Calcaneal Plates Ensuring Effective Fixation for Calcaneal Fractures

Geasure Calcaneal Bone Plates: Addressing Clinical Challenges in Calcaneal Fracture Treatment

I. Clinical Scenarios: Practical Challenges and Needs in Calcaneal Fracture Treatment

(I) Specificity and Treatment Difficulties of Calcaneal Fractures

As a core weight-bearing part of the human body, the calcaneus has an irregular shape and abundant cancellous bone. Once fractured (such as Sanders type II-IV), it often faces multiple challenges: precise reduction of the articular surface is difficult to control, which may leave hidden dangers of post-traumatic arthritis; the fixation stability of comminuted fracture fragments is insufficient, and displacement may occur after surgery; traditional fixation methods require large incisions, increasing the risk of soft tissue damage and infection. For doctors, instruments that can adapt to the anatomical shape of the calcaneus and provide stable fixation are needed; for patients, they expect to recover walking function faster after surgery and reduce long-term pain.

(II) Room for Improvement in Traditional Fixation Schemes

The ordinary bone plates commonly used in clinical practice in the past are mostly standardized designs, which are difficult to fully fit the lateral wall surface of the calcaneus of different patients, possibly leading to uneven distribution of fixation stress; some bone plates have a single screw hole position, which cannot effectively support scattered comminuted fracture fragments; if the mechanical compatibility between the metal bone plate and bone is poor, it may also cause stress shielding and affect fracture healing. These problems all require more targeted calcaneal fixation instruments to address.

II. Geasure Medical: A Solution Provider Specializing in Orthopedic Trauma

(I) Enterprise Positioning: From "Instrument Manufacturing" to "Responder to Clinical Problems"

Geasure Medical is not merely an orthopedic instrument manufacturer, but an innovative enterprise oriented towards "solving practical clinical pain points". Headquartered in Changzhou West Taihu Lake Science and Technology Industrial Park, it has accumulated years of technical experience in the fields of spine and traumatic orthopedics. Its core team includes both clinical consultants familiar with the anatomical characteristics of the calcaneus and engineers specializing in implant design, always focusing on "how to make calcaneal fracture fixation more precise and safer" in R&D and production.

(II) Three Core Capabilities Supporting the R&D of Calcaneal Bone Plates

① Clinical Collaborative R&D: Aligning Design with Surgical Reality

Demand Mining: Cooperate with orthopedics departments of multiple top three hospitals, collect hundreds of calcaneal fracture surgical cases, and sort out three core needs: "reduction guidance", "comminuted fragment fixation", and "minimally invasive implantation";

Design Verification: Every curved surface and screw hole of the calcaneal bone plate undergoes simulated implantation tests on 3D printed personalized calcaneal models to ensure fit and operational convenience;

Compliance Endorsement: Relying on the enterprise's existing FDA 510(k) certification (such as thoracolumbar-sacral pedicle screw system K222031), CE certification, and ISO 13485 system, the R&D and production of calcaneal bone plates fully comply with international medical device regulations throughout the process, ensuring the safety of clinical use.

② Precision Manufacturing and Quality Control: The Foundation for Ensuring Fixation Effect

Material Selection: Prioritize the use of medical titanium alloy, balancing strength and biocompatibility to avoid the risk of metal ion release; for patients with osteoporosis, some models use titanium alloy materials with elastic modulus closer to bone tissue to reduce stress shielding;

Process Control: Through five-axis CNC precision machining, ensure that the tolerance of the bone plate's curved surface is controlled within ±0.1mm, and the screw hole position matches the anatomical angle of the calcaneus; the surface is treated with anodization to improve corrosion resistance and osseointegration affinity;

Full-Process Testing: Finished products must pass mechanical strength tests (such as shear resistance and bending resistance) and sterility tests. Random samples from each batch undergo "stability tests simulating the in vivo environment" to eliminate fixation failure caused by manufacturing defects.

③ Flexible Production and Services: Adapting to Diverse Clinical Needs

Multi-Specification Routine Products: Cover bone plate models for different calcaneal sizes and fracture types, such as thickened types for intra-articular fractures and multi-directional screw hole types for comminuted fractures;

Customization Support: For special anatomical shapes (such as calcaneal developmental abnormalities) or complex fracture cases, customized bone plate design and small-batch production can be completed within 72 hours according to the patient's CT data to meet personalized fixation needs;

OEM/ODM Cooperation: Support customer brand customization and process adjustment to adapt to clinical habits and market needs in different regions.

III. Geasure Calcaneal Bone Plates: Core Design and Value Meeting Clinical Needs

(I) Anatomical Adaptation Design: Reducing Surgical Trauma and Improving Fixation Fit

① 3D Bionic Curved Surface: Fitting the Lateral Wall of the Calcaneus

The bone plate adopts a 3D bionic design based on a large amount of calcaneal anatomical data, and its curved surface completely fits the shape of the lateral wall of the calcaneus. It does not require extensive bending during surgery, reduces soft tissue dissection and periosteal damage, and lowers the risk of postoperative infection. For example, the convex design for the calcaneal tuberosity area can accurately wrap the fracture fragments and avoid displacement after fixation.

② Reduction-Assisted Structure: Reducing Surgical Operation Difficulty

Some models integrate reduction guide screw holes and height positioning marks to help doctors quickly restore the length, width of the calcaneus and Böhler angle (a key anatomical angle of the calcaneus), reducing the number of intraoperative fluoroscopies; for bone plates targeting intra-articular fractures, screw holes perpendicular to the calcaneoastragaloid joint surface are set to ensure that screws can accurately fix intra-articular fracture fragments and restore the flatness of the joint surface.

(II) Multi-Dimensional Fixation Mechanism: Addressing Different Fracture Types

① Dual Functions of Locking and Compression

The bone plate has both locking screw holes and compression screw holes: locking screws form an "angular stable" structure to avoid screw loosening and withdrawal; compression holes can apply axial compression to the fracture end to promote fracture healing, adapting to different fixation needs from simple fractures to comminuted fractures.

② Multi-Directional Screw Hole Layout

For comminuted fractures, the bone plate is designed with multi-directional (such as 0°, 15°, 30°) screw holes, which can form "reticular fixation" for scattered comminuted fracture fragments and improve overall stability; the calcaneal tuberosity fixation area adopts thickened screw holes to enhance the grip on calcaneal tuberosity fracture fragments and adapt to weight-bearing transmission needs.

(III) Scenario-Specific Adaptation: Covering All Types of Calcaneal Fractures

① Adaptation to Intra-Articular Fractures

For Sanders type II-IV intra-articular fractures, the bone plate adopts a thickened articular surface support area design to enhance the fixation strength of displaced articular surfaces and reduce the risk of postoperative traumatic arthritis; the supporting small-diameter screws can accurately fix small intra-articular fracture fragments and avoid bone damage.

② Adaptation to Comminuted Fractures

The multi-directional locking screw + reticular hole design can effectively fix multiple comminuted fracture fragments; some models are equipped with supporting bone graft grooves to facilitate filling of autologous bone, allogeneic bone or artificial bone, fill bone defect areas, and improve fixation stability.

③ Adaptation to Special Populations

Elderly Patients with Osteoporosis: Adopt a low-profile design to reduce compression on bone tissue; the screw holes are compatible with bone cement-augmented screws to enhance fixation effect;

Adolescent Patients: Select lightweight titanium alloy materials to reserve space for bone growth and avoid affecting calcaneal development.
