Objective: To determine the occurrence of bruising near the site of fracture in a group of children with inflicted fractures., Design: Case series., Setting: Two children's hospitals., Participants: Suspected child abuse victims with fractures., Main Outcome Measure: The presence of bruising and fracture in a single body region or appendage., Results: The study included 192 children with inflicted fractures. No bruising was found in 111 (57.8%) of the study participants. Forty patients (20.8%) had bruising near the site of at least 1 fracture. Of these, bruising or subgaleal hematoma near the site of a skull fracture was seen most often, in 43.3% of patients. Bruising in association with extremity fractures was seen much less commonly, ranging from 3.8% (n = 2) of children with tibia fracture to 16.7% (n = 1) of children with fibula fracture. Rib fractures also were associated uncommonly with bruising. When skull fractures are excluded, 45 (8.1%) of 555 fractures had bruising near the fracture site, in 13 (6.8%) patients., Conclusions: In children with inflicted skeletal trauma, the fractured bones that most frequently have associated bruising are the skull bones. The presence of bruising near the fracture site is uncommon in extremity or rib fractures.

Background: Scientific and courtroom debate exists regarding the timing of onset of symptoms and the mechanism of injury in infants and children with inflicted traumatic brain injury (ITBI)., Objectives: To determine the time interval between ITBI and the onset of symptoms and to explore the mechanism of ITBI., Design, Setting, and Patients: Retrospective review of all cases of pediatric ITBI admitted between January 1, 1981, and July 31, 2001, to a large academic medical center and cases admitted to 2 additional academic institutions between January 1, 1996, and August 31, 2000, and January 1, 2001, and July 31, 2001, comparing 81 cases of ITBI in which perpetrators admitted to abuse with 90 cases in which no abuse admission was made. The patients with perpetrator admissions to ITBI consisted of 53 boys (65%) and 28 girls (35%). Their ages ranged from 2 weeks to 52 months., Main Outcome Measures: Characteristics associated with perpetrator admissions to ITBI in children., Results: Shaking was the most common mechanism of injury among all cases with perpetrator admissions: 55 (68%) of the 81 perpetrators admitted to shaking the children. Impact was not described in 44 (54%) of the 81 cases. In cases in which only impact was described, 60% (12/20) of the children showed skull or scalp injury, compared with 12% (4/32) with skull or scalp injury in the shake only group. In 52 (91%) of 57 cases in which the time to the onset of symptoms was described, symptoms appeared immediately after the abuse. In 5 cases (9%), the timing of symptoms was less clear, but they occurred within 24 hours. None of the children were described as behaving normally after the event., Conclusions: The symptoms of inflicted head injury in children are immediate. Most perpetrators admitted to shaking without impact. These data, combined with the relative lack of skull and scalp injury, suggest that shaking alone can produce the symptoms seen in children with ITBI.
