t
33. Thick plate
With round holes
Used in combination with screws in
Diaphysial fractures
AO plates
34. The holes are designed to utilise spherical gliding
principle
Less surgical exposure
Can fit in any position
Screw can be inserted at any angle
Indications >fracture shaft humerus
>Monteggia fracture
>fracture of both radius & ulna
>fracture shaft femur
Dynamic Compression
plate
36. Prevents displacement of fracture
from bending/shearing force
C-Clover leaf plate
Buttress plate
Indications
>fracture of surgical neck of humerus
>Colles fracture
>Condylar fracture of femur
>Condylar fracture of tibia
38. Reconstruction
plateThickness is between DCP & buttress plate
Scallop like notches presents between holes
Can be contoured in 3 planes
Indications >Fracture clavicle
>Supracondylar fracture
>intercondylar fracture
>Fracture acetabullum
39. T - plate
Oblique T plate
Indications
>intercondylar fracture of humerus
>Condylar fracture of tibia
43. They are threaded whole
length
Available in different size
Functions as lag screw,
positional screw
Cortical screws
Indications >fracture of surgical neck of humerus
>fracture shaft humerus
44. Thinner core diameter
Wider & deeper threads for better grip in
“spongy bone”
Fully/Partially threaded
Indications >Fracture of surgical neck of humerus
Cancellous screws
54. Can be used in simple & compound fracture
Can be used in segmental, comminuted, bone
loss etc
For treatment of nonunion
For reconstruction following tumour excision
Low blood loss, low risk of infection
Short operative period
Dynamic- locked at one end
Static- locked at both ends
61. Enders nail
Rush nail
Flexible medullary nail
(condylo cephalic
nail)
Passed from distal to proximal
Fracture fixation is achieved by three
point pressure system
67. Hip implants
Austin Moore pins
Knowles pin
Used for fracture neck femur
Can be used for fracture clavicle
68. Dynamic hip screw
Has lag screw & barrel
Indications
>fracture neck femur
>trochanteric fracture
of femur
>subtrochanteric
fracture
69. Austin Moore prosthesis (Unipolar)
In elderly patients with
fracture neck femur, for
replacing head of femur
Can be removed once the
bone grows
Fenestrations are present
on the stem through which
the bone supposedly grows &
helps in fixation of the
prosthesis
Movement takes place
between head part of
prosthesis & acetabulum
Bone graft
placement
70. Bipolar Prosthesis
Indicated when neck of the femur
is absorbed, like in old fracture of
the femoral neck.
It Is bipolar ,that is movement at
>acetabulum & acetabular
component of prosthesis,
>acetabular component &
head component.
72. Charnley's prosthesis
Into the medullary cavity
neck
Head of femur
Acetabulum cup
Total hip replacement
Indicated in fracture neck femur
73. Smith Peterson
nailCannulated triflanged nail
Prevents axial rotation of the fragments
Cuts only a little bone to give good stability
Indications > fracture neck femur
>Intertrochanteric fracture
78. Staples
Conventional type
U type
To arrest the growth of the epiphysis
Fixation of valgus deformity
For arthrodesis of small joints
79. It is the method of fixing the fracture with the
cluster of pins connected with bars
Provides stable fixation
Force can be applied along any axis
Helps in wound care & reconstructive surgery
87. Ilizarov’s fixation
system
It Is ring fixator
Indicated in limb
lengthening,
nonunion,
deformity
correction,
osteomyelitis,
Provides
distraction force
which will help in
growth of bone
