Who has had a fracture?.....
![Page 4: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/4.jpg)
What is a Fracture?
• A fracture is a break in the continuity of a bone or a loss of continuity in the substance of a bone
![Page 5: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/5.jpg)
Clinical signs of a fracture
• A deformity that can be seen or felt
• Pain on stressing the limb
• Abnormal movt in a limb due to movt at # site
• Crepitus or grating between bone ends
• Impaired function
• Swelling at the fracture site
• Tenderness at # site
![Page 6: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/6.jpg)
Fractures
![Page 7: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/7.jpg)
Causes of fractures• Direct trauma
– caused by external forces which exceed the strength of the bone.
– direct violence e.g. RTA, a blow
![Page 8: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/8.jpg)
![Page 9: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/9.jpg)
![Page 10: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/10.jpg)
or
• Indirect trauma– Fracture results from twisting or rotational
forces being applied to the bone
– e.g football studs planted, rotation force applied to the limb resulting in spiral # of the tibia
![Page 11: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/11.jpg)
or
• Pathological fracture– bone is already weakened or diseased
– fracture because the bone’s internal structure is weakened
• Stress fracture– Caused by repeated excessive loading of a bone, the
cumulative forces result in a break
![Page 12: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/12.jpg)
Types of fracture:
• Classified by skin damage• Or shape of fracture • Or displacement
![Page 13: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/13.jpg)
Classified by skin damage:
• Open: skin’s broken either by external force or internal one
• Closed: simple fracture
![Page 14: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/14.jpg)

Stages of fracture healing:
• Stage 1: Haematoma (0–2 wks)
• Stage 2: Cellular proliferation (2-6 wks)
• Stage 3: Callus formation• Stage 4: Consolidation stage (6-12 wks)
Ossification occurs 12 -26 wk callus matures
• Stage 5: Stage of remodelling (1-2 yrs)
![Page 22: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/22.jpg)
Why do physios treat fractures?
• Aim to 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

Management of soft tissue injuries
• Acute Injury• PRICE:
– Protect– Rest– Ice– Compression– Elevation
![Page 49: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/49.jpg)
Icing• Limits Inflammatory process• First 48-72 hours• Methods: - Crushed ice in a towel, frozen veg, Ice
bath, Chemical ice packs (pitch-side), Freeze spray / cryogel
• Application: - 10 mins every 2 hours
• Dangers of leaving ice on too long - Ice burn - Never damage - Increase in blood flow
![Page 50: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/50.jpg)
The aims of early management
The management of STI in the first 72 hours: • to reduce pain • to reduce local tissue temperature • to limit and reduce inflammatory fluid• to reduce metabolic demands of the tissues • to protect the damaged tissue from further injury • to protect the newly-formed fibrin bonds from
disruption • to promote collagen fibre growth and realignment • to maintain general levels of cardio-respiratory and
musculoskeletal fitness / activity
![Page 51: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/51.jpg)
Management of medical problems• HYPOTHERMIA• ‘Hypo’ = Below / under ‘Thermia’= heat
- Condition in which a person’s body temperature is sufficiently below normal to cause distress and disorder of normal bodily functions.– Mental deterioration– Loss of coordination– Unconsciousness– Failure of breathing and circulation– Death
![Page 52: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/52.jpg)

![Page 56: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/56.jpg)
Hyperthermia
• Hypertherma = overheating of body• Hyper = ‘ high’, therma = ‘heat’• Body can not effectively regulate excess heat /
elevated temperatures• Temperature > 37.5–39.9 °C• Causes:
– Exposure to excessive heat– Exposure to high humidity– High physical exertion– Dehydration
![Page 57: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/57.jpg)
Hyperthermia• Signs and Symptoms
- Hot, dry skin - Dizziness / Fainting - Nausea / Vomiting - Headaches - Gastrointestinal problems e.g. Diarrhoea - Multi-organ dysfunction
Treatment: - Cool / tepid water immersion - Rehydration - Sponging head, neck, trunk with cold water - Sit in shade
![Page 58: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/58.jpg)
Dehydration
• Fluid Loss exceeds Fluid Intake• Causes:
- Excessive Sweating - insufficient fluid intake - Hot & humid conditions - High intensity exercise
![Page 59: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/59.jpg)
Dehydration
• Consequences:– Increase in perceived effort– Reduced performance– Impaired reaction times, judgement,
concentration and decision-making
• Electrolyte Drinks - Sodium (speeds fluid absorption)- Carbohydrate (provides fuel) - Small amounts frequently (500-800ml/Hr)
![Page 60: Sports conditions,injuries and prevention Kate Logan & Claire Prenter Final year physio students](https://reader036.vdocuments.us/reader036/viewer/2022081504/568149a2550346895db6e3be/html5/thumbnails/60.jpg)
