Abstract:

BACKGROUND: The second iliac crest screw technique was first proposed in 2007 as an alternative to traditional tibial screws. This technique has less tissue dissection and can be directly docked with the pedicle screw of the superior vertebral body without the need for a connecting rod, special pre-bending and additional connecting rods and holds deep entry points. It has been widely used in spinalpelvic fixation.

OBJECTIVE: To summarize new advances in the second iliac crest screw technique and provide new ideas for clinical complication prevention.
METHODS: WanFang, CNKI and PubMed databases were retrieved for related literature published from 1990 to 2018. The keywords were “the second iliac crest screw, iliac screws, complication, infection, loose screws, screw break, proximal junctional kyphosis, PJK, sacroiliac joint degeneration, screw protruding, incision split” in Chinese and English, respectively. The old and repeated views were excluded, and the eligible articles were included for review.
RESULTS AND CONCLUSION: Forty-six articles were included. (1) The second iliac crest screw is similar in biomechanical strength to iliac screws. (2) The incidence of complications such as loosening, rupture, wound infection, and symptomatic screw protrusion of the second iliac crest screw is significantly lower than that of the tibial screw. (3) The degeneration of the sacroiliac joint degeneration and pseudoarticular formation of borderline kyphosis is close to that of the tibial screw. Most of the screws with a rupture of the second iliac crest screw are concentrated at 8 mm or less, and the fracture position is mostly at the neck where the screw head and the nail body meet. In addition, the uninsertion of the S1 screw is also a risk factor for S2AI broken nails. (4) Implantation of S2AI cannot result in sacroiliac joint degeneration. (5) Choosing shorter, thicker screws for clinical placement of S2AI and proper reinforcement of the screw neck during production may help prevent S2AI fracture.
