Lowman Bone Clamp – 7.25 in, 1×2 Prong Jaws for Orthopedic Bone Reduction

Lowman Bone Clamp, SKU PS-000046 and part number gS 46.2540, is a reusable orthopedic bone approximation clamp manufactured from German surgical stainless steel for controlled stabilization, manipulation, and reduction of bone during fracture fixation and reconstructive procedures. The instrument measures 7 1/4 in overall and incorporates a 1 × 2 prong jaw configuration that provides opposed points of contact around an accessible osseous segment. The characteristic Lowman clamp design uses a manually adjustable locking mechanism to bring the jaws together progressively, allowing the surgeon to establish secure temporary fixation while preserving control over compression. This configuration is used during open reduction and internal fixation, long-bone fracture surgery, osteotomy, corrective reconstruction, plate application, and other procedures where fragments must remain aligned during drilling or implant placement. The 7.25-inch length provides useful working reach without the bulk of larger bone clamps. Orthopedic trauma surgeons and reconstructive teams use the Lowman pattern where stable bone approximation and controlled fragment positioning are required before definitive fixation.

1×2 Prong Jaw and Screw-Controlled Approximation Mechanism

The Lowman Bone Clamp uses a 1 × 2 prong arrangement to establish controlled contact across opposing bone surfaces. One side engages through a single working point while the opposite side uses two prongs, creating a three-point relationship that can stabilize the targeted bone segment during manipulation or reduction. The Lowman pattern incorporates a threaded vice-style adjustment mechanism rather than a conventional finger-ring ratchet. Turning the control progressively changes the distance between the jaws, allowing closure to be introduced in small increments while the surgeon observes fragment alignment and cortical contact. This mechanical arrangement can maintain the selected position without continuous squeezing of the handles, leaving the operator free to assess reduction or proceed with fixation. Because screw advancement increases compression progressively, the clamp should be tightened only until adequate purchase and stability are achieved. Excessive closure can create unwanted cortical pressure, particularly in thin, osteoporotic, comminuted, or otherwise fragile bone. The prongs should be placed on visible, appropriate osseous surfaces with surrounding soft tissue protected before compression is applied.

Fracture Reduction, Plate Fixation and Reconstruction Workflow

During open reduction and internal fixation, the Lowman Bone Clamp can be positioned after surgical exposure has created a safe path to the fracture fragments. The surgeon places the 1 × 2 jaws around appropriate cortical surfaces and progressively closes the adjustment mechanism while restoring length, alignment, and rotational orientation. Once the desired reduction is established, the clamp maintains temporary approximation while direct inspection or fluoroscopic imaging confirms fragment position. The stable hold can support plate placement, provisional fixation, drilling, depth measurement, and screw insertion when the clamp does not obstruct the intended implant trajectory. During corrective osteotomy, the same mechanism can hold divided bone surfaces in the selected relationship while angular, translational, or rotational correction is evaluated. In reconstructive procedures, it can stabilize bone during graft placement or other fixation steps requiring temporary compression. The clamp should not be used to compensate for an inaccurate reduction by applying excessive force. If the prongs are poorly positioned or the fragment relationship remains unsatisfactory, the mechanism should be released and the clamp repositioned before definitive fixation proceeds.

gS 46.2540 7.25-Inch Length and 1×2 Jaw Selection

Part number gS 46.2540 identifies the exact Lowman Bone Clamp supplied through Peak Surgicals under SKU PS-000046. This model measures 7 1/4 in overall and uses a 1 × 2 prong configuration. The established Lowman family also includes a compact 5-inch 1 × 2 clamp and an 8-inch 1 × 2 configuration, as well as separate 1 × 1 jaw patterns. The 7.25-inch model provides an intermediate working length suitable for a broad range of open orthopedic fracture and reconstruction procedures where a 5-inch instrument may provide insufficient reach and an 8-inch clamp may introduce unnecessary size. A 1 × 2 configuration provides a different contact geometry from 1 × 1 patterns and should be selected according to the available cortical surface, fracture morphology, required control, and implant pathway. Hospitals should maintain gS 46.2540 with the 7.25-inch and 1 × 2 specifications in purchasing and tray records rather than treating all Lowman clamps as interchangeable. Instrument selection should account for bone dimensions, operative depth, soft-tissue access, fracture stability, and the degree of temporary approximation required.

