Abstract
Korat Dynamic External Fixator System (KDEFS) has been used since 2003 for definite treatment of opened fracture which had the good result. Then the authors developed KDEFS accessories for treatment of many complications from opened fracture in one system. Objective: To evaluate the result of KDEFS in 6 functions 1. Bone transportation 2. Bone lengthening 3. Infected nonunion treatment 4. Bone gap closure 5. Hybrid external fixator and 6. Correction of malunion. Patients & Methods: Preliminary study in patients with 6 conditions in Maharat Nakhon Ratchasima Hospital during May 2006 – April 2007. Results: 1. Bone transportations were dome in 3 patient with segmental bone loss. The transportation length was 4.4- 6.1 cm. (average 5.1 cm.). The union time was 22-28 weeks (average 24 weeks) 2. Bone lengthening was performed in one patient. The lengthening length was 3.5 cm. in 8 weeks and the union time was 20 weeks. 3. Infected nonunion in 2 tibias and 2 femurs were treated. The union time of tibias were 12, 15 weeks and femurs were 18, 20 weeks.4. Bone gap of 19 patients were successfully closed intraoperatively. 5. Hybrid external fixators were applied in 1 tibial plateau fracture and 1 tibial plafond fracture. The union time were 14 and 16 weeks. 6. Correction of tibial malunion was done with successful correction in 3 weeks and the union time was 12 weeks. Conclusion: KDEFS was the new generation external fixator that has multi-function propose.
