Delayed or nonunion of the hamulus ossis hamati is a rare condition, typically managed surgically by either fixation or excision. This case report highlights the successful treatment of a 30 year-old dentist with a nonunion of the basis of the hamulus type Milch 1-3 in his dominant right hand. Bone stimulation was achieved with a combination of focused electromagnetic extracorporeal shock wave therapy (ESWT, Storz Ultra) and extracorporeal magnetotransduction therapy (EMTT, Storz Magnetolith) with five sessions within 2,5 weeks. Clinical and radiological improvement was observed, within six weeks after the first treatment, highlighting the potential of ESWT/EMTT as superior bone stimulators and a conservative alternative to surgery in nonunion situations of the hand.
