Traditional screw fixation of the syndesmosis can be prone to malreduction.
Ankle fractures are the fourth most common fracture requiring surgical management. The deltoid ligament is considered the primary stabilizer of the ankle against a valgus force. The management of the deltoid ligament in ankle fractures is currently a controversial topic no consensus exists regarding repair in the setting of ankle fractures. The purpose of this systematic review is to examine the role and indications for deltoid ligament repair in ankle fractures. A systematic database search was conducted with Medline, Pubmed and Embase for relevant studies discussing patients with ankle fractures involving deltoid ligament rupture and repair. The papers were screened independently and in duplicate by two reviewers. Study quality was evaluated using the MINORs criteria. Data extraction included post-operative outcomes, pain, range of motion (ROM), function, medial clear space (MCS), syndesmotic malreduction and complication rates. Following title, abstract and full text screening, 10 eligible studies published between 1987 and 2017 remained for data extraction (n = 528). The studies include 325 Weber B and 203 Weber C type fractures. Malreduction rate in studies with deltoid ligament repair was 7.4% in comparison to those without repair at 33.3% (p < 0.05). Eleven (4%) of deltoid ligament repair patients returned for re-operation to have implants removed in comparison to eighty three (42%) of those without repair (p < 0.05). There was no significant difference for pain, function, ROM, MCS and complication rates (p < 0.05). The mean operating time of deltoid ligament repair groups was 20 minutes longer than non-repair groups(p < 0.05). Deltoid ligament repair offers significantly lower syndesmotic malreduction rates and reduced re-operation rates for hardware removal when performed instead of transsyndesmotic screw fixation. When compared to non-repair groups, there are no significant differences in pain, function, ROM, MCS and complication rates. Deltoid ligament repair should be considered for ankle fracture patients with syndesmotic injury, especially those with Weber C. Other alternative syndesmotic fixation methods such as
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. 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 fracture, medial malleolus fracture, anterior talofibular ligament rupture, and posterior malleolus fracture). All patients had a minimum follow-up period of 17 months (mean 27 months (17 to 35)).Aims

Bone defects are frequently observed in anterior shoulder instability. Over the last decade, knowledge of the association of bone loss with increased failure rates of soft-tissue repair has shifted the surgical management of chronic shoulder instability. On the glenoid side, there is no controversy about the critical glenoid bone loss being 20%. However, poor outcomes have been described even with a subcritical glenoid bone defect as low as 13.5%. On the humeral side, the Hill-Sachs lesion should be evaluated concomitantly with the glenoid defect as the two sides of the same bipolar lesion which interact in the instability process, as described by the glenoid track concept. We advocate adding remplissage to every Bankart repair in patients with a Hill-Sachs lesion, regardless of the glenoid bone loss. When critical or subcritical glenoid bone loss occurs in active patients (> 15%) or bipolar off-track lesions, we should consider anterior glenoid bone reconstructions. The techniques have evolved significantly over the last two decades, moving from open procedures to arthroscopic, and from screw fixation to metal-free fixation. The new arthroscopic techniques of glenoid bone reconstruction procedures allow precise positioning of the graft, identification, and treatment of concomitant injuries with low morbidity and faster recovery. Given the problems associated with bone resorption and metal hardware protrusion, the new metal-free techniques for Latarjet or free bone block procedures seem a good solution to avoid these complications, although no long-term data are yet available.

Malreduction of the syndesmosis has been reported in up to 52% of patients after fixation of ankle fractures. Multiple radiological parameters are used to define malreduction; there has been limited investigation of the accuracy of these measurements in differentiating malreduction from inherent anatomical asymmetry. The purpose of this study was to identify the prevalence of positive malreduction standards within the syndesmosis of native, uninjured ankles. Three observers reviewed 213 bilateral lower limb CT scans of uninjured ankles. Multiple measurements were recorded on the axial CT 1 cm above the plafond: anterior syndesmotic distance; posterior syndesmotic distance; central syndesmotic distance; fibular rotation; and sagittal fibular translation. Previously studied malreduction standards were evaluated on bilateral CT, including differences in: anterior, central and posterior syndesmotic distance; mean syndesmotic distance; fibular rotation; sagittal translational distance; and syndesmotic area. Unilateral CT was used to compare the anterior to posterior syndesmotic distances.Aims

Ankle sprains have been shown to be the most common sports related injury. Ankle sprain may be classified into low ankle sprain or high ankle sprain. Low ankle sprain is a result of lateral ligament disruption. It accounts for approximately 25% of all sports related injuries. The ankle lateral ligament complex consists of three important structures, namely the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL) and posterior talofibular ligament (PTFL). The ATFL is the weakest and most easily injured of these ligaments. It is often described as a thickening of the anterolateral ankle capsule. The ATFL sits in a vertical alignment when the ankle is plantarflexed and thus is the main stabiliser against an inversion stress. T he CFL is extracapsular and spans both the tibiotalar and talocalcaneal joints. The CFL is vertical when the ankle is dorsiflexed. An isolated injury to the CFL is uncommon. Early diagnosis, functional management and rehabilitation are the keys to preventing chronic ankle instability following a lateral ligament injury. Surgery does not play a major role in the management of acute ligament ruptures. Despite this up to 20% of patients will develop chronic instability and pain with activities of daily living and sport especially on uneven terrain. Anatomic reconstruction for this group of patients is associated with 90% good to excellent results. It is important that surgery is followed by functional rehabilitation. One of the aims of surgery in patients with recurrent instability is to prevent the development of ankle arthritis. It should be noted that the results of surgical reconstruction are less predictable in patients with greater than 10 year history of instability. Careful assessment of the patient with chronic instability is required to exclude other associated conditions such as cavovarus deformity or generalised ligamentous laxity as these conditions would need to be addressed in order to obtain a successful outcome. High ankle sprain is the result of injury to the syndesmotic ligaments. The distal tibiofibular joint is comprised of the tibia and fibula, which are connected by anterior inferior tibiofibular ligament, interosseous ligament and the posterior inferior tibiofibular ligament (superficial and deep components). The mechanism of injury is external rotation and hyperdorsiflexion. High index of suspicion is required as syndesmotic injuries can occur in association of low ankle sprains. The clinical tests used in diagnosing syndesmotic injuries (external rotation, squeeze, fibular translation and cotton) do not have a high predictive value. It is important to exclude a high fibular fracture. Plain radiographs are required. If the radiograph is normal then MRI scan is highly accurate in detecting the syndesmotic disruption. Functional rehabilitation is required in patients with stable injuries. Syndesmotic injuries are often associated with a prolonged recovery time. Accurate reduction and operative stabilisation is associated with the best functional outcome in patients with an unstable syndesmotic injury. Stabilisation has traditionally been with screw
