title: Foot pain: specific indications for scintigraphy.
abstract: Bone scintigraphy is requested as part of the investigation of foot pain, but its contribution to clinical management has not been comprehensively documented. Previously published data are limited; the most comprehensive series identified scintigraphic abnormalities in patients with primarily orthopaedic problems and a control group was not included (Maurice HD et al. J Bone Joint Surg 1987;69B:448 52). The aim of this study was to evaluate whether bone scintigraphy may be useful in different clinical circumstances indicated by referral request details. Regions of scintigraphic abnormality were scored and compared with clinical details drawn from case notes of 60 patients with foot pain. The commonest clinical indications for scans were: confirmation of the clinical suspicion of plantar fasciitis, documentation of the extent of inflammatory arthritis and location of focal pathology. A group of 30 asymptomatic, age- and sex-matched controls were also studied. In 14 out of 19 symptomatic feet in the plantar fasciitis group, focal uptake at the medial calcaneal tubercle was present, confirming the diagnosis. In patients with non-specific, diffuse foot pain, the bone scan identified focal abnormalities in 11 out of 14 cases, thus directing the clinician to the site of pathology. Scintigraphy also proved useful in mapping local inflammatory disease. Technetium-99m methylene diphosphonate image abnormalities occurred in the control group most commonly in the midfoot (16 regions in 13 subjects) and first metatarsophalangeal joint (19 regions in 14 subjects).
