Recurrent dislocation of the hip in adult paraplegics.

Recurrent dislocation of the hip is rare and has not previously been reported in adult paraplegics. This paper describes 3 cases. In one patient it was spontaneous, occurring 16 years after the original injury and was associated with a flexion-adduction contracture of the hip and a shallow acetabulum. One case occurred after minor trauma in a patient who experienced flexion-adduction spasms of the hip. In the third patient the condition was secondary to posterior acetabular deficiency following a conservatively treated fracture dislocation. All 3 patients experienced symptoms of disabling autonomic dysreflexia during the episodes of dislocation. The importance of recognising and adequately treating hip injuries in patients presenting with paraplegia secondary to spinal cord injury is stressed. In patients with spastic paraplegia presenting with recurrent dislocation of the hip, operative treatment combining a soft tissue repair and a bone block to augment the acetabulum is recommended.

Dillwyn Evans operation for relapsed club foot. Long-term results.

We reviewed the long-term results of the Dillwyn Evans procedure for club foot in 60 feet of 45 patients with an average age of 29 years, using four different scoring systems. The results at 12 to 38 years were compared with those of an earlier study of the same group of patients. Function was satisfactory in 68% of feet; 90% of the patients were able to perform all desired activities. Mild residual deformity was compatible with satisfactory function, and poor function was related to ankle and subtalar stiffness. Our results suggest that this procedure has a low rate of deterioration and degenerative change with time.

A solution for arthroscope misting.

A prospective study was undertaken to compare the incidence of arthroscope eyepiece misting in two groups of patients. In one group the irrigation fluid was at room temperature and in the other group the fluid was warmed to body temperature. Arthroscope eyepiece misting was eliminated when irrigation fluid at body temperature was used.

Comparison of clinical tests and the KT1000 in the diagnosis of anterior cruciate ligament rupture.

A prospective study was undertaken to compare the accuracy of the Lachman test, anterior drawer test and jerk test with the KT1000 knee arthrometer in patients with proven anterior cruciate ligament deficiency. The Lachman and anterior drawer tests were found to be the most accurate indicators of anterior cruciate ligament deficiency. The KT1000 knee arthrometer was found to be totally inaccurate, which precludes its use as an objective measure of anteroposterior laxity of the knee.

Preparation of skin for surgery.

A survey of 113 hospitals in the UK was performed to assess current practices regarding skin preparation for surgery. The findings of the survey are presented and where relevant compared with a similar survey conducted in 1983. It was found that, despite scientific evidence supporting change, traditional practices still dominate. This evidence is discussed and, based on this, some changes in practice are suggested.

Radiological sign of chronic anterior cruciate ligament deficiency.

An early radiological sign of anterior cruciate ligament deficiency is described. A retrospective study of the radiographs of 38 patients with chronic anterior cruciate ligament deficiency was performed. In 36 patients from this group an osteophyte was present on the medial femoral condyle adjacent to the medial tibial spine. This was best seen on a 30 degree notch view and was the earliest radiographic sign of chronic anterior cruciate ligament deficiency.

Effect of delay in processing on lysis-centrifugation blood culture results from marrow transplant patients.

The effect of delay in processing on results of lysis-centrifugation (LC; Isolator) blood cultures was assessed in 4,577 paired blood specimens. Blood specimens were obtained at all hours from 384 febrile marrow transplant patients with indwelling venous catheters and were processed by the LC technique and by a conventional two-bottle method. Most patients (84%) were receiving broad-spectrum antibiotics at the time of blood culture. Specimens were delivered to the laboratory, where Isolator tubes were held at 35 degrees C and processed in batches between 0700 and 1730 h daily. This procedure resulted in a delay beyond the manufacturer-suggested processing time of less than 8 h for 1,853 (42%) of the LC cultures. There was no overall difference in the recovery of organisms present in LC cultures processed after being held for 8 to 24 h compared with the conventional two-bottle method. LC methodology had shorter time to detection than the conventional method for detection of Candida spp. and Pseudomonas spp. (P less than 0.05). However, time to detection for Streptococcus spp. and members of the family Enterobacteriaceae, responsible for 16.3% of total isolates, was prolonged significantly by delay in processing when compared with the conventional two-bottle method (P less than 0.01). Results of this study support the recommendation of the manufacturer for processing of Isolator tubes within 8 h or less. Although one can safely delay processing beyond 8 h in terms of total recovery of organisms, such delays were associated with longer time to detection for certain important potentially pathogenic organisms which accounted for a sizeable proportion of blood culture isolates from marrow transplant patients.
