Operative management of displaced acetabular fractures: an institutional experience with a midterm follow-up.

BACKGROUND: Operative management is considered to be the treatment of choice in acetabular fractures as this is the unique way of achieving precise anatomical reduction, stable internal fixation, and early mobilization of joint. With this background in mind we undertook a prospective study with an aim to assess the outcome of surgery in displaced acetabular fractures at our general orthopedic centre as a first experience. MATERIAL AND METHODS: This study was conducted on 59 patients (45 Males, 14 Females ) with mean age of 38.35 years (range 18-60 years) with displaced acetabular fractures who were admitted consecutively at our centre from May 2008 through November 2011. Nine patients (7 Male, 2 Female) were lost during follow up. The average follow up was 3.5 years (range 2-5 years). Prophylaxis for deep venous thrombosis and heterotopic ossification was used routinely in all patients. RESULTS: Clinical evaluation was based on modified Merle-d'Aubigne and Postel scoring system. Radiological evaluation was done according to criteria developed by Matta. It was graded as excellent in 16% hips, good in 54% hips, fair in 20% hips and poor in 10% hips. Good to excellent results were achieved in 42 cases (70%). The complications included were implant backout, postoperative dislocation, iatrogenic nerve palsy, superficial wound infection, intraoperative bleeding and osteoarthritis. There is a positive relationship between quality of reduction and functional outcome. In our series, radiographic congruity (75%) correlated well with the function (70%). CONCLUSIONS: 1. We conclude that operative treatment is a safe and effective method of managing displaced acetabular fractures even in general orthopedic centres. 2. Time spent on a thorough study of the radiographs/CT scan for a proper preoperative plan is worthwhile and helps to outline an appropriate surgical approach and avoid complications.
