Indications for Use
Indicated for use in patients with a grossly rotator cuff deficient shoulder joint with severe arthropathy or a previously failed joint replacement with a grossly rotator cuff deficient shoulder joint. The patient's joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is necessury to use the device. The glenoid baseplate is intended for comentless application with the addition of screws for fixation. The humeral stem is intended for cemented use only.
Device Story
RSP Modular Glenoid Baseplate is a modular orthopedic implant component for reverse shoulder arthroplasty. It serves as a multi-piece construct to replace the single-piece design of the predicate. The device is implanted by a surgeon in a clinical/OR setting. It is fabricated from Ti-6Al-4V (ASTM F136) with a porous commercially pure titanium (ASTM F67) bead coating and hydroxyapatite (ASTM F1185) coating. Fixation is achieved cementlessly via an incorporated 6.5mm cancellous screw and four peripheral screws (3.5mm/5mm locking or non-locking). The device restores shoulder joint function in patients with rotator cuff deficiency by providing a stable base for the prosthetic assembly. The female taper geometry is identical to the Turon Shoulder system.
Clinical Evidence
No clinical data provided. Substantial equivalence is supported by non-clinical mechanical fatigue and dynamic testing.
Technological Characteristics
Modular glenoid baseplate; material: wrought/forged Ti-6Al-4V (ASTM F136); porous coating: commercially pure titanium beads (ASTM F67 grade 2); surface treatment: hydroxyapatite (ASTM F1185); fixation: cementless with 6.5mm cancellous screw and peripheral 3.5mm/5mm screws; female taper geometry matches Turon Shoulder (K080402).
Indications for Use
Indicated for patients with grossly rotator cuff deficient shoulder joint with severe arthropathy or failed joint replacement. Requires anatomically/structurally suited joint and functional deltoid muscle.
Regulatory Classification
Identification
A shoulder joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder 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 humeral resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a glenoid resurfacing component made of ultra-high molecular weight polyethylene, and is limited to those prostheses intended for use with bone cement (§ 888.3027).
