Orthocon MONTAGE Settable. Resorbable Bone Putty is indicated to fill bony voids or gaps in the skeletal system (i.e., extremities and pelvis). These osseous defects may be the result of benign bone cysts and tumors (in adults and pediatric patients ≥ 6 years old), are surgically created or the result of traumatic injury to the bone. MONTAGE is indicated only for filling bony voids or gaps that are not intrinsic to the integrity of the bony structure.

When hardened in situ, MONTAGE may be used to augment provisional hardware (e.g., kwires, plates and screws) and to help support bone fragments during the surgical procedure.

The hardened putty acts only as a temporary support medium and is not intended to provide structural support during the healing process.

MONTAGE can be drilled and tapped, and hardware can be placed through it at any time during the setting process.

Orthocon Montage-QS Settable, Resorbable Bone Putty is indicated to fill bony voids or gaps in the skeletal system (i.e., extremities and pelvis). These osseous defects may be the result of benign bone cysts and tumors (in adults and pediatric patients ≥ 6 years old), are surgically created or the result of traumatic injury to the bone. Montage-QS is indicated only for filling bony voids or gaps that are not intrinsic to the integrity of the bony structure.

When hardened in situ, Montage-QS may be used to augment provisional hardware (e.g., k-wires, plates and screws) and to help support bone fragments during the surgical procedure. The hardened putty acts only as a temporary support medium and is not intended to provide structural support during the healing process.

MONTAGE-QS can be drilled and tapped, and hardware can be placed through it at any time during the setting process.

Orthocon MONTAGE Flowable Settable, Resorbable Bone Paste is indicated to fill bony voids or gaps in the skeletal system (i.e., extremities and pelvis). These osseous defects may be the result of benign bone cysts and tumors (in adults and pediatric patients ≥ 6 years old), are surgically created or the result of traumatic injury to the bone. Montage Flowable is indicated only for filling bony voids or gaps that are not intrinsic to the integrity of the bony structure.

When hardened in situ, Montage Flowable may be used to augment provisional hardware (e.g., kwires, plates and screws) and to help support bone fragments during the surgical procedure. The hardened paste acts only as a temporary support medium and is not intended to provide structural support during the healing process.

Montage Flowable can be drilled and tapped, and hardware can be placed through it at any time during the setting process.

Orthocon Montage-XT Settable. Resorbable Hemostatic Bone Putty is indicated to fill bony voids or gaps in the skeletal system (i.e., extremities and pelvis). These osseous defects may be the result of benign bone cysts and tumors (in adults and pediatric patients ≥ 6 years old), are surgically created or the result of traumatic injury to the bone. Montage-XT is indicated only for filling bony voids or gaps that are not intrinsic to the integrity of the bony structure.

When hardened in situ, Montage-XT may be used to augment provisional hardware (e.g., k-wires, plates and screws) and to help support bone fragments during the surgical procedure. The hardened putty acts only as a temporary support medium and is not intended to provide structural support during the healing process.

Montage-XT can be drilled and tapped, and hardware can be placed through it at any time during the setting process.

The devices are sterile, biocompatible, resorbable material for use in filling bony voids or gaps in skeletal bones of the extremities. Each device comprises two separate components of putty-like consistency containing granular calcium phosphate, calcium stearate, vitamin E acetate, a triglyceride, polyalcohol(s) and a mixture of a lactide-diester and polyester-based polymers. When mixed together, the components of each device form a cohesive material that adheres to the bone surface and remains in place following application. The resulting hardened is primarily calcium phosphate. The components must be mixed immediately prior to use. MONTAGE can be drilled and tapped, and hardware can be placed through it at any time during the setting process.

This document is a 510(k) summary, which is a premarket submission made to FDA to demonstrate that the device to be marketed is at least as safe and effective as a legally marketed predicate device. Unfortunately, it does not contain the detailed acceptance criteria and study results you would find in a clinical study report or a more comprehensive premarket submission (like a PMA).

This document focuses on demonstrating substantial equivalence to existing predicate devices, particularly for an expanded indication for use. It highlights the addition of "benign bone cysts and tumors (in adults and pediatric patients ≥ 6 years old)" to the current Indications for Use statement for four Orthocon MONTAGE products.

Therefore, I cannot provide the specific details about acceptance criteria or a study that proves the device meets those criteria, as requested in your prompt. The information related to sample size, data provenance, expert ground truth establishment, adjudication methods, MRMC studies, standalone performance, and ground truth for training sets is simply not present in this type of FDA clearance letter and 510(k) summary.

The document explicitly states: "Any difference between the subject device and the predicate and reference devices have been addressed through risk assessment, and no new verification testing was required to mitigate the potential risks. All the pre-clinical, and clinical testing conducted to support the previous 510(k) clearances are applicable to the subject device." This indicates that the current submission relies on previously conducted studies for the original clearances of these products, and no new studies were performed specifically for this expanded indication to generate new performance data against specific acceptance criteria.
