Our goal was to describe the typical scintigraphic pattern of posterior tibial tendinitis.. Bone scintigraphs were reviewed to study the scintigraphic characteristics of posterior tibial tendinitis in nine patients with posterior tibial tendinitis related to generalized rheumatic disease and in eight patients with isolated posterior tibial tendinitis.. The scintigraphic pattern of posterior tibial tendinitis is elongated increased uptake in the blood flow and blood-pool phase along the anatomical course of the tibialis posterior tendon at the medial aspect of the ankle (malleolus region). Static images demonstrate increased focal abnormal uptake at the medial malleolus and in the navicular bone.. Bone scintigraphy depicts a characteristic pattern of posterior tibial tendinitis. It is useful for the early diagnosis of idiopathic- or rheumatic-related posterior tibial tendinitis.

We reviewed the medical records and technetium bone/joint scans of 160 children presenting to the inpatient Pediatric Rheumatology service over a 3-year period. When the scan result (normal versus abnormal) was considered for each patient as a whole, scan sensitivity and specificity were both approximately 75%. However, when each joint was considered individually, sensitivity decreased to 37%, while specificity rose to more than 95% when compared to clinical examination. Reasons for these variations and their clinical correlation are discussed. Overall, radionuclide bone/joint scanning was found to be very useful in the evaluation of monoarticular and nonrheumatic disorders, but it did not alter therapy in children with known connective tissue disorders or other polyarticular diseases.
