Accidental Durotomy in Minimally Invasive Transforaminal Lumbar Interbody Fusion: Frequency, Risk Factors, and Management

Figure 2

Wound closure. Subcutaneous sutures and skin adhesive were used for closing the wound. Placement of a drain is not necessary. The more lateral incisions (arrows) were used for minimally invasive implantation of screws, decompression of the spinal canal, and transforaminal insertion of the intervertebral cage (see also Figure 1). The stab incisions (asterisk) were used for minimally invasive rod insertion.
