To pronounce “coccyx,” start by saying “KAWK” for the first syllable. Then, for the second syllable, say “siks” with a short “i” sound. So, the full pronunciation is “KAWK-siks.” Remember to emphasize the first syllable slightly and pronounce the “s” sound in “siks” with a soft “s” sound.

Overview of the Coccyx and Tailbone
Nestled at the base of the spine, the coccyx, commonly known as the tailbone, is a triangular bone composed of several fused vertebrae. It serves as a pivotal point for muscle attachments and provides structural support to the pelvic region.
The coccyx is located inferior to the sacrum, the bone that forms the posterior portion of the pelvis. It consists of three to five individual bones, which gradually diminish in size from top to bottom. These vertebrae are fused together, forming a slightly curved structure.
The coccyx plays a role in weight distribution during sitting and provides stability to the pelvic floor muscles, which are responsible for supporting the bladder, rectum, and other pelvic organs. However, due to its position at the end of the spine, it can be susceptible to injury or pain.
Related Structures and Their Functions
The coccyx, often referred to as the tailbone, is not just an isolated structure; it interacts with several other anatomical components to form a complex network. This intricate interplay influences the coccyx’s function and the overall health of the pelvic region.
Sacrococcygeal Joint
The sacrum, the lowermost segment of the spine, connects to the coccyx through a joint called the sacrococcygeal joint. This joint provides stability to the lower back and pelvis, allowing for weight distribution and shock absorption during movement.
Lumbosacral Plexus
The lumbosacral plexus, a network of nerves originating from the lower spine, plays a crucial role in nerve supply to the coccygeal region. These nerves transmit sensory information from the coccyx to the brain and control motor functions of the surrounding muscles.
Pudendal Nerve
The pudendal nerve is a significant nerve that passes near the coccyx. It supplies sensation to the skin around the anus and genitals. Compression or irritation of the pudendal nerve can lead to coccydynia, a condition characterized by coccyx pain.
Vertebral Column
The coccyx forms the terminal end of the vertebral column, also known as the spinal column. The vertebral column provides structural support to the body, protects the spinal cord, and facilitates movement.
Sacrum
The sacrum, a triangular bone located above the coccyx, supports and stabilizes the lower spine. It also forms part of the pelvic ring, which bears the weight of the upper body and transmits forces during movement.
Filum Terminale
The filum terminale is a thin, fibrous cord that extends from the end of the spinal cord to the coccyx. It provides structural support to the spinal cord and assists in maintaining cerebrospinal fluid circulation.
Levator Ani Muscle
The levator ani muscle forms part of the pelvic floor muscles that support the pelvic organs. It originates from the pubic bone and inserts into the coccyx, contributing to pelvic floor stability and continence.
Gluteus Maximus Muscle
The gluteus maximus muscle, the largest muscle in the buttocks, plays a role in extending the hip joint. It also attaches to the coccyx, providing support and participating in coccygeal movement.
Medical Management of Coccygeal Issues
If you’re experiencing pain or discomfort in your coccyx or tailbone, seeking proper medical attention is crucial. Various treatment options are available to alleviate your symptoms and restore your well-being.
Physical Therapy for Coccygeal Pain Relief
Physical therapy plays a significant role in managing coccygeal pain. Specialized therapists can guide you through targeted exercises that strengthen the muscles surrounding your coccyx, improving posture, and reducing pressure on the affected area. Additionally, they may employ techniques such as massage, heat therapy, and ultrasound to alleviate pain and promote healing.
Injections for Coccygeal Inflammation
In certain cases, your doctor may recommend injections to reduce inflammation and provide immediate pain relief. Steroid injections are commonly used to target the sacrococcygeal joint, effectively reducing swelling and easing discomfort.
Orthopedics for Coccygeal Diagnosis and Treatment
Orthopedic specialists are experts in diagnosing and treating musculoskeletal disorders, including coccygeal issues. They will conduct a thorough physical examination, review your medical history, and possibly order imaging tests to determine the underlying cause of your pain. Based on their findings, they will recommend an appropriate treatment plan, which may include physical therapy, injections, or, in some cases, surgical intervention.
Neurosurgery for Complex Coccygeal Cases
While most coccygeal issues can be managed conservatively, complex cases may require the expertise of a neurosurgeon. This specialized field deals with surgical interventions involving the nervous system, including the spine and spinal cord. If your coccygeal pain is caused by a neurological condition, such as a nerve entrapment or spinal cord injury, neurosurgery may be necessary to address the underlying problem.
Physical Medicine and Rehabilitation for Holistic Recovery
Physical medicine and rehabilitation (PM&R) specialists take a comprehensive approach to treating coccygeal issues. They work closely with patients to develop individualized treatment plans that not only address the physical symptoms but also focus on restoring overall function and well-being. PM&R may include a combination of physical therapy, medication management, assistive devices, and lifestyle modifications to help you manage your pain and improve your quality of life.
