Influence of phosphor plate–based radiographic image specifications on fractal analysis of alveolar bone
ConclusionsFractal analysis of alveolar bone obtained from PSP plate–based intraoral radiographic images is influenced by spatial resolution and some digital enhancement filters; therefore, for FD comparison purposes, images should have the same specifications.
Authors: Tsai YC, Lee HL, Kuo CC, Chen CY, Hsieh KL, Wu MH, Wen YC, Yu HW, Hsu FC, Tsai JT, Chiou JF Abstract Background: Magnetic resonance-guided focused ultrasound surgery (MRgFUS) is an alternative local therapy for patients with painful bone metastasis. However, little is known about the prognostic and predictive factors of MRgFUS in treating bone metastasis. Materials and methods: This retrospective study analyzed the performance status, treated site, pretreatment pain score, pretreatment tumor volume and lesion coverage volume factor (CVF) of 31 patients who underwent MRgFUS. A numerical rating scale for pai...
CONCLUSIONS: The results emphasize the need for a cautious approach to using dental CBCT. Imaging only when the clinical indications are clear, accompanied with the appropriate radiographic techniques and the optimum imaging protocol, will help reduce radiation dose to patients.

CONCLUSIONS: Pelvic fracture MRI should be performed primarily in elderly female patients without adequate trauma. In patients with adequate trauma, MRI is of low value, especially as MRI diagnostics are performed with delay, resulting in later surgery. PMID: 31533165 [PubMed - as supplied by publisher]
Conclusions3D optical imaging of patients with pectus excavatum is emerging as an alternative method to assess HIs without the use of ionizing radiation. Additional studies will focus on volumetric quantification of chest wall deformities, using the 3D capabilities of this technology.
ConclusionsAnatomic ACL reconstruction could restore not only the normal anterior knee laxity, but also the normal tibiofemoral relationship even under an anterior tibial load.
CONCLUSION: Three-dimensional computed tomography reconstruction, as well as the hollow appearance of a tubular structure after removal of a central catheter may help differentiate a fibroblastic sheath from a retained catheter fragment. Accurate surgical notes mentioning the length of the catheter at implant and explant are also of paramount importance. PMID: 31526092 [PubMed - as supplied by publisher]
The objective of this long-term study was to evaluate radiographic healing in cone-beam computed tomographic (CBCT) scans taken 1 and 5 years after apical surgery.
Conclusion: Syndesmotic screw removal and weight bearing may be advantageous to achieve final anatomic reduction of the syndesmosis. Syndesmotic screw removal at appropriate time could not improve foot functional outcomes; however, more studies with the larger sample size are required to confirm the results of the study.

DiscussionUsing the navigation system, combined anteversion is made near the target angle in isolated acetabular revision surgery and more accurately than manual implantation. These results should be considered as preliminary since this is a limited cohort, but it brings new knowledge in navigation considering the very limited number of series using of navigation in isolated cup revision of total hip arthroplasty. In addition this is the first study to investigate combined cup and stem anteversion in isolated acetabular revision. The use of CT-scan is helpful to diagnose error in stem anteversion and to adapt the orientati...
Abstract OBJECTIVE: Stabilizing sacral fragility fractures without radiation exposure to the surgical team. INDICATIONS: Non-displaced or minimally displaced unilateral or bilateral transalar, transforaminal or central sacral fractures in weak and osteoporotic bone. CONTRAINDICATIONS: Displaced or highly unstable sacral fractures. Patients under therapeutic anticoagulation. Patients needing fast track orthopedic surgery. SURGICAL TECHNIQUE: Prone position. Reference clamp installation on posterior iliac crest. Initial 3D scan of posterior pelvic ring. Image-guided virtual determination of 2-3 i...
