“…Four studies 15,25,28,30 consisting of 10 cohorts totaling 72 specimens were subjected to shear stress. Univariate analysis showed screws to have a significantly higher mean UFL (476.5 (430.5–522.5) N) than suture buttons (175.5 (63.5–287.5) N) (p < 0.001).…”

“…The eight included studies 15,18,25–30 represent 145 specimens within 17 different cohorts tested for biomechanical strength of Latarjet construct fixated with screws or suture buttons (Table 1). Cohorts testing Bristow procedure strength or using other fixation methods were excluded.…”

“…12 Additionally, variations in implants used have been described. 13–17 These variations include the use of suture buttons instead of the initially described screws. Some of the benefits of suture button fixation are ease of instrumentation arthroscopically and minimization of hardware complications.…”

“…21–24 Biomechanical studies have looked at the ultimate failure load (UFL) of Latarjet constructs and their modes of failure. 13,15–18,25–30 Some tout equivalency of suture buttons and screw fixation, 18,26 while others claim superiority of one technique over the other. 30 Differences in methodology including variations in screw design and size further complicate a comparison of available literature.…”

Background The Latarjet procedure reduces recurrent glenohumeral instability but has potential hardware and graft complications. The procedure has been modified to use various screw types as well as suture buttons. Biomechanical studies have evaluated the effect of these implants on construct strength. With varying results it is unclear whether there is an optimal implant to use. Methods We conducted a systematic review of human cadaveric biomechanical studies evaluating Latarjet ultimate failure load. Two independent reviewers screened articles and included them after full text review. Additional factors including implants used, graft orientation, cortices engaged, drill diameter, and screw characteristics were recorded. Meta-regression was performed on the 145 specimens from eight studies that met inclusion criteria. Results Screw fixation resulted in a 396.8 N (95% CI, 149.8–643.7) N higher ultimate failure load against shear stresses than suture buttons (p = 0.002). There were no differences between implants for ultimate failure load against tensile forces. Tensile strength was significantly affected by drill diameter with each millimeter of increase reducing the mean ultimate failure load by 127.4 N (95% CI, 41.2–213.6) N (p = 0.004). Conclusions These results suggest that using screw fixation and minimizing drill diameter can obtain the maximum ultimate failure load against both shear and tensile forces in a Latarjet construct.
