Intra-articular Synovial Ganglion of the Wrist.

Synovial ganglions, common soft tissue tumors of the hand and wrist, typically occur in the dorsal and volar aspects of the wrist, but intra-articular cases are rare. We present a case of a 27-year-old equestrian with persistent left wrist pain who was diagnosed with an intra-articular radiocarpal synovial ganglion after failed conservative management. Arthroscopic resection led to complete resolution of symptoms and functional recovery.

Altered potassium channel distribution and composition in myelinated axons suppresses hyperexcitability following injury.

Neuropathic pain following peripheral nerve injury is associated with hyperexcitability in damaged myelinated sensory axons, which begins to normalise over time. We investigated the composition and distribution of shaker-type-potassium channels (Kv1 channels) within the nodal complex of myelinated axons following injury. At the neuroma that forms after damage, expression of Kv1.