German Stainless Steel, Reprocessing and Procurement Standards

German surgical stainless steel provides the strength, corrosion resistance, dimensional stability, and surface durability required for a reusable orthopedic clamp exposed to repeated compression and sterilization cycles. Reprocessing should begin promptly after surgery so blood, marrow, bone debris, and other contamination do not dry around the prongs, jaw surfaces, threaded adjustment mechanism, structural joints, or handle. The clamp should be opened sufficiently during cleaning so all contacting surfaces and threads are accessible. Thorough rinsing and complete drying should follow before functional inspection. Sterile-processing personnel should examine all three prongs for bending, tip damage, corrosion, or loss of alignment and confirm that the screw-control mechanism advances and releases smoothly without binding. Threads and moving interfaces should remain free of retained residue and should receive instrument-compatible lubrication when required by the facility's validated maintenance procedure. Terminal steam sterilization should follow the healthcare facility's validated reusable stainless steel instrument protocol. Peak Surgicals supports CE and ISO 13485 procurement documentation, with applicable FDA-related records maintained within hospital and distributor supplier-qualification files.

How does the Lowman Bone Clamp differ from Verbrugge Bone Holding Forceps?
The Lowman Bone Clamp uses a characteristic 1 × 2 prong configuration and a screw-controlled approximation mechanism for progressive bone compression. Verbrugge Forceps commonly use opposed bone-holding jaws with a handle-operated ratchet that maintains the selected closure position. The Lowman mechanism allows small incremental changes in jaw spacing by adjusting the threaded control. This can be useful when controlled approximation of fracture fragments is required before plating or screw fixation. Verbrugge patterns may provide greater lever-style manipulation and rotational handling through longer forceps bodies. Selection should therefore reflect fracture geometry, required compression, preferred locking mechanism, operative depth, and the amount of fragment manipulation required.

Why select the 7.25-inch 1×2 Lowman Bone Clamp?
The 7 1/4 in overall length provides an intermediate working reach within the Lowman 1 × 2 family. A shorter 5-inch configuration can be useful for superficial or smaller-bone applications, while an 8-inch pattern provides additional reach for deeper exposure. The 1 × 2 prongs create three points of osseous contact and support controlled fragment stabilization during reduction. Lowman Bone Clamp PS-000046 is therefore suited to procedures where moderate working length and secure mechanical approximation are required. Instrument length alone does not determine safe clamping force because bone quality and prong placement remain critical. Selection should follow fracture location, operative depth, cortical dimensions, implant pathway, and the amount of temporary compression required.

What do CE, ISO 13485 and FDA references mean for procurement?
Peak Surgicals displays CE, FDA, and ISO-related information for the Lowman Bone Clamp and supports ISO 13485 procurement documentation. ISO 13485 concerns the quality-management system used for controlled medical-device manufacturing and associated processes. CE documentation supports conformity assessment within applicable medical-device markets. FDA AccessGUDID identifies exact model gS 46.2540 as a commercially distributed Lowman Bone Clamp and classifies its device type as a bone approximation clamp. A GUDID record should not be described as individual FDA approval of PS-000046. Hospitals and distributors can retain the SKU, part number, supplier certificates, regulatory records, and purchasing documentation within their vendor-qualification files.

How does the screw-lock mechanism control bone approximation?
The Lowman pattern uses a threaded adjustment mechanism that changes the distance between the opposed prong jaws progressively. Turning the control brings the 1 × 2 jaw surfaces toward the bone in small increments rather than closing them abruptly through a spring action. This permits the surgeon to observe fragment alignment and cortical contact while increasing approximation. Once the selected position is reached, the mechanism maintains the jaw relationship without continuous hand compression. Further tightening increases compression and should only be performed when clinically required. If the prongs do not obtain appropriate purchase, the clamp should be released and repositioned rather than tightened excessively against an unsuitable cortical surface.

How should hospitals order and reprocess the Lowman Bone Clamp?
Hospitals should order this Lowman Bone Clamp using SKU PS-000046 and part number gS 46.2540 together with the 7 1/4 in length and 1 × 2 prong specification. Peak Surgicals currently lists the product at $77.00 and displays a 30-day money-back guarantee. Standard online purchasing begins with one piece, while institutional and distributor requirements can be coordinated for larger or custom orders. Following surgery, blood, tissue, marrow, and bone debris should be removed promptly from the prongs, jaws, threaded mechanism, and all surface transitions. Cleaning should be followed by thorough rinsing, complete drying, and inspection of prong alignment, screw movement, corrosion, and structural integrity. Final steam sterilization should follow the healthcare facility's validated reusable stainless steel instrument process before PS-000046 returns to the orthopedic bone-holding and fracture-reduction tray.
