Retrograde drill usage, illustration 插畫檔

Illustration of the stepwise procedure of the reverse reaming technique for bone tunnel preparation during anterior cruciate ligament reconstruction. The sequence demonstrates the establishment of the initial pilot channel using a guide drill, the secure embedding of the drill sleeve tip, the flipping of the cutting blade into the operative position, the reverse cutting of the porous cancellous bone by the reamer and the final enlargement of the tunnel to the predetermined diameter. This technique is designed to replace traditional hollow drills and minimize bone trauma
