This clinical photograph displays an ex vivo femoral shaft undergoing internal fixation for a simple oblique fracture, serving as an educational example of orthopedic osteosynthesis. The primary stabilization is achieved using a shiny, metallic 8-hole Dynamic Compression Plate (DCP) contoured to the lateral aspect of the bone. The plate is secured with six bicortical screws positioned across the proximal and distal segments, acting in a neutralization function. Notably, an independent lag screw is placed perpendicularly across the fracture line to provide dynamic compression and enhance mechanical stability. The bone specimen exhibits a smooth cortical surface with visible reddish staining near the epiphyses, indicating the presence of vascularized tissue or residual soft matter. The arrangement demonstrates key principles of fracture management, including anatomical reduction and stable internal fixation to facilitate secondary bone healing. This image is relevant for surgical training and biomechanical study of plate-and-screw constructs in long bone fractures.

This clinical photograph displays a close-up of a Limited Contact Dynamic Compression Plate (LC-DCP) construct used in an orthopedic biomechanical study of femoral fracture fixation. The image illustrates a procedural failure analysis of an internal fixation system. A significant osteotomy gap is visible between the proximal and distal bone segments, showing asymmetrical widening at the cranial aspect and narrowing at the caudal aspect, indicating a cranial tilt and rotational displacement of the distal fragment. Metal screws are numbered for testing, with screw No. 5 specifically highlighting mechanical failure. The black marker lines on the screw head and the plate surface, which were originally aligned, show a clear deviation. This misalignment serves as visual confirmation of screw loosening and rotation within the plate hole during axial loading. The image is used to demonstrate the structural weakness of bone-plate constructs under compression and to identify signs of hardware migration in orthopedic surgery.

This diagnostic image consists of two radiographic views (anteroposterior, A; lateral, B) of a right forearm, three months post-operative. The radiographs demonstrate surgical internal fixation of both the radius and ulna using metallic compression plates and screws. A dynamic compression plate (DCP) is visible on the distal-to-mid shaft of the radius, secured with five cortical screws. A similar, shorter plate is affixed to the ulna, secured with five screws. Black arrows indicate the primary fracture sites on both bones. These sites show evidence of progressive fracture union characterized by bridging callus formation and increased radio-opacity, indicating biological consolidation. The surrounding soft tissues appear unremarkable, and the alignment of the radial and ulnar shafts is well-maintained. This image is an educational example of orthopedic fracture management using open reduction and internal fixation (ORIF) and the assessment of secondary bone healing in a clinical follow-up setting.

An anteroposterior (AP) view X-ray of the right distal femur demonstrating internal fixation and surrounding pathology. A radiopaque dynamic compression plate (DCP) is visible on the lateral aspect of the femoral shaft, secured by multiple orthopedic screws. In the adjacent soft tissues, there is a large, ill-defined area of increased radiolucency (hyperlucency) indicated by two red horizontal arrows, suggesting a significant soft tissue mass, fluid collection, or abscess. The distal femur shows signs of previous fracture healing or remodeling around the hardware. This diagnostic image is significant for evaluating post-surgical complications, such as infection or tumor formation (e.g., plasmablastic lymphoma as suggested by context) in the setting of chronic orthopedic implants.

A close-up clinical photograph showing an intraoperative surgical field during orthopedic internal fixation for a periprosthetic fracture. The focal point is a metallic LOQTEQ® Variable Angle (VA) Periprosthetic Plate system secured to a bone. The central locking compression plate (LCP) features multiple circular screw holes. Adherent to the lateral margins of the main plate are specialized attachable hinges designed for variable-angle screw placement. These hinges contain inserted locking screws with color-coded blue and gold heads. A freehand drill guide with a 2.7 mm diameter marking is actively positioned within one of the hinge openings, demonstrating the technique for drilling a pilot hole at a specific angle to bypass existing intramedullary prosthetic hardware. The surgical site displays exposed muscle and soft tissue with moderate hemarthrosis/bleeding typical of open reduction and internal fixation (ORIF) procedures. This image illustrates the application of modular plating systems in complex fracture management where standard monocortical or biaxial screw trajectories are obstructed by an existing implant.

An intraoperative clinical photograph demonstrating an open reduction and internal fixation (ORIF) procedure for a distal femoral fracture. The image shows a locking compression plate (LCP) originally designed for the proximal tibia being utilized in an off-label, inverted orientation to provide anatomical fixation for the medial femoral condyle. The metallic plate is contoured to the bone surface and secured with a combination of cortical and locking screws. Key visible features include the exposed bone and soft tissue of the right knee joint through a medial parapatellar approach, with surgical retractors reflecting the tissue. The educational focus of this image is on unconventional hardware application and surgical salvage techniques for complex intra-articular fractures (AO classification: 33-B2.1). This material is relevant for orthopedic surgery residents and trauma surgeons specializing in lower limb reconstruction.

Anteroposterior (AP) x-ray of the shoulder demonstrating a proximal humerus fracture treated with internal fixation. A metallic locking compression plate (LCP) is positioned on the lateral aspect of the humeral shaft, extending superiorly to the greater tuberosity. The construct features multiple locking screws: proximal screws are oriented at varying angles to support the humeral head subchondral bone, while distal screws are inserted perpendicularly into the humeral diaphysis. Educational annotations in red illustrate the methodology for measuring Humeral Head Height (HHH). Two parallel horizontal lines are drawn: the superior line identifies the highest point of the humeral head articular surface, and the inferior line aligns with the top edge of the orthopedic plate. A double-headed vertical arrow indicates the distance between these lines, used clinically to monitor for postoperative loss of fixation or subsidence of the humeral head. The image provides a clear demonstration of orthopedic implant positioning and radiographic assessment parameters for proximal humeral fractures.

This diagnostic image is an early postoperative anteroposterior (AP) X-ray of the left shoulder. It demonstrates surgical fixation of a scapular spine fracture or pseudoarthrosis. A radiopaque metallic Locking Compression Plate (LCP) is visible, anatomically contoured and positioned along the spine of the scapula. The plate is secured with multiple cortical screws providing internal fixation and compression across the bony disruption. Key anatomical structures visible include the scapula (acromion and spine), the proximal humerus, the clavicle, and the upper rib cage. Radio-dense surgical staples or sutures are also visible in the overlying soft tissue, indicating recent wound closure. The image illustrates orthopedic management for complex scapular injuries and the use of internal fixation to promote bony union in cases of non-union or pseudoarthrosis. The humeral head is noted in the glenohumeral joint, and the hardware appears stable in this early follow-up phase.
