Yes
The device is described as an implant used for the reconstruction of the hip joint due to disease, deformity, or trauma, directly addressing a medical condition.
No
This device is described as an implantable medical device used for the reconstruction of the hip joint. Its purpose is to provide structural support and reinforcement, not to diagnose a condition.
No
The device description clearly describes a physical, metallic implant (a hemispherical metallic cage) intended for surgical implantation in the hip joint. It is a hardware device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Description: The Recovery Protrusio Cage is a physical implant designed to be surgically placed within the hip joint to reconstruct it. It is a mechanical device, not a testing device.
- Intended Use: The intended use is for surgical reconstruction of the hip joint, not for analyzing biological samples.
The provided information clearly describes a surgical implant, which falls under a different category of medical devices than IVDs.

Device Description
The Recovery Protrusio Cage is a hemispherical metallic cage. This malleable commercially pure (CP) titanium cage can be shaped by the surgeon intraoperatively to fit the proper shape of the patient's anatomy. The surface of the device has a grit blasted (roughened) finish for adherence of bone cement.
The purpose of the cage is to provide reinforcement for the acetabular socket and facilitate bone grafting in cases of a severely deficient acetabulum. The pelvic bone grafts are protected from stress overload and potential collapse with the cage. This device can potential resist acetabular migration by serving as a connection between host bone to host bone.
The dome of the cage contains five or six screw holes for component fixation. Two large "windows" in the dome allow for morselized bone impaction and a continuous cement mantle lateral and medial of the device. An anterior cut-out in the dome allows retroverted positioning of the cage without causing impingement of the neck and possible dislocation.
A large illum flange contains six screw holes for component fixation. This flange is designed for a severely deficient acetabulum to allow engagement of the cage to host bone. An inferior obturator foramen hook is positioned beneath the "teardrop" of the ischium to provide further stability of the cage. The illum flange and the obturator foramen hook can be shaped by the surgeon to properly fit the patient's anatomy.
The use of 6.5mm low profile screws placed through any (at least two) or all holes in the dome and large illum flange provide immediate stable fixation of the shell to the pelvis. Adjunctive fixation is achieved with bone cement that adheres an all polyethylene acetabular cup into the shell. The all polyethylene acetabular cup is anteverted to the correct anatomic position within the Recovery cage.

§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.

Device Description: The Recovery Protrusio Cage is a hemispherical metallic cage. This malleable commercially pure (CP) titanium cage can be shaped by the surgeon intraoperatively to fit the proper shape of the patient's anatomy. The surface of the device has a grit blasted (roughened) finish for adherence of bone cement.
The purpose of the cage is to provide reinforcement for the acetabular socket and facilitate bone grafting in cases of a severely deficient acetabulum.14 The pelvic bone grafts are protected from stress overload and potential collapse with the cage. This device can potential resist acetabular migration by serving as a connection between host bone to host bone.1
The dome of the cage contains five or six screw holes for component fixation. Two large "windows" in the dome allow for morselized bone impaction and a continuous cement mantle lateral and medial of the device. An anterior cut-out in the dome allows retroverted positioning of the cage without causing impingement of the neck and possible dislocation.
A large illum flange contains six screw holes for component fixation. This flange is designed for a severely deficient acetabulum to allow engagement of the cage to host bone. An inferior obturator foramen hook is positioned beneath the "teardrop" of the ischium to provide further stability of the cage.
