Titanium Wires Cable Cercage Wire Orthopedic Instrument Set

Titanium Wires Cable Cercage Wire Orthopedic Instrument Set

The Titanium Wire Cable Fixation Orthopedic Instrument Set represents a unique “flexible internal fixation” system. Instead of relying on rigid steel plates, it achieves circumferential fixation, binding, and tension band stabilization through high-strength titanium alloy cables and precision locking mechanisms. Its core value lies in providing flexible, minimally invasive, and biologically compatible fixation solutions for complex fractures and revision surgeries.

Technical Specifications

Advantages:

1. Superior biomechanical effects: When applying the ‘tension band principle’ (positioning cables on the tension side of the bone), physiological tension is converted into compressive force at the fracture site, significantly promoting healing. Examples include applications in patella fractures and olecranon fractures.

2. Preservation of Bone Haemodynamics: Compared to bulky plates, slender cables exert minimal pressure and cause less periosteal detachment on bone surfaces, thereby better safeguarding the bone's blood supply and aligning with biological fixation principles.

3. Resolving complex challenges: In stabilising periprosthetic fractures following total hip or knee arthroplasty, cable systems are virtually the standard solution. They securely bind and fixate fracture fragments without compromising the prosthesis itself.

4. Acting as a robust ‘support’: Often employed in conjunction with plates or intramedullary nails, it binds comminuted bone fragments unsecured by plates or anchors long-segment graft bone to the host bone, functioning as a ‘stirrup’ to enhance overall structural stability.

Clinical application scenarios

Application Scenarios:

1. Periprosthetic Fractures

Circumferential fixation for fractures around femoral or tibial prostheses following hip/knee arthroplasty.

2. Augmentation of Comminuted Fractures

Spiral comminuted fractures of the femur, tibia, or humerus, where cable fixation is employed to consolidate bone fragments.

3. Fractures Following the ‘Tension Band’ Principle

Tension band fixation for patella fractures, olecranon fractures, and avulsion fractures of the greater trochanter.

4. Osteotomy and Arthrodesis

Binding fixation of graft bone blocks during spinal correction, ankle arthrodesis, and similar procedures.

5. Bone reconstruction in revision surgery

Following removal of old implants, used to repair bone defects or reinforce fragile cortical bone.

The titanium wire cable system is not intended to replace steel plates and screws, but rather serves as a crucial functional supplement and extension to them. Its advantage lies in addressing fixation challenges around prostheses, as well as circular, comminuted, and irregular fractures – issues where steel plates prove difficult to resolve.

Key usage principles: Must be employed with dedicated tensioning devices to apply appropriate and uniform tension (typically with recommended torque values). Insufficient tension may cause fixation failure, while excessive tension risks cable rupture or bone cutting.
