X-ray therapy of chronic arthritis, considered by Appel rath (according to the ref. Zentr. F. Ch., 1926, No. 12) in the plane of the historical review leaves a very favorable impression: in many cases, a significant subjective improvement and increase in the range of motion of the joints is obtained.

Abstract X-Ray Reconstruction of Moving Morphology (XROMM), though traditionally used for studies of in vivo skeletal kinematics, can also be used to precisely and accurately measure ex vivo range of motion from cadaveric manipulations. The workflow for these studies is holistically similar to the in vivo XROMM workflow, but presents several unique challenges. This paper aims to serve as a practical guide by walking through each step of the ex vivo XROMM process: how to acquire and prepare cadaveric specimens, how to manipulate specimens to collect X-ray data, and how to use these data to compute joint rotational mobility. Along the way, it offers recommendations for best practices and for avoiding common pitfalls to ensure a successful study.

We examined tRNA flexibility using a combination of steered and unbiased molecular dynamics simulations. Using Maxwell's demon algorithm, molecular dynamics was used to steer X-ray structure data toward that from an alternative state obtained from cryogenic-electron microscopy density maps. Thus, we were able to fit X-ray structures of tRNA onto cryogenic-electron microscopy density maps for hybrid states of tRNA. Additionally, we employed both Maxwell's demon molecular dynamics simulations and unbiased simulation methods to identify possible ribosome-tRNA contact areas where the ribosome may discriminate tRNAs during translation. Herein, we collected >500 ns of simulation data to assess the global range of motion for tRNAs. Biased simulations can be used to steer between known conformational stop points, while unbiased simulations allow for a general testing of conformational space previously unexplored. The unbiased molecular dynamics data describes the global conformational changes of tRNA on a sub-microsecond time scale for comparison with steered data. Additionally, the unbiased molecular dynamics data was used to identify putative contacts between tRNA and the ribosome during the accommodation step of translation. We found that the primary contact regions were H71 and H92 of the 50S subunit and ribosomal proteins L14 and L16.

The clinical and radiological outcomes of 25 surgically treated fractures of the proximal third of the fifth metacarpal were retrospectively analysed. Many different methods of osteosynthesis were used. At follow-up after a mean of 3.3 years, 15 of 25 patients had no pain. Most patients regained a nearly full range of motion in the adjacent joints and more than 90% of the contralateral grip strength. X-ray signs of degenerative arthritis in the metacarpohamate joint were observed in 10 of 25 patients. Pain was found to be directly correlated with the presence of degenerative changes.

Abstract Background The aim of this study is to evaluate the clinical and imaging outcome of pediatric supracondylar humerus fractures with bone fragments on X ray film after closed reduction and percutaneous pin fixation.Methods A retrospective review of 12 children with fragments on image after closed reduction treatment for displaced humeral supracondylar fractures (Gartland III). Primary radiographic assessment included the outcome of the fragments, post-operative Baumann angle, Carrying angle and loss of reduction. The clinical outcome included elbow range of motion, Flynn grade and other complications.Results Totally there were 460 cases of pediatric supracondylar humerus fractures (2-14 years old) treated in our center from January 2015 to January 2018, and 12 (2.6%) of the patients with bone fragments on postoperative X ray film were included. All 12 patients had bone fragments union or absorbed at 1 year after operation with good radiographic and clinical outcome. The mean Baumann angle was 15.5±4.3°, and the mean Carrying angle was 11.2±2.8°. All patients had a normal elbow range of motion, 10 patients obtained an excellent result, and 2 patients were good According to Flynn criteria. Conclusions We have good results for closed reduction and percutaneous pin fixation treatments in 12 pediatric supracondylar humerus fractures with bone fragments. The fragments were mainly absorbed or union to humerus in one year after surgery.

Abstract The AMA Guides to the Evaluation of Permanent Impairment, Fourth Edition, includes two methods of evaluating low back impairment following injury, the Diagnosis-related estimates (DRE) method and the Range of Motion (ROM) method. The DRE method should be used first, and the ROM method should be used only when the patient's injury is difficult to categorize or when two examiners disagree about how to categorize a patient. The final rating always comes from the DRE category, never from the ROM method. Two groups of findings help determine into which DRE category to place the patient: First are structural inclusions (eg, fracture patterns on an x-ray) that are objective and automatically place a patient into a DRE category. Second are differentiators such as guarding, loss of reflexes, or loss of bowel or bladder control. In addition, unlisted objective findings may help categorize a patient but may require interpretation; examples include muscle spasm, nonverifiable root pain, anatomical numbness, anatomical weakness, and straight-leg raising. This article discusses the interpretation of sometimes partially subjective findings, thus objectifying them: guarding; muscle spasm; dysmetria; nonverifiable root pain; loss of reflexes; atrophy; straight-leg raising; anatomical numbness; weakness; EMG; loss of motion segment integrity; loss of bowel or bladder control, bladder studies; and range of motion.

Radiographic imaging for the diagnosis of caries lesions has been a supplement to clinical examination for approximately a century. Various methods, and particularly X-ray receptors, have been developed over the years, and computer systems have focused on aiding the dentist in the detection of lesions and in estimating lesion depth. The present historical review has sampled accuracy ex vivo studies and clinical studies on radiographic caries diagnosis that have compared two or more receptors for capturing the image. The epochs of film radiography, xeroradiography, digital intraoral radiography, panoramic radiography and other extraoral methods, TACT analysis, cone-beam CT and artificial intelligence systems aiding in decision-making are reviewed. The author of this review (43 years in academia) has been involved in caries research and contributed to the literature in all the mentioned epochs.
