Finite element modeling of clavicle fracture fixations: a systematic scoping review.
Med Biol Eng Comput
January 2025
Department of Orthopaedics, School of Medicine, Ruijin Hospital, Shanghai Jiao Tong University, Shanghai, China.
Finite element analysis has become indispensable for biomechanical research on clavicle fractures. This review summarized evidence regarding configurations and applications of finite element analysis in clavicle fracture fixation. Seventeen articles involving 22 clavicles were synthesized from CINAHL, Embase, IEEE Xplore, PubMed, Scopus, and Web of Science databases.

Investigate the impact of antimicrobial photodynamic therapy (aPDT) using different photosensitizers (PSs) such as indocyanine green (IG), curcumin (CC), and methylene blue (MB), with or without intracanal application of calcium hydroxide (CH), on the push-out bond strength of glass-fiber posts (GFPs) to intraradicular dentin, the chemical composition of the root substrate, and the sealing of the adhesive interface across different thirds of intraradicular dentin. A total of 112 bovine teeth underwent biomechanical preparation and were divided into eight experimental groups (n = 14 each): Negative control with deionized water; positive control with deionized water + CH; IG group with indocyanine green and infrared laser; IG + CH group; CC group with curcumin and blue LED; CC + CH group; MB group with methylene blue and red laser; and MB + CH group. The push-out bond strength was measured using a universal testing machine (n = 8), and scanning electron microscopy characterized the fracture patterns.

Osteoporos Int
January 2025
Department of Orthopaedic Surgery, Wakayama Medical University, 811-1 Kimiidera, Wakayama, 641-8510, Japan.
Unlabelled: Metaphyseal comminution in distal radius fracture (DRF) cases might indicate severe osteoporosis. The patients with DRFs and metaphyseal comminution showed 5.2-fold increased secondary fractures compared with those receiving combination osteoporosis therapy.

Department of Orthopedics and Traumatology, Yıldırım Beyazıt University, Bilkent City Hospital, Ankara, Türkiye.
Objective: This study aimed to investigate the e!ect of arthroscopic Bankart repair (ABR) alone and ABR with an additional remplissage procedure on joint range of motion and functional results in patients with anterior shoulder instability.
Methods: This retrospective study included patients treated 1 year ago with either ABR alone or the ABR additional remplissage procedure. The Bankart lesion was determined by magnetic resonance imaging, and the amount of glenoid bone loss was determined by computed tomography.
Biomechanical comparison of locking femoral neck plate versus cannulated screws with or without a medial buttress plate in Pauwels type 3 femoral neck fractures.
Acta Orthop Traumatol Turc
December 2024
Department of Orthopaedics and Traumatology, Izmir Katip Celebi University, Ataturk Training and Research Hospital, Izmir, Türkiye.
Objective: The aim of this study was to evaluate whether the locking femoral neck plate (LFNP) can be an alternative fixation method to the cannulated screws with a medial buttress plate. For this purpose, we compared biomechanically the LFNP and cannulated screws with or without a medial buttress plate in Pauwels type 3 femoral neck fractures.
Methods: A vertical fracture model was created at an 80-degree angle to the femoral neck in 28 synthetic bone models.
