How would you describe this fracture ?

analyse_media
This is a veterinary VD (ventrodorsal) pelvic radiograph of a patient labeled "SABNAM" (Vetcare Diagnostics, Indore, 23.07.2026). There is severe polytrauma to the right hindquarter. Here is a structured description:

Radiographic Findings

1. Right Femoral Fracture

  • Location: Mid-to-distal diaphysis of the right femur
  • Type: Complete, highly comminuted, oblique/spiral fracture
  • Displacement: Severe overriding with the distal fragment displaced laterally and proximally; proximal fragment displaced medially
  • Butterfly fragment: A distinct wedge-shaped (butterfly) comminuted fragment is visible free-floating between the two main fragments
  • Soft tissue: Marked soft tissue swelling surrounds the right thigh

2. Unstable Right Hemipelvic Fracture (Triple Pelvic Fracture)

Three separate fracture lines make the right hemipelvis completely unstable:
  • Right ilium: Complete oblique fracture of the ilial body - the caudal segment (carrying the acetabulum) is displaced medially, significantly narrowing the pelvic canal
  • Right pubis: Fracture of the right cranial pubic ramus
  • Right ischium: Fracture of the right ischial table/body
  • Hip joint (coxofemoral): The femoral head appears to remain seated within the acetabulum (no luxation), but the entire acetabular unit is displaced medially due to the surrounding pelvic fractures

3. Left Side

  • Left femur, left hip joint, and left hemipelvis appear intact and normal

Summary

This patient has suffered severe right-sided hindquarter polytrauma, most likely from high-energy blunt force (e.g., vehicular trauma):
  1. Comminuted, displaced mid-diaphyseal right femoral fracture with a butterfly fragment and marked overriding - this will require surgical fixation (intramedullary pin + cerclage wires, or a bone plate)
  2. Unstable right hemipelvic fracture (ilium + pubis + ischium) with medial collapse of the acetabular segment and pelvic canal narrowing - the ilial fracture in particular warrants plate fixation to restore pelvic stability and canal diameter
The combination of a femoral fracture AND an ipsilateral unstable hemipelvic fracture is a serious, complex surgical case requiring careful anaesthetic and post-operative planning.
