“Presented with Dad (Mum at home waiting on furniture people). Parents concerned about ‘bump’ that has appeared on right side of forehead. Dad noticed it when picking M up from her morning sleep. Not aware of any trauma to head …. M has been sleeping, eating and drinking as normal ….M crying +++ Dad says only since being in medical centre …. Right side of forehead does look larger compared to left but no obvious swelling or bruising …On holding the left side of M’s chest, feels crackly and seems uncomfortable. Dad explained M has had chest infections in the past …. Dad wanted to be sure swelling to head was nothing to worry about.” 23). The father accepts that he did not tell the truth to the nurse. He said in evidence that he was “absolutely terrified” and did not want social services involved with the family again. 24). The nurse referred M to the GP whose note reads as follows: “Dad brought her up because noticed lump right forehead and had no idea how it came there. M recently well and fed/behaved normally after he noticed it. Seen by practice nurse who observed unusual crackling feeling in chest when held her. Dad reported this has been there since birth …. Palpable (not audible) ‘crackling’ left side chest on inspiration, never felt anything like it. Also observed [over] 1 cm round green bruise to right of thoracic spine but no other bruises, moving and responding normally.” 25). She did not refer to any swelling on the head. 26). M was then referred to the local hospital, and she was taken there by both parents. She was seen first at 3 pm by a junior doctor who noted the presenting complaint as (1) a lump on the right side of the forehead (2) ‘crepitus’ on the left side of the chest noticed by the GP and (3) a bruise on the left side thoracic spine. In his note of his examination, the junior doctor described M as “alert, happy, active”
“M appeared well alert and interacting normally with her parents. She appeared well nourished and well cared for…on her forehead there was a small 1 cm faint bruise on the upper right forehead which is not incompatible with the explanation of banging her head on the cot side. It was probably a few days old. More significantly, on her lower back, there was a 1 cm diameter small purple green bruise, about 1 cm lateral to the spine on the left, overlaying the seventh rib. Adjacent to this I could feel an area of crepitus a crunching sensation coming from the underlying rib bone, which did not appear to be particularly painful.’ 28). As a result of this finding, the paediatrician asked for a chest x-ray. As reported by other radiologists, this showed a definite fracture of the left eighth rib posteriorly in a place which the paediatrician described as ‘consistent with the crepitus’. There was also some suspicion of recent injury to the left, ninth and tenth ribs immediately below this. Suspecting that these injuries may have sustained non-accidentally, the doctors informed social services. 29). When the paediatrician confronted the parents with the news about the rib fracture, they were very surprised and distressed. They did not provide any explanation at that stage. At that point, the father left the hospital ostensibly to collect L. In the event, however, he did not immediately return with the boy. In his statement, he explains his actions as follows: 30). “I went home with the intention of dropping L with the neighbour and to bring some overnight things. On the way home I came to my senses and realised that by not admitting what had happened I wasn’t protecting anyone. I sorted L out with the neighbour and went back to the hospital where I told T what had happened”. 31). It is the mother’s evidence that on receiving this news she slapped the father’s face. She said in evidence before me that she had done this because the father had lied, had not come clean about dropping the baby and left her thinking that she had done something wrong. The father does not recall the slap. 32). When the social worker arrived, the father told her what had happened on the previous day. A note taken by a doctor at the time recalls the father saying that M ‘fell out of arms and hit side on coffee table and fell to floor. He was stooped over and the coffee table was low so she did not fall from high. She cried immediately but settled soon afterwards.’. 33). On 4th August the father was interviewed by the police. He set out his account of the incident on 2nd August. According to one of the hospital nurses, the mother told her later that evening that she did not want the father to come back to the ward “in case he says something wrong”
“chest: small dark purple-green bruise 1 cm diameter left lower chest, I cm lateral to spine. Close to this bruise, I can palpate definite crepitus in a rib, ?7th rib, not obviously painful”
