Buffalo Hump: Causes (Cushing's, Posture) & Physio

What is a Buffalo Hump?

A buffalo hump, known clinically as a dorsocervical fat pad, is an accumulation of fat or thickened soft tissue at the base of the neck, between the shoulder blades. While the term is often used colloquially, in medicine, a hump in this region can be a sign of a hormonal imbalance, a medication side effect, or a chronic postural abnormality.

Identifying the correct cause of the hump is critical for treatment. When the hump is caused by poor postural alignment, a structured buffalo hump causes physiotherapy program can correct the biomechanical issues and significantly reduce its appearance. If it is metabolic, medical intervention is required to address the underlying disease.

Main Causes of a Buffalo Hump

There are three primary reasons why a tissue bulge develops at the cervicothoracic junction (where the neck meets the upper back):

1. Cushing's Syndrome (Hypercortisolism)

Cushing's syndrome is an endocrine disorder characterized by excessive levels of the hormone cortisol in the blood. This can be caused by a tumor on the pituitary or adrenal glands. Cortisol alters the way the body stores fat, driving it away from the limbs and depositing it in the face (moon face), abdomen, and the back of the neck (buffalo hump).

2. Corticosteroid Medications

Prolonged use of oral steroid medications (such as prednisone) for inflammatory conditions like asthma, lupus, or rheumatoid arthritis mimics Cushing's syndrome. This leads to fat redistribution, resulting in a prominent fat pad on the upper back. The hump typically resolves slowly once the steroid dose is reduced under medical supervision.

3. Chronic Poor Posture (Dowager's Hump)

This is the most common cause seen in physical therapy clinics. It is not actually an accumulation of fat, but rather a structural protrusion. Chronic slouching, looking down at phones, and sitting at unergonomic desks lead to Forward Head Posture and Thoracic Kyphosis (an exaggerated outward curve of the spine). To protect the spine from the weight of the head hanging forward, the body thickens the connective tissue and muscles at the base of the neck, creating a firm hump.

Comparing Postural Humps vs. Metabolic Humps

| Feature | Postural Hump (Dowager's Hump) | Metabolic Hump (Dorsocervical Fat Pad) | | :--- | :--- | :--- | | Tissue Composition | Thickened muscle, connective tissue, and bone protrusion. | Soft adipose (fatty) tissue. | | Hump Texture | Firm, hard, and fixed. | Soft, doughy, and movable. | | Primary Cause | Chronic slouching, looking down at devices. | Cushing's syndrome, steroid use, HIV medications. | | Other Symptoms | Neck stiffness, tension headaches, shoulder pain. | Abdominal weight gain, thin skin, purple stretch marks. | | Primary Treatment | Physiotherapy, posture training, thoracic adjustments. | Medical management of cortisol levels, tapering steroids. |

The Role of Physiotherapy for Postural Humps

If your hump is postural, physical therapy is the gold standard for treatment. A physical therapist will evaluate your spinal curvature and design a program based on three pillars:

1. Stretching Tight Structures

Chronic slouching causes the muscles at the front of the body and the top of the neck to tighten, pulling the head forward. Key stretches include:

• Pectoral Stretch: Opening up the chest muscles to allow the shoulders to roll back.
• Suboccipital Release: Stretching the tight muscles at the very base of the skull.

2. Strengthening Weak Extensors

To hold the head and spine in a straight line, the muscles on the back of the body must be strengthened:

• Chin Tucks: Pulling the head backward (making a double chin) to strengthen the deep neck flexors and realign the cervical spine.
• Prone YTWL Exercises: Strengthening the lower trapezius, rhomboids, and thoracic erector spinae muscles to flatten the upper back curve.
• Wall Angels: Re-training the body to keep the spine, head, and shoulders against a flat surface.

3. Ergonomic Assessment

Your therapist will guide you on setting up an ergonomic workstation. This includes raising your computer screen to eye level, adjusting your chair to support your lower back, and taking frequent movement breaks to prevent static muscle tension.

By combining regular clinical chiropractic/manual therapy and home exercises, you can reverse postural humps, eliminate neck pain, and restore healthy spinal alignment.
