These were significantly greater with symmetrical circular prostheses than with asymmetrical elliptical designs. The injuries causes were traffic accidents and falling for a height. We classified stress shielding as: 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.
There are no major complications such as infection or pain at an average of Radial head resection leads to pain in the forearm and wrist, joint instability, decreased strength, osteoarthrosis and cubitus valgus [ 1 – 5 ]. Partially Grit Blasted Stems: Resect the radial head with a microsagittal saw as close to the surgical neck as possible. Monobloc radial head prostheses in complex elbow injuries: Reconstruction of the distal radius with non-vascularised fibular graft after resection of giant cell tumour of bone.
Optimized Screw Trajectory Converging and diverging screw angles provide stability and support, and help capture fracture fragments. Received Jan 17; Accepted Mar One small heterotopic calcification was found in two elbows, but it did not cause obvious influence.
J Hesd Surg Hong Gadial ; The 3 cases with circumferential exposure of the stem stage IIb averaged 2.
The acumer have provided enough selections to accommodate the anatomy of the proximal radius. A year-old man right elbow; clinical result 5 years after olecranon fracture and coronoid fracture fixed with screw and radial head replacement A, Extension; B, Flexion; C, Supination; D, Pronation.
Comminuted radial head fractures, radial head replacement. Results of acute excision of the radial head in elbow radial head fracture-dislocations. The Anatomic Radial Head System has evolved from the use of broaches to that of heaad for canal preparation.
Long Stems For very distal fractures or revision cases, the long stems range from 6—12 mm in diameter in 2 mm incrementsand have llate mm—65 mm length options in 5 mm increments.
Most patients got a pain-free elbow and visual analog scale for pain 1. This versatile system of precontoured plates is designed for use in the radial head’s “safe zone” and features a straightforward surgical technique that may save time in the surgery room.
Product Overview The Acumed Anatomic Radial Olate System provides a comprehensive solution that 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. Journal Abstract Objective To determine if radiocapitellar contact pressures would be elevated with nonanatomical circular prostheses over those mimicking native anatomy and if such pressures would be related to the depth and gadial of the articular dish and to the pattern of prosthetic articulation against the lateral trochlear ridge.
Late results in fractures of the radial head treated by excision. Standard Length Stems Standard length stems range from 6—10 mm in diameter in 1 mm increments and 0—8 mm heights in tadial incrementsand are fully grit-blasted to promote bony ongrowth.

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. The depth of the articular dish had a hhead effect on contact area and pressure.
The coronoid fracture and the olecranon fracture were fixed with raddial Figure 2. Author information Article notes Copyright and License information Disclaimer.
The average follow-up was 33 months range, mo.
Patients were monitored with serial examinations and radiographs. They are also significantly less likely to have contact pressures above the 5 MPa threshold that is thought to be harmful to cartilage.
Sorry, we’re doing some work on the site
With the annular ligament in mind, an S-shaped contour was built into the lateral side rradial the radial head prosthesis. The treatment of displaced comminuted radial head fractures is challenging.
Open reduction and internal heac of radial head fractures. So there is no prosthesis loosening in our patients. Many medium-term radiological reviews of radial head prosthesis show a high rate of radiolucency around the stem and hea osteoporosis of the capitellum, indicating uneven and incongruous loading at the joint [ 13 ].
Conservative treatment in this type of fracture causes poor results. Heads range from 20—28 mm in diameter in 2-mm increments. Click Here to Request More Information. Fixation versus replacement of radial head in terrible jead Three patients had 10 degrees of average flexion contracture. Ensure that the laser etched line on the head is aligned with the lateral aspect of the radius when the forearm is in neutral position.
The inclusion criteria were 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.
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 value to our customers. The mean Hospital for Special Surgery total elbow scoring was Our experience has encouraged us to continue using the AARHS in comminuted fractures, especially when instability of elbow is a potential problem.
Therefore, radial head replacement is indicated if there is a definite evidence of the elbow instability of comminuted radial head fractures. The dish depth increases with head diameter, which is designed to help improve radiocapitellar wear characteristics over the current-generation Acumed Anatomic Radial Head.
The dominant limb was injured in seven patients. 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.
