#1
Harm Hoekstra, Wouter Rosseels, Stefan Rammelt, Stefaan Nijs
The treatment of fractures of the posterior pilon is a timely issue. Restoration of the integrity of the incisura fibularis and subsequent anatomic reduction of the fibula are essential for reconstruction of the ankle mortise after trauma, and syndesmotic stability. Inappropriate treatment ultimately will lead to a poor functional outcome and quality of life. Open reduction and direct internal fixation through a posterolateral or posteromedial approach are increasingly preferred over indirect reduction and anteroposterior screw fixation...

PURPOSE: To date, there is a paucity of literature on syndesmotic reconstruction techniques that restore both anatomic stability and physiologic syndesmotic biomechanics. In this cadaveric study, (1) a novel syndesmotic reconstruction surgical technique using autogenous peroneus brevis tendon was described and (2) the biomechanical properties of the reconstruction was investigated. METHODS: Ten fresh-frozen lower extremities were used in this study. Reconstruction of the anterior and posterior, as well as the interosseous tibiofibular ligaments was performed with a halved peroneus brevis tendon...

BACKGROUND: Syndesmotic injuries can be associated with poor patient outcomes and posttraumatic ankle arthritis, particularly in the case of malreduction. However, ankle joint contact mechanics following a syndesmotic injury and reduction remains poorly understood. The purpose of this study was to characterize the effects of a syndesmotic injury and reduction techniques on ankle joint contact mechanics in a biomechanical model. METHODS: Ten cadaveric whole lower leg specimens with undisturbed proximal tibiofibular joints were prepared and tested in this study...

H Zwipp
About 90 % of all cases of painful posttraumatic ankle arthritis can be very successfully treated with a minor invasive ankle arthrodesis technique by using a small anterior approach and a fixation with four 6. 5 mm screws of which the posteromedial and transfibular one are inserted percutaneously. The results with this standardized procedure have been reported previously as excellent and good in a mid-term run of 6 years (34). This technique leads to a high union rate of 99% (92 of 93) with rapid bone healing within 8 ± 2 weeks, it causes a low minor complication rate of 8 % and enables a significant increase of the AOFAS ankle/hindfoot score (17) from 36 preoperatively to 85 postoperatively as well as a midtarsal movement of 24° ± 16°...

PURPOSE: Malalignment of syndesmosis is generally associated with a poor outcome, yet occurs at a high rate in malleolar ankle fractures. In this study, we examine whether malreduction of syndesmosis injury associated with malleolar ankle fracture can be avoided using Weber's three indexes in the mortise view. MATERIALS AND METHODS: Of 156 patients with malleolar ankle fracture who underwent surgery from December 2012 to March 2016 at two medical facilities, 24 patients who received syndesmotic screw fixation were included in the study...

Normal syndesmosis anatomy and alignment are essential to ankle function. Although injuries to the syndesmosis are common with ankle injuries, accurate diagnosis and reduction continue to be a challenge. Late reconstruction for syndesmosis is reviewed. A surgical technique for late reconstruction is outlined in detail.

PURPOSE: To investigate whether arthroscopy or stress radiography can identify instability resulting from single-ligament injury of the ankle syndesmosis and to determine whether either modality is capable of differentiating between various levels of ligament injury. METHODS: Syndesmotic/deltoid ligament sectioning was performed in 10 cadaver legs. Arthroscopic evaluation and fluoroscopic stress testing were completed after each sectioning. In group 1 (n = 5), sectioning began with anteroinferior tibiofibular ligament (AITFL), then interosseous membrane (IOM), posteroinferior tibiofibular ligament (PITFL), and deltoid...

BACKGROUND: Inadequate ankle syndesmotic reduction is a common and important cause of poor outcome after surgery. It is not clear what magnitude or planes of displacement impact most. Many computerised tomography (CT) measurement techniques rely on landmarks that are difficult to reproduce, and none measure all types of mal-positioning in a single protocol. The purpose of this study was to design and validate a protocol for measuring the distal tibio-fibular relationship. METHODS: We devised a method for measuring fibular diastasis, antero-posterior translation (APT) and fibular length on CT images...

BACKGROUND: Post-traumatic osteoarthritis (PTOA) is responsible for the majority of cases of ankle arthritis. While acute and end-stage intra-articular inflammation has previously been described, the state of the joint between fracture healing and end-stage PTOA remains undefined. This study characterized synovial fluid (SF) composition of ankles after bone healing of an intra-articular fracture to identify factors that may contribute to the development of PTOA. METHODS: Of an original 21 patients whose SF was characterized acutely following intra-articular ankle fractures, 7 returned for planned hardware (syndesmotic screw) removal after bone healing (approximately 6 months) and consented to a second bilateral SF collection...

