hypolordosis

Hypolordosis is the reduction or flattening of the spine’s normal lordotic curves, most commonly in the cervical or lumbar regions. In a typical standing posture, the cervical spine has a forward curve of roughly 20 to 40 degrees and the lumbar spine about 40 to 60 degrees; hypolordosis describes a curvature shallower than normal.

Causes are varied and may include prolonged poor posture, forward head position, and extended periods of sitting. Muscular imbalances such as tight hip flexors or neck flexors and weak back or abdominal muscles can contribute. Degenerative disc disease, spondylosis, trauma or fractures, obesity, and certain congenital conditions can also lead to hypolordosis. In some cases it is an adaptive response to pain or a fixed deformity.

Symptoms are often related to muscle strain and altered biomechanics. People may experience neck or back pain, stiffness, reduced range of motion, and headaches (in cervical cases). Some individuals report fatigue or radicular symptoms if nerve roots are affected.

Diagnosis involves physical examination and imaging. Standing lateral spine radiographs are used to measure the degree of curvature, while MRI or CT may be obtained to evaluate adjacent soft tissue and bony structures or to assess for underlying pathology.

Treatment focuses on addressing the underlying cause and restoring spinal mechanics. Conservative approaches include physical therapy with postural training, strengthening and flexibility exercises, core stabilization, ergonomic adjustments, and pain management. In selected cases, bracing, injections, or other interventions may be considered. Surgical correction is rare and typically reserved for persistent deformity with neurologic impairment or unresponsive pain.

Prognosis depends on the cause and severity, with many patients improving through rehabilitative therapy, while chronic degenerative or fixed deformities may require ongoing management. See also: flat-back syndrome, hyperlordosis, scoliosis.
