Bipolar Radial Head Prosthesis »

ARTICLE IN PRESS - Midwest Orthopaedics at Rush.

Radial head arthroplasty is currently accepted for the treatment of unreconstructible radial head fractures in cases with elbow instability.6, 12, 15, 23, 24 Biomechanical studies have demonstrated that a metallic monopolar radial head prosthesis can restore valgus stability of the elbow and longitudinal stability of the forearm.11, 14 The bipolar. Conclusion: Bipolar radial head prosthesis with a smooth cementless stem effectively restores elbow sta- bility and function after comminuted radial head fractures with or without concomitant elbow instability. Radial head arthroplasty is indicated when the secondary stabilizing function of the radial head is required and reconstruction of the radial head is not feasible. 22 Generally, this is the case with Mason type 3 radial head fractures and more complex fracture dislocations. 22 Theoretically, the bipolar designs reduce abrasion of the capitellar cartilage and stress at the implant-to-cement and cement-to-bone interfaces.

The Acumed Anatomic Radial Head Solutions 2 system is designed to provide an anatomic implant to replace the patient’s native radial head. Designed in conjunction with Shawn W. O’Driscoll, MD, PhD, the Acumed Anatomic Radial Head Solutions 2 system includes 924 head and stem combinations and system-specific instrumentation to help streamline the surgeon’s experience in the operating room. Right bipolar radial head prosthesis with eventual prosthesis loosening: 57 year-old woman with radial head prosthesis and capitellar suture anchor. In 2011 she had a right elbow dislocation with a comminuted radial head fracture. A bipolar radial head prosthesis was placed to treat post-traumatic arthritis. Initial radiographs obtained in 2014. Bipolar radial head prosthesis represents a suitable option for acute treatment of unreconstructable radial head fractures, either isolated or associated with elbow dislocation and in the absence. OBJECTIVE. The purpose of this study is to provide a radiographic outcome assessment of radial head arthroplasty in correlation with clinical outcomes and to determine whether there is an association between certain patient factors and clinical and radiographic outcomes.

Brinkman JM, Rahusen FT, de Vos MJ, Eygendaal D. Treatment of sequelae of radial head fractures with a bipolar radial head prosthesis: good outcome after 1–4 years follow-up in 11 patients. Radial Head Replacement Coronoid Fracture ORIF Forearm Both Bone Forearm Fracture ORIF Distal Radius Extra-articular Fracture ORIF with Volar Appr. Unrepairable comminuted fractures of the radial head Mason type III or type IV have poor outcomes when treated by open reduction and internal fixation. Radial head resection has been proposed as good option for surgical treatment, while in the last decades, the development of technology and design in radial head prosthesis has increased efficacy in prosthetic replacement. ABSTRACTPurpose: To compare clinical outcomes of unipolar and bipolar radial head prosthesis in the treatment of patients with radial head fracture. Materials and Methods: Medline, Cochrane, EMBASE, Google Scholar databases were searched until April 18, 2016 using the following search terms: radial head fracture, elbow fracture, radial head arthroplasty, implants, prosthesis, unipolar, bipolar.