“without doing specific experiments in human children it is very difficult to be certain. Animal studies suggest that the healing has usually stabilised the bone within about one week and up to 14 days after the fracture occurred.” 63). Counsel for the parents rely on the evidence of Dr. Chapman on the timing of crepitus in support of their submission that the 8th rib facture could have occurred on 2nd August. They invite the court to prefer the evidence of Dr. Chapman on this point to that of Prof Bishop, pointing out that the studies to which the latter referred were carried out on animals, that Prof Bishop said that he had not felt any crepitus for 5 years, and that he deferred to the radiologists as to the timing of the rib fractures. Frank Feehan QC on behalf of father submits that radiology has elements of the “art” as well as the science and that radiologists see different things in the same scan and it is a matter of interpretation, which is not certain. He adds that what he characterises as the initial slightly dogmatic approach of the radiologists is ameliorated by their acceptance that these matters must be taken into account. It is submitted that their “certainty” as to the age of this fracture is nothing of the sort. 64). I accept that there is an element of “art” in the interpretation of radiographs. They are, after all, artefacts. The court has experience in other cases of the evidence of radiologists being contradicted by pathologists following a physical examination of a bone in a post mortem examination. I also accept that the court must consider all the evidence on this point, including the clinical presentation of the child. Nonetheless, I found the evidence of Dr. Chapman and Dr. Halliday as to the dating of the 8th rib facture to be compelling. I reject the suggestion made by Frank Feehan QC and Alexa Storey-Rea in closing submissions that there was an element of dogmatism in their evidence on this point. Their combined experience of interpreting x-rays of rib fractures leads them to advise the court that, at the outside, the fracture of M’s 8th rib occurred at the latest on 1st August and more probably a few days earlier. I do not consider that the evidence as to crepitus undermined their opinion on this point, and in any event I found Prof Bishop’s more detailed explanation as to crepitus more persuasive than that given by Dr. Chapman. Before reaching a final conclusion as to timing of the rib fractures, however, I must of course consider the medical evidence in the light of the other evidence to which I shall turn later. 65). Both radiologists stated that rib fractures were commonly caused by the application of compressive forces rather than direct impact. They both thought that the account given by the mother of the incident in the bath was a possible explanation for the earlier fractures. Dr. Halliday said: “it is within date and if the child were grabbed and compressed around the waist it would be possible that would account for those two fractures. It would be unusual but it would be possible.” (2). Skull fractures (a) The initial consensus and conundrum 66). It was the evidence and analysis of the head injuries presented to Judge Marshall that created what she described as “the conundrum” in this case. That evidence and analysis is set out at length in the judgments of both Judge Marshall at first instance and Munby LJ in the CA. In short, the consensus of expert opinion at that stage can be summarised as follows. 67). First, the CT scan and skeletal survey demonstrated that M had complex fractures of the skull. An infant’s skull comprises, in simple terms, plates of bones – the frontal bones, two parietal bones on each side, and the occipital bone at the back – joined together by fibrous areas known as sutures – the sagittal suture running along the top of the head from front to back separating the two parietal bones, the coronal suture running across the front of the head separating the frontal bone from the two parietal bones, and the lambdoid suture – so called because it is shaped like the Greek letter lambda – which runs across the back of the head between the two parietal bones and the occipital bone. In his first report, Dr. Chapman summarised the fractures (illustrated by a 3D representation of the CT scans) as complex fractures of both parietal bones and the occipital bone and particularised them as follows: (1)on the right side, a long horizontal fracture of the parietal bone extending from the coronal suture to the lambdoid suture; (2)further fracture lines extending upwards from the first fracture, the larger one from roughly the middle of the first fracture to the sagittal suture, and a smaller one posteriorly; (3)a further fracture extending from the posterior end of the sagittal suture towards the middle of the parietal bone, meeting the smaller vertical fracture; (4)on the left side, an even more complex fracture of the parietal bone with limbs that extend to all the sutures on that side of the head; (5)a complex fracture of the left side of the occipital bone; (6)mild widening of the posterior end of the sagittal suture (probably reflecting trauma to the suture itself). 68). In addition, Dr. Chapman observed “widespread bilateral scalp swelling”, most prominently on the right frontal region at the top of the skull. He also observed what he described as two or three short lines extending from the sagittal suture into each parietal bone which could represent further fractures. Alternatively, he thought they might represent normal variants know as “fissures”, fibrous areas where the bone is not quite as well formed. Subsequently in oral evidence before me he described how the skull bones form in a radial or “star” pattern which sometimes results in areas between the “rays” of the star that are not fully formed in the baby’s skull, remnants of the incomplete ossification of the bone. It is quite common to see fissures going out from the main sutures into the skull in a young baby, although they become less common as the child grows and the bone becomes completely ossified. 69). Both Dr. Halliday and Mr. Richards agreed with Dr. Chapman’s analysis of the fractures. The word used by Mr. Richards to describe these fractures, with which no other expert disagreed, was “spectacular”
