title: Computed tomography grade of splenic injury is predictive of the time required for radiographic healing.
abstract: It is largely unknown when a child who has suffered a splenic laceration can return to full unrestricted activity. The purpose of this prospective study is to establish whether the grade of splenic injury is predictive of the length of time required for radiographic healing, and to determine whether there are any adverse long-term sequelae after resumption of unlimited activity. Sixty-nine patients underwent successful nonoperative management (NOM) of computed tomography (CT)-documented splenic injury over a 4-year period. Fifty-eight patients completed follow-up. Mean age was 9.8 years (range, 1 to 17) and mean injury severity score (ISS) was 14.4 (range, 4 to 38). Mechanisms of injury were motor vehicle accident (n = 11), motor vehicle pedestrian (n = 5), falls (n = 13), bike crashes (n = 12), sports (n = 8), all-terrain vehicle (n = 4), and horse (n = 5). The CT-documented injury was identified by discharge ultrasound scan (US) in all cases. There were no long-term complications. Mean time to US healing in grade I (n = 9), II (n = 26), III (n = 19), IV (n = 4) injuries was 3.1, 8.2, 12.1, and 20.7 weeks, respectively. P values were significant (P < .01) in all cases when compared with the next lower injury grade. The time to radiographic healing is directly proportional to the severity of the splenic injury. There was excellent correlation between the initial CT scan and identification of the injury on the discharge US. No long-term complications leg, delayed splenic rupture, splenic pseudocyst) were seen in this study. Pediatric patients who have suffered splenic injury can safely return to full unrestricted activity when the US documents healing.
