Koski JM et al. (2006) Power Doppler ultrasonography and synovitis: correlating ultrasound imaging with histopathological findings and evaluating the performance of ultrasound equipments.

Our first pilot study on this matter (2005) stated that volar synovitis is more correlated to clinical examination than dorsal one. [14] Several studies have addressed volar synovitis so far.

Studies of patients with PMR and giant-cell arteritis indicate that PMR could be a vasculitis limited to the subclavian or axillary arteries, or a synovitis or perisynovitis of the shoulders and hips.

The prevalence of hip dysplasia and hip dislocation is 2 to 5%—a thousand times that of all other named (1) pediatric hip disorders, with the exception of transient synovitis (0.076%).
