Fracture Principles for NEET-PG
Fracture principles cover the classification, healing, and management of broken bones, forming the foundation of orthopaedic questions in NEET-PG. The core skills are describing a fracture, understanding the stages of healing, recognising complications, and applying the reduce, hold, rehabilitate framework. A fracture is a break in bony continuity, described by pattern such as transverse, oblique, spiral, or comminuted, whether it is open or closed, its displacement, and whether it is intra-articular. Open fractures communicate with the exterior and are classified by the Gustilo-Anderson system, carrying a high infection risk that mandates early antibiotics, tetanus prophylaxis, debridement, and stabilisation. Fracture healing proceeds through haematoma formation, inflammation, soft callus, hard callus, and remodelling, and can be primary healing with rigid fixation or secondary healing through callus with relative stability. Management follows three principles: reduction to restore alignment, holding by casting, traction, or internal or external fixation, and rehabilitation to restore function. Complications are divided into immediate, early, and late, including haemorrhage, neurovascular injury, compartment syndrome, fat embolism, infection, delayed union, non-union, malunion, and avascular necrosis. Compartment syndrome is a surgical emergency signalled by pain out of proportion and pain on passive stretch. In children, remodelling potential is high and the growth plate is a special concern classified by the Salter-Harris system. Knowing Gustilo grading, healing stages, and compartment syndrome are consistent anchors.

Key points
- **Fracture description:** Describe site, pattern (transverse, oblique, spiral, comminuted), open or closed, displacement, angulation, and intra-articular extension.
- **Open fracture care:** Open fractures need early antibiotics, tetanus prophylaxis, thorough debridement, and stabilisation to reduce infection risk.
- **Gustilo-Anderson:** Classifies open fractures by wound size, contamination, and soft tissue damage, guiding prognosis and management.
- **Healing stages:** Haematoma, inflammation, soft callus, hard callus, and remodelling. Callus formation indicates secondary bone healing.
- **Primary vs secondary:** Rigid anatomical fixation gives primary healing without callus, while relative stability gives secondary healing through callus.
- **Management triad:** Reduce to restore alignment, hold with cast, traction, or fixation, and rehabilitate to regain movement and function.
- **Compartment syndrome:** A surgical emergency. Pain out of proportion and pain on passive stretch are earliest signs. Treat with urgent fasciotomy.
- **Fat embolism:** Occurs after long bone fractures with dyspnoea, confusion, and petechiae, typically 24 to 72 hours after injury.
- **Union problems:** Delayed union is slow healing, non-union is failure to heal, and malunion is healing in poor position.
- **Avascular necrosis:** Fractures of the femoral neck, scaphoid, and talus risk avascular necrosis due to their retrograde blood supply.
- **Paediatric fractures:** Children have high remodelling potential. Growth plate injuries are classified by the Salter-Harris system and can disturb growth.
Frequently Asked Questions
What are the stages of fracture healing?
Healing proceeds through haematoma formation, inflammation, soft callus, hard callus, and remodelling, with callus marking secondary bone healing.
What is the management principle for fractures?
The framework is reduce to restore alignment, hold with cast, traction, or fixation, and rehabilitate to recover movement and function.
Why are open fractures an emergency?
Open fractures communicate with the exterior and carry a high infection risk, so they need early antibiotics, tetanus cover, debridement, and stabilisation.
What are the earliest signs of compartment syndrome?
Pain out of proportion to the injury and pain on passive stretching of the muscles are the earliest signs, requiring urgent fasciotomy.
Which fractures are prone to avascular necrosis?
Fractures of the femoral neck, scaphoid, and talus risk avascular necrosis because of their tenuous retrograde blood supply.