BACKGROUND: Ankle fractures associated with syndesmotic injury have a poorer prognosis than those without such an injury. Anatomic reduction of the distal tibiofibular joint restores joint congruency and minimizes contact pressures, yet operative fixation of syndesmotic ankle injuries is frequently complicated by malreduction of the syndesmosis. Current methods of assessing reduction have been shown to be inadequate. As such, additional methods to judge the accuracy of syndesmotic reduction are required...

OBJECTIVES: To test the hypothesis that a fourfold CAIPIRINHA accelerated, 10-min, high-resolution, isotropic 3D TSE MRI prototype protocol of the ankle derives equal or better quality than a 20-min 2D TSE standard protocol. METHODS: Following internal review board approval and informed consent, 3-Tesla MRI of the ankle was obtained in 24 asymptomatic subjects including 10-min 3D CAIPIRINHA SPACE TSE prototype and 20-min 2D TSE standard protocols. Outcome variables included image quality and visibility of anatomical structures using 5-point Likert scales...

REVIEW
Matthew L Vopat, Bryan G Vopat, Bart Lubberts, Christopher W DiGiovanni
Ideal management of the various presentations of syndesmotic injury remains controversial to this day. High quality evidentiary science on this topic is rare, and numerous existing studies continue to contradict one another. The primary reasons for these discrepancies are that previous studies have failed to (1) properly distinguish between isolated (non-fractured) and non-isolated injuries, (2) accurately define stable from unstable injuries, and (3) sufficiently differentiate between acute and chronic injuries...

BACKGROUND: No general consensus has yet been established for the gold standard treatment of ankle syndesmotic complex injuries. Recent literature has documented the success of ankle tightrope fixation for heterogeneous ankle fracture patterns, resulting in syndesmotic complex injuries. We present a multicentre case series assessing the clinical, radiological and functional outcomes of patients with Weber C ankle fractures treated with the Arthrex TightRope(®) fixation system. METHOD: We performed a retrospective analysis of all adult patients with Weber C ankle fractures who were treated with the Arthrex TightRope(®) fixation system at four centres over a 3-year period...

Suture button devices such as the TightRope (Arthrex, Naples, Florida) have been increasingly used for syndesmotic fixation of ankle fractures. Despite proposed advantages, prior studies have shown equivalent outcomes, with a theoretical decreased need for removal of hardware. Complications of suture button fixation of syndesmotic instability may be underreported and include lateral suture knot inflammation with or without granuloma formation, infection, aseptic osteolysis with widening of the tibial drill tunnels, heterotopic ossification, and osteomyelitis...

Incisura fibularis (IF) is an important landmark in assessing syndesmotic stability radiologically postinjury. The purpose of this review was to explore the anatomy and morphometrics of this widely used anatomical landmark and to further the understanding of the same. A systematic review was conducted online using PubMed and Google Scholar, per PRISMA guidelines. Predefined eligibility criteria were applied, and the data thus compiled were analyzed. Wide variability in morphometrics and, thus, anatomy of IF were observed in the present review, which was influenced by gender...

BACKGROUND: While trans-syndesmotic fixation with metal screws is considered the gold standard in treating syndesmotic injuries, controversy exists regarding the need and timing of postoperative screw removal. Formal recommendations have not been well established in the literature and clinical practice is highly variable in this regard. The purpose of this systematic review is to critically examine the most recent literature regarding syndesmotic screw removal in order to provide surgeons an evidence-based approach to management of these injuries...

Articular cartilage and bony contact at the distal tibiofibular cartilage contact zone (TFCCZ) is variable. The appropriate placement of syndesmotic hardware would benefit from a more accurate characterization of the proximal extent of the TFCCZ allowing surgeons to place hardware that simultaneously improves biomechanical stability and decreases the risk of iatrogenic cartilage damage. In addition, Ilizarov wire fixation through the distal fibula and tibia can pass through the syndesmosis recess. Anatomically defining the proximal extent of this recess can help decrease the risk of inadvertent capsular penetration...

We conducted a study to determine the incidence of syndesmotic injury and stabilization within various ankle fracture patterns along with the rate of syndesmotic implant removal. All data were obtained from a publicly available for-fee healthcare database, the PearlDiver Patient Records Database. Current Procedural Terminology (CPT) codes were used to search the database for cases of fixation of lateral malleolus, bimalleolar, and trimalleolar fractures in addition to syndesmotic fixation and implant removal...

RATIONALE: Ankle syndesmotic injuries occasionally require long-term therapy for recovery and can result in tendon injury. Posterior tibial tendon dysfunction (PTTD) is an acquired deformity that can cause flatfoot deformity. The current nonoperative management of PTTD includes nonsteroidal antiinflammatory drugs (NSAIDs), orthopedic devices. Although various treatment options have been attempted, optimal treatments for each stage of the condition are debated. Polydeoxyribonucleotide (PDRN) is effective in healing of chronic wounds associated with tissue damage by attracting tissue growth factors...
