Treatment of grade IIIB opens tibial fracture by Ilizarov hybrid external fixator.

OBJECTIVE We evaluated the results of patients who were treated with Ilizarov hybrid external fixator for type IIIB open tibial fractures. MATERIALS AND METHODS 35 Gustilo grade IIIB tibial fractures of age between 18 to 42 years (22 male and 13 female) in which 12 distal fourth tibia (D/4) of C1.1 (6), C1.3 (6), 12 upper fourth Tibia (U/4) of A2 (8) and A3 (4) according to AO classification and 11 Tibial plateau fractures of Schatzker type VI (5) , V(5), IV(1) . All tibial plateau, proximal fourth fractures and lower fourth fractures of tibia and fibula (Reversed Hybrid), treated with Ilizarov hybrid fixator using two Ilizarov 5/8 rings and AO External fixator were followed up to 12-52 months. RESULTS D/4 fractures were united at 31.16678.3046 wks, U/4 at 24.005.2915 and Tibial plateau at 15.5454.160 weeks (p-0.00). ROM in tibial plateau type IV 130 degrees +/- 00, type V 124 degrees +/- 8.94 degrees, type VI 125 degrees +/- 7.0711 degrees, D/4 of type C1.1 (50 degrees +/- 0.00), type C1.3 (43 degrees +/- 5.7755) whereas full ROM in U/4 fractures. Pin tract infection occurred in 21% of cases. Pain on walking in 20% of cases of type VI tibial plateau fractures and 80% of cases of type IV and V. Problem free in rest of parameter of function of VI and 100% problem in IV and V. Pain at rest observed in 20% of cases in type V. In 66.67% U/4 fractures had pain on walking but no other functions were compromised. In 33% D/4 fractures of C1.1 type had pain on walking only and had 1cm of shortening. CONCLUSION On the basis of our experience, we suggest adopting this method for functional limb salvage after extensive complex high-energy injuries. This fixator is safe and versatile, effective in providing stability and allowing early rehabilitation, although the indications for its use are very relatively specific.
