ABSTRACT
Objective To evaluate the modified Physical and Operative Severity Score for the Enumera-tion of Mortality and Morbidity (POSSUM) in predicting the postoperative morbidity in patients with fractures of the pelvis and acetabulum. Methods The clinical data of 94 patients with pelvic and acetabular fractures were retrospectively analyzed. Their postoperative prognosis during hospital stay was evaluated with the POSSUM scoring system modified according to the features of orthopedics and pelvic and acetabular fractures. The peritoneum in-fection in the severity index of operation was replaced by operative approach, the several operations at one time by operative duration, and the cancer by the associated injury. The size and type of operation were made into 4 grades with corresponding orthopedic scores. The scores were compared between the complication group and the non-complication group. The receiver operator characteristic (ROC) curve was drawn to describe the coincidence degree, define the cut points, and evaluate its predicting capability. Results The mean preoperative physi-ological score (PS) and operative severity score (OS) in the complication group (38 cases) were significantly higher than those in the noncomptication (56 cases) (17.26 ± 2.84 vs 16.04 ± 2.77; 19.50 ± 5. 14 vs 13.00 ±3.81 ) ( P < 0.05) . In the modified POSSUM, the area under ROC curve was 0. 856, the cut point 43%, sen-sitivity 73.68%, specificity 80. 36%, and coincidence degree 77.66%. Conclusions Since the modified POSSUM scoring system has a high capability of predicting postoperative morbidity for fractures of the pelvis and acetabulum, it can be helpful for surgeons to lower operative risks and ensure safety in operation. When the score is higher than the cut point, the risk is too great for an operation. Therefore, the fracture should be treated non-operatively or mini-invasively until the score is lower than the cut point.
