Zhang Y, Shao Q, Yang C, et al. - This study was undertaken to use finite element analysis to explain the advantages and disadvantages of ulnar-side locking plate fixation compared with dorsal-side locking plate fixation and its screw arrangement in the treatment of ulnar head fractures. Researchers constructed FE models of the ulnar head fracture and the models of the ulnar-side locking plate and dorsal-side plate with two or three distal screws. The data demonstrated that ulnar-side locking plates resulted in lower stress distribution in the plate and better stability than dorsal-side locking plates for ulnar head fracture fixation. The findings revealed that adding an additional screw to the ulnar head could increase the stability of the fixation system and provide an anti-torsion function. This research needs clinical confirmation of its practicality in the treatment of ulnar head fractures.
