The rhomboid muscles are two rhombus-shaped muscles located on each side of the upper back. They are often simply called the rhomboids and consist of two functionally similar muscles called the rhomboid minor and rhomboid major. These muscles are responsible for scapular retraction and downward rotation, countering the upward rotation by the trapezius muscle. They are crucial during activities requiring adduction and internal rotation of the shoulder and are essential for movements like rowing or pulling.

The rhomboid muscles are two bilateral muscles located in the upper back
The rhomboid muscles play a crucial role in scapular stability and control. They receive their innervation from the dorsal scapular nerve (C4-C5), a branch of the brachial plexus. This nerve originates from the ventral ramus of the spinal nerve root C5 and courses through the middle scalene muscles. The dorsal scapular nerve provides innervation to both the rhomboid minor and major muscles. The rhomboid muscles also receive arterial blood from three sources: the dorsal scapular artery, its deep branch, and the transverse cervical artery.
The rhomboid minor originates from the nuchal ligament and the spinous processes of the seventh cervical (C7) and first thoracic (T1) vertebrae. It extends obliquely in an inferolateral direction and inserts into the base of the medial end of the spine of the scapula. The rhomboid minor has two layers: dorsal and ventral. The dorsal layer attaches dorsolaterally and inferiorly to the levator scapulae, while the ventral layer inserts inferomedially. At the insertion point of the ventral layer, the fasciae of the rhomboid minor and serratus anterior muscles unite.
The rhomboid major is a quadrangular muscle located inferior to the rhomboid minor. It originates from the spinous processes of the T2-T5 vertebrae and inserts on the medial border of the scapula, just below the rhomboid minor. The rhomboid muscles work synergistically with other periscapular muscles to maintain scapular positioning, which is vital for proper glenohumeral mechanics. They facilitate scapular retraction and downward rotation, countering the upward rotation of the trapezius muscle.

They are comprised of the rhomboid minor and rhomboid major
The rhomboid muscles are comprised of the rhomboid minor and rhomboid major. These muscles are located in the upper back, with the rhomboid major being the larger of the two and situated inferior to the rhomboid minor. The rhomboid minor is a small, cylindrical muscle that consists of two layers: the dorsal and ventral layers. These muscles are innervated by the dorsal scapular nerve, which is crucial for the coordinated action of scapular stability and control. The nerve originates from the ventral ramus of the spinal nerve root C5 and courses through the middle scalene muscles.
The rhomboid muscles are rhombus-shaped and are associated with the scapula. They work together with the serratus anterior, trapezius, and levator scapulae muscles to anchor the scapula and prevent winging. The rhomboids also play a vital role in actions such as pulling and throwing, and they are essential for maintaining proper glenohumeral mechanics. The muscles receive their blood supply from the dorsal scapular artery and the deep branch of the transverse cervical artery.
The rhomboid muscles originate from the spinous processes of the vertebrae and insert on the medial border of the scapula. Specifically, the rhomboid minor originates from the nuchal ligament and spinous processes of the seventh cervical (C7) and first thoracic (T1) vertebrae, while the rhomboid major originates from the spinous processes of the T2-T5 vertebrae. The rhomboid minor inserts into the base of the medial end of the spine of the scapula, with the dorsal layer attaching dorsolateral and inferior to the levator scapulae and the ventral layer inserting inferomedially.
The rhomboid muscles are important for stabilizing the scapula and reinforcing the shoulder. They facilitate scapular retraction and downward rotation, countering the upward rotation of the trapezius muscle. This is particularly important during activities that require adduction and internal rotation of the shoulder, such as rowing. By contracting the rhomboid muscles, the scapula is brought towards the vertebral column, enabling movements that involve pulling.