“occasionally in clinical practice patients present following high force injuries where significant brain injury could be expected and are found to have extensive fracturing bilaterally (a term commonly referred to as eggshell skull) with no brain injury apparent. It is presumed in these circumstances that the skull has absorbed the impact and caused the extensive fracturing in circumstances where otherwise significant forces would be transmitted to the brain.” 72). The final point on which there was a consensus of medical opinion was that there was no evidence that M was suffering from any bone fragility. This was the view not only of the radiologists but also of Prof Bishop, a specialist in paediatric bone disease. 73). It was this combination of circumstances that created the conundrum and led the experts to use extreme language to describe their state of mind at that stage, as summarised by Munby LJ at para 27, by which M’s presentation was variously characterised as unique, unexplained, strange, very unusual, inexplicable, unprecedented and baffling. (b). Enter Dr. Stoodley 74). As described above, in preparation for the retrial this court gave permission for the instruction of Dr. Stoodley, a consultant paediatric neuroradiologist. It is fair to say that Dr. Stoodley has made a significant contribution which has led some of the other experts to modify their view. In addition to the radiological evidence available at the time of the first hearing before Judge Marshall, he had available the results of an MRI carried out on M in September 2012, some 13 months after her admission to hospital, following a referral because of some concerns about her development These revealed some evidence of diffuse axonal injury in the left frontal region of her brain. Furthermore, taking up the suggestion made by Munby LJ, Dr. Stoodley helpfully cited a number of further research papers, of which the most recent and important was “Skull fracture vs accessory sutures: how can we tell the difference?” (Sanchez et al, Emergency Radiology 2010 17:413) to illustrate and support his interpretation of the imaging. 75). Dr. Stoodley observed that, prior to his instruction, the case had progressed on the basis of a number of assumptions, namely (1) that all of the lines (or “lucencies”) seen on the images of M’s skull were fractures (2) that all these fractures occurred at the same time and that the fractures and the frontal soft tissue swelling were related in time, and (3) that, given the extent of the fractures, there would have been inevitable associated brain injury. He frankly suggested that none of these assumptions necessarily stood up to logical analysis. (c). Interpretation of lucencies 76). Dr. Stoodley’s key insight was to suggest that a significant number of the lucencies seen on the images of M’s skull might not be fractures at all. As stated above, Dr. Chapman had acknowledged that some of the lucencies might be fissures, but in addition Dr. Stoodley suggested that some of the longer lucencies might be accessory sutures over and above the normal sutures which lie between the individual skull bones. 77). In the Sanchez paper, the authors explain this phenomenon as follows: “The parietal and occipital bones in particular are common regions for accessory sutures because of their multiple ossification centers. The parietal bone ossifies from two centres while the occipital bone ossifies from six centers. An accessory intraparietal of subsagittal suture is rare but can be seen dividing the parietal bone. They can be explained on the basis of incomplete union of the two separate ossification centers. The occipital bone has a more complex development. The foramen magnum is surrounded by four ossification centers ….This pattern of development can therefore give rise to numerous accessory sutures that could be mistaken for fractures especially with plain film evaluation alone. CT scan with 3D reconstruction is vital in the further characterisation of a questionable fracture.” 78). Analysing radiographic differentiation of skull fractures and accessory sutures, Sanchez and his colleagues observe: “Simple non-depressed skull fractures are sharp lucencies with non-sclerotic edges. In contrast, accessory sutures usually will show a zigzag pattern with interdigitations and sclerotic borders similar to major calvarial sutures …. In terms of bilaterality, accessory sutures are often present on both sides and are fairly symmetric especially in the parietal bones. Occipital accessory sutures can be complex and multiple but are also frequently bilateral.” 79). In this case, Dr. Stoodley suggested that some of the lucencies previously identified as fractures may in fact have been either fissures or accessory sutures. He thought that small lines emerging at right angles from several of the sutures represented fissures. More significant was his suggestion that several of the longer lines were accessory sutures. In particular, he put forward the proposition that the lines crossing the two parietal bones from the coronal suture to the lambdoid suture had the appearance of intraparietal accessory sutures, and the line emanating from the left bottom corner of the lambdoid suture and travelling up the occipital bone before meeting the lambdoid suture at a higher point was an accessory occipital suture. A 3D reconstruction of the images reinforced his interpretation of these lucencies, and in addition demonstrated a faint line, which he interpreted as a further accessory occipital suture, emanating from the right bottom corner of the lambdoid suture and travelling up the occipital bone to the apex of the lambdoid suture close to its junction with the sagittal suture. He noted that there was an element of symmetry in the appearance of the bilateral lucencies which he considered “noteworthy in terms of potentially random events leading to fractures”. 