In the current study of short-term results of revision total knee arthroplasty for treatment ofsupracondylar fracture of the femur after total knee with osteoporosis, the component haveshown to remain stable in weight bearing conditions and functioned well. Fracture healing andgood clinical outcome, evaluated according to the JOA score, were achieved in all cases.Longer-term outcome should be the subject of further investigation. Conclusion. The revisionTKA was a successful method for treatment of the supracondylar fracture after TKA.Saturday, October 9, 2010, 10:20-11:05Session A19: Miscellaneous ArthroplastyPercutaneous Axial Lumbar Interbody Fusion (AxiaLIF): Technical andClinical Topics of a New Minimally Invasive Lower Spine Fusion Way.*Lorenzo Marzona - Massa General Hospital - Tuscany AUSL1 - Massa, ItalyAlberto Sancin - - Massa,*Email: lorenzomarz@tiscali.itNowadays many new minimally invasive techniques are experienced to perform lower lumbarinterbody fusion in attempt to decrease the complications related to open anterior approach.AxiaLIF (axial lumbar interbody fusion) system is a percutaneous transacral approach thatexploits the virtual presacral retroperitoneal space to perform annulus-sparing discectomy andinterbody instrumented fusion of lower lumbar disc spaces. Additioning posterior percutaneousinstrumentation, a robust axial construct is placed which restores disc height, sagittal balanceand lordosis with minimal muscle dissection, blood loss and postoperative pain.Via fluoroscopically-guided approach, AxiaLIF procedure creates a presacral retroperitonealcorridor in the midline through a paracoccigeal skin incision of 2-3 cm. This space is void ofneuro-vascular major elements. A safe working cannula is put in and docked in the S1-S1 entrylevel and a transacral channel is realized gaining the central space of the disc. A 360° annulussparingradial discectomy is performed with special cutters even in case of collapsed disc spaceand the bone graft is inserted. The following screwing of AxiaLIF rod restores disc height viadistraction if necessary, decompresses the neural foramen indirectly and undertakesinstantaneous rigid fixation of adjacent vertebral bodies. Using the same incision point andtrajectory through the presacral space as AxiaLIF, it is possible to realized a similar procedureL4-S1 vertebral fusions called AxiaLIF 2L.Between february 2009 and may 2010 25 patients (16F:9M) affected by degenerative discdisease (17) and grade 1 or 2 spondylolisthesis (8) were included in this study. Evaluatedoutcomes were the amount of bleeding, the presence of presacral hematoma, the functionalrecovery time, the surgery time rate, the x-ray time rate, the complication rate (infection, pelvicvisceral injury, postoperative pain).21 of 25 patients underwent AxiaLIF L5-S1 procedures, 4 of these with a stand alone implantand 17 followed by posterior instrumentation. In the remaining 4 patients, a AxiaLIF 2L L4-S1procedures is performed. 4 of 25 patients had a perioperative suction drenage. Mean operativetime for L5-S1 AxiaLIF procedure was 49 minutes. A 2 nd p.o.d. CT pelvic scan of undrainedand drained groups showed a mean presacral hematoma of 45 cc and 17 cc respectively reducedfile:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
