title: Posterior tibial neuropathy from ruptured Baker's cyst.
abstract: OBJECTIVE
  To increase awareness of entrapment neuropathy caused by rupture of Baker's cyst.
  
  
  METHODS
  A patient with psoriatic arthritis, ruptured Baker's cyst, and entrapment neuropathy is reported and the literature on this complication is reviewed.
  
  
  RESULTS
  Nerve entrapment caused by rupture of Baker's cyst is rare. Neurological examination and demonstration of Baker's cyst by Color Doppler Duplex Ultrasound (CDDU) help in making the diagnosis. Nerve Conduction Study (NCS) may confirm the diagnosis of posterior tibial nerve entrapment.
  
  
  CONCLUSIONS
  Peripheral nerve entrapment should be considered in patients with Baker's cysts and loss of sensation along the plantar aspect of the foot or other neurological symptoms or findings.
