The following case report shows the medical course of a sagittal ulnar splitting. The 29-year-old patient developed osteomyelitis of the right elbow joint in childhood. Subsequently, a pronounced ulnar advancement with painful movement restrictions in the wrist develops. Therefore, a sagittal ulnar split was performed and fixed with five bone screw grafts. Ten weeks after the procedure, the patient can return to his work as a high-voltage fitter without any complaints.
