Osseointegrated Transcutaneous Device for Amputees: A Pilot Large Animal Model

Figure 1

(a) During the first procedure, the spindle and anchor plug are implanted. A cap is placed over the spindle and the soft tissues are closed to allow for provisional healing. (b) The cap is removed at the second surgery and the taper fit transcutaneous adapter is applied. (c) A cross section of the implant demonstrating the compression mechanism. Compression of the spindle against the bone is generated by tightening of the anchor plug locking nut against the Belleville washers. The anchor plug is secured proximally by cross pins (not shown). A silicone gasket fits within the distal end of the spindle to deter bacterial migration proximally into the canal. The taper fit transcutaneous adapter is attached over the distal aspect of the spindle.
