We report six cases of a novel syndrome of acute, exertional low back pain in football players, five in college and one in the National Football League. All six are African Americans with sickle cell trait (SCT). The acute low back pain is severe and can be disabling, and the condition can be confused with muscle strain, discogenic pain, stress fracture, or other problems in athletes. Read More

Piriformis syndrome is a rare entity resulting in severe unilateral isolated buttock pain shooting in nature, non discogenic in origin. MR imaging of pelvis plays an important role in such patients to see the normal anatomy of piriformis muscle and its relationship with sciatic nerve. A 35-year-old woman presented with one year history of radiating leg pain with normal MR lumbosacral spine. Read More

Chronic low back pain (CLBP) is one of the main causes of disability in the western world with a huge economic burden to society. As yet, no specific underlying anatomic cause has been identified for CLBP. Imaging often reveals degenerative findings of the disc or facet joints of one or more lumbar motion segments. Read More

Background: Intervertebral disc herniation, spinal stenosis, intervertebral disc degeneration without disc herniation, and post lumbar surgery syndrome are the most common diagnoses of chronic persistent low back and lower extremity symptoms, resulting in significant economic, societal, and health care impact. Epidural injections are one of the most commonly performed interventions in the United States in managing chronic low back pain. However the evidence is highly variable among different techniques utilized - namely interlaminar, caudal, and transforaminal - and for various conditions, namely - intervertebral disc herniation, spinal stenosis, and discogenic pain without disc herniation or radiculitis.

Optimal conservative therapy of discogenic lumbosacral radiculopathy is a matter of debates. Contemporary guidelines recommend measures that predominantly have an influence on nociceptive mechanisms. However the mixed nature of pain in patients with discogenic radiculopathy requires approaches used for treatment of neuropathic pain. Read More

Procedures involving anterior surgical decompression and fusion are being performed with increasing frequency for the treatment of a variety of pathological processes of the spine including trauma, deformity, infection, degenerative disease, failed-back syndrome, discogenic pain, metastases, and primary spinal neoplasms. Because these operations involve anatomy that is often unfamiliar to many neurological and orthopedic surgeons, a significant proportion of the associated complications are not related to the actual decompressive or fusion procedure but instead to the actual exposure itself. To understand the nature of these injuries, a detailed anatomical study and dissection was undertaken in six cadaveric specimens. Read More

Object: Because lumbar magnetic resonance (MR) imaging fails to identify a treatable cause of chronic sciatica in nearly 1 million patients annually, the authors conducted MR neurography and interventional MR imaging in 239 consecutive patients with sciatica in whom standard diagnosis and treatment failed to effect improvement.

Methods: After performing MR neurography and interventional MR imaging, the final rediagnoses included the following: piriformis syndrome (67.8%), distal foraminal nerve root entrapment (6%), ischial tunnel syndrome (4. Read More

The authors describe a case of a 12 years old boy who suffered from pain in the lumbar region, limitation of dynamics in lumbosacral spine with a gradual deterioration of the condition. The patient was afebrile. The pain was getting worse and the classic radiographs did not show at the beginning any pathological changes. Read More

The puncture laser discectomy was conducted in 273 patients with discogenic lumbosacral radiculitis while the conservative therapy inefficacy, pain syndrome in a lumbago stage present and lumboischialgia with absent prominent locomotive disorders and if the intervertebral disc hernia has the size up to 0.6 cm.

Several experimental and clinical studies suggest an important role of the quality and quantity of the material compressing the lumbosacral spinal cord radices in the development of cauda equina syndrome. These facts inspired the author to find out if the repair of neurological functions depends also on these factors. Clinical investigations of 81 persons (30 women and 51 men) were performed at minimum time of two years after the operation of the cauda equina discogenic syndrome. Read More

The radiographic fusion rates, graft behaviour and clinical outcome of 41 patient with simultaneous combined anterior lumbar interbody fusion and posterior arthrodesis with translaminar screws were reviewed independently. In all patients a femoral cortical allograft (FCA) ring filled with autologous iliac crest cancellous bone was used anteriorly to replace the disc and achieve interbody fusion. The follow-up averaged 30. Read More

Percutaneous laser discectomy (PLD) was performed in 273 patients with herniated disc-induced lumbosacral radiculitis. Indications for PLD were based on clinical and neurological findings and results of MR tomography: no benefit from conservative treatment, pain syndrome in the lumbago stage and sciatica not presenting with severe paresis and with herniated intervertebral discs down to 6 mm in size across.

Study of biopsy material obtained from 612 surgical patients with vertebrogenic diseases of spinal radicles at the lumbosacral level and collation of the morphologic findings with the clinical picture of the disease revealed a correlation between the clinical manifestations and the inflammatory process in the vascularized tissues of the vertebral column. The severity of pain was found to depend on the degree of inflammatory changes in the epidural cellular tissue and spinal membranes. The frequency and severity of inflammatory reactions make it possible to consider inflammation, along with compression and ischemia, an important pathogenetic mechanism of the development, progression and course of the discogenic radicular syndrome and to recommend the inclusion of antiinflammatory drugs in multiple modality treatment of the disease as a method of pathogenetic therapy.
