Abstract
Introduction The use of the one-third tubular plate as a hook plate for treating ankle fractures has been considered an effective alternative for osteosynthesis in cases involving small bone fragments, multifragmentary fractures, or patients with poor bone quality. This technique was first documented in 1948. The one-third tubular plate has been successfully employed in fractures at various anatomical sites. Today, this plate is available in titanium and stainless steel with a thickness of 1.0 mm, making it suitable for areas with minimal soft tissue coverage. After two decades of use, this article presents the one-third tubular plate, used as a hook plate, as a viable and effective alternative for treating ankle fractures.
Material and Methods A descriptive retrospective study included 83 patients over 20 years. Of these, 57.84% were male, and their ages ranged from 22 to 85 years. Exposed fractures accounted for 9.6%, with 50% classified as Grade II, 38% as Grade IIIA, and 12% as Grade IIIB. All patients underwent open reduction and osteosynthesis within the first 24 hours.
Results Fracture consolidation was observed in 81.93% of cases at 12 weeks, in 4.8% between 13 and 16 weeks, and 9.6% after 16 weeks. In 3.6% of cases, consolidation was delayed, occurring between 20 and 24 weeks. Complications were reported in 3.61% of cases. Additionally, one patient developed ankle osteoarthritis and only 2.49% required implant removal.
Conclusion The results demonstrate that the one-third tubular plate used as a hook plate is an effective and recommended option for ankle fracture surgery, with favorable functional outcomes, high consolidation rates, and low complication rates.
