Comparison of three methods of Müller type C2 and C3 distal femoral fracture repair.

BACKGROUND

We compared the outcomes of three fixation techniques for Müller type C2 and C3 distal femoral fractures.

METHODS

We retrospectively analyzed patients undergoing internal fixation for Müller type C2 and C3 distal femoral fractures via locking plate (Group A), lateral locking condylar plate and medial contoured reconstruction plate (Group B), and lateral locking condylar plate and anterior reconstruction plate (Group C). Knee joint functional recovery and functional outcomes were evaluated 12 months postoperatively.

RESULTS

Patients included 34 men and 24 women aged 25 to 74 years (mean, 50.3 ± 10.73 years). Operating times were longest in Group B and similar in Groups A and C. Bleeding volume in Group A was smaller than in Group B and similar to that of Group C. Functional outcomes were excellent in 18 (31%) fractures, good in 24 (41%), moderate in 11 (19%), and poor in 5 (9%). Good-to-excellent results were achieved in 56%, 82%, and 83% of patients (Groups A, B, and C, respectively). Groups B and C's outcomes were superior to Group A's outcomes. No significant difference in postoperative complications between the groups existed.

CONCLUSION

Lateral locking condylar and anterior reconstruction plating was useful for complex type C distal femoral fractures.
