Introduction

This dataset aims to identify and annotate specific spinal conditions and interventions in X-ray images for medical analysis. The classes include:

• Osteophytes: Bone spurs that form on the vertebrae.
• Surgical Implant: Medical devices placed during surgery.
• Vertebral Collapse: Compressed or fractured vertebrae.

Object Classes

Osteophytes

Description

Osteophytes, or bone spurs, appear as small, irregular protrusions on the edges of vertebrae.

Instructions

• Identify and annotate any protrusions along the vertebral edges that appear like small spikes or extra bone growths.
• Ensure the bounding box captures the full extent of the spur without including adjacent vertebrae unless directly connected by the spur.
• Do not annotate normal vertebral contours or areas without distinct protrusions.

Surgical Implant

Description

Surgical implants are visible mechanical devices, often appearing as screws or cages, used to stabilize the spine.

Instructions

• Annotate devices that have a distinct mechanical appearance, such as screws, rods, or cages within the spinal region.
• The bounding box should encompass the entire implant, including any screws or extensions that are visible.
• Do not annotate areas where the mechanical structure is not visible or indistinct.

Vertebral Collapse

Description

Vertebral collapse occurs when a vertebra appears significantly compressed or fractured, often leading to a change in shape.

Instructions

• Annotate vertebrae that show clear signs of compression or alteration in shape compared to adjacent vertebrae.
• Ensure the bounding box tightly encompasses the affected area, capturing the collapsed structure.
• If the shape of the vertebra resembles adjacent normal vertebrae, do not annotate.
