Mason I fractures of the radial head, often considered simple, can lead to complications like osteoarthritis and instability. Close follow-up is crucial for early detection and prevention of long-term issues.
Area of Science:
- Orthopedic surgery
- Traumatology
Context:
- Mason I fractures of the radial head are typically managed nonoperatively with expected good outcomes.
- However, this study investigates complications arising from these fractures.
Purpose:
- To present a case series of patients experiencing complications following Mason I radial head fractures.
- To discuss diagnostic and therapeutic approaches for these complications.
Summary:
- A review of 16 patients revealed complications including osteoarthritis with stiffness and loose bodies (10 patients), posterolateral rotatory instability (4 patients), combined medial and lateral instability (1 patient), and symptomatic hypertrophic plica (1 patient).
- Mean age was 37 years, with a mean of 25 months between initial trauma and subsequent surgery for complications.
Impact:
- Findings suggest a need to re-evaluate the management of Mason I fractures.
- While conservative treatment remains primary, vigilant monitoring is essential to mitigate risks of stiffness, chronic instability, and osteoarthritis.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
