Diaphyseal fractures of the femur and tibia in adults are mostly treated surgically, usually by means of intramedullary locked-nail osteosynthesis. Some comminuted and/or highly deviated shaft fractures may present a veritable technical challenge. Fracture (or orthopedic) tables, which enable vertical, horizontal and rotational instrumental stabilization of the limb, greatly facilitate reduction and implant placement maneuvers and are widely used by orthopedic surgeons. Humeral shaft fractures are mostly treated nonsurgically. However, some cases with indications that are well defined in the literature require surgical treatment. They can be fixed by means of plates or intramedullary nails, using anterograde or retrograde routes. In the humerus, fracture reduction and limb stabilization maneuvers for implantation of intramedullary nails are done manually, usually by two assistants. Because muscle fatigue may occur, this option may be less efficient. The aim of this paper is to present an external upper-limb traction device for use in anterograde intramedullary locked-nail osteosynthesis of humeral shaft fractures that enables vertical, horizontal and rotational stabilization of the upper limb, in a manner similar to the device used for the lower limbs. The device is portable, of simple construction, and can be installed on any operating table equipped with side rails. It was used for surgical treatment of 29 humeral shaft fractures using an anterograde locked intramedullary nail. Our experience was extremely positive. We did not have any complications relating to its use and we believe that it notably facilitated the surgical procedures.

Background: The incidence rate of subsequent refracture after removal of the implant in mid-shaft clavicle fracture patients is relatively high. This can lead to additional medical costs and cause doctor-patient dispute. This study tries to introduce a new method to predict the refracture risk of the clavicle after hardware removal.

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.

Background: The fracture of an endodontic instrument within the root canal system can occur during root canal therapy, complicating thorough cleaning and shaping. Consequently, managing the broken fragment becomes crucial.
Methods: Eighty Nickel-titanium (NiTi) #20 K-files (Mani, Tochigi, Japan) were cut 8 mm from the tip, fixed into a corkboard, and classified into five groups (n = 14 each).

Aims: The "2 to 10% strain rule" for fracture healing has been widely interpreted to mean that interfragmentary strain greater than 10% predisposes a fracture to nonunion. This interpretation focuses on the gap-closing strain (axial micromotion divided by gap size), ignoring the region around the gap where osteogenesis typically initiates. The aim of this study was to measure gap-closing and 3D interfragmentary strains in plated ovine osteotomies and associate local strain conditions with callus mineralization.

Introduction: Arterio-enteric fistula is one of the extremely rare complications of penetrating trauma.
Case Presentation: A 27-year-old male presented to the emergency department with a gunshot to the right buttock. Initial assessments revealed a left femoral shaft fracture, the right buttock as the bullet inlet and the medial portion of the left thigh as an outlet, with no other significant findings.
