Study of the morphological difference of upper jaw impressions taken by intra-oral digital scanning and functional impression technique
CONCLUSIONS: Whether using intra-oral digital scanning or functional impression technique, the type of dentition defect was not obviously related to the difference of RMS in distal-extension tissues. In addition, there is positive correlation between the length of distal-extension edentulous area and difference of RMS, which needs further studies with more cases.PMID:36758600 (Source: Shanghai Journal of Stomatology)

Pyrocarbon Disc Interposition Arthroplasty (PyroDisk) for the Treatment of Carpometacarpal Thumb Joint Osteoarthritis
JBJS Essent Surg Tech. 2022 Oct 24;12(4):e21.00034. doi: 10.2106/JBJS.ST.21.00034. eCollection 2022 Oct-Dec.ABSTRACTIn cases of isolated carpometacarpal (CMC) thumb joint osteoarthritis, a hemitrapeziectomy can be performed. To address the risk of subsidence of the first metacarpal, a pyrocarbon disc has been designed as an interposition prosthesis. The disc is made of pyrolytic carbon with the same elastic modulus as cortical bone, making it resistant to wear from surrounding bone. This property contributes to preservation of thumb length and prevents subsidence. The present video article shows the pyrocarbon disc interpo...

Extracorporeal Shock Wave Therapy Improves Nontraumatic Knee Contracture in a Rat Model
CONCLUSION: The findings suggest that ESWT improved joint contracture by inhibiting the TGF-β1/SMADs signaling pathway in rats.CLINICAL RELEVANCE: This work suggests ESWT may be worth exploring in preliminary research in humans to determine whether it may be a treatment option for patients with nontraumatic knee contractures. If the mechanism of ESWT can be confirmed in humans, ESWT might be a therapy for diseases involved in the TGF-β1/SMADs signaling pathway, such as hypertroic scarring and scleroderma.PMID:36724201 | DOI:10.1097/CORR.0000000000002559 (Source: Clinical Orthopaedics and Related Research)

Randomized Controlled Trial Comparing Early Mobilization vs Six Weeks of Immobilization in a Walking Cast Following Total Ankle Replacement
Rehabilitation for patients after total ankle replacement traditionally involves weeks of immobilization in a plaster cast followed by progressive mobilization. In a small randomized trial, we compared teh outcomes of patients who received a 3-component cementless, unconstrained, mobile-bearing prosthesis and were initially immobilised in a plaster cast for 6 weeks to thoese who received the same prosthesis but were allowed to mobilise early. Gait, clinical, patient-reported, and radiologic outcomes were measured. (Source: Journal of Foot and Ankle Surgery)

Secondary osteosarcoma associated with osteofibrous dysplasia: a case report
AbstractSecondary osteosarcoma is a rare complication of primary malignancies and benign bone lesions. There are various types of diseases that cause secondary osteosarcoma. A 15-year-old male presented at our medical center complaining of pain and redness in the right lower leg. He had been diagnosed with osteofibrous dysplasia in the right tibia when he was 2 years old and since then had been followed up. Although he had a pathological fracture of the right tibia at the age of 7, his fracture healed with a plaster cast and did not require surgery. At the time of the patient’s last visit, a radiograph revealed a perio...

On the authenticity of Beethoven ’s skull fragments from the estate of Prof. Dr. Romeo Seligmann
SummaryOn the occasion of the reburial of Beethoven ’s mortal remains in 1863, skull fragments are said to have come into the possession of Prof. Dr. Seligmann, who was present at that time and had conducted scientific investigations. These fragments were inherited in his family and are currently housed in the USA. Their authenticity is doubted by some scientists. On the basis of a plaster cast of Beethoven’s skull kept in the Natural History Museum, Fool’s Tower, in Vienna, the exact topographical position of these skull fragments could be reconstructed and it could be shown that there is no indication that the fra...

Science society lists Earth’s top ‘geoheritage’ sites
The International Union of Geological Sciences last week marked its 60th anniversary by announcing
a list of 100 “geoheritage” sites that have substantially influenced understanding of Earth’s deep history
. The global list, released in collaboration with UNESCO, is meant to foster conservation and tourism. The sites include familiar ones, such as the Grand Canyon’s “great unconformity,” a billion-year gap in the rock record erased by erosion. More exotic examples include limestones in Germany that pres...

Tibiotalocalcaneal Arthrodesis: Comparison of Fixation Methods, Mid-Term Clinical Results
CONCLUSIONS Tibiotalocalcaneal arthrodesis is a surgical procedure reserved exclusively for patients indicated based on strict criteria and should be performed by an experienced team able to cope with potential complications. In the followed-up group of patients, the optimal method of fixation for arthrodesis appeared to be the fixation with a retrograde nail and fibula used as a biological plate. Key words: tibiotalocalcaneal arthrodesis, retrograde nail, lateral ankle plate, ankle instability, ankle arthrosis, biological plate.PMID:36322036 (Source: Acta Chirurgiae Orthopaedicae et Traumatologiae Cechoslovaca)
