title: Meralgia paresthetica is related to degenerative pubic symphysis.
abstract: OBJECTIVE
  To investigate the relationship between meralgia paresthetica, a mononeuropathy of the lateral femoral cutaneous nerve that often starts in middle age, and radiological degeneration of the pubic symphysis.
  
  
  METHODS
  A case-control study of patients aged 40 years and older with meralgia paresthetica who underwent surgical release of the lateral femoral cutaneous nerve; cases were included only when a pelvic radiograph was available. The control group was from a population study including persons aged 55 years and older and was matched to cases (4 controls per case) for sex and age as far as possible. We checked patient records from general practice to ensure control subjects had no symptoms of meralgia paresthetica during the previous 10 years. Radiological degeneration of the pubic symphysis was defined as present when 2 of 3 independent observers noted degeneration on the radiograph.
  
  
  RESULTS
  Mantel-Haenszel procedure (stratified for age group and radiological osteoarthritis of the hip) showed a positive relationship (p = 0.004, OR = 4.38) between radiological degenerative pubic symphysis and meralgia paresthetica. In a separate analysis limited to men we also found this positive relationship.
  
  
  CONCLUSIONS
  This study confirmed a positive relationship between radiological degeneration of the pubic symphysis and meralgia paresthetica.
