Eleven newborn babies of normal weights sustained falls onto a hard surface in hospital. The one baby who fell from >1 m sustained clinical and radiological trauma and encephalopathy, with a skull fracture and cerebral contusion. No other baby demonstrated neurological signs despite the presence of parietal skull fractures in four of six who were x rayed; only two babies had scalp swelling. The findings suggest that parietal fractures can result from very low-level falls, and scalp swelling is a poor marker for underlying fracture.

Statistics from

The conditions under which very young infants can sustain skull fractures can be contentious, but are clearly important in determining whether an injury might be consistent with the history given. Studies of linear skull fractures and external evidence of skull injury have mostly focused on falls of ≥3 feet,1 2 so there is little information on the outcomes of lower-level falls. In the context of the accident and emergency department, the prevarication and false histories that are part of the presentation of child abuse create difficulties for clinicians and researchers alike.

Therefore, we believed it would be useful to present our experience of injuries sustained from falls in newborn babies in the postnatal ward where the fall occurred under verifiable conditions, or was witnessed by someone other than the mother; there was information about the physical environment; immediate medical assessment was available; and many of the falls were from heights as low as 0.5 m.


We used our adverse event register, cross-checked with the codings for all trauma in newborn babies from the Hospital Episode Statistics, to identify caseswhere babies fell accidentally to the floor in our maternity unit during 5 years from January 1999 to December 2003. The records for each child were examined; details of the height to impact, nature of the surface struck, clinical symptoms, and the results of any imaging were identified for each child.


The details of the babies are given in table 1. Eleven babies were identified, seven girls and four boys, all born at term. Birth weights ranged from 2.1 kg to 3.8 kg. Of the 11, seven were totally breast fed, three artificially fed and one mixed fed. Seven of the falls occurred at night, between the hours of 20:00 and 08:00. Four babies dropped to the floor when their mothers fell asleep following breast feeding.

Relevant clinical details of the 11 babies

The estimated distance to impact in most babies was ≤1 m. One baby fell about 1.2 m. The surface impacted upon in all falls consisted of vinyl tiles laid upon concrete with an intervening solid screed.

No clinical findings were identified in eight of the 11 babies. Of the three with clinical findings, one had a bruise over the temporal area, one had a swelling over the parietal area, and one had signs of traumatic encephalopathy.

All imaging was at the discretion of the attending physicians. Six of the 11 babies had skull x rays, one had a CT scan (but no skull x ray), and two had an ultrasound scan. Of the six with x rays, five had no scalp swelling, but three of these five had a solitary linear parietal skull fracture. Three of the 11 babies had localised scalp swelling, of which two were imaged and each of these had a single linear parietal fracture. The baby who fell 1.2 m had a fronto-parietal contusion beneath the fracture, and had a transiently decreased level of consciousness consistent with a mild traumatic encephalopathy; this baby was born by normal vaginal delivery.


Our observations demonstrate that low-height falls of <1 m can cause a linear skull fracture, and such skull fracture is not necessarily accompanied by a boggy swelling in the overlying scalp. However, not all babies were radiographed so we cannot make any estimate of the rate of fracture among babies who fall.

All the fractures, including that caused by the highest fall, were linear and confined to the parietes. Even the baby falling further, and sustaining brain contusion, had a linear fracture, not a more complex one. Although this finding supports the contention that complex, stellate or occipital fractures do not arise from simple domestic falls3 we cannot rule out the possibility that other kinds of fracture could result from falls such as we have seen.

In spite of the fact that hospital floors are particularly hard and unyielding, we found that symptoms suggestive of underlying brain injury (decreased consciousness, feeding problems, irritability, seizures or apnoea) were not found in 10 of 11 babies, even when fractures were found to have occurred. Existing biomechanical evidence suggests that there is little difference in the effects of falls onto a hard floor or a carpeted domestic floor.4 We conclude that even very lowlevel falls may produce linear skull fractures, but that such fractures may occur without the scalp swelling traditionally considered suggestive of a fracture.
