[Between hallux rigidus arthrosis and gout is no causal relationship].

The following assertion - continuously being alleged - is examined: Hallux rigidus arthrosis is said to occur in patients suffering from gout more frequently than average, and it should be valued as a symptom of chronic gout. Results of our own findings are as follows: 1. Hallux rigidus arthrosis becomes manifest in general on the right side or bilaterally, respectively; on the left side, however, it occurs rarely in an isolated state. 2. In patients with hallux rigidus arthrosis hyperuricaemia, gout, and obesity are seen more frequently than in adults of the normal population - these three diseases often are combined with static mutations in the region of the lower extremities. 3. No criteria can be stated as to causal relationship between hyperuricaemia (or gout) and hallux rigidus arthrosis. Obesity has to be considered a connecting link between both of them, and it is accelerating their genesis. 4. Hallux rigidus arthrosis represents - same as the arthrosis of Heberden - the more frequent possibility for confusing it with gout.
