Osteoporotic Vertebral Compression Fractures with Kyphotic Deformity

Osteoporotic Vertebral Compression Fractures (OVCF) represent the most frequent fragility fractures in the aging population, impacting millions of older adults, particularly postmenopausal women. Typically occurring in the mid-thoracic spine and thoracolumbar junction (T7 through L2), these fractures result from minimal mechanical trauma, such as coughing, bending forward, or missing a small step. Because the failure predominantly collapses the weaker anterior trabecular bone while the posterior elements remain intact, the vertebral body collapses into a wedge shape. Multiple sequential wedge fractures produce progressive, rigid thoracic hyperkyphosis, clinically recognized as a Dowager hump. This structural collapse drives marked positive sagittal imbalance, chronic pain, restrictive pulmonary decline, and impaired digestive function.

Postmenopausal Vulnerability, Low Milk Intake, and Domestic Hazards in India

In India, the burden of postmenopausal osteoporosis is exceptionally high, compounded by widespread vitamin D3 deficiency, low dietary calcium intake, and limited access to routine dual-energy X-ray absorptiometry (DEXA) bone scans in semi-urban areas. Older Indian women frequently sustain compression fractures during routine domestic activities: lifting a bucket of wash water, picking up a gas cylinder, or simply bending forward to sweep under furniture with a traditional short broom (jhadu). Following a fracture, family members often instruct the senior to remain strictly bedridden on a soft mattress, which rapidly accelerates bone mineral loss and muscle wasting. Physiotherapists guide Indian families to eliminate forward-bending chores, provide long-handled cleaning tools, and initiate safe, upright mobility to protect fragile bones.

Trabecular Microfracture Mechanics, Wedge Collapse, and Kyphotic Cascade

The pathophysiology of osteoporotic compression fractures is governed by structural biomechanics. With advancing age and estrogen depletion, horizontal bone trabeculae undergo progressive resorption and thinning, leaving vertical trabeculae unsupported and vulnerable to buckling under normal axial compressive loads. When a wedge fracture occurs, the loss of anterior vertebral height tilts the overlying spinal segments forward, shifting the body center of gravity anteriorly. This forward shift drastically increases the flexion bending moment acting on adjacent osteoporotic vertebrae, creating a self-propagating biomechanical cascade: one compression fracture triples the risk of sustaining a second fracture within 12 months. As kyphosis worsens, the rib cage is driven downward toward the iliac crests, compressing the abdominal cavity and restricting diaphragm descent.

Flexion Contraindications, Prone Thoracic Extension, and Postural Bracing

The primary golden rule of physiotherapy for osteoporotic compression fractures is the strict contraindication of spinal flexion exercises: standard abdominal crunches, toe-touching, and forward bending must be completely eliminated, as forward flexion increases compressive forces on the anterior vertebral bodies by over 300 percent, precipitating new fractures. Instead, rehabilitation focuses on gentle, active thoracic extension exercises performed in prone or supported seated positions to strengthen the posterior paraspinal tension band. Patients with acute, painful fractures are often fitted with a semi-rigid thoracolumbosacral orthosis (such as a Spinomed or Jewett hyperextension brace) to offload the anterior column during standing. Gait re-education with a wheeled rollator restores upright balance and prevents catastrophic falls.
