Core Tip

Core tip: Allograft interbody spacers are commonly used in lumbar transforaminal lumbar interbody fusion procedures. A complication previously undocumented in the literature, we report on a fractured allograft interbody spacer that displaced into the neural foramen and resulted in impingement on the exiting nerve root that required revision. At 12 mo post-op, the patient was doing well with computed tomography scan confirming fusion and subsequent removal of the impinging fractured graft fragment. While presumably a rare occurrence, the authors review several technical points to avoid this complication.
