BACKGROUND: The purpose of this study was to evaluate the clinical and radiologic outcomes of patients younger than 20 years, treated with the arthroscopic-talus autologous matrix-induced chondrogenesis (AT-AMIC) technique and autologous bone graft for osteochondral lesion of the talus (OLT). METHODS: Eleven patients under 20 years (range 13.3-20.0) underwent the AT-AMIC procedure and autologous bone graft for OLTs. Patients were evaluated preoperatively (T0) and at 6 (T1), 12 (T2), and 24 (T3) months postoperatively, using the American Orthopaedic Foot & Ankle Society Ankle and Hindfoot (AOFAS) score, the visual analog scale and the SF-12 respectively in its Mental and Physical Component Scores...

Introduction Talar dislocation fractures of type IV (Marti and Weber) are extremely rare injuries with special challenges to the surgeon and poor results. Due to their low incidence and the sparse literature, it is unclear what is the optimal treatment and how complications can be minimised. Material and Methods A literature research was carried out using the online medical database "PubMed". The findings of the literature were then applied to a clinical case of type IV talar dislocation fracture (Marti and Weber)...

: The talus is the second most common fractured tarsal bone. While their incidence may be low, talus fractures are severe injuries that can lead to long-term disability and pain. Displaced talar body fractures are typically treated through an open approach with the aim of obtaining anatomic reduction and stable fixation. There are several case reports in the literature demonstrating successful management of talus fractures arthroscopically. An arthroscopic approach minimizes soft tissue trauma, which can help decrease postoperative wound complications and infections...

BACKGROUND: Previous studies have documented the high costs of non-dialysis dependent chronic kidney disease (CKD) but out-of-pocket healthcare expenditures remain poorly explored. This study described total direct and out-of-pocket expenditures for adults with non-dialysis dependent CKD and compared expenditures with those for cancer or stroke. METHODS: This study used data from the 2011-2013 Medical Expenditure Panel Survey, a national survey of healthcare expenditures in the U...

PURPOSE OF THE STUDY Peripheral fractures of the talus (lateral talar process and posterior talar process) are rare injuries, easy to miss on examination due to their location and clinical manifestation. They account for 0.3% to 1.0% of all fractures of the talus. An incorrect or late treatment of talar process fractures can result in permanent pain, impingement syndrome, healing in malposition, pseudoarthrosis development and also, due to joint instability, in a potential development of severe subtalar arthritis...

We describe a rare case of simultaneous and spontaneous osteonecrosis affecting bilateral navicular and talar bones in a young male. On both sides, there was associated symptomatic talonavicular and naviculocuneiform arthritis. The more symptomatic left foot was managed successfully by talonavicular-cuneiform (TNC) arthrodesis and core decompression of talar body. A probable cause of this rare disorder was most likely due to a developmental anomaly in the preaxial ray of the foot. As no literature is currently available for this rare condition, our case report is intended to provide a referral point for future studies in the early diagnosis and management of this condition...

Fractures of talus are relatively uncommon injuries with majority of them involving the neck region. Talar body fracture in sagittal plane in combination with medial malleolus fracture is very rare with few cases being reported in the literature earlier. We report such an unusual combination in an adolescent, which was treated with open reduction and internal fixation with screws for both talus and medial malleolus. This was followed by physiotherapy and non-weight bearing till the fracture united.

Pancreatic neuroendocrine tumors (PNETs) are heterogeneous neoplasms which represent only 2% of all pancreatic neoplasms by incidence, but 10% by prevalence. Genetic risk factors could have an important role in the disease aetiology, however only a small number of case control studies have been performed yet. To further our knowledge, we genotyped 13 SNPs belonging to the pleiotropic CDKN2A/B gene region in 320 PNET cases and 4436 controls, the largest study on the disease so far. We observed a statistically significant association between the homozygotes for the minor allele of the rs2518719 SNP and an increased risk of developing PNET (ORhom = 2...

EDITORIAL
C Niek van Dijk
In general, osteochondral allograft should include minimal "osteo" or bone. In cases that require a bulk allograft, even after creeping substitution and healing, most of the graft remains dead bone. Bulk dead bone is a particular problem in the talus, should a patient need revision to a prosthesis or arthrodesis. As an alternative, drilling, bone grafting, and fixation of existing cartilage, when possible, is preferred.

