Dimensions: Available in several diameters (e.g., 7, 8, 9 mm) and lengths (e.g., 190 to 310 mm, varying by diameter) to accommodate different anatomies and fracture types.

Insertion: Can be introduced antegrade or retrograde, depending on the location and type of fracture.

Stability: The design and locking options are designed to provide robust fixation and axial stability, promoting bone healing.

The characteristics of a compression screw, such as the DHS/DCS lag screw, are as follows:

Material: Generally made of surgical-grade stainless steel.

Design: Consists of a thread and a head, with a specific design to allow dynamic compression.

Function: Used to stabilize fractures, particularly proximal femoral fractures (dynamic hip screw or DHS) or distal femoral fractures (dynamic condylar screw or DCS), by allowing controlled sliding of the screw within a plate to promote compression at the fracture site.

Use: Designed to be inserted into bone, such as the femoral neck, and combined with a plate (e.g., DHS or DCS plate) that is secured along the bone.

Sterility: Screws intended for surgical use are sterile.

Dimensions: Available in various lengths and thread diameters to accommodate anatomical needs and fracture types.

The features of the Volary Locking Plate for Distal Radius Fractures include:

Material and Strength: These plates are generally made of biocompatible materials such as titanium, providing adequate strength and durability for bone fixation.

Multiple and Specific Holes: The plate features locking holes for angle-stable screws and oval holes for cortical screws, allowing for precise positioning and adjustments.

Surgical Use: Primarily used for the surgical treatment of complex intra-articular and extra-articular fractures of the distal radius, as well as for osteotomies.

Identification Markings: The plate may include markings such as “R” to indicate the side (right) and model/serial numbers, such as “Deffron 3 Hole ST240.003” shown in the image.

Features of proximal radius security locking plates for the radial head rim include:

Material: Typically made of medical-grade stainless steel or titanium, ensuring biocompatibility and strength.

Anatomical Design: Specifically designed to conform to the curvature and anatomy of the proximal radius, providing an optimal fit.

Fixed or Variable Angle Locking: Provides stable fixation and prevents radial head collapse. Screws can be placed at fixed or variable angles for improved stability of the bone fragments.

Multi-Angle Fixation: Provides improved angular fixation of the radial head proximally.

Low Profile: Designed to minimize soft tissue irritation with beveled edges, rounded and polished surfaces, and countersunk screws.

Screw Holes: Often include locking holes for fixed-angle screws and combination holes for compression and locking screws.

Indications: Primarily used for the treatment of proximal radius fractures, including those affecting the radial head.

The characteristics of a Y-shaped reconstruction plate generally include the following:

Shape and Design: It is designed in a “Y” shape to accommodate specific anatomical configurations, often used for complex fractures or osteotomies requiring fixation in multiple directions, such as the calcaneus or pelvis.

Material: Made of high-quality stainless steel or titanium, providing biocompatibility and corrosion resistance.

Screw Holes: Multiple holes along the plate legs for the insertion of fixation screws, providing angular stability or compression, depending on the type of screw used (locking or non-locking).

Dimensions: Can vary in thickness, width, and hole spacing to accommodate different bone sizes and fracture types. For example, a Y-shaped reconstruction plate might be 2.0 mm thick, 9.6 mm wide, and have a 12.0 mm hole spacing, and be designed for 3.5 mm screws.

Applications: Used for internal fixation of fractures, osteotomies, or arthrodesis in areas such as the calcaneus, pelvis (especially the acetabulum), or distal fibula.

The Pelvic Straight Locked Plate features are as follows:

Material: 316L / 316LVM stainless steel / Titanium.

Dimensions: Available in various sizes, from 2 to 20 holes (with a difference of one hole between each size).

Profile: 10.0 mm x 3.0 mm.

Hole spacing: 13.0 mm.

Screws: Compatible with 4.0 mm screws.

Use: Suitable for the pelvic ring, the medial and lateral aspects of the ilium, and posterior and anterior wall fractures.

Features of the SuperCable® Iso-Elastic™ multifilament polymer cerclage system, shown in the image, include:

Iso-elasticity: Allows long-term dynamic compressive loading on bone fragments, promoting better healing and greater construct strength.

Superior fatigue resistance: Compared to metal cables and wires, reducing complications related to fracture.

Polymer cable: Eliminates metal contact with metal implants, the risk of sharps injuries, and glove tears.

Unique “no-crimp” locking mechanism: Allows for easy cable tightening, saving time in the operating room and reducing the number of cables required.

Biocompatibility: The cable is composed of UHMWPE strands braided over a nylon core, and the clasp components are made of titanium alloy.

Flexible Design: The polymer cable is flexible and has high fatigue and tensile strength.

Larger Footprint: The double-stranded cable can minimize penetration into soft bone.

Ease of Use: The polymer cable is easy to handle and can be quickly cut with a scalpel for rapid reinsertion in an emergency.

A femoral intramedullary nail is an orthopedic implant used for the fixation of femoral fractures, particularly femoral neck fractures.

Here are the main characteristics of this implant:
Implant Type: Femoral intramedullary nail, often referred to as the Femoral Neck Fixation System (FNS).

Targeted Joint/Bone: Femur, specifically the femoral neck for fractures.

Fixation Mechanism: It provides proximal and distal fixation using screws that pass through the nail and anchor into the bone.

Material: Made of titanium, a biocompatible and strong material.

Stability: Designed to provide improved angular and rotational stability, with the goal of reducing reoperations related to fixation complications.

The intramedullary nails shown, whether long or short, are orthopedic implants used to stabilize long bone fractures. Their main characteristics are:

Materials: They are generally made of titanium alloy or surgical stainless steel, biocompatible materials resistant to corrosion and mechanical stress.

Design:
Long nails: Designed for diaphyseal (central portion) fractures of long bones, such as the femur or tibia.

Short nails: Used for proximal fractures, such as those of the proximal humerus or proximal femur (subtrochanteric or intertrochanteric fractures).

Locking: They are equipped with locking screws (e.g., 4.5 mm) that pass through the bone and the nail to ensure stable fixation of the fracture and prevent rotation or shortening.

Functionality:
Cannulated: Many nails are cannulated, allowing for the insertion of a guide wire during surgery for precise positioning.

Indications: Their use varies depending on the patient’s age, the site, and the type of fracture, including diaphyseal and metaphyseal fractures, and nonunions.
