The purpose of this cohort study is to determine the incidence of all congenital vertebral anomalies detected antenatally through ultrasound. We also reported on the early mortality rate for this patient cohort, as well as the frequency and type of associated congenital anomalies.

The East Midlands and South Yorkshire Anomalies Register consists of data on all voluntary reports of congenital anomalies, from an annual baseline birth rate of 67000 births. We analysed all registered congenital anomalies reported over a 10 year period.

Between January 1997 and January 2007, 108 vertebral anomalies were reported, excluding spinal dysraphism (incidence 0.01%). 61 of these were detected antenatally (56%), 17 were detected postnatally (16%) and in 30 patients, the precise time of diagnosis was unclear (28%).

At the time of analysis January 2007, 45 of 108 patients had died, either in utero or soon after delivery (42%). 12 fetuses remained in utero and 51 infants were alive. The mortality rate for antenatally diagnosed patients was 41% and the majority were electively terminated (72%). 2 fetuses electively terminated had vertebral anomalies in isolation.

There is a relatively high incidence of elective termination of pregnancy as a result of antenatal anomaly ultrasound screening. We have evidence to suggest that foetuses with potentially minor congenital anomalies are being electively terminated at approximately 18 weeks gestation. A structured and timely spinal counselling should be offered once antenatal vertebral anomalies have been identified.

Our aim was to judge the influence of preoperative psychological disturbance on the outcome of lumbar discectomy. We evaluated 66 patients, before and after operation, using a self-administered questionnaire. Disability was assessed using the Oswestry disability index and psychological disturbance the Distress and Risk Assessment Method (DRAM) score. Patients were classified as normal, at risk or distressed, and the outcome of surgery in the three groups was compared at a follow-up of six months. The mean self-reported preoperative disability was significantly higher in those with psychological disturbance. A total of 54 patients (82%) returned completed postoperative questionnaires. Postoperative disability scores at six months were not significantly different in the three risk groups. Psychological disturbance improved after surgery. Our study suggests that the early outcome of lumbar discectomy is not affected by preoperative psychological disturbance. We conclude that a patient with a symptomatic prolapsed intervertebral disc should not be denied surgery on the basis of preoperative psychological assessment

Objectives

Although vertebroplasty is very effective for relieving acute pain from an osteoporotic vertebral compression fracture, not all patients who undergo vertebroplasty receive the same degree of benefit from the procedure. In order to identify the ideal candidate for vertebroplasty, pre-operative prognostic demographic or clinico-radiological factors need to be identified. The objective of this study was to identify the pre-operative prognostic factors related to the effect of vertebroplasty on acute pain control using a cohort of surgically and non-surgically managed patients.

The outcome of surgery for recurrent lumbar disc herniation is debatable. Some studies show results that are comparable with those of primary discectomy, whereas others report worse outcomes. The purpose of this study was to compare the outcome of revision lumbar discectomy with that of primary discectomy in the same cohort of patients who had both the primary and the recurrent herniation at the same level and side.

A retrospective analysis of prospectively gathered data was undertaken in 30 patients who had undergone both primary and revision surgery for late recurrent lumbar disc herniation. The outcome measures used were visual analogue scales for lower limb (VAL) and back (VAB) pain and the Oswestry Disability Index (ODI).

There was a significant improvement in the mean VAL and ODI scores (both p < 0.001) after primary discectomy. Revision surgery also resulted in improvements in the mean VAL (p < 0.001), VAB (p = 0.030) and ODI scores (p < 0.001). The changes were similar in the two groups (all p > 0.05).

Revision discectomy can give results that are as good as those seen after primary surgery.

Spinal stenosis and disc herniation are the two most frequent causes of lumbosacral nerve root compression. This can result in muscle weakness and present with or without pain. The difficulty when managing patients with these conditions is knowing when surgery is better than non-operative treatment: the evidence is controversial. Younger patients with a lesser degree of weakness for a shorter period of time have been shown to respond better to surgical treatment than older patients with greater weakness for longer. However, they also constitute a group that fares better without surgery. The main indication for surgical treatment in the management of patients with lumbosacral nerve root compression should be pain rather than weakness.
