DHS/DCS Plate Implants Set – 40-Implant Hip and Condylar Fixation Inventory

DHS/DCS Plate Implants Set, SKU PS-OP-7186, is a 40-implant German stainless steel inventory for proximal and distal femoral plate-screw constructs. The 135° DHS group contains four 4-hole plates, model 166.024; two 5-hole 166.025; two 6-hole 166.026; and one 8-hole 166.028. The 95° DCS group contains one each of 6-hole 167.006, 8-hole 167.008, 10-hole 167.010, 12-hole 167.012, 14-hole 167.014, and 16-hole 167.016. Standard lag screws have a 12.5 mm diameter and include compression screws: one 50 mm model 168.050; two units at each 5 mm increment from 55–105 mm, models 168.055–168.105; one 110 mm 168.110; and one 115 mm 168.115. Container 903.042 organizes the complete assortment. Orthopedic trauma surgeons select these components for DHS fixation of intertrochanteric and selected proximal femoral fractures, DCS fixation of distal femoral and supracondylar fractures, and compatible corrective osteotomy or revision constructs. The inventory is intended for hospitals, trauma centers, orthopedic clinics, distributors, and operating-room supply teams that already maintain the corresponding guide-wire, measuring, reaming, tapping, insertion, impactor, and plate-screw instrumentation.

Fixed-Angle Plate and Sliding Lag-Screw Geometry

Each DHS plate combines a lateral shaft with a barrel positioned at 135°, preserving the planned relationship between the proximal femoral lag screw and the diaphyseal plate. The 12.5 mm screw carries a coarse cancellous thread for femoral-head purchase and a smooth shaft that enters the barrel. This interface allows axial translation along the screw’s established trajectory while preventing uncontrolled angular change between the plate and implant. The compression screw engages the internal thread at the trailing end of the lag screw and draws the screw relative to the barrel when deliberate intraoperative approximation is required by the selected technique. The DCS plate uses the same barrel-and-screw principle at 95°, placing the lag screw across the condylar segment while the plate extends proximally along the lateral distal femur. Countersunk shaft holes accept compatible plate fasteners for diaphyseal anchorage. Increasing the hole count lengthens the plate body and distributes available fixation positions across a larger femoral segment. The implant-only set does not contain control instruments; wire guidance, direct measurement, stepped reaming, tapping, screw driving, plate seating, and final shaft fixation require compatible DHS/DCS instrumentation. The fixed barrel angle and measured screw length must therefore correspond with the operative plan and selected anatomical site.

Fracture Fixation and Implant Placement Sequence

In an intertrochanteric procedure, the proximal femur is reduced before compatible instrumentation directs a threaded wire through the femoral neck toward the planned position within the head. Anteroposterior and lateral fluoroscopic views establish trajectory and depth before the measuring device determines the lag-screw length. The surgeon prepares the cannulated path, taps when indicated by the operative technique, and advances the selected 50–115 mm screw. A 135° DHS plate with four, five, six, or eight holes is passed over the implant shaft and seated on the lateral cortex. Compatible shaft screws then secure the plate, and the internal compression screw is used when controlled fracture approximation through the sliding barrel is intended. For distal femoral or supracondylar fixation, a 95° guide establishes the condylar axis before measurement, reaming, lag-screw placement, and attachment of a six- through sixteen-hole DCS plate. Longer models provide additional proximal reach for extended fracture patterns or corrective osteotomy constructs. During revision, extraction requires the corresponding removal instruments after all plate fasteners and the barrel interface are released. The inventory supplies implant choices only; it does not replace the system-specific reusable tools or compatible diaphyseal screws required to complete fixation.

Forty-Implant Size Distribution

The set provides nine proximal femoral plates at a fixed 135° angle. Model 166.024 has four holes and is supplied in four units; 166.025 has five holes and is supplied in two; 166.026 has six holes and is supplied in two; and 166.028 has eight holes and is supplied as one. The distal femoral group contains six 95° DCS plates, with one each of models 167.006, 167.008, 167.010, 167.012, 167.014, and 167.016. Their six-, eight-, ten-, twelve-, fourteen-, and sixteen-hole shafts provide progressively greater diaphyseal span. Twenty-five lag-screw assemblies complete the implant count. Each screw measures 12.5 mm in diameter and includes its compression component. The 50 mm, 110 mm, and 115 mm lengths are supplied singly; every option from 55 through 105 mm is supplied in duplicate at 5 mm intervals. Direct intraoperative measurement determines screw selection after the final guide-wire position is accepted. Plate selection depends on the 135° DHS or 95° DCS construct, fracture extent, bone dimensions, planned working length, and the number of compatible shaft fixation points required.

