A
§ Avascular necrosis § Non-union / mal-union § Dislocation § Shortening of leg § Infection § Non-healing of wound § Penetration of metal-ware § Metal-ware loosening § 2° osteoarthritis
20
Q
Classification of hip fracture
A
subcapital /intracapsular fracture
intertrochanteric/extracapsular fracture
subtrochanteric fracture
Slide 14
21
Q
Garden classification system is for what
A
intracapsular fractures
22
Q
Type 1 garden classification fracture
A
Type I fractures have the best outcome. The
bone ends are impacted into one another, which
facilitates vascular re-growth.
23
Q
Type II Garden classification fracture
A
Type II fractures are not impacted and are thus
less stable. However there is minimal
displacement of the bones from the anatomically
normal position, and this is beneficial.
24
Q
Type III Garden classification fracture
A
Type III fractures are complete but there is only partial displacement (<50%).
25
Type IV Garden classification fracture
Type IV fractures are complete with total
displacement (>50%). The two ends of bone are
completely separated.

Physiotherapy management for # NOF
§ Mobilise usually day 1 à mobility ax
§ Often easily fatigued à concentrate on functional activities only
§ Co-ordinate with nursing staff
§ Can generally WBAT, except if fixation stability = fragile or it is a
relatively young patient, (about < 65 yrs ), in which case they are
usually TWB or NWB only
32
Physiotherapy managment for #SOF
§ Usually rodded / nailed
§ Usually mobilise TWB, Day 1. Will be NWB if pin & plate
§ Need to work on knee flexion and quads. Promote regular
independent active work
§ Patient advised to rest with leg in elevation+++ for 10 days post-op.
33
Post op delirium
§ Early detection is key to management
§ Poorly recognized, misdiagnosed as dementia
or depression
§ Generally reversible, but poor prognosis
§ Develops quickly, fluctuates during day
34
Risk factors for post op delirium
dementia, anticholinergic drugs, prev delirium,
| indoor falls, prev stroke, depression, impaired hearing or vision
35
causes of post op delirium
anaemia, CHF, severe hypotension, pulmonary
complications, increase in cortisol levels, UTI, fevers, feeding issues
(Lundstrom, 2004)
polypharmacy, hypoglycamia, hypoxaemia, metabolic encephalopathy
36
early aims of #NOF treatment
| literature supports what
- early mobilisation (Day 1-2 post-op)
- encourage ambulation WBAT/TWB
- encourage maximal functional
independence
- ensure adequate pain relief
- provide appropriate walking aid/s
- ensure patient safety at all times
- discourage prolonged bed rest, but
ensure adequate rest periods
37
Function outcomes - physio role
```
§ Level of assistance required for
lying ↔ sitting ↔ standing
§ Balance
§ Willingness to weight-bear
through # leg
§ Distance walked
§ Frame → crutches
§ ↑ and ↓ steps / ramp
```
38
Physio intervention - physio role
```
Early mobilization
§ Consider analgesia prior to
mobilizing
§ Provide walking aids
§ Mobility status, ward function
§ Assess transfers
§ Falls prevention program
§ Exercises
§ Chest Physiotherapy
§ Circulation exercises
§ Hip precautions (if indicated)
```
39
EBP guidelines
Daily evaluation by geriatricians and orthopaedic
specialists
§ Early mobilisation
§ Transfer to a rehabilitation unit or home by Day 3
post-op.
§ Dedicated team with orthopaedic and geriatric
leadership has lead to improved efficiency and quality
of care for patients
§ Exercises: bridging (for Hemi), IRQ, hip and knee
flexion, knee abduction

general fracture management guidelines for #tibial plateua /supracondylar knee #
* usually ORIF’d with plates and screws +/- bone graft, or nailed
* usually to be fitted with IROM brace with open range 0°- 90°
* usually mobilise NWB, Day 1
* need to work on knee ROM and quads. Promote regular
independent active work
* patient advised to rest with leg in elevation+++ for 10 days post-op.
41
general fracture guidelines # patella and ORIF with tension band wiring
* sometimes go into an IROM brace locked in extension or limited
ROM
* sometimes go into knee brace which is to be removed for showering
& gentle flexion exercises
* usually mobilise WBAT, Day1
* provide with lifting strap for self-assistance of injured leg
42
General fracture guidelines #Tibia/fibula (shafts)
* usually rodded / nailed → mobilise TWB, Day 1
* also can be ORIFd with plate and screws or fixed with an
external fixateur → mobilise NWB
* need to work on knee flexion, dorsiflexion and quads.
Promote regular independent active work (SQ, IRQ, SLR, hip
+knee flexion, hip abd/add)
* will often be given a BKPOP or aircast walker for 2 weeks for
comfort and to avoid foot-drop
* patient advised to rest with leg in elevation+++ for 10 days
post-op.
43
ankle general fracture guidelines
* usually ORIFd with plates and screws

swelling is an issue)
* patient advised to rest with leg in elevation+++ for 10 days
post-op.

