title: Symphyseal separation, sacroiliac joint dislocation and transient lateral femoral cutaneous neuropathy associated with McRoberts' maneuver. A case report.
abstract: BACKGROUND
  McRoberts' maneuver is often used prophylactically with the onset of active maternal expulsive efforts or immediately before delivery of the fetus.
  
  
  METHODS
  A 31-year-old woman, gravida 1, para 0, at 39 + 2 weeks' gestational age, was continuously maintained in an exaggerated lithotomy position while actively pushing during the second stage of labor. Immediately following spontaneous vaginal delivery of a 3,598-g infant, the patient noted left gluteal pain and left anterior thigh dysesthesia. Orthopedic evaluation revealed a 5-cm symphyseal separation, sacroiliac joint dislocation and transient lateral femoral cutaneous neuropathy. The patient underwent closed reduction of the left hemipelvis, followed by open reduction and internal fixation of the symphysis pubis two weeks later after failing conservative treatment.
  
  
  CONCLUSIONS
  Although McRoberts' maneuver is generally safe, care should be exercised with use of excessive force or prolonged placement of the patient's legs in a hyperflexed position.
