Between January and December afumed, 12 patients six men and six women Table 1 with radial head comminuted fractures were treated by radial head replacement of the Acumed anatomic radial head prosthesis system.
Past designs of radial head prostheses have had a round radial head component. The 3 cases with circumferential exposure of the stem stage IIb averaged 2. Determine head diameter by placing the resected head into the sizing pockets on the impactor base. The dish depth increases with head diameter, which is designed to help improve radiocapitellar wear characteristics over the previous generation Anatomic Radial Head. These were significantly greater with symmetrical circular prostheses than with asymmetrical elliptical designs.
Low-profile Design Screws sit flush with the plate for minimized hardware prominence. The system offers standard head and stem combinations, including five left- and five right-specific head options, five stem diameters, and five collar heights. Partially Grit Blasted Stems: These stems accommodate a resection window of 19 mm—28 mm. 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 radual tray to allow for ease of preoperative assessment.
There was no pain in the forearm or wrist, and there was no complex regional pain syndrome. The system offers a straightforward solution when the radial head is salvageable.
A year-old man, right elbow; comminuted radial head fractures, undisplaced olecranon fracture and coronoid fracture, A, Anteroposterior view; B, Lateral view. Multiple Collar Heights To restore radial length. The mean Hospital for Special Surgery total elbow scoring was Hand N Y ; 6: The mean DASH score was There plte humero-ulnar arthritwas in one elbow.
Email Updates Yes, please send me updates by email. 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. Peak contact pressures were also measured and were radiql elevated with all prostheses tested. The Acutrak 2 Mini and Micro Headless Compression Screw instrumentation is also found at the bottom of each radial head replacement system tray, expanding the treatment options for the surgeon.
The treatment of displaced comminuted radial head fractures is challenging.
Stress shielding never extended to the bicipital tuberosity, and there were no cases of impending mechanical failure. The rzdial provides a comprehensive solution for radial head replacement. Contoured Lateral Surface Improves interface with the annular ligament.
There was no dislocation of the radial prosthetic head. Because the radial head played one critical acumee in the elbow stability, many orthopedic surgeons suggest preserving the radial head during fracture treatment. Radial head acuumed for radial head fractures. The stem of the AARHS is uncemented and fixed through a tight press fit, so it can reduce the incidence of loosening. If between sizes, select the smaller diameter.
The range of elbow inflexion was recorded and muscle strength was measured with a dynamometer. The average proximal radial migration on the affected side was 0. Fixation versus replacement of radial head in terrible triad: Many radial head designs have been used currently, but little studies showed that one design is better than another.
For isolated fractures of the radial head and neck, without ligament injury, postoperative early motion is commenced in flexion and extension as well as pronation and supination.
All operations were performed using the Acumed anatomic radial head prosthesis system within ten days of injury.

A radial head replacement is more effective in comminuted radial head fractures. At the same time, the coronoid process is one standard to assess the radial head prosthesis size. Many medium-term radiological reviews of radial head prosthesis show a high rate of radiolucency around the stem and also osteoporosis of the capitellum, indicating uneven and incongruous loading at the joint [ 13 ].
Our study showed that the mid-term results of the clinical and radiological outcome of AARHS are better. In conclusion, the radial head replacement with the AARHS can provide effectively stability and good clinic results at the middle term following up. Standard Length Stems 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.
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 contour of the articular dish and to the pattern of prosthetic articulation against the lateral trochlear ridge.
Each prosthesis and specimen combination was loaded in neutral rotation and maximal extension with a custom testing apparatus while measuring contact areas and pressures using thin-film pressure sensors.
Select the collar reamer that matches the stem diameter determined by the broach. Combinations head and stem combinations. J Shoulder Elbow Surg.

Radial head resection has been associated with long-term complications, including wrist and forearm pain, valgus elbow deformity, degenerative osteoarthrosis, and decreased strength [ 45 ].
