Lumbar spinal manipulation on trial. Part I--clinical assessment.

Thirty-two patients with chronic low back pain were treated three times at weekly intervals with rotational manipulation. Patients with femoral or sciatic root pain were included provided they did not exhibit root compression signs. Background therapy of codeine phosphate was administered throughout. There was a significant increase in spinal flexion measured clinically during the three-week period of manipulation followed by a significant decrease in the three-week period after manipulation. The first week of manipulative treatment was more painful than the corresponding week in the control group but in the second and third weeks there was less pain in the manipulated group. Pain scores were reduced to a significant degree within four weeks of starting treatment only in the group manipulated in the first treatment period. Patients benefitting subjectively from manipulation were more likely to be older and to have had symptoms for a shorter period than those not deriving benefit. The age of onset of symptoms was significantly later in the responders.

Lumbar spinal manipulation on trial. Part II--radiological assessment.

In a trial of manipulation for chronic low back pain, radiographs of the lumbar spine and radiographic assessment of spinal motion were of no value in predicting or assessing the response of the patients to manipulation. Although radiography of the lumbar spine is a commonly requested investigation, it contributes little to the management of such patients except to exclude serious spinal pathology before any form of physical treatment is commenced.

The radiology of the hip joints and pelvis in cerebral palsy.

Thw radiological appearances found in the pelvis and hip joints in 79 patients with cerebral palsy, aged 5--16 years, have been studied. These findings have been recorded and correlated with the clinical severity and distribution of the disease. Subluxation of the hip joints was found in 14% and dislocation in a further 6%. Spasticity was the predominant neuromuscular handicap in 69 out of 79 cases (88%). The acetabular angle and femoral neck shaft angle were related to the degree of migration of the femoral head. The acetabular angle, iliac angle, iliac index and femoral neck shaft angle were all significantly increased in the deranged group. In the dislocated group, the mean neck-shaft angle was 154 degrees. When the degree of spasticity was asymmetrical, there was a striking relationship between the laterality of the spasticity and the laterality of the deranged hip, pelvic obliquity and increased acetabular angle. A typical teardrop-shaped femoral head was seen in 48% spina bifida occulta of the lower lumbar and sacral spine in 32% and pseudoarthrosis in 3.8%. No ectopic calcification or ossification of soft tissue was noted. An awareness that these children are at risk from subluxation and dislocation of the hip and the importance of early diagnosis and treatment are emphasised.

A trial of micro-encapsulated and enteric-coated aspirin in rheumatoid arthritis.

In a trial of 48 patients with rheumatoid arthritis, enteric-coated aspirin (4.55 g daily( and micro-encapsulated aspirin (4.50 g daily) proved to be equally effective in reducing morning stiffness, relieving pain, increasing grip strength, reducing ESR, and reducing the need for additional analgesic tablets, compared with placebo. Reduction of joint tenderness was also found, but this was not statistically significant. Proximal interphalangeal joint circumference altered little during the trial. Tinnitus and deafness were commoner with enteric-coated aspirin, but gastric side-effects were similar. Of 39 patients completing the trial, there was an equal patient preference for enteric-coated aspirin and micro-encapsulated aspirin. Salicylate side-effects necessitated withdrawal of six patients from the trial and dose reduction in nine patients. It was concluded that the efficacy and side-effects in rheumatoid arthritis of both aspirin preparations were similar.

Reactions to total dose infusion of iron dextran in rheumatoid arthritis.

Ten patients with active rheumatoid arthritis were given a total dose infusion of iron dextran for anaemia. One had an immediate anaphylactoid reaction; the other nine had a brief exacerbation of arthralgia and joint dysfunction of up to seven days' duration. The erythrocyte sedimentation rate rose by an average of 23 mm. in one hour (Westergren), but this often took longer than seven days to settle to the preinfusion level.It is suggested that this response is probably not due to an exacerbation of rheumatoid arthritis but to a delayed hypersensitivity reaction to the dextran portion of the iron dextran complex. This treatment is potentially dangerous in rheumatoid arthritis; we recommend a preliminary test dose and that the infusion be started very slowly under supervision.
