A year-old man, right elbow; radiographic result 5 years after olecranon fracture and coronoid fracture fixed with screw and radial head replacement A, Anteroposterior view; B, Lateral view. On the other plage, comminuted radial head fracture is associated with other injuries such as dislocation of the elbow, the coronoid process fracture, and the collateral ligament disruption.
There were no the distal radio-ulnar degeneration. 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.

This study was performed on 12 patients with traumatic elbow fracture and instability between and of whom 12 were reviewed at a mean follow-up of A variety of implants have been used to replace the radial head.
Six patients had an associated elbow ligament injury and three patients had an associated coronoid fracture. This is different from other stem that causes high contact pressure on the opposing articular cartilage or bone cement [ 9 ].
Comminuted radial head fractures treated by the Acumed anatomic radial head system
The joint capsule and annular ligament acmued sutured without special ligament reconstruction. Radial head replacement with the MoPyC pyrocarbon prosthesis. J Bone Joint Surg Am. Three patients had 10 degrees of average flexion contracture. Methods We reviewed charts and radiographs of 86 cases from 79 patients with radial head implants from both primary and revision surgeries between and Resection of the radial head after Mason type-III fractures of the elbow: Radius Retractor – Designed to help elevate the radius, this tool may assist during reaming, trialing, and insertion of the implant.
Patients were monitored with serial examinations and radiographs. By providing the patient with an anatomical prosthesis, wear on the capitellum is theoretically reduced due to the improved biomechanics and balancing within the elbow.
Determine head diameter by placing the resected head into the sizing pockets on the impactor base.

If the radial head fracture associated with medial or lateral ligament rupture, we used the anchor to reconstruct the stability of the ligament. There are no major complications such as infection or pain at an average of Janssen RP, Vegter J. Between January and December12 patients six men and six women Table acumwd with radial head comminuted fractures were treated by radial head replacement of the Acumed anatomic radial head prosthesis system.
The dish depth increases with head diameter, which is designed to help improve radiocapitellar wear characteristics over the current-generation Acumed Anatomic Radial Head. If between sizes, select the smaller diameter. The Radial Head Plating System may be combined with any of the Acumed anatomic radial head plat systems and may be found at the bottom of the tray.
The plste stems accommodate a resection window of 9 mm—17 mm. Email Updates Yes, please send me updates by email. These radiak accommodate a resection window of 19 mm—28 mm.
Radiographic measurement revealed that average lateral ulnohumeral space on the affected side was 2.
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 ]. The Long Stem Resection Guide is used to ackmed the length of resection, which corresponds to stem diameter. Open reduction and internal fixation of radial head fractures. On the other hand, comminuted radial head fracture is often associated with other injuries such as dislocation of the elbow, the coronoid process, the collateral ligament disruption, interosseous membrane and radio-ulnar instability.
Paired t test was used to compare between the affected and unaffected elbows in each patient.
Radial Head Plating System
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, Acumec. We saw stress shielding with all stem types: Support Center Support Center.
Author information Article notes Copyright and License information Disclaimer. The most important cause of failure of internal fixation has been the inability to achieve rigid internal fixation [ 11 ].
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 effect of prosthetic radial head geometry on the distribution and magnitude of radiocapitellar joint contact pressures.
Journal Abstract Objective Stress shielding is known to occur around rigidly fixed implants. Many clinical and biomechanical studies showed that the radial head has been an afumed stabilizer of the elbow and forearm. The prosthesis that best mimicked native contact behavior was the anatomical radial head prototype 2 owing to its design for radiak with the capitellum, the lateral trochlear ridge, and the sulcus between.
Anatomic Radial Head Solutions
If the coronoid separated from the trochlea, it is indicated that radial head prosthesis collar is too large. None of the elbows had symptoms or signs of instability at the final evaluation. Insert stem hesd assembly into the bone canal and sequentially increase the height by inserting the end of the gauge under the head of the assembly, until the head reaches the capitellum. Metallic radial head arthroplasty improves valgus stability of the elbow.
Past designs of radial head prostheses have had a round radial head component. Clin Orthop Relat Res. A year-old man, right elbow; comminuted radial head fractures, undisplaced olecranon fracture and coronoid fracture, A, Anteroposterior view; B, Lateral view. So in these cases, radial head replacement should be considered, particularly associated with coronoid process fracture and ligament injuries of the elbow. Statistical analysis The flexion and extension, supination and pronation range of motion, and the lateral and medial ulnohumeral space, proximal radial migration were analyzed and compared.
In all cases, a P value of radkal. The unaffected elbow side in each patient was selected as a control group.
