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...

Pancreatic neuroendocrine neoplasms (pNEN) account for less than 5% of all pancreatic neoplasms and genetic association studies on susceptibility to the disease are limited. We sought to identify possible overlap of genetic susceptibility loci between pancreatic ductal adenocarcinoma (PDAC) and pNEN; therefore, PDAC susceptibility variants (n=23) from Caucasian genome-wide association studies (GWAS) were genotyped in 369 pNEN cases and 3,277 controls from the PANcreatic Disease ReseArch (PANDoRA) consortium to evaluate the odds associated with pNEN risk, disease onset and tumor characteristics...

Talus fractures with associated dislocations are rare but have high rates of complications, including avascular necrosis (AVN). Management of these injuries involves urgent surgical reduction and fixation, although there are no definitive data defining an operative time frame for preserving the blood supply and preventing complications. To determine the effect of time to surgical reduction of talus fractures and talus fracture-dislocations on rates of AVN and posttraumatic osteoarthritis (PTOA), we retrospectively reviewed talus fractures surgically managed at a level I trauma center during the 10-year period 2003 to 2013...

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)...

Juvenile allogenic chondrocyte implantation (JACI; DeNovo NT Natural Tissue Graft®; Zimmer, Warsaw, IN) with autologous bone marrow aspirate concentrate (BMAC) is a relatively new all-arthroscopic procedure for treating critical-size osteochondral lesions (OCLs) of the talus. Few studies have investigated the clinical and radiographic outcomes of this procedure. We collected the clinical and radiographic outcomes of patients who had undergone JACI-BMAC for talar OCLs to assess treatment efficacy and cartilage repair tissue quality using magnetic resonance imaging (MRI)...

BACKGROUND: Osteochondral lesions of the talus (OLT) are recognized as being commonly associated with trauma. However, the etiology of OLT remains unclear. In the case of a posteromedial lesion of OLT (medial OLT), the deep layer of the deltoid ligament is located close to the medial OLT, and this relationship between a medial lesion and deltoid ligament could be a risk factor for medial OLT. The purpose of this study is to investigate the unique anatomic feature of the deep deltoid attachment to the talus in patients with medial OLT compared with patients with non-medial OLT...

l-Talarate/galactarate dehydratase (TGD) is a member of the enolase superfamily of enzymes and catalyzes the dehydration of either meso-galactarate or l-talarate to form 5-keto-4-deoxy-d-glucarate (5-KDG). To facilitate study of this enzyme and other galactarate dehydratases, a continuous circular dichroism-based assay has been developed. Using recombinant enzyme from Salmonella typhimuium (StTGD), the rates of StTGD-catalyzed conversion of m-galactarate to 5-KDG were determined by following the change in ellipticity at 323 nm...

In recent years, some authors have reported accessory anterolateral talar facet impingement with flatfoot including peroneal spastic flatfoot. Conversely, to our knowledge, no case report has been published about accessory anterolateral talar facet impingement with tibialis spastic varus foot. We report the first case in a 22-year-old man with intellectual disability, bilateral cleft hands and type 1 diabetes mellitus. Since spraining his left ankle over a year earlier, he experienced left sinus tarsi pain while standing and walking...

INTRODUCTION: Charcot's neuroarthropathy of ankle leads to instability, destruction of the joint with significant morbidity that may require an amputation. Aim of surgical treatment is to achieve painless stable plantigrade foot through arthrodesis. Achieving surgical arthrodesis in Charcot's neuroarthropathy has a high failure rate. We assess the outcomes of retrograde intramedullary interlocked nailing in tibio-talar arthrodesis for Charcot's neuroarthropathy. MATERIALS AND METHODS: 42 diabetic patients with a mean age of 49 year underwent ankle tibio-talar arthrodesis using retrograde nailing for Charcot's neuroarthropathy...
