The Scaphoid Staple: A Systematic Review

Abstract

For all indications, the scaphoid staple has a high union rate and a low complication rate. In the authors' experience, the procedure is fast, not technically challenging, and may be considered for primary fracture, delayed union, nonunion, and avascular necrosis of the scaphoid.

Comparison of Shape Memory Staple and Gelled Platelet-Rich Plasma versus Shape Memory Staple alone for the Treatment of Waist Scaphoid Nonunion: A Single-Center Experience

“… 21 22 SNUs fixed with SMS are stable and can therefore be compared with undisplaced fractures. 23 Hence, we decided to perform the immobilization for only 4 weeks after surgery to avoid immobilization overtreatment. In the literature, there is no unique way to define and characterize SNUs.…”

Salvage Fixation With a Single Nitinol Compression Staple for a Lateralized Fibular Tunnel in Posterolateral Corner Reconstruction of the Knee

“…10 The pseudo-elastic properties of the staple allow for sustained compression and have been shown to be superior to traditional fixation methods in fractures of the scaphoid and midfoot. 7,11 Additionally, the lowprofile nature of the staple minimizes contact and subsequent irritation to the peroneal nerve, even with full knee extension. Compared to other salvage techniques for a lateralized fibular head tunnel, including use of suture anchors and redrilling, the described method using a compression staple is mechanically superior and results in a higher ultimate tensile strength compared to controls in response to uniaxial tension testing (unpublished data).…”

Controversies and best practices for acute scaphoid fracture management

“…Dunn et al. (2017) recently published the first systematic review of scaphoid staples and reported union rates for acute waist fractures ( n = 77) to be 100% and return to work at 9.8 weeks.…”

“…In addition, Bain et al (2015) showed dorsal plating on the tension side of the fracture to be mechanically more sound; however, no clinical outcome studies comparing plate and screw fixation have been published yet. Dunn et al (2017) recently published the first systematic review of scaphoid staples and reported union rates for acute waist fractures (n = 77) to be 100% and return to work at 9.8 weeks. However, most studies on staples report their use in scaphoid nonunions, making generalizations for acute fractures difficult (Korkala and Antti-Poika, 1989;Korkala et al, 1992;Rocchi et al, 2005;Winkel and Schlageter, 2009).…”
