Purpose: We aim to determine whether end-fire probe orientation (and therefore image orientation and biopsy needle direction) during transrectal ultrasonography-guided prostate biopsy has an effect on the prostate cancer (PCa) detection rate, the number of positive biopsy cores, the proportion of diseased tissue in the samples obtained, and the Gleason score. We compared two different axial image protocols and a sagittal image protocol for PCa yield. We hypothesize that axial probe methods direct more of the biopsy needle through the peripheral zone, the principal site for PCa, and therefore improve PCa yield.
Patients And Materials: A total of 441 patients underwent systematic 12-core biopsy using three different methods by six radiologists at our institution. An axial method using probe angulation, an axial method using probe rotation, and a sagittal method were compared.
Results: The axial-angulation method was used in 166 men, the axial-rotation method was used in 125 men, and the sagittal method was used in 150 men. Overall, 58.3% had PCa detected. Axial-rotation techniques showed a 17% greater PCa yield and significantly increased the number of positive biopsy cores relative to the sagittal method (P < 0.001) for all patients and for those with a prostate-specific antigen level <10 ng/mL. Of those with PCa, the number of positive cores, proportion of diseased tissue, and Gleason score were also significantly elevated using this technique (P < 0.05).
Conclusion: This study suggests that axial techniques have the potential to increase carcinoma yield and Gleason score, through a greater yield in positive core number and proportion of diseased tissue in the samples obtained.

Introduction: The plantar plate, also called the plantar ligament, is a fibrocartilaginous structure found in the metatarsophalangeal (MTP) and interphalangeal (IP) joints. Our study aimed to evaluate the role of magnetic resonance imaging (MRI) performed with the patient in the standard position or with joint hyperextension (the "stress test", ST) in the study of plantar plate (PP) disease that involves metatarsophalangeal joints.
Materials And Methods: All patients underwent forefoot MRI (Atroscan C, Esaote, Genoa, Italy), operating at 0.

Purpose: This study aimed to quantitatively analyze temporomandibular joint (TMJ) space volume changes before and after bilateral sagittal split ramus osteotomy (BSSRO) with intended manual condyle positioning in patients with severe facial asymmetry.
Methods: A retrospective study was conducted, including 20 patients with facial asymmetry (menton deviation >8 mm) who underwent BSSRO with intended manual condyle positioning at a single institution. Cone beam computed tomography (CBCT) images were obtained preoperatively (T0), 2 days postoperatively (T1), and 6 months postoperatively (T2).

Background: Unrestricted kinematic alignment (uKA) in total knee arthroplasty (TKA) has the theoretical advantage of reproducing patients' constitutional alignment and restoring the pre-arthritic joint line position and obliquity. However, modifications of the original uKA technique have been proposed due to the potential risk of mechanical failure and instability. Given the significant variability in soft tissue behavior within the same bony morphology group, uKA pure knee resurfacing could be occasionally detrimental.

Objective: To confirm the effect of surgery on spinal column biomechanics and to provide theoretical support for the advantages and disadvantages of different surgical methods and their clinical efficacy.
Methods: 33 continuous patients with no significant difference in risk factors related to the mechanical complications were enrolled in this retrospective study. Sagittal parameters were measured in the pre-, post-operative and following-up lateral radiograph of spine.

Background: Anterior column realignment (ACR), using a lateral lumbar or thoracic interbody fusion (LLIF) approach to release the anterior longitudinal ligament (ALL), is a powerful technique to increase segmental lordosis. We here report our experience with the use of expandible LLIF cages for ACR.
Methods: Retrospective, single-center observational cohort study including consecutive patients treated by LLIF using an expandible interbody implant.
