Which is the Best Solution for Achieving Maximal Interfragmentary Compression of the Scaphoid Fractures - One or Two Herbert Screws?

CONCLUSIONS This study of 72 patients in whom patients with similar fracture geometry were separated into two groups fixed by one HBS and fixed by two HBS. Analysis of the results demonstrate that osteosynthesis with two HBS creates greater fracture stability. The proposed algorithm for fixation of acute scaphoid fractures using two HBS is achieved by simultaneously placing the screw along the axial axis and perpendicular to the fracture line. The stability is improved by the equal distribution of the compression force on the entire fracture surface. Key words: scaphoid fractures, Herbert screw, two screws fixation.PMID:36907581
