  abstract: This study was designed to determine the effect of 4 different methods of insertion on the stability of external splintage pins and to compare the bone holding ability of standard stainless steel pins to those coated with titanium. Fourteen Beagle dogs were divided into 3 groups for post-operative evaluations at 1 day, 2 weeks and 5 weeks. Dogs were treated with two fluorochromes, oxytetracycline and calcein, specific for new bone. The methods of insertion which were compared were: non-threaded (NT) pins inserted with a hand chuck, NT pins inserted with a low speed 300 RPM power drill, NT pins which were inserted with a hand chuck after predrilling and partially threaded (PT) pins which were inserted with a hand chuck after predrilling. Left femurs received stainless steel pins (SSP) while right femurs received titanium coated pins (TCP). Radiographs were taken preoperatively and, at intervals, post-operatively (PO) to evaluate pin positioning and interfacial tissue changes. After the dogs were sacrificed, the femurs were resected and freed of soft tissue to allow testing on a universal testing machine. After testing, the diaphyses were sectioned histologically processed, and one section from each interface was image analyzed for fluorescence. Interfacial shear strengths, an indication of stability, were determined for each interface. PT-SSP interfaces were more stable (p<.05) than NT-SSP interfaces at all 3 times PO. There were no differences (p>.05) between methods at 1 day PO for TCP, however, PT pins were more stable (p<.05) than all 3 NT pins at 2 weeks PO but only more stable (p<.05) than power inserted NP pins at 5 weeks PO. PT-SSP interfaces were more stable (p<.05) than PT-TCP at 1 day PO. At 5 weeks PO, NT-TCP, inserted with a hand chuck, were more stable (p<.05) than hand chuck inserted NT-SSP. TCP and SSP produced similar periosteal reactions at 2 weeks but TCP generated more reaction than SSP at 5 weeks. TCP and SSP produced similar magnitudes (p>.05) o…
