Abstract：Objective To explore the causes of bone cement leakage after percutaneous kyphoplasty (PKP),thus preventing misdiagnosis.Methods We conducted a retrospective analysis on a medical dispute case regarding neurological dysfunction of left lower limb caused by bone cement leakage after conducting PKP for osteoporotic vertebral body compression fractures (OVCFs).Results This patient presented with pain and swelling of waist,accompanied with restricted movement for 3 h due to falls.The patient was diagnosed as having fresh fracture in first lumbar vertebra and old fracture in second lumbar vertebra.The PKP surgery was conducted on the third day of hospitalization.At 9 days after surgery,left lower limb numbness was noted,which was ameliorated with neurotrophic treatment,and the patient was then discharged home.The patient was rehospitalized 48 days after surgery because of left lower limb numbness with activity restriction,and underwent laminectomy.Bone cement was intraoperatively confirmed to leak into spinal canal,leading to deformation of dural sac.This caused activity restriction in left lower limb,which induced medical dispute.Conclusion Prior to PKP surgery,it is of great significance to have a thorough understanding and analysis of pathogenic conditions of patients.After surgery,it is necessary to timely evaluate distribution of vertebra bone cement and perform surgical examination if necessary to prevent or reduce neurological damage.
