A Salter—Harris SH injury see below at any age may result in significant and persistent deformity due to a physeal growth disturbance. It should be emphasized that owing to lack of immobilization, all long bone fractures from abuse are subject to repetitive trauma. Some abusive fractures should be regarded not as single injuries, but rather as a sequence of traumatic events. Measuring the thickness of the callous formation is a more objective way of guiding the radiologist in estimating the age of the fracture. From the age of 20 years on, this process will take approximately 20 weeks Healing patterns of clavicular birth injuries as a guide to fracture dating in cases of possible infant abuse. It is not unusual to see acute and early organizing hemorrhage pathologically in older fractures, and in the absence of gross morphologic features suggesting a second injury, these findings are usually attributable to motion and microtrauma of an immobilized fracture. Thereafter, callous thickness was measured and recorded for each stage. Chronic and remote fractures It is often crucial for forensic reasons to estimate when chronic or remote fractures may have occurred. There is a right tension pneumothorax. The principles of dating skeletal injuries in this chapter are most applicable to the tubular bones. The stage of induction involves both a destructive phase, with the removal of hemorrhage and damaged tissue, and a constructive phase, with the formation of osteoid and bone. Many variables will affect other earlier elements of histologic healing, such as the production of hemorrhage and inflammatory change at the injury site. Six radiological features of rib fractures evaluating the appearance of the callous formation C stage and fracture line F stage were assessed. The duration of time to callus consolidation is affected by other previously noted variables occurring with abusive injuries including the lack of immobilization of fracture fragments and a higher likelihood of repetitive injury. Note that the fracture margins are relatively distinct. Two of the variables affecting abuse-related fractures, lack of immobilization and repetitive trauma, do not generally pertain to these obstetric injuries. There was no history of a previous fracture, but a proximal tibial fracture was encountered at postmortem SS. Special attention is given to infants, who are most often affected by inflicted injury and are at greatest risk for a poor outcome Other studies have focused exclusively on later stages of fracture healing such as callus formation, excluding earlier SPNBF from assessments This process begins near the fracture margins and proceeds centrifugally away from the injury site. The duration of acute inflammation is typically a few days, and is considerably shorter in infants and children than in adults. There are abundant examples of abusive appendicular and axial skeletal injuries in various stages shown elsewhere in this text see Chapters 2 —5, 17 , and As healing occurs, there is gradual resumption of normal enchondral ossification. This applies even when there has been a single abusive traumatic episode. When there have been multiple episodes of abuse, secondary abusive trauma to original fracture sites may substantially affect the healing process and complicate dating assessments. Callus develops around the ends of a fractured bone by cellular organization within the fracture hematoma, and ultimately unites the fracture fragments.

It should be emphasized that owing to lack of immobilization, all long bone fractures from abuse are subject to repetitive trauma. The customary approach to the study of the healing process of inflicted injuries is to draw upon the existing knowledge base of the biomechanics, imaging, and histopathology of accidental injury. There is active proliferation of osteoblasts within the osteogenic layer of the periosteum and new subperiosteal woven bone is deposited with increasing laminated trabecular density over the ensuing weeks. This process begins near the fracture margins and proceeds centrifugally away from the injury site. The difficulties of dating cranial and spinal injuries are covered in Chapters 17 and 21 respectively. Capillaries, precursor cells, and strands of collagen must be formed in the damaged tissue before the definitive elements of osteoid and bone are produced. Patient age Based upon experience with accidental fractures of known age, as well as patterns of healing following the recognition of abusive injuries, it is evident that fractures in infants generally progress more rapidly through all radiographic phases of healing than injuries in older children. The duration of acute inflammation is typically a few days, and is considerably shorter in infants and children than in adults. Two of the variables affecting abuse-related fractures, lack of immobilization and repetitive trauma, do not generally pertain to these obstetric injuries. The fracture line is relatively sharply defined. Show more authors Abstract Aim: The fact that infant fractures evolve more rapidly through all histologic phases of healing when compared to older children is particularly notable with respect to the production of fibrocartilaginous matrix in the callus.

  1. Capillaries, precursor cells, and strands of collagen must be formed in the damaged tissue before the definitive elements of osteoid and bone are produced. A first important consideration is the nature of the clinical history available.

  2. Ongoing inflammation and removal of nonviable tissues lasts for several days at a minimum, but more often up to 3—4 weeks. In the following discussion we attempt to distill the published evidence on fracture healing and meld it with the clinical experience of the current P.
