Therapeutic Results

Radial head replacement should be indicated in all cases of radial head fractures when open reduction and internal fixation is anticipated to be difficult or impossible. Although excellent therapeutic results have been ob­tained, this procedure, like any other surgical procedures, may be associated with severe complications, includ­ing contractures, ossification or aseptic synovitis. In these cases, removal of the prosthetic radial head has al­ways been a safe and popular solution producing a satisfactory clinical outcome. However, we present the case of a patient in whom the prosthesis was left in place, but the polyethylene head was replaced with a metal-covered head. The decision to perform this procedure was taken intraoperatively.

Patient Variables

Background: The decision between radial head arthroplasty and open reduction internal fixation in the context of a terrible triad elbow fracture-dislocation is debated. This study investigated both surgeon and patient factors associated with surgeons’ recommendations to use arthroplasty. Methods: One hundred fifty-two surgeon members of the Science of Variation Group participated. Surgeons were asked to complete an online survey that included surgeon demographics and 16 patient scenarios. The patient scenarios were randomized using 2 patient variables and 2 anatomical variables. Multilevel logistic mixed regression analysis was performed to identify surgeon and patient variables associated with recommendations for radial head arthroplasty. Results: We found that radial head replacement was recommended in 38% of the scenarios. Scenarios with older patients, with fractures of the whole head, and those involving 3 fracture fragments were independently associated with radial head replacement. Conclusion: We found that most surgeons recommended radial head fracture fixation rather than arthroplasty. Surgeons were more likely to recommend fixation for younger patients with partial articular fractures or with fractures with 3 or fewer fracture fragments. It seems that surgeons are uneasy about using a prosthesis in a young active patient.

Type 3

The shape and size of the radial head is highly variable but correlates to the contralateral side. The radial head is a secondary stabilizer to valgus stress and provides lateral stability. The modified Mason–Hotchkiss classification is the most commonly used and describes three types, depending on the number of fragments and their displacement. Type 1 fractures are typically treated conservatively. Surgical reduction and fixation are recommended for type 2 fractures, if there is a mechanical block to motion. This can be done arthroscopically or open. Controversy exists for two-part fractures with >2 mm and <5 mm displacement, without a mechanical bloc as good results have been published with conservative treatment. Type 3 fractures are often treated with radial head replacement. Although radial head resection is also an option as long-term results have been shown to be favourable. Radial head arthroplasty is recommended in type 3 fractures with ligamentous injury or proximal ulna fractures. Failure of primary radial head replacement may be due to several factors. Identification of the cause of failure is essential. Failed radial head arthroplasty can be treated by implant removal alone, interposition arthroplasty, revision radial head replacement either as a single stage or two-stage procedure.
