Anatomical Correlation of Kandara with the Fibromusculoskeletal Structures of the Human Hand

Abstract

Background: Rachana Sharira (Ayurvedic anatomy), as codified by Acharya Sushruta, describes a class of cord-like fibrous structures termed Kandara — described as a rounded (Vritta) variety of Snayu and classified as an Upadhatu (secondary tissue product) of Rakta Dhatu (the blood tissue). Sixteen Kandara are enumerated across the body, of which four are specifically located in the Hasta (hand and forearm region), two on each side. Modern descriptive and clinical anatomy, by contrast, characterises the hand as a fibro-osseous and musculotendinous unit built around long flexor and extensor tendons, retinacula, pulley systems, and fascial septa.
Objective: This review attempts a structured correlation between the classical concept of Kandara and the fibromusculoskeletal architecture of the human hand as understood in contemporary gross anatomy, with a view to bridging Ayurvedic Sharira Rachana with evidence-based anatomical science.
Methods: Classical Ayurvedic compendia (Sushruta Samhita Sharirasthana, with supporting references from Ashtanga Sangraha, Ashtanga Hridaya, Bhavaprakasha and Sharangdhara Samhita) were reviewed alongside standard anatomical texts and peer-reviewed anatomical literature on the flexor and extensor apparatus of the hand and wrist.
Findings: The functional description of Kandara — cord-like, contractile-relaxable (Aakunchana–Prasarana), continuing distally toward the Nakha (nails), and structurally distinct from the broader, flatter Prithula Snayu and porous Sushira Snayu — corresponds closely with the long flexor and extensor tendons of the digits, their retinacular pulleys, and the fibrous digital sheaths of the modern hand.
Conclusion: Kandara of the Hasta Pradesha may be reasonably correlated with the flexor digitorum superficialis/profundus and extensor digitorum tendon complexes together with their stabilising retinacula, offering a physiologically coherent bridge between classical Ayurvedic terminology and modern hand anatomy, with relevance to the pathophysiology of Vata-predominant disorders such as Vishvachi and Vatakantaka.
