Abstract

Meticulous attention to wound closure in posterior lumbar spine surgery is an important principle in reducing surgical site infections. We detail standardized wound closure used for posterior lumbar spine surgery at a tertiary care referral center and illustrate this as a step-by-step cadaveric dissection. The lumbar spine of a cadaveric specimen (male, 73 years at death) was used for dissection. Standardizing wound closure in posterior lumbar spine surgery may help limit wound complications and infection. Some key points of our technique, as demonstrated on a cadaveric specimen, include separating fascial compartments, avoiding suture abscesses, and creating a tension-free wound.

Using a #10 scalpel blade and Cobb elevator to dissect the paraspinal musculature in a subperiosteal manner from the spinous processes and laminae

Figure 5

We preserved the supraspinous and interspinous ligaments during the dissection. We took the dissection up to the facet capsules without disrupting the facets

We then proceeded with wound closure, first using 0 vicryl suture to tightly reapproximate the fascial layer using a simple interrupted technique

Figure 9

We placed sutures in approximately 1 cm increments and tied four square knots to lock each suture down

Figure 10

We then utilized 2-0 vicryl suture in an inverted manner to close the dermal layer with buried knots, avoiding entry into the epidermal layer

Figure 11

We spaced each of these sutures in 1-cm increments and tied four square knots

We then utilized 3-0 nylon suture in a simple interrupted fashion to reapproximate the skin

The sutures were placed in 1-cm increments
