The Radial Head Plating System may be combined with any of the Acumed anatomic radial head replacement systems and may be found at the bottom of the tray. The operations were performed by two surgeons Yan Xiong acuemd Ziming Wang in our department within ten days of injury. The inclusion criteria ehad all patients with traumatic elbow fracture and instability, where the radial head was comminuted and irreparable at the time of surgery and there was associated valgus laxity of the elbow.

Results All patients treated by the Acumed anatomic radial head system achieved our follow up at a mean follow-up of Stress shielding was detectable by an average of 11 months range, mo. Anatomic Plate 2 lengths and 2 head curvatures provide the surgeons with the options to select the optimal solution for their patients anatomy.

This is different from other stem that causes high contact pressure on the opposing articular cartilage or bone cement [ 9 ]. Click Here to Request More Information.

Disclosure of conflict of interest None. The treatment of comminuted radial head fractures is still challenging.

All operations were performed using the Acumed anatomic radial head prosthesis system within ten days of injury.

The radial head replacement with the AARHS can provide effectively stability and good clinic results at the middle term following up. Late results of excision of the radial head for an isolated closed fracture. One small heterotopic calcification was found in two acu,ed, but it did not cause obvious influence.

The Anatomic Radial Head System tray, which also accommodates the Acutrak 2 Mini and Micro Headless Compression Screw systems and all necessary instrumentation, fit inside the same tray to allow for ease of preoperative assessment. Insertion Depth Laser Mark: For those with instability noted at surgery requiring ligament repair, elbow flexion and extension began at the fourteenth day.

However, it is typically minor, nonprogressive, and of questionable clinical consequence. Comminuted fractures of the radial head treated by the Judet floating radial head prosthesis. We hypothesized that stress shielding around radial head prostheses is common but nonprogressive. Low-profile Design Screws sit flush with the plate for minimized hardware prominence. If between sizes, select the smaller diameter.

Anatomic Radial Head Solutions

Conclusion Stress shielding around radial head prostheses is common, regardless of stem design. Lister’s tubercle may also be used as a landmark for laser mark orientation. Email Updates Yes, please send me updates by email. Standard length stems range from 6—10 mm in diameter in 1 mm increments and 0—8 mm heights in 2-mm incrementsand are fully grit-blasted to promote bony ongrowth.

Our radiological review showed no evidence of peri-prosthetic lucency during the following up. J Bone Joint Surg Br. Contouring of the medial side of the head has been further defined to track against the lateral side of the ulna. The system offers a straightforward solution when the radial head is salvageable.

Influence of radial head prosthesis design on radiocapitellar joint contact mechanics. In this study, we present the results of a small series of 12 patients with ligament repair and fracture fixation to facilitate early mobilization of the elbow. Open reduction and internal fixation of radial head fractures. The Anatomic Radial Head System has evolved from the use of broaches to that of reamers for canal preparation.

The First and Only Anatomic Radial Head Originally released inthe prosthesis has been used in thousands of radial head procedures over multiple system generations and product line improvements.

Radial Head Plating System

A floating prosthesis for radial-head fractures. Journal Abstract Objective Stress shielding is known to occur around rigidly fixed implants. There are no major complications such as infection or pain at an average of New Anatomic Design Features Contouring of the medial side of the head has been further defined to track against the lateral side of the ulna.

And the design changed from nonanatomical implants to anatomic design that attempts to replicate the variable shape of the native radial head. Late results in fractures of the radial head treated by excision. Monobloc radial head prostheses in complex elbow injuries: The average proximal radial migration on the affected side was 0.

Combinations head and stem combinations. The Acumed Anatomic Radial Head System is designed to provide an anatomic implant to replace the patient’s native radial head. On acumedd other hand, comminuted radial head fracture is associated with other injuries such as dislocation of the elbow, the coronoid process fracture, and the collateral ligament plste.

The benefit of the short length of the Plate Tack is that it is designed to not interfere with the drilling and placement of the proximal screws. In a direct radius-to-capitellum axial loading experiment, an anatomically designed radial head prosthesis had lower and more evenly distributed contact pressures than the nonanatomic implants that were tested.

Paired t test was used to compare between the affected and unaffected elbows in each patient.

Accurate Technology (Hong Kong) Limited

Designed in conjunction with Shawn W. Patients were monitored with serial examinations and radiographs. In addition to citing existing scholarly papers, we conduct ongoing clinical research and use this information for validation and continuous improvement to deliver the greatest ravial to our customers. All patients recovered the functional range of motion of the elbow.

The Acumed Anatomic Radial Head System provides a comprehensive solution that includes the first anatomically-shaped radial head prosthesis on radiao market and is equipped with the tools needed to restore the patient’s heac in a radial head replacement surgery. The system offers standard head and stem combinations, including five left- and five right-specific head options, five stem diameters, and five collar heights.

By use of a thin flexible pressure transducer, contact pressures and areas were measured for the native radial head, an anatomic implant, a nonanatomic circular monopolar implant, and a bipolar nonanatomic implant.
