Abstract
Background: In this prospective randomized clinical study, we report results of management of type C2 and C3 distal femur fractures by Ilizarov external fixator in comparison with double plating through separate medial and lateral approaches with a mean of 42.8 ± 6.84 weeks follow-up.
Patients and methods: In this study we managed 30 cases with highly comminuted distal femoral fractures AO classification type C2 or C3. Fifteen cases were surgically managed by Ilizarov technique and the other fifteen cases were surgically managed by double plating technique. We compare between both group as regard clinical, radiological results and rate of complications.
Results: while using Knee society score, the results are the following: In Ilizarov group: 7 cases (46.67%) are excellent, 4 cases (26.67%) are good, 3 cases (20.00%) had fair results while 1 case (6.67%) had poor results. In internal fixation group, 8 cases (53.33%) had excellent results, 3cases (20%) had good results, 2 cases (13.33%) had fair results while 2 cases (13.33%) had poor results.
Conclusion: In fixation of complex distal femur fracture, both Ilizarov and double plating methods had no significant difference in clinical outcome by knee society score and in rate of complications. Ilizarov allow earlier weight bearing and less blood loss while double plating gives better ROM of knee joint and rapid radiological healing.
