- Fragile fractures, also known as osteoporosis fractures, insufficiency fractures, and senile fractures are a significant problem encountered by orthopedic surgeons. Calcium and vitamin D are essential for maintaining bone health and deficiencies in calcium and vitamin D are major risk factors for the development of osteoporosis. Sufficient amounts of calcium are also required for fracture-callus mineralization. Hence, compromised bone repair that is frequently observed in osteoporotic patients might be attributed to calcium and vitamin D deficiencies. Consequently, calcium and vitamin D supplementation represents a potential strategy for treating compromised fracture healing in osteoporotic patients.
There is some clinical evidence of the positive effect of supplementation in fracture healing and posttraumatic bone turnover, but research in this area is ongoing. Calcium and vitamin D should be the primary treatment of choice in osteopenic patients with an insufficiency of calcium and vitamin D and for the prevention of secondary osteoporotic fractures. Calcium and vitamin D can also be used as addition to other primary osteoporotic medications such as antiresorptive or bone-forming agents. The role of calcium and vitamin D in fracture healing and the therapeutic potential of calcium and vitamin D supplementation is summarized in this context.

- PURPOSE
The transversely oriented fracture lines are very difficult to reduce during operations, even after clear exposure of the fracture site, in acetabular fractures. The purpose of this study is to verify the quality of reduction between the different subtypes (transtectal, juxtatectal, and infratectal) of transverse fractures. This study also determined the proper type of clamps to use and the proper zone for achieving accurate reductions in Sawbones models.
MATERIALS AND METHODS
Six fractures in 3 different subtypes of transverse fractures were artificially created. Ten different reduction clamps were applied for reduction of the fractures. Twelve holes around the fracture were drilled for the maintenance of the clamps. The fracture displacements were measured at the extra-articular area and the intra-articular joint portion. The pictures of the intra-articular fracture displacements were taken by a camera and these were uploaded and analyzed by the TraumaCad® computer program (Brainlab).
RESULTS
The reduction quality was poor in order of transtectal, juxtatectal and infratectal. The intraarticular opening was more prominent in the transtectal subtype. The safe zone, when giving consideration of the neurovascular bundles, was a quadrilateral surface of the ilium. Drill holes are useful for maintenance of the reduction clamps. Reduction clamps with points (Weber clamp) were the best for maintenance and accurate reduction. Regarding the concerns of placement of clamps, the middle to posterior combination was the best. The upper hole among the posterior holes in the ilium was the most likely to well reduce the intra-articular opening.
CONCLUSION
Transtectal was the more complicated subtype in the aspect of reduction quality. The Weber type reduction clamp was the best for reduction by centrally located holes in the quadrilateral surface and posteriorly located iliac holes in transverse acetabular fractures. The upper hole, among the posterior holes in the ilium, was the best for reduction of the fracture displacements in the intraarticular portion of acetabulum.
