremity were studied (distances from the acromion and the coracoid to the beginning and to the end of each perforating artery, distance from the insertion of the distal tendon of the biceps muscle to the origin of each perforator artery, length and diameter of the perforators arteries). Perforator arteries arising from the brachial artery to the inner face of the arm were found in all the upper limbs dissected. The median number of these perforator arteries found by the upper limb was 5±1.9 (range 3-9). Anatomical variations consisted of the number of perforator arteries that were found in each limb. Only in 2 arms (13.3%), the perforator arteries arose from a superficial brachial artery or from the distal part of the brachial artery. The mean diameter of the perforating artery was 1.80±0.58 mm, and the mean length resulted in 4.67±2.07 cm. The consistent vascular anatomy found for these perforator arteries, arising from the brachial artery, and the easy landmarks described justify the use of fasciocutaneous flaps of the medial side of the arm for reconstructive surgery.Item Relationships among Coracobrachialis, Biceps Brachii, and Pectoralis Minor Muscles and Their Correlation with Bifurcated Coracoid Process(BioMed Research International, 2022) Zielinska, Nicol; Tubbs, Shane; Podgórski, Michał; Konschake, Marko; Aragonés Maza, Paloma; Grzelecki, Dariusz; Olewnik, LukaszThe aim of this study is to demonstrate the relationship between the proximal attachment of the coracobrachialis muscle and the short head of the biceps brachii and the distal attachment of the pectoralis minor. Their correlation with the bifurcated coracoid process (CP) will be also assessed. On the basis of these observations, a new classification of structures attached to the coracoid process is proposed. Classical anatomical dissection was performed on one hundred forty-five upper limbs. Three types of relationship between the coracobrachialis muscle and the short head of the biceps brachii were observed in the cadavers. In type I (occurring in 54%), the coracobrachialis and the short head of the biceps brachii created a common junction attached to a single CP. Type II was divided into two subtypes (a and b). Subtype IIa (frequency 10%) was represented by independent proximal attachments of the short head of the biceps brachii and the coracobrachialis muscles to the CP. In subtype IIb (frequency 5%), the coracobrachialis muscle was two-headed (the first head located under the second) and not connected to the short head of the biceps brachii; all heads were attached to a single CP. Type III (frequency 31%) was characterized by a two-headed coracobrachialis muscle, the first head originating from a bifurcated CP laterally to the short head of the biceps brachii and the second medially to this structure. Different variations connected with the mentioned structures could be problematic for surgeons during operations, so detailed knowledge of them could contribute to more efficient procedures.Item The carotid axis revisited(Scientific reports, 2021) Cobiella, R; Quinones, S; Konschake, Marko; Aragonés Maza, Paloma; Leon Vintró, Xavier; Vázquez Osorio, María Teresa; Sañudo Tejero, José Ramón; Maranillo Alcaide, EvaThe aim was to determine the variations in the level of origin of carotid bifurcation and diameters of the common, internal, and external carotid arteries which is clinically important for several interventional procedures. Therefore, 165 human embalmed corpses were dissected. The data collected were analyzed using the Chi square-test and the Pearson correlation test. The results of previous studies have been reviewed. In relation to the level of the carotid bifurcation, taking as a reference point the hyoid bone, the values ranged from 4 cm below the hyoid body to 2.5 cm above the body of the hyoid, being the average height—0.33 cm, with a standard deviation of 1.19 cm. The right carotid bifurcation was established at a higher level (x = − 0.19 cm.) than the left one (x = − 0.48 cm.) (p = 0.046). On the contrary, no significant gender differences could be observed. The arterial calibres of the common and internal carotid arteries were higher in male than female. In the internal carotid artery (X = 0.76 cm.), the left was greater than the right (X = 0.72 cm.) (P = 0.047). However, no differences in the distribution of the calibre of the external carotid artery were found neither by side nor gender. Variations in the level of bifurcation and calibres of carotid arteries are relevant for interventional radiology procedures and head and neck surgeries. Knowledge of these anatomical references might help clinicians in the interpretation of the carotid system.Item The anconeus muscle revisited: double innervation pattern and its clinical implications(Surgical and Radiologic Anatomy, 2021) Jiménez Díaz, Verónica; Aragonés Maza, Paloma; García Lamas, Lorena; Barco Laakso, Raúl; Quiñones, Sara; Konschake, Marko; Gemmell, Carolina; Sañudo Tejero, José Ramón; Cecilia López, DavidPurpose The aim of the present study is to describe in detail the morphology and innervation pattern of the anconeus muscle, bearing in mind clinical implications such as iatrogenic injuries during surgical elbow approaches. Methods A cadaveric study was performed; 56 elbows from 28 formalin-fixed cadavers belonging to the Anatomy Department of Universidad Complutense of Madrid were dissected. The triceps–anconeus nerve was located and dissected. A second innervation to the anconeus muscle from a branch of the posterior interosseous nerve (PIN) was occasionally detected. Taking the lateral epicondyle as a landmark, the entry points of both nerves in the muscle were referenced, the triceps–anconeus nerve was referenced at 0°, 30°, 45°, 70° and 90° of elbow flexion, and the PIN branch at 0°. Results Anconeus muscle was present in all specimens. The triceps–anconeus nerve was present in all of the dissected elbows. A branch from PIN to the anconeus muscle was present in 38 of the 54 elbows (70.4%). There were statistically significant differences in all measurements regarding the specimens’ gender, being higher for men. Conclusions There is evidence of a high frequency of a double innervation pattern for the anconeus muscle: the main branch of triceps–anconeus muscle depending on the radial nerve, which is liable to being damaged during posterior elbow approaches, and a secondary branch depending on the PIN. There are very few references to this finding in Anatomical literature and none with such a large sample size.
