Intended Use
The Hoffmann LRF (Limb Reconstruction Frame) System is intended for fixation of fractures, joint contractures, fusions, limb lengthening, deformity correction, bone and soft tissue reconstruction in pediatric patients and adults. The Stryker Hoffmann LRF (Limb Reconstruction Frame) System is indicated in pediatric patients and adults for the treatment and fixation of: - Open and Closed Fractures - Post-traumatic joint contracture which has resulted in loss of range of motion - Fractures and disease which generally may result in joint contractures or loss of range of motion and fractures requiring distraction - Pseudoarthrosis or non-union of long bones - Limb lengthening by epiphyseal or metaphyseal distraction - Correction of bony or soft tissue deformity - Correction of segmental bony or soft tissue defects - Joint arthrodesis - Management of comminuted intra-articular fractures of the distal radius The Stryker Hoffmann LRF System is indicated in adults for: - Osteotomy - Revision procedure where other treatments or devices have been unsuccessful - Bone reconstruction procedures - Fusions and replantations of the foot - Charcot foot reconstruction - Lisfranc dislocations
Device Description
This Traditional 510(k) submission is being supplied to the U.S. FDA to provide authorization to market the modified telescopic strut and wire bolt components of the Hoffmann LRF (Limb Reconstruction Frame) System, previously cleared in K113327. The Hoffmann LRF System is an external fixation device that consists of Carbon and Aluminum Full/Open rings and ring segments, Aluminum foot rings, threaded rods and threaded rod connecting nuts, telescopic struts, static struts and connection bolts, posts and connecting nuts, wires and wire bolts, wire bolt offset adapters, pin bolts and pin adapters. This external fixation system may also be used with the components of other Stryker Trauma AG external fixation systems such as the Monticelli Spinelli External Fixation System, the Hoffmann II MRI External Fixation System, and the Stryker Trauma Pelvic Set and in conjunction with commercially available Apex Pins, Hoffmann II External Fixation 90° Post, Carbon Connecting Rod and Miami Post.
More Information

Not Found

No
The document describes a mechanical external fixation system and its components, with no mention of software, algorithms, or AI/ML capabilities.

Yes
The device is described as an external fixation system used for the treatment and fixation of various medical conditions, including fractures, joint contractures, limb lengthening, and deformity correction, all of which are considered therapeutic interventions.

No

Explanation: The device description states it is an external fixation device used for treatment and fixation of fractures, deformities, and for limb lengthening. Its intended use is therapeutic (fixation, correction, lengthening) rather than diagnostic (identifying or characterizing a condition).

No

The device description explicitly lists numerous hardware components such as rings, rods, struts, bolts, and wires, indicating it is a physical external fixation system, not software only.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use/Indications for Use: The intended use and indications clearly describe a device used for the fixation and manipulation of bones and soft tissues in the body (fractures, fusions, limb lengthening, deformity correction, etc.). This is a surgical or orthopedic device, not a diagnostic one.
  • Device Description: The description details the physical components of an external fixation system (rings, rods, struts, bolts, wires, etc.). These are mechanical components used to stabilize and manipulate the skeletal structure.
  • Lack of Diagnostic Function: There is no mention of the device being used to analyze samples (blood, urine, tissue, etc.) or to provide information about a patient's health status based on such analysis.

IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device operates in vivo (within the body) to provide structural support and manipulation.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-Clinical Testing: Non-clinical laboratory testing was performed for the Hoffmann LRF (Limb Reconstruction Frame) System on the modified telescopic strut and wire bolt components. Testing was performed with compliance to ASTM F1541-02 -- "Standard Specification and Test Methods for External Skeletal Fixation Device." Testing demonstrated that the Hoffmann LRF (Limb Reconstruction Frame) System modified components are substantially equivalent to the predicate device components previously cleared in K113327. Testing included the following:
Telescopic Strut

  • Dynamic and Static Component Testing
  • Dynamic and Static Construct Testing

Wire Bolt

  • Dynamic Construct Testing
  • Pull Out Testing

Clinical Testing: Clinical testing was not required for this submission.

Conclusion: The Hoffmann LRF (Limb Reconstruction Frame) System is substantially equivalent to the predicate devices identified in this premarket notification.

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
