Cím:Our experience and early results with a complementary implant for the correction of major thoracic curves / Zoltán Csernátony, László Kiss, Sándor Manó, Zsolt Hunya
Megjegyzések:PURPOSE: In our article, we would like to introduce a new auxiliary implant called the CAB hook, for use in posterior approach scoliosis surgery. METHODS: Since 2007, we operated 42 patients with the CAB hook with an average preoperative Cobb angle of 59.3° (28°-92°). In three cases, the posterior approach was preceded by ventral release and Halo traction. In four cases, besides the CAB hooks, SCS hooks and pedicular screws, in three cases both CAB and SCS hooks, in nine cases CAB hooks with SCS pedicular screws, and in 23 cases, only CAB were used. The average follow-up time was 21.6 month (2-51). RESULTS: All the patients are satisfied with the results. No reoperation was needed due to the loss of correction, pain, implant failure, or infection. The average postoperative Cobb angle decreased to 24.7° (4°-60°). Based on this we calculated the Cincinnati Correction Index (CCI), which was 1.53 (0.7-4.8), which means that our correction exceeded the flexibility of the spine based on the lateral bending X-ray by 53 %. CONCLUSION: As with all new surgical techniques and implants after the short learning curve, we were able to improve the degree of correction and decrease the time of surgery. One of the advantages of the CAB hook is that besides a few implant-specific instruments, no special instrumentation is required for insertion, and image intensifier need not be used.

Cím:Biomechanical examination of the thoracic spine : the axial rotation moment and vertical loading capacity of the transverse process / Csernátony Z., Molnár Sz., Hunya Zs., Manó S., Kiss L.
Megjegyzések:Our objective was to examine the load-bearing capacity of the transverse processes of human cadaveric thoracic vertebrae to vertical loads and axial rotation moments (i.e., moment applied in the transverse plane). A secondary objective was to examine the effect of the attached rib stumps. We wanted to demonstrate that the transverse process is durable enough to support the CAB hook ? a complementary hook to the CD system ? and can handle the vertical load or axial rotation moment during correction of scoliosis. We used 107 thoracic vertebrae removed from 10 cadavers. They were prepared in vertebral pairs, and were fixed into a material testingapparatus. Superoinferior vertical loads and axial rotation moments were applied to the transverse process using the CAB hooks at a rate of 30 mm/min and 8.58/s respectively until it fractured. We recorded 142 measurements, 99 were for vertical load and 43 for axialrotation moment. The average ultimate vertical load was 338 (SD ? 128) N and the average ultimate axial rotation moment was 14.4 (SD ? 4.52) Nm. The ultimate axial rotation moment for specimens with rib stumps attached was significantly greater than for specimens without rib stumps 15.9 (SD ? 4.1) Nm versus 12.5 (SD ? 4.4) Nm. Our results showed that both the vertical and axial rotationloading capability of the transverse process are large enough to withstand significant correctional forces, without fracture, through the CAB hooks.
