PURPOSE: To evaluate the difference between T2 relaxation values of the subtalar cartilage in lateral ankle instability patients and healthy volunteers. MATERIALS AND METHODS: This institutional review board-approved study included 27 preoperative magnetic resonance imaging (MRI) examinations of 26 patients who underwent Broström operations. Data of previously enrolled healthy volunteers (12 volunteers, 13 MRIs) were used as controls. Two radiologists independently measured T2 values in eight posterior subtalar joint cartilage compartments: central calcaneus anterior (CCA) and posterior (CCP), central talus anterior (CTA) and posterior (CTP), lateral calcaneus anterior (LCA) and posterior (LCP), and lateral talus anterior (LTA) and posterior (LTP)...

BACKGROUND: The aim of the study was to investigate parameters influencing the preoperative pain intensity in patients with osteochondral lesions of the ankle. The evaluation covered patient-related parameters such as age, sex, body mass index (BMI), as well as defect-related parameters, such as localisation, size and stage (according to the classification of the International Cartilage Repair Society [ICRS] and the Berndt-Harty-Loomer classification). We also examined the correlation between the different surgical techniques and additional factors, such as debridement of an impingement or stabilisation of the ankle on the one hand, and the preoperative pain intensity on the other...

Talar head fractures represent a rare subtype of injury to the talus. Clinical series of talar head fractures are nonexistent in the current literature and treatment of these injuries is based on expert opinion. Many authors recommend a single incision approach to open reduction and internal fixation of talar head fractures, however we have found that a two incision approach allows for optimal visualization while facilitating proper implant placement. We present a description of our technique and our clinical experience treating 8 of these rare injuries...

Fractures of the lateral and the posterior processes of the talus are uncommon and frequently missed because of a low level of suspicion and difficulty in interpretation on plain radiographs. Missed fractures can lead to persistent pain and reduced function.Lateral process fractures are usually a consequence of forced dorsiflexion and inversion of fixed pronated foot. These are also commonly known as snowboarder's fractures.The posterior process of the talus is composed of medial and lateral tubercles, separated by the groove for the flexor hallucis longus tendon...

Treatment for talar avascular necrosis is challenging. This study evaluates the feasibility of a generic talar implant by cadaveric assessment. Ten cadaveric ankles were CT-scanned to determine talar implant size. The opposite ankles were CT-scanned with the biological talus and then with the implant. 3D ankle geometry was reconstructed and implant position was compared to the biological talus position. The averages among specimens' positive and negative average-deviations were 0.91 mm and 0.70 mm. Seventy percent of talar dome deviations between the biological talus and implant were within an acceptable range...

Some ankle sprains hide important lesions beyond the classic lateral ligament complex injuries. The lateral inverted osteochondral fracture of the talus (LIFT) represents a rare osteochondral lesion, whose diagnosis relies on a high clinical suspicion followed by correct image study interpretation. We present a successful arthroscopic fixation of a LIFT lesion in a 45-year-old active man. At 8 months follow-up, the patient was pain free and able to return to his daily activities without limitation. The imagiological study showed osteochondral fragment consolidation with no signs of hardware failure...

The purpose of this study was to quantify isolated coupling mechanisms of calcaneal adduction/abduction and calcaneal eversion/inversion to proximal bones in vitro. The in vitro approach is necessary because in vivo both movements appear together, making it impossible to determine the extent of their individual contribution to overall ankle joint coupling. Eight fresh frozen foot-leg specimens were tested. Data describing bone orientation and coupling mechanisms between segments were obtained using bone pin marker triads...

Fractures of the lateral process of the talus are uncommon, but often overlooked. They can result in significant functional deficit with residual nonunion and arthritis if not recognized and treated appropriately. We describe 2 cases of such injuries, one with acute recognition and management, and one with delayed diagnosis and nonunion. In both cases, pain from the fracture was accompanied by symptoms of instability requiring simultaneous lateral ligament reconstruction along with fracture fixation. Evaluation of patients with lateral process fractures should include assessment of the lateral ligaments; ankle instability may need to be surgically addressed along with intervention for fracture fixation...

PURPOSE: Autologous osteochondral transplantation is an established treatment for large-sized osteochondral lesions of the talus (OLT) with excellent short term outcomes. However, few studies assess the outcomes of autologous osteochondral transplantation at mid-term follow-up. The purpose of the current systematic review was to evaluate the clinical outcomes of the autologous osteochondral transplantation procedure in the treatment of OLT at mid-term and long-term follow-up. METHODS: A systematic search of the MEDLINE, EMBASE and Cochrane Library databases was performed in October 2017 based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

BACKGROUND Fractures of the talus are uncommon injuries that usually involve the talar neck, rather than the talar body. This report is of a rare case of combined left talar neck fracture and adjacent joint dislocation with an ipsilateral bimalleolar ankle fracture. CASE REPORT A 37-year-old man presented with an injury to his left foot following a motor vehicle accident. When he presented to the hospital emergency department, his left foot and ankle were swollen, the overlying skin was intact but badly contused, and there was no neurovascular deficit...

The case we present suggests that it might be possible to overcompress the syndesmosis, causing subluxation of the talus within the ankle mortise. A 26-year-old female patient had had a Weber Type C ankle fracture internally fixed with a lateral plate and syndesmosis screws. Despite the fibula appearing well reduced and computed tomography imaging showing a well-aligned fibula within the fibular notch, anteromedial subluxation of the talus was present in the ankle mortise. Examination with the patient under anesthesia revealed a stable syndesmosis fixation; however, talar malpositioning was not affected by the foot position...

BACKGROUND: Recent studies have reported promising clinical results after osteochondral autograft transplantation (OAT) for the treatment of large osteochondral lesions of the talus (OLT). However, no study has yet compared clinical outcomes between primary and secondary OAT for large OLT. PURPOSE: The purpose is to compare clinical outcomes among patients with large OLT who receive primary OAT versus those who receive secondary OAT after failure of marrow stimulation and to identify factors associated with clinical failure...

BACKGROUND: Third generation total talar prostheses (TTPs) are viable options for talar avascular necrosis (AVN) in the absence of neighboring joint pathology. The use of modern three-dimensional (3D) printing allows the production of custom implants that exactly mimic the patient's anatomy. The aim of this study is to determine the accuracy of 3D printing in reproducing a synthetic talus and, in doing so, restoring more normal anatomical relationships. We hypothesize that this mode of replication will restore and maintain normal radiographic alignment of the ankle, subtalar, and forefoot joints in the setting of talar AVN...

BACKGROUND: An acute ankle sprain can result in a bony avulsion of the lateral ankle ligaments. The extent of concomitant lesions and subsequent instability patterns are not clearly understood. The high incidence of old avulsion fractures found in symptomatic chronic ankle instability may indicate the need for primary fixation. METHODS: Ten patients (5 male, 5 female; mean age, 34 years; range, 15-64 years) with bony avulsion fractures of the fibula after acute ankle sprains were included...

Talus fractures are rare but often associated with complications and significant post-traumatic patient morbidity. They frequently occur at high-energy traumas such as traffic accidents. This is a case report of a young woman who after a fall from a roof, presented in an emergency department with a dislocated ankle which was initially misdiagnosed as a bimalleolar fracture and attempted repositioned as such before X-ray. Dislocated talus fractures, however, need urgent anatomic reduction after diagnostic imaging and often subsequent and acute osteosynthesis...
