112 Possible Causes for Loss of Lumbar Lordosis

  • Osteoporosis

    This is followed by a loss of lumbar lordosis.[] (dowager hump) Subsequent loss of lumbar lordosis A decrease in height of 2-3 cm after each vertebral compression fracture and progressive kyphosis Patients with hip fractures[] […] patients with increased risk of fracture. [92] Signs of fracture Patients with vertebral compression fractures may demonstrate a thoracic kyphosis with an exaggerated cervical lordosis[]

  • Ankylosing Spondylitis

    Chronic spondylitis leads to loss of lumbar lordosis and increased kyphosis which may cause difficulty in breathing which is a serious complication of this disorder.[] In late stages, the patient has accentuated kyphosis, loss of lumbar lordosis, and fixed bent-forward posturing, with compromised pulmonary function and inability to lie flat[] In the advanced stages, patients develop loss of lumbar lordosis, buttock atrophy, and an exaggerated thoracic kyphosis with a stooped forward neck sometimes referred to as[]

  • Ochronosis with Alkaptonuria

    In the thoracolumbar spine, one may see osteopenia, loss of lumbar lordosis, multilevel calcification of the annulus fibrosus, vacuum phenomenon, and progressive narrowing[] Radiological examination of spine showed loss of lumbar lordosis, reduction in all disc spaces, and fusion of vertebral bodies with dense calcification of all intervertebral[] […] spine, fusion of vertebral bodies in the upper lumbar spine, osteophyte and bone bridge formation, and loss of lumbar lordosis (Figure 3 ).[]

  • Spinal Stenosis

    Other positive findings include loss of lumbar lordosis and forward-flexed gait. [7] Fig. 3: Achilles tendon reflexes [2] Fig. 4: Lumbar extension loading test [3] Fig. 5:[] Nevertheless, review of the literature suggests diminished lumbar extension appears most consistently, varies less, and constitutes the most significant finding in LSS.[]

  • Vertebral Osteomyelitis

    , and a loss of lumbar lordosis.[] Article continues below Lumbar infections may also present with pain when standing, irritation of muscles such as the psoas muscle (hip flexor) and hamstring (knee flexor)[]

  • Kyphosis

    Lumbar degenerative kyphosis (LDK) is characterized by sagittal imbalance resulting from degenerative loss of lumbar lordosis.[] Correction loss in global kyphosis (GK) and lumbar lordosis (LL) of the LSI group was slightly higher than that of SSI group.[] When the vertebrae in the lumbar spine are fused together, this lordosis curve may be lost, leaving the patient with a "flat-back" deformity.[]

  • Scoliosis

    BACKGROUND Loss of lumbar lordosis (LL) is closely related to clinical symptoms and operative complications, however, few studies have identified its predictors.[] Others may lean forward because of loss of their natural curve (lordosis, sway back) in their lumbar spine (low back).[] […] of lumbar lordosis rare now that segmental instrumentation addresses sagittal plane deformities decreased incidence with rod contouring in the sagittal plane and compression[]

  • Scheuermann's Disease

    […] adulthood: Loss of lumbar lordosis correlates well with the incidence of chronic low back pain in adulthood [ 15 , 16 ].[] There was spontaneous reduction in lumbar lordosis of varying degrees.[] Sedentary lifestyle contributes to loss of lumbar lordosis as well as scoliosis and thoracolumbar or lumbar kyphosis [ 17 ].[]

  • Kyphoscoliosis

    Figure 6 Most importantly, the lateral clinical photo reveals loss of lumbar lordosis, loss of the normal buttock contour, and need to bend the knees in order to maintain[] Average blood loss was 1090 mL (range, 700-2900 mL).Mean preoperative lumbar lordosis improved from -3 to 42 at the final follow-up, and sagittal balance improved from 12[] Extent of pelvic retroversion, in an attempt to compensate for loss of lumbar lordosis, can be seen on the PA view of the pelvis (champagne glass pelvis—see below in Figure[]

  • Straight Back Syndrome

    It is a postural disorder, primarily caused by loss of normal lumbar lordosis.[] Flat back syndrome (also known as flatback or flat-back syndrome refers to the loss of normal lumbar lordosis.[] The C7 plumb line migrates more anteriorly with aging, mostly due to loss of lumbar lordosis related to disc degeneration.[]
