High-resolution MRI assessment of dactylitis in psoriatic arthritis shows flexor tendon pulley and sheath-related enthesitis

OBJECTIVE Dactylitis is a hallmark of psoriatic arthritis (PsA) where flexor tenosynovitis is common. This study explored the microanatomical basis of dactylitis using high-resolution MRI (hrMRI) to visualise the small entheses around the digits. METHODS Twelve patients with psoriatic dactylitis (4 fingers, 8 toes), and 10 healthy volunteers (6 fingers, 4 toes) had hrMRI of the digits using a...

Ankylosing enthesitis, dactylitis, and onychoperiostitis in male DBA/1 mice: a model of psoriatic arthritis.

OBJECTIVES To further characterise spontaneous arthritis in aging male DBA/1 mice as a model of spondyloarthropathy and psoriatic arthritis with particular attention to signs of inflammation and nail involvement. MATERIALS AND METHODS Aging male DBA/1 mice from different litters were caged together (4-6 mice per cage) at the age of 12 weeks, checked twice a week for signs of arthritis, and ki...

Flexor tendon pulley injury in a bowler.

Closed traumatic flexor injuries of the hand involving the pulley mechanism are a relatively common injury seen in rock climbers but are very rare in nonclimbers, including bowlers. The injury was first described in 1990. Since then, several studies have shed more light on the diagnostic and therapeutic considerations. Early diagnosis of pulley injuries is crucial since delayed diagnosis can le...
