Metallic Radial Head prosthesis

The purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.

Treatment of a fracture to the radial head depends on the severity of the damage.

A retrospective review of a trauma database was performed from 2007 to 2011. Under an IRB approved protocol, we used billing records to identify adult patients (age 18 or greater) who underwent radial head prosthesis removal as an inclusion criterion. A total of 14 patients including 6 women and 8 men with 14 radial head prostheses met the inclusion criteria and had complete follow-up data. There were no exclusion criteria. Three surgeons performed the prosthesis removals at a single institution.

Tips/Tricks to treat radial head fractures:

Physiotherapy should start as soon as possible after your radial head excision surgery.

Your physiotherapy will include:


After radial head excision your elbow will be considerably unstable and weak which will significantly affect function in your elbow and hand.

Arthroscopic removal of the failed silicone radial head prosthesis.

Inflammatory arthritis after failure of silicone rubber replacement of the radial head.

The purpose of this study was to 1) describe the preoperative complaints, 2) radiographic findings, and 3) postoperative outcome in patients who underwent radial head prosthesis removal.

Reported etiologies leading to prosthetic radial head removal were mechanical or technical issues, namely, prosthesis dislocation, mechanical impingement, overstuffing, or intermittent slippage of the bipolar radial head prosthesis (-). Painful loosening and polyethylene wear with painful synovitis were other additional primary concerns (, ). Prosthesis removal has also been described as part of elbow contracture release surgery, and following joint infections (). However, there is a paucity of reported complications following radial head arthroplasty in the literature and a shortage of published reports outlining complications that resulted in implant removal ().

A floating prosthesis for radial-head fractures.

Physiotherapy after radial head excision is crucial to ensure the success of the surgery, prevent the likelihood of any future problems and to help you achieve the return of full or near to full function within the elbow joint.

Symptomatic failure of snap-on bipolar radial head prosthesis.






Radial head excision is a surgical procedure that involves the removal of the radial head after severe damage following trauma such as radial head fracture or as a result of degenerative changes associated with arthritis.

Malpositioning of radial head prostheses: an in vitro study.

Results and Conclusion: Satisfactory clinical results can be anticipated when a radial head prosthesis is used for the correct indications and when a systemic approach is undertaken to ensure proper sizing.

Loss of flexion after radial head replacement.

This is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. The average time between implantation and removal was 23 months (range from 2 weeks to 12 years, median 12 months).

Reference points for radial head prosthesis size.

The major pitfall when using a metallic radial head prosthesis is the insertion of a longer implant, which results in overstuffing of the radiocapitellar joint.

Materials and Methods: The main indication for a metallic radial head prosthesis is a comminuted fracture that is not amenable to reconstruction, and particularly if it is associated with complex elbow injuries.
