A review of 14,296 unselected bone scans identified 889 scans showing absent or faint renal uptake. The majority of cases were associated with renal insufficiency (816/889; 91.8%), while widespread metastatic bone disease was the most common cause in a group of patients without renal disease (53/889; 6.0%). Of the 140 patients with prostate cancer, 108 (77.1%) had evidence of bone metastasis, 19 of whom (17.6%) revealed absent or faint renal uptake, demonstrating that poor renal uptake is more frequently associated with prostate cancer than with any other malignancy. Of note was that 162 out of 328 (49.4%) patients with stomach cancer at varying stages showed evidence of bone metastasis, and 14 of them (8.6%) showed poor renal images on bone scan. Interestingly, ankylosing spondylitis and rheumatoid arthritis were occasional causes of lack of renal activity (4 and 3 cases, respectively). A case of adult-form osteopetrosis, showing strikingly increased uptake mainly in the long bones with markedly diminished renal uptake, was also included in this study. Of the 53 bone scans with metastatic disease showing poor renal uptake, 44 (83.0%) revealed evidence of diffuse or multiple metastases in both spine and ribs, while 49 (92.5%) showed malignant involvement in three or more regions and 35 (66.0%) in four or more regions, suggesting widespread bone involvement in most cases.

Deep bone biopsies were performed in 58 patients over the last 2 years, in a radiology department in Tours, France, under television screen control. Data obtained included pathologic, cytologic and bacteriologic features in the 60 biopsies conducted, localization being the spine in 52 cases (12 dorsal, 36 lumbar, 4 sacroiliac) and the pelvis 8 times. Etiology was a tumoral process in 15 cases (14 metastases and 1 reticulosarcoma), 7 infectious processes including 2 cases of tuberculosis, 26 cases of decalcifying degenerative osteopathies, 1 Paget's disease, 1 ankylosing spondylitis and 1 bone infarct. Biopsy was unsuccessful in 9 cases, the success rate being an overall 85%. Complications were not observed. Conducted under local anesthesia, deep bone biopsy provides a rapid diagnosis and allows a shortened hospital stay. Surgery is generally avoided and appropriate treatment instituted more rapidly.

Radiologic examination of 43 patients revealed 47 lesions of a type which we have termed hemispherical spondylosclerosis (HSS). This term describes and includes the following essential and possible radiologic findings of the disease: 1) Hemispherical (or "dome-" or "helmet-shaped") sclerosis of the vertebra above the intervertebral disk. Thus it is a supradiscal HSS. 2) One or more small erosions of the inferior end plate of the vertebra involved. 3) Periosteal apposition on the anterior border of the vertebra along the length of the sclerosis. 4) New bone formation on the inferior end plate. 5) Anterior vertebral osteophytes. 6) Narrowing of the disk space below the affected vertebra. HSS occurs not only as a sequel of degenerative disk disease, but also in bacterial (tuberculous and non-tuberculous) spondylitis, ankylosing spondylitis, osteoid osteoma, and metastases of neoplasms. The differential diagnosis between inflammatory and noninflammatory pathogenesis and etiology of HSS is described. The characteristic shape of HSS, its sites of predilection (14 greater than L5 greater than L3), and the preponderance of female sufferers from this painful condition are due to factors which, as yet, remain unknown.

Bracing of the cervical spine in patients with rheumatoid arthritis, ankylosing spondylitis and instability due to metastases poses special problems. Because of asymmetry, a tender bony or cutaneous swelling or tender skin, difficulties arise in fitting a mass-produced brace. In order to overcome these difficulties a carefully moulded made-to-measure halo-shoulder brace and also a mandibular-shoulder brace were developed. The halo-shoulder brace (a halo connected with 4 rods to a shoulder girdle) provides an effective means of postoperatively controlling the unstable cervical spine until the graft unites. The brace is well tolerated by the patient and facilitates early postoperative mobility. The mandibular-shoulder brace (a similar shoulder girdle with a mandibular and an occipital part), also well tolerated by the patient, is used after the halo-shoulder brace during consolidation of the graft and also to support the neck in patients who for other reasons require a collar but who cannot tolerate a normal readymade appliance. The manufacture of the braces, their effectiveness and a series of 13 patients are described.

The symptom of back pain may be the result of many different pathologies. As such, patients with back pain require careful assessment to determine whether the cause is from the spine or other systems. For acute mechanical back pain, treatment is often symptomatic. Symptomatic treatment may include analgesics, anti-inflammatories and/or muscle relaxants. Patients may also need hypnotics in the short term to help them sleep at night. However, drug therapy should be reduced and stopped as soon as possible. Furthermore, too much bedrest may be counterproductive. Paracetamol (acetaminophen) is the standard treatment for transient back pain. More severe pain may require the addition of an opioid, such as codeine or dextropropoxyphene. Morphine and pethidine (meperidine) may be necessary in patients with back pain due to neoplastic disease or osteoporotic fracture. However, the opioid analgesics are associated with dependence, tolerance and adverse effects. Nonsteroidal anti-inflammatory drugs (NSAIDs) have analgesic efficacy comparable with paracetamol. Individual patients respond differently to different NSAIDs, and several agents may have to be tried. Long term therapy with NSAIDs is necessary in diseases with an inflammatory component such as ankylosing spondylitis. Calcitonin reduces bone resorption and bone blood flow, and has been suggested to have central analgesic effects. As such, it has been used successfully in patients with Paget's disease, osteolytic bone disease and osteoporosis. Bisphosphonates also inhibit osteoclastic bone resorption and may be useful in Paget's disease, osteolytic metastases and osteoporotic fractures. Other drugs which may be useful in relieving back pain associated with specific circumstances include the tricyclic antidepressants, anxiolytics, antiepileptic agents, corticosteroids, colchicine and chymopapain.

