DHSDCS Plate Implants Set – 95°–135° Plates and 50–115 mm Lag Screws

DHSDCS Plate Implants Set, SKU PS-OP-7197, is a German stainless steel orthopedic implant inventory for sliding hip screw and dynamic condylar screw fixation. The 40-implant configuration contains nine 135° dynamic hip compression plates: four units of 4-hole model 166.024, two 5-hole 166.025, two 6-hole 166.026, and one 8-hole 166.028. Six 95° DCS plates are supplied as 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. The 25 standard lag-screw assemblies have a 12.5 mm diameter and include compression screws: one 50 mm model 168.050; two each from 55–105 mm, models 168.055–168.105; one 110 mm 168.110; and one 115 mm 168.115. The components are organized in container 903.042. Orthopedic trauma surgeons use compatible selections during open reduction and internal fixation of intertrochanteric and selected proximal femoral fractures with DHS constructs, and distal femoral or supracondylar fractures with DCS constructs. The inventory supports hospital operating rooms, trauma centers, teaching institutions, distributors, and implant procurement teams managing measured plate and lag-screw selection for primary fixation, corrective femoral osteotomy, and compatible revision procedures.

Sliding Barrel and Compression Screw Mechanics

The DHS construct couples a large-diameter lag screw in the femoral head or neck to the barrel of a 135° lateral plate. The barrel maintains the prescribed screw-to-plate relationship while permitting controlled axial sliding at the screw-barrel interface after the construct is assembled. The lag screw’s deep thread profile engages cancellous bone, and its smooth shaft travels within the plate barrel as compression occurs across the reduced fracture. The included compression screw threads into the internal end of the lag screw and is used to draw the screw relative to the barrel when deliberate intraoperative compression is required by the selected technique. DCS geometry applies the same screw-and-barrel principle at a fixed 95° relationship for condylar fixation, with the plate extending proximally along the lateral distal femur. Plate holes accept compatible shaft fixation that anchors the side plate to the diaphysis. Longer plate bodies increase the available span for screw distribution and bridge a greater femoral segment. The 12.5 mm lag-screw diameter remains constant across the inventory, while length changes the depth of osseous purchase. These implants require compatible guide-wire, measuring, reaming, tapping, insertion, plate-seating, and shaft-screw instrumentation supplied separately from this implant-only set.

Proximal and Distal Femoral Implant Workflow

For intertrochanteric fixation, fracture reduction is established before a compatible guide system directs a wire through the femoral neck toward the planned position in the femoral head. After anteroposterior and lateral fluoroscopic assessment, the surgeon measures over the accepted wire and selects the corresponding 50–115 mm lag screw. Cannulated preparation and tapping are completed with matching DHS instrumentation before the implant is advanced to the planned depth. A 4-, 5-, 6-, or 8-hole 135° plate is passed over the lag-screw shaft and seated against the lateral proximal femur. Compatible diaphyseal screws secure the plate, and the compression screw is applied when the operative plan calls for controlled approximation through the sliding barrel. During distal femoral or supracondylar reconstruction, a 95° guide establishes the condylar trajectory before measurement, reaming, screw insertion, and placement of a 6- to 16-hole DCS plate. Plate length is selected according to fracture extension, bone quality, working length, and the number of diaphyseal fixation points required by the construct. The inventory also supports compatible corrective osteotomy and revision planning where DHS or DCS geometry is selected. Every implant remains dependent on the corresponding manufacturer-compatible instruments and plate screws for preparation, insertion, and definitive fixation.

Plate Span and Lag-Screw Length Options

The 135° DHS group progresses from four-hole 166.024 to five-hole 166.025, six-hole 166.026, and eight-hole 166.028. These plates preserve the same angular relationship while increasing lateral diaphyseal span. Four units of the shortest pattern support routine proximal femoral inventory demand; two each of the five- and six-hole versions provide intermediate coverage, and one eight-hole plate addresses a longer construct. The 95° DCS family begins with six-hole 167.006 and continues through eight-hole 167.008, ten-hole 167.010, twelve-hole 167.012, fourteen-hole 167.014, and sixteen-hole 167.016. Each progressively longer model allows the side plate to extend farther proximally from the condylar segment. Lag screws retain a 12.5 mm diameter and increase from 50 to 115 mm in 5 mm increments. One unit is included at 50, 110, and 115 mm, while two units are supplied at every length from 55 through 105 mm. Selection follows direct measurement over the final guide-wire position; plate choice follows the planned femoral segment, fracture morphology, and required shaft fixation. The compression screw accompanies each lag screw as the internal control component for compatible axial compression through the barrel.

