- Templating of Syndesmotic Ankle Lesions by Use of 3D Analysis in Weightbearing and Nonweightbearing CT. [Journal Article]
- FAFoot Ankle Int 2018 Aug 20; :1071100718791834
- CONCLUSIONS: This study evaluated an effective method for quantifying a unilateral syndesmotic lesion of the ankle. Applications in clinical practice could improve diagnostic accuracy and potentially aid in preoperative planning by determining which correction needs to be achieved to have the fibula correctly reduced in the syndesmosis.

Despite a considerable amount of research, the deficits causing recurrent sprains in people with chronic ankle instability are still unclear. Changes in frontal plane kinematics and decreased peroneal activation have been proposed as potential underlying mechanisms, but whether people with ankle instability show deficits in control of injury-relevant movements is not well understood. Therefore, the purpose of the present study was to analyse ankle joint kinematics and kinetics as well as neuromuscular activation during dynamic change-of-direction movements. Eighteen participants with functional instability, 18 participants with functional and mechanical instability and 18 healthy controls performed 45° sidestep-cutting and 180° turning movements in reaction to light signals. During sidestep-cutting both instability groups displayed significantly lower inversion angles than controls when the trials with the highest maximum inversion angle of each participant were compared. In turning movements, participants with functional instability presented significantly lower average maximum inversion angles than controls as well as higher peroneal activation before foot strike than participants with both functional and mechanical instability. We theorize that the observed changes in movement kinematics of participants with chronic ankle instability are the result of a protective strategy to limit frontal plane ankle joint loading in potentially harmful situations.
- Bilateral Talus and Navicular Fractures accompanied with Unilateral Calcaneal Fracture: A Case Report. [Journal Article]

An 18-year old male patient, with a history of paragliding accident, sustaining a coronal shear fracture of the body of the talus, an anterior process fracture of the calcaneus extending to the calcaneocuboid joint and a nondisplaced navicular body fracture at the right foot and a displaced fracture of the navicular body accompanied with posteromedial process fracture of the talus at the left side was referred to our emergency clinic. For the right foot, the coronal plane fracture of the talar body was anatomically reduced and fixed with screws. For the left foot, screw fixation was performed through the lateral aspect to fix the large posteromedial fragment. Small bone fragments were removed from the left navicular fracture, and the main fragments were also fixed with screw. The talo-navicular joint was stabilised with a Kirschner wire. At 36 months follow-up, bilateral foot and ankle functions were satisfactory, Maryland scores of the right and left foot were 85 (good) and 90 (excellent), respectively, and the patient regained his full activity level by the 5th month postoperatively. With reference to the number and types of fractures in this one patient, we present a standard protocol for treatment of isolated talus, navicular and calcaneal fractures presenting together in a single foot injury.
- Application of Cinematic Rendering in Clinical Routine CT Examination of Ankle Sprains. [Journal Article]
- AAAJR Am J Roentgenol 2018 Aug 14; :1-4
- CONCLUSIONS: Cinematic rendering technique may be primarily used to deliver visual information to patients, physicians, and virtual anatomy classes. Postprocessing requires more time than traditional methods do, which can be a hindrance in clinical work.
- Neuromuscular control of ankle and hip during performance of the star excursion balance test in subjects with and without chronic ankle instability. [Journal Article]
- PlosPLoS One 2018; 13(8):e0201479
- CONCLUSIONS: Alteration in proximal and distal muscle activity appears to negatively affect postural control and quality of movement, which may lead to prolonged functional impairments. Hence, implementing hip and ankle muscle exercises in the rehabilitation of ankle instability might benefit these patients.

Ultrasonography (US) has been increasingly used in the evaluation of ankle ligamentous injuries given its advantages as a dynamic, efficient, noninvasive, and cost-effective imaging method. Understanding the anatomy of the ankle ligaments is critical for correct diagnosis and treatment. This pictorial essay describes and illustrates the US scanning technique and potential pitfalls in evaluating the ankle ligaments and also provides an overview of the US appearance of normal and injured ankle ligaments with magnetic resonance imaging correlation. Highlighted structures include the lateral complex, medial/deltoid complex, spring (calcaneonavicular) ligament complex, and syndesmosis.
- Coalitions of the Tarsal Bones. [Review]

Tarsal coalitions are the result of impaired mesenchymal separation of the tarsal bones. The most common types include calcaneonavicular or talocalcaneal coalitions. Subtalar stiffness results in pathologic kinematics with increased risk of ankle sprains, planovalgus foot deformity, and progressive joint degeneration. Resection of the coalition yields good results. Tissue interposition may reduce the risk of reossification, and concomitant deformity should be addressed in the same surgical setting.

Lateral talar process fractures (LTPF) are uncommon injuries but have become more relevant with snowboarding. Currently the fractures are classified according to McCrory-Bladin into 3 types, with advice for treatment that is not ideal anymore. This article proposes modifying the existing classification by differentiating the multifragmented type III into 3 subtypes: IIIa, articular multifragmented but metaphyseal simple; IIIb, articular and metaphyseal multifragmented but reconstructable; and type IIIc, comminuted and nonreconstructable. A treatment-algorithm is presented. Undisplaced fractures are usually treated conservatively and displaced are an indication for surgery. In general, the outcome is good to excellent, if timely diagnosed and adequately treated.

- Propagation of Syndesmotic Injuries During Forced External Rotation in Flexed Cadaveric Ankles. [Journal Article]
- OJOrthop J Sports Med 2018; 6(6):2325967118781333
- CONCLUSIONS: Plantar flexion decreased and dorsiflexion increased the incidence of syndesmotic injuries compared with neutral matched-pair ankles. Injury propagation was not identical in all ankles that sustained a syndesmotic injury, but a characteristic sequence initiated with injuries to the medial ligaments, particularly the superficial deltoid, followed by the propagation of injuries to either the syndesmotic or lateral ligaments (depending on ankle flexion), and finally to the interosseous membrane or the fibula.
