Introduction
Surgeons are increasingly using alternatives to traditional
screws for syndesmostic stabilization such as suture-button
devices. The clinical effectiveness of suture-button devices
to stabilize the distal tibia-fibula articulation with a
decreased incidence of iatrogenic syndesmotic malreduc-
tion has already been demonstrated.
17
Additionally, biome-
chanical cadaveric studies have compared such devices to
metal screws and have generally shown clinically equiva-
lent results when placed in an anatomic plane.
3,5,6,10,13
Despite this, the suture-button device may not be appropri-
ate for all injuries to the syndesmosis.
A fundamental principle in the operative management of
ankle fractures with associated syndesmotic injury is to first
restore fibular length/rotation and then correct syndesmotic
alignment. Several studies have demonstrated altered joint
contact pressures and kinematics when fibular length was
not restored.
2,8,9,14-16
This correction is most commonly
achieved by direct reduction and internal fixation at the
fracture site.
1
However, for many higher fibula fractures,
plate fixation at the fracture site is usually not performed
and length/rotation can be restored indirectly by syndes-
motic fixation alone.
7,11
Although a metal screw is rigid and
resists bending and torsional forces in a multidirectional
manner, a suture-button acts by resisting tension forces
between the 2 buttons with dramatically less inherent mate-
rial rigidity. Furthermore, although the inner diameter of a
metal screw is typically equal to or greater than the drill
tunnel used, suture-buttons do not fill the drill tunnel used
to pass the device. Therefore, unlike a metal screw, a suture-
button device is subject to translation within the drill tunnel.
Although multiple biomechanical cadaveric studies have
been performed, to our knowledge all relied on syndesmotic
disruption in the setting of a length-stable fibular model and
did not evaluate the implant’s ability to resist fibular
shortening.
3,5,6,10,13,17
As such, for potentially axially unstable fibula fractures
(ie, Weber C, Maisonneuve-type injuries with shortening)
the suture-button device may be suboptimal if used alone.
1
The purpose of this article is to highlight this potential tech-
nical limitation of suture-button devices and demonstrate a
novel, minimally invasive solution when encountered.
Case Description
Case 1
A 27-year-old male semiprofessional football player pre-
sented for evaluation of a left ankle fracture-dislocation after
suffering a twisting injury. He had presented to an outside
institution where closed reduction and casting of the injury
had been performed. Postreduction imaging obtained at our
center demonstrated a Weber C fibular fracture consistent
with an axially unstable Maisonneuve injury (Figure 1).
Case 2
A 20-year-old woman presented for evaluation of her left
ankle injury 2 days after suffering a twisting injury while
roller skating. Imaging demonstrated a Weber C fibula frac-
ture with medial clear space widening on stress view radio-
graph consistent with an unstable Maisonneuve injury
(Figure 2).