Implant Material, Handling, and Compliance Records

German stainless steel provides the mechanical strength, dimensional stability, and corrosion resistance required across plate barrels, countersunk holes, lag-screw shafts, deep threads, and internal compression-screw connections. Machined implant surfaces support accurate engagement with compatible insertion tools and the prescribed sliding interface. The set is supplied non-sterile and must be processed before use under the healthcare facility’s validated implant-handling and sterilization protocol. Each model should remain identifiable by code, size, quantity, lot, packaging status, and processing history from receipt through operating-room issue. Components placed on the sterile field are controlled according to facility policy and product labeling, and implanted or contaminated items are not returned to available stock. The aluminum container supports organized storage but does not replace validated packaging for terminal sterilization. CE marking and manufacture under an ISO 13485 quality management system support conformity documentation, controlled production, traceability, and corrective-action records. For United States purchasing, FDA-compliant procurement requires evaluation of applicable establishment, listing, labeling, intended-use, and import documentation for the delivered configuration. Receiving staff should reconcile all 40 implants and container 903.042 against the table, isolate damaged or incomplete components, and maintain separate replenishment records for each plate pattern and lag-screw length.

Specification

How does this implant set differ from the DHS/DCS Plate Implant Instruments Set?
The DHS/DCS Plate Implants Set contains only the plate and lag-screw inventory required for compatible femoral fixation constructs. The DHS/DCS Plate Implant Instruments Set combines the same plate families and 50–115 mm lag-screw range with guide wires, reamers, taps, sleeves, drivers, impactors, and measuring tools. This implant-only configuration is intended for facilities that already maintain compatible DHS/DCS instrumentation. It contains nine DHS plates, six DCS plates, and 25 lag-screw assemblies. No reusable preparation or insertion tools are included with SKU PS-OP-7197. Procurement teams should select the configuration according to their existing instrument inventory and planned implant-replenishment model.

How should surgeons select the plate and lag-screw dimensions?
The 135° DHS plates address compatible proximal femoral constructs and provide four-, five-, six-, and eight-hole shaft options. The 95° DCS plates address distal femoral or supracondylar fixation and span six through sixteen holes. A longer plate increases the available diaphyseal coverage and number of compatible fixation positions. Lag-screw length is selected from direct measurement over the final guide-wire trajectory after fluoroscopic acceptance. The 50–115 mm range accommodates different femoral-neck, head, and condylar depths in 5 mm increments. The DHS/DCS Plate Implants Set is selected against fracture morphology, bone dimensions, planned working length, and the corresponding operative technique.

What do CE, ISO 13485, and FDA-compliant procurement mean for this set?
CE marking supports the applicable European conformity documentation for the supplied implant configuration. ISO 13485 identifies the quality management system used for controlled production, traceability, corrective action, and medical-device records. These credentials support hospital and distributor qualification but do not replace destination-market review. For United States orders, FDA-compliant procurement requires 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-7197. Procurement personnel should retain documentation connecting every model, length, quantity, and lot to the received stock.

How does the compression screw control the DHS or DCS construct?
The compression screw engages the internal thread at the trailing end of the 12.5 mm lag screw. After the lag screw and barrel plate are positioned, tightening draws the screw relative to the plate barrel. This mechanism applies controlled axial approximation across the prepared fracture plane when the compatible technique requires it. The barrel preserves the prescribed 135° DHS or 95° DCS relationship while allowing the lag-screw shaft to slide along its axis. Compression is applied with the designated driver and only after implant position and plate seating have been assessed. Each lag-screw assembly in the DHS/DCS Plate Implants Set includes its corresponding compression screw.

How should hospitals receive, sterilize, and replenish this implant inventory?
Receiving staff should reconcile 40 implants and container 903.042 against the code-and-quantity table. Plate angle, hole count, lag-screw length, lot, and packaging condition should be recorded for each component. The non-sterile inventory must be processed using the healthcare facility’s validated implant workflow before presentation to the sterile field. Used, implanted, contaminated, damaged, or unidentified components must remain outside available stock. Replenishment records should distinguish DHS plate models, DCS plate lengths, and each 5 mm lag-screw increment. OEM assortment changes, documentation, replacement stock, and reordering support are available for the DHS/DCS Plate Implants Set.
