Indications for Use
The DALL-MILES System is indicated for reattachment of the trochanter in any hip procedure using the trochanteric osteotomy (total or partial) approach. The DALL-MILES Mini Cleat is indicated for vertical reattachment of the trochanter in any situation where the surgeon feels that the trochanter is at risk for detachment. The Mini Cleat is intended for use with the DALL-MILES System for trochanteric reattachment only. The DALL-MILES Cables and Cable Sleeves are indicated for trochanteric reattachment and trauma surgery of the hip; to stabilize bone graft material; and for supplementary cerclage fixation with plates and screws for fracture fixation. The DALL-MILES Trochanteric Grips and Grip Plates are indicated for use in the fixation of the greater trochanter due to trochanteric fracture or osteotomy with intramedullary fixation as the primary device. The DALL-MILES Trochanteric Grip Plate is additionally indicated for use in the fixation of the greater trochanter due to extended trochanteric osteotomies.
Device Story
Dall-Miles Cable System consists of metallic cables, beaded cables, sleeves, trochanteric grips, grip plates, and mini cleats; used for bone fixation in orthopedic hip surgeries. Devices are implanted by surgeons in an OR setting to stabilize bone fragments or reattach the trochanter. System provides mechanical fixation; no electronic or software components. This submission updates labeling to MR Conditional status based on non-clinical testing. Benefits include secure bone fixation during healing.
Clinical Evidence
No clinical data. Substantial equivalence supported by non-clinical bench testing for MR compatibility.
Technological Characteristics
Components manufactured from stainless steel or cobalt chromium alloy (Vitallium). Passive metallic bone fixation implants. MR Conditional status established via testing per ASTM F2052-15 (displacement force), ASTM F2213-17 (torque), ASTM F2119-07 (image artifact), and ASTM F2182-19 (RF heating).
Indications for Use
Indicated for patients undergoing hip procedures involving trochanteric osteotomy, trochanteric fracture fixation, trauma surgery of the hip, stabilization of bone graft material, or supplementary cerclage fixation with plates and screws.
Regulatory Classification
Identification
A bone fixation cerclage is a device intended to be implanted that is made of alloys, such as cobalt-chromium-molybdenum, and that consists of a metallic ribbon or flat sheet or a wire. The device is wrapped around the shaft of a long bone, anchored to the bone with wire or screws, and used in the fixation of fractures.

Dear Margaret Klippel:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
{1}------------------------------------------------
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.

## Non-Clinical Testing:
The following non-clinical laboratory testing was performed to determine substantial equivalence:
Non-clinical testing as outlined in the FDA guidance document "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment - Guidance for Industry and FDA Staff", dated December 11, 2014 was conducted to characterize the compatibility of Stryker Orthopaedics Dall-Miles Cable System in the MR environment. FDA guidance "Assessment of Radiofrequency-Induced Heating in the Magnetic Resonance (MR) Environment for Multi-Configuration Passive Medical Devices – Guidance for Industry and FDA Staff", dated March 22, 2016 was also consulted for the heating evaluations performed. Testing was performed according to the standards listed below:
- Magnetically Inducted Displacement Force - performed per ASTM F2052-15, Standard Test Method for Measurement of Magnetically Induced Displacement Force on Medical Devices in the MR Environment
- Magnetically Induced Torque performed per ASTM F2213-17. Standard Test Method 0 for Measurement of Magnetically Induced Torque on Medical Devices in the MR Environment
- . Image Artifact - performed per ASTM F2119-07 (Reapproved 2013), Standard Test Method for Evaluation of MR Image Artifacts from passive Implants
- Heating by RF Fields per ASTM F2182-19. Standard Test Method for Measurement of . Radio Frequency Induced Heating near Passive Implants during MR Imaging
The labeling has been modified to include the MR conditional symbol, and to provide the parameters under which a patient who has the device can be safely scanned.
Clinical Testing: Clinical testing was not required as a basis for substantial equivalence.
Conclusion: The Dall-Miles Cable System components are substantially equivalent to the predicate devices identified in this premarket notification.
