🦴 Station 10 — X-Ray Interpretation of Fracture/Dislocation and Initial Limb Management
Rapid Revision • X-Ray Interpretation • Initial Limb Care • Viva
🎯 Task
You are provided with radiographs of an injured limb. Identify the abnormality, describe the injury systematically including its site, type, displacement or angulation where applicable, and demonstrate or describe the appropriate immediate immobilization and initial management.
⚡ Model Station Answer — What to say in the exam
Interpretation: I would first confirm the patient, side, anatomical region and radiographic views, then inspect alignment, bones, joints and soft tissues systematically.
Injury description: I would identify the affected bone or joint and state the exact site and fracture pattern or direction of dislocation. For a fracture, I would describe displacement, angulation and articular involvement where visible.
Initial management: I would assess and document distal neurovascular status, provide analgesia and immobilize the limb in an appropriate splint while avoiding unnecessary movement.
Completion: I would reassess neurovascular status after immobilization and arrange appropriate orthopedic review and further management.
🔎 Stepwise Procedure / Approach
-
- Confirm the radiograph. Check patient identity, anatomical region, side marker, date and available views; ideally review at least two projections.
-
- Assess image adequacy. Ensure the relevant anatomy is visible and identify whether the image is AP, PA, lateral or another projection.
- Review systematically. Assess alignment and joints → bones and cortices → joint spaces → soft tissues without stopping after the first abnormality.
- Identify the injury. Decide whether the main abnormality represents a fracture, subluxation or complete dislocation.
- Describe a fracture. State the bone, side, proximal/middle/distal site, fracture pattern such as transverse, oblique, spiral or comminuted, and whether the articular surface is involved where visible.
- Describe displacement. Describe the position of the distal fragment, including translation and angulation; mention shortening or rotation only when reasonably assessable.
- Describe a dislocation. Name the affected joint and describe the direction of displacement of the distal component relative to the proximal component.
- Assess the injured limb clinically. Look for deformity, swelling or an open wound and assess distal pulse, capillary refill, sensation and relevant motor function before immobilization.
- Immobilize safely. Support the limb in a comfortable position using an appropriate padded splint or sling. For a long-bone injury, stabilize the fracture and adjacent joints where appropriate without forceful manipulation.
- Reassess and escalate. Repeat distal neurovascular examination after splinting, provide analgesia and arrange definitive orthopedic assessment; suspected open fractures or neurovascular compromise require urgent escalation.

Systematic X-Ray Recognition: Fracture vs Dislocation
🎥 Practical Video
This demonstration reinforces a systematic approach to musculoskeletal radiographs and shows how fractures should be identified and described rather than relying on a quick visual impression.
📝 Important Viva Questions
Answer: Confirm the patient, anatomical region, side marker, date and available projections, and assess whether the radiograph is technically adequate.
Answer: A fracture or displacement may be inapparent on one projection. Two approximately perpendicular views provide better assessment of the fracture and its alignment.
Answer: Describe the position of the distal fragment relative to the proximal fragment, including direction of translation and angulation.
Answer: Subluxation is partial loss of normal joint congruity, whereas dislocation is complete loss of normal articulation between the joint surfaces.
Answer: Assess distal pulses, capillary refill, skin colour or temperature, sensation and relevant motor function.
Answer: Immobilization can reveal or worsen vascular or nerve compromise if the splint is too tight or limb alignment changes. Post-splint findings should therefore be documented.
Answer: Determine whether the fracture is open by looking for a wound communicating with the fracture region, because this requires urgent specialist management.
