00:00:21
and
00:00:25
concerning the posterior face of the cost
00:00:28
from an anatomical point of view that we will be
00:00:29
able to isolate three
00:00:31
essential elements firstly the
00:00:34
cranial Holly fossa which is
00:00:36
essentially occupied by Greece
00:00:38
secondly the insertion of the
00:00:42
triceps brachii tendon which comes to insert itself on
00:00:46
the water the skulls and finally the
00:00:50
lunar nairu this is rumor in fact comes
00:00:53
from the arm where it will pass into the scepter
00:00:57
intervened what the air then under the arch
00:01:00
this earth thing it will occupy the
00:01:03
ulnar canal this occupation is done between
00:01:06
the peaks we deal medial and the water the
00:01:08
skulls and it will come from this
00:01:14
urinary canal to pass between the two
00:01:17
muscular bundles of the flexor an
00:01:19
era of the carpus
00:01:20
[Music]
00:01:26
so we will approach the posterior compartment
00:01:28
of the elbow which is probably the
00:01:30
easiest compartment to understand in ultrasound
00:01:32
although it is not devoid
00:01:33
of interest since we will find
00:01:35
pathologies of tendon, nerve,
00:01:39
joint or soft parts so
00:01:42
to analyze this posterior compartment the
00:01:44
patient the patient will be positioned
00:01:46
three quarters or even water to
00:01:48
the serious examiner to make him place
00:01:51
the palm of the hand on the
00:01:54
examination table thus bending the cost of
00:01:57
[Music]
00:02:02
the first cut made an
00:02:05
axial cut which is a little general since we
00:02:07
will be able to
00:02:09
visualize on this section all
00:02:12
the elements that we will study
00:02:14
later the derudder
00:02:19
interposed between the epic on deale and the
00:02:24
skulls the triceps and in depth the
00:02:30
ole cranial dimple
00:02:32
[Music]
00:02:37
under the triceps brachii we will be able to
00:02:41
find the fossa and cranial ole which
00:02:44
is occupied mainly by
00:02:46
greece which appears hyper ecogene it is
00:02:49
interesting to possibly see a
00:02:51
mobilization of this cranial ole fat
00:02:54
by an effusion which
00:02:56
could mean a pathology either
00:02:58
joint or a fracture at the cult
00:03:02
level of the bony surfaces of the
00:03:06
posterior face of the blow
00:03:07
[Music]
00:03:11
we can now study the tendon of the
00:03:14
triceps brachii in sagittal section we will
00:03:18
sometimes opt for a hypo ecogenic aspect of its
00:03:21
insertion on the skull bed linked
00:03:23
only to isotropic dan artifacts
00:03:27
it will be enough to switch a little the angle
00:03:30
of attack of the ultrasound beam to
00:03:33
find a morphology and an eco
00:03:37
engineering site is normal to tense this
00:03:39
tendon appears hilar fiber it is in
00:03:43
fact the interposition of
00:03:46
tendon layers and fatty layer which
00:03:50
gives it this appearance a little laminated
00:03:52
if we look at the theses of this tendon
00:03:56
in axial section therefore made 90 degrees with
00:04:00
the probe we will be able to
00:04:04
highlight a discreet aspect
00:04:08
fascicles and of this
00:04:11
distal end of the triceps tendon we
00:04:15
should not confuse these digitas ion
00:04:18
intra tendon with possible
00:04:20
partial lesions
00:04:23
[Music]
00:04:28
the analysis of an era an era is carried out
00:04:31
by an axial cut at the level of this
00:04:33
fossa is at the cranial bed it is
00:04:36
interposed between the epic on deal lots the
00:04:38
skulls and an anatomical report narrow
00:04:40
with the medial head of the triceps brachii
00:04:44
by the elevator technique it can be
00:04:47
followed at the level of the arm
00:04:51
up to the inter muscular septum bones
00:04:58
it can be understood but at this level 6
00:05:01
to 8 cm above the water the skulls by
00:05:05
a fibrous arch after the arcades of
00:05:08
Strueth hours
00:05:10
we can also
00:05:13
analyze it and in sagittal section
00:05:18
here we will be able to measure its
00:05:23
thickness
00:05:24
in axial section we will retain a
00:05:31
surface standard of this nerve an era around
00:05:34
8 square millimeters at the part
00:05:37
distally we can follow this nerve an area
00:05:41
just at the level
00:05:47
of the muscular compartment with the
00:05:50
flexor carpal nerves and the
00:05:54
flexor profundus 4 and 5
00:05:58
[Music]
00:06:03
on these cross sections comparison
00:06:06
of the two tunnels an era we see that the
00:06:10
nerve an area right to
00:06:14
ultrasound signs of suffering it is
00:06:15
swollen and this section surface and
00:06:18
largely increased compared to the
00:06:20
contralateral nerves on the sagittal section we
00:06:23
find this thickening with a
00:06:26
loss of the dune air fascicle aspect
00:06:28
and upstream of the tunnel an area the
00:06:33
ultrasound aspect of this nerve becomes
00:06:35
normal again so here the case of a rupture
00:06:39
of the tendon
00:06:41
precipitates halle which is a
00:06:43
relatively rare lesion which occurs in
00:06:45
high-level athletes in
00:06:48
movements called by force extension and
00:06:51
you see the hiatus at the insertion of the
00:06:55
tendon tri so vital and the area which is
00:06:59
occupied by a hematoma
00:07:02
I present to you the case of a
00:07:04
hydromassage without compression we see
00:07:07
that league roma manifests itself by a
00:07:09
collection year cogen in which
00:07:12
float elements of
00:07:14
fatty type hyperic to the genes if we
00:07:17
compresses the posterior area of ​​the elbow the
00:07:21
compression by the probe will expel the
00:07:23
liquid and the cut becomes again we can
00:07:25
say sub normal you have seen that
00:07:28
the analysis is quite easy we can
00:07:30
essentially see the triceps tendon the
00:07:33
ulnar nerve and the milk fossa
00:07:35
cranial in the salt of the posteriors the
00:07:38
patient's position is also
00:07:41
easy to restore and I thank our
00:07:45
mannequin for the whole day to you
00:07:48
the probe
