OBJECTIVE The current diagnostic criterion for Chiari malformation Type I (CM-I), based on tonsillar herniation (TH), includes a diversity of patients with amygdalar descent that may be caused by a variety of factors. In contrast, patients presenting with an overcrowded posterior cranial fossa, a key characteristic of the disease, may remain misdiagnosed if they have little or no TH. The objective of the present study was to use machine-learning classification methods to identify morphometric measures that help discern patients with classic CM-I to improve diagnosis and treatment and provide insight into the etiology of the disease...

INTRODUCTION: Osteogenesis imperfect (OI) is a heterogeneous and complex connective tissue disorder that manifests with low bone density and fragility. More than 15 types of OI have been distinguished on a clinical and molecular basis, but the classical clinical classification previously proposed in Types 1-4 with the recent inclusion of Type 5 appears to be more suitable. The diagnosis is mainly made on clinical and radiographic findings with fractures caused by mild trauma, bowing deformities of long bones, and growth deficiency...

INTRODUCTION: Synovial hemangioma is a rare condition with <200 published case reports in world literature and is frequently misdiagnosed, leading to diagnostic delay of many years. This delay is even more significant if the patient comes from a rural background with a dearth of medical facilities in the area. This case had a lag of nearly 20 years from the time of onset of symptoms and the required management which is the maximum reported for any synovial hemangioma since most of them have been found and treated in adolescents...

BACKGROUND AND PURPOSE: Thoracic trauma remains to be a relevant injury to the polytraumatised patient. However, literature regarding how far changes in clinical guidelines for pre- and in-hospital trauma management and diagnostic procedures affect the outcome of multiple injured patients with severe chest injury during a long-term observation period is sparse. METHODS: Multiple traumatised patients (age≥16y) documented in the TraumaRegister DGU® (TR-DGU) from January 1st 2005 to December 31st 2014 with severe chest trauma (AIS≥3) were included in this study...

AIM: Periodontists frequently experience inconvenience in accurate assessment and treatment of furcation areas affected by periodontal disease. Furcation involvement (FI) most commonly affects the mandibular molars. Diagnosis of furcation-involved teeth is mainly by the assessment of probing pocket depth, clinical attachment level, furcation entrance probing, and intraoral periapical radiographs. Three-dimensional imaging has provided advantage to the clinician in assessment of bone morphology...

The reliable evaluation of osseous consolidation after hindfoot osteotomy can be difficult. Concomitant hindfoot osteotomies often dictate the advancement of weightbearing, and radiographs are the mainstay imaging tool owing to cost, efficiency, and radiation exposure. Understanding the radiographic parameters that can be used to reliably determine osseous healing is paramount. However, currently, no reliable or validated method is available to determine osseous healing of hindfoot osteotomies in irregular bones of the foot...

In the context of pain diagnostics, several lesions, partially radiolucent and partially opaque, were identified by chance in the mandible and maxilla. On the basis of the characteristic x-ray image, it was assumed to be cemento-osseous dysplasia. At an early stage, this cannot easily be distinguished from apical periodontitis. An incorrect diagnosis could lead to needless endodontic treatment.

CASE DESCRIPTION 2 female red-necked wallabies (Macropus rufogriseus) were evaluated because of sudden-onset mandibular swelling, ptyalism, and hyporexia. CLINICAL FINDINGS Physical examination revealed a mandibular swelling with a fluctuant center in both wallabies. Hematologic analysis revealed leukocytosis with a mature neutrophilia and monocytosis in one wallaby (case 1) and a slight neutrophilia, hyperglobulinemia, and high serum alanine aminotransferase activity in the other (case 2). Cytologic examination of the swelling revealed a uniform population of gram-negative rods in case 1 and neutrophilic inflammation in case 2...

OBJECTIVE: The hip rotation centre (HRC) is an important reference point in cases of total hip arthroplasty (THA). The aim of this study is to investigate the reference points in the Turkish population that enable the identification of the HRC in standard pelvic radiographs. METHODS: The pelvic radiographs of 50 women and 50 men were examined. The mean age was 46.2 (range; 18-91). Patients with deformity of the hip joint and non-standard pelvic radiograph due to hip flexion contracture were excluded from the study...

BACKGROUND: Magnetic resonance imaging (MRI) of the knee is a highly sensitive and specific method for diagnosing acute posterior cruciate ligament (PCL) tears, with a reported accuracy of 96% to 100%. In chronic and revision settings, these injuries may be missed on MRI because of the apparent continuity of nonfunctional PCL fibers. Posterior tibial translation (PTT) of the medial compartment has been identified as a potential secondary finding of PCL tear on routine MRI. Purpose/Hypothesis: The purpose of this study was to evaluate the sensitivity of PTT on MRI associated with PCL injuries and compare it with the sensitivity of a radiologist's MRI interpretation with preoperative posterior knee stress radiographs as the gold standard...

PURPOSE: The optimal coronal alignment is still under debate. However, in most of the studies, alignment was only assessed using radiographs, which are not accurate enough for assessment of tibial and femoral TKA position. The primary purpose of this study was to assess the relationship between coronal TKA alignment using 3D-reconstructed CTs and clinical outcome in patients with preoperative varus in comparison with patients with natural or valgus deformity. It was the hypothesis that neutral limb alignment shows a better outcome after TKA...
