BACKGROUND: Talus is a well-supported bone in the foot. A fracture of talus requires a high-impact injury. A wedge-shaped inferolateral component is the lateral process of the talus (LPT). A fracture of LPT is also known as a 'snowboarder's fracture'. Simultaneous bilateral snowboarder's fracture is rarely reported in English literature. CASE: We present here a case of simultaneous bilateral snowboarder's fractures in a slow-moving motor vehicle accident in the icy conditions...

Matthew P Sullivan, Reza Firoozabadi
Talar fractures are some of the most challenging injuries that orthopaedic traumatologists manage. The current knowledge of functional alterations with regard to malreduction of talar fractures is well established. Decision making with regard to timing, approach, and implant selection as well as strategies to help achieve accurate restoration of talar anatomy substantially affect outcomes and must be carefully considered. Perfect anatomic talar reconstruction should always be attempted, and orthopaedic surgeons should have a strong working knowledge of the vascular, three-dimensional, and radiographic anatomy of the talus before performing talar surgery...

BACKGROUND: Total ankle arthroplasty (TAA) is an alternative to arthrodesis, but no randomized trial has examined whether a fixed bearing or mobile bearing implant provides improved gait mechanics. QUESTIONS/PURPOSES: We wished to determine if fixed- or mobile-bearing TAA results in a larger improvement in pain scores and gait mechanics from before surgery to 1 year after surgery, and to quantify differences in outcomes using statistical analysis and report the standardized effect sizes for such comparisons...

BACKGROUND: The presence of nonunion of a talar fracture with displacement, together with complete avascular necrosis, is a challenging entity to treat. METHODS: Twelve patients, 8 men (66.7%) and 4 women (33.3%), with nonunited talar fractures and extensive avascular necrosis of the talus were included. The average age was 27.7 years (range, 19-38 years). After exclusion of infection, the patients underwent resection of necrotic bone, bulk autograft, and fusion using an intramedullary nail...

BACKGROUND: Trauma to the talus can result in fracture, avascular necrosis and structural collapse. Treatment has been limited to surgical fusion and total ankle arthroplasty. Total ankle arthroplasty may not be an appropriate treatment for avascular necrosis while surgical fusion of the joint limits mobility. Custom-made implants have recently been used to address these limitations but have lengthy delays between injury and surgery and higher associated costs. A generic talar prosthesis available in various sizes may serve as a suitable alternative...

REVIEW
Patrick R Burns, Augusta Dunse
Tibiotalocalcaneal arthrodesis is a safe and viable option to treat patients with arthridities affecting ankle and subtalar joints, neuromuscular disorders, avascular necrosis of the talus, failed ankle arthrodesis, instability, and Charcot neuroarthropathy. Choice of incision and fixation is based on deformity, pathology, prior surgery and hardware, and surgeon comfort and preference. Intramedullary nails offer high primary stability, reduce sustained soft tissue damage, and may allow for earlier return to activities than traditional plate or screw constructs...

[Purpose] To report an adolescent male basketball player with nonhealing stress fractures of the foot and discuss the probable factors. [Subject and Methods] A 13-year-old basketball player presented with right foot pain. He had been playing basketball for three years and practicing 5 days/week. He denied any increase in daily training intensity. Magnetic resonance imaging confirmed stress fractures of the cuboid and cuneiform, with mild edema of the soft tissues between the tarsal bones and tenosynovitis of the flexor hallucis and flexor digitorum longi...

Irreducible ankle fracture-dislocations are very rare entities. The present case report demonstrates an unusual finding of tibialis posterior and flexor digitorum longus tendons interposed in the tibiofibular joint impairing successful closed reduction of ankle fracture-dislocation. A 45-year-old patient presented with a bimalleolar pronation-external rotation ankle fracture-dislocation after a motorcycle accident. Attempts to perform closed reduction before surgery were unsuccessful. Subsequent urgent open reduction and internal fixation surgical management revealed interposition of the tibialis posterior and flexor digitorum longus tendons in the tibiofibular joint...

The Bosworth fracture is a pattern of fracture-dislocation of the ankle joint with fixed dislocation of the proximal part of the fibula behind the posterior malleolus. It is a rare injury, which requires high index of suspicion for diagnosis. Fixed dislocation of the fibula does not allow for closed reduction, so open reduction and fixation of fibula or tibia is required. We present a case report of a patient who suffered a Bosworth fracture, with associated medial malleolus fracture. She underwent surgical treatment with open reduction and internal fixation of the fibula and tibia...

BACKGROUND: Pantalar dislocations without associated talar fracture are rare and have high risks of complications, including infection, osteonecrosis, and posttraumatic osteoarthrosis. Limited information on later function exists. This study evaluated complications and outcomes following pantalar dislocation without talar fracture. METHODS: Nineteen patients were identified with open (n = 14) or closed (n = 5) pantalar dislocations without talar fracture. Ten male and 9 female patients with a mean age of 39...

Anterior arthroscopic tibiotalar arthrodesis has been well codified. A posterior approach with the patient in prone position is indicated when the anterior approach is precluded by soft tissue issues or for a 1-step procedure associated with posterior subtalar fusion. In an anatomic study, we assessed the feasibility of posterior arthroscopic tibiotalar fusion and sought to determine the arthroscopy entry points, mortise cartilage freshening quality, and risk of osseous, tendinous, vascular, and neural complications...

OBJECTIVE: To investigate the optimal posterior screw placement and the geometry of safe zones for screw insertion in the talar neck. METHODS: Computed tomography data for 15 normal feet were imported into Mimics 10.01 software for 3-dimensional reconstruction; 4.0-mm-diameter screws were simulated from the lateral tubercle of the posterior process of the talus to the talar head. The range of screw paths trajectories and screw lengths at nine locations that did not breach the cortex of the talus were evaluated...

Extruded talus is a rare serious result from a high-energy injury to a supinated and plantar flexed foot. Treatment remains controversial with a lack of congruent evidence for talar reimplantation. A 34-year-old woman was involved in a road traffic accident at 40 mph. Imaging revealed a left talus extruded anterolaterally with a talar neck fracture. Additional injuries included right acetabular fracture, transverse process fractures and rib fractures, which were treated conservatively. The talus was reimplanted and the talar neck fixed with a cortical screw...

Stress fractures of the foot and ankle are a commonly encountered problem among athletes and individuals participating in a wide range of activities. This illustrated review, the second of two parts, discusses site-specific etiological factors, imaging appearances, treatment options, and differential considerations of stress fractures of the foot and ankle. The imaging and clinical management of stress fractures of the foot and ankle are highly dependent on the specific location of the fracture, mechanical forces acting upon the injured site, vascular supply of the injured bone, and the proportion of trabecular to cortical bone at the site of injury...

BACKGROUND: The positioning of the fracture fragment of a posterior malleolus fracture is critical to healing and a successful outcome as malunion of a posterior malleolar fracture, a condition seen in clinical practice, can affect the dynamics of the ankle joint, cause posterolateral rotational subluxation of the talus and ultimately lead to destruction of the joint. Current consensus is to employ anatomic reduction with internal fixation when the fragment size is larger than 25 to 33% of the tibial plafond...

BACKGROUND: Mobile-bearing total ankle replacement (TAR) enables motion at the tibial implant-polyethylene insert interface. This motion could lead to coronal translation of the talus relative to the tibia and may affect radiographic outcome. We aimed to assess the translation of the talus before and after mobile-bearing TAR to determine whether translation of the talus after TAR is associated with coronal plane alignment of the lower limb and hindfoot as well as to investigate the complications associated with talar translation...
