radial-head-arthroplasty
A 45-year-old woman falls onto an outstretched hand. Radiographs reveal a comminuted radial head fracture with more than 3 articular fragments and greater than 2mm of displacement. The elbow is stable on valgus stress testing. CT confirms the fracture involves the entire head with involvement of the radial neck. The lateral collateral ligament complex appears intact. **According to the Mason-Johnston classification, what is the fracture grade and MOST appropriate management?**
