@entity1 @entity6 @entity16 @entity1066 @entity1897 @entity158
BACKGROUND: The foot and ankle surgeon can see @entity1897 in the treatment of foot and ankle conditions. The purpose of this study was (1) to evaluate the demographics and presenting complaints of @entity1 diagnosed with @entity1897 during an examination by a foot and ankle surgeon and (2) to identify the type and frequency of subsequent diagnosis of medical causes of @entity16 . METHODS: This was a retrospective study of @entity1 diagnosed with @entity1897 in our practice between January 1997 and December 2008. Ninety-five @entity1 were identified, and demographic data, presenting complaints, and medical comorbidities were extracted from the medical record. Examination findings of decreased sensation to Semmes Weinstein 5.07 monofilament testing were documented, and electromyogram and nerve conduction study results were reviewed when available. Laboratory values were noted, as were neurologic evaluations performed to diagnose medical conditions associated with @entity1897 . RESULTS: The most common presentation was foot @entity158 , in 36 @entity1 (38%). Ninety-one @entity1 had Semmes Weinstein 5.07 monofilament testing, with loss of protective sensation reported in 75 of the 91 tested (82%). Only 30 of the 95 @entity1 had electromyogram and nerve conduction study results available, with a test positive for @entity1897 in 20 of the 30 tested. Thirty-two @entity1 were evaluated by a neurologist. A specific cause was identified in 12 of the 32 seen by a neurologist. Of the total group of 95 @entity1 , 31 @entity1 (33%) were diagnosed with a condition that may be associated with @entity1897 . CONCLUSIONS: Thirty-three percent of the @entity1 presenting to our clinic and given a diagnosis of @entity1897 were ultimately diagnosed with a medical cause of @entity16 -most commonly, @entity6 . For those @entity1 with @entity16 , a spectrum of disease was encountered, including @entity158 , @entity1066 , infection, and Charcot neuroarthropathy. LEVEL OF EVIDENCE: Level IV, retrospective case series.
