http://medical-dictionary.thefreedictionary.com/poker spine

Ankylosing Spondylitis is an inflammatory disease of unknown origin, first affecting the spine and adjacent structures, and commonly progressing to eventual fusion (ankylosis) of the involved joints.

In extreme cases, the patient develops a forward flexion of the spine, called a "poker spine" or "bamboo spine."

În textul meu apare enumerarea:
Marie-Strümpell's Disease, Rheumatoid Ankylosing Spondylitis, Poker Spine
Am tradus: Artrită Marie-Strümpell, spondilartrită anchilozantă, ... mai rămâne "poker spine" - dacă sunt sinonime perfecte, pot să renunţ la termen.

Mulţumesc anticipat.
