Osteoid osteoma of the hand and wrist.

Eighteen cases of osteoid osteoma of the hand and wrist were treated between 1985 and 1999. The diagnosis was confirmed pre-operatively with X-rays, bone scintigraphy, CT, and MRI, and all the diagnoses were later confirmed by histological examination. The authors highlight the difficulties in the diagnosis of the osteoid osteoma of the hand and wrist. An accurate clinical history and a high index of suspicion are required. Three phase bones scans are highly sensitive for osteoid osteoma and should be used in conjunction with CT examination to facilitate diagnosis and pre-operative planning. All the patients were treated surgically, by removal of the tumour, with complete resolution of all symptoms.
