“…This finding is expected to be helpful for the surgical treatment of craniosynostosis. Our findings suggest that the multidirectional cranial distraction osteogenesis method (a method targeting equal correction in each 3D direction) 25) is more physiological than single-direction bone extension in cases of multiplesuture craniosynostosis. Furthermore, this study's new 3D growth-related parameters are expected to be an important index, such as early detection when considering whether suturectomy should be performed for sagittal synostosis before 6 months of age.…”

In this study, we aimed to evaluate the longitudinal changes in the cranial shape of healthy Japanese infants using a three-dimensional scanner and construct a normal values database for the growth process. Preterm infants (gestational age < 37 weeks), infants with neonatal asphyxia (5-minute Apgar score of <7), and patients who started helmet therapy for deformational plagiocephaly were excluded from this study. The first scan was performed at approximately 1 month of age, followed by two scans conducted at 3 and 6 months of age. The parameters considered were as follows: cranial length, width, height, circumference, volume, cranial vault asymmetry index, and cephalic index. A cranial vault asymmetry index >5% was defined as deformational plagiocephaly. Changes in each parameter were examined using repeated-measures analysis of variance classified by sex and deformational plagiocephaly status. The rate of increase in each parameter was also examined. In total, 88 infants (45 boys and 43 girls) were included in this study. All growth-related parameters were noted to increase linearly with time. Sex differences were observed in all parameters except cranial length. Deformational plagiocephaly was found to have no effect on growth-related parameters. Cranial volume increased by 60% from 1 to 6 months of age. The growth almost uniformly influenced the rate of increase in volume in each coordinate axis direction. Overall, the mean trends in three-dimensional parameters in infants up to 6 months of age were obtained using a three-dimensional scanner. These trends could be used as a guide by medical professionals involved in cranioplasty.

Distraction osteogenesis is a surgical technique widely used in orthopedic surgery for treatment of various pathological skeletal conditions, namely correction of limb-length discrepancies, angular deformity and treatment of distal and severely comminuted fractures, or bone defects through bone transport. The basic principle consists on the gradual distraction of two bone segments, previously submitted to a corticotomy and promptly fixated generally using of circular external skeletal fixation. New bone tissue is generated in the bone gap between the two segments. This review aims to describe the biological fundaments and principles of this technique, the surgical steps performed to attempt distraction osteogenesis, and its possible complications with main focus on its application in companion animals.Bone Grafts 2 latency period will be applied, and (iv) the distraction rate (DR) must be appropriate for the level and type of bone in which osteogenesis is being performed [5].After the separation of both segments, three temporal phases of DO can be defined: latency period, distraction period, and consolidation period [3]. Osteotomy and corticotomyThe DO procedure begins with the transverse section at a diaphyseal or metaphyseal level of the long bone to be elongated. Ilizarov described three methods to create fractures, including osteotomy, corticotomy, and osteoclasis. The osteogenic potential of the osteotomy or corticotomy depends on three main factors: the localization in bone, the type of technique used, and the latency period subsequently applied [6, 7].Regarding the localization, some researchers in the past referred that the bone lengthening should be performed in the middle of the diaphysis of the long bone, and when necessary elongation was obtained, a bone graft from the ilium crest could be applied on the distraction focus to promote its consolidation. Later, Ilizarov recognized the metaphysis as the ideal site for the osteotomy, due to its massive trabecular bone area, rich in collateral vascularization, and higher potential for fracture recovery. Other researchers compared the regenerated bone quality at the diaphysis and metaphysis after DO, while using different latency periods. In the metaphysis, latency periods of 0 and 7 days allowed a greater osteogenesis and a faster remodeling and consolidation, when compared to the diaphysis elongation. A latency period of 14-21 days was associated with a premature consolidation in both regions. Bone mineralization of the newly formed tissue was faster at the metaphysis than at the diaphysis. Curiously, when there was no latency period, the distraction was successful and the consolidation faster. The latency of 7 days did not reveal the risk of premature consolidation; however, the consolidation and bone formation were slower than where there was no latency period. Post mortem torsion and bending test revealed that the bone tissue elongated on the metaphysis was tougher and more resistant. Histologically, the osteogenesis is observed to be based on intra-mem...

“…This technique involves the application of graduated tension to the bone tissue using external fixation devices. The main advantage of this procedure is the reduced invasiveness in comparison with open cranial vault remodeling, since the dissection of the dura is limited [37]. However, it shows limitations such as long treatment duration and, in some cases, secondary surgical interventions.…”
