Analysis and quantification of bone healing after open wedge high tibial osteotomy. Wien Klin Wochenschr. 2019 Sep 09;: Authors: Nemecek E, Chiari C, Valentinitsch A, Kainberger F, Hobusch G, Kolb A, Hirtler L, Trost C, Vukicevic S, Windhager R Abstract BACKGROUND: The aim of this study was to analyze radiographic imaging techniques and to quantify bone ossification in the osteotomy gap after high tibial osteotomy. MATERIAL AND METHODS: Study phase 1: high tibial osteotomy was performed on six lower extremities of human body donors and experimental X‑rays and computed tomography (CT) scans were applied. Different techniques were evaluated by three specialists for best representation of the osteotomy gap. Study phase 2: optimized radiological techniques were used for follow-up on 12 patients. The radiographs were examined by 3 specialists measuring 10 different parameters. The CT scans were analyzed with semiautomatic computer software for quantification of bone ossification. RESULTS: The osteotomy gap was best represented in 30° of flexion in the knee and 20° internal rotation of the leg. There were significant changes of the medial width over time (p

This study was aimed to estimate the length of the MIC in the interforaminal safe zone, to analyse its course in relation to the lingual and the buccal cortical plates of the mandible using cone beam computed tomography (CBCT) scans and to relate the above findings to age, gender, dental status and Malaysian races.MethodsRetrospective analysis of 100 CBCT scans (n = 200) was performed on both sides of the mandible. Cross-sectional and panoramic images were reconstructed. The length of the MIC and the horizontal distances between the MIC and the buccal and the lingual cortical plates were measured at the three...

ConclusionsThe carotid bifurcation is in close proximity to various calcified anatomical structures. This should be taken into account when diagnosing CCPs in panoramic radiographs (PRs). In the coronal view, CCPs and the cervical spine are often superimposed; thus, coronal images are not recommended for confirmation of putative carotid calcifications diagnosed on PRs.

Conclusions: The Schneiderian membrane thickness was positively and highly associated with gingival biotype. The gingival biotype and arch form had significant effect on Schneiderian membrane thickness and can provide valuable clinical information on Schneiderian membrane thickness preoperatively for implant placement and sinus lift procedures.

This study found that The Canary System was more accurate than Bitewing Radiographs and Cone Beam CT in detecting caries on the gingival floor beneath composite restorations.  The sensitivity and specificity data (table on the right) indicates that The Canary System could find 89% of the caries where the other devices found 40% of the lesions.One of the major reasons for replacing restorations is tooth decay that develops around the edges of the filling.  This study found that “Radiographs though valuable in the detection of advanced caries lesions, are less sensitive for early or recurrent lesions under re...

This study compares the long-term functional, radiographic, and computed tomography (CT) scan outcomes and implant survivorship of ceramic-on-ceramic total hip arthroplasty (C-O-C THA) and ceramic-on-highly X-linked polyethylene total hip arthroplasty (C-O-HXLPE THA) in the same patients.

Discussion Foreign bodies are common problems for young children particularly ages 2-4 years who will mouth many objects and aspirate or swallow them. Children will also place foreign objects in other body orifices such as ears or noses. It is also not uncommon that young girls will inadvertently have toilet paper caught in the vaginal area during hygiene. Many of these foreign bodies may work their way out naturally not causing any problems, or may come to attention later because of chronic problems such as a foul-smell or discharge. Older children may tell adults that they have placed a foreign body in an orifice and thu...

BackgroundChronic rhinosinusitis (CRS) is associated with bronchiectasis; however, this relationship has not been well studied in the United States (US) population. In this work we aimed to determine the prevalence of CRS among patients with bronchiectasis affiliated with a US tertiary medical center and identify which comorbid diseases are associated with the presence of CRS in patients with bronchiectasis.MethodsThis was a retrospective cohort study in which data were obtained from a large database warehouse at a tertiary care center. Patients with bronchiectasis were identified from 2007 to 2017 using diagnosis codes fr...

This report describes 2 clinical cases of middle-aged women with COF. Clinical examination revealed palatal mucosal depression; additionally, oral examination, as well as panoramic radiographs, intraoral radiographs, and computed tomography scans, revealed severe root resorption. This report highlights the clinical and radiological imaging features of COF, with the goal of enabling straightforward differential diagnosis of the lesion by the clinician and thereby appropriate treatment of the patient.

The purpose of this report is to present a rare case of metastatic breast carcinoma to bilateral mandibular ramus regions. The present case report is about a 40-year-old female patient with the complaints of a paresthesia in the right mandibular area of the last month duration. She was referred to our department by her oncologist with the differential diagnosis of osteonecrosis or metastasis. She h...

CONCLUSION: In this study, 20.5% of hips classified as ARCO stage I or II on simple radiography were found to be ARCO stage III on CT imaging. When a joint-preserving treatment is considered for early stage ONFH, CT examination is necessary for more precise staging of the disease. PMID: 31571188 [PubMed - as supplied by publisher]
