Histology of a Harris line in a XXXX distal tibia.

@entity1 @entity1733
UNASSIGNED: Identification and diagnosis of Harris lines (HLs) is usually achieved using radiography. To date, histological methods have been mainly implemented in research exploring the underlying processes of @entity1733 deposition using longitudinal sections taken from animal bone. Here, a new insight into @entity1733 formation is provided following transverse histological sectioning in a @entity1 specimen. A distinct @entity1733 was identified macroscopically, and from a radiograph, in a left distal tibia taken from an adult @entity1 male. Transverse sections were taken through the @entity1733 , and also from trabeculae immediately superior and inferior to the @entity1733 . Thin sections were produced following standard histological procedures. Micrographs were captured using a digital microscope camera. Trabeculae immediately superior and inferior to the @entity1733 displayed no indication of abnormal growth, exhibiting abundant osteocyte lacunae and a lamellar structure. However, the micro-anatomy of the @entity1733 was characterised by the following three main features: (1) non-lamellar appearance, (2) a complete lack of osteocyte lacunae, and (3) presence of irregularly distributed tubular structures. These three histological features indicate a specific process of bone deposition, implying that trapping of osteoblasts may not take place during @entity1733 formation. Pictorial and descriptive records of @entity1733 histology are provided, aiding current understanding about the nature of @entity1733 , its identification from histology, and serving as a reference point for future comparative research.
