PURPOSE: Single-use surgical instruments were recently introduced to improve OR efficiency and reduce @entity281 risks. This study aimed to investigate clinical results 1 year after instrumented lumbar fusion, with the aid of single-use surgical instruments, with particular attention to @entity281 and @entity717 Index (ODI). METHOD: This prospective bi-centric study included 21 @entity1 and 28 @entity1 , aged 61.6    12.8 years, that underwent short instrumented lumbar fusion for @entity179 , @entity850 , or degenerative spondylolisthesis. All @entity1 underwent posterior or transforaminal lumbar interbody fusion, using the SteriSpine    PS Pedicle Screw System, available in multiple traceable sterile kits. RESULTS: Instrumented fusion was performed at one level in 31, two levels in 11, three levels in 5, and four levels in 2 @entity1 . The mean follow-up was 16.4    2.1 months, during which the ODI improved by 20 or more points in 28 @entity1 (57 %), improved by less than 20 points in 17 @entity1 (35 %), and remained unchanged or worsened in 4 @entity1 (8 %). Only one @entity281 (2 %) was observed in a 60-year-old @entity1 with previous spine surgery and two additional risk factors ( @entity6 and BMI 38). Compared to an older series, using reusable instrumentation, performed by the same team for the same indications, the clinical outcomes were similar but the @entity281 rate was 6 %. DISCUSSION: Single-use instrumentation could reduce the incidence of surgical site infections following lumbar fusion to acceptable levels as in hip and knee arthroplasties. The preservation of screws and rods in sterile packs until ready for insertion reduces their exposure to air-borne bacteria in the OR and eliminates their contamination through repetitive hospital sterilization. The short operation time and minimal @entity190 achieved could also contribute to the reduction in @entity281 risks. LEVEL OF EVIDENCE: Level II, prospective randomized bi-centric study.

Single-use instrumentation in posterior lumbar fusion could decrease incidence of XXXX : a prospective bi-centric study.
