The monitoring of bone fractured healing using Alkaline phosphatase, calcium ion and inorganic phosphate was evaluated among patients with fractured bone in two different centers, Alex Ekwueme Federal University Teaching Hospital Abakaliki and Bone Setters Home, Onueke, Ezza in Ebonyi State between August 2017 and September 2018. : A total of 90 adults patients from 18 years to 78 years were examined using phenolphthalein monophosphate colorimetric end point method. Out of the 90 patients, 30 were healthy normal subjects, another 30 were patients in AE-FUTHA while the remaining 30 patients were in bone setter home. : Patients without bone fracture had the least mean serum level of alkaline phosphatase, 28.5 ± 9.0µl followed by those admitted in bone setter home with a mean serum level of 38.2±17.9µl while patients admitted in AE-FUTHA had the highest mean serum level of 41.4±6.5µl (P<0.05). The mean serum level of calcium was significantly higher 10.9± 2.6mg/dl in healthy normal patients compared to mean serum level of 9.2 ± 3.3mg/dl and 7.4 ± 1.3mg/dl for patients admitted in AE-FUTHA and bone setter home respectively. The mean serum level of inorganic phosphate indicate that patients admitted in bone setter home had the highest mean of 4.1 ± 1.0mg/dl followed by patients admitted in AE-FUTHA 3.4 ± 0.2mg/dl while that of healthy normal individuals had the least mean serum level of 3.2 ± 0.5mg/dl. : Out of the three parameters examined, alkaline phosphatase test was more precise, reliable and patient doctor friendly; hence it can be used as a veritable tool to monitor the process of bone fracture healing effectively.

This paper comprehensively reviews the various experimental and numerical techniques, which were considered to determine the fracture characteristics of the cortical bone. This study also provides some recommendations along with the critical review, which would be beneficial for future research of fracture analysis of cortical bone. Cortical bone fractures due to sports activities, climbing, running, and engagement in transport or industrial accidents. Individuals having different diseases are also at high risk of cortical bone fracture. It has been observed that osteon orientation influences cortical bone fracture toughness and fracture mechanisms. Apart from this, recent studies indicate that fracture parameters of cortical bone also depend on many factors such as age, sex, temperature, osteoporosis, orientation, location, loading condition, strain rate, and storage facility, etc. The cortical bone regains its fracture toughness due to various toughening mechanisms. Owing to these factors, several experimental, clinical, and numerical investigations have been carried out to determine the fracture parameters of the cortical bone. Cortical bone is the dense outer surface of the bone and contributes to 80%–82% of the skeleton mass. Cortical bone experiences load far exceeding body weight due to muscle contraction and the dynamics of motion. It is very important to know the fracture pattern, direction of fracture, location of the fracture, and toughening mechanism of cortical bone. A basic understanding of the different factors that affect the fracture parameters and fracture mechanisms of the cortical bone is necessary to prevent the failure and fracture of cortical bone. This review has summarized the advancement considered in the various experimental techniques and numerical methods to get complete information about the fracture mechanisms of cortical bone.

Abstract Aim We present our experience in the management of frontal bone fractures using the previously described radiologic classification of frontal bone fractures. Methodology A retrospective study was conducted, which reviewed the medical records and computed tomographic (CT) scan images of patients with frontal bone fracture from January 2016 to February 2019. Patients with complete medical records and a follow-up of minimum 1 year were included in the study. Demographic details, mechanism of injury, associated intracranial injuries, maxillofacial fractures, management, and complications were analyzed. CT scan images were used to classify the frontal bone fractures using the novel classification given by Garg et al (2014). The indications for surgical treatment were inner table frontal sinus fracture with cerebrospinal fluid (CSF) leak, intracranial hematoma with significant mass effect requiring surgical evacuation, and outer table comminuted fracture that is either causing nasofrontal duct obstruction or for cosmetic purpose. Results A total of 55 patients were included in the study. Road traffic accidents as the commonest cause of frontal bone fractures. The most common fracture pattern was type 1 followed by type 5 and depth B followed by depth A. Four patients presented with CSF rhinorrhea. CSF rhinorrhea was more frequent with fracture extension to the skull base (depth B, C, D), which was statistically significant (p < 0.001). Conclusion Frontal bone fracture management has to be tailor-made for each patient based on the extent of the fracture, presence of CSF leak, and associated intracranial and maxillofacial injuries.

Objectives: The healing process of a bone fracture goes through many phases. The hard callus phase was critical where the original structure was conducted. The hard callus growth depends on osteoblasts and osteoclasts active, and this condition can be analyzed on the radiograph. This study aimed to examine the analysis of bone fracture healing between osteoblasts and osteoclast numbers and radiographic patterns. Materials and Methods: The study used 12 male Wistar rats with an incomplete fracture in the right femur made by a dental tapered bur with 0.3 mm in length and 0.2 mm in depth. Digital radiographic examinations were carried out on days 0, 5, 10, 17, and 25 after fracturing in a lateral position. Furthermore, a radiographic analysis was performed using Image-J to obtain changes in the value of length and depth in the healing area. The research was conducted to find the radiopaque and radiolucent patterns and the number of osteoblasts and osteoclasts. Results: This study resulted in a change in the radiograph pattern. Callus formation resulted in fracture areas with a smaller distance from day 0 to day 25. The bone healing process begins with granulation tissue formation, followed by the gradual replacement of the connective tissue and bone. This process is comparable to the increase in osteoblasts up to day 25, which blocks bone resorption. Osteoclasts regulate bone resorption, and their number increases after 10 and 17 days to replace bone formation. Osteoclasts decline after 25 days because osteoblasts inhibit them, which control bone formation. Conclusion: The conclusions were obtained there are changes in the radiograph pattern. The radiopaque increased while the radiolucent decreased; the osteoclast pattern tended to be stable and lowered while the osteoblasts increased during the fracture healing process. The correlation of all the factors is very closely related.
