Aims. The ideal management of acute syndesmotic injuries in elite athletes is controversial. Among several treatment methods used to stabilize the syndesmosis and facilitate healing of the ligaments, the use of suture tape (InternalBrace) has previously been described. The purpose of this study was to analyze the functional outcome, including American Orthopaedic Foot & Ankle Society (AOFAS) scores, knee-to-wall measurements, and the time to return to play in days, of unstable syndesmotic injuries treated with the use of the InternalBrace in elite athletes. Methods. Data on a consecutive group of elite athletes who underwent isolated reconstruction of the anterior inferior tibiofibular ligament using the InternalBrace were collected prospectively. Our patient group consisted of 19 elite male athletes with a mean age of 24.5 years (17 to 52). Isolated injuries were seen in 12 patients while associated injuries were found in seven patients (fibular
The morphology of medial malleolar fracture is highly variable and difficult to characterize without 3D reconstruction. There is also no universally accepeted classification system. Thus, we aimed to characterize fracture patterns of the medial malleolus and propose a classification scheme based on 3D CT reconstruction. We retrospectively reviewed 537 consecutive cases of ankle fractures involving the medial malleolus treated in our institution. 3D fracture maps were produced by superimposing all the fracture lines onto a standard template. We sliced fracture fragments and the standard template based on selected sagittal and coronal planes to create 2D fracture maps, where angles α and β were measured. Angles α and β were defined as the acute angles formed by the fracture line and the horizontal line on the selected planes.Aims
Methods
Stable fractures of the ankle can be safely treated
non-operatively. It is also gradually being recognised that the integrity
of the ‘medial column’ is essential for the stability of the fracture.
It is generally thought that bi- and tri-malleolar fractures are
unstable, as are pronation external rotation injuries resulting
in an isolated high fibular fracture (Weber type-C), where the deltoid
ligament is damaged or the
The AO Foundation advocates the use of partially
threaded lag screws in the fixation of fractures of the medial malleolus.
However, their threads often bypass the radiodense physeal scar
of the distal tibia, possibly failing to obtain more secure purchase
and better compression of the fracture. We therefore hypothesised that the partially threaded screws
commonly used to fix a medial malleolar fracture often provide suboptimal
compression as a result of bypassing the physeal scar, and proposed
that better compression of the fracture may be achieved with shorter
partially threaded screws or fully threaded screws whose threads
engage the physeal scar. We analysed compression at the fracture site in human cadaver
medial malleoli treated with either 30 mm or 45 mm long partially
threaded screws or 45 mm fully threaded screws. The median compression
at the fracture site achieved with 30 mm partially threaded screws
(0.95 kg/cm2 (interquartile range (IQR) 0.8 to 1.2) and
45 mm fully threaded screws
(1.0 kg/cm2 (IQR 0.7 to 2.8)) was significantly higher
than that achieved with 45 mm partially threaded screws (0.6 kg/cm2 (IQR
0.2 to 0.9)) (p = 0.04 and p <
0.001, respectively). The fully
threaded screws and the 30mm partially threaded screws were seen
to engage the physeal scar under an image intensifier in each case. The results support the use of 30 mm partially threaded or 45
mm fully threaded screws that engage the physeal scar rather than
longer partially threaded screws that do not. A
45 mm fully threaded screw may in practice offer additional benefit
over 30 mm partially threaded screws in increasing the thread count
in the denser paraphyseal region. Cite this article:
