Two-Column Distal Radius 2.4 or 2.7mm Volar Locking Plate Set – Standard 22, Narrow 19.5, Wide 25.5mm SS with Instruments

The Two-Column Distal Radius 2.4 or 2.7mm Plates SS & Screws Set With Instruments is a comprehensive surgical implant and instrument system for volar locking plate fixation of distal radius fractures, supplied in surgical-grade stainless steel with individual PS-series part numbers for full traceability. The set encompasses three plate widths — Standard 22mm, Narrow 19.5mm, and Wide 25.5mm — each available in left and right configurations and in 2-, 3-, and 4-hole shaft variants, covering the anatomical range from smaller female wrists through larger male or high-demand active-patient presentations. Plates feature a Safety-Lock Variable Angle two-column volar design with six or seven locking head holes, accommodating both 2.4mm and 2.7mm screw diameters. The accompanying screw assortment includes variable-angle star-drive locking screws and safety-lock star-drive locking screws spanning 8mm through 30mm in length, plus cortical shaft screws and all required implantation instruments, housed in a labelled aluminium box. Used by hand surgeons, orthopedic trauma surgeons, and wrist surgeons in hospital operating rooms, hand surgery units, and orthopedic trauma centers. Sold as 1 complete set.

Two-Column Volar Plate Architecture: Variable-Angle Locking and Width Selection

The two-column volar plate concept for distal radius fixation is based on the biomechanical model of the distal radius as two structural columns — the radial column supporting the scaphoid facet and radial styloid, and the intermediate column supporting the lunate facet and sigmoid notch. A plate that independently stabilizes both columns provides superior subchondral support and resistance to secondary displacement compared to single-column designs, particularly in comminuted intra-articular fractures where both columns are disrupted. The Safety-Lock Variable Angle design in this set addresses the practical limitation of fixed-angle locking: because distal radius fracture fragment geometry varies considerably between patients, fixed screw trajectories may miss the subchondral bone in smaller or atypically shaped wrists. Variable-angle locking — the star-drive screw interface that allows up to approximately 15° of angular freedom per hole — permits the surgeon to direct each distal locking screw independently toward subchondral bone in the scaphoid and lunate facets under fluoroscopic guidance, optimising support beneath the articular surface regardless of plate position. The three-width system — Narrow 19.5mm (PS-135 series), Standard 22mm (PS-130 series), and Wide 25.5mm (PS-136 series) — allows size matching to the patient's native volar plate width measured on pre-operative CT or fluoroscopy, reducing the risk of plate overhang onto the pronator quadratus or flexor tendons at either end of the plate footprint. Each width is available in 2-, 3-, and 4-hole shaft configurations (per left and right side), giving the surgeon control over proximal plate length relative to the shaft fracture line or distal osteotomy level.

Surgical Application: Distal Radius ORIF Indications and Plate Selection Rationale

Open reduction and internal fixation with a volar locking plate is the standard surgical approach for displaced distal radius fractures where closed reduction and cast immobilisation cannot maintain acceptable alignment, and for intra-articular fractures with step-off exceeding 2mm at the articular surface. Primary indications for this set include AO/OTA type 23-B and 23-C fractures — radial styloid fractures with intra-articular extension, die-punch fragments, and complete articular fractures with dorsal comminution — as well as extra-articular 23-A fractures in patients where early wrist mobilization is required for occupational or functional reasons. The choice between the 2.4mm and 2.7mm screw diameter within this set reflects patient-specific bone density and fracture complexity: 2.4mm screws are preferred for smaller, more osteoporotic wrists where the distal fragment is thin and screw purchase in cancellous bone is adequate, while 2.7mm screws provide greater cortical purchase and shear resistance in denser bone or in patients with anticipated high post-operative loads. The narrow 19.5mm plate is selected for patients with smaller wrist anatomy — typically female patients or patients with a volar plate width below 20mm on pre-operative imaging — to prevent radial-side overhang over the first extensor compartment or flexor carpi radialis sheath. The wide 25.5mm plate, configured with seven head holes rather than six, is indicated for wider wrists requiring broader subchondral support across the lunate facet and sigmoid notch in complex articular patterns.

Screw Assortment: Variable-Angle and Safety-Lock Star-Drive Locking Screws, 8–30mm

The screw component of this set is organized into two functionally distinct locking screw categories, both using the star-drive (Torx-type) head geometry that provides superior torque transmission and lower risk of driver tip cam-out compared to hexagonal or Phillips drives — a practical advantage when placing small-diameter locking screws through a deep surgical approach into the volar distal radius. The variable-angle safety-lock (PS-100V series) screws, provided in 2.4mm diameter from 8mm through 30mm length in 2mm increments, are for placement in the distal head holes where angular flexibility is required to achieve independent subchondral positioning of each screw. The safety-lock (PS-100S series) screws, also in 2.4mm diameter from 8mm through 18mm, are fixed-angle locking screws for applications where the surgeon has confirmed that the standard head-hole trajectory will correctly engage the target fragment, providing slightly higher pullout resistance than variable-angle designs at a fixed trajectory. The screw length range — from 8mm for very thin distal fragments to 30mm for shaft-length engagement in longer plates — eliminates the need for intraoperative screw sourcing outside the set. The corresponding 2.7mm screw assortment and cortical shaft screws for the plate stem holes complete the implant component, all provided in individual PS-series parts with quantity multiples that reflect the typical intraoperative consumption pattern for each screw size.

Surgical Grade Stainless Steel Construction and Implant Integrity

All plates and screws in this set are manufactured from surgical-grade stainless steel, the implant alloy standard that provides the corrosion resistance, yield strength, and fatigue resistance required for load-bearing internal fixation of the distal radius during the six to twelve weeks of fracture consolidation. Surgical-grade stainless steel implants are compatible with post-operative MRI at standard field strengths, an important consideration for wrist surgery patients who may require MRI assessment of the triangular fibrocartilage complex, extrinsic ligaments, or carpal bones in the post-operative period. The plates are machined to dimensional tolerances that ensure consistent screw engagement at each locking hole and smooth plate profile at the volar cortex contact surface, minimising periosteal irritation and the risk of flexor tendon abrasion at the plate edges. The aluminium storage box maintains plate and screw organization between cases, supports sterile field inventory count, and protects the implant surfaces from mechanical damage during storage and transport. Plates and screws are individually catalogued by PS-series part number, enabling selective component replenishment without full set replacement when individual size categories are depleted through clinical use.

Frequently Asked Questions

What fractures is this distal radius plate set designed to treat?
This set is designed for open reduction and internal fixation of displaced distal radius fractures where cast management alone cannot maintain acceptable alignment or where articular reduction is required. Primary indications include AO/OTA type 23-C complete articular fractures with dorsal comminution, intra-articular fractures with articular step-off exceeding 2mm, radial styloid fractures with significant displacement, die-punch fractures depressing the lunate facet, and extra-articular fractures in patients for whom early mobilization is functionally necessary. The two-column volar plate design — stabilising both the radial column at the scaphoid facet and the intermediate column at the lunate facet — provides the subchondral support needed to prevent secondary articular collapse after reduction, which is the principal failure mechanism of less rigid fixation constructs in osteoporotic or comminuted fracture patterns. The variable-angle star-drive locking screws allow the surgeon to independently direct each distal screw toward the subchondral bone, optimising support across the articular surface regardless of the fracture fragment geometry. The three-plate-width system — Narrow 19.5mm, Standard 22mm, and Wide 25.5mm — accommodates the anatomical variation in volar plate width across the patient population encountered in a general hand surgery or orthopedic trauma service.

When should the 2.4mm screws be chosen over the 2.7mm screws, and vice versa?
The 2.4mm screw diameter is appropriate for the majority of distal radius fractures, particularly in patients with smaller wrist anatomy, female patients, osteoporotic bone, or thin distal fragments where the available cancellous bone volume in each head hole is limited. The smaller thread profile of 2.4mm screws reduces the risk of screw-to-screw interference when multiple locking screws are placed in the densely perforated distal plate segment, and allows more flexibility in screw trajectory angulation within the variable-angle holes. The 2.7mm screws provide greater cross-sectional area and thread depth per screw, offering higher individual screw pullout resistance and shear strength — advantages in patients with good bone density, higher body mass, or post-operative loading demands associated with manual labor or high-activity use. In practice, many hand surgeons default to 2.4mm throughout the distal segment for the trajectory flexibility benefit and reserve 2.7mm screws for the shaft holes or for cases where a specific fragment requires higher fixation strength. The set provides both diameters, allowing the surgeon to apply each where the clinical situation dictates rather than committing to a single diameter pre-operatively.

How does the variable-angle star-drive locking mechanism differ from fixed-angle locking?
Fixed-angle locking plates lock each screw at a single predetermined angle defined by the thread geometry of the screw hole in the plate. This offers predictable screw positioning but constrains the surgeon to that trajectory regardless of fracture anatomy, bone loss, or plate positioning variations. In the distal radius, where the distal fragment may be thin, comminuted, or rotated, fixed-angle screws may fail to engage subchondral bone or may penetrate the articular surface if the plate is not positioned at the exact planned location on the volar cortex. The variable-angle Safety-Lock design in this set allows each distal locking screw to be angled up to approximately 15° off axis within its head hole, giving the surgeon intraoperative freedom to direct screws individually toward the subchondral bone of the scaphoid facet, lunate facet, or radial styloid under fluoroscopic control. Once the screw is seated, the Safety-Lock mechanism locks it at the chosen angle without the secondary locking step required by some competing variable-angle systems. The star-drive head geometry provides reliable torque transfer with lower cam-out risk than hexagonal heads, which is practically significant when driving small-diameter locking screws through the restricted exposure of a volar Henry approach.

What sterilization methods are compatible with the instruments in this set?
The reusable surgical instruments included with this set are compatible with steam autoclave sterilization at standard pre-vacuum cycle parameters of 134°C / 273°F, which is the recommended routine reprocessing method. Ethylene oxide and hydrogen peroxide plasma sterilization are also compatible with the stainless steel instrument components. The implants — plates and screws — are single-use devices and should not be resterilized after implantation. Unused implants that have been exposed to the sterile field but not implanted may be reprocessed according to the facility's single-use device reprocessing policy where permitted by local regulations. The aluminium box should be confirmed as autoclave-compatible with the facility's sterilization equipment before direct processing of instrument components. Pre-cleaning of all instrument interfaces via manual brushing and ultrasonic processing prior to terminal sterilization is required to ensure removal of bone debris and tissue from driver recesses and guide sleeve interiors.

What regulatory certifications does this implant set carry?
The Distal Radius Plates SS & Screws Set is manufactured under an ISO 13485-certified quality management system covering all stages of production including raw material procurement, precision machining, dimensional inspection, surface finishing, sterile packaging, and PS-series part-level traceability. CE Mark certification confirms conformity with European Medical Device Regulation requirements for Class II metallic bone fixation implants and accessories distributed in EU and associated regulatory territories.
