Abstract
OBJECTIVES: To propose the regional injury classification of open pelvic fracture and summarize the characteristics of its treatment. METHODS: Clinical data for 67 open pelvic fractures treated from January 2001 to December 2017 were retrospectively analyzed. There were 48 male and 19 female patients. The patients were aged from 12 to 68 years old, and their pelvic fractures were categorized according to Tile classification (type A: 23 cases; type B: 19 cases; type C: 25 cases). Main injury distribution: pubic perineum, 29 cases; ilioinguinal, 20 cases; and sacroiliac, 7 cases. There were 5 cases of ilioinguinal-perineum and 6 cases of sacroiliac-perineum injury. Based on the region of the injury, the mortality and combined injury of each group were observed. The relationship between regional injury groups and death was examined. RESULTS: Following active treatment, 28 patients died. The mortality rate was 41.8% (28/67), with 39 patients surviving. The average follow-up time was 6 months (3 months to 1 year after discharge). Majeed pelvic fracture score: the score was excellent in 12 cases, good in 14 cases, fair in 9 cases, and poor in 4 cases; there was an excellent and good rate of 66.7%. Open pelvic fracture regional injury classification includes: the perineal type (type I); the ilioinguinal type (type II); the sacroiliac type (type III); and the composite type (type IV). All types were independent of each other, and the mortality of open pelvic fractures was positively correlated with this classification, with a correlation coefficient of 0.620 (P = 0.001 < 0.05; the difference was statistically significant). In this study, cystourethral injury, anorectal injury, and infection were the main combined injuries of type I. The type II and III injuries were mainly iliac vascular injuries. The main combined injuries of type IV were infection, injury of ilium vessels and its branches. There was a statistical difference among the combined injuries of each subtype (P = 0.001 < 0.05). CONCLUSIONS: The criteria for regional classification were clear, the mortality of the four subtypes increased gradually, and the incidence of combined injury of each subtype varied. Each subtype had different therapeutic characteristics.
