An analysis of radiating pain at lumbar discography.

This study aimed to identify the morphological abnormalities of the intervertebral disc, as demonstrated by lumbar discography, that are associated with pain radiation to the hip, groin, buttock or lower limb. We carried out a retrospective review of 99 consecutive lumbar discogram reports. The association of disc degeneration, annular tears (partial or full thickness) and the level of disc injected was determined with respect to the presence and pattern of radiating pain.

Technetium-99m human immunoglobulin imaging in patients with subacromial impingement or adhesive capsulitis.

Although recognised as useful in detecting soft-tissue inflammation and infection, technetium-99m human immunoglobulin (Tc-99m HIG) has not been widely studied in evaluating regional inflammatory musculoskeletal conditions. Tc-99m HIG scintigraphy was undertaken for consecutive patients referred to a rheumatology clinic with unilateral shoulder pain, diagnosed with either subacromial impingement (n = 12) or adhesive capsulitis (n = 4) from clinical examination, radiographic, and in some cases arthrographic findings. In all patients there were no differences in Tc-99m HIG images between symptomatic and asymptomatic shoulders.

[Lumbosacral fusion using a femoro-cortical allograft ring].

Aim Of The Study: To evaluate the midterm radiographic behaviour of femorocortical allograftrings (FCA) in lumbosacral fusions in patients with disabling low back pain.

Methods: The radiographs of 41 patients with a minimum follow-up of 2 years were analysed by an independent orthopedic radiologist. The fusion rate was determined on lateral tomograms routinely obtained at 3 months intervals.

Radiology of rickets, osteomalacia and hyperparathyroidism.

In osteoporosis, the amount of mineralized bone is diminished, but the remaining bone is of normal quality. In rickets and osteomalacia the trabeculae are irregularly mineralized, a feature reflected in the X-ray image. In hyperparathyroidism there is generalized and focal bone resorption leading to demineralization and poor definition of bone on the X-ray.

Radiology of metabolic bone disease: osteoporosis.

This is the first in a pair of articles looking at the radiographic appearance of metabolic bone diseases which lead to a loss of bone density known as osteopenia. This article looks at different forms of osteoporosis, a term used to imply a specific pathology and which does not cover all forms of osteopenia.

Effects on the vertebral end-plate of uncomplicated lumbar discography: an MRI study.

The study aimed to identify and characterise changes occurring in the vertebral end-plate on MRI following uncomplicated lumbar discography. MRI was performed immediately before and within 2 h after uncomplicated lumbar discography in 20 consecutive patients undergoing the study as a precursor to possible spinal fusion. Of these, seven patients underwent a further MRI study at a mean of 72 days after discography (range 19-183 days).

The value of lumbar spine magnetic resonance imaging in the demonstration of anular tears.

Study Design: Retrospective review of magnetic resonance imaging and discography in patients investigated for low back pain before spinal fusion.

Objective: To determine the sensitivity of magnetic resonance imaging in the detection of painful anular tears manifested by the high-intensity zone.

Summary Of Background Data: Two studies have produced results showing that magnetic resonance imaging has a high specificity for the detection of painful anular tears manifested by a high-intensity zone.

Alkoxide-Induced Succinate Ester Formation from Alcohols and Bis(trimethylsilyl) 1,2-Bisketene.

Reaction of the 1,2-bisketene (Me(3)SiC=C=O)(2) (1) with alcohols (ROH) catalyzed by LiOR gives rapid and efficient conversion to mixtures of the meso and dl succinates (Me(3)SiCHCO(2)R)(2) (4). There is a change in selectivity with the dl/meso ratio varying from 18/82 with MeOH to 92/8 for t-BuOH. This procedure occurs with minimal desilylation, which is the predominant path in the uncatalyzed reaction.

Anterior lumbar fusion using a hybrid interbody graft. A preliminary radiographic report.