80). Dr. Stoodley was, however, clear that not all of the lucencies seen on the imaging were normal variants. Fissures and accessory sutures are very unusual and to have so many in one individual seemed to Dr. Stoodley to be very unlikely. He thought that some of the lines seen on the images had the appearance of fractures, in particular three lucencies extending from the top of the skull more or less at a right angle to the sagittal suture, two descending the right parietal bone and one the left parietal bone, in each case joining the line crossing the parietal bone which Dr. Stoodley interpreted as an accessory parietal suture. In addition, he considered that a line emanating from the left accessory intraparietal suture had the appearance of a fracture, because (a) it is generally held that sutures do not branch and (b) the images indicated that there was a degree of depression associated with the lucency. 81). A further observation made by Dr. Stoodley, which he considered to be contrary to the views of the other experts, was that it did not necessarily follow that all the fractures occurred at the same time. Indeed, if (contrary to his preferred view) the court concluded that all the lucencies were fractures, he thought it very unlikely that they could be reasonably explained on the basis of a single impact event. Most of the lucencies were not associated with soft tissue swelling and therefore if they were fractures it was possible that they had occurred earlier so that any swelling that might have been caused at the time of the fractures had disappeared by 3rd August when M was presented to the GP. If, on the other hand, the court accepted his view as to the presence of accessory intraparietal and occipital sutures, Dr. Stoodley thought it might be possible to explain the fractures emanating from the sagittal suture and any fractures extending from the intraparietal sutures on the basis of a single impact towards the top of the head. 82). The other experts agreed that the skull fractures may not have occurred at the same time and that this could possibly explain the absence of brain injury. They did not agree, however, on the key issue of whether some of the lucencies seen on the imaging were accessory sutures. In the telephone conference, Dr. Chapman, Dr. Halliday, Mr. Richards and Prof Bishop all stressed that accessory sutures were rare, in particular intraparietal sutures. Following the experts’ telephone conference, further X-rays of M’s skull were taken which revealed no evidence of further fractures. All the lucencies seen on the previous images had disappeared. Dr. Chapman thought that the fact that the lines which Dr. Stoodley proposed as accessory sutures had disappeared was some evidence that they were fractures, since there is some suggestion in the literature that such accessory sutures may continue into adulthood. 83). For the hearing, Dr. Stoodley arranged for colour 3D images to be prepared demonstrating all the lucencies and indicating those which were in dispute between himself and, in particular, Dr. Chapman. In oral evidence, it was established that Dr. Chapman thought there were 9 or 10 fractures, whereas Dr. Stoodley thought there were only four. At the end of his oral evidence in answer to a question from me, Dr. Chapman listed a number of features, based on further research, which supported his interpretation of the lucencies as fractures rather than accessory sutures, namely the rarety of accessory sutures, the absence of Wormian bones, the fact that the lucencies had disappeared on the latest x-rays, the fact that accessory sutures are 5 times more common in men than women, and the fact that unilateral accessory sutures are 5 times more common than bilateral. 84). In his oral evidence, Dr. Stoodley was taken through his analysis of each of the lucencies. He pointed to the symmetrical features which led him to conclude that some of the lines were accessory sutures, in particular the junction of the intrapareital lucencies with the lambdoid suture, and the lower junction of the intraoccipital lucencies with the bottom corners of the lambdoid suture. He accepted that intraparietal sutures are rare – during his career he has only seen one and prior to this case he had never seen them bilaterally – but that was what these lucencies looked like. In contrast, accessory sutures in the occipital bone are more common – he has seen a considerable number, although prior to this case he could not recall seeing two in one bone. He added “the fact that a condition is acknowledged as being rare is not perhaps the important issue – the most important issue is whether the patient has that rare condition or not”
