Further, the bioabsorbable interference screw front is obtuse, and the bioabsorbable interference screw head 1mm or less is full thread.
Further, half slot type elliptical aperture described in every group includes 2 half slot type elliptical apertures.
Further, the adjacent two half slot type elliptical apertures are at a distance of 15-20mm.
Further, half slot type elliptical aperture described in adjacent two groups is at a distance of 25-35mm.
Further, half slot type elliptical aperture described in every group includes 3 half slot type elliptical apertures.
Further, the adjacent two half slot type elliptical apertures are at a distance of 18-25mm.
Further, half slot type elliptical aperture described in adjacent two groups is at a distance of 30-50mm.
Further, the width of the fixation steel plate is 12-18mm.
The beneficial effects of the utility model：By the way that bioabsorbable interference screw is arranged, in union, be screwed into the spiral shell of human body
Nail is absorbed substantially, and annular cutting edge is provided on fixation steel plate, when steel plate to be removed directly in annular cutting edge
Cut-out screw catches on half slot type hole two by tool, fixation steel plate is ticked, and reduces during taking out steel plate after fracture recovering
Wound, reduce pain.
