RESUMO

Background: The functional stability of the elbow joint can be effectively restored in acute care for comminuted radial head fractures (RHFs) complicated with secondary ligamentous or bony injuries through the use of a metallic radial head implant. Aims and Objectives: This study aimed to evaluate the efficiency of modular metallic radial head implant EVOLVE® prosthesis in restoring the functional range of motion and elbow joint stability in acute care. Materials and Methods: A prospective observational study was conducted in the department of orthopedics at a tertiary-level care hospital in North India from April 2021 till March 2022. All consecutive patients above 18 years of age, with comminuted closed RHF, were included in the study. All underwent modular metallic head radial head implantation. The Mayo Elbow Performance Score (MEPS) was used to measure functional outcomes. Results: We observed that MEPS at 1-month follow-up was 81.54 ± 11.18, which improved significantly at the 3rd-month follow-up to 87.24 ± 12.42 (P < 0.001). On the next follow-up at the 6th month, MEPS increased further to 92.14 ± 7.36, P < 0.001. At the final follow-up at the 6th month, MEPS was graded as excellent for 80%, good for 12%, fair for 4%, and poor for 4%. One patient had complex regional pain syndrome and one had joint stiffness. Conclusion: The use of a modular radial head prosthesis has shown promise in treating comminuted RHF by re-establishing elbow joint stability in acute setting. This study demonstrated promising short-to-midterm results for the modular radial head arthroplasty.

RESUMO

Introduction: Radial head and neck fractures are one of the commonly encountered traumatic injuries. Commonlyproposed management includes radial head prosthesis implant or open reduction and internal fixation dependingon type of injury. Radial head measurements are very valuable in reconstruction of radial head. Appropriateanatomy of radial head will help in preventing postoperative stiffness and enable good rehabilitation.Aims and objectives: To estimate and compare radial head parameters of proximal end of right and left radii.Materials and Methods: Radial head measurements -Height of radial head in medial (MH) and lateral (LH) side,Antero posterior diameter (APD) and transverse diameters (TD) of radial head, Thickness of ventral (TVC), lateral(TLC) and dorsal (TDC) curves and depth of articular facet (D) were measured with the help of digital caliper.Statistical analysis was done using SPSS software. Difference in sides was measured using independent sampleT test (p value < 0.05 considered significant).Results: Mean values of Radial head measurements were APD:19.81mm, TD:18.925mm, MH:9.795mm,LH:7.735mm,TVC:5.05,TDC:3.695,TLC:3.64,D:1.735.There was difference in values of TLC between right and leftsides.Conclusion: Mean values of radial head measurements were comparable with previous studies. Side differenceshould be considered while implanting prosthesis on affected side.
