Lag screw fixation of sagittal navicular bone fractures in five horses.

This research paper presents a study on using lag screw fixation to treat sagittal fractures of the navicular bone in horses, with the treatment resulting in positive healing outcomes in all five cases.

Objective of the Research

• The aim of the study was to investigate the effectiveness of using lag screw fixation to treat sagittal fractures in the navicular bone of horses. The authors of the research sought to assess the efficacy of this method in promoting fracture healing and avoiding unnecessary callus formation.

Procedure Used

• The lag screw fixation method was used in the treatment. This required intra-operative radiographic monitoring and the use of a specifically designed guide apparatus which helped in the accurate implantation of the screw along the transverse axis of the navicular bone.

Results of the Research

• The results showed that the use of internal fixation led to a progressive radiographic reduction of the fracture zone.
• All five horses treated using this method experienced positive healing outcomes, with the fractures successfully uniting without any unnecessary callus formation.

Conclusions of the Study

• Based on the findings, the authors concluded that the lag screw fixation method can effectively treat sagittal fractures of the navicular bone in horses.
• They further recommended its use as it not only promotes healing but also avoids unwanted callus formation, which can be detrimental to the healing process.