“if you want to look at whether a bone is likely to fracture it will have intrinsic properties – the material the bone is actually made of – and extrinsic properties, which is more to do with the micro-architecture of bone and the macrostructure at a whole tissue level …. Often we find the abnormality of both the intrinsic and extrinsic material properties go together, so if the bone is intrinsically abnormal then the architecture is abnormal as well …. The fissures are unlikely to be empty spaces. They are likely to have sheets of membrane over them which may in due course turn to bone and that may be reasonably thick in nature. Under that you might find that there was an increased overall flexibility of the skull bone itself. That is speculation and I don’t have any evidence to back it up.” 93). On the basis of his reading of the literature, Prof Bishop told the court that there was no known association between fissures and an increased propensity to fracture. He drew a distinction between propensity to fracture and bone immaturity. The propensity to fracture depends, he suggested, not on its immaturity but rather on the intrinsic and extrinsic factors cited above. 94). Whether or not the presence of a number of fissures and accessory sutures increases the likelihood of skull fracture has no bearing on the susceptibility to fracture in the rest of the skeleton. Prof Bishop pointed out that, whereas the skull develops out of membrane, most other bones, including the long bones and the ribs, develop out of cartilage. The process of ossification from cartilage is different from the development from membrane. Thus whether or not there was any link between the immaturity of the skull bones and any propensity to skull fractures, there was no known link between immaturity of the skull bones and propensity to fracture elsewhere in the skeleton. (e). Brain damage 95). Dr. Stoodley confirmed that that there was no evidence of brain damage or other intracranial injury from the scans performed in 2011. He added, however, that it was possible that the diffuse axonal injury seen on the later MRI performed in September 2012 related back to the incident or incidents that caused the skull fractures in 2011. The fact that M did not have any abnormal neurology would not exclude the diffuse axonal injury being related to an acute event at or around that time because “frontal pathology … is often clinically silent”
“M was in her chair placed on the sofa; I picked her up and fed her in my arms whilst I sat on the sofa; she was fine and took her bottle. She had spilt some milk and I needed some wipes to clean it up. We have a solid wood coffee table in the living room which was further away from the sofa than it usually is on that occasion as L was playing with his toys. I stood up to get to the wet wipes and was pretty much stood up fully. M was cradled in my left elbow and I was reaching with my right hand for the wipes. She suddenly wriggled and I lost grip; she fell out of my arm. I heard a big thud on the coffee table and then another one as she fell onto the floor. M definitely hit the coffee table first; I didn’t see how she hit it/which part first but the noise also made it clear to me that she had hit it (the thud was clearly from an impact on wood). A hand towel was draped over her body whilst in my arms to prevent milk getting on her clothes and my eyes were focussing on the baby wipes I was reaching for. It all happened in a split second and the towel concealed my view…. On seeing M on the floor I panicked and couldn’t pick her up quickly enough. She was lying body faced down with her head turned to the side. I think I grabbed her under her armpits to pick her up. She was crying as I was picking her up, not a whinge type cry but a full blown cry; it was a very sudden and very loud cry. I tried to console her by talking to her and cuddling her. I checked her over for any signs of injury; I felt all of her limbs (she was wearing a body suit – short sleeved version I think). She had no marks on her. I also felt her neck and head. I was just instinctively checking for any obvious damage by smoothing my hand over her skin. She calmed down to a more normal cry whilst I was cuddling her. I think T [the mother] came back into the house after about 5-10 minutes after the fall. M was still crying. T asked me why she was crying when she came back; I replied I did not know. T took M and she then settled within about five minutes or maybe a little longer. Having not seen any obvious sign of injury, I hoped M was okay but I remained terrified as it was a significant incident. I was scared to tell T as I was worried about everything that had happened in Ipswich and I didn’t want to worry T or get social services involved. Although it was an accident, we had already been investigated on numerous occasions due to malicious referrals. I know that this was incredibly stupid of me and that I should have immediately told T what had happened. I haven’t forgiven myself for dropping M or from keeping it from T. M seemed to be fine during the evening. I think she was fed by T later that night. I remained scared, praying that she would be okay. When I held M later that night I subtly checked her again for any obvious sign of injury; I did not want T to know what I was doing though and so I was discreet.” 128). The mother’s account is that she recalls hearing M crying whilst she was outside but knew that she should not interfere as the baby needed to get used to the father caring for her. She told the police (and confirmed in oral evidence to me that it was correct) that she had come in from the garden twice. On the first occasion, the crying stopped just as she entered, the father and M were on the sofa, she heard M burp, and thought that the feeding was over. She then went outside and the crying resumed. When the mother returned indoors, she found M looking very red faced and crying loudly. She was sitting in her chair and the father was on the sofa. The mother said that she asked the father what was wrong but he remained silent. She assumed that it was because M was upset at being with the father and so she picked her up. She gave her some calpol. It took at least half an hour to 40 minutes before M quietened down. In oral evidence, the mother said that M had been “as miserable as sin”
“it was a large lump and the right side of her face was swollen.”
