CT scan (with and without contrast) or MRI scan. CT scan may reveal bone erosion and evidence of rim enhancing abscess formation. There may be intracranial involvement, eg fluid collection and CT/MRI may also help in this.
Admission with removal of the infected bone and prolonged intravenous antibiotics (eg for six weeks). Antibiotics are usually of the penicillin group, eg high dose IV benzylpenicillin for 3 weeks followed by 3 weeks of oral amoxicillin. However, all cases should be discussed with the local microbiologist and antibiotics should be altered once sensitivities are known.
Percivall Pott (1714-1788) was a London surgeon (St. Bartholomew's Hospital) who also gives his name to Pott's disease of the spine (spinal tuberculosis - scrofula), and to Pott's fracture (fracture dislocation of the ankle). He was first to describe an industrially acquired disease: cancer of the scrotum in chimney sweeps.
