FUNCTIONAL OUTCOME OF TYPE III AND IV RADIAL HEAD FRACTURES TREATED BY RADIAL HEAD PROSTHESIS

Abstract

INTRODUCTION: Fractures affecting the radial head and neck constitute approximately 1.7-5.4% of all fractures and represent about 33% of all elbow fractures. Fractures of the Mason Type III and IV are complex and management is controversial. The aim of this study was to determine the functional outcomes of radial head replacement in Mason III and IV radial head fractures in adults
MATERIALS AND METHODS: This retrospective study measured the outcomes of patients who had radial head replacement after a Mason III or IV fracture. This retrospective study included 30 patients of type III and IV radial head and neck fractures according to Mason's classification. This retrospective study included 30 patients of type III and IV radial head and neck fractures according to Mason's classification. Data was collected from hospital records and interviews and examinations were conducted with participants by appointment. Prior to developing the Data Sheets, a review of the literature was done to identify possible important demographic factors. The Mayo elbow performance index was found to be most useful in assessing functional outcomes.
RESULTS: Among the total of 30 cases, 19 (63.3%) cases were below the age of 40, while 11 (26.7%) cases were over 40. The average age was 35.8 years. The female population outnumbered the male population. There was significant improvement in flexion, extension, pronation, and supination at the second and sixth post-op weeks. 20 cases (66.7%) had MEPI score (Mayo Elbow Performance Index) >90 which indicates excellent result, 8 cases (26.6%) had MEPI score 75-89 which is good result and 2 cases (6.7%) had MEPI score 60-74 which indicates fair result.
CONCLUSION: It is concluded that that radial head prosthesis provides good functional results in Modified Mason's type III and IV radial head fractures, with a decreased complication rate and earlier mobilization.
