For AO 44-B2 ankle fractures of uncertain stability, the current diagnostic standard is to obtain a gravity stress radiograph, but some have advocated for the use of weight-bearing radiographs. The primary aim was to compare measures of medial clear space (MCS) on weight-bearing cone beam computed tomography (CBCT) scans versus gravity stress radiographs for determining the state of stability of ankle fractures classified as AO SER 44-B2 or Weber B. The secondary aim was to evaluate the details offered by CBCT scans with respect to other findings that may be relevant to patient care...

PURPOSE: Avascular necrosis of the talus is one of the most notable complications associated with talar neck fractures with frequent evolution of the osteonecrosis into a difficult arthrodesis. We tested whether the injection of bone marrow mesenchymal stem cells (MSCs) could improve the repair process of the osteonecrosis. MATERIAL AND METHODS: Forty-five early (without collapse) post-traumatic talus osteonecroses (group 1; study group) were treated between 1995 and 2012 with percutaneous injection of progenitor cells (autologous bone marrow concentrate from the iliac crest)...

INTRODUCTION: The management of pilon fractures remains a challenging issue. Due to the complexity of factors that influence the outcome, it has been questioned if anatomical reductions of articular fracture are relevant. The lack of a commonly accepted assessment of quality of fracture reduction compounded the uncertainty of the importance of anatomical reduction in pilon fracture. The current study aimed to define parameters that can better assess the reduction quality and to investigate the influence of reduction quality on functional outcomes...

Fracture-dislocations of the talus are one of the most complex injuries involving the foot and ankle. These injuries are often accompanied by additional traumatic orthopedic injuries, avascular necrosis, and infection. When approaching limb reconstruction and salvage, the overall prognosis and functionality of the limb are key factors to consider. In the present report, we draw attention to the importance of a multidisciplinary team approach for formulating a treatment plan that incorporates the talar injury and associated injuries or pathologic features...

Talar fractures account for <1% of all fractures in the body and 3% to 6% of pedal fractures. Of these fractures, avulsion and neck fractures represent the most and second most common type, respectively. Several classification systems exist for talar fractures of the talar dome (Berndt-Hardy), talar neck dislocation (Hawkins), and talar body (Sneppen) anatomic locations. Although diverse, they are not all encompassing for fracture patterns of the talus. Another set of pathologic issues occur about the talar head and neck region that can be seen in the clinical setting...

BACKGROUND: Lateral talar process fractures (LTPF) are often missed on conventional radiographs. A positive V sign is an interruption of the contour of the LTP. It has been suggested, but not proven to be pathognomonic for LTPF. The objective was to study whether the V sign is pathognomonic for LTPF and if it can be properly assessed in different ankle positions and varying fracture types. METHODS: An experimental study was conducted. Two investigators assessed lateral radiographs (n = 108) of a foot and ankle model...

The two-portal hindfoot arthroscopy is an effective procedure enabling direct visualisation of posterior ankle pathology with low invasiveness.An important stage of the hindfoot endoscopy is localisation of the flexor hallucis longus (FHL) tendon to protect the neurovascular bundle which is located just medial to it.Posterior ankle impingement syndrome and FHL tenosynovitis are common causes of posterior ankle pain and frequently occur together.Posteriorly localised talar osteochondral lesions, Achilles tendon disorders, osteoarthritis, talar bone cysts and talar fractures are among the other pathologies that can be treated with hindfoot arthroscopy...

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...

RANDOMIZED CONTROLLED TRIAL
Robin M Queen, Christopher T Franck, Daniel Schmitt, Samuel B Adams
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: 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...
