Where is the rhomboid muscle
Anatomy, Function & Dysfunction Rhomboid Muscles - Everything You Need To Know - Dr. Nabil Ebraheim
Anatomy function and dysfunction
the rhomboid muscles
oh boy muscles by underneath the
trapezius
the rhomboid muscles connect the scapula
to the vertebrae so it is really helping
to hold the scapula close to the
thoracic wall
during Boyd muscles get the name from
their combined shape having the shape of
rhombus the word rhomboid means a
diamond or a kite shaped object
during Boyd Minor it arises from the
nuchal ligament and the spinous
processes of c7 and t1 vertebrae
it inserts into the medial border of the
scapula above the insertion of the
rhomboid major muscle
don't Boyd major
it arises from the spinous processes
from t2 t3 t4 and t5 vertebrae
insertion it insert into the medial
border which is the vertebral border of
the scapula from the level of the
scapular spine to the inferior angle of
the scapula
it is a diagram that shows the insertion
of the rhomboid minor and major in
relationship to the spine of the scapula
here is a line parallel to the spine of
the scapula and healed the line of the
separation between the two muscles above
this line inserts the rhomboid minor and
below this line inserts the rhomboid
measure
action during Boyd's ADAT or retract the
scapula by bullying the scapula towards
the vertebral column
it works with the levator scapulae to
elevate the medial border of the scapula
it also rotates the sky black downwards
with respect to the glenohumeral joint
the employees participate in proper
movement and the stability of the
scapula which is critical for shoulder
function
nerve supply dorsal scapular nerve c4 c5
you
clinical entities related to the
rhomboid major and minor muscles
brachial plexus injury if the patient
has a brachial plexus injury and an EMG
show evidence of an intact signal in the
serratus anterior muscle which is
supplied by the long classic nerve and
also an intent signal in the rhomboid
muscles which is supplied by the dorsal
scapular nerve this situation indicates
that the lesion of the brachial plexus
is post ganglionic injury which will
have a better prognosis than the
preganglionic injury of the brachial
plexus
definitely the preganglionic injury you
will have a poor prognosis
the preganglionic injury is associated
with Horner's syndrome ptosis miosis
anhidrosis due to disruption of the
sympathetic chain
there will be also medial winging of the
scabbard due to loss of the serratus
anterior and there Boyd muscle function
then failure border of the scapula
will move medially
in the preganglionic injury of the
brachial plexus will be loss of the
muscle function of the levator scapulae
and rhomboid muscles
basically we will examine proximally the
muscles that are innervated root level
motor branches the nerves that are
coming out of the roots
detecting if the brachial plexus injury
is preganglionic or postganglionic
injury is important the normal Palace
final muscle activity called EMG
indicates a post ganglionic injury which
will have good prognosis
another entity that is popular is
rhomboid trigger points muscle pain and
tightness usually the patient complain
about superficial pain between the
shoulder blades patient described it as
an ache or they feel knots
here is a diagram that shows the area
where the patient feels the pain in
between the shoulder blades
the pain is closer to the scheduler than
to the spine
the paint or cares especially at rest
and movement does not influence the pain
the patient also may feel grinding or
snapping or a crunching noise during
movement of the scapula and in this case
in a tool out establish rusick
impingement or it's nabbing a scheduler
other muscle trigger points can be
associated with rhomboid trigger points
such as pectoralis major levator
scapulae and trapezius
so what aggravate the condition of
rhomboid trigger points
painters that holding their arm above
the head for a long time
bad posture like the people that work
habitually in Islam forward round
shoulder position which is a protected
position such as in people that work on
a computer or a desk job or people that
are sewing or reading in this situation
the pectoralis which is antagonistic to
the retraction function of Durham Boyd's
this muscle may become shortened and
overactive and the rhomboids become
stretched trying to counteract the pull
of the pectoralis
avoid aggravating the problem some
people believe it is better to work on
the pectoralis first before you work on
their own voyage
because if you stretch them boys would
type pectoralis muscle this may increase
the weakness and irritation of the
trigger points
so how do you treat rhomboid trigger
points
he gave the patient anti-inflammatory
medication you may try to search the
pectoralis first you may do rhomboid
trigger point release you may treated by
a tennis ball and possible injection of
the trigger points
it may be really hard to tell if the
rhomboids is causing the pain between
the shoulder blades or other muscles
that are inserted around the same area
thank you very much I hope that was
helpful