BACKGROUND: In recent years, the number of total ankle arthroplasty procedures performed has increased dramatically. We sought to report the clinical results of the largest cohort of patients treated with a modern fixed-bearing total ankle arthroplasty by a single surgeon. METHODS: We retrospectively reviewed the charts of 78 consecutive patients (81 ankles) who underwent total ankle arthroplasty with a minimum clinical follow-up of 2 years. Sixty-three patients completed standardized questionnaires including the Foot and Ankle Disability Index (FADI), the Short Musculoskeletal Function Assessment (SMFA), the Short Form (SF)-36v2, and a visual analog scale (VAS) for pain...

We investigated the effect of combined fibular osteotomy on the pressure of the tibiotalar and talofibular joints in medial opening-wedge supramalleolar osteotomy. Three different tibial osteotomy gaps (6, 8, and 10 mm) were created in 10 cadaveric models, and the pressure in the tibiotalar and talofibular joints was measured under axial load before and after fibular osteotomy. The heel alignment angle and talar translation ratio were evaluated radiographically. An increase in osteotomy gap led to increases in hindfoot valgus (p = ...

During the previous 2 decades, numerous surgical procedures have become available to treat osteochondral lesions of the talus. The objective of the present study was to use 7 Tesla (7T) magnetic resonance imaging (MRI) to quantify and compare T2 values (a marker of collagen architecture) of native tibiotalar cartilage and cartilage repair tissue in patients treated with a juvenile particulate allograft for osteochondral lesions of the talus. The institutional review board approved the present study, and all subjects provided written informed consent...

Total ankle replacement (TAR) is an accepted treatment for end-stage ankle arthritis. When concurrent subtalar joint pathologic features exist, ipsilateral subtalar joint arthrodesis (STJA) can be performed either simultaneous with TAR or as a staged procedure. Limited data exist on the effect of talar component subsidence and prosthesis survivorship. The present study purpose was to evaluate the effect of STJA on talar component subsidence after primary TAR and its effect on TAR survivorship. All patients, a minimum of 18 years old, from a single institution with modern-generation TAR and 1-year minimum follow-up data available were evaluated...

PURPOSE: To assess and evaluate healing and functional outcomes after arthroscopic talus autologous matrix-induced chondrogenesis (AT-AMIC) in 2 age groups: patients older than 33 years versus patients 33 years or younger. METHODS: A total of 31 patients, of whom 17 were 33 years or younger (G1) and 14 older than 33 years (G2), were evaluated. All patients were treated with AT-AMIC repair for osteochondral talar lesion. Magnetic resonance imaging (MRI) and computed tomography (CT)-scan evaluations, as well as clinical evaluations measured by the visual analog scale (VAS) score for pain, American Orthopaedic Foot and Ankle Society Ankle and Hindfoot score (AOFAS), and Short Form-12, were performed preoperatively (T0) and at 6 (T1), 12 (T2), and 24 (T3) months postoperatively...

BACKGROUND: Single Photon Emission Computed Tomography-Computed Tomography (SPECT/CT) gains an important part of diagnostics in patients with osteochondral lesions (OCL). SPECT/CT is a hybrid imaging modality, which combines a 3D scintigraphy (SPECT) and computerized tomography (CT) into one single procedure and combines metabolic data, structural and mechanical information. The purpose of the study was to develop and evaluate a standardized method to anatomically localize and quantitatively analyze the bone SPECT tracer activity of the ankle joint using SPECT/CT...

BACKGROUND: Implant survivorship is dependent on accuracy of implantation and successful soft tissue balancing. System instrumentation for total ankle arthroplasty implantation has a key influence on surgeon accuracy and reproducibility. The purpose of this study was to determine the accuracy and reproducibility of implant position with patient-specific guides for total ankle arthroplasty across multiple surgeons at multiple facilities. METHODS: This retrospective, multicenter study included 44 patients who received a total ankle implant (INBONE II Total Ankle System; Wright Medical Technology, Memphis, TN) using PROPHECY patient-specific guides from January 2012 to December 2014...

BACKGROUND: Verifying the exact location of talocalcaneal (TC) coalition is important for surgery, but the complicated anatomy of the subtalar joint makes it difficult to visualize on radiographs. No study has used computed tomography (CT) or magnetic resonance imaging (MRI) to verify the radiological characteristics of TC coalition or those of different facet coalitions. Therefore, this study verified the radiological findings used to identify TC coalitions and those of different facet coalitions using CT and MRI...
