On Oct. 16, 2024, a researchers at Copenhagen University Hospital reported in a medical case report that a breakdancer who’d been performing for 19 years was treated for “headspin hole”, a condition also known as “breakdancer bulge” that’s unique to breakdancers.

The ‘bulge’ resulted from a cone shaped mass developing on top of the scalp after repetitive head-spinning. Additional symptoms can include hair loss and sometimes pain around the lump. Approximately 30 percent of breakdancers reported hair loss and inflammation of their scalp from head-spinning. The study results were published in BMJ Journals.
