With the increasing popularity of dental implants, the removal of fractured implants has become a major challenge for clinicians. Several tools can be used for the removal of osseointegrated implants; however, few of these have the characteristics of easy control, selective cutting, and rapid healing. In this study, the authors describe a step-by-step technique for the removal of osseointegrated fractured implants via multiple peri-implant osteotomies performed using a piezoelectric device and appropriate inserts. All patients ended with primary wound closure without any soft tissue dehiscence and no healing problems during the postoperative period. As the use of ultrasonic inserts enables precise and selective cuts, piezosurgical implant removal is an attractive alternative to trephine burs or rotary drills.

Adequate intraoperative visualization is mandatory for implant application in pelvic ring injuries. Several fluoroscopic X-ray views are in practical use. The gold standard primary X-ray is the anteroposterior view of the pelvis.

Background: Low-intensity pulsed ultrasound (LIPUS) has been used as an effective noninvasive method for treating fractures and osteoarthrosis, but the application in the field of oral implantation is in its infancy. This study aimed to clarify the effect and mechanism of LIPUS on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and implant osseointegration, and to provide an experimental basis for future clinical applications.
Methods: Dental implants were inserted into Wistar rat femurs, and LIPUS was performed for 4 weeks.

Purpose: A finite element analysis was performed to simulate the biomechanical differences between anterior-posterior (AP) direction and posterior-anterior (PA) direction placement of two cannulated screws in Hoffa fractures.
Methods: Computed tomography images of an healthy male volunteer were used to simulate Letenneur Ⅰ, Ⅱa, Ⅱb, Ⅱc, Ⅲ Hoffa fractures, and two groups of screw internal fixation models were constructed. Two 6.

Purpose: Trauma and orthopaedic (T&O) surgery relies on medical implants and materials, often resulting in metalwork wastage (prosthesis, screws, nails, and plates). This places an economic strain on healthcare services and the environment. Our primary outcome is to quantify the implant wastage across the literature, and secondarily investigate the associated costs in this specialty.

Backgroud: Medial humeral epicondyle fracture is a prevalent type of upper limb fractures in pediatric patients. This study aims to compare the follow-up clinical results and complications in 30 children with medial epicondyle fractures who were treated with either metal screws or absorbable screws at our hospital.
Methods: A retrospective review was conducted on 30 children with medial humeral epicondyle fractures, who were divided into two groups: Metal group (18 children) underwent fixation using metal screws, while Absorbable group (12 children) received absorbable screws between January 2016 and June 2024.
