Biomechanical Comparison of Proximal Radius Locking Plates Under Dynamic Loading

Mar 8, 2012 | Upper Extremity

Proximal radius fractures are commonly encountered in general orthopaedic and upper extremity subspecialty practices. The surgical treatment of these fractures includes the anatomical reconstruction and stable fixation of the proximal radius to achieve early recovery of elbow function, reducing the complication rate. These goals are often obtained in cases showing no or minimal comminution. However, due to high complication rates in the management of complex and highly comminuted fractures, locked plating systems are being utilized with increasing frequency. Specifically, 20% of all elbow trauma is associated with radial head/neck fractures, which historically has been treated with excision or prosthetic replacement. Further, recent literature advocates radial head preservation whenever possible in young, active patients. This study compares the biomechanical properties of two proximal radius locking plate designs under dynamic loading to determine their ability to withstand the forces which occur during fracture healing and early postoperative rehabilitation.
