Arthrosurface HemiCAP DF®
Arthrosurface® HemiCAP DF® offers three different restoration systems to treat toe pain: the HemiCAP DF® (Dorsal Flange), the Toe Classic HemiCAP® with no flange and the ToeMotion™ Modular Toe System. The Toe Classic is primarily used in early disease where a simple resurfacing will suffice or for the lesser metatarsals. The HemiCAP DF® is used in the 1st metatarsal and incorporates an anatomic, extended dorsal curve to improve dorsal roll-off while preventing osteophyte regrowth. For patients with late stage disease who may not want a fusion because of their work or activity demands, Arthrosurface has developed the ToeMotion™ Modular Toe System. The ToeMotion™ restores mobility and maintains native biomechanics using the dual curved HemiCAP DF® and modular tray-style phalangeal implant with a threaded baseplate. Fourth generation fixation components provide stable constructs on both sides of the joint. All Arthrosurface systems are available in a variety of different convexities designed to fit the implant to the patient’s native anatomy.
- Screw based implants provide rock solid fixation
- HemiCAP DF® dual implant curvatures improve dorsal role-off and prevent osteophyte regrowth
- ToeMotion™ screw-in baseplate and modular poly inserts provides optimal intraoperative flexibility
- Super smooth articulating cobalt chrome surface to minimize wear on the opposing side
- Conical shaped screw to optimize bone-screw interface
- Inlay arthroplasty and minimal bone removal allows for future fusion if necessary – “No Bridges Burned”
- Anatomic inlay of Toe Classic HemiCAP® maintains the length of the lesser metatarsals
- Standardised thread pitch for precise depth and decompression
- Proven clinical history with over 20,000 MTP implants
- The HemiCAP® procedure is intuitive and easy to learn
- The minimally invasive outpatient procedure typically takes less than an hour
- Soft-tissue envelope and native joint biomechanics are maintained
- Skeletal anatomy and bone stock are preserved allowing future fusion or total toe
- Phalangeal surface reamer allows for a controlled cheilectomy
- The two components are connected together via morse taper, with zero reported loosening
The WristMotionTM Hemiarthroplasty System
The first choice when you need a second chance
Restores mobility and maintains native biomechanics using a dual curvature HemiCAPITATE® implant that locks into a taper post for strong fixation. The implant is designed to articulate with the natural radius bone and references the curve of the lunate fossa. The system also consists of a set of precision instruments for mapping and site preparation.
- Preserves Motion by Referencing the Native Anatomy of the Lunate Fossa
- Proven Rock-Solid Fixation
- 6 Implant Sizes & Curvatures with Ultra Smooth Surfaces for Improved Volar & Dorsal Flexion
The Arthrosurface WristMotion® Wrist Hemiarthroplasty System consists of a contoured capitate
Articular implant designed to articulate with the native radius bone, a taper post and set of instruments used for implant site preparation and delivery. The capitate articular components are manufactured using implant grade cobalt-chrome alloy and are o ered in six implant options. The taper post is manufactured using implant grade titanium alloy and is o ered in one xed size designed to work with all capitate articular components.
Restoring the Freedom of Motion…
As the outcome scores in this study show, restoring the congruity of the humeral head without altering the soft tissue tension, joint volume, joint height, version or inclination angle allows improved mobility and function.
The Shoulder HemiCAP® Systems restore the articular surface geometry of the humeral head and preserve all of the surrounding structures using an innovative 3-dimensional mapping system and a contoured articular resurfacing implant. The HemiCAP® Shoulder and HemiCAP® OVO systems are approved for use in the US and most European markets for the treatment of articular cartilage defects in the shoulder as well as the gleniod.
HemiCAP® Shoulder & OVO Features
- Proven peer reviewed published data
- 43 anatomically matched humeral implant convexities & 4 inlay glenoid options
- The ovoid shape of the HemiCAP OVO® matches humeral head geometry
- Bone and tissue sparing preserves future primary arthroplasty – “No Bridges Burned”
- Focal & total resurfacing to treat a variety of humeral surface pathology
Inlay Glenoid Features
- An off the shelf, sterile disposable surgical kit
- Partial or Full inlay glenoid virtually eliminates overstuffing
- Glenoid bone preservation permits future onlay options
- Inlay design is stable and anatomic to avoid loosening
- Off-axis preparation of the glenoid socket avoids head removal
The first choice when you need a second chance
To treat ankle pain in our International Markets, we offer the Talus HemiCAP® which has 10 convexities and a unique geometry. There are often patients who only have damage to the ridge and dome of the talus (usually medially). The common solutions for this type of defect are a fusion or total ankle replacement after conservative treatments have failed. For localized talar lesions, these options might be considered too aggressive, especially in a young patient. Arthrosurface® designed the Talus HemiCAP® to restore the dome, ridge and medial wall with all three curves/surfaces incorporated into one implant.
- One implant for 3 surfaces: dome, ridge and medial wall
- Screw based fixation provides a stable implant
- Inlay components restore congruency & maintain existing biomechanics
- Implant protects subchondral bone and shares load with surrounding tissue
- Minimal bone & tissue removal maintains future options – “No Bridges Burned”
The Talus HemiCAP® implant system is comprised of two parts, an articular cap and a fixation component. The surgical procedure begins with an arthroscopy. If the articular defect is deemed appropriate for the HemiCAP® procedure, then a malleolar osteotomy is performed to access the joint. The axis perpendicular to the lesipartial knee replacementon is established with the drill guide and a guide wire is introduced into the middle of the defect. The fixation component is implanted to establish the mechanism for anchoring the articular component. The uniquely designed instruments are used to map the contours of the patient’s native surface curvatures using the fixation component as a central axis. The defect is then prepared for the resurfacing implant. Once the proper fit is confirmed using the trial the HemiCAP® implant is brought into position and seated. The osteotomy site is then set in place with screws and the joint is closed.
