Minimally Invasive Metaphyseal Fixation: The Unified 4.0mm Cannulated Cancellous Screw (CCS) Instrument System
Periarticular fractures of the ankle, midfoot, elbow, and pediatric physes frequently involve thin soft-tissue envelopes where extensive open dissection increases the risk of wound dehiscence and hardware irritation. By placing a fine Ø 1.2mm or Ø 1.4mm guide wire across the reduced fracture fragment under C-arm fluoroscopy first, surgeons can verify anatomical reduction and trajectory in two planes before committing to bone preparation.
Recognized across hospital value analysis committees and international public health tenders as a turnkey 4.0mm Cannulated Cancellous Screw (CCS) Instrument System, our 4mm Cannulated Screw Instrument Set routes every subsequent step—drilling, countersinking, depth measurement, tapping, and screw driving—coaxially over the placed guide wire. This preserves periosteal blood supply, minimizes articular cartilage disruption, and reduces total fluoroscopy time.
Coaxial Concentric Engineering: Small Fragment Cannulated Lag Screw Instrument Set Capabilities
Achieving rigid interfragmentary lag compression in cancellous and corticocancellous bone without stripping the near cortex or shearing fine guide wires requires strict mechanical tolerances. Configured as a high-precision Small Fragment Cannulated Lag Screw Instrument Set, this platform incorporates five core engineering features:
- Three-Part Coaxial Protection & Trocar Assembly: A serrated-tip outer soft-tissue protection sleeve locks against the bone cortex while housing an inner Ø 2.7mm drill sleeve and a Ø 1.2mm/1.4mm wire sleeve—protecting superficial nerves (such as the saphenous or superficial peroneal nerve) and tendons during percutaneous entry.
- Adjustable Parallel Wire Guide (Twin-Screw Anti-Rotation): When fixing rotational fragments such as the medial malleolus or humeral capitellum, the sliding parallel guide sleeve locks over the first K-wire and guides a second K-wire at a parallel offset, guaranteeing uniform compression across both screws.
- Calibrated Ø 2.7mm Core Drill & Ø 4.0mm Gliding-Hole Drill: Includes a cannulated Ø 2.7mm twist drill for standard pilot-hole preparation, plus a cannulated Ø 4.0mm over-drill for creating a near-cortex gliding channel when using fully threaded 4.0mm screws in lag mode.
- Cannulated Cortical Countersink & Washer Compatibility: Features a cannulated profile countersink to recess the 4.0mm screw head flush in dense cortical bone, alongside a self-retaining screw holding sleeve compatible with Ø 7.0mm flat or spiked buttress washers in osteoporotic metaphyseal bone.
- Direct-Read Guide-Wire Depth Gauge & 2.5mm Hex Drivers: The laser-etched direct depth gauge slides over the guide wire to provide an immediate millimeter readout (automatically subtracting 2mm–4mm for lag compression pull-in), paired with both cannulated and solid 2.5mm Hexagonal screwdrivers.
High-Volume Clinical Indications: Turnkey Medial Malleolus, Ankle, and Foot Fracture Fixation Set
By combining percutaneous reduction forceps, parallel wire guides, and calibrated cannulated tooling in one compact layout, trauma centers and specialty podiatric/orthopedic clinics can execute a wide range of lower- and upper-extremity procedures. Operating as an all-in-one Medial Malleolus, Ankle, and Foot Fracture Fixation Set, the system supports:
Lower Extremity, Pediatric & Upper Extremity Applications
- Ankle & Malleolar Fractures (AO/OTA 44-A, 44-B & 44-C): Percutaneous twin-screw fixation of transverse or oblique medial malleolus fractures, posterior malleolus (Volkmann triangle) shear fragments, and anterolateral Chaput / Tillaux tibial tubercle avulsions.
- Midfoot, Hindfoot & Metatarsal Trauma: Talar neck/body fractures, navicular and cuboid fractures, Lisfranc tarsometatarsal arthrodesis/fixation, calcaneal tuberosity avulsions, and intramedullary fixation of Jones fifth-metatarsal base fractures managed with our Medial Malleolus, Ankle, and Foot Fracture Fixation Set.
- Forefoot Osteotomies & Arthrodesis: First metatarsophalangeal (MTP) joint arthrodesis, proximal/distal first metatarsal hallux valgus osteotomies, and midfoot fusions.
- Pediatric Physeal Fractures & Epiphysiodesis: Salter-Harris Type II, III, and IV epiphyseal fractures (distal tibia, distal femur, and proximal tibia) and percutaneous transphyseal hemiepiphysiodesis for angular limb deformity correction.
- Upper Extremity Metaphyseal & Condylar Fractures: Lateral humeral condyle fractures, medial epicondyle avulsions, olecranon tip fractures, radial styloid fractures, and glenoid rim fractures.
Sterile Processing (SPD) Efficiency & Modular Graphic Case Architecture
Hospital Sterile Processing Departments (SPD) and operating room managers evaluate small-fragment cannulated trays on lumen cleanability, guide-wire organization, and rapid visual inventory counts. Our 4mm Cannulated Screw Instrument Set is housed in a perforated, hard-anodized aluminum sterilization container paired with medical-grade silicone holders.
- High-Flow Steam Perforation Geometry: Engineered with an open-surface perforation ratio exceeding 45% to guarantee rapid steam penetration and moisture evacuation during standard pre-vacuum steam sterilization cycles (132°C / 270°F for 4 minutes).
- Dedicated Lumen Flushing Access & Stylet Wires: Includes stainless steel lumen-cleaning stylets and open-access drill brackets that allow thorough ultrasonic enzymatic flushing and visual inspection of every cannulated shaft between surgeries.
- Ergonomic Modular Split-Tray Design: Cannulated Screw Drivers, Cannulated Drill Bits, and Double Drill Guide are distributed in Herbert Screw Instrument Set across balanced, stackable modular tiers so the loaded sterilization case remains strictly below the 25 lb (11.3 kg) AAMI ST77 limit.
Direct OEM & Global Supply: Certified 4mm Cannulated Screw Instrument Set Manufacturer
Sourcing small-fragment cannulated instrumentation directly from a dedicated 4mm Cannulated Screw Instrument Set Manufacturer eliminates third-party distributor markups and guarantees the strict coaxial concentricity required for Ø 1.2mm and Ø 1.4mm guide-wire workflows. Deep-hole gun-drilling of Ø 2.7mm twist drills and 2.5mm hex driver shafts requires precision CNC lathes and internal bore honing so that drills never bind, overheat, or shear K-wires inside the ankle or foot.
- Hardened Cannulated Cutting Metallurgy: Cannulated drills, countersinks, and taps are machined from stainless steel, vacuum heat-treated to 50–54 HRC for enduring cutting sharpness and high torsional shear resistance.
- Custom OEM Guide-Wire & Drive Calibration: As a full-service 4mm Cannulated Screw Instrument Set Manufacturer, we configure sets for either Ø 1.2mm or Ø 1.4mm guide-wire systems and calibrate driver tips for 2.5mm Hexagonal to match your exact implant blueprint.
- Global Regulatory & Tender Compliance: Manufactured in an ISO 13485:2016 certified facility.
Frequently Asked Questions
Q1: What guide-wire diameter does this 4.0mm Cannulated Cancellous Screw (CCS) Instrument System use?
Our 4.0mm Cannulated Cancellous Screw (CCS) Instrument System is available in standard Ø 1.25mm guide-wire calibration (matching AO/Synthes 4.0mm CCS specifications) as well as Ø 1.4mm heavy-duty guide-wire calibration to match regional implant preferences. Both configurations use 150mm calibrated threaded and trocar wires.
Q2: Can this Small Fragment Cannulated Lag Screw Instrument Set place both partially and fully threaded 4.0mm screws?
Yes. Engineered as a complete Small Fragment Cannulated Lag Screw Instrument Set, the tray includes both the Ø 2.7mm core drill for standard partially threaded lag screws and the Ø 4.0mm cannulated gliding-hole drill for over-drilling the near cortex when using fully threaded 4.0mm screws in lag or positional mode.
Q3: Why is an adjustable parallel wire guide included in this Medial Malleolus, Ankle, and Foot Fracture Fixation Set?
When stabilizing rotational periarticular fragments—such as transverse medial malleolus fractures, talar neck fractures, or lateral humeral condyle fractures—a single screw cannot resist rotational torque. The adjustable parallel wire guide in our Medial Malleolus, Ankle, and Foot Fracture Fixation Set locks onto the primary guide wire and places a second wire at a precise parallel offset, ensuring both 4.0mm screws compress along the exact same vector without colliding.
Q4: What are the sterilization parameters for the 4mm Cannulated Screw Instrument Set container?
The anodized aluminum sterilization container is validated for standard hospital pre-vacuum steam autoclave sterilization at (132°C / 270°F) for 4 minutes with a minimum 20–30 minute drying cycle, as well as 134°C (273°F) for 3 minutes under European/WHO sterilization protocols.
