Influence of bone cements on bone-screw interfaces in the third metacarpal and third metatarsal bones of horses.
Abstract: To compare biomechanical strength, interface quality, and effects of bone healing in bone-implant interfaces that were untreated or treated with calcium phosphate cement (Ca-cement), magnesium phosphate cement (Mg-cement), or polymethylmethacrylate (PMMA) in horses. Methods: 6 adult horses. Methods: 4 screw holes were created (day 0) in each third metacarpal and third metatarsal bone of 6 horses. In each bone, a unicortical screw was placed in each hole following application of Ca-cement, Mg-cement, PMMA, or no treatment (24 screw holes/treatment). Screws were inserted to 2.82 N m torque. Horses were euthanized and bones were harvested at day 5 (16 screw holes/treatment) or day 182 (8 screw holes/treatment). Radiography, biomechanical testing, histomorphometry, and micro-computed tomography were performed to characterize the bone-implant interfaces. Results: Use of Mg-cement increased the peak torque to failure at bone-implant interfaces, compared with the effects of no treatment and Ca-cement, and increased interface toughness, compared with the effects of no treatment, Ca-cement, and PMMA. Histologically, there was 44% less Ca-cement and 69% less Mg-cement at the interfaces at day 182, compared with amounts present at day 5. Within screw threads, Ca-cement increased mineral density, compared with PMMA or no treatment. In the bone adjacent to the screw, Mg-cement increased mineral density, compared with PMMA or no treatment. One untreated and 1 Ca-cement-treated screw backed out after day 5. Conclusions: In horses, Mg-cement promoted bone-implant bonding and adjacent bone osteogenesis, which may reduce the risk of screw loosening.

This research aims at comparing the strength, quality, and healing effects of bone-implant interfaces in horses that have been treated with different bone cements. The study found that the use of magnesium phosphate cement (Mg-cement) increased the strength and quality of bone-implant interfaces, hence the cement type can influence the likelihood of a screw loosening.
Methodology
- The study involved six adult horses, focusing on their third metacarpal and third metatarsal bones.
- In each bone, four screw holes were created, and a unicortical screw was placed in each hole following the application of calcium phosphate cement (Ca-cement), Mg-cement, polymethylmethacrylate (PMMA), or no treatment. A total of 24 screw holes were treated for each method.
- The screws were inserted with a torque of 2.82 N m.
- The horses were euthanized and the bones were collected on day 5 (for 16 screw holes per treatment) and day 182 (for 8 screw holes per treatment).
- Various tests such as radiography, biomechanical testing, histomorphometry, and micro-computed tomography were performed to observe the bone-implant interfaces.
Results
- The use of Mg-cement resulted in a marked increase in the torque to failure at the bone-implant interfaces as compared to no treatment and the use of Ca-cement. It also improved interface toughness against no treatment, Ca-cement, and PMMA.
- By day 182, 44% less Ca-cement and 69% less Mg-cement was recorded at the interfaces compared to amounts present on the 5th day.
- Calcium phosphate cement (Ca-cement) was found to increase mineral density within the screw threads when compared to PMMA or no treatment.
- In the bone adjacent to the screw, Mg-cement raised the mineral density as compared to PMMA or no treatment.
- One untreated and one Ca-cement-treated screw backed out after the 5th day.
Conclusions
- The research concluded that in horses, the use of Mg-cement could enhance bone-implant bonding and adjacent bone osteogenesis, which might contribute to reducing the risk of a screw loosening within the bone.
