Flexor Tenosynovitis in Rheumatoid Arthritis

A 61-year-old woman with rheumatoid arthritis had morning stiffness and restricted flexion of the fingers (normally the fingertips touch the palm when the fingers are flexed while the MCP joints are held straight). The injection site is marked and then the skin cleansed. Before injecting, an observation is made that flexing the finger moves the needle - the needle is inside the tendon. The needle is pulled slighly backwards and the medication is injected next to the tendon, without resistance. Using a small needle, a mixture of methylprednisolone and an anaesthetic agent is injected into the flexor tendon sheath. The puncture site is covered with a self-adhesive sterile dressing, and it should not be allowed to get wet on the puncture day.
