Abstract

Radiographic Evaluation of the Appearance and Closure Time of Growth Plates of Radius and Ulna Bones in Nigerian Indigenous Dogs

Highlights

Monitoring the radius and ulna bones is necessary in veterinary radiology as it provides a guide to surgeons on the choice of surgical procedures to be performed in the growth plate region considering the time at which the growth plate of these bones appears, reach their proper anatomical shape and fuse.Growth plates are known asphyses, epiphyseal plate, metaphyseal growth plate, epiphyseal cartilage and epiphyseal disk [1]
The radiolucent space located between the epiphysis and the metaphysis is the growth plate which appeared after the appearance of secondary ossification centers of each bone
The first growth plate to appear was the distal radius at 2 weeks (Figure 2) as a small ovoid structure which was present in 12 dogs (6 males and 6 females) but absent in 4 dogs which appeared at 3 weeks in others, followed by the proximal radius which appeared at 5 weeks (Figure 5) in all the dogs, the distal ulna that appeared at 6 weeks (Figure 6) in all the dogs and the proximal ulna that all appeared at 8 weeks (Figure 8) for all the dogs

Summary

Introduction

Growth plates are known asphyses, epiphyseal plate, metaphyseal growth plate, epiphyseal cartilage and epiphyseal disk [1]. They are the endochondral ossification areas of long bones [2] which are specialized cartilages extending longitudinally between the epiphysis and metaphysis of immature long bones. The growth plate appears radiolucent on radiographs [3] which closes as the animal matures and at this age of maturity, the epiphysis fuses with the metaphysis to become a single bone [4]. The objective of this study was to observe the time of appearance, sequential thickness and closure of growth plates of radius and ulna bones of male and female Nigerian indigenous dogs by using radiograph