Samarium-153-EDTMP is an effective agent for palliation of widespread skeletal metastases because it concentrates in bone metastases which have an osteoblastic component. Similar concentration in areas of osteoblastic activity in ankylosing spondylitis, Paget's disease and rheumatoid arthritis suggests a possible new treatment approach. Three patients with ankylosing spondylitis, one patient with Paget's disease and one patient with rheumatoid arthritis were treated with 153Sm-EDTMP. Objective and subjective improvement was noted, especially in ankylosing spondylitis patients. Samarium-153-EDTMP has disease-modifying potential in ankylosing spondylitis and Paget's disease and has palliative value in resistant rheumatoid arthritis. Further trials to determine optimal dose, treatment scheduling, long-term disease-modifying potential and toxicity are needed.

The majority of cases of spinal canal compromise are caused by common pathologic conditions, including degenerative spondylosis, infection, trauma, and metastatic disease. However, there are other causes of spinal canal compromise that, though unusual, may be seen in everyday practice. Congenital abnormalities of the spine that may produce spinal canal compromise include the os odontoideum, hemivertebra, diastematomyelia, and achondroplasia. Arthritides and enthesopathies such as rheumatoid arthritis, ankylosing spondylitis, synovial cysts of the facet joint, calcium pyrophosphate dihydrate deposition or hydroxyapatite deposition, and ossification of the posterior longitudinal ligament or ligamentum flavum may lead to narrowing of the spinal canal. Primary spinal tumors and tumorlike lesions such as hemangioma, aneurysmal bone cysts, osteochondroma, and osteoblastoma may also cause spinal canal stenosis. Finally, Paget disease of bone may compromise the spinal cord. Radiologists should be aware of these unusual musculoskeletal causes of spinal canal compromise and their radiologic and clinical features.

The sacrum is a structure that is imaged by both general and subspecialty radiologists. A wide variety of disease processes can involve the sacrum either focally or as part of a systemic process. Plain radiographs, although limited in evaluation of the sacrum, should be carefully examined when abnormalities of the sacrum are suspected. Cross-sectional imaging, particularly computed tomography and magnetic resonance (MR) imaging, plays a crucial role in identification, localization, and characterization of sacral lesions. Congenital lesions of the sacrum, including sacral agenesis and meningocele, are optimally imaged with MR. The most common sacral neoplasm is metastatic disease. Primary neoplasms of the sacrum, which include giant cell tumor, chordoma, and teratoma, are infrequent. Infection of the sacrum or sacroiliac joint is most often due to contiguous spread from a suppurative focus. A wide variety of arthritic disorders such as ankylosing spondylitis and osteoarthritis can involve the sacroiliac joints as part of a localized or systemic process. Sacral fractures related to acute trauma or repetitive stress are difficult to diagnose and treat. Knowledge of these abnormalities and familiarity with the imaging of these processes will allow radiologists of all subspecialties to contribute to the diagnosis and management of sacral disorders.

We explored the effect of intravenous infusions of a bisphosphonate, pamidronate, in the management of chronic mechanical spinal pain, a worldwide public health problem in terms of lost workdays, medical treatment costs, and suffering. Bisphosphonates have an anti-nociceptive effect in animals. In humans, intravenous pamidronate relieves numerous painful conditions, including metastatic bone pain, ankylosing spondylitis, rheumatoid arthritis, and complex regional pain syndrome. We reviewed the charts of 25 patients who had experienced disabling spinal pain for several years, and whom we treated with intravenous pamidronate. None had a history of osteoporotic vertebral fractures or metastatic disease. Pain rating scores decreased in 91% of patients: on a 0-10 numeric rating scale, the mean pain change was -3.6 points and mean percentage change was -41% (P<0.0001). There was no increase in opioid or nonopioid analgesic medications associated with pain relief. The apparent analgesic effect of pamidronate for chronic mechanical spinal pain needs to be confirmed with placebo-controlled trials.

Osteitis Condensans Ilii (OCI) is a benign cause of axial low back pain. Although no clear etiology has been identified, the prevailing theory is that mechanical strain affects the auricular portion of the ilium and causes premature arthritis. The location of the sclerosis has been traditionally confined to the ilium and may give the false impression of sacro-iliac joint involvement. Clinicians must be guided by history, radiographic findings, and laboratory studies in differentiating OCI with other disorders; furthermore additional causes of low back pain including metastatic disease and ankylosing spondylitis must be ruled out. Treatments for the condition are primarily conservative (therapies, non-steroidal anti-inflammatory medications, and steroid injections), with surgical resection being reserved for refractory cases.