Implant Processing, Traceability, and Procurement

German stainless steel provides corrosion resistance, dimensional stability, and mechanical strength across the plate shaft, fixed barrel, screw body, cancellous thread, and internal compression connection. Machined surfaces maintain engagement with compatible drivers and preserve the intended sliding interface between the lag-screw shaft and plate barrel. The implants are supplied non-sterile and require processing under the healthcare facility’s validated implant protocol before presentation to the sterile field. Receiving and sterile-services teams should preserve identification by product code, plate angle, hole count, screw length, quantity, lot, packaging condition, and processing history. Container 903.042 supports organized storage but is not a substitute for validated terminal-sterilization packaging. Used, implanted, contaminated, damaged, or unidentified components must remain segregated from available inventory. CE marking and manufacture under ISO 13485 support conformity documentation, controlled production, traceability, and corrective-action records. For United States purchasing, FDA-compliant procurement involves review of the applicable establishment, listing, labeling, intended-use, and import documentation associated with the supplied configuration. Before case issue, personnel should reconcile all 40 implants against the table and confirm that compatible instruments and plate fasteners are separately available for the planned procedure.

Specification

How does this combined DHS/DCS set differ from a DHS Implant Set?
A DHS Implant Set is limited to proximal femoral sliding hip screw constructs and normally contains 135° plates with corresponding lag screws. The DHS/DCS Plate Implants Set adds 95° condylar plates for distal femoral and supracondylar fixation. Its DHS range includes four-, five-, six-, and eight-hole plates. Its DCS range extends from six through sixteen holes for longer distal femoral constructs. Both pathways use compatible 12.5 mm lag screws, but the plate angle and anatomical target differ. Hospitals selecting this combined inventory can stock both proximal and distal femoral plate patterns within one coded set.

Which plate pattern and lag-screw length should be selected?
The 135° DHS models are selected for a compatible proximal femoral construct after reduction and guide-wire trajectory planning. The 95° DCS models are selected for distal femoral or supracondylar fixation using the prescribed condylar axis. Increasing the plate hole count extends the available diaphyseal span and number of fixation positions. Lag-screw selection follows direct measurement over the accepted wire rather than visual estimation. The inventory covers 50–115 mm in 5 mm increments for different femoral-head, neck, and condylar depths. The DHS/DCS Plate Implants Set is matched to fracture morphology, measured bone depth, plate working length, and compatible instrumentation.

What do CE, ISO 13485, and FDA-compliant procurement mean for this inventory?
CE marking supports the applicable European conformity documentation for the supplied implant configuration. ISO 13485 identifies the quality management system used for production controls, traceability, corrective action, and medical-device records. These credentials support supplier qualification but do not replace hospital or destination-market review. For United States purchasing, FDA-compliant procurement involves evaluation of applicable establishment, listing, labeling, intended-use, and import documentation. The DHS/DCS Plate Implants Set can be accompanied by commercial and quality records linked to SKU PS-OP-7186. Procurement teams should retain documentation connecting every implant model, quantity, length, and lot to the received inventory.

How does the compression screw interact with the sliding barrel?
The compression screw threads into the internal trailing end of the 12.5 mm lag screw. Once the lag screw and side plate are positioned, the component draws the screw relative to the fixed barrel when tightened with the designated driver. This action provides controlled axial approximation when required by the compatible DHS or DCS technique. The plate barrel maintains the 135° hip or 95° condylar relationship while the smooth screw shaft translates along its axis. The mechanism is used only after the surgeon has assessed implant depth, fracture reduction, and plate seating. Every lag-screw assembly in the DHS/DCS Plate Implants Set includes its corresponding compression component.

How should operating-room supply teams control this implant set?
Receiving personnel should reconcile 40 implants and container 903.042 against the current table. Records should identify plate angle, hole count, lag-screw length, quantity, lot, and packaging condition. The non-sterile components require processing through the facility’s validated implant workflow before sterile-field presentation. Used, implanted, contaminated, damaged, or unidentified items must remain separated from available stock. Replenishment should be managed at individual model level because the plate and screw quantities are not uniform across the range. OEM assortment changes, supporting documentation, replacement stock, and reordering assistance are available for the DHS/DCS Plate Implants Set.