This is a radiographic report of 40 patients (20 men, 20 women) who underwent anterior lumbar interbody fusions (73 levels) utilizing a "hybrid" interbody graft composed of femoral cortical allograft (FCA) bone and iliac crest cancellous autograft bone. The average age at surgery was 38 years (range 17-64 years), and follow-up averaged 1.4 years (range 1.

Comparison of arthrotomographic and magnetic resonance images of 50 temporomandibular joints with operative findings.

Arthrotomography and magnetic resonance imaging (MRI) were carried out on 50 temporomandibular joints (TMJs) in 48 patients who were being considered for surgery for clinically diagnosed internal derangement. The patients presented over a 4-year period with pain and dysfunction which had failed to respond to conservative management. Open surgery was carried out on all TMJs and operative findings compared with the results of imaging.

Metaphyseal abnormalities in fibrodysplasia ossificans progressiva.

Fibrodysplasia ossificans progressiva (FOP) is a rare, congenital disorder characterized by diffuse ossification of extraskeletal connective tissue. The classical features and progression of the disease are described and three cases are presented which fall into the general pattern of FOP clinically and radiologically. A constant feature seen was a slight metaphyseal flaring with spiking at the edges of the metaphyses, compatible with minor alteration in bone morphology during growth.

Comparative study of iohexol and meglumine iothalamate in double-contrast knee arthrography.

A comparison has been made between meglumine iothalamate and a low-osmolar contrast medium, iohexol, in arthrography of the knee. A controlled study evaluated the immediate and delayed patient response as well as the quality of the examination, which was assessed by two radiologists without knowledge of which contrast medium had been employed. The results show that iohexol is a good contrast medium for knee arthrography but offers no advantages to offset the increased cost compared with contrast media in current use.

Abnormal metacarpal heads in brachymesophalangy--report of a case and review of the literature.

A case of brachymesophalangy in which ossicles related to metacarpal heads became detached, causing joint locking, is presented. A distinction has been made by arthrography between this lesion and the loose bodies seen in osteochondritis dissecans, which were previously thought to be the origin of the ossicles and the cause of the locking.

The value or arthrography in the management of internal derangements of the knee: the first 1000 are the worst.

The acceptance of arthrography of the knee as an accurate diagnostic procedure by both radiologists and orthopaedic surgeons in the United Kingdom has been slow compared to many other parts of the world. The value of arthrography in the diagnosis of meniscal lesions is discussed with reference to the first 1000 documented cases in the authors' series. It is considered that the results obtained from such early experience is more relevant to those about to start as an arthrographic service.

Cauda equina syndrome complicating ankylosing spondylitis: use of electromyography and computerised tomography in diagnosis.

A case of the cauda equina syndrome complicating ankylosing spondylitis (AS) is described. An unusual feature of this case was the relapsing and remitting nature of the condition, but there is sufficient evidence to explain the clinical picture on the basis of a recurrent intraspinal inflammatory process. The clinical and radiological features are similar to those of a further 28 reported in the literature.

Radiological assessment of knees in juvenile chronic arthritis (juvenile rheumatoid arthritis).

Radiological changes in the knees were assessed in those patients with juvenile chronic arthritis who still had evidence of knee involvement 5 years after onset of the disease. The patients were grouped according to age and mode of onset. Osteoporosis, modelling abnormalities, growth arrest lines and joint narrowing were found, but erosive change was less common.

Automated screening of antenatal samples using a low ionic strength polybrene system.

The use of a two-channel AutoAnalyzer II system in the routine screening of antenatal sera is described. A low ionic strength polybrene method has been used to give optimum detection of IgG antibodies, and hence the system provides a valuable early detection of such antibodies in pregnancy. Of 88 Rhesus antibodies initially detected on the AutoAnalyzer only and followed up later in pregnancy, 18 (20.

Lognormal distribution of HBsAg strengths in an English population.

The frequency distribution of reverse passive haemagglutination titres for HBsAg in the sera of 78 positive blood donors found furing 2.5-year period closely follows a lognormal distribution curve. This lognormal distribution suggests that the total population of HBsAg-positive donors during this period was approximately 84.
