COMFORTABLE AND SECURE INSTALLATION FOR THE COMBINED KOCHER-LANGUENBECK AND ILIOINGUINAL SURGICAL TREATMENT OF COMPLEX ACETABULAR FRACTURES: TECHNICAL ASPECTS AND RESULTS OF 53 SURGICAL CASES

Abstract

Background: The Rangeuil orthopaedics surgical team has developed a special installation using a rigid corset for the combine Kocher Languenbeck and ilioinguinal surgical treatment of complex acetabular fractures. The purpose of this study was to retrospectively evaluate the results of 53 complex acetabular fractures treated by open reduction and internal fixation with a combined double approach facilitated by this particular operative installation.

Methods: A retrospective review of the cases was performed. The functional outcome, operative times, blood loss were recorded. Pre-operative, post-operative and last follow-up radiographs were assessed for fracture classification and adequacy of reduction. The development of heterotopic ossification, the presence of infection, avascular necrosis and post-traumatic osteoarthritis were also noted.

Results: The mean follow-up was 5.2 years. The clinical outcome at the time of final follow-up was graded as excellent in 16 patients, good in 22, fair in 7 and poor in 8 The reduction of the fracture, as determined with plain radiography, was graded as anatomic in 32 patients, unperfect in 15 and unsatisfactory in 6. Bony union was achieved in all cases. 6 patients had Brooker 3 or 4 heterotopic ossifications. 9 patients developed osteoarthritis. 4 patients developed avascular necrosis. An arthroplasty was necessary for 10 patients. 3 patients had a delayed wound infection.

Conclusions: The combined simultaneous approach remains a reliable surgical solution in selected complex acetabular fractures. The installation using the corset we developed considerably simplifies the operation and access to the operated site.