The rhomboids work with other muscles to anchor the scapula and prevent winging
The rhomboid muscles are two bilateral, superficial muscles located in the upper back. They are called the rhomboid minor and rhomboid major. The rhomboids work together with other muscles to stabilise the scapula and prevent winging.
The rhomboids originate from the C7 to D5 spinous processes and insert into the medial border of the scapula. They are innervated by the dorsal scapular nerve (DSN), a branch of the brachial plexus. When the rhomboids contract, they retract the scapula superomedially and rotate the glenoid cavity, stabilising the scapula in place and reinforcing the shoulder.
Scapular winging is a condition where the medial border of the scapula lifts off the thoracic wall, causing the scapula to appear winged. This can be caused by weakness or paralysis of the rhomboid muscles, which can be secondary to DSN damage or neuropathy. DSN compression is often attributed to the nerve passing through the middle scalene muscle, but it can also be compressed by the proximal part of the medial border when the arm is raised. In such cases, the trapezius muscle can substitute for the rhomboid in scapular adduction movement, preventing winging.
Rhomboid muscle weakness or paralysis can lead to scapular winging, but it is not the only cause. Other muscles, such as the serratus anterior, can also contribute to scapular winging when weak. Accurate diagnosis is important to differentiate between these causes and determine the appropriate treatment.

Rhomboid muscle pain can be caused by osteoarthritis or sports injuries
The rhomboids are two bilateral muscles located in the upper back, comprising the superficial layer of the extrinsic back muscles. They are part of the shoulder girdle and help move the shoulder blade, keeping the shoulder stable. They also enable you to pull back your shoulder blade, lift and rotate it, and help you throw, pull, and reach overhead.
Rhomboid muscle pain can be caused by osteoarthritis, a degenerative bone disease that causes a loss of cartilage. Osteoarthritis causes pain and stiffness in the joints, limiting movement in the shoulder and causing discomfort in the surrounding muscles, including the rhomboids.
Sports injuries can also cause rhomboid muscle pain. Sports that require a lot of throwing or swinging, such as tennis, golf, or rowing, can lead to pain in this area. Activities that involve extending the arms overhead for long periods, such as lifting heavy objects or carrying heavy bags and backpacks, can also cause rhomboid muscle soreness.
To prevent and treat rhomboid muscle pain, it is important to warm up and stretch before and after exercise, maintain good posture, and take breaks from sitting or standing for long periods. Resting the affected area and applying ice can also help with recovery. In some cases, it may be beneficial to consult a physical therapist or physiotherapist for guidance on specific exercises and stretches to relieve pain and improve recovery.

Treatment for rhomboid pain includes warm-up stretches and strengthening exercises
The rhomboids are two bilateral, superficial muscles located in the upper back. They are made up of two functionally similar muscles: rhomboid minor and rhomboid major. These muscles, along with the trapezius, levator scapulae, and latissimus dorsi, form the superficial layer of extrinsic back muscles. The rhomboid muscles are responsible for retracting the scapula superomedially and rotating the glenoid cavity, thus stabilising and reinforcing the shoulder.
Rhomboid muscle pain can be caused by a strain, injury, or tear, and it can also be associated with osteoarthritis, a degenerative bone disease that causes cartilage loss, leading to pain, stiffness, and reduced shoulder movement. Treatment for rhomboid pain typically involves a combination of warm-up stretches, strengthening exercises, and self-massage techniques. Here are some specific methods to alleviate rhomboid muscle pain:
Warm-up Stretches
- Before and after exercising, ensure you warm up and stretch to protect your muscles.
- If you experience muscle soreness after a workout, allow those muscles to rest and focus on stretching a different muscle group.
- If you work at a desk, take frequent breaks to stand up, move around, and stretch.
- Stretch your arms out in front of you and clasp your hands together. Gently reach forward, feeling your shoulder blades stretch away from each other. Gently bend your head forward and hold this position for 15 to 30 seconds. Repeat this stretch 2 to 4 times.
- Place your hands on the back of your head and gently push your head down towards your armpit, holding for 15 to 20 seconds. Aim for 3 repetitions on each side.
- Kneel down with your buttocks touching your heels. Extend one hand for support and place the other hand on the back of your head. Twist your body towards the extended arm, aiming to touch your elbows together. Repeat on the other side, looking up as your elbow goes up. Aim for 10 repetitions on each side.
Strengthening Exercises
Place two fingers at the bottom of your chin and gently tuck your chin in while retracting your head backwards. Use your fingers to keep your chin tucked. Hold this position for 3 to 5 seconds, then relax your neck. Aim for 2 to 3 sets of 10 repetitions.
Self-Massage
Use a tennis ball, foam roller, or self-massager tool to apply gentle pressure and massage the tight spots around your shoulder blade area.
