Abstract
BACKGROUND: The aim of this study was to explore the surgical treatment of transverse with or without posterior wall fractures of the acetabulum.
MATERIAL AND METHODS: We surgically treated 21 consecutive cases of pure transverse (7 cases) and with posterior wall (14 cases) fractures of the acetabulum. The anterior column fractures were firstly reduced, temporarily fixed through a modified Smith-Petersen small incision, and finally fixed after the fixation of the posterior column and wall fractures, which were reduced and fixed through a Kocher-Langenbeck approach. The operative time, intra-operative blood loss, quality of reduction (Matta criteria), perioperative complications, osseous union, subsequent complications, and hip function evaluation were recorded.
RESULTS: The mean operative time was 198.1 min and the mean intra-operative blood loss was 938.1 ml. Anatomic reduction of the anterior column was obtained in 20 cases and was imperfect in 1 case. All posterior column and wall fractures were anatomically reduced. We followed up 18 cases for a mean duration of 16.3 (8–30) months. All the fractures achieved osseous union. The mean Harris score was 85.1 points, with an excellent result in 7 cases, good in 8, fair in 2, and poor in 1. According to modified Merle d’ Aubigne and Postel score system, the results were excellent in 2 cases, good in 15, and poor in 1. Avascular necrosis of the femoral head occurred in 1 case, heterotopic ossification in 3 cases, and numbness of the anterolateral thigh in 6 cases.
CONCLUSIONS: For transverse with or without posterior wall fractures of the acetabulum, reduction and fixation of anterior and posterior column should be done in sequence, and a modified Smith-Petersen small incision might be a good choice in reduction and fixation of the anterior column because it possesses advantages of direct visualization and minimal invasion.
