“…The incidence of the accessory navicular bone in the current study fits into the mentioned range. An overrepresentation of accessory navicular bone in patients with tibialis posterior tendon insufficiency can be noticed [34]. We observed no statistically significant differences regarding connections in patients with and without the accessory navicular bone, indicating a separate developmental origin [36].…”

The Flexor Retinaculum Connects the Surrounding Structures into the Medial Ankle Complex

et al. 2020

This study aimed to prove the hypothesis that the medial structures of the ankle are interconnected through the flexor retinaculum’s projections. We conducted a retrospective re-evaluation of 132 MRI examinations of the ankle joint from 57 females and 75 males with an age range of 18–65 and a mean age of 35 years. The correlation between the presence of connections between the flexor retinaculum and the deltoid ligament, the spring ligament, the inferior extensor retinaculum, the paratenon, the fibulotalocalcaneal ligament, the fascia covering the abductor hallucis, and the flexor fibrous sheath were studied. The most common connections of the flexor retinaculum were to the deltoid ligament (97%), the fibulotalocalcaneal ligament (84.1%), and the flexor fibrous sheath (83.3%). Interconnection between the flexor retinaculum and the deltoid ligament correlated with the presence of connections between the flexor retinaculum and the inferior extensor retinaculum, the paratenon, and the spring ligament. Side difference was noticed in connections to the flexor fibrous sheath, the deltoid ligament, the fascia on the abductor hallucis, and the paratenon (p < 0.05). The flexor retinaculum formed a more complex anatomical unit with adjacent structures.

Anatomical variation in the ankle and foot: from incidental finding to inductor of pathology. Part II: midfooot and forefoot

et al. 2019

View full text Add to dashboard Cite

Accessory anatomical structures in the ankle and foot usually represent incidental imaging findings; however, they may also eventually represent a source of pathology, such as painful syndromes, degenerative changes, be the subject of overuse and trauma, or appear as masses and cause compression syndromes or impingement. This review aims to describe and illustrate the imaging findings related to the presence of accessory ossicles and muscles in the midfoot and forefoot through different techniques, with special attention on those variants that associate factors of clinical relevance or that would trigger challenges in the differential diagnosis.

“…Anatomical variation is a normal presentation of body structure with morphological features different from those described in the literature. It involves many types and forms of variations, including muscle structure, attachments, and innervation, ligament attachments and morphology, blood vessel branching, nerve patterns and positions, and bone morphology and accessory bones [1][2][3][4][5][6][7]. It has been found that some of these anatomical variations are closely related to ethnic groups [8].…”

Literature Review of Anatomical Variations: Clinical Significance, Identification Approach, and Teaching Strategies

This article is a comprehensive literature review on anatomical variations, shedding some light on their clinical significance, identification approaches, and teaching strategies. Anatomical variation is a normal presentation of body structure with morphological features different from those that have been classically described in several anatomy textbooks. Under normal circumstances, it has no impact on the function of the structure. However, it may influence different aspects of clinical practice. As a result, accurate knowledge of common anatomical variations in the treated area may improve clinical practice outcomes. On the other hand, anatomical variations are usually identified during routine dissection and clinical practice, including preoperative imaging and surgical procedures. Additionally, scientific research, such as observational studies using cadaveric dissection, medical images, and evidence-based anatomy, are effective approaches to identify anatomical variations. With regard to the teaching of anatomical variations, cadaveric dissection is the most commonly used and recommended learning tool for teaching anatomy and relevant variations in medical schools. However, the literature emphasizes introducing anatomical variations in the clinical phase of medical curricula and postgraduate training of surgical and radiological programs. The current study suggests creating a registry of anatomical variations encountered during practice that may enhance best care and prevent any confusion about those variations. In addition, there is a need to conduct more educational studies to research the best learning strategies for teaching and assessing anatomical variations in the medical curricula.
