Anomalies of coronary venous system, the valve of the coronary sinus (Thebesian valve) and other cardiac malformations may make interventions through the coronary sinus difficult. These variants may pose a challenge in cannulating the coronary sinus for retrograde cardioplegia and for interventions performed through the coronary sinus by cardiac electrophysiologist/interventional cardiologist. Retrograde cardioplegia is an established method of myocardial protection with advantages, indications, and complications...

Our understanding of the processes of human development that occur during and just after implantation is still incomplete. The anatomical studies by Erich Blechschmidt (1904-1992) at the University of Göttingen demonstrate the uniqueness and beauty of the early stages of individual human development or ontogeny. The interpretations of human embryology by Blechschmidt offer a simple unifying hypothesis: metabolic and biomechanical events are repeated, and this can be described as an ontogenetic recapitulation...

The pertinent literature widely describes ultrasound-guided procedures targeting the retrocalcaneal bursa and the tendon tissue to manage insertional Achilles tendinopathy. Synovial bursae and cutaneous nerves of the superficial retrocalcaneal pad are often overlooked pain generators and are poorly considered by clinicians and surgeons. A layer-by-layer dissection of the superficial soft tissues in the retrocalcaneal region of two fresh frozen cadavers was matched with historical anatomical tables of the textbook Traite d'Anatomie Topographique Avec Applications Médico-Chirurgicales (1909 by Testut and Jacob)...

One of the major challenges for health science students is the rapid acquisition of a new vocabulary in anatomy comprising several hundred new words. Research has shown that vocabulary learning can be improved when students are directed to vocabulary strategies. This paper reported a study with a formative intervention design inspired by Vygotsky's method of double stimulation. In this design, the students were put in a structured situation that invited them to identify the challenges in learning anatomy and then provided them with active guidance and a range of anatomy vocabulary learning strategies that scaffolded them to work out a solution to the challenge and develop their individualized anatomy learning resources...

Division of the growing long bone into individual basic parts, that is, diaphysis, metaphysis, physes and epiphyses, has become generally accepted and used. However, the origin of these terms is almost unknown. Therefore, we have analyzed the literature in order to identify their sources. The terms epiphysis and apophysis have been used since the time of Hippokrates, although with different meanings. During the time of Galen, the term apophysis was used to describe all types of bone processes, and epiphyses denoted articular ends...

The two most common techniques to determine femoral tunnel placement during medial patellofemoral ligament (MPFL) reconstruction are radiographic and by palpation. Their intra/interobserver reliability is widely debated. Both techniques rely on identifying bony landmarks such as the medial epicondyle (ME) and adductor tubercle (AT) during surgery. During MPFL reconstructive surgery, the central longitudinal vessels (CLVs) are seen consistently. The aim of this study was to investigate the anatomic relationship of CLV to ME and AT and to determine if CLV might be used as a landmark during MPFL reconstruction...

The cervical spine manifests a wide shape variation. However, the traditional methods to evaluate the cervical spine curve were never tested against its actual shape. The study's main aim was to determine whether the shape classification of the cervical spine, based on traditional angular measurements, coincides with each other and with the shape captured by the 2D landmark-based geometric morphometric method. The study's second aim was to reveal the associations between the cervical spine shape and the demographic parameters, the head's position, and the spine's sagittal balance...

The plantar aponeurosis (PA) is an elastic longitudinal band that contributes to the generation of a propulsive force in the push-off phase during walking and running through the windlass mechanism. However, the dynamic behavior of the PA remains unclear owing to the lack of direct measurement of the strain it generates. Therefore, this study aimed to visualize and quantify the PA behavior during two distinct foot postures: (i) neutral posture and (ii) windlass posture with midtarsal joint plantarflexion and metatarsophalangeal joint dorsiflexion, using computed tomography scans...
