An orthopedic bone bridge, suitable for internally fixating and stabilizing fractured bones. The bone bridge includes: first and second bone plates for attachment to bone fragments by bone screws or the like on opposite sides of a bone fracture, a pair elongate parallel hollow legs on which the plates are mounted and the second plate is slidably engaged and is moveable with respect to the first plate, and an elastic cable or microcable attached to the first plate and extending down through the legs and around said second plate. The elastic cable is configured to provide a controlled tensile force between the plates when they are pulled into a longitudinally spaced apart position with the bone bridge then applying a correspondingly compressive force onto the bone fracture when the plates are secured to bone fragments on opposite sides of a bone fracture.

The invention discloses a method for preparing a hydroxyapatite coat/surface activated titanium-based composite coat. The method comprises the following steps: 1) performing surface biological activation treatment on titanium or titanium alloy serving as a base material to form a titanium gel layer, and cleaning and drying the titanium base material; 2) preserving the heat of the titanium base material at a high temperature to form an oxidized titanium film; 3) synthesizing hydroxyapatite by using a wet method, and sintering, crushing and sieving the hydroxyapatite to obtain powder; 4) preparing a thin hydroxyapatite coat on the oxidized titanium film by using plasma spraying technology; and 5) putting the hydroxyapatite coat product in a container, and drying the treated product by using water vapor to obtain the hydroxyapatite coat/surface activated titanium-based composite coat. The process is simple; when an obtained coat compound implanted material is implanted to the human body, the material plays a role in bone bridge connection of the hydroxyapatite at the early stage, provides rich calcium and phosphorus elements for bone growth, accelerates the growth of a new bone, and shortens an operation healing stage; and when the hydroxyapatite coat is basically degraded, the bone texture and the metal surface form a direct chemical bond combination.
