[Surgical treatment of acetabular type C1 acetabular fracture by posteroproximal-posteroanterior sequential reduction and internal fixation].

ABSTRACT

OBJECTIVE: To investigate the operative reduction techniques and clinical results of surgical treatment of type C1 (AO/ASIF) acetabular fracture by posteroproximal-posteroanterior sequential reduction and internal fixation. METHODS: From August 2004 to January 2012, 13 patients with type C1 (AO/ASIF) acetabular fracture were treated by posteroproximal-posteroanterior sequential reduction and internal fixation. Of them, 8 cases were male and 5 cases were female with an average age of 42 years years old (ranged, 18 to 64). Pelvis 3-dimentional CT reconstruction were used to confirmed the classification of fracture, and the operation were performed during from 5 to 20 days with an average of 9.5 days. Operation time, blood loss, complications and reduction were recorded and evaluated. The function of hip joint were accessed at the final follow-up. RESULTS: The operation time ranged from 190 to 290 min with an average of 240 min. The mean blood loss was 1 800 ml (ranged, 1 300 to 3 000 ml). One case had superficial infection and healed after 3 weeks. According to Matta reduction criteria, 8 cases obtained anatomical reduction, 4 cases got satisfied results and 1 cases got unsatisfied results. Eleven cases were followed up with an average of (24.0 +/- 8.0) months, and 2 cases were lost to follow-up. According to revised Mede d'Aubingne and Postel evaluation system, 7 cases got excellent results, 2 good, 1 moderate and 1 poor. CONCLUSION: Posteroproximal-posteroanterior sequential reduction and internal fixation for the treatment of type C1 (AO/ASIF) acetabular fracture can achieve satisfied surgical proces and operation quality.
