Anatomic Radial Head System
The average follow-up was 33 months range, mo. The average proximal radial migration on the affected side was 0. Indicate proper alignment with the lateral aspect of the radius when the forearm is in neutral position. plzte
If the coronoid separated from the trochlea, it is indicated that radial head prosthesis collar is too large. Anatomical designs are statistically more likely to mimic normal contact with the lateral trochlear ridge and its adjacent sulcus than circular prostheses.
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. Published by Elsevier, Inc. In addition to citing existing scholarly papers, we conduct ongoing clinical research and use this information for validation and continuous improvement to deliver the poate value to our customers.
Accurate Technology (Hong Kong) Limited
Radial head resection leads to pain in the forearm and wrist, joint instability, decreased strength, osteoarthrosis and cubitus valgus [ 1 – 5 ]. Combinations gead and stem combinations. The range of elbow inflexion was recorded and muscle strength was measured with a dynamometer.
Email Updates Yes, please send me updates by email. All patients were immobilized initially in a long arm splint in 90 degrees of flexion with neutral rotation. Open in a ackmed window.
The standardized elbow radiograph were taken and used to detect the ossification and osteoarthritic change, the prosthesis stability and change of the distal radio-ulnar joint. Long Stems For very distal fractures or revision cases, the long stems range from 6—12 mm in diameter in 2 mm incrementsand have 50 mm—65 mm length options in 5 mm increments.
Comminuted radial head fractures treated by the Acumed anatomic radial head system
Insertion Depth Laser Mark: K-wire holes are included in the plate for provisional fixation distally, and specially designed plate tacks may be used for provisional fixation proximally. Past designs of radial head prostheses have had a round radial head component. Between January and December12 patients six men and six women Table 1 with radial head comminuted fractures were heda by radial head replacement of the Acumed anatomic radial head prosthesis system.
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. These stems accommodate a resection window of 19 mm—28 mm. Radiographic measurement revealed that average lateral ulnohumeral space on the affected side was 2.
Low-profile Design Screws sit flush with the plate for minimized hardware prominence. The system offers standard head and stem combinations, including plqte left- and five right-specific head options, five stem diameters, and five collar heights. The 3 cases with circumferential exposure of the stem stage IIb averaged 2. A floating prosthesis for radial-head fractures. Click Here to Request More Information. Converging and diverging screw angles provide stability acued support, and help capture fracture fragments.
Fixation versus replacement of radial head in terrible triad: Open reduction and internal fixation of radial head fractures. Four long stems range from 50 mm to 65 mm in length 5 mm increments and 6 mm to 12 mm in diameter 2 mm increments. The fluted stem of the AARHS can provide rotational stability and rxdial blasted stem surface promotes bony ongrowth.
The dish depth increases with head diameter, which is designed to help improve radiocapitellar wear acumd over the current-generation Acumed Anatomic Radial Head. Statistical analysis The flexion and extension, supination and pronation range of motion, and the lateral acmed medial ulnohumeral space, proximal radial migration palte analyzed and compared. Despite there is a significant difference between the affected and unaffected elbow in range of movements, the patients recovered the functional range of motion of the elbow.
National Center for Biotechnology InformationU. In addition, collar reamers are designed to create a perpendicular neck surface for the stem collar.
The Acumed Anatomic Radial Head System provides a comprehensive solution nead includes the first anatomically-shaped radial head prosthesis on the market and is equipped with the tools needed to restore the patient’s anatomy in a radial head replacement surgery. This is different from other stem that causes high contact pressure on the opposing articular cartilage or bone cement [ 9 ].
Lister’s tubercle may also be used as rasial landmark for laser mark orientation. Ensure that the laser etched line on the head is aligned with the lateral aspect rzdial the radius when the forearm is in neutral position. Internal fixation is difficult in many cases and sometimes leads to implant failure [ 67 ]. J Shoulder Elbow Surg. Compared with other studies of a similar size, our clinical results with all excellent results at medium-term follow-up is better than other studies [ 12 – 18 ].
More than a decade of research and experience has influenced key refinements to the anatomic properties of the prosthesis.
