Shoulder (bankart repair), Hand (ulnar or lateral collateral ligament reconstruction), Wrist (scapholunate ligament reconstruction), Foot (hallux valgus reconstruction), and Ankle (midfoot reconstructions)
Made from surgical grade stainless steel (316L), the LM Anchor is designed with a crown and a center pin through which suture is passed to provide a means for soft tissue to bone attachment.
This document is a 510(k) summary for a medical device (LM Anchor) and does not contain the information requested regarding acceptance criteria and a study proving a device meets those criteria, as typically found in submissions for AI/ML-driven imaging or diagnostic devices.
The provided text describes a bone anchor and its pre-clinical testing, which focuses on mechanical performance (pullout strength). It lacks any mention of:
- Acceptance criteria (quantitative metrics like sensitivity, specificity, AUC)
- Studies involving test sets, ground truth, experts, or comparative effectiveness with AI.
- Training sets or how their ground truth was established.
- Any AI or machine learning component.
The "Performance Data" section simply states: "Pre-clinical testing in cadaver specimen showed that the mean pullout strength of the LM Anchor was substantially equivalent to the mean pullout strength of the Mitek Mini Anchor." This is a comparison of mechanical properties, not diagnostic or interpretive performance.

| Device Description: | Made from surgical grade stainless steel (316L), theLM Anchor is designed with a crown and a center pinthrough which suture is passed to provide a means forsoft tissue to bone attachment. |
| Intended Use: | Shoulder (bankart repair), Hand (ulnar or lateralcollateral ligament reconstruction), Wrist(scapholunate ligament reconstruction), Foot (halluxvalgus reconstruction), and Ankle (midfootreconstructions) |
| Technical Comparison: | The LM Anchor is similar to the Mitek Mini Anchor inits cylindrical shape, however, the bony purchase isaccomplished by the LM Anchor through cantileveredbeams versus nitinol arcs with the Mitek Mini Anchor. |
| Performance Data: | Pre-clinical testing in cadaver specimen showed thatthe mean pullout strength of the LM Anchor wassubstantially equivalent to the mean pullout strength ofthe Mitek Mini Anchor. |
§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
