Intended Use

The ArthroCare® Parallax® Contour® Vertebral Augmentation Device when used with the access needle kits are indicated for use during kyphoplasty or vertebral augmentation procedures to create a void in the vertebral body and fill the void with Parallax Acrylic Resin (bone cement). The painful pathological vertebral body compression fractures may result from osteoporosis, benign or malignant lesions such as metastatic cancers and myeloma.

Device Story

Device disrupts cancellous bone to create void in vertebral body; facilitates delivery of Parallax Acrylic Resin (PMMA bone cement) during kyphoplasty/vertebral augmentation. Used in clinical settings by physicians. Input: manual manipulation of device within vertebral body. Output: physical void creation; subsequent cement delivery. Benefits: enables increased cement volume delivery compared to standard vertebroplasty; reduces VAS pain scores in patients with compression fractures. Clinical evidence shows significant pain reduction and safe, effective void creation.

Clinical Evidence

Prospective clinical study evaluated efficacy of Contour device with PMMA cement. Results: void volume 0.33–2.02 cc; PMMA instillation 2.9–8.5 cc. Mean VAS pain score significantly reduced (p<0.01) to 2.19 ± 0.41. Four cases of asymptomatic PMMA extravasation observed; no other complications. Pre-clinical cadaveric study demonstrated increased cement delivery volume compared to standard vertebroplasty.

Technological Characteristics

Manual surgical instrument for vertebral augmentation. Components include access needle kits and bone cement delivery mechanism. Materials and mechanical performance validated via torque, insertion, withdrawal, and flexure testing. No electronic or software components; purely mechanical device.

Indications for Use

Indicated for patients with painful pathological vertebral body compression fractures resulting from osteoporosis, or benign/malignant lesions (e.g., metastatic cancers, myeloma) undergoing kyphoplasty or vertebral augmentation.

Regulatory Classification

Identification

Polymethylmethacrylate (PMMA) bone cement is a device intended to be implanted that is made from methylmethacrylate, polymethylmethacrylate, esters of methacrylic acid, or copolymers containing polymethylmethacrylate and polystyrene. The device is intended for use in arthroplastic procedures of the hip, knee, and other joints for the fixation of polymer or metallic prosthetic implants to living bone.

Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance Document: Polymethylmethacrylate (PMMA) Bone Cement.”

Predicate Devices

• Parallax Contour Osteotome Access Needle Kits (K072133)
• AVAflex Vertebral Augmentation Needle (K072133)

#### Product Description

The ArthroCare Parallax Contour Vertebral Augmentation Device is used to disrupt cancellous bone and create a void in the vertebral body and fill the void with Parallax Acrylic Resin (bone cement) during kyphoplasty or vertebral augmentation procedures.

#### Intended Uses

The Parallax Contour Vertebral Augmentation Device when used with the access needle kits are indicated for use during kyphoplasty or vertebral augmentation procedures to create a void in the vertebral body and fill the void with Parallax Acrylic Resin (bone cement). The painful pathological vertebral body compression fractures may result from osteoporosis, benign or malignant lesions such as metastatic cancers and myeloma.

#### Substantial Equivalence

In establishing substantial equivalence to the predicate device, ArthroCare compared the indications for use, performance specifications, and technology of the subject device to the predicate device. Functional performance testing of the device included torque, insertion and withdrawal, flexure, device attachment/deployment/removal and mechanical displacement of bone have been completed to demonstrate the mechanical characteristics of the device.

A pre-clinical cadaveric study was conducted to evaluate the size void created by the Contour and predicate devices, as well as the volume of Parallax PMMA bone cement delivered during vertebral augmentation. This study demonstrated equivalence in performance of the Contour and predicate devices when used in cadaveric vertebral bodies. In addition, studies were also conducted to characterize Parallax bone cement volume distributed in human cadaver fractured vertebral discs. The test group used the Contour device to create a void prior to vertebral augmentation with bone cement; in the control group the Contour device was not used prior to vertebral augmentation. Comparative data between test group and the control group is reported in terms of relative fill of cement volume per vertebral body volume. Results demonstrates the Contour may be use to successfully create a void in the vertebral body, and that use of Contour device prior to cement augmentation allows significantly more cement delivery into the vertebral body compared to the standard vertebroplasty procedure. Testing was also conducted to compare the performance of the Contour and predicate devices in terms of volume of void created in simulated human foam bone blocks. Based on the results of the study, the void volumes were all similar in size, and no statistically significant differences were noted between the two devices. The pre-clinical studies demonstrate the Contour device performs equivalent to the predicate device.

A clinical study was conducted to evaluate clinical efficacy of the Contour device used in conjunction with PMMA bone cement to fill voids that have been created during perculaneous vertebral augmentation. The outcome showed the volume of the void percularious vertebral body using the Contour ranged from 0.33 to 2.02 cc for individual patients; the volume of PMMA instillation ranged from 2.9 to 8.5 cc; four cases

demonstrated imaging evidence of PMMA extravasation into the paravertebral veins, all four cases were asymptomatic; and after the mean follow-up period, the mean VAS pain score was significantly reduced (dependent t-test, p<0.01), where the post-procedure mean score was 2.19 +/- 0.41 points. In all cases, no patient complications were observed. The results of the study demonstrated percutaneous vertebral augmentation using the Contour device was safe and effective for treating symptomatic vertebral compression fractures.

The performance testing, device comparison, pre-clinical, and clinical studies demonstrate that the subject device is substantially equivalent to the predicate device, and is safe and effective.

#### Summary of Safety and Effectiveness

The Parallax Contour Vertebral Augmentation Device, as described in this premarket notification 510(k), is substantially equivalent to the predicate device. The differences in performance specifications and labeling are not substantial changes or modifications, and do not significantly affect the safety or efficacy of the proposed device.