44
humerus general fracture guidelines
* usually mobilise day 1
* Op arm rests in sling
* Wrist, hand, elbow, grip strengthening op
arm, PROM/AAROM shoulder flexion/
abduction, pendulum ex as per surgeon
* D/C Day 1/2/3 if mobile and safe home
environment
45
pelvis (pubic rami) general fracture guidelines
* usually mobilise WBAT as soon as patient is
able to move independently across the bed
* if more than one ramus is #d, progression of
mobility is usually slower due to pain
46
When do you suspect a spinal injury
* Think about mechanism of injury → fall/heavy load/bending/
impact/RTA
* Suspect in all unconscious patients → they can’t tell you if they
have any spinal pain
* Presence of any neurological red flags
* Any spine pain or tenderness → however if no pain you can’t
necessarily rule out injury
* Don’t forget other injuries – beware the “distracting injury”
1) Immobilise on rigid board – start spinal rules
2) Apply rigid collar
Protection is priority, Detection is secondary
47
Canadian C spine rules
* Highly sensitive, reliable
* Alert, stable, recent trauma - ?X-Ray
* Not applicable in unstable patient, acute paralysis,
known vertebral disease, prev CSp surgery,
paediatrics, pregnant

Why are fractures missed?
• Poor history and examination
• Not linking radiology with clinical findings
• Failure to examine all views
• Poor methodical approach
• Failure to order special views
“One view is one view too few – Geoff Connor, 2016”
• Failure to identify need for a comparison view
• Failure to get a second opinion

reading an MSK x-ray - guidelines
1. Use a systematic approach
2. Check patients name, date of X-Ray, side of body (should be a marker)
3. Consider clinical information why do you require an X-Ray?
4. Look at all images available
5. Bone & Joint alignment
6. Bone cortex and cortical outline
7. Joint spacing
8. Soft tissue structures

fracture causes
• Traumatic # -caused by abnormal trauma e.g. fall,
sport, car accident
• Pathological # - fracture in bone weakened by disease
• Periprosthetic # - fracture at point of mechanical
weakness of an implant
• Avulsion # - tendon or ligament remains intact but
pulls off bone fragment
91
classification of fractures
```
• Classified by type of fracture, relationship to
skin, extent, location
• Some fractures may be classified by specific
name
Relationship to the Environment
Open vs. Closed
Extent
Complete vs. Incomplete
Site/Location
Intra-articular, location of bone
Epiphyseal/growth plate (Salter-Harris)
Location along long bone (head, base,
shaft, neck)
```
92
classification of fractures continued
```
Relationship of the
Fragments
Displaced vs. Undisplaced
Involvement of dislocation
Angulated, impacted,
compression
• Configuration
```
93
Fracture classification : location
– shaft (proximal, middle, distal) of long bones
– medial, lateral (e.g. in ankle)
– head, base (e.g. in phalanges)
– intra-articular / extra-articular (e.g. tibial plateau)
– epiphyseal (proximal, distal)
– subcapital / intertrocanteric / subtrocanteric (e.g. in hip)
– supracondylar / intercondylar (e.g. in knee or elbow)
– periprosthetic (joint replacements or previous ORIF)
94
bone alignment
• Crucial in determining management of
fracture
• Loss of alignment can be accompanied by
change in bone length, angulation or rotation
95
Scaphoid fracture
```
• Most common type of carpal bone fracture
• Pain at base of thumb – ASB tenderness
• FOOSH
• Men 20-30yr, adolescents/
young adults
• Needs specific scaphoid view
• 10% distal, 70-80% waist, 20%
proximal pole
```
96
colles fracture = distal radius
* Transverse + partially comminuted fracture of distal radius
* Distal component dorsally displaced and angulated
* Associate transverse fracture of Ulna styloid
* Also called a “dinner fork” or “bayonet” due to shape of forearm
* Often from FOOSH
* Common in osteoporotic bones, middle age elderly
97
Weber A ankle fracture
```
• Fracture of the lateral malleolus
distal to the syndesmosis
• Below level of ankle joint/mortise
• Tib/fib syndesmosis intact
• Deltoid lig intact
• Medial malleolus often fractured
• Usually stable but can require ORIF
occasionally
```
98
Weber B ankle fracture
```
