RESUMO
Radial head displaced irreparable fracture is an indication for prosthesis; it becomes elective also when there are associated injuries of the skeletal and ligamentous stabilization systems. A retrospective study was conducted to evaluate the functional and radiographic results in 10 patients (mean age 39.6 yrs; minimum 20, maximum 80) submitted to radial head replacement. There were 4 Mason-Johnston type IV Rochwerger subtype "b" fractures, 7 type III fractures (1 associated with an Essex-Lopresti injury and 1 with fracture of the ulnar proximal metaepiphysis). Mean follow-up was 24.6 months (minimum 18, maximum 32). Postoperative functional evaluation of the elbow and ipsilateral wrist was carried out using the ESSSE/SECEC form (mean score 80.7/100; minimum 63, maximum 96) and the PRWE (mean score 11.1; minimum 0, maximum 36) respectively. Radiographically there were postoperative calcifications in 30% of cases and periprosthetic lucency in 40%. The results of this study encourage the use of a metal prosthesis, but a longer follow-up is needed for a better evaluation.

Reported here are the results obtained for 216 prosthetic implants in which cementless arthroplasty and a modular neck were used. The advantages to using this method are related to the fact that it may be adapted to a variety of anatomical conditions.
