Its occurrence after endoscopic surgery has rarely been reported in the literature so far. This is a case report of a 52-year-old male occurring PBGM into the thecal sac in the 8th days after an endoscopic lumbar interbody fusion (ELIF), which can make surgeons more minded with such serious rare complication after BGM.<h4>Case presentation</h4>A 52-year-old male patient, underwent a L4-5 ELIF, presented with an acute radiculopathy on right leg and urinary incontinence in the 8^th postoperative day. An emergency lumbar Computed Tomography(CT scan) and Magnetic Resonance Imaging (MRI) demonstrated bone graft migration into the thecal sac at the L4-5 level, and shifting dBMC musculoskeletal disordersPostoperative bone graft migration into the thecal sac and shifting down to the lower level after an endoscopic lumbar interbody fusion: a case report.PMC9948321No.2022-YF05-02035-SNFan XXie YZhou QWang YFeng CYu YfalsePostoperative bone graft migration into the thecal sac and shifting down to the lower level after an endoscopic lumbar interbody fusion: a case report.<h4>Background</h4>Postoperative bone graft migration (PBGM) is a fairly rare spinal postoperative complication.
