Tabes dorsalis

Definition and stakes

A system of practical medicine… (1886)

The discovery of no single symptom of tabes dorsalis marks so important an epoch in its study as Westphal's observation that the knee-phenomenon is usually destroyed in it. Had this symptom not been detected, so Tuczek admits, ergotin tabes would have eluded recognition.79 It was claimed by a majority of neurologists at first that this jerk is always abolished in tabes, but it is now recognized that there are exceptions, as is shown by cases of Hirt,80 Westphal, and others, not to mention some well-established cases of its return during the progress of the disease.

Harry C. Solomon Neurosyphilis

TABETIC NEUROSYPHILIS (“tabes dorsalis”) is often quite ATYPICAL clinically and may even show no single symptom warranting the old clinical name “locomotor ataxia.”
Case 30. Stephen Green is a case of Tabes Dorsalis with active knee-jerks and without locomotor or muscle-sense disorder. When observed at the age of 45, it appeared that there were but two complaints: lack of control of the vesical sphincter and shooting pains in the legs. It appeared that the urinary disorder dated back ten years, when there had been difficulty in passing the urine.

Alexander Miles Manual of Surgery Volume First…

The occurrence of joint lesions in locomotor ataxia (tabes dorsalis) was first described by Charcot in 1868—hence the term “Charcot's disease” applied to them. Although they usually develop in the ataxic stage, one or more years after the initial spinal symptoms, they may appear before there is any evidence of tabes. The onset is frequently determined by some injury. The joints of the lower extremity are most commonly affected, and the disease is bilateral in a considerable proportion of cases—both knees or both hips, for instance, being implicated.
