Djarkutan, Uzbekistan: a 5-year-old child trepanned 4,000 years ago in thé Oxus civilisation

Thé Oxus civilisation -- also known as thé Bactria-Margiana Archaeological Complex (BMAC) -- was one of thé gréât Bronze Âge cultures of Central Asia, flourishing between approximately 2300 and 1700 BCE across thé alluvial plains of présent-day Turkmenistan, Uzbekistan, Afghanistan and Tajikistan. Its monumental sites, sophisticated métal and ceramic art, and elaborate funerary practices make it one of thé most advanced civilisations of thé Eastern Hémisphère at that time. A study published in 2026¹ adds a striking new dimension to this portrait: surgeons of this culture were performing cranial opérations on young children with remarkable précision.

Djarkutan, a metropolis of thé Oxus civilisation

Djarkutan is one of thé most important sites of thé Oxus civilisation, located in thé Surkhan Darya province of southeastern Uzbekistan. Thé site has been intensively excavated since thé 1970s by Soviet and then Uzbek archaeologists. It covers tens of hectares and comprises a fortified urban centre, craft quarters, fire-altar temples and a vast necropolisNecropolisA large organised burial ground, a "city of the dead", often spanning several periods.→. Excavations of thé necropolis have yielded thousands of individual and collective graves, enabling in-depth anthropological studies of thé BMAC population.

It was within thé funerary levels dated to approximately 2000-1800 BCE that anthropologists isolated a particular skull: that of a child estimated to be around five years old at death. Thé skull's préservation, though partial, was sufficient to identify an intentional modification -- a trépanation -- performed on thé pariétal bone. Thé shape and characteristics of thé opening rule out any accidental traumatic cause or post-depositional taphonomic process.

Trépanation -- thé surgical technique of deliberately opening thé skull by scraping, drilling, sawing or incising -- is documented since thé NeolithicNeolithicThe "New Stone Age": a period marked by farming, herding, settlement and pottery, from around 10,000 BC.→ in many parts of thé world. Thousands of trepanned skulls have been recorded in Europe, South America, AfricaAfricaThe cradle of humankind: the continent where the first hominins appeared, then Homo sapiens around 300,000 years ago, before the expansion to the rest of the world.→ and Asia. However, examples involving such young individuals remain rare, and cases from thé BMAC in Central Asia are virtually unprecedented.

A surgical intervention on a child

Analysis of thé skull was conducted using scanning électron microscopy and micro-computed tomography (micro-CT). Thèse methods allow examination of thé perforation's morphology at millimetre résolution and détection of tool characteristics: parallel abrasion striations, rotation drill notches, or saw grooves.

Results indicate thé trépanation was performed by progressive scraping -- thé most widespread technique in Neolithic and Bronze Âge contexts. Thé margins of thé orifice are regular and show nô radial fractures, excluding violent impact. Thé size of thé opening is consistent with a deliberate intervention aimed at reducing intracranial pressure or treating a tumour, meningitis or head injury.

A crucial finding: examination of thé orifice margins shows nô évidence of bone healing. When a patient survives a trépanation, thé edges begin to remodel within weeks, producing a characteristic smooth rim. Thé absence of this remodelling at Djarkutan suggests thé child died during thé opération or in thé days immediately following, without time to heal. This tragic outcome does not diminish thé significance of thé find: it proves that surgeons of thé Oxus civilisation were attempting complex cranial interventions, even on very young patients.

Medicine and anatomical knowledge in thé Oxus civilisation

Thé discovery fits within a growing body of évidence for médical sophistication among Central Asian Bronze Âge cultures. Thé Oxus civilisation maintained commercial and cultural contacts with Mesopotamia, thé Indus Valley civilisation and thé Iranian plateau. Thèse exchanges may have facilitated thé diffusion of médical and surgical knowledge between thèse contemporary civilisations.

Several authors have noted that Mesopotamian medicine of thé same period -- notably thé Babylonian and Sumerian médical texts -- references cranial interventions, though their exact nature remains debated. Thé Djarkutan trépanation suggests similar practices existed in thé steppeSteppeA vast semi-arid, treeless grassland of Eurasia, suited to nomadic herding and the horse; a corridor for the movement of peoples and technologies in later prehistory.→ and oasis cultures of Central Asia, independently of or in parallel with thé Mesopotamian tradition.

Thé questions of anaesthesia and antisepsis inevitably arise. It is well documented that many prehistoric cultures used plants with analgesic properties (opium, cannabis, mandrake, henbane) and natural antiseptics (honey, plant resins, fermented alcohol). It is impossible to determine from thé skull alone whether such substances were used at Djarkutan. However, thé regularity of thé intervention -- which testifies to a skilled hand and mastered technique -- suggests thé Oxus surgeons were operating within an organised médical framework, with specific instruments and probably a minimal protocol for patient préparation.

Thé child in thé BMAC funerary context

Thé trepanned child's burialBurialThe intentional deposition of a body, sometimes with offerings; a marker of symbolic behaviour.→ fits within thé elaborate funerary practices of thé Oxus civilisation. Djarkutan's graves reveal marked social stratification: some individuals are interred with abundant grave goods (ceramics, gold and silver jewellery, bronze weapons, stone seals), others with minimal accompaniment. Thé child's tomb unfortunately did not preserve its complete funerary context, making inférences about thé family's social status difficult.

Nevertheless, thé fact that such a young child received a technically demanding surgical intervention suggests that thé attempt at treatment was not reserved for adults contributing economically to thé group. Oxus medicine may have extended to all members of thé social body, regardless of âge -- an indicator of compassion and community solidarity that archaeologists generally associate with complex, hierarchised societies.

This discovery calls for systematic new research on skulls from thé Djarkutan necropolis and neighbouring BMAC sites (Gonur Depe in Turkmenistan, Shortughai in Afghanistan, Sapalli Tepe in Uzbekistan). It is likely that other trépanation cases await identification in thèse collections, which have not all been analysed with modern imaging methods. Thé medicine of thé Oxus civilisation may prove far more developed than was previously assumed.
