Fracture healing

Why do fractures unite?

Because the bone is broken!

Healing cascade: indirect healing Inflammation 0 – 5 days

– Haematoma– Necrotic material – Phagocytosis

Repair: 5 – 42 days– Granulation tissue– Acid environment– Periosteum – osteogenic

cells– Cortical osteoclasis

Remodelling– years

What is the difference between direct and indirect

bone healing?

Page 7: Upper Extremity Trauma. 2 How do fractures heal?

Indirect healing – healing by Callus

Unstable Callus stabilises #

Direct healing between cortices

Page 8: Upper Extremity Trauma. 2 How do fractures heal?

8

Direct bone healing – the response to rigid fixation Only occurs in

absolute stability of the fracture

Does not involve callus formation

Requires good blood supply

What are the aims of fracture treatment?

Page 10: Upper Extremity Trauma. 2 How do fractures heal?

10

AIMS OF FRACTURE TREATMENT

Restore the patient to optimal functional state

Prevent fracture and soft-tissue complications

Get the fracture to heal, and in a position which will produce optimal functional recovery

Rehabilitate the patient as early as possible

What factors effect fracture healing?

Page 12: Upper Extremity Trauma. 2 How do fractures heal?

12

FACTORS AFFECTING FRACTURE HEALING

The energy transfer of the injury

The tissue response– Two bone ends in opposition or compressed– Micro-movement or no movement– Blood Supply (scaphoid, talus, femoral and humeral

head)– Nerve Supply– No infection

The patient– smoking

The method of treatment

DIAGNOSING THE BONE INJURY

Clinical assessment

– History - Co-morbidities

– Exposure/systematic examination

“First-aid” reduction

Splintage and analgesia

Radiographs– Two planes including joints above and below area

of injury
