Radiography: shoulder

Contributor(s): Justin Goggin, Patsy Whelehan

Introduction

  • Accurate centering is essential when radiographing any joint.
  • High resolution film-screen combinations are required.
  • A grid is necessary when tissue thickness >10 cm.
  • kV should not exceed about 60.
  • Close collimation is essential to avoid scatter.
  • If general anesthesia is not used, then sedation with analgesia is suggested.
  • The film must include the whole joint, with soft tissues, must be correctly exposed and developed and free from movement blur and artefact.
  • The anatomical marker must be clearly visible, along with the patient's identification, the date, and the name of the hospital or practice.

Uses

  • → An important diagnostic aid in determining the cause of lameness arising from the shoulder.
  • → Bony injury: fracture or dislocation Shoulder: luxation - traumatic Shoulder dislocation - radiograph CdCr.
  • → Osteochondrosis Shoulder: osteochondrosis Shoulder OCD - radiograph lateral.
  • → Bony neoplasia Bone tumor proximal humerus - radiograph , or soft tissue neoplasia Synovial cell sarcoma , invading bone.
  • → Investigation of soft tissue injury.
  • → Inflammatory, infectious or degenerative osteoarthrosis.
  • → Congenital elbow luxation.

Advantages

  • Non-invasive.
  • Low cost and readily available.

Disadvantages

  • Poor positioning can make subtle pathology impossible to detect.
  • The presence of severe pain can make the procedure difficult in a conscious patient.
  • Radiation exposure to patient/personnel.
